Description:DESCRIPTION
Technical Field
[001] This disclosure relates generally to a cooling system, and in particular, to a heat exchanging system for enhancing the performance of a radiator.

Background
[002] A radiator is a component used in a cooling system for dissipating heat from a heat generating source. For example, the radiator may be a part of a vehicle that may be used for dissipating heat generated by an engine of the vehicle. The radiator works by transferring heat from the coolant circulating through the heat generating source to the surrounding air. However, the radiator may face several challenges when operating in high-temperature surroundings. For example, in high-temperature environments, the temperature differential between the radiator and the surroundings diminishes, making it more difficult for the radiator to effectively transfer heat. Also, high ambient temperatures can increase the operating temperature of the heat generating source, leading to a higher demand for cooling. If the radiator is unable to dissipate heat efficiently, it may struggle to keep the heat generating source or heating system within the optimal temperature range, resulting in overheating.
[003] Overheating especially in vehicles can have several negative effects, potentially leading to damage or malfunction if not addressed promptly. For example, overheating may lead to reduced engine performance, leading to reduced power output, decreased fuel efficiency, and impaired overall performance. Further, prolonged exposure to high temperatures can cause damage to engine components. Over time, this can lead to reduced engine longevity, increased maintenance costs, and potential engine failure if not addressed.
[004] There is, therefore, a need for solutions for enhancing the cooling performance of the radiator by limiting the ambient temperature. In particular, there is a need for solutions for enhancing the performance of the radiator in dissipating heat.

SUMMARY

The heat exchanging system may include a top reservoir configured to receive and store a fluid, and a bottom reservoir positioned below the top reservoir. The heat exchanging system may further include a plurality of wicks positioned in a region between the top reservoir and the bottom reservoir. The plurality of wicks may be fluidically coupled to the top reservoir and the bottom reservoir. Each of the plurality of wicks may be configured to allow travel of fluid from the top reservoir towards the bottom reservoir along its length.

DETAILED DESCRIPTION
[011] Exemplary embodiments are described with reference to the accompanying drawings. Wherever convenient, the same reference numbers are used throughout the drawings to refer to the same or like parts. While examples and features of disclosed principles are described herein, modifications, adaptations, and other implementations are possible without departing from the spirit and scope of the disclosed embodiments. It is intended that the following detailed description be considered as exemplary only, with the true scope and spirit being indicated by the following claims. Additional illustrative embodiments are listed below.
[012] The present disclosure relates to a heat exchanging system that may be implemented for enhancing cooling efficiency of a radiator. For example, the heat exchanging system may be implemented in a vehicle for enhancing cooling efficiency of a radiator of the vehicle. In such implementations, the heat exchanging system addresses the radiator over-heating issues at engine peak load by providing the additional cooling. To this end, a fluid, for example, water is circulated via the heat exchanging system in front of the radiator, to reduce the air ambient temperature (i.e. around the radiator) by evaporation. Chilled fluid may be optionally used from a Heating, Ventilation, and Air Conditioning (HVAC) system to enhance the cooling effect. A top reservoir is used to store and supply the fluid to the wicks. The leftover water (after evaporation) is collected in a bottom reservoir, to avoid the wastage of water. To enable evaporation, the fluid travels through the wicks via capillary effect. As the fluid travels along the wicks, the ambient air contacting the wicks causes evaporation of fluid. This results in a cooling effect that cools the passing air. The cooled air is then directed to the radiator, to enhance the cooling performance of the radiator.
[013] Additionally, the heat exchanging system implements a functionality of selectively activating some or all of the wicks, depending on the extent of cooling required. During normal operation of the vehicle (for example, when the engine temperature is not very high), only some of the wicks may be activated to assist the radiator. However, when there is a high temperature buildup, for example, during peak engine performance, and the radiator has to remove excessive heat, then all the wicks may be activated, to thereby enhance the efficiency of the radiator. To this end, the heat exchanging system may include a temperature sensor by way of which the ambient temperature and an extent of cooling required can be determined using a controller. The controller may selectively activate valves associated with different chambers of the top reservoir, to thereby selectively activate the wicks associated with the different chambers. Therefore, depending on the extent of cooling required, a proportionate number of wicks may be put into use for facilitating travel of water and evaporation.
[014] By generating the cooling effect, the heat exchanging system improves the performance of the radiator, and may even facilitate downsizing of the radiator. Further, in vehicles, the heat exchanging system helps avoid overheating of the engine and improves fuel economy.
[015] Referring now to FIGs. 1A-1B, a schematic diagram and a perspective view, respectively, of a heat exchanging system 100 are illustrated, in accordance with an embodiment of the present disclosure. The heat exchanging system 100 may be implemented in a vehicle, for example, to remove heat from a region towards a radiator of the vehicle. As will be understood, the radiator may be configured to remove heat from an engine of the vehicle.
[016] The heat exchanging system 100 may include a top reservoir 102 configured to receive and store a fluid. The fluid, for example, may be water. The heat exchanging system 100 may further include a bottom reservoir 104 that may be positioned below the top reservoir 102. In particular, the top reservoir 102 may be positioned at a first elevation, and the bottom reservoir 104 may be positioned at a second elevation lower than the first elevation. In some examples, the bottom reservoir 104 may be positioned vertically below the top reservoir 102. Alternatively, in some embodiments, the bottom reservoir 104 may be positioned below and offset from the top reservoir 102. As such, a region 108 may be defined between the top reservoir 102 and the bottom reservoir 104, such that air may pass through the region 108.
[017] The heat exchanging system 100 may further include a plurality of wicks 106 that may be positioned in the region 108 between the top reservoir 102 and the bottom reservoir 104. The plurality of wicks 106 may be fluidically coupled to the top reservoir 102 and the bottom reservoir 104. For example, the plurality of wicks 108 may be made from Nylon material. Each of the plurality of wicks 108 may include a first end and a second end. The first end may be coupled with the top reservoir 102, such that the first end may contact the fluid in the top reservoir 102. The second end of the wicks may be located in the bottom reservoir 104. Each of the plurality of wicks 106 may be configured to allow travel of fluid from the top reservoir 102 towards the bottom reservoir 104 along its length. In particular, the plurality of wicks 106 may allow the fluid to travel from the top reservoir 102 towards the bottom reservoir 104 via a capillary effect.
[018] The capillary effect, also known as capillary action, is the ability of a fluid to flow in narrow spaces without the assistance of external forces like gravity. The capillary action may occur due to several interrelated factors, including surface tension, adhesion, and cohesion. Surface tension is the tendency of the fluid surface to minimize its surface area. Molecules on the surface of the fluid may experience a net inward force due to unbalanced molecular attractions. Adhesion is the attraction between molecules of different substances. As such, in capillary action, the fluid may be attracted to the material making up the wicks 108. This attraction can be stronger than the cohesive forces within the fluid itself. Cohesion is the attraction between molecules of the same substance. As such, in the fluid, cohesive forces cause the fluid molecules to stick together, and these cohesive forces help pull the fluid upward through the wicks 108. Therefore, when the first end of the wicks 108 is in contact with the fluid in the top reservoir 102, the fluid may start travelling the along the length of the wicks 108 towards the bottom reservoir. The length of the wicks 108 may extend through the region 108.
[019] The plurality of wicks 106 may cause an exchange of heat between air flowing through the region 108 between the top reservoir 102 and the bottom reservoir 104 and the fluid travelling from the top reservoir 102 towards the bottom reservoir 104 along the plurality of wicks 106. This may cause a decrease in temperature of the air flowing through the region 108. As will be appreciated by those skilled in the art, when air comes in contact with the fluid travelling along the plurality of wicks 108, the air may cause evaporation of at least some of the fluid. During evaporation, the fluid undergoes a phase transition from the liquid phase to the gaseous phase, thereby absorbing heat energy from the surrounding air in the process. This absorption of heat leads to a decrease in temperature of the air. As a result, low temperature air may be directed from the region 108 towards the radiator of the vehicle.
[020] In some embodiments, the top reservoir 102 may include a plurality of chambers 110A, 110B, 110C (also, collectively referred to as plurality of chambers 110). In particular, in the embodiment as illustrated in FIG. 1, the plurality of chambers may include a first chamber 110A, a second chamber 110B, and a third chamber 110C. In other words, the fluid storage capacity of the top reservoir 102 may be divided into the plurality of chambers 110.
[021] The plurality of wicks 106 may include one or more sets of wicks – a first set of wicks 106A, a second set of wicks 106B, and a third set of wicks 106C. As such, the one or more sets of wicks 106A, 106B, 106C may together constitute the plurality of wicks 106. Each of the one or more sets of wicks 106A, 106B, 106C may include an associated plurality of wicks. Each set of wicks may be fluidically coupled with an associated chamber of the plurality of chambers 110. For example, as shown in FIG. 1, the first set of wicks 106A may be fluidically coupled with the first chamber 110A. Further, the second set of wicks 106B may be fluidically coupled with the second chamber 110B, and the third set of wicks 106C may be fluidically coupled with the third chamber 110C of the plurality of chambers 110.
[022] In the above embodiment, the heat exchanging system 100 may further include a plurality of valves 112A, 112B, 112C (also, collectively referred to as plurality of valves 112). For example, each of the plurality of valves 112 may be a solenoid valve. In particular, in the embodiment as illustrated in FIG. 1, the plurality of valves 112 may include a first valve 112A, a second valve 112B, and a third valve 112C. Each chamber of the plurality of chambers 110 may include an associated valve of the plurality of valves 112. Each valve (of the plurality of valves 112) may be configured to selectively couple or decouple a chamber of the plurality of chambers 110 with the associated set of wicks, to thereby allow or disallow travel of fluid from the top reservoir 102 towards the bottom reservoir 104 via the associated set of wicks. For example, as shown in FIG. 1, the first chamber 110A may include the first valve 112A, the second chamber 110B may include the second valve 112B, and the third chamber 110C may include the third valve 112C. As such, the first valve 112A may be configured to selectively couple or decouple the first chamber 110A with the first set of wicks 108A, the second valve 112B may be configured to selectively couple or decouple the second chamber 110B with the second set of wicks 108B, and the third valve 112C may be configured to selectively couple or decouple the third chamber 110C with the third set of wicks 108C.
[023] Therefore, when the first valve 112A is opened, the first chamber 110A may be fluidically coupled with the first set of wicks 108A. As such, the fluid may travel from the first chamber 110A towards the bottom reservoir 104, along the length of the first set of wicks 108A. Similarly, when the second valve 112B is opened, the second chamber 110B may be fluidically coupled with the second set of wicks 108B, and the fluid may travel from the second chamber 110B towards the bottom reservoir 104, along the second set of wicks 108B, and so on.
[024] It should be noted that FIG. 1 and the above description showing three chambers 110A, 11B, 11C, three valves 112A, 112B, 112C, and three sets of the wicks is merely exemplary, and the heat exchanging system 100 may include any other number of chambers, valves, and the sets of the wicks.
[025] The one or more of the valves 112A, 112B, 112C, as shown in FIG. 1, may be opened depending on an extent of cooling required for a component that is to receive air cooled by the heat exchanging system 100. The valves 112A, 112B, 112C may be opened individually to thereby put a part of the plurality of wicks 106 in action, to perform the cooling action. By way of an example, the first set of wicks 106A may encompass 30% of the region 108 between the top reservoir 102 and the bottom reservoir 104. Further, the second set of wicks 106B may encompass another 30% of the region 108 between the top reservoir 102 and the bottom reservoir 104. Furthermore, the third set of wicks 106C may encompass remaining 40% of the region 108 between the top reservoir 102 and the bottom reservoir 104. Therefore, when the extent of cooling required is low, only one of the first valve 112A, the second valve 112B, and the third valve 112C may be opened, to thereby cause that associated set of wicks to perform the cooling action. Multiple valves may be opened at the same time to thereby meet a higher extent of cooling required.
[026] In the above example, when only the first valve 112A is opened, only the first set of wicks 106A may allow fluid to travel from the top reservoir 102 to the bottom reservoir 104. Since the first set of wicks 106A encompasses 30% of the region 108 between the top reservoir 102 and the bottom reservoir 104, therefore, the heat exchanging system 100 may generate only 30% of the maximum cooling effect that it can generate. When the extent of cooling required is higher (medium), then both the first valve 112A and the second valve 112B may be opened. As such, the first set of wicks 106A and the second set of wicks 106B may allow fluid to travel from the top reservoir 102 to the bottom reservoir 104. Since the first set of wicks 106A encompasses 30% of the region 108 and the second set of wicks 106B encompasses another 30% of the region, therefore, the heat exchanging system 100 may generate 60% of the maximum cooling effect that it can generate. When the extent of cooling required is even higher (highest), then all the three valves - the first valve 112A, the second valve 112B, and the third valve 112C may be opened. As such, the first set of wicks 106A, the second set of wicks 106B, and the third set of wicks 106C encompassing 100% of the region 108 may perform the cooling action. Therefore, the heat exchanging system 100 may generate 100% of the maximum cooling effect that it can generate. In some embodiments, the opening of the plurality of valves 112 may be controlled automatically using temperature sensors and a controller. This is explained in detail in conjunction with FIG. 2.
[027] As will be understood, some of the fluid traveling through the set of wicks may not evaporate, and therefore reach the bottom reservoir 104 where it may be collected. In some embodiments, the heat exchanging system 100 may include a recycling pipe 114 that may fluidically couple the bottom reservoir 104 with the top reservoir 102. The recycling pipe 114 may therefore allow for recycling of fluid from the bottom reservoir 104 to the top reservoir 102. Further, a pump (not shown in FIG. 1) may be included for pumping the fluid from the bottom reservoir 104 with the top reservoir 102, via the recycling pipe 114.

[028] In some embodiments, in order to further enhance the performance of the heat exchanging system 100, chilled fluid may be used from a Heating, Ventilation, and Air Conditioning (HVAC) system 116. The top reservoir 102 may therefore be connected to the HVAC system 116 of the vehicle to receive the chilled fluid.
[029] Referring now to FIG. 2, a block diagram of a heat exchanging system 200 (corresponding to the heat exchanging system 100) is illustrated in accordance with some embodiments. Similar to the heat exchanging system 100, the heat exchanging system 200 may include the top reservoir 102, the bottom reservoir 104, and the plurality of wicks 106 positioned in the region 108 between the top reservoir 102 and the bottom reservoir 104 (not shown in FIG. 2). The plurality of wicks 106 may be fluidically coupled to the top reservoir 102 and the bottom reservoir 104, such that each of the plurality of wicks 106 may be configured to allow travel of fluid from the top reservoir 102 towards the bottom reservoir 104 along its length. Further, the heat exchanging system 200 may include the plurality of valves 112A, 112B, 112C.
[030] The heat exchanging system 200 may further include a temperature sensor 202 that may be configured to detect an ambient temperature value. For example, the ambient temperature value may relate to temperature in a region towards the radiator of the vehicle where cooling effect is required.
[031] The heat exchanging system 200 may further include a controller 204 that may be communicatively coupled to the temperature sensor 202 and to the plurality of valves 112. The controller 204 may be configured to receive the ambient temperature value from the temperature sensor 202. The controller 204 may be further configured to determine an extent of cooling required for a component that is to receive air cooled by the heat exchanging system 200, based on the ambient temperature value. Further, the controller 204 may be configured activate at least one of the plurality of valves 112, to couple the corresponding chamber with the associated set of wicks, to accordingly allow travel of fluid from the top reservoir 102 towards the bottom reservoir 104 via the associated set of wicks.
[032] To perform the above functionalities, the controller 204 may include a processor 204A and a memory 204B. The memory 204B may be communicatively coupled to the processor 204A. The memory 204B stores a plurality of instructions, which upon execution by the processor 204A, cause the processor 204A to perform the above functionalities.
[033] It should be noted that the memory 204B may be stored with threshold temperature values associated with the different combinations of the sets of wicks required for performing the cooling operation. For example, a first threshold value (t1) may be defined for activating only the first set of wicks 106A; a second threshold value (t2) may be defined for activating the first set of wicks 106A along with the second set of wicks 106B; and a third threshold value (t3) may be defined for activating the first set of wicks 106A, the second set of wicks 106B, and the third set of wicks 106C (here, t1 < t2 > t3). Therefore, during operation, when the detected ambient temperature value is greater than the first threshold value (t1) and less than the second threshold value (t2), then the controller 204 may activate the first valve 112A, to thereby couple the first chamber 110A with the first set of wicks 106A. When the detected ambient temperature value is greater than the second threshold value (t2) and less than the third threshold value (t3), then the controller 204 may activate the first valve 112A and the second valve 112B, to thereby couple the first chamber 110A with the first set of wicks 106A and the second chamber 110B with the second set of wicks 106B. When the detected ambient temperature value is greater than the third threshold value (t3), then the controller 204 may activate the first valve 112A, the second valve 112B, and the third valve 112C, to thereby couple the first chamber 110A with the first set of wicks 106A, the second chamber 110B with the second set of wicks 106B, and the third chamber 110C with the third set of wicks 106C.
[034] Referring now to FIG. 3, a perspective view of a part of a vehicle 300 implementing a heat exchanging mechanism is disclosed, in accordance with some embodiments. The vehicle 300 may include a radiator 302 that may be configured to remove heat from an engine (not shown in FIG. 3) of the vehicle 300 using air received by the radiator 302.
[035] The vehicle 300 may include the top reservoir 102 configured to receive and store a fluid, and the bottom reservoir 104 positioned below the top reservoir 102. In some embodiments, in order to further enhance the performance of the heat exchanging system 300, chilled fluid may be used from a HVAC system 304 of the vehicle 300. The top reservoir 102 may therefore be connected to the HVAC system 304 to receive the chilled fluid.
[036] The vehicle 300 may further include the plurality of wicks 106 that may be positioned upstream of the radiator 302 in an air-flowing direction and in the region 108 between the top reservoir 102 and the bottom reservoir 104. For example, each of the plurality of wicks 106 may be made of Nylon. The plurality of wicks 106 may be fluidically coupled to the top reservoir 102 and the bottom reservoir 104. Each of the plurality of wicks 106 may be configured to allow travel of fluid from the top reservoir 102 towards the bottom reservoir 104 along its length. The plurality of wicks 106 may cause an exchange of heat between air flowing through the region 108 between the top reservoir 102 and the bottom reservoir 104 and the fluid travelling from the top reservoir 102 towards the bottom reservoir 104 along the plurality of wicks 106, to thereby cause a decrease in temperature of the air flowing through the region towards the radiator 302.
[037] In some embodiments, as illustrated in and explained via FIG. 1, the top reservoir 102 may include the plurality of chambers 110. The plurality of wicks 106 may include one or more sets of wicks that may together constitute the plurality of wicks 106. Further, each set of wicks may be fluidically coupled with an associated chamber of the plurality of chambers 110. The vehicle may further include the plurality of valves 112, such that each chamber may include an associated valve of the plurality of valves 112. Each valve of the plurality of valves 112 may be configured to selectively couple or decouple a chamber of the plurality of chambers 110 with the associated set of wicks, to thereby allow or disallow travel of fluid from the top reservoir 102 towards the bottom reservoir 104 via the associated set of wicks.
[038] Further, as illustrated in and explained via FIG. 2, the vehicle 300 may include the temperature sensor 202 that may be configured to detect an ambient temperature value. Further, the vehicle 300 may include the controller 204 that may be communicatively coupled to the temperature sensor 204 and to the plurality of valves 112. The controller 204 may be configured to receive the ambient temperature value from the temperature sensor 202. The controller 204 may be further configured to determine an extent of cooling required for a component that is to receive air cooled by the heat exchanging system 100, based on the ambient temperature value. Further, the controller 204 may be configured to activate at least one of the plurality of valves 112, to couple the corresponding chamber with the associated set of wicks, to accordingly allow travel of fluid from the top reservoir 102 towards the bottom reservoir 104 via the associated set of wicks. Therefore, the associated set(s) of wicks may create a cooling effect to accordingly reduce the temperature of the air passing to the radiator 302.
[039] It should be noted that although the above heat exchanging system is described in the context of vehicles, however, its implementation may not be restricted only vehicles. The heat exchanging system may be implemented in any other application system as well where heat generation exceeds the system's capacity to dissipate it naturally. For example, the heat exchanging system may be implemented in HVAC systems that are used in buildings and vehicles to control indoor temperature and humidity levels. Further, the heat exchanging system may be implemented in data centers housing servers and networking equipment that generate heat during operation. Also, the heat exchanging system may be used in industrial processes, including manufacturing, chemical processing, and power generation that generate significant amounts of heat. Furthermore, the heat exchanging system may be used in aircraft and spacecrafts that generate heat from engines, avionics, and other onboard systems.
[040] One or more techniques are described above for removing heat from a region around the radiator for enhancing the radiator’s cooling efficiency. The above techniques provide for a heat exchanging system that provides for additional cooling in vehicles, to thereby effectively address the radiator over-heating issue at engine peak loads. The techniques reduce the ambient temperature around the radiator zone to improve the cooling performance.
