The following specification particularly describes the invention and the manner in which it is to be performed.

TECHNICAL FIELD
Present disclosure, in general, relates to a field of automobiles. Particularly, but not exclusively, the present disclosure relates to a cooling system of a vehicle. Further, embodiments of the present disclosure disclose a de-aeration device for the cooling system of the vehicle.
BACKGROUND OF THE DISCLOSURE
Generally, prime movers including, but not limited to, internal combustion engines [also referred to as IC engines] require cooling systems to prevent overheating of the engines and for efficient operation. The cooling systems are generally employed to assist such prime movers through operations such as, but not limited to, removing excess heat and maintain temperature within optimum working range. The cooling systems include hardware components for example, a radiator, a coolant fluid reservoir, a plurality of hoses connecting the radiator and the coolant fluid reservoir to the IC engine, where such hoses are routed inside and/or outside the IC engine for regulating heat dissipated therefrom. Furthermore, a cap is employed to cover an opening defined in the radiator and the cap is defined with valves to allow passage of the coolant from and into the radiator.
Typically, during operation of the prime movers, the coolant within the radiator absorbs heat and expands, thereby increasing pressure in the radiator. With increase in pressure inside the radiator, a valve in the cap of the radiator operates to an open position for discharging a defined quantity of the coolant from the radiator to the reservoir through a hose in order to minimize the pressure inside the radiator. The discharge of coolant from the radiator occurs till the pressure inside the radiator falls to a desired range. Further, during discharging of the coolant, air trapped in the radiator may also flow along with the coolant through the hose into the reservoir. In some instances, the part of air may get trapped again within the hose, when discharge of the coolant from the radiator is stopped. When the prime mover is turned OFF or temperature of the coolant within the radiator reduces, the coolant contracts due to drop in temperature, and vacuum shall be created within the radiator. The vacuum causes the opening of vacuum valve and allows coolant to flow back into the radiator from the reservoir. This return flow continues till the radiator is re-filled with the coolant to negate the vacuum therein.
However, in some instances, due to presence of trapped air pockets in the hose, the flow of coolant into the radiator from the reservoir is restricted, as the trapped air or pockets of air act as a blockage. Also, the vacuum created in the radiator may not provide sufficient suction pressure to suck the

trapped air into the radiator to facilitate flow of coolant back into the radiator. Due to the blockage radiator may be subjected to insufficient replenishment and may result in incomplete filling of the radiator. The incomplete filling of fluid in the radiator may lead to inefficient performance of the radiator and may lead to issues such as overheating and failure of the IC engine, which is undesired.
Present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the known arts.

DETAILED DESCRIPTION
The foregoing has broadly outlined the features and technical advantages of the present disclosure in order that the detailed description of the disclosure that follows may be better understood. Additional features and advantages of the disclosure will be described hereinafter which forms the subject of the claims of the disclosure. It should be appreciated by those skilled in the art that, the conception and specific embodiments disclosed may be readily utilized as a basis for modifying other devices, systems, assemblies and mechanisms for carrying out the same purposes of the present disclosure. It should also be realized by those skilled in the art that, such equivalent constructions do not depart from the scope of the disclosure as set forth in the appended claims. The novel features which are believed to be characteristics of the disclosure, to its device or system, together with further objects and advantages will be better understood from the following description when considered in connection with the accompanying figures. It is to be expressly understood, however, that each of the figures is provided for the purpose of illustration and description only and is not intended as a definition of the limits of the present disclosure.
The terms “comprises”, “comprising”, or any other variations thereof, are intended to cover a non¬exclusive inclusions, such that a system or a device that comprises a list of components or steps does not include only those components or steps but may include other components or steps not expressly listed or inherent to such setup or device. In other words, one or more elements in a system or apparatus proceeded by “comprises… a” does not, without more constraints, preclude the existence of other elements or additional elements in the system or apparatus.
In accordance with various embodiments of the present disclosure, a cooling system of a vehicle is disclosed. The cooling system may include a radiator with a radiator cap and a reservoir. Further, the cooling system may include a de-aeration device that may be fluidly connected between the radiator and the reservoir. The de-aeration device may be fluidly connected to the radiator and the reservoir through a fluid channelizing conduit such as, but not limiting to a hose. The de-aeration device may include a body that may be defined with a first portion having a cylindrical profile and

a second portion extending from a top surface of the first portion having a conical profile. Further, the de-aeration device may include a first port that may be defined in the body. The first port may be configured to fluidly connect with the radiator for channelizing the fluid between the body and the radiator. The fluid entering the body from the radiator is de-aerated, i.e., air in the fluid is removed. Further, the de-aeration device may include a second port that may be defined in the body at a side opposite to a side at which the first port is defined in the body. The second port may be configured to fluidly connect with the reservoir for channelizing a de-aerated fluid between the body and the reservoir. In an embodiment, the first port may be defined at a location higher than the second port. This configuration may facilitate effective de-aeration of the fluid entering into the body from the radiator, thereby mitigating air getting trapped in the hose.
Further, the body may be defined with a diameter which may be in the ratio of 5:1 to 7:1 the diameter of the first port and the second port such that a required flow path and space may be created for de-aeration process and prevent air from being channelized into the second port. Furthermore, the body is defined with a height which may be greater than the height of the reservoir such that the fluid level in both the reservoir and the de-aeration device remains constant. This construction and configuration of the de-aeration device makes the de-aeration device simple and compact, thereby results in low-cost manufacturing and easy maintenance. Also, the de-aeration device eliminates the need of valves and complex devices for de-aerating in the cooling systems, thus resulting in a simple cooling system for the vehicles. Additionally, the de-aeration device facilitates hassle-free flow of fluid into the radiator from the reservoir and thus ensuring complete filling of the radiator to prevent incomplete filling of fluid in the radiator and eliminate issues such as overheating and failure of the IC engine.
In an operational embodiment, during operation of the IC engine, as the temperature of the fluid rises (thus, the coolant), the fluid expands, which results in increasing pressure in the radiator. Due to increase in pressure inside the radiator a desired amount of the fluid is discharged out of the radiator. The discharged fluid may enter into the de-aeration device (i.e., the body of the de-aeration device) through the first port of the de-aeration device. The fluid entered into the body may be de-aerated in the body such that, the air or air pockets in the fluid is vented out of the body through the second portion. The de-aerated fluid is then channelized through the second port of the de-aeration device and into the reservoir, where the fluid is temporarily stored. Further, during non-operating condition of the IC-engine or when temperature of the fluid within the radiator reduces, the fluid contracts due to drop in temperature, and vacuum is created within the radiator. The vacuum causes the fluid to flow back into the radiator from the reservoir. Upon creation of the fluid passage back into the radiator, the fluid from the reservoir may be channelized into the

de-aeration device through the second port and may be channelized towards the radiator through the first port thereby re-filling the radiator with sufficient amount of fluid after de-aerating the trapped air present in the cooling system.
Reference will now be made to the exemplary embodiments of the disclosure, as illustrated in the accompanying drawings. Wherever possible, same numerals have been used to refer to the same or like parts. The following paragraphs describe the present disclosure with reference to Figs. 1-3. It is to be noted that the device may be employed in any vehicle including but not limited to a passenger vehicle, a utility vehicle, commercial vehicles, and any other vehicle with an atmospheric recovery tank type cooling system.
A vehicle includes a prime mover such as, an IC engine, which operates by combustion of fuel. The combustion process in the IC engines leads to generation of heat which when exceeds an operating temperature causes damage to internal components of such IC engine. To maintain temperature of the IC engine within an optimum range, a cooling system (200) (the atmospheric recovery tank type cooling system) is included in the vehicle, where such cooling system (200) may be fluidly connected to the IC engine to dissipate heat therefrom. For sake of simplicity vehicle is not illustrated in the Figs.
Figs. 1 and 2 are exemplary embodiments of the present disclosure which illustrates the cooling system (200). The cooling system (200) may broadly include a radiator (1), a reservoir (2) and a de-aeration device (100). In an embodiment, the de-aeration device (100) may be disposed between the radiator (1) and the reservoir (2) and is fluidly connected to both the radiator (1) and reservoir (2). In an embodiment, the radiator (1), the de-aeration device (100) and the reservoir (2) may be fluidly connected through a connecting line (9) such as but not limiting to a conduit, a hose, pipe and the like. In an illustrated embodiment, the cooling system (200) includes at least one de-aeration device (100) and the same cannot be construed as limitation as the cooling system (200) may include more than one de-aeration device (100) based on the requirement. As an example, the fluid may be a coolant liquid, which may be capable of receiving and exchanging heat. Further, the radiator (1) may include an opening, which is communicating with an array of heat exchanging tubes/cores, which may be configured to allow flow of the fluid and one or more radiator fans to dissipate the heat through convection from the heat exchanging tubes/cores. In an embodiment, the opening of the radiator (1) may be covered and sealed by a radiator cap (3).

In an embodiment, the reservoir (2) may be open to atmosphere or the reservoir (2) may be provisioned with a reservoir cap (10) which may facilitate filling of fluid into the cooling system (200). Further, the reservoir cap (10) may be configured to allow air to escape into the atmosphere.
The radiator cap (3) may be defined with at least two channels (not shown in figs) and may be configured to allow the passage of the fluid between the radiator (1) and the reservoir (2), based on variation of pressure within the radiator (1) due to volumetric change of the fluid in the radiator (1). For example, the radiator cap (3) may be configured to allow passage of the fluid from the radiator (1) to the reservoir (2) when the pressure within the radiator (1) increases above a predefined limit due to increase in temperature of the fluid within the radiator (1). Further, the radiator cap (3) may be configured to allow passage of the fluid from the reservoir (2) to the radiator (1), when the fluid pressure within the radiator (1) drops below a predefined limit due to reduction in temperature of the fluid within the radiator (1). In an embodiment, the radiator cap (3) may include at least one one-way pressure valve and one-way vacuum valve disposed in the at least two channels. The one-way pressure valve and the one-way vacuum valve may be adapted to operate based on the fluid pressure within the radiator (1). The one-way pressure valve may be configured to actuate and allow passage of the fluid from the radiator (1) to the reservoir (2) when the fluid pressure within the radiator (1) increases above a predefined limit due to increase in temperature of the fluid within the radiator (1). Further, the one-way vacuum valve is configured to actuate and allow passage of the fluid from the reservoir (2) to the radiator (1). When the fluid pressure within the radiator (1) drops below a predefined limit, a vacuum is created (thus, suction pressure is generated). In an embodiment, the radiator cap (3) may be defined with a single channel and may be defined with a two-way pressure valve to selectively allow the passage of the fluid into and out of the radiator (1) based on the pressure acting on the two-way pressure valves.
In an embodiment, the predefined/threshold limit of the one-way pressure valve or the one-way vacuum valve may be determined based on factors, including, but not limited to, operating parameters of the radiator (1), load acting on the IC engine, specific heat capacity of the fluid/coolant, material of the IC engine, rate of re-circulation of the fluid, and any other factor that tends to modify working period of the system.
Referring now to Figs. 3a and 3b, which illustrates a perspective view of the de-aeration device (100). The de-aeration device (100) may include a body. In an embodiment, the body may include a first portion (4) and a second portion (5) which may extend away from the first portion (4). In an embodiment, the second portion (5) may extend from a top surface of the first portion (4). As an example, the first portion (4) may be defined with a cylindrical profile and the second portion (5)

may be defined with a conical profile. In an illustrated embodiment, the body of the de-aeration device (100) may include any other geometric profile for the first portion (4) and the second portion (5) other than the cylindrical and conical profile as per requirement, that is the body of the de-aeration device (100) may include any profile other than the geometric shape as illustrated in Figs, hence the same should not be considered as a limitation. As apparent from Figs. 3a and 3b, the second portion (5) of the body may be defined with a provision (8), which may be configured to vent air, which is a result of de-aeration of the fluid. In an embodiment, as best seen in Figs. 1 and 2, the provision (8) may be fluidly connected to the reservoir (2). The provision (8) in the body may be connected fluidly to the reservoir (2) through including but not limited to a conduit, a hose, a pipe and the like. In an embodiment, the provision (8) defined in the second portion (5) of the body may be fluidly connected to the reservoir (2) at a location in the reservoir (2) which may be above a maximum fluid level in the reservoir (2), such that the fluid stored in the reservoir (2) cannot reach the conduit connected to the provision (8).
In an embodiment, the provision (8) defined in the body of the de-aeration device (100) may be open to the atmosphere.
In an embodiment, the conical profile of the second portion (5) of the body may be configured to accelerate venting of the air, as a result of de-aeration of the fluid in body, which is being discharged from the radiator (1).
Referring further to Figs. 3a and 3b the de-aeration device (100) may include a first port (6) defined in the body which may be fluidly connected to the radiator cap (3) of the radiator (1). The first port (6) may be configured to channelize the fluid between the body and the radiator (1). That is, the first port (6) may be configured to channelize fluid from the radiator (1) into the body and from the body into the radiator (1). The fluid channelized from the radiator (1) into the body may be de-aerated in the body and the air released due to de-aeration may be vented through the provision (8) defined in the second portion (5). Further, the de-aeration device (100) may include a second port (7) defined in the body at a location opposite to the first port (6). The second port (7) may be fluidly connected to the reservoir (2) and may be configured to channelize the fluid between the body and the reservoir (2). That is, the second port (7) may be configured to channelize fluid from the body into the reservoir (2) and from the reservoir (2) into the body. In an embodiment, the first port (6) may be defined on the body at a location higher than the second port [as seen in Fig. 3b and indicated by (∆)]. In other words, the first port (6) is positioned at an elevation with respect to location of the second port (7). This configuration of positioning of the first port (6) at an elevation than the second port (7) facilitates in positioning the first port (6) closer

to the second portion (5), which enables effective de-aeration of the fluid, by mitigating the chances of fluid containing air from expelling out of the body through the second port (7). In other words, positioning the first port (6) closer to the second portion (5) aids in venting of the air from the fluid out of the body through the second portion (5), thereby mitigates chances of the fluid containing air from expelling out of the body through the second port (7).
In an embodiment, diameter of the first port (6) and the second port (7) may be equal. Further, diametrical ratio between the body and the first port (6), the second port (7) ranges from 5:1 to 7:1, that is, the diameter of the body may be in the range of 5:1 to 7:1 the diameter of the first port (6) and the second port. The diameter of the of the body being in the range of 5:1 to 7:1 the diameter of the first port (6) and the second port (7) such that a required flow path and space may be created in the body for de-aeration process and prevent air from being channelized into the second port (7)
In an embodiment, the de-aeration device (100) may be connected between the radiator (1) and the reservoir (2) through the connecting line (9), that is the first port (6) of the de-aeration device (100) may be connected to the radiator cap (3) of the radiator (1) through the connecting line (9). Further, the second port (7) of the de-aeration device (100) may be connected to the reservoir (2) through the connecting line (9).
In an embodiment, the de-aeration device (100) may be defined with a height which may be greater than the height of the reservoir (2). Further, in another embodiment, height of the body of the de-aeration device (100) may be higher than a maximum fluid level in the reservoir (2). The height of the de-aeration device (100) or the body being higher than the maximum fluid level in the reservoir (2) prevents a fluid level in the de-aeration device (100) from exceeding the required level.
In an operational embodiment, during operation of the IC engine, as the temperature of the fluid rises the fluid expands, which results in increasing pressure in the radiator (1). Due to increase in pressure inside the radiator (1) a desired amount of the fluid is discharged out of the radiator (1). The discharged fluid may enter into the de-aeration device (100) (i.e., the body of the de-aeration device) through the first port (6) of the de-aeration device (100). The fluid entered into the body may be de-aerated in the body such that, the air in the fluid is vented out of the body through the second portion (5) [as seen in Fig. 1]. The de-aerated fluid is then channelized through the second port (7) of the de-aeration device (100) and into the reservoir (2), where the fluid is temporarily stored. Further, during non-operating condition of the IC-engine or when temperature of the fluid within the radiator (1) reduces, the fluid contracts due to drop in temperature, and vacuum is created within the radiator (1). The vacuum causes the fluid to flow back into the radiator (1) from

the reservoir (2). Upon creation of the fluid passage back into the radiator (1), the fluid from the reservoir (2) may be channelized into the de-aeration device (100) through the second port (7) and may be channelized towards the radiator (1) through the first port (6) thereby re-filling the radiator (1) [as seen in Fig. 2] with sufficient amount of fluid by de-aerating the trapped air present in the cooling system (200).
In an embodiment, the de-aeration device (100) may always be filled with the fluid such that the channelizing of fluid between the radiator (1) and the reservoir (2) may be facilitated immediately.
In an embodiment, the de-aeration device (100) may be positioned substantially proximal to the radiator (1) or may be positioned adjacent to the radiator cap (3) of the radiator (1), to minimize a length of the connecting line (9) between the radiator (1) (thus, the radiator cap) and the de-aeration device (100) so as to mitigate chances of air getting trapped within the connecting line (9) between the radiator (1) (thus, the radiator cap) and the de-aeration device (100).
In an embodiment, the first portion (4) and the second portion (5) of the body may be integrally formed or may be individual portions, which may be joined by suitable joining techniques.
In an embodiment, the reservoir (2) and the de-aeration device (100) may be configured to operate at an atmospheric pressure.
In an embodiment, the de-aeration device (100) is simple in construction which results in low-cost manufacturing and easy maintenance.
In an embodiment, the de-aeration device (100) is compact and is configured to be retrofitted to a conventional cooling system. Further, the de-aeration device (100) enables venting of trapped air without employment of valves and complex de-aeration devices.
In an embodiment, the de-aeration device facilitates removal of trapped air in the cooling system (200) and prevents incomplete filling of the radiator (1) which may lead to overheating and failure of the IC engine.
