DETAILED DESCRIPTION OF THE INVENTION

[0017] The following description includes the preferred best mode of one embodiment of the present invention. It will be clear from this description of the invention that the invention is not limited to these illustrated embodiments but that the invention also includes a variety of modifications and embodiments thereto. Therefore, the present description should be seen as illustrative and not limiting.

[0019] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0020] The present invention relates to a heat exchanging device that is capable of providing a means for transferring thermal energy between a primary fluid and a secondary fluid and further agitating the flow of the primary fluid to increase turbulence and enhance the efficiency of heat transfer between the fluids in an efficient manner, thereby enhancing the overall heat exchange process.

[0021] Referring to Figure 1, an isometric view of a heat exchanging device is illustrated, comprising a cylindrical shell 101 composed of three concentrically placed cylindrical housing, wherein primary fluid flows between consecutive surfaces of the housing for heat transfer and within the shell 101 for heat transfer, a primary inlet valve 102 and a primary outlet valve 103 provided at opposing ends of the shell 101, a hollow cylindrical member 104 having a plurality of openings attached with an open end of the shell 101, a plurality of tubes 105 attached on the member 104, a secondary inlet valve 106 and a secondary outlet valve 107 disposed in the member 104 connected with the tubes 105, plurality of semi-circular flaps 108 disposed within the shell 101, the flaps 108 are connected by means of telescopic rods 109 and a container 110 attached with the member configured with a pump 111.

[0022] The proposed device herein comprises of a cylindrical shell 101 composed of three concentrically placed cylindrical housing, wherein primary fluid flows between consecutive surfaces of the housing for heat transfer and within the shell 101 for heat transfer. The cylindrical shell 101 is made up of but not limited to materials such as stainless steel, aluminum or composite alloys chosen for their excellent thermal conductivity, corrosion, resistance and mechanical strength.

[0023] A primary inlet valve 102 and a primary outlet valve 103 is provided at opposing ends of the shell 101 for inflow and outflow of fluids. A hollow cylindrical member 104 is attached to the open end of the shell 101, designed to facilitate the flow of a secondary fluid within the shell 101. The member 104 is made from materials such as stainless steel, aluminum or high-strength polymers selected for their resistance to corrosion, pressure and thermal stresses. The member 104 features multiple precision-engineered openings that align with and securely connect to a plurality of tubes 105.

[0024] The tubes 105 are positioned to extend inward into the shell 101, forming pathways for the secondary fluid to flow and interact thermally with the primary fluid. The tubes 105 are constructed from materials like copper, stainless steel or titanium, known for their high thermal conductivity and durability. A secondary inlet valve 106 and a secondary outlet valve 107 are integrated into the member 104 to control the entry and exit of the secondary fluid. These valves ensure precise regulation of fluid flow, facilitating efficient heat exchange.

[0025] For example; considering the primary fluid as water and the secondary fluid as oil or a refrigerant, the device operates by circulating water through the shell 101 and the secondary fluid through tubes 105 attached to the hollow cylindrical member 104. Water enters via the primary inlet valve 102, flowing between concentric housings where semi-circular flaps 108 create turbulence to enhance heat transfer. The secondary fluid enters the tubes 105 via the member 104 and exchanging heat with water through the tube 105 surfaces. This process ensures efficient heat transfer as water exits the shell 101 and the secondary fluid exits the tubes 105.

[0026] Plurality of semi-circular flaps 108 are positioned inside the shell 101 in a staggered manner, each flap having multiple openings to allow the tubes 105 carrying the secondary fluid to pass through. The flaps 108 are designed to agitate the flow of the primary fluid inside the shell 101, promoting turbulence that enhances heat transfer by increasing fluid contact with heat exchange surfaces. The consecutive flaps 108 are interconnected using telescopic rods 109, which enable the flaps 108 to move in a reciprocating motion.

[0027] The telescopic rod 109 is linked to a pneumatic unit, including an air compressor, air cylinders, air valves and piston which works in collaboration to aid in extension and retraction of the rod 109. The pneumatic unit is operated by an inbuilt microcontroller associated with the device. Such that the microcontroller actuates valve to allow passage of compressed air from the compressor within the cylinder, the compressed air further develops pressure against the piston and results in pushing and extending the piston. The piston is connected with the rod 109 and due to applied pressure, the rod 109 extends and similarly, the microcontroller retracts the rod 109 by closing the valve resulting in retraction of the piston. Thus, the microcontroller regulates the extension/retraction of the flaps 108 to provide reciprocating motion for agitating the primary fluid and intensifying the heat exchange process.

[0028] A container 110 holding a coolant gas is attached to the hollow cylindrical member 104 and is equipped with a pump 111 designed to circulate the coolant gas within the device. The pump 111 operates by drawing the coolant gas from the container 110 and directing it into the member 104, where it absorbs heat from the secondary fluid flowing through the tubes 105. The pump 111 consists of a motor, impeller and inlet/outlet ports. The motor drives the impeller which pressurizes the coolant gas and forces it into the member 104. As the coolant gas moves through the member 104, it absorbs heat from the secondary fluid, lowering its temperature before it exits the device, ensuring efficient thermal management and heat exchange.

[0029] Plurality of flowmeters are installed at each of the primary inlet valve 102, primary outlet valve 103, secondary inlet valve 106, and secondary outlet valve 107 to measure the flow rates of both the primary and secondary fluids. The flowmeter used herein is a turbine flowmeter that works by using a turbine that spins as fluid flows through the meter. The flow of the fluid causes the turbine blades to rotate at a speed proportional to the velocity of the fluid. The turbine is positioned in the fluid path, and as the fluid passes through, it applies force to the blades, causing them to rotate.

[0030] This rotational movement is detected by a magnetic sensor, which measures the number of turbine rotations or the frequency of the rotation. The sensor converts this mechanical motion into an electrical signal, which is processed by the microcontroller to calculate the flow rate. The faster the fluid flows, the faster the turbine spins providing a direct correlation between fluid velocity and flow rate.

[0031] Plurality of temperature sensors are embedded in the shell 101, the tubes 105 and the member 104 to detect temperatures of the primary fluid, secondary fluid and the coolant gas. The temperature sensor used herein is a thermistor-based temperature sensor which consists of a ceramic material with a resistance that varies significantly with temperature. As the temperature of the surrounding fluid (primary fluid, secondary fluid, or coolant gas) changes, the resistance of the thermistor changes in a predictable manner.

[0032] In the case of a Negative Temperature Coefficient (NTC) thermistor, for example, the resistance decreases as the temperature increases. This change in resistance is measured by a circuit and converted into an electrical signal, which is proportional to the temperature of the fluid. The sensor sends this signal to the microcontroller which processes the data and stores it in a database for monitoring and control purposes allowing for accurate temperature tracking in the device.

[0033] Further, an air inflating unit (not shown in the figure) is attached to the inlet valve of the tubes, to flow the air inside the tubes to free the blockage. A threaded round nut is installed to the air inflating unit, to attach with the inlet valve of the tubes. If based on the flow rate, the device detects the blockages (The outlet valve monitors the low-pressure flow of cold fluid), so air inflating unit will engage to the inlet valve to clean the flow.

[0034] The device is associated with a battery for providing the required power to the electronically and electrically operated components including the microcontroller, electrically powered sensors, motorized components and alike of the device. The battery within the device is preferably a lithium-ion-battery which is a rechargeable battery and recharges by deriving the required power from an external power source. The derived power is further stored in form of chemical energy within the battery, which when required by the components of the device derive the required energy in the form of electric current for ensuring smooth and proper functioning of the device.

[0035] The present invention works best in the following manner, where the primary fluid flows through the cylindrical shell 101 passing between the concentric housing surfaces for efficient heat transfer. The primary inlet valve 102 controls the entry of the water into the shell 101, while the primary outlet valve 103 regulates the outflow after the heat exchange process. Simultaneously the secondary fluid is circulated through tubes 105 that are connected to the hollow cylindrical member 104 attached to the open end of the shell 101. The secondary fluid enters through the secondary inlet valve 106 and exits through the secondary outlet valve 107. Inside the shell 101 the plurality of semi-circular flaps 108 are arranged in a staggered manner to agitate the flow of the primary fluid enhancing heat transfer by increasing turbulence. These flaps 108 are connected via telescopic rods 109 which allow for reciprocation, increasing the agitation of the primary fluid as they extend and retract. The shell 101 includes the container 110 filled with coolant gas which is pumped through the member 104 to absorb heat from the secondary fluid. This coolant gas circulates through the member 104 efficiently absorbing the heat transferred from the secondary fluid and maintaining optimal thermal regulation. Temperature sensors embedded within the shell 101, tubes 105 and member 104 continuously monitor the temperatures of the primary fluid, secondary fluid and coolant gas. These sensors which are thermistor-based, detect changes in resistance as the temperature fluctuates, providing real-time data to a microcontroller. This data is stored in a connected database, enabling accurate monitoring and control of fluid temperatures. The system works efficiently by promoting heat exchange between the primary and secondary fluids while the coolant gas ensures that heat is continually absorbed optimizing overall thermal performance.
