Description

Technical Field

[0001] The utility model relates to the technical field of thermal management, in particular to a refrigerant integrated module. Background Art

[0002] Traditional thermal management technology usually adopts a distributed independent structure, which has low space utilization and will cause some energy and space waste. With the rapid development of electric vehicles, people have begun to study vehicle thermal management technology. By coupling various thermal management subsystems, vehicle energy and space can be used more efficiently and the energy consumption of the vehicle can be reduced. At present, thermal management integrated modules are mainly divided into refrigerant side integrated modules, water side integrated modules and the coupling of the two.

[0003] The refrigerant side thermal management integrated module is mainly composed of components such as a refrigerant flow plate, a drying tank (or a gas-liquid separator), a sensor, a battery cooler, a water-cooled condenser, and various valves, among which the drying tank (or a gas-liquid separator), a sensor, a battery cooler, a water-cooled condenser, and various valves are assembled on the refrigerant flow plate. The refrigerant flow plate in the prior art is provided with a joint on the outside for assembling various valves (plug-in type) and sensors and other functional parts, and is provided with a flow channel inside for the flow of the refrigerant medium. The refrigerant flow plate currently used in the refrigerant side integrated module is manufactured by one-piece die-casting, and the remaining components are connected by bolts and the like. However, the integrated module of the prior art has the following disadvantages:

[0004] 1. High cost: Die-casting materials have limitations, and special die-casting aluminum materials must be selected (the content of Si and Mg elements must be controlled at a low level); the mold cost is high; in order to ensure the airtightness of the functional parts assembly position, machining is required after die-casting.

[0005] 2. Heavy weight: The refrigerant flow channel plate is die-cast as a whole. In order to ensure air tightness, the internal flow channel wall thickness is designed to be thicker and heavier.

[0006] 3. Low pass rate: Existing die-casting materials have low fluidity, are prone to pores, and have a low pass rate.

[0007] 4. Heat loss: The cost of die casting is relatively high. In order to further reduce the cost, the high-pressure flow channel and the low-pressure flow channel are designed to be relatively compact and dense, resulting in inevitable heat exchange and thus heat loss. Utility Model Content

[0008] The purpose of the utility model includes, for example, providing a refrigerant integrated module, which can adopt a split assembly structure to combine to form a flow channel plate, thereby improving the problems of high cost, heavy weight and low pass rate in the prior art.

[0014] The end of the flow channel tube can be provided with a connection port, and the connection port can be connected to the mounting seat or the joint.

[0015] In an optional embodiment, the flow channel unit is a semicircular pipe, so that the cross-section of the flow channel is circular.

[0016] In an optional embodiment, there is a gap space between adjacent flow channel units.

[0017] In an optional embodiment, an extension plate is provided at the periphery of the opening groove of the flow channel unit; the extension plates are evenly distributed at the periphery of the opening groove to form a ring shape;

[0018] Furthermore, the extension plate of the flow channel upper plate and the extension plate at the opposite position of the flow channel lower plate can fit each other.

[0019] In an optional embodiment, the extension plate of the flow channel upper plate and the extension plate at a position directly opposite to the flow channel lower plate remain parallel to each other.

That is, such a refrigerant integrated module is processed into a flow tube after being manufactured in a split manner, thereby improving the problems of high cost, high weight, qualified rate and heat damage caused by casting.

[0037] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0038] Please refer to Figure 1 This embodiment provides a refrigerant integrated module, including a flow channel body 100, a mounting seat 200 and a joint 300.

[0039] The flow channel body 100 includes a relatively opposite flow channel upper plate 110 and a flow channel lower plate 120; the flow channel upper plate 110 and the flow channel lower plate 120 each include a plurality of thin-walled flow channel units 400, each flow channel unit 400 has an opening groove 410; the flow channel upper plate 110 and the flow channel lower plate 120 have the same number of flow channel units 400, and their positions correspond one to one;

[0040] The flow channel unit 400 of each flow channel upper plate 110 is connected to the corresponding flow channel unit 400 on the flow channel lower plate 120 to form a tubular flow channel tube 420, and the opening grooves 410 of the flow channel units 400 arranged opposite to each other are enclosed to form a closed flow channel 430; the plurality of flow channel tubes 420 are sequentially connected to form a whole, and the flow channel 430 remains connected to form a circulation flow of the refrigerant medium;

[0041] A connection port may be provided at the end of the flow channel tube 420 , and the connection port may be connected to the mounting seat 200 or the joint 300 .

[0042] Such a refrigerant integrated module includes a flow channel body 100, a mounting seat 200 and a joint 300. The flow channel body 100 includes a relatively opposite flow channel upper plate 110 and a flow channel lower plate 120. The flow channel upper plate 110 and the flow channel lower plate 120 each include a plurality of thin-walled flow channel units 400 of the same number and arranged one-to-one, and each flow channel unit 400 has an open groove 410. Further, when the flow channel upper plate 110 and the flow channel lower plate 120 are connected to each other, the corresponding flow channel units 400 are connected to form a closed flow channel tube 420, and the corresponding open grooves 410 are enclosed to form a sealed flow channel 430. Compared with the prior art method of forming an extended flow channel 430 in a whole plate by casting, the flow channel 430 of this solution is only in the thin-walled flow channel tube 420, and the flow channel tube 420 is connected and assembled in a split structure; there is no casting connection between adjacent flow channel tubes 420 in the prior structure, so that heat can be dissipated in the gap between the flow channel tubes 420, avoiding heat concentration. That is, such a refrigerant integrated module is manufactured in split parts and then processed into a flow tube, thereby improving the problems of high cost, high weight, qualified rate and heat damage caused by casting.

[0043] Furthermore, the refrigerant flow channel 430 plate does not adopt one-piece die-casting, but is changed to a plate stamping and profile machined structure, and the plate thickness is reduced; the mounting seat 200 and the joint 300 can be welded perpendicular to the flow channel 430 plate body, and can also be welded parallel to the flow channel 430 plate body, thereby increasing the flexibility of assembly and maintenance.

[0044] Please continue reading Figure 1 , Figure 2 and Figure 3 , to learn more structural details of the refrigerant integration module.

[0045] The connector 300 is used to connect with other cooling components. The mounting seat 200 is used to install functional components. As can be seen from the figure, there are eleven mounting seats 200 on the flow plate in this embodiment, and they are divided into a first mounting seat 21 to a fourth mounting seat 24. Among them, three first mounting seats 21 are used to install CV, three second mounting seats 22 are used to install PT sensors, three third mounting seats 23 are used to install EXV, and the remaining two fourth mounting seats 24 are used to install SOV. It should be noted that EVX is an electronic expansion valve, CV is a one-way check valve, SOV is a stop valve, and the PT sensor is a temperature sensor.

[0046] Furthermore, because the functions of the mounting seats 200 corresponding to different valve bodies are different, the pressures and temperatures generated are also different. In this embodiment, taking a one-way check valve mounting seat 200 farthest from the electronic expansion valve mounting seat 200 as a reference, the one-way check valve mounting seat 200 and a stop valve mounting seat 200, a PT sensor mounting seat 200, and another one-way check valve mounting seat 200 nearby together enclose a high-temperature and high-pressure area 11, and the remaining parts of the mounting seats 200 enclose a low-temperature and low-pressure area 12. As can be seen from the figure, the low-temperature and low-pressure area 12 surrounds the high-temperature and high-pressure area 11 in a U shape.

[0047] Furthermore, in this embodiment, the shape, structure, and size of the flow channel upper plate 110 and the flow channel lower plate 120 are the same, so it is convenient to manufacture the flow channel body 100 on a large-scale assembly line, thereby improving the versatility of the refrigerant integrated module and reducing costs.

[0048] Optionally, in this embodiment of the utility model, the flow channel unit 400 is a semicircular pipe, so that the cross section of the flow channel 430 is circular. That is, the flow channel tube 420 is a circular tube, and the flow channel 430 is a hollow circular channel. Such an arrangement further simplifies the processing convenience of the flow channel upper plate 110 and the flow channel lower plate 120.

[0049] As can be seen from the figure, in this embodiment of the utility model, there is a gap space 401 between adjacent flow channel units 400. That is, the flow channel tubes 420 are arranged at intervals, so that such a gap space 401 can avoid the problem of heat conduction caused by the heat concentration of the flow channel 430, and the problem of heat damage caused. By isolating or reducing the contact area of ​​the high-temperature and high-pressure part of the refrigerant flow channel 430 plate and the low-temperature and low-pressure part, heat conduction is reduced; by optimizing the flow channel 430 of the flow channel 430 plate body, the problem of high-pressure and low-pressure heat conduction can be effectively solved, thereby optimizing heat loss.

[0050] That is, the flow channel 430 formed by the flow channel upper plate 110 and the flow channel lower plate 120 is hollowed out or the contact surface is reduced so that the high-pressure part is separated from the low-pressure part.

[0051] In this embodiment of the utility model, an extension plate 440 is provided at the periphery of the opening groove 410 of the flow channel unit 400; the extension plates 440 are evenly distributed at the periphery of the opening groove 410 to form a ring; and the extension plates 440 of the flow channel upper plate 110 and the extension plates 440 at the opposite positions of the flow channel lower plate 120 can fit each other. The provision of the extension plates 440 facilitates the smooth connection of the two opposite flow channel units 400, and the extension plates 440 serve the purpose of increasing the structural strength and aligning and guiding.

[0052] Optionally, in this embodiment of the utility model, the extension plate 440 of the flow channel upper plate 110 and the extension plate 440 facing the flow channel lower plate 120 remain parallel to each other, that is, the extension plate 440 and the plane of the opening groove 410 remain horizontal, thereby simplifying the connection of the facing flow channel unit 400.

[0053] Further, in this embodiment of the present invention, the width of the extension plate 440 is smaller than the width of the opening slot 410. Specifically, in this embodiment, the width of the extension plate 440 is smaller than the radius of the opening slot 410.

[0054] In this embodiment of the utility model, the flow channel upper plate 110 and the flow channel lower plate 120 are both stamped by plates, and the flow channel upper plate 110 and the flow channel lower plate 120 can be welded into a furnace to form a sealed flow channel 430. This can reduce the weight and processing difficulty of the flow channel body 100, while ensuring the sealing of the flow channel 430.

[0055] In this embodiment of the utility model, the mounting seat 200 and the joint 300 are configured to be fixed to the flow channel body 100 by riveting or clamping, and then fastened by welding, so that the flow channel 430, the joint 300 or the mounting seat 200 can maintain a good sealing effect.

[0056] Optionally, for the functional parts or connectors 300 that need to be arranged parallel to the flow channel 430 plate body, by respectively stamping the upper and lower flow channel 430 plates into semi-cylindrical shapes, and then inserting the machined functional part mounting seat 200 or connector 300 into the cylindrical shape formed by the upper and lower flow channel 430 plates, both the pressure resistance and the function can be ensured;

[0057] As can be seen from the figure, the refrigerant integrated module also includes a fin structure 500; the fin structure 500 can be selectively arranged on the outer wall of any flow channel unit 400 to increase the heat dissipation area of ​​the flow channel body 100. Optionally, the fin structure 500 is attached to the flow channel unit 400 by welding or bonding. In this embodiment, the fin structure 500 is arranged outside the flow channel tube 420 of the high temperature and high pressure area 11.

[0058] In summary, the embodiment of the utility model provides a refrigerant integrated module, which has at least the following advantages:

[0059] The refrigerant channel 430 plate does not adopt one-piece die-casting, but is changed to a plate stamping and profile machining structure. The plate thickness is reduced, effectively solving the problems of high cost and heavy weight.

[0060] The welding process of sheet metal stamping machine is mature and can effectively solve the problem of low qualified rate.

[0061] By optimizing the flow channel 430 of the plate body, the problem of high and low pressure heat conduction can be effectively solved, thereby optimizing heat loss; adjacent pipes are only connected by pipes, which is different from the existing approximation that is arranged on the entire plate, so that interval spaces are formed between adjacent pipes to achieve heat dissipation.

[0062] The heat dissipation area is increased by the convection channel 430 plate body, thereby reducing power consumption.

[0063] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
