[0035] The heat exchanger of an exemplary embodiment of this application will now be described in detail with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can complement or combine with each other.

[0036] Figures 1 to 22 The illustration shows a thermal management assembly in some embodiments of this application. The thermal management assembly includes a first heat exchanger 1, a second heat exchanger 2, a third heat exchanger 3, and a flow channel plate 4. The first heat exchanger 1, the second heat exchanger 2, and the third heat exchanger 3 are all fixedly connected to the flow channel plate 4. Specifically, the first heat exchanger 1 is attached to the flow channel plate 4, the second heat exchanger 2 is attached to the flow channel plate 4, and the third heat exchanger 3 is attached to the flow channel plate 4.

[0037] The thermal management component has multiple passages, which are slots and / or channels formed in the flow channel plate 4. The flow channel plate 4 has a mounting surface. The first heat exchanger 1 is fixedly connected to the mounting surface, the second heat exchanger 2 is fixedly connected to the mounting surface, and the third heat exchanger 3 is fixedly connected to the mounting surface.

[0038] The third heat exchanger 3 has a first flow channel 301 and a second flow channel 302, both of which can circulate refrigerant. Multiple passages connect at least the chamber of the first heat exchanger 1, the first flow channel 301, the chamber of the second heat exchanger 2, and the second flow channel 302. In this application, the first heat exchanger 1, the second heat exchanger 2, and the third heat exchanger 3 are integrated into the flow channel plate 4 and can be interconnected through the passages in the flow channel plate 4, thereby saving connecting pipes and reducing the risk of refrigerant leakage. Furthermore, the reduction in connecting pipes between the third heat exchanger 3 and the first and second heat exchangers 1 and 2 can also reduce the pressure drop of the refrigerant in the system, thereby improving the coefficient of performance (COP) in the thermal management system.

[0039] The aforementioned first heat exchanger 1, second heat exchanger 2, and third heat exchanger 3 are integrated on the flow channel plate 4 and can be interconnected through passages opened in the flow channel plate 4, thereby saving piping connections and reducing the risk of leakage from the thermal management components. Furthermore, it improves the connection reliability of the thermal management components, effectively saves space, and simplifies the system loop.

[0040] In some embodiments of this application, the first heat exchanger 1 has a third flow channel 101 and a fifth flow channel 102, and the second heat exchanger 2 has a fourth flow channel 201 and a sixth flow channel 202. The third flow channel 101 and the fifth flow channel 102 are not connected, and the fourth flow channel 201 and the sixth flow channel 202 are also not connected. When the thermal management assembly is operating, refrigerant flows through the third flow channel 101 and the fourth flow channel 201, while coolant flows through the fifth flow channel 102 and the sixth flow channel 202. The refrigerant in the third flow channel 101 exchanges heat with the coolant in the fifth flow channel 102, and the refrigerant in the fourth flow channel 201 exchanges heat with the coolant in the sixth flow channel 202. In the third heat exchanger 3, both the first flow channel 301 and the second flow channel 302 flow with refrigerant, and the refrigerant in the first flow channel 301 exchanges heat with the refrigerant in the second flow channel 302. Figures 23 to 24 As shown in the system loop, the first heat exchanger 1 is the refrigerant, the second heat exchanger 2 is the evaporator, and the third heat exchanger 3 further regulates the refrigerant temperature through heat exchange to improve the COP value of the heat exchange system.

[0041] The passage on the flow channel plate 4 connects the third flow channel 101, the first flow channel 301, the fourth flow channel 201, and the second flow channel 302. The third flow channel 101, the first flow channel 301, the fourth flow channel 201, and the second flow channel 302 carry refrigerant, while the fifth flow channel 102 and the sixth flow channel 202 carry coolant.

[0042] In some embodiments of this application, the first heat exchanger 1, the second heat exchanger 2, and the third heat exchanger 3 are all plate heat exchangers. In some embodiments, the first heat exchanger 1 includes multiple plates, which are generally rectangular in shape. Each plate has a corner hole at each of its four corners, and the corner holes of the multiple plates are aligned to form four channels. When the heat exchanger is working, two of the four channels are fluid inflow channels, and the other two are fluid outflow channels. The multiple plates are stacked to form two non-connected flow channels within the first heat exchanger 1, namely the third flow channel 101 and the fifth flow channel 102. The third flow channel 101 and the fifth flow channel 102 are plate channels, that is, the third flow channel 101 is a flow channel between some of the multiple plates, and the fifth flow channel 102 is a flow channel between other plates. Two of the four channels are connected through the third flow channel 101, and the other two channels are connected through the fifth flow channel 102. Similarly, the structures of the second heat exchanger 2 and the third heat exchanger 3 are the same as or similar to the structure of the first heat exchanger 1. Furthermore, the structure and working principle of plate heat exchangers are well known to those skilled in the art, and will not be described in detail here. The first heat exchanger 1, the second heat exchanger 2, and the third heat exchanger 3 in the accompanying drawings are simplified schematic diagrams and do not show the internal structure of the plate stack of the plate heat exchanger.

[0043] Figures 1 to 4 and Figures 11 to 13The diagram illustrates a flow channel plate 4 in some embodiments of this application. The flow channel plate 4 includes a passage plate, which is plate-shaped, with at least a portion of a plurality of passages located on the passage plate. The passage plate includes the aforementioned mounting surface, which includes a first connecting surface 71 and a first side surface 416. The first connecting surface 71 and the first side surface 416 are located on different sides of the thickness direction of the passage plate, respectively. A first heat exchanger 1, a second heat exchanger 2, and a third heat exchanger 3 are fixedly connected to the first connecting surface 71 and / or the first side surface 416. In some embodiments of this application, the first heat exchanger 1 and the second heat exchanger 2 are attached to the first connecting surface 71, and the third heat exchanger 3 is attached to the first side surface 416, i.e., the first heat exchanger 1 is fixedly connected to the first connecting surface 71, the second heat exchanger 2 is fixedly connected to the first connecting surface 71, and the third heat exchanger 3 is fixedly connected to the first side surface 416. Optionally, both the first heat exchanger 1 and the second heat exchanger 2 are brazed to the first connecting surface 71. Optionally, one side surface of the first heat exchanger 1 is in contact with the first connecting surface 71, and one side surface of the second heat exchanger 2 is in contact with the first connecting surface 71. Optionally, one side surface of the third heat exchanger 3 is in contact with the first side surface 416, and the surface of the third heat exchanger 3 is brazed to the first side surface 416.

[0044] like Figure 1 As shown, the first heat exchanger 1 and the second heat exchanger 2 are located on one side of the passage plate in the length or width direction, and the third heat exchanger 3 is located on the other side of the passage plate in the length or width direction.

[0045] In some embodiments of this application, the passage plate includes a first connecting plate 7 and a first flow channel plate 41. The first connecting plate 7 includes a first connecting surface 71 and a second connecting surface 72, which are located on different sides of the thickness direction of the first connecting plate 7.

[0046] The first flow channel plate 41 includes a first side surface 416 and a second side surface 417, which are located on different sides of the thickness direction of the first flow channel plate 41. A second connecting surface 72 is fitted and connected to the second side surface 417, and at least a portion of the passage is located between the first side surface 416 and the second connecting surface 72. Specifically, the first flow channel plate 41 has a first flow channel groove 4101 and a second flow channel groove 4102 spaced apart, both of which are recessed from the second side surface 417 toward the first side surface 416. The second connecting surface 72 is in contact with the second side surface 417 and is sealed to seal the opening of the first flow channel groove 4101 formed on the second side surface 417, and also seal the opening of the second flow channel groove 4102 formed on the second side surface 417, thereby forming the first flow channel groove 4101 and the second flow channel groove 4102 as channels for fluid flow. The aforementioned multiple pathways include a first flow channel 4101 and a second flow channel 4102. Optionally, the first flow channel plate 41 is an irregular plate-shaped body, which is related to the shape and position of the first flow channel 4101 and the second flow channel 4102. The first flow channel 4101 is a transversely folded strip-shaped groove, and the second flow channel 4102 is a transversely folded strip-shaped groove, with the main design goal of reducing the flow path length of the thermal management component and improving the integration of the thermal management component.

[0047] Optionally, the first connecting surface 71, the second connecting surface 72, the first side surface 416, and the second side surface 417 are all flat, which improves the fit between the surfaces, thereby improving the sealing performance and connection reliability between the surfaces.

[0048] The mounting surface includes a first connecting surface 71 and a first side surface 416. The first connecting surface 71 and the first side surface 416 are located on different sides of the thickness direction of the passage plate. The first heat exchanger 1 and the second heat exchanger 2 are fixedly connected to the first connecting surface 71, and the third heat exchanger 3 is fixedly connected to the first side surface 416.

[0049] Specifically, the first heat exchanger 1 and the second heat exchanger 2 are arranged in parallel. The first heat exchanger 1 includes a first mating surface 15, which is mated to a first connecting surface 71 and welded together to provide a sealing and secure connection. Optionally, the first mating surface 15 and the first connecting surface 71 are brazed together to improve connection reliability. In some embodiments of this application, the first mating surface 15 is located on the side opposite to the refrigerant inlet side of the first heat exchanger 1.

[0050] The second heat exchanger 2 includes a second mating surface 25, which is mated to and welded to the first connecting surface 71, serving a sealing or securing connection. Optionally, the second mating surface 25 and the first connecting surface 71 are brazed together to improve connection reliability. Alternatively, as... Figure 1 and Figure 11 As shown, the first connecting plate 7 is square, and both the first heat exchanger 1 and the second heat exchanger 2 are square. The sum of the areas of the first mating surface 15 and the second mating surface 25 is approximately equal to the area of ​​the first connecting surface 71. That is, the length of the first heat exchanger 1 is approximately equal to or equal to the length of the first connecting plate 7. "Approximately equal" means that the length of the first heat exchanger 1 differs from the length of the first connecting plate 7 by approximately ±10%. The sum of the widths of the first heat exchanger 1 and the second heat exchanger 2 is approximately equal to the width of the first connecting plate 7. "Approximately equal" means that the sum of the widths of the first heat exchanger 1 and the second heat exchanger 2 differs from the width of the first connecting plate 7 by approximately ±10%.

[0051] The third heat exchanger 3 includes a third mating surface 35. In some embodiments of this application, at least a portion of the third mating surface 35 is mated to the first side surface 416, and at least a portion of the third mating surface 35 is welded to the first side surface 416, serving a sealing and connecting function. Optionally, at least a portion of the third mating surface 35 is brazed to the first side surface 416 to improve connection reliability. Optionally, the third heat exchanger 3 is located on one side of the length direction of the first connecting plate 7, and the other side of the length direction of the first connecting plate 7 is used to install other components in the thermal management assembly, improving the integration of the thermal management assembly.

[0052] Figures 5 to 10 and Figures 14 to 22 Multiple passages formed on the flow channel plate 4 in some embodiments of this application are shown. The passages include a first passage 401, a second passage 402, a third passage 403, and a fourth passage 404. Figures 23 to 24 The diagram illustrates the connections between the aforementioned multiple pathways and the first heat exchanger 1, the second heat exchanger 2, the third heat exchanger 3, and other components in the thermal management assembly.

[0053] In one embodiment of this application, as Figures 5 to 10 As shown, the third channel 101 is connected to the first channel 401, the first channel 401 is connected to the first channel 301, the second channel 402 is connected to the first channel 301, the third channel 403 is connected to the fourth channel 201, the second channel 402 is connected to the third channel 403, the fourth channel 404 is connected to the fourth channel 201, and the fourth channel 404 is connected to the second channel 302.

[0054] In another embodiment of this application, the thermal management assembly further includes a valve component 5, which includes a valve core 51. The flow channel plate 4 includes a first connecting block 42, which has a valve cavity 400, and the valve core 51 is located in the valve cavity 400. The valve cavity 400 is located between the second passage 402 and the third passage 403, and the valve component 5 is used to control the disconnection, connection, or partial connection between the second passage 402 and the third passage 403. In some embodiments of this application, the valve component 5 is located at or near the inlet of the fourth flow channel 201 of the second heat exchanger 2.

[0055] Optionally, valve component 5 is an electronic expansion valve, which throttles the high-temperature, high-pressure liquid refrigerant through its orifice, transforming it into a low-temperature, low-pressure mist-like hydraulic refrigerant, thus creating conditions for refrigerant evaporation. Understandably, valve component 5 can also be located at the outlet of the fourth flow channel 201 of the second evaporator 2 to control the refrigerant flow rate, ensuring that the outlet of the second heat exchanger 2 is entirely composed of gaseous refrigerant. If the flow rate is too high, the outlet will contain liquid refrigerant, which may enter the compressor in the heat exchange system and cause liquid slugging; if the refrigerant flow rate is too low, it will evaporate prematurely, resulting in insufficient cooling. Of course, valve component 5 can also be located in other passages within the thermal management assembly as needed; these are not all listed in the embodiments of this application.

[0056] like Figures 14 to 19 As shown, the third flow channel 101 is connected to the first passage 401, the first passage 401 is connected to the first flow channel 301, the second passage 402 is connected to the first flow channel 301, and the third passage 403 is connected to the fourth flow channel 201. The valve component 5 is used to control the disconnection, connection, or partial connection between the second passage 402 and the third passage 403. When the second passage 402 and the third passage 403 are connected or partially connected, the first flow channel 301 is connected to the fourth flow channel 201 through the second passage 402 and the third passage 403. The fourth passage 404 is connected to the fourth flow channel 201, and the fourth passage 404 is also connected to the second flow channel 302.

[0057] like Figures 12 to 19 As shown, the first connecting block 42 is located on the other side of the length direction of the first connecting plate 7, and the first connecting block 42 and the third heat exchanger 3 are located on the same side of the thickness direction of the first connecting plate 7. The first connecting block 42 is fixedly connected to the first connecting plate 7, and the first connecting block 42 is connected to the first flow channel plate 41. Optionally, the first connecting block 42 is brazed to the first connecting plate 7, and the first connecting block 42 is brazed to the first flow channel plate 41. Optionally, the first connecting block 42 is a block-shaped body. The first connecting block 42, the first connecting plate 7, and the first flow channel plate 41 are attached together and at least partially sealed to each other, so that the above-mentioned multiple passages can be connected to prevent leakage.

[0058] The valve chamber 400 is located on one side of the length direction of the first connecting block 42, part of the valve core 51 is located in the valve chamber 400, and another part of the valve core 51 is located between the third heat exchanger 3 and the first connecting block 42.

[0059] In another embodiment of this application, such as Figures 11 to 19 As shown, the thermal management assembly also includes a liquid receiver 6. This liquid receiver 6 stores refrigerant, prolonging the refrigerant's residence time and liquefying the gas in the refrigerant as much as possible. The liquid receiver 6 is connected to the first connecting block 42, and the liquid receiver 6 is sealed to the first connecting block 42. In another embodiment of this application, the liquid receiver 6 is a can-shaped body with a liquid storage chamber 60. It is understood that in some embodiments of this application, the thermal management assembly may not include a liquid receiver 6.

[0060] Figures 20 to 22 A first connecting block 42 is shown in some embodiments of this application. The first connecting block 42 has a first channel 4201 and a second channel 4202, both of which are channels formed in the first connecting block 42. Figure 15 The diagram illustrates the communication relationships between the first channel 4201 and the second channel 4202, and the third flow channel 101 and the first flow channel groove 4101. Specifically, the inlet side of the first channel 4201 is connected to the third flow channel 101, and the outlet side of the first channel 4201 is connected to the liquid storage chamber 60. The inlet side of the second channel 4202 is connected to the liquid storage chamber 60. The outlet side of the second channel 4202 is connected to the first flow channel groove 4101, and the first flow channel groove 4101 is connected to the first flow channel 301.

The outlet of the first heat exchanger outlet 11 is located on one side of the length direction of the first mating surface 15 and on one side of the width direction of the first mating surface 15. Figure 12 As shown, the outlet of the first heat exchanger outlet 11 is located at the lower right corner of the first mating surface 15.

[0062] The first connecting plate 7 has a first connecting hole 73, which penetrates the first connecting plate 7 along its thickness direction. The first connecting hole 73 is located on one side of the length direction and on one side of the width direction of the first connecting plate 7, that is, on... Figure 15 The location is shown in the lower right corner. The first connecting hole 73 is at least partially opposite to the outlet of the first heat exchanger outlet 11. Optionally, both the first connecting hole 73 and the outlet of the first heat exchanger outlet 11 are circular, and the diameters of the first connecting hole 73 and the first heat exchanger outlet 11 are equal, and the first connecting hole 73 and the first heat exchanger outlet 11 correspond completely.

The first connecting block 42 includes a body 420 and a first protrusion 427 and a second protrusion 428 protruding from the aforementioned side, located on different sides along the length of the first connecting block 42. In some embodiments of this application, the body 420 is cuboid, and the first protrusion 427 and the second protrusion 428 are square blocks, both protruding from one side of the body 420 toward the first heat exchanger. The first channel inlet 421 protrudes from the side of the first protrusion 427 toward the first heat exchanger 1 in a direction closer to the first heat exchanger 1. The first channel inlet 421 is cylindrical with a chamber.

[0064] The outer wall of the first channel inlet 421 is sealed to the hole wall of the first connecting hole 73, or the outer wall of the first channel inlet 421 is sealed to the hole wall of the first connecting hole 73 and the inner wall of the outlet of the first heat exchanger outlet 11, so as to realize the communication between the first channel 4201 and the third flow channel 101.

[0065] The first channel 4201 has a first channel outlet, which communicates with the liquid storage chamber 60. The first connecting block 42 includes a first channel outlet portion 422, which has a first channel outlet. The liquid storage container 6 includes a liquid storage inlet portion 61 and a liquid storage outlet portion 62, which are spaced apart on one side along the length of the liquid storage container 6. The first channel outlet portion 422 is sealed to the liquid storage inlet portion 61. The first channel outlet portion 422 protrudes from the other side of the main body portion 420 and is a cylindrical body with a chamber. The other side of the main body portion 420 is the side away from the third heat exchanger 3 along the length of the first connecting plate 7. The outer wall of the first channel outlet portion 422 is sealed to the inner wall of the liquid storage inlet portion 61, thus realizing the communication between the first channel 4201 and the liquid storage chamber 60.

[0066] The second channel 4202 has a second channel inlet, which communicates with the liquid storage chamber 60. The first connecting block 42 includes a second channel inlet portion 423, which has a second channel inlet and is sealed to the liquid storage outlet portion 62.
