Description

Technical Field

[0001] This application relates to the field of thermal management technology, and more specifically, to a thermal management integrated component. Background Technology

[0002] The integrated thermal management assembly includes thermal management components, flow channel integration components, and plate heat exchangers. Thermal management components may include, for example, heat exchangers or expansion valves. The flow channel integration components integrate two or more flow channels, enabling communication between the thermal management components. The thermal management components are mounted on the flow channel integration components, which are then mounted on the plate heat exchangers.

[0003] To improve the integration of thermal management integrated components, related technologies install two throttling valves on the flow channel assembly. Plate heat exchangers have four flow channel interfaces, two of which are used to connect to the flow channel assembly, while the other two need to connect to other components or devices. The two throttling valves on the flow channel assembly can easily interfere with other components or devices installed on the other two flow channel interfaces. Therefore, related technologies require improvements to the structure of the flow channel assembly. Summary of the Invention

[0004] Therefore, this application provides a method to reduce the interference caused by two throttling valves installed on the flow channel assembly to other components or devices installed on the plate heat exchanger.

[0005] The thermal management integrated component provided in this application includes a plate heat exchanger, a first throttling valve, a second throttling valve, and a flow channel integrated block. The flow channel integrated block is installed on the plate heat exchanger, and both the first throttling valve and the second throttling valve are installed on the flow channel integrated block.

[0006] The plate heat exchanger has a first heat exchange channel and a second heat exchange channel. The channel integration block has a connecting channel, a first mounting cavity, and a second mounting cavity. The connecting channel connects the first mounting cavity, the second mounting cavity, the first heat exchange channel, and the second heat exchange channel. The first throttling valve portion is located in the first mounting cavity, and the second throttling valve portion is located in the second mounting cavity. The first mounting cavity extends along a first straight line, and the second mounting cavity extends along a second straight line. The first straight line intersects the second straight line.

[0007] The plate heat exchanger includes a first flow channel opening, a second flow channel opening, a third flow channel opening, and a fourth flow channel opening. The first heat exchange flow channel passes through the first flow channel opening and the third flow channel opening, and the second heat exchange flow channel passes through the second flow channel opening and the fourth flow channel opening. The first flow channel opening and the second flow channel opening are connected to the flow channel integrated block, and at least one of the third flow channel opening and the fourth flow channel opening is located between the first straight line and the second straight line.

[0008] In this application, the first and second flow channel openings of the plate heat exchanger are connected to the flow channel integrated block, and the third and fourth flow channel openings can be used to install other components or devices. The first mounting cavity for installing the first throttle valve extends along a first straight line, and the second mounting cavity for installing the second throttle valve extends along a second straight line. The first straight line intersects the second straight line, and at least one of the third and fourth flow channel openings is located between the first and second straight lines, thereby reducing the interference of the first and second throttle valves on other components or devices installed on the plate heat exchanger.

[0024] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] It should be clearly stated that the described technical solutions are only a part of the technical solutions in this application, not all of them. Based on the technical solutions in this application, all other technical solutions obtained by a person skilled in the art without inventive effort are within the scope of protection of this application.

[0026] The thermal management integration assembly 100 includes thermal management components and flow channel integration components. The thermal management components may be, for example, heat exchangers, throttling valves, etc., and the flow channel integration components integrate two or more flow channels to enable communication between the thermal management components. The thermal management integration assembly 100 can improve the integration level of the thermal management system 1000. However, related technologies require further improvements to the thermal management integration assembly 100 to reduce the cost of the corresponding thermal management system 1000.

[0027] The inventors discovered that, in order to reduce clogging of the throttle valve, related technologies include installing a filter device 5 before the throttle valve, allowing the fluid to pass through the filter before flowing into the throttle valve. Some thermal management systems 1000 include at least two throttle valves, thus requiring at least two filter devices 5.

[0028] This application provides a thermal management integrated component 100, for example... Figures 1-10 or Figures 11-14 As shown, this can help reduce the number of filter devices 5 in the corresponding thermal management system 1000, thereby reducing costs.

[0029] The thermal management integrated component 100 provided in this application, for example Figure 1 or Figure 11 As shown, the system includes a plate heat exchanger 1, a first throttling valve 2, a second throttling valve 3, and a flow channel assembly 4. The flow channel assembly 4 is mounted on the plate heat exchanger 1, and both the first throttling valve 2 and the second throttling valve 3 are mounted on the flow channel assembly 4. The plate heat exchanger 1 has a first heat exchange flow channel 11 and a second heat exchange flow channel 12. The first throttling valve 2 has a first valve port 21 and a second valve port 22, one of which is the inlet of the first throttling valve 2, and the other is the outlet of the first throttling valve 2. The second throttling valve 3 has a third valve port 31 and a fourth valve port 32, one of which is the inlet of the second throttling valve 3, and the other is the outlet of the second throttling valve 3. The flow channel integrated block 4 has a first channel 41, a second channel 42, and a third channel 43. The first valve port 21 can communicate with the inner cavity of the filter device 5. The second valve port 22 and the first heat exchange flow channel 11 are both connected to the first channel 41. The second valve port 22 and the third valve port 31 are both connected to the second channel 42. The fourth valve port 32 and the second heat exchange flow channel 12 are both connected to the third channel 43. Alternatively, the first channel 41 connects the second valve port 22 and the first heat exchange flow channel 11, the second channel 42 connects the second valve port 22 and the third valve port 31, and the third channel 43 connects the fourth valve port 32 and the second heat exchange flow channel 12.

[0030] The thermal management integrated component 100 provided in this application includes a flow channel integrated block 4, which has a first channel 41, a second channel 42, and a third channel 43. The second valve port 22 of the first throttling valve 2 and the first heat exchange flow channel 11 are both connected to the first channel 41. The second valve port 22 of the first throttling valve 2 and the third valve port 31 of the second throttling valve 3 are both connected to the second channel 42. The fourth valve port 32 and the second heat exchange flow channel 12 are both connected to the third channel 43. Furthermore, the first valve port 21 can communicate with the inner cavity of the filter device 5. In this way, the first throttling valve 2 and the second throttling valve 3 can share the filter device 5, which is beneficial to reducing the number of filter devices 5 in the thermal management system 1000 corresponding to the thermal management integrated component 100, thereby reducing the cost of the thermal management system 1000 corresponding to the thermal management integrated component 100.

[0031] It is understood that the plate heat exchanger 1 included in the thermal management integrated component 100 of this application is a subcooled heat exchanger. Within the plate heat exchanger 1, the first heat exchange channel 11 and the second heat exchange channel 12 are fluidly isolated, and both the first heat exchange channel 11 and the second heat exchange channel 12 are used for the flow of refrigerant. The first throttling valve 2 and the second throttling valve 3 can be, for example, expansion valves, such as electronic expansion valves (EXV).

[0032] In some embodiments, the flow channel integrated block 4 is a single piece. Related technologies use a connecting pipe 7 to connect the first throttle valve 2 and the second throttle valve 3. Because the connecting pipe 7 has multiple weld points, such as welding to the outer pipe 7 of the throttle valve and filter device 5, and welding between the main pipe and branch pipe at branch or confluence points, oxide scale easily forms on the pipe during welding. This oxide scale is easily detached and mixes with the fluid (e.g., refrigerant) flowing through the pipe during the operation of the thermal management system 1000. Therefore, a filter device 5 needs to be installed before both the first throttle valve 2 and the second throttle valve 3 connected by a pipe. This application uses a flow channel integrated block 4, which is a single piece, reducing the number of weld points compared to pipe connections, thereby reducing impurities introduced during the welding process. In other words, the single-piece design of the flow channel integrated block 4 reduces weld points, thus reducing impurities mixed with the refrigerant during the operation of the thermal management system 1000. Therefore, the first throttle valve 2 and the second throttle valve 3 can share the filter device 5 to meet filtration requirements. In some embodiments, the first channel 41, the second channel 42, and the third channel 43 of the flow channel block 4 are all machined or formed using a sand core process. In some embodiments, the flow channel block 4 is made of steel, such as carbon steel or stainless steel; or the flow channel block 4 is made of aluminum alloy. The flow channel block 4 made of steel or aluminum alloy further reduces the generation of impurities during the welding process.

[0033] In some embodiments, the plate heat exchanger 1 includes a plurality of plates stacked together; the thermal management integrated assembly 100 has a first opening 51 and a second opening 52, the first opening 51 connecting a first channel 41 and a first heat exchange flow channel 11, and the second opening 52 connecting a third channel 43 and a second heat exchange flow channel 12. Along the stacking direction of the plurality of plates, the first opening 51 and the second opening 52 are located on the same side of the flow channel integrated block 4, and the first opening 51 and the second opening 52 are located on the same side of the plate heat exchanger 1. This facilitates the connection between the flow channel integrated block 4 and the plate heat exchanger 1.

[0034] In some embodiments, both the first opening 51 and the second opening 52 are disposed on the flow channel integration block 4. For example Figure 10 or Figure 14As shown, the flow channel integrated block 4 includes a first connecting portion 610, a second connecting portion 620, and a body portion 630. Both the first connecting portion 610 and the second connecting portion 620 protrude from the body portion 630. A portion of a first channel 41 is disposed in the body portion 630, and another portion of the first channel 41 is disposed in the first connecting portion 610. A first opening 51 is disposed in the first connecting portion 610. A portion of a third channel 43 is disposed in the body portion 630, and another portion of the third channel 43 is disposed in the second connecting portion 620. There is a gap between the first connecting portion 610 and the second connecting portion 620. The first connecting portion 610 and the second connecting portion 620 are respectively fixedly connected to the plate heat exchanger 1. A second opening 52 is disposed in the second connecting portion 620. The first connecting portion 610 is at least partially located in the first heat exchange flow channel 11, and the second connecting portion 620 is at least partially located in the second heat exchange flow channel 12. That is, the first connecting portion 610 and the second connecting portion 620 are respectively inserted into the plate heat exchanger 1. Further, for example... Figure 8 As shown, the plate heat exchanger 1 includes a side plate 15, which includes a main body 151 and a flange 152. The flange 152 protrudes from the main body 151. The flange 152 includes a first flange 153 and a second flange 154. A first connecting part 610 is at least partially inserted into the first flange 153 and is welded to the first flange 153. A second connecting part 620 is at least partially inserted into the second flange 154 and is welded to the second flange 154.

[0035] In other embodiments, both the first opening 51 and the second opening 52 are disposed in the plate heat exchanger 1, for example, in the flanged portion 152 described above. The first opening 51 is disposed in the first flanged portion 153, and the second opening 52 is disposed in the second flanged portion 154. The first flanged portion 153 is at least partially inserted into the first connecting portion 610, and the second flanged portion 154 is at least partially inserted into the second connecting portion 620. Alternatively, one of the first opening 51 and the second opening 52 is disposed in the flow channel integration block 4, and the other of the first opening 51 and the second opening 52 is disposed in the plate heat exchanger 1. This application does not limit the connection method between the flow channel integration block 4 and the plate heat exchanger 1, as long as the two can be connected to achieve the communication between the first channel 41 and the first heat exchange flow channel 11, and the communication between the third channel 43 and the second heat exchange flow channel 12.

[0036] In some embodiments, the body portion 630 includes a first mounting portion 631 and a second mounting portion 632, a first mounting cavity 45 is disposed in the first mounting portion 631, and a second mounting cavity 46 is disposed in the second mounting portion 632. At least a portion of the first mounting portion 631 and the second mounting portion 632 are spaced apart. This helps to reduce mutual interference when the first throttle valve 2 and the second throttle valve 3 are installed into the flow channel integrated block 4, and also helps to reduce the weight of the flow channel integrated block.

[0037] In some embodiments, the plate heat exchanger 1 has inter-plate flow channels 14 and distribution flow channels 13. The inter-plate flow channels 14 are located between two adjacent plates and include at least two first inter-plate flow channels 141 and at least two second inter-plate flow channels 142. The distribution flow channels 13 include first distribution flow channels 131 and second distribution flow channels 132. At least two first inter-plate flow channels 141 are connected to the first distribution flow channel 131, and at least two second inter-plate flow channels 142 are connected to the second distribution flow channel 132. The first heat exchange flow channel 11 includes at least two first inter-plate flow channels 141 and the first distribution flow channel 131, and the second heat exchange flow channel 12 includes at least two second inter-plate flow channels 142 and the second distribution flow channel 132. The first opening 51 connects the first channel 41 and the first distribution channel 131, and the extending direction of the first channel 41 is parallel to the extending direction of the first distribution channel 131; the second opening 52 connects the third channel 43 and the second distribution channel 132, and the extending direction of the third channel 43 is parallel to the extending direction of the second distribution channel 132, for example... Figure 8 As shown. This reduces the flow resistance between the flow channel assembly and the plate heat exchanger 1. Furthermore, the first channel 41 is coaxial with the first distribution channel 131. Furthermore, the third channel 43 is coaxial with the second distribution channel 132.

[0038] In some embodiments, the second channel 42 has a first connecting port 421 and a second connecting port 422, the first connecting port 421 communicating with the second valve port 22 and the second connecting port 422 communicating with the third valve port 31. The thermal management integrated assembly 100 has a thickness direction T1, and along the thickness direction T1 of the thermal management integrated assembly 100, the flow channel integrated block 4 is at least partially located on one side of the plate heat exchanger 1; along the thickness direction T1, the distance between the second channel 42 and the plate heat exchanger 1 is a constant, the distance between the second valve port 22 and the plate heat exchanger 1 is equal to the distance between the second channel 42 and the plate heat exchanger 1, and the distance between the third valve port 31 and the plate heat exchanger 1 is equal to the distance between the second channel 42 and the plate heat exchanger 1. This helps to reduce the flow resistance of the second channel 42. In some embodiments, the thickness direction T1 of the thermal management integrated assembly 100 is in the same direction as the direction of the stacking of the plurality of plates of the plate heat exchanger 1 described above. In some embodiments, the thickness direction T1 of the thermal management integrated component 100 is perpendicular to the extension direction of the second channel 42.

[0039] In some embodiments, the flow channel integrated block 4 has a first mounting cavity 45, and the first throttle valve 2 includes a first valve port portion 210 and a second valve port portion 220. The first valve port 21 is disposed in the first valve port portion 210, and the second valve port 22 is disposed in the second valve port portion 220. Both the first valve port portion 210 and the second valve port portion 220 are located in the first mounting cavity 45, and both the first valve port 21 and the second valve port 22 are in communication with the first mounting cavity 45. The first channel 41 has a first channel opening 411, and the second channel 42 has a first connecting port 421. Both the first channel opening 411 and the first connecting port 421 are disposed through the wall of the first mounting cavity 45. The first channel opening 411 is farther away from the second valve port portion 220 relative to the first connecting port 421. For example... Figure 5 As shown, the first mounting cavity 45 includes a first sub-mounting cavity 451 and a second sub-mounting cavity 452. A first valve port 210 is located in the first sub-mounting cavity 451, and the first valve port 21 communicates with the first sub-mounting cavity 451. A second valve port 220 is located in the second sub-mounting cavity 452, and the second valve port 22 communicates with the second sub-mounting cavity 452. Both the first channel 41 and the second channel 42 communicate with the second sub-mounting cavity 452.

[0040] In some embodiments, the flow channel integrated block 4 has a second mounting cavity 46, and the second throttle valve 3 includes a third valve port portion 310 and a fourth valve port portion 320. The third valve port 31 is disposed in the third valve port portion 310, and the fourth valve port 32 is disposed in the fourth valve port portion 320. Both the third valve port portion 310 and the fourth valve port portion 320 are located in the second mounting cavity 46, and both the third valve port 31 and the fourth valve port 32 are in communication with the second mounting cavity 46. The second channel 42 and the third channel 43 are both in communication with the second mounting cavity 46. The third channel 43 has a second channel opening 431, and the second channel 42 has a second connecting port 422. Both the second channel opening 431 and the second connecting port 422 are disposed through the wall surface of the second mounting cavity 46. Specifically, the second mounting cavity 46 includes a third sub-mounting cavity 461 and a fourth sub-mounting cavity 462. The third valve port 310 is located in the third sub-mounting cavity 461 and communicates with the third sub-mounting cavity 461. The fourth valve port 320 is located in the fourth sub-mounting cavity 462 and communicates with the fourth sub-mounting cavity 462. The second channel 42 communicates with the third sub-mounting cavity 461 and the third channel 43 communicates with the fourth sub-mounting cavity 462.

[0041] The installation of the first throttle valve 2 and the second throttle valve 3 will be described below.

[0042] In some embodiments, the flow channel integrated block 4 has a connecting channel 40, a first mounting cavity 45, and a second mounting cavity 46. The connecting channel 40 connects the first mounting cavity 45, the second mounting cavity 46, the first heat exchange flow channel 11, and the second heat exchange flow channel 12. A first throttling valve 2 is partially located in the first mounting cavity 45, and a second throttling valve 3 is partially located in the second mounting cavity 46. The first mounting cavity 45 extends along a first straight line L1, and the second mounting cavity 46 extends along a second straight line L2. The plate heat exchanger 1 includes a first flow channel opening 161, a second flow channel opening 162, a third flow channel opening 163, and a fourth flow channel opening 164. The first heat exchange channel 11 passes through the first channel opening 161 and the third channel opening 163, and the second heat exchange channel 12 passes through the second channel opening 162 and the fourth channel opening 164. The first channel opening 161 and the second channel opening 162 are connected to the channel assembly block 4, and at least one of the third channel opening 162 and the fourth channel opening 164 is located between the first straight line L1 and the second straight line L2. In this way, interference of the first throttle valve 2 and the second throttle valve 3 on the devices or components installed in the third channel opening 162 and the fourth channel opening 164 can be reduced.

[0043] In some embodiments, the thermal management integrated assembly 100 has a thickness direction T1, and along the thickness direction T1 of the thermal management integrated assembly 100, the flow channel integrated block 4 is at least partially located on one side of the plate heat exchanger 1. A plane perpendicular to the thickness direction T1 of the thermal management integrated assembly 100 is defined as a projection plane. The orthographic projection of a first straight line L1 onto the projection plane is a first projection line P1, the orthographic projection of a second straight line L2 onto the projection plane is a second projection line P2, and the orthographic projection of the plate heat exchanger 1 onto the projection plane is a third projection P3. The outer contour of the third projection P3 includes a first straight side C. The third projection P3 has a first central axis O1, which is parallel to the first straight side C. The first projection line P1 forms a first angle with the first central axis O1, and the second projection line P2 forms a second angle with the first central axis O1. The angles α1 of the first angle and α2 of the second angle satisfy the following relationship: 0° < α1 ≤ 90°, 0° < α2 ≤ 90°.

[0044] The plate heat exchanger 1 has a thickness direction T, a length direction L, and a width direction D. Multiple plates are stacked along the thickness direction T of the plate heat exchanger 1, and the thickness direction T, length direction L, and width direction D of the plate heat exchanger 1 are perpendicular to each other. In the application of the thermal management integrated component 100, the length direction L of the plate heat exchanger 1 is perpendicular to the direction of gravity.

[0045] In some embodiments, the angles α1 of the first included angle and α2 of the second included angle satisfy the following relationship: 15° < α1 ≤ 20°, 15° < α2 ≤ 20°. This reduces the influence of gravity on the first throttle valve 2 and the second throttle valve 3, and simultaneously reduces the interference of the installation of the first throttle valve 2 and the second throttle valve 3 on the devices or components installed in the third flow channel opening 162 and the fourth flow channel opening 164.

[0046] For example Figure 2 As shown, along the length L of the plate heat exchanger 1, the first flow channel opening 161 and the second flow channel opening 162 are located on the same side of the plate heat exchanger 1, and the third flow channel opening 163 and the fourth flow channel opening 164 are located on the same side of the plate heat exchanger 1. The first flow channel opening 161 and the third flow channel opening 163 are located on opposite sides of the plate heat exchanger 1. Both the first flow channel opening 161 and the second flow channel opening 162 are connected to the flow channel assembly block 4. Specifically, the first flow channel opening 161 is connected to the first connecting part 610 mentioned above, and the second flow channel opening 162 is connected to the second connecting part 620 mentioned above. The third flow channel opening 163 and the fourth flow channel opening 164 are respectively connected to straight pipes or other components. The setting that the angle between the first projection line P1 and the first straight side C is less than or equal to 20°, and the angle between the second projection line P2 and the first straight side C is less than or equal to 20°, can reduce the interference between the first throttle valve 2 and the second throttle valve 3 and the third flow channel opening 163 and the fourth flow channel opening 164, while ensuring that the height direction of the first throttle valve 2 and the second throttle valve 3 is as parallel as possible to the direction of gravity. The height direction of the first throttle valve 2 is parallel to the extension direction of the first mounting cavity 45. The height direction of the second throttle valve 3 is parallel to the extension direction of the second mounting cavity 46. Specifically, for example... Figure 6 As shown, the angle between the first projection line P1 and the first straight side C is 18°, and the angle between the second projection line P2 and the first straight side C is also 18°. During the design process, while ensuring that the first throttle valve 2 and the second throttle valve 3 do not interfere with the third flow channel inlet 163 connector 7 and the fourth flow channel inlet 164 connector 7, the smaller the angle between the height direction and the gravity direction of the first throttle valve 2, the better. Correspondingly, the smaller the angle between the first projection line P1 and the first straight side C, the better. Similarly, the smaller the angle between the height direction and the gravity direction of the second throttle valve 3, the smaller the angle between the second projection line P2 and the first straight side C, the better.

[0047] In some embodiments, the height direction of the first straight line L1, or the first throttle valve 2, is perpendicular to the thickness direction T1 of the thermal management integrated assembly 100, and the height direction of the second straight line L2, or the second throttle valve 3, is perpendicular to the thickness direction T1 of the thermal management integrated assembly 100.

[0048] In some embodiments, the outer contour of the third projection P3 includes a second straight edge K, and the length of the first straight edge C is greater than the length of the second straight edge K. Along the length direction of the plate heat exchanger, the first flow channel opening 161 and the second flow channel opening 162 are located at the same end of the plate heat exchanger. Along the length direction of the plate heat exchanger, the third flow channel opening 163 and the fourth flow channel opening 164 are located at opposite ends of the plate heat exchanger 1, respectively. A flow channel integrated block is installed at one end of the plate heat exchanger along its length. The first mounting cavity 45 has a first mounting port 453, and the second mounting cavity 46 has a second mounting port 463. Along the length direction of the plate heat exchanger 1, the first mounting port 453 and the second mounting port 463 face the same side of the plate heat exchanger 1.

[0049] In other embodiments, the outer contour of the third projection P3 includes a second straight edge K, and the length of the first straight edge C is less than the length of the second straight edge K. Along the width direction of the plate heat exchanger, the first flow channel opening 161 and the second flow channel opening 162 are located at the same end of the plate heat exchanger, and the flow channel integrated block is installed at one end of the length direction of the plate heat exchanger; the first mounting cavity 45 has a first mounting port 453, and the second mounting cavity 46 has a second mounting port 463. Along the width direction of the plate heat exchanger 1, the first mounting port 453 and the second mounting port 463 face the same side of the plate heat exchanger 1.

[0050] In some embodiments, the thermal management integrated assembly 100 includes a filter connected to a third flow channel opening 163, the filter having a filter chamber 6 communicating with a first heat exchange flow channel 11.

[0051] In some embodiments, the thermal management integrated assembly 100 includes the filter device 5 described above, with a first valve port 21 communicating with the inner cavity of the filter device 5.

[0052] In a first embodiment, the thermal management integrated assembly 100 includes a connecting pipe 7, one end of which is connected to the flow channel integrated block 4, and the other end of which is connected to the filter device 5. Both the first mounting cavity 45 and the inner cavity of the filter device 5 are connected to the pipe of the connecting pipe 7. That is, the filter device 5 is externally connected to the flow channel integrated block 4. The connecting pipe 7 and the flow channel integrated block 4 can be fixedly connected or limitedly connected, or they can be detachably connected, for example, for the purpose of facilitating filter replacement. Specifically, for example... Figure 3 As shown, the flow channel integrated block 4 has a first mounting cavity 45 and a fourth channel 44. The first throttle valve 2 is at least partially located in the first mounting cavity 45, and the first channel 41, the second channel 42, and the fourth channel 44 are all connected to the first mounting cavity 45. For example Figure 3As shown, the first mounting cavity 45 includes a first sub-mounting cavity 451 and a second sub-mounting cavity 452. As described above, the first throttle valve 2 includes a first valve port portion 210 and a second valve port portion 220. The first valve port 21 is disposed in the first valve port portion 210, which is located in the first sub-mounting cavity 451 and communicates with it. The pipe of the connecting pipe 7 is also connected to the first sub-mounting cavity 451.

The first channel 41, the second channel 42, and the fourth channel 44 are all connected to the first mounting cavity 45. The specific installation method of the first throttle valve 2 in the first mounting cavity 45 can be referred to the description of the first embodiment. In the second embodiment, both the first mounting cavity 45 and the filter cavity 6 are connected to the fourth channel 44.

The fourth channel 44 connects the first filter chamber 61 and the first sub-mounting cavity 451. Thus, the fluid first enters the first filter chamber 61, is filtered by the filter screen, enters the second filter chamber 62, and then enters the first sub-mounting cavity 451 through the fourth channel 44 and enters the first valve port 21. In some embodiments, at least a portion of the flow cross-sectional area of ​​the filter chamber 6 is larger than the flow cross-sectional area of ​​the fourth channel 44.

Part of the refrigerant flowing out of the second valve port 22 enters the first distribution channel 131 of the plate heat exchanger 1 through the first channel 41, and is distributed from the first distribution channel 131 to at least two first inter-plate channels 141, and then flows out from the third distribution channel 133; another part enters the third valve port 31 of the second throttling valve 3 through the second channel 42, and then flows out of the second throttling valve 3 from the fourth valve port 32 and enters the second distribution channel 132 of the plate heat exchanger 1, and is distributed from the second distribution channel 132 to at least two second inter-plate channels 142, and then flows out from the fourth distribution channel 134. In the first mode, the first throttle valve 2 does not throttle the refrigerant flowing through it, while the second throttle valve 3 does throttle the refrigerant flowing through it.

[0057] In some embodiments, the thermal management integrated assembly 100 has a second mode in which refrigerant enters a third distribution channel 133 and is distributed from the third distribution channel 133 to at least two first inter-plate channels 141, then enters the first distribution channel 131, and subsequently flows out from the first distribution channel 131 to a first channel 41. A portion of the refrigerant flowing out of the first channel 41 reaches the second valve port 22, flows through the first throttling valve 2, and then flows out from the first valve port 21; another portion of the refrigerant enters the second channel 42 and flows from the second channel 42 to the third valve port 31, passes through the second throttling valve 3, and then flows out from the fourth valve port 32. The refrigerant flowing out from the fourth valve port 32 enters the second distribution channel 132 and is distributed from the second distribution channel 132 to at least two second inter-plate channels 142, and then flows out from the fourth distribution channel 134. In the second mode, both the first throttling valve 2 and the second throttling valve 3 throttle the flow of refrigerant.

The first outer casing 811 is integrally formed with the connecting pipe 83, for example... Figure 7 As shown.
