[0001] This application relates to the field of thermal management technology, and more specifically to a thermal management component. Background Technology
[0002] In related technologies, a thermal management system includes independently configured heat exchange components and throttling components. The heat exchange components include a heat exchanger and a first expansion valve, while the throttling components include a second expansion valve.

The assembly of thermal management systems in related technologies is relatively difficult. Summary of the Invention
[0003] The inventors discovered that the independent arrangement of the throttling component and the heat exchange component in related technologies is one of the reasons why their assembly is difficult. Because the heat exchange component and the throttling component are independently arranged, they are prone to relative displacement.

[0033] 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.
[0034] In related technologies, a thermal management system includes an independently configured throttling component and a heat exchange component 100. The heat exchange component 100 includes a heat exchanger 2 and a first expansion valve 11, while the throttling component includes a second expansion valve 31. The throttling component and the heat exchange component 100 work together to enable the thermal management system to be used for either cooling or heating. During assembly, the throttling component and the heat exchange component are connected via a connecting pipe 600. The assembly of thermal management systems in related technologies is relatively difficult.
[0035] The inventors have discovered that the independent arrangement of the throttling component and the heat exchange component 100 in related technologies is one of the reasons for the high assembly difficulty of the thermal management system. Because the heat exchange component 100 and the throttling component are independently arranged, they are prone to relative displacement. To facilitate assembly, the heat exchange component 100 and the throttling component need to be positioned separately before being connected by the connecting pipe 600. Therefore, this application provides a thermal management component 1000 in its first aspect, which facilitates a reduction in the assembly difficulty of the corresponding thermal management system.
[0036] The thermal management component 1000 provided in the first aspect of this application includes a first throttling component 1, a second throttling component 3, and a heat exchanger 2, for example... Figures 1 to 17 As shown. The first throttling assembly 1 includes a first expansion valve 11, which has a first throttling channel 10. The first expansion valve 11 is at least partially located in the first throttling channel 10 and can be used to throttle the fluid flowing through the first throttling channel 10. The first throttling channel 10 has a first throttling inlet 101 and a first throttling outlet 102. The second throttling assembly 3 includes a second expansion valve 31, which has a second throttling channel 30. The second expansion valve 31 is at least partially located in the second throttling channel 30 and can be used to throttle the fluid flowing through the second throttling channel 30. The second throttling channel 30 has a second throttling inlet 301 and a second throttling outlet 302. The outer surface of the thermal management assembly 1000 is defined as the first outer surface 1001. The second throttling inlet 301 and the second throttling outlet 302 are both disposed through the first outer surface 1001. For example... Figure 4 , Figure 5 , Figure 11 and Figure 12 As shown. The first throttling assembly 1 and the second throttling assembly 3 are both installed in the heat exchanger 2; the heat exchanger 2 has a first fluid channel 21 and a second fluid channel 22, and the inlet of the first fluid channel 21 is connected to the first throttling outlet 102.
[0037] In this application, since the first throttling assembly 1, including the first expansion valve 11, and the second throttling assembly 3, including the second expansion valve 31, are both installed on the heat exchanger 2, compared with related technologies, the steps of positioning the heat exchange assembly 100 and the throttling assembly separately can be reduced during the assembly process, thereby reducing the assembly difficulty.
[0038] In this application, the first throttling inlet 101 refers to the inlet for the fluid to be throttled to flow into the first throttling channel 10, and the first throttling outlet 102 refers to the outlet for the fluid after throttling by the first expansion valve 11 to flow out of the first throttling channel 10. Similarly, the second throttling inlet 301 refers to the inlet for the fluid to be throttled to flow into the second throttling channel 30, and the second throttling outlet 302 refers to the outlet for the fluid after throttling by the second expansion valve 31 to flow out of the second throttling channel 30. That is to say, in this application, the throttling inlet refers to the inlet for the fluid to be throttled to flow into the throttling channel, and correspondingly, the throttling outlet refers to the inlet for the fluid after throttling by the expansion valve to flow out of the throttling channel.
[0039] In some embodiments, the thermal management system corresponding to the thermal management component 1000 of this application operates in a cooling mode and a heating mode. In the cooling mode, the fluid flows from the second throttling outlet 302 to the second throttling inlet 301, and the second expansion valve 31 does not throttle the fluid; the second throttling channel 30 only serves as a flow path. In the heating mode, the fluid flows from the second throttling inlet 301 to the second throttling outlet 302, and the second expansion valve 31 throttles the fluid. In some embodiments, in cooling mode, fluid flows into the first throttling channel 10 from the first throttling inlet 101, is throttled by the first expansion valve 11, flows out from the first throttling outlet 102, and flows into the first fluid channel 21, where it exchanges heat with the fluid in the second fluid channel 22 in the heat exchanger 2. In heating mode, after the fluid flows out from the first fluid channel 21, it enters the first throttling channel 10 from the first throttling outlet 102. The first expansion valve 11 does not throttle the fluid, and the first throttling channel 10 only serves as a flow path. Then, the fluid flows out from the first throttling inlet 101 from the first throttling assembly 1.
[0040] In this application, the first throttling inlet 101, the first throttling outlet 102, the second throttling inlet 301, and the second throttling outlet 302 can all be connected to the connecting pipe 600 or other components with internal channels.
[0041] In some embodiments, the second throttling assembly 3 includes a mounting base 4, a second throttling channel 30 disposed on the mounting base 4, the outer surface of the mounting base 4 being a second outer surface 400, and both the second throttling inlet 301 and the second throttling outlet 302 penetrating through the second outer surface 400; the mounting base 4 is mounted on the heat exchanger 2, and the second expansion valve 31 is mounted on the mounting base 4, for example... Figure 4 , Figure 5 , Figure 11 and Figure 12 As shown. That is, the second expansion valve 31 is mounted to the heat exchanger 2 via the mounting base 4. In this way, the connection between the second expansion valve 31 and the heat exchanger 2 can be strengthened.
[0042] In some embodiments, the mounting base 4 has a first mounting cavity 41 and a second mounting cavity 42. A second expansion valve 31 is at least partially located in the first mounting cavity 41. The second throttling assembly 3 includes a pressure regulating valve 40, which is at least partially located in the second mounting cavity 42. The second throttling channel 30 includes a first sub-throttling channel 303 and a second sub-throttling channel 304. The first sub-throttling channel 303 connects the second throttling outlet 302 and the first mounting cavity 41, and the second sub-throttling channel 304 connects the second throttling inlet 301 and the first mounting cavity 41. The second throttling assembly 3 has a pressure regulating channel 43, which includes a first sub-pressure regulating channel 44 and a second sub-pressure regulating channel 45. The first sub-pressure regulating channel 44 connects the second throttling outlet 302 and the second mounting cavity 42, and the second sub-pressure regulating channel 45 connects the second throttling inlet 301 and the second mounting cavity 42. The pressure regulating valve 40 can be used to control the unidirectional flow of fluid from the second throttling inlet 301 to the second throttling outlet 302, for example, in combination with... Figures 1-5 or Figures 9-15 As shown. The thermal management component 1000 connects with other components to form a complete thermal management system. In some cases, such as during the transportation of the thermal management system, the second expansion valve 31 is closed, and the fluid pressure on the second throttling inlet 301 side is greater than the fluid pressure on the second throttling outlet 302 side. The higher fluid pressure on the second throttling inlet 301 side can easily cause pipeline deformation or even rupture. Therefore, a pressure regulating valve 40 is needed for pressure regulation. Specifically, the pressure regulating valve 40 is a one-way valve, which controls the unidirectional flow of fluid from the second throttling inlet 301 to the second throttling outlet 302, thereby allowing the fluid on the second throttling inlet 301 side to be depressurized, reducing the risk of corresponding pipeline deformation or even rupture. It can also be understood that the pressure regulating channel 43 serves as a bypass channel for the second throttling channel 30. When the difference between the fluid pressure on the second throttling inlet 301 side and the fluid pressure on the second throttling outlet 302 side reaches a certain value, the pressure regulating valve 40 is opened, and the fluid on the second throttling inlet 301 side flows to the second throttling outlet 302 side through the pressure regulating channel 43, thereby achieving pressure regulation.
[0043] Specifically, for example Figure 5 or Figure 12 As shown, the first sub-pressure regulating channel 44 connects the first sub-throttling channel 303 and the second mounting cavity 42. The first sub-pressure regulating channel 44 has a first sub-opening 441 and a second sub-opening 442. The first sub-opening 441 is disposed through the inner wall of the first sub-throttling channel 303. The second sub-opening 442 is disposed through the inner wall of the second mounting cavity 42.
[0044] Specifically, for example Figure 5 or Figure 12As shown, the second sub-pressure regulating channel 45 connects the first mounting cavity 41 and the second mounting cavity 42. The second sub-pressure regulating channel 45 has a third sub-opening 451 and a fourth sub-opening 452. The third sub-opening 451 is disposed through the inner wall of the corresponding first mounting cavity 41, and the fourth sub-opening 452 is disposed through the inner wall of the corresponding second mounting cavity 42. Along the fluid flow path in the pressure regulating channel 43, the first sub-opening 441 is closer to the second throttling outlet 302 than the third sub-opening 451. When the difference between the fluid pressure on the second throttling inlet 301 side and the fluid pressure on the first relay outlet side reaches a certain value, the fluid enters the second sub-throttling channel 304 through the second throttling inlet 301 and reaches the first mounting cavity 41. It then enters the second sub-pressure regulating channel 45 from the first mounting cavity 41 through the third sub-opening 451, then enters the first sub-pressure regulating channel 44 through the pressure regulating valve 40, enters the first sub-throttling channel 303 from the first sub-pressure regulating channel 44 through the first sub-opening 441, and then flows out from the second throttling outlet 302.
[0045] In other embodiments, the second sub-pressure regulating channel 45 connects the second sub-throttling channel 304 and the second mounting cavity 42, and correspondingly, the third sub-opening 451 is disposed through the inner wall of the second sub-throttling channel 304.
[0046] In some embodiments, the mounting base 4 has a first channel 401, which at least partially forms a first sub-pressure regulating channel 44. The mounting base 4 includes a first sub-throttling section 47, which includes a first sub-throttling channel 303 and a corresponding inner wall. The first channel 401 is machined and extends through the first sub-throttling section 47 along the direction of the first straight line L1. The first channel 401 has a first opening 4021, which is the machined inlet of the first channel 401. The mounting base 4 has a first connecting surface 46, and a second outer surface 400 includes the first connecting surface 46. The first opening 4021 is disposed through the first connecting surface 46. The heat exchanger 2 has a second connecting surface 23, which is included on the outer surface of the heat exchanger 2. The first connecting surface 46 and the second connecting surface 23 are sealed together, and the second connecting surface 23 blocks the first opening 4021.
[0047] Specifically, for example Figure 4 or Figure 11As shown, the first channel 401 includes the first sub-pressure regulating channel 44 and the first processing channel 402. The first processing channel 402 includes a first opening 4021 and a third opening 4022, with the third opening 4022 penetrating through the inner wall corresponding to the first sub-throttling channel 303. When the first sub-pressure regulating channel 44 is formed in the mounting base 4, the tool first forms the first processing channel 402 in the mounting base 4, and then penetrates the first sub-throttling section 47 to form the first sub-pressure regulating channel 44. That is, the first sub-pressure regulating channel 44 is machined, and in order to form the first sub-pressure regulating channel 44, the first processing channel 402 is inevitably formed on the mounting base 4. To reduce fluid leakage, the first opening 4021 needs to be sealed. In related technologies, since the heat exchange component 100 and the throttling component are set independently, a customized plug is inserted into the first processing channel 402, and then the plug is sealed to the mounting base 4 to seal the first opening 4021. This makes the manufacturing process of the throttling component complex. In this application, the second throttling component 3 is installed on the heat exchanger 2, and the second connecting surface 23 of the heat exchanger 2 is sealed to the first connecting surface 46 where the first opening 4021 is located, thereby achieving the sealing of the first opening 4021 by the second connecting surface 23. This reduces the steps of customizing the plug and inserting it into the first opening 4021, simplifying the manufacturing process of the thermal management component 1000, which not only improves production efficiency but also reduces production costs.
[0048] Specifically, the mounting base 4 includes a first opening, which includes a first opening 4021 and a corresponding inner wall. Along the direction perpendicular to the second connecting surface 23, the orthographic projection of the first opening onto the second connecting surface 23 is located within the outer contour of the second connecting surface 23.
[0049] In some embodiments, the mounting base 4 has a second channel 404, which at least partially forms a second sub-pressure regulating channel 45. The mounting base 4 includes a first mounting portion 49 and a second sub-throttling portion 48. The first mounting portion 49 includes a first mounting cavity 41 and a corresponding inner wall of the first mounting cavity 41. The second sub-throttling portion 48 includes a second sub-throttling channel 304 and a corresponding inner wall of the second sub-throttling channel 304. The second channel 404 is machined and penetrates the first mounting portion 49 or the second sub-throttling portion 48 along the direction of the second straight line L2. The second channel 404 has a second opening 4031, which is the machined entrance of the second channel 404. The second opening 4031 is disposed through the first connecting surface 46; the second connecting surface 23 blocks the second opening 4031.
[0050] Specifically, for example Figure 4 or Figure 11As shown, the second channel 404 includes the second sub-pressure regulating channel 45 and the second processing channel 403. The second processing channel 403 includes a second opening 4031 and a fourth opening 4032, with the fourth opening 4032 penetrating through the inner wall of the first mounting cavity 41 or the corresponding second sub-throttling channel 304. When forming the second sub-pressure regulating channel 45 within the mounting base 4, the tool first forms the second processing channel 403 on the mounting base 4, and then penetrates the first sub-throttling portion 47 or the first mounting portion 49 to form the second sub-pressure regulating channel 45. In other words, the second sub-pressure regulating channel 45 is machined, and the second processing channel 403 is inevitably formed on the mounting base 4 in order to form the second sub-pressure regulating channel 45. To reduce fluid leakage, the fourth opening 4032 needs to be sealed. In related technologies, since the heat exchange component 100 and the throttling component are independently configured, a custom-made plug is inserted into the second processing channel 403, and then the plug is sealed to the mounting base 4 to achieve the sealing of the fourth opening 4032. This makes the manufacturing process of the throttling component complex. In this application, the second throttling component 3 is installed on the heat exchanger 2, and the second connecting surface 23 of the heat exchanger 2 is sealed to the first connecting surface 46 where the fourth opening 4032 is located, thereby achieving the sealing of the fourth opening 4032 by the second connecting surface 23. In this way, similar to the sealing of the first opening 4021 by the second connecting surface 23, the steps of customizing the plug and inserting it into the fourth opening 4032 can be reduced, simplifying the manufacturing process of the thermal management component 1000, which not only helps to improve production efficiency but also reduces production costs.
[0051] Specifically, the mounting base 4 includes a second opening, which includes a second opening 4031 and an inner wall corresponding to the second opening 4031. Along the direction perpendicular to the second connecting surface 23, the orthographic projection of the second opening onto the second connecting surface 23 is located within the outer contour of the second connecting surface 23.
[0052] In some implementations, for example, combined Figure 2 and Figure 5 or combination Figure 11 and Figure 14 As shown, the direction of the first straight line L1 is parallel to the direction of the second straight line L2, and the direction of the first straight line L1 is perpendicular to the plane containing the first connecting surface 46. This facilitates the processing of the first channel 401 and the second channel 404, which is beneficial to improving production efficiency.
[0053] In some embodiments, the mounting base 4 has a third channel 405, which is partially used to form a second mounting cavity 42 and partially used to form a first sub-voltage regulating channel 44 or a second sub-voltage regulating channel 45. The first channel 401 and the second channel 404 are both connected to the third channel 405, which extends along the direction of a third straight line L3. The directions of the first straight line L1 and the second straight line L2 both intersect the direction of the third straight line L3.
[0054] In the specific production process, the second mounting cavity 42 and the third channel 405 can be formed by machining along the direction of the third straight line L3. The second mounting cavity 42 is connected to the second channel 404, and the third channel 405 is connected to the first channel 401.
[0055] In some embodiments, the first straight line L1, the second straight line L2, and the third straight line L3 lie in the same plane, for example... Figure 5 or Figure 11 As shown.
[0056] In some embodiments, along a straight line perpendicular to the first connecting surface 46, the orthographic projection of the first connecting surface 46 onto the second connecting surface 23 lies within the outer contour of the second connecting surface 23; along a direction perpendicular to the first connecting surface 46, the pressure regulating valve 40 is farther away from the heat exchanger 2 relative to the second expansion valve 31; or, the distance between the second expansion valve 31 and the heat exchanger 2 is a first distance, and the distance between the pressure regulating valve 40 and the heat exchanger 2 is a second distance, the first distance being equal to the second distance.
[0057] The thermal management component 1000 provided in this application includes a heat exchange component 100, wherein the heat exchange component 100 includes a first throttling component 1 and a heat exchanger 2. The heat exchange component 100 has a first flow channel 71 and a second flow channel 72. A first expansion valve 11 is at least partially located in the first flow channel 71, and the first expansion valve 11 is capable of throttling the fluid flowing through the first flow channel 71. A portion of the fluid flowing into the heat exchange component 100 flows into the first flow channel 71, and another portion flows into the second flow channel 72. After being throttled by the first expansion valve 11, the fluid flowing into the first flow channel 71 exchanges heat with the fluid in the second flow channel 72 in the heat exchanger 2, for example... Figure 23 As shown. In this application, the first flow channel 71 includes a first throttling channel 10 and a first fluid channel 21, and the second flow channel 72 includes a second fluid channel 22.
[0058] The first throttling assembly 1 includes a first expansion valve 11. The first throttling assembly 1 has a first throttling channel 10, with the first expansion valve 11 at least partially located within the first throttling channel 10. The first expansion valve 11 is capable of throttling the fluid flowing through the first throttling channel 10. The first throttling channel 10 has a first throttling orifice and a second throttling orifice, one of which is the inlet of the first throttling channel 10, and the other is the outlet of the first throttling channel 10. That is, it is not limited which of the first throttling orifice and the second throttling orifice is the inlet of the fluid before throttling, or which is the outlet of the fluid after throttling. For example, in some modes, fluid flows into the first throttling channel 10 from the first throttling orifice, is throttled by the first expansion valve 11, and then flows out from the second throttling orifice. The fluid flowing out from the second throttling orifice flows into the first fluid channel 21, where it exchanges heat with the fluid in the second fluid channel 22. That is, the first throttling orifice acts as the first throttling inlet 101, and the second throttling orifice acts as the first throttling outlet 102. In other modes, the fluid flowing out from the first fluid channel 21 flows into the first throttling channel 10 through the second throttling orifice. When it passes through the first expansion valve 11, the first expansion valve 11 does not have a throttling effect, and the first throttling channel 10 only acts as a flow path. After that, the fluid flows out of the first throttling channel 10 from the first throttling orifice.
[0059] The heat exchange components of the related technology are relatively heavy, and there is a need for lightweight improvement.
[0060] The inventors discovered that in related technologies, the heat exchange component 100 is relatively heavy because the connecting block 5 used to mount the expansion valve is large. For example, the connecting block 5 in related technologies... Figure 1 As shown, the connecting block 5 includes a first connecting block 51 and a second connecting block 52 connected to each other. The expansion valve has a first valve port 111 and a second valve port 112. The first connecting block 51 is provided with a first connecting channel 61, which communicates with the first valve port 111. The second connecting block 52 is provided with a second connecting channel 62, which communicates with the second valve port 112. The expansion valve is installed on the second connecting block 52. In some modes, after the fluid flows into the first connecting block 511 from the fluid inlet 60, part of it enters the second fluid channel 22 of the heat exchanger 2, and the other part enters the first valve port 111 of the expansion valve through the first connecting channel 61. After being throttled by the expansion valve, it flows out from the second valve port 112 to the second connecting channel 62, and then enters the first fluid channel 21 from the second connecting channel 62. The fluid in the first fluid channel 21 and the fluid in the second fluid channel 22 exchange heat in the heat exchanger 2. In related technologies, the first connecting block 51 and the second connecting block 52 are arranged side by side and at the same height, resulting in a large volume of the connecting block 5. The technical solution of this application improves the connecting block 5, reduces the volume of the connecting block 5, and thus reduces the weight of the heat exchange component 100.
[0061] The heat exchange assembly 100 provided in this application includes a heat exchanger 2 and a first throttling assembly 1. The first throttling assembly 1 includes a first expansion valve 11 and a connecting block 5. The connecting block 5 includes a first connecting block 51 and a second connecting block 52. The first expansion valve 11 is installed on the second connecting block 52. The heat exchanger 2 and the second connecting block 52 are both fixedly connected to the first connecting block 51. The heat exchange assembly 100 has a fluid inlet 60, a first connecting channel 61 and a second connecting channel 62. The first connecting channel 61 is at least partially disposed on the first connecting block 51, and the second connecting channel 62 is at least partially disposed on the second connecting block 52. The first expansion valve 11 has a first valve port 111 and a second valve port 112. The heat exchanger 2 has a first fluid channel 21 and a second fluid channel 22. The fluid inlet 60, the first valve port 111 and the second fluid channel 22 are all connected to the first connecting channel 61, and the second valve port 112 and the first fluid channel 21 are both connected to the second connecting channel 62. The first connecting block 51 includes a first connecting portion 511, and a first connecting channel 61 is partially disposed in the first connecting portion 511. Along the height direction of the heat exchanger 2, the first connecting portion 511 is located between the second connecting block 52 and the heat exchanger 2. The height of the first connecting portion 511 is H1, and the height of the second connecting block 52 is H2, where H1 < H2. For example... Figures 9 to 22 As shown.
[0062] In the heat exchange assembly 100 provided in this application, along the height direction H of the heat exchange assembly 100, the first connecting portion 511 is located between the second connecting block 52 and the heat exchanger 2, and the height H1 of the first connecting portion 511 is less than the height H2 of the second connecting block 52. Thus, the volume of the first connecting block 51 of the heat exchange assembly 100 can be reduced compared to related technologies, thereby reducing the weight of the connecting block 5 compared to related technologies, which is beneficial for reducing the weight of the heat exchange assembly 100. The first throttling channel 10 mentioned above includes a first connecting channel 61 and a second connecting channel 62.
[0063] Specifically, in combination Figures 15-17 or combination Figures 18-22As shown, in related technologies, the first expansion valve 11 has a certain width. The width direction of the first expansion valve 11, the height direction H of the heat exchange assembly 100, and the height direction of the connecting block 5 are parallel. Therefore, along the height direction of the connecting block 5, the second connecting block 52 used to install the first expansion valve 11 needs to have corresponding dimensions, making it difficult to reduce the height of the second connecting block 52. The internal flow channel of the first connecting block 51 is mainly used to connect the first valve port 111 of the first expansion valve 11 and the fluid inlet 60 of the heat exchange assembly 100, so that a portion of the fluid entering the heat exchange assembly 100 from the fluid inlet 60 can reach the first valve port 111 through the first connecting channel 61 provided in the first connecting block 51. This application reduces the volume of the first connecting block 51 by reducing the height of the first connecting portion 511 included in the first connecting block 51, thereby reducing the volume and weight of the connecting block 5.
[0064] Furthermore, in some implementations, for example Figure 9 or Figure 18 As shown, along the height direction H of the heat exchange assembly 100, the first connecting block 51 is located between the second connecting block 52 and the heat exchanger 2, and the height of the first connecting block 51 is H1. That is, compared to related technologies, this application reduces the overall height of the first connecting block 51, placing it between the second connecting block 52 and the heat exchanger 2, which helps to further reduce the weight of the heat exchange assembly 100. For example... Figure 9 and Figure 19 As shown, the first connecting block 51 is a plate-shaped component, and the second connecting block 52 is a block-shaped component.
[0065] In related technologies, the heat exchange component 100 has a width direction K, and the width direction K of the heat exchange component 100 is perpendicular to its height direction H, for example... Figure 9As shown. Along the width direction of the heat exchange assembly 100, the first valve port 111 is located on one side of the first expansion valve 11; along the length direction of the heat exchange assembly 100, the second valve port 112 is located on one side of the first expansion valve 11. Related art: To reduce the flow resistance of the first connecting channel 61, along the height direction H of the heat exchange assembly 100, the first connecting block 51 and the second connecting block 52 of the connecting block 5 are arranged side-by-side at the same height, and the first connecting channel 61 disposed in the first connecting block 51 and the second connecting channel 62 disposed in the second connecting block 52 are also arranged at the same height. In this application, to reduce the weight of the connecting block 5, the first connecting block 51 is at least partially disposed between the second connecting block 52 and the heat exchanger 2. To reduce the flow resistance of the first connecting channel 61 in this application while reducing the weight of the connecting block 5, in some embodiments of this application, along the height direction H of the heat exchange assembly 100, the first valve port 111 is located on one side of the first expansion valve 11; the first connecting channel 61 includes a first sub-connecting channel 611, which is at least partially disposed within the first connecting block 51. The first sub-connection channel 611 is at least partially aligned with the first valve port 111, and the first sub-connection channel 611 is at least partially disposed within the first connection portion 511. The first sub-connection channel 611 communicates with the first valve port 111, and along the height direction H of the heat exchange assembly 100, the first valve port 111 is farther away from the heat exchanger 2 relative to the first sub-connection channel 611.
[0066] In some implementations, for example Figure 16 , Figure 17 and Figures 19-21 As shown, the first connecting channel 61 includes a second sub-connecting channel 612, which is at least partially disposed on the second connecting block 52. Both the first valve port 111 and the first sub-connecting channel 611 communicate with the second sub-connecting channel 612. Along the height direction H of the heat exchange assembly 100, the second sub-connecting channel 612 is at least partially located between the first valve port 111 and the first sub-connecting channel 611. That is, the first valve port 111 and the first sub-connecting channel 611 are connected through the second sub-connecting channel 612.
[0067] In some embodiments, a plane perpendicular to the height direction of the heat exchange assembly 100 is defined, a straight line within this plane is defined as a first extending line l1, and a straight line parallel to the height direction of the heat exchange assembly 100 is defined as a second extending line l2. The first extending line l1 and the second extending line l2 lie in the same plane. The first sub-connecting channel 611 extends at least partially along the direction of the first extending line l1, and the second sub-connecting channel 612 extends at least partially along the direction of the second extending line l2. For example, the first sub-connecting channel 611 extends along the direction of the first extending line l1, and the second sub-connecting channel 612 extends along the direction of the second extending line l2. Figure 19 As shown.
[0068] In some implementations, for example Figure 10 , Figure 17 , Figure 19 and Figure 20 As shown, the outer surface of the first connecting portion 511 includes a first mounting surface 513. The first connecting portion 511 has a first connecting port 515, which extends through the first mounting surface 513. The first connecting portion 511 includes a second mounting surface 514. Along the thickness direction of the first connecting portion 511, the first mounting surface 513 and the second mounting surface 514 are located on opposite sides of the first connecting portion 511. The thickness direction of the first connecting block 51 is in the same direction as the height direction H of the heat exchange assembly 100. The first connecting block 51 has a first groove 517, which is formed by recessing from the second mounting surface 514 into the interior of the first connecting block 51. The first groove 517 communicates with the first connecting port 515. The first groove 517 is at least partially used to form a first sub-connecting channel 611. For example... Figure 16 , Figure 17 and Figures 18-20 As shown, the second mounting surface 514 is fixedly and sealed to the outer surface of the heat exchanger 2. The groove wall of the first groove 517 and the outer surface of the heat exchanger 2 form a first sub-connection channel 611. The second fluid channel 22 penetrates the outer surface of the heat exchanger 2 and communicates with the first sub-connection channel 611. Of course, in some other embodiments, the first sub-connection channel 611 can be located within the first connecting block 51. That is, the first connecting block 51 forms the first sub-connection channel 611 independently, and the walls of the first sub-connection channel 611 belong to the first connecting block 51. The outer surface of the second connecting block 52 includes a third mounting surface 521, and a second sub-connecting channel 612 is disposed through the third mounting surface 521; along the height direction H of the heat exchange assembly 100, the second sub-connecting channel 612 and the first sub-connecting channel 611 are respectively located on both sides of the first connecting port 515; the first mounting surface 513 is fixedly connected to the third mounting surface 521, the first mounting surface 513 and the third mounting surface 521 are sealed together, and the first sub-connecting channel 611 communicates with the second sub-connecting channel 612.
[0069] In some embodiments, the second sub-connecting channel 612 has a first channel opening 613, which extends through the outer surface of the second connecting block 52. The second connecting block 52 has a first channel opening 523, which includes the first channel opening 613 and a corresponding inner wall. A plane perpendicular to the height direction of the heat exchange assembly 100 is defined as the projection plane. Along the height direction H of the heat exchange assembly 100, the orthographic projection of the first mounting surface 513 onto the projection plane is the first projection, and the orthographic projection of the first channel opening 523 onto the projection plane is the second projection. The second projection is located within the outer contour of the first projection.
[0070] In some embodiments, the second connecting block 52 includes a first protrusion 522 protruding from the third mounting surface 521, and a second sub-connecting channel 612 extending through the first protrusion 522. The first protrusion 522 is at least partially located at the first connecting opening 515. This increases the connection strength between the first connecting block 51 and the second connecting block 52. In some embodiments, the first protrusion 522 is fixedly connected to the inner wall corresponding to the first connecting opening 515, and the first protrusion 522 is sealed to the inner wall corresponding to the first connecting opening 515. In some embodiments, a first channel opening 613 is provided in the first protrusion 522, or in other words, the first protrusion 522 has the first channel opening 613.
[0071] After the fluid enters the heat exchange assembly 100 from the fluid inlet 60, part of it directly enters the second fluid channel 22, and the other part enters the first sub-connection channel 611, and then flows into the second sub-connection channel 612 to reach the first valve port 111.
[0072] In some embodiments, along the height direction H of the heat exchange assembly 100, the first connecting block 51 and the second connecting block 52 are located on the same side of the heat exchanger 2, for example... Figure 9 and Figure 19 As shown, this facilitates the combination of the first connecting block 51 and the second connecting block 52 to form corresponding flow channels. The second connecting block 52 is at least partially mounted on the first connecting portion 511, and along the height direction H of the heat exchange assembly 100, the second connecting block 52 is at least partially away from the heat exchanger 2 relative to the first connecting portion 511. As mentioned earlier, the third mounting surface 521 of the second connecting block 52, which has a second sub-connecting channel 612, is fixedly and sealingly connected to the first mounting surface 513 of the first connecting portion 511; that is, the portion of the second connecting block 52 with the second sub-connecting channel 612 is mounted on the first connecting portion 511. The second connecting channel 62 is at least partially located on the second connecting block 52, and this portion can be mounted on the first connecting block 51 or directly on the heat exchanger 2.
[0073] In one embodiment, the portion of the second connecting block 52 having the second connecting channel 62 can be mounted on the first connecting block 51. Specifically, the second connecting block 52 is mounted on the first connecting block 51. The first connecting portion 511 includes a first mounting surface 513, and the second connecting block 52 is mounted on the first mounting surface 513.
[0074] In some embodiments, the first connecting portion 511 has a second connecting port 516, which extends through the first mounting surface 513. The heat exchange assembly 100 has a third connecting channel 63, which is at least partially disposed in the first connecting portion 511. The third connecting channel 63 communicates with the second connecting port 516. For example... Figure 17 or Figure 20 As shown, the first connecting block 51 has a second groove 518, which is recessed from the second mounting surface 514 into the interior of the first connecting block 51. The second groove 518 communicates with the second connecting port 516. The second mounting surface 514 is fixedly and sealed to the outer surface of the heat exchanger 2. The groove wall of the second groove 518 and the outer surface of the heat exchanger 2 form a third connecting channel 63. In other embodiments, the third connecting channel 63 can be located within the first connecting block 51, meaning the first connecting block 51 alone forms the third connecting channel 63, and the inner wall of the third connecting channel 63 belongs to the first connecting block 51. The second connecting channel 62 and the second fluid channel 22 both communicate with the third connecting channel 63. Along the height direction H of the heat exchange assembly 100, the second connecting channel 62 is farther away from the second fluid channel 22 relative to the third connecting channel 63. In other words, the second connecting channel 62 communicates with the second fluid channel 22 through the third connecting channel 63.
[0075] The second connecting channel 62 penetrates the third mounting surface 521 and has a second channel opening 623, which penetrates the outer surface of the second connecting block 52. The second connecting block 52 has a second channel opening 524, which includes the second channel opening 623 and an inner wall corresponding to the second channel opening 623. A plane perpendicular to the height direction of the heat exchange assembly 100 is defined as the projection plane. Along the height direction H of the heat exchange assembly 100, the orthographic projection of the second channel opening 524 onto the projection plane is the third projection, which is located within the outer contour of the first projection. That is, both the second and third projections are located within the outer contour of the first projection.
[0076] In some embodiments, the second connection channel 62 includes a third sub-connection channel 621 and a fourth sub-connection channel 622, the third sub-connection channel 621 communicating with the fourth sub-connection channel 622. Along the length of the heat exchange assembly 100, the fourth sub-connection channel 622 is located away from the second valve port 112 relative to the third sub-connection channel 621; along the height direction H of the heat exchange assembly 100, the fourth sub-connection channel 622 is at least partially close to the heat exchanger 2 relative to the third sub-connection channel 621. The fourth sub-connection channel 622 has the second channel opening 623.
[0077] In some embodiments, the second connecting block 52 includes a second protrusion 525 that protrudes from the third mounting surface 521, and a second connecting channel 62 extends through the second protrusion 525, for example... Figure 16 or Figure 21 As shown, a fourth sub-connecting channel 622 extends through the second protrusion 525, which has a second channel opening 623. The second protrusion 525 is at least partially located at the second connecting port 516. This increases the connection strength between the first connecting block 51 and the second connecting block 52. In some embodiments, the second protrusion 525 is fixedly connected to the inner wall corresponding to the second connecting port 516, and the second protrusion 525 is sealed to the inner wall corresponding to the second connecting port 516.
[0078] In another embodiment, the portion of the second connecting block 52 having the second sub-connecting channel 612 is directly installed on the heat exchanger 2. A portion of the second connecting block 52 is installed on the first connecting block 51, and a portion of the second connecting block 52 is installed on the heat exchanger 2.
[0079] The outer surface of the second connecting block 52 includes a fourth mounting surface (not shown), and the second connecting channel 62 is disposed through the fourth mounting surface. The second connecting channel 62 has a second channel opening 623, which is disposed through the outer surface of the second connecting block 52. The second connecting block 52 has a second channel opening portion 524, which includes an inner wall corresponding to the second channel opening 623. The outer surface of the heat exchanger 2 includes a first sub-mounting surface and a second sub-mounting surface. The second mounting surface 514 is fixedly connected and sealed to the first sub-mounting surface, and the fourth mounting surface is fixedly connected and sealed to the second sub-mounting surface. A plane perpendicular to the height direction of the heat exchange assembly 100 is defined as a projection plane. Along the height direction H of the heat exchange assembly 100, the orthographic projection of the second channel opening portion 524 onto the projection plane is a third projection, and the orthographic projection of the second sub-mounting surface onto the projection plane is a fourth projection. The third projection is located within the outer contour of the fourth projection. The second connecting channel 62 is directly connected to the second fluid channel 22.
[0080] In some embodiments, the heat exchanger 2 is a plate heat exchanger, which includes a plurality of plates 24 stacked along the height direction of the plate heat exchanger. The plate heat exchanger has a first inter-plate channel 211 and a second inter-plate channel 212, the first fluid channel 21 including the first inter-plate channel 211, and the second fluid channel 22 including the second inter-plate channel 212. Along the height direction of the plate heat exchanger, the first throttling assembly 1 and the second throttling assembly are located on the same side of the plate heat exchanger, for example... Figure 9 and Figure 19 As shown, or, the first throttling component 1 and the second throttling component 3 are located on both sides of the plate heat exchanger, respectively.
[0081] Furthermore, the plate heat exchanger has a first distribution channel 213, a second distribution channel 214, at least two first inter-plate channels 211, and at least two second inter-plate channels 212. The at least two first inter-plate channels 211 are all connected to the first distribution channel 213, and the at least two second inter-plate channels 212 are all connected to the second distribution channel 214. The first fluid channel 21 includes the first distribution channel 213 and the at least two first inter-plate channels 211, and the second fluid channel 22 includes the second distribution channel 214 and the at least two second inter-plate channels 212. The height direction of the plate heat exchanger is the same as the height direction H of the heat exchange assembly 100.
[0082] The first fluid passage 21 has a first flow channel opening 215 and a third flow channel opening 217, one of which is the inlet of the first fluid passage 21, and the other is the outlet of the first fluid passage 21. Along the height direction of the plate heat exchanger, the first flow channel opening 215 and the third flow channel opening 217 are located on opposite sides of the plate heat exchanger, or they are located on the same side of the plate heat exchanger. The first distribution passage 213 includes the first flow channel opening 215.
[0083] The second fluid passage 22 has a second flow channel opening 216 and a fourth flow channel opening 218, one of which is the inlet of the second fluid passage 22, and the other is the outlet of the second fluid passage 22. Along the height direction of the plate heat exchanger, the second flow channel opening 216 and the fourth flow channel opening 218 are located on opposite sides of the plate heat exchanger, or they are located on the same side of the plate heat exchanger. The second distribution passage 214 includes the second flow channel opening 216.
[0084] In some embodiments, along the height direction of the plate heat exchanger, the first flow channel opening 215 and the second flow channel opening 216 are located on the same side of the plate heat exchanger, or the first flow channel opening 215 and the second flow channel opening 216 are located on opposite sides of the plate heat exchanger.
[0085] In subcooling mode, the first expansion valve 11 is in operation, and it can throttle the fluid flowing into the first valve port 111. The throttled fluid then flows out from the second valve port 112. In subcooling mode, the first flow channel opening 215 is the inlet of the first fluid channel 21, and the third flow channel opening 217 is the outlet of the first fluid channel 21; the second flow channel opening 216 is the inlet of the second fluid channel 22, and the fourth flow channel opening 218 is the outlet of the second fluid channel 22.
[0086] In some embodiments, the heat exchange assembly 100 includes a connecting pipe 600, and a fluid inlet 60 is disposed in the connecting pipe 600.
[0087] In one embodiment, along the width direction K of the heat exchange assembly 100, the first flow channel opening 215 and the third flow channel opening 217 are located at the same end of the plate heat exchanger, and the second flow channel opening 216 and the fourth flow channel opening 218 are located at the same end of the plate heat exchanger, for example... Figure 19 and Figure 20 As shown. Along the length direction C of the heat exchange assembly 100, the first flow channel opening 215 and the third flow channel opening 217 are located at both ends of the plate heat exchanger, respectively, and the second flow channel opening 216 and the fourth flow channel opening 218 are located at both ends of the plate heat exchanger, respectively.
[0088] Specifically, along the width direction K of the heat exchange assembly 100, the first flow channel opening 215 and the second flow channel opening 216 are located at both ends of the plate heat exchanger, respectively; along the length direction C of the heat exchange assembly 100, the first flow channel opening 215 and the second flow channel opening 216 are located at both ends of the plate heat exchanger, respectively. That is, the first flow channel opening 215 and the second flow channel opening 216 are arranged diagonally. Similarly, the third flow channel opening 217 and the fourth flow channel opening 218 are arranged diagonally.
[0089] In some embodiments, along the height direction H of the heat exchange assembly 100, the connecting pipe 600 is at least partially located on the same side of the heat exchanger 2 as the first connecting block 51. The connecting pipe 600 is mounted on the first connecting block 51, and the fluid inlet 60, the first connecting channel 61, and the first flow channel opening 215 are located on the same side of the heat exchanger 2. Specifically, the first connecting block 51 has a first surface and a second surface, which are located on opposite sides of the first connecting block 51 along the height direction H of the heat exchange assembly 100. The first surface includes the first mounting surface 513 described above, and the second surface includes the second mounting surface 514 described above. The first connecting block 51 has a third connecting port that extends through the first surface; the first connecting block 51 also has a groove, including the first groove 517 and the second groove 518 described above, which are formed by recessing from the first surface into the interior of the first connecting block 51. The second surface is fixedly and sealed to the outer surface of the heat exchanger 2. Along the height direction H of the heat exchange assembly 100, the fluid inlet 60 and the first connecting channel 61 are located on the same side of the heat exchanger 2, with the fluid inlet 60 being farther away from the second fluid channel 22 relative to the first connecting channel 61. Both the fluid inlet 60 and the first flow channel opening 215 are in communication with the first connecting channel 61.
[0090] Thus, the fluid flowing in from the fluid inlet 60 first enters the first connecting channel 61, and then is divided into two parts within the first connecting channel 61. One part enters the first distribution channel 213 from the first flow channel opening 215, and is then distributed from the first distribution channel 213 to at least two first inter-plate channels 211, and then flows out of the plate heat exchanger from the third flow channel opening 217. The other part reaches the first valve port 111 through the first connecting channel 61, and after being throttled by the first expansion valve 11, flows out from the second valve port 112, enters the second flow channel opening 216 through the second connecting channel 62, then flows into the second distribution channel 214, and is then distributed with the second distribution channel 214 to at least two second inter-plate channels 212, and then flows out of the plate heat exchanger from the fourth flow channel opening 218.
[0091] In some embodiments, the fluid inlet 60 is coaxially arranged with the first flow channel opening 215. Further, in some embodiments, the fluid inlet 60 is coaxially arranged with the first distribution flow channel 213. In some embodiments, the fluid inlet 60 and the first flow channel opening 215 have the same shape and flow area.
[0092] In another embodiment, along the width direction K of the heat exchange assembly 100, the first flow channel opening 215 and the third flow channel opening 217 are located at both ends of the plate heat exchanger, and the second flow channel opening 216 and the fourth flow channel opening 218 are located at both ends of the plate heat exchanger; along the length direction C of the heat exchange assembly 100, the first flow channel opening 215 and the third flow channel opening 217 are located at both ends of the plate heat exchanger, and the second flow channel opening 216 and the fourth flow channel opening 218 are located at both ends of the plate heat exchanger, that is, the first flow channel opening 215 and the third flow channel opening 217 are diagonally arranged, and the second flow channel opening 216 and the fourth flow channel opening 218 are diagonally arranged, for example... Figure 16 and Figure 17 As shown.
[0093] In some implementations, for example Figure 16 As shown, along the height direction H of the heat exchange assembly 100, the connecting pipe 600 and the first connecting block 51 are located on opposite sides of the heat exchanger 2, respectively, and the fluid inlet 60 is located away from the first connecting channel 61 relative to the second fluid channel 22. The first connecting channel 61 and the fluid inlet 60 are located on opposite sides of the first distribution channel 213. For example... Figure 16 As shown, the heat exchange assembly 100 includes a third connecting block 53, which is fixedly connected to the heat exchanger 2. The connecting pipe 600 is fixedly connected to the heat exchanger 2 via the third connecting block 53. Along the height direction H of the heat exchange assembly 100, the first flow channel opening 215 and the third flow channel opening 217 are located on the same side of the heat exchanger 2, and the second flow channel opening 216 and the fourth flow channel opening 218 are located on opposite sides of the heat exchanger 2.
[0094] Thus, the fluid flows from the fluid inlet 60 to the first flow channel opening 215, enters the first distribution flow channel 213, and a portion of the fluid is distributed from the first distribution flow channel 213 to at least two first inter-plate channels 211. After heat exchange, it flows out from the third flow channel opening 217. Another portion of the fluid flows from the first distribution flow channel 213 to the first connecting channel 61, from the first connecting channel 61 to the first valve port 111, and after being throttled by the first expansion valve 11, it flows from the second valve port 112 to the second connecting channel 62. Then, it enters the second distribution flow channel 214 through the second flow channel opening 216, and from the second distribution flow channel 214, it is distributed to at least two second inter-plate channels 212. After heat exchange, it flows out from the fourth flow channel opening 218.
[0095] In some embodiments, the fluid inlet 60 and the first flow channel opening 215 are coaxially arranged, or the fluid inlet 60 is coaxially arranged with the first distribution flow channel 213.
[0096] In some embodiments, the second channel opening 623 is at least partially aligned with the second flow channel opening 216. Further, a portion of the second connecting channel 62 is coaxially aligned with the second flow channel opening 216, or in other words, a portion of the second connecting channel 62 is coaxially aligned with the second distribution flow channel 214. For example, the second connecting channel 62 includes a third sub-connecting channel 621 and a fourth sub-connecting channel 622, the third sub-connecting channel 621 and the fourth sub-connecting channel 622 communicating with each other. The third sub-connecting channel 621 extends along a first direction, and the fourth sub-connecting channel 622 extends along a second direction. The first direction is perpendicular to the height direction H of the heat exchange assembly 100, and the second direction is parallel to the height direction H of the heat exchange assembly 100. The fourth sub-connecting channel 622 is coaxially aligned with the second distribution flow channel 214.
[0097] In some embodiments, the plate heat exchanger includes a body portion 25 and an edge portion 26, the body portion 25 being connected to the edge portion 26. Along the height direction of the plate heat exchanger, the edge portion 26 protrudes beyond the body portion 25. A first connecting block 51 is mounted on the body portion 25, and the edge portion 26 is located around the periphery of the first connecting block 51. Along the height direction of the plate heat exchanger, the edge portion 26 protrudes beyond the body portion 25 by a height h, where H1 ≤ h, for example... Figure 16 As shown, or H1 > h, for example Figure 21 As shown.
[0098] In some embodiments, the first connecting block 51 includes a second connecting portion 512, which is connected to the first connecting portion 511. A first connecting channel 61 is partially disposed in the second connecting portion 512. Specifically, a portion of the first sub-connecting channel 611 is disposed in the second connecting portion 512, and another portion of the first sub-connecting channel 611 is disposed in the first connecting portion 511. A third connecting port is disposed in the second connecting portion 512, and a connecting pipe 600 is installed in the second connecting portion 512. A plane perpendicular to the height direction of the heat exchange assembly 100 is defined as the projection plane. Along the height direction H of the heat exchange assembly 100, the orthographic projection of the second connecting portion 512 onto the projection plane is the first sub-projection, and the orthographic projection of the first connecting portion 511 onto the projection plane is the second sub-projection. The projection plane includes a first line l1' and a second line l2', both of which are straight lines. The first sub-projection extends along the direction of the first line l1', and the second sub-projection extends along the direction of the second line l2'. The first line l1' and the second line l2' intersect, for example... Figure 19 As shown; or, the first line l1' coincides with the second line l2', that is, the second connecting portion 512 and the first connecting portion 511 extend in the same direction, for example. Figure 10 As shown.
[0099] In some embodiments, along the length direction C of the heat exchange assembly 100, the distance D1 between the second flow channel opening 216 and the fourth flow channel opening 218, and the length of the second connecting block 52 are L, where L < D1. Thus, compared to related technologies, the size of the second connecting block 52 in the length direction C of the heat exchange assembly 100 is reduced, which is beneficial to reducing the volume of the second connecting block 52, thereby further reducing the weight of the heat exchange assembly 100.
[0100] In some embodiments, the heat exchange assembly 100 provided in the second aspect of this application is further equipped with a second throttling assembly 3. The second throttling assembly 3 includes a second expansion valve 31 and has a second throttling channel 30. The second expansion valve 31 is at least partially located in the second throttling channel 30 and can be used to throttle the fluid flowing through the second throttling channel 30. The second throttling channel 30 has a third throttling orifice and a fourth throttling orifice, one of which is the inlet of the second throttling channel 30, and the other of which is the outlet of the second throttling channel 30. That is, it is not limited which of the third throttling orifice and the fourth throttling orifice is the inlet of the fluid before throttling and which is the outlet of the fluid after throttling. The surface of the heat management assembly 1000 is a first outer surface 1001, and both the third throttling orifice and the fourth throttling orifice are disposed through the first outer surface 1001. For example, in some modes, the third orifice acts as the second orifice inlet 301 described above, and the fourth orifice acts as the second orifice outlet 302 described above, with fluid flowing in from the third orifice and out from the fourth orifice; in other modes, fluid flows in from the fourth orifice and out from the third orifice.
[0101] The first throttling component 1 and the second throttling component 3 are respectively installed in the heat exchanger 2; the heat exchanger 2 has a first fluid channel 21 and a second fluid channel 22, and one of the first throttling orifice and the second throttling orifice is directly connected to the first fluid channel 21. Alternatively, the first throttling component 1 included in the thermal management component 1000 provided in the first aspect of this application may have the same configuration as that in the second aspect of this application.
[0102] In some implementations, the thermal management components provided in this application are used in multi-split air conditioning systems.
