The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0027] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0028] Please see Figures 1 to 3This application provides a thermal management device 100, which includes a first support 1, a heat exchange assembly 2, a valve island assembly 3, and a flow channel assembly 4. The heat exchange assembly 2, the valve island assembly 3, and the flow channel assembly 4 are all disposed on the first support 1.

[0029] For the first support 1 mentioned above, please refer to Figure 2 and Figure 3 The first support 1 can be in the form of a thin plate. The heat exchange assembly 2, valve island assembly 3, and flow channel assembly 4 can be respectively arranged on opposite sides of the first support 1, thereby making the positional distribution of the heat exchange assembly 2, valve island assembly 3, and flow channel assembly 4 on the first support 1 more uniform, and the overall thermal management device 100 more compact and smaller in size. Optionally, the heat exchange assembly 2, valve island assembly 3, and flow channel assembly 4 are installed on the first support 1 by screws or bolts.

[0030] For the heat exchange component 2 mentioned above, please refer to Figure 2 and Figure 3 The heat exchange component 2 is used for multiple fluids to pass through and for heat transfer between these fluids. For example, the heat exchange component 2 has multiple channels that are isolated from each other. When fluids of different temperatures are introduced into two of the channels, the heat from the higher-temperature fluid is conducted through the wall of the heat exchange component 2 to the lower-temperature fluid, causing the temperature of the higher-temperature fluid to decrease and the temperature of the lower-temperature fluid to increase, thus achieving heat exchange. Optionally, the fluid is a refrigerant and / or a coolant.

[0031] In some embodiments, please refer to Figure 2 and Figure 3 The heat exchange assembly 2 includes a heat exchange plate 21 and a first connecting member 22. The first connecting member 22 communicates with the heat exchange plate 21 and is detachably connected to the valve island assembly 3. The first connecting member 22 is used to communicate with the valve island assembly 3 when connected to it. Exemplarily, the first connecting member 22 is welded to the heat exchange plate 21. When the heat exchange assembly 2 and the valve island assembly 3 are assembled, the first connecting member 22 abuts against an opening on the valve island assembly 3, thereby communicating between the heat exchange plate 21 and the valve island assembly 3, facilitating communication between them. The first connecting member 22 can be fixed to the valve island assembly 3 with screws.

[0032] In some embodiments, please refer to Figure 2 and Figure 3 The heat exchange assembly 2 includes a plurality of heat exchange plates 21 spaced apart. Optionally, the heat exchange assembly 2 includes two heat exchange plates 21.

[0033] For valve island assembly 3 mentioned above, please refer to Figure 3The valve island assembly 3 is connected to the heat exchange assembly 2. The valve island assembly 3 is connected to the heat exchange assembly 2 through multiple channels, which can control the flow of fluid into the heat exchange assembly 2 from different positions and control the flow of fluid out of the heat exchange assembly 2 from different positions. In this way, the flow channels and directions of the fluid in the heat exchange assembly 2 can be controlled to achieve heating or cooling of the target fluid.

[0034] Understandably, the valve island assembly 3 is also used to connect with the condenser, evaporator, heating element, etc., to dissipate heat outside the thermal management device 100 and to introduce additional heat into the thermal management device 100. Thus, when the fluid cannot reach the target temperature through internal heat exchange in the thermal management device 100, the fluid can dissipate heat to the outside or additional heat can be introduced into the fluid to allow the fluid to reach the target temperature.

[0035] In some embodiments, please refer to Figure 3 The valve island assembly 3 includes a second support 31, a first valve body 32, and a second valve body 33. The second support 31 is mounted on the first support 1, and the first valve body 32 and the second valve body 33 are mounted on the second support 31. Both the first valve body 32 and the second valve body 33 are connected to the heat exchange assembly 2. The first valve body 32 and the second valve body 33 are mounted on the first support 1 via the second support 31. Compared to the first valve body 32 and the second valve body 33 being mounted on the heat exchange assembly 2, this improves the thermal insulation between the first valve body 32 and the second valve body 33 and the heat exchange assembly 2.

[0036] In some embodiments, please refer to Figure 3 The first valve body 32 and the second valve body 33 are spaced apart. The first valve body 32 and the second valve body 33 can be used for the passage of high-temperature fluid and low-temperature fluid, respectively, thereby improving the thermal insulation of fluids from different paths within the valve island assembly 3.

[0037] For the specific structure of the first valve body 32, please refer to some embodiments. Figures 3 to 5 The first valve body 32 is provided with a first valve chamber 321, a second valve chamber 322, a first port 323 and a second port 324. The first valve chamber 321 is connected to the first port 323, and the second valve chamber 322 is connected to the heat exchange component 2. The first valve body 32 is provided with a first connecting channel 325 and two valve cores 34. The two valve cores 34 control the opening and closing of the first valve chamber 321 and the second valve chamber 322 respectively, so as to control the connection or disconnection of the first valve chamber 321 and the second valve chamber 322 with the first connecting channel 325.

[0038] When the second valve chamber 322 is closed, the first valve body 32 of the heat exchange assembly 2 is isolated; when both the first valve chamber 321 and the second valve chamber 322 are open, both the first port 323 and the second port 324 are connected to the heat exchange assembly 2; when the first valve chamber 321 is closed and the second valve chamber 322 is open, the second port 324 is connected to the heat exchange assembly 2.

[0039] For the specific structure of the second valve body 33, please refer to some embodiments. Figure 4 and Figure 5 The second valve body 33 is provided with a third valve chamber 331, a fourth valve chamber 332, a fifth valve chamber 333, a sixth valve chamber 334, a third port 335, a fourth port 336, and a fifth port 337. The third valve chamber 331 and the fourth valve chamber 332 are each connected to a heat exchange plate 21, while the fifth port 337, the fifth valve chamber 333, and the sixth valve chamber 334 are each connected to another heat exchange plate 21. The second valve body 33 is provided with a second connecting channel, a third connecting channel, and four valve cores 34. The four valve cores 34 respectively control the opening and closing of the third valve chamber 331, the fourth valve chamber 332, the fifth valve chamber 333, and the sixth valve chamber 334, thereby controlling the connection or disconnection between the third valve chamber 331 and the sixth valve chamber 334 and the third connecting channel, and controlling the connection or disconnection between the fourth valve chamber 332 and the fifth valve chamber 333 and the second connecting channel. The third port 335 is connected to the third connecting channel, and the fourth port 336 is connected to the second connecting channel.

[0040] When both the third valve chamber 331 and the sixth valve chamber 334 are closed, the third port 335 is isolated from both heat exchange plates 21; when one of the third valve chamber 331 and the sixth valve chamber 334 is open, the third port 335 is connected to one of the heat exchange plates 21; when both the third valve chamber 331 and the sixth valve chamber 334 are open, the third port 335 is connected to both heat exchange plates 21.

[0041] When both the fourth valve chamber 332 and the fifth valve chamber 333 are closed, the fourth port 336 is isolated from both heat exchange plates 21; when one of the fourth valve chamber 332 and the fifth valve chamber 333 is open, the fourth port 336 is connected to one of the heat exchange plates 21; when both the fourth valve chamber 332 and the fifth valve chamber 333 are open, the fourth port 336 is connected to both heat exchange plates 21.

[0042] For the flow channel component 4 mentioned above, please refer to Figures 1 to 3The flow channel assembly 4 includes a flow channel plate 41, a switching valve 42, and a liquid pump 43. The flow channel plate 41 is mounted on the first support 1 and has multiple fluid channels, at least two of which are connected to the heat exchange assembly 2. The switching valve 42 is mounted on the flow channel plate 41 and is connected to the multiple fluid channels. The switching valve 42 is used to control the connection or disconnection between the multiple fluid channels. The liquid pump 43 connects two fluid channels in series. It is understood that some channels are connected to vehicle interior components. By controlling the switching valve 42 and the liquid pump 43, the direction of fluid movement within the fluid channels can be controlled, for example, pumping fluid to or from the heat exchange assembly 2, pumping fluid to or from vehicle interior components, or drawing fluid from vehicle interior components. Specifically, drawing fluid from vehicle interior components can regulate the temperature of vehicle components, such as cooling the engine, transferring heat to or removing heat from the air conditioner, or regulating the battery temperature. Optionally, the switching valve 42 is a four-way valve.

[0043] In related technologies, the switching valve 42 and the liquid pump 43, as well as the switching valve 42, the liquid pump 43, and the heat exchange assembly 2 are all connected by pipes. However, in this embodiment, these pipes are integrated into the flow channel plate 41. That is, the fluid channels of the flow channel plate 41 replace some of the pipes, reducing the use of pipes and thus reducing the number and length of pipes. This improves the problem of the large space occupied by the thermal management device 100 and the problem of high heat loss. Furthermore, by using fluid channels instead of pipes, the switching valve 42 and the liquid pump 43 do not need to be connected to the flow channel plate 41. The flow channel plate 41 can be used to fix the switching valve 42 and the liquid pump 43, eliminating the need for additional fixing plates. This simplifies the assembly of the thermal management device 100 and improves its assembly efficiency. Moreover, the flow channel plate 41 has higher hardness and stronger corrosion resistance than pipes, which helps to improve the problem of high pressure loss in the thermal management device 100 and extends its service life.

[0044] For the specific structure of the flow channel assembly 4, please refer to some embodiments. Figure 6 and Figure 7The flow channel plate 41 is provided with fluid channels including a first flow channel 41a, a second flow channel 41b, a third flow channel 41c, a fourth flow channel 41d, a fifth flow channel 41e, a sixth flow channel 41f, and a seventh flow channel 41g. One end of each of the first, second, and third flow channels 41a, 41b, and 41c is connected to a first switching valve 42, and the third flow channel 41c is also connected to a second switching valve 42. The fourth, fifth, and sixth flow channels 41d, 41e, and 41f are all connected to the second switching valve 42. A first liquid pump 43 is connected in series between the sixth flow channel 41f and the seventh flow channel 41g. The first, second, and fifth flow channels 41a, 41b, 41e, and 41f are each provided with a port for connection to a pipe, while the fourth, 41d, and seventh flow channels 41g are respectively connected to two ports of the heat exchange assembly 2. The first switching valve 42 can control the on / off state of any two or three of the first flow channels 41a, the second flow channel 41b and the third flow channel 41c; the second switching valve 42 can control the on / off state of any two, three and four of the third flow channels 41c, the fourth flow channel 41d, the fifth flow channel 41e and the sixth flow channel 41f.

[0045] In some embodiments, please refer to Figure 6 and Figure 7 The flow channel plate 41 is provided with a fluid channel including an eighth flow channel 41h, which is connected to the heat exchange component 2 and to the third port of the heat exchange component 2. The eighth flow channel 41h is used to connect to a pipe, facilitating the connection between the pipe and the heat exchange component 2.

[0046] In some embodiments, please refer to Figure 6 and Figure 7 The flow channel plate 41 is provided with fluid channels including a ninth flow channel 41i, a tenth flow channel 41j, an eleventh flow channel 41k, a twelfth flow channel 41m, a thirteenth flow channel 41n, and a fourteenth flow channel 41o. One end of each of the ninth, tenth, eleventh, and twelfth flow channels 41i is connected to a third switching valve 42. A second liquid pump 43 is connected in series between the thirteenth flow channel 41n and the ninth flow channel 41i, and a third liquid pump 43 is connected in series between the fourteenth flow channel 41o and the eleventh flow channel 41k. The ninth, tenth, eleventh, eleventh, eleventh, twelfth, thirteenth, thirteenth, and fourteenth flow channels 41o are each provided with a port for connection to a pipe, and the tenth flow channel 41j is connected to the fourth port of the heat exchange component 2. The third switching valve 42 can control the on / off state of any two, three, or four of the ninth flow channel 41i, tenth flow channel 41j, eleventh flow channel 41k, and twelfth flow channel 41m.

[0047] In some embodiments, please refer to Figure 1The valve island assembly 3 and the heat exchange assembly 2 are located on opposite sides of the first support 1. Since the valve island assembly 3 and the heat exchange assembly 2 are directly connected, they are close to each other. By positioning the valve island assembly 3 and the heat exchange assembly 2 on opposite sides of the first support 1, the thickness of the thermal management device 100 is equal to the overall thickness of the valve island assembly 3 and the heat exchange assembly 2, thereby reducing the thickness of the thermal management device 100. Furthermore, this makes the weight distribution on both sides of the first support 1 more even.

[0048] In some embodiments, please refer to Figure 1 The flow channel assembly 4 and the valve island assembly 3 are located on the same side of the first support 1, with the flow channel assembly 4 surrounding the valve island assembly 3. That is, the flow channel assembly 4, the valve island assembly 3, and the heat exchange assembly 2 are distributed in a double layer, which helps to reduce the thickness of the thermal management device 100; and the heat exchange assembly 2 is connected to the flow channel assembly 4 and the valve island assembly 3 through one side, which facilitates the disassembly and assembly of the heat exchange assembly 2.

[0049] In some embodiments, please refer to Figure 3 The first bracket 1 has a first bend 11 at one end, with a first mounting hole 111 and a second mounting hole 112 at the first bend 111. The second bracket 31 has a second bend 311 at one end, with a third mounting hole 3111 and a fourth mounting hole 3112 at the second bend 311. The first mounting hole 111 and the third mounting hole 3111 are for the same fastener, and the second mounting hole 112 and the fourth mounting hole 3112 are for the same fastener. Thus, the first bracket 1 and the second bracket 31 are connected to each other at one end, which helps improve the thermal insulation between the valve island assembly 3 and the first bracket 1. The first bracket 1 and the second bracket 31 are connected by two fasteners, which increases the connection's strength compared to a single fastener connection and improves the problem of the second bracket 31 rotating relative to the first bracket 1. The first bracket 1 and the second bracket 31 are connected by the first bend 11 and the second bend 311, which helps to shorten the length of the first bracket 1 and the second bracket 31. Furthermore, the fasteners are installed facing inwards towards the thermal management device 100, making the thermal management device 100 more compact and shorter overall. Optionally, the bending angles of the first bend 11 and the second bend 311 are both right angles. Optionally, the fasteners are screws or bolts.

[0050] In some embodiments, please refer to Figure 3Both the first mounting hole 111 and the second mounting hole 112 are strip-shaped holes, and their extending directions are perpendicular to each other. Therefore, even with minor positional errors in the first and second mounting holes 111 and 112, or minor positional errors in the third and fourth mounting holes 3111 and 3112, the second bracket 31 can still be mounted on the first bracket 1, improving the tolerance of the second bracket 31 in mounting on the first bracket 1. The angle and position of the second bracket 31 relative to the first bracket 1 can also be adjusted by loosening the fasteners.

[0051] In some embodiments, please refer to Figure 2 and Figure 3 The first bracket 1 is provided with a first positioning hole 12, and the flow channel plate 41 is provided with a first positioning post 411, which passes through the first positioning hole 12. When assembling the first bracket 1 and the flow channel assembly 4, by having the first positioning post 411 pass through the first positioning hole 12, the relative positions of the flow channel assembly 4 and the first bracket 1 can be quickly positioned, improving assembly efficiency. Optionally, there are multiple first positioning holes 12 and first positioning posts 411, with each first positioning hole 12 and first positioning post 411 corresponding one-to-one, further improving the efficiency of the relative positioning between the flow channel assembly 4 and the first bracket 1.

[0052] In some embodiments, please refer to Figure 2 and Figure 3 The first bracket 1 is provided with a clearance opening 13, within which the heat exchange component 2 and the valve island component 3 are connected. The thermal management device 100 also includes a third bracket 5, which is disposed on the first bracket 1 and is at least partially located on the side of the heat exchange component 2 facing away from the first bracket 1. The clearance opening 13 facilitates the connection between the heat exchange component 2 and the valve island component 3 and the flow channel component 4. The connection between the heat exchange component 2 and the first bracket 1 via the third bracket 5 improves the thermal insulation between the heat exchange component 2 and the first bracket 1, thereby improving the thermal insulation between the heat exchange component 2 and the flow channel component 4 installed on the first bracket 1. Optionally, the third bracket 5 and the first bracket 1 are detachably connected by fasteners.

[0053] In some embodiments, please refer to Figure 2 and Figure 3 The heat exchange component 2 has a connecting post 23 on the side opposite to the first bracket 1, and the third bracket 5 has a fifth mounting hole 51 through which the connecting post 23 passes. Exemplarily, one end of the connecting post 23 is welded to the heat exchange plate 21, or it is integrally formed with the heat exchange plate 21. By having the connecting post 23 pass through the fifth mounting hole 51, the heat exchange component 2 can be installed on the third bracket 5, improving the problem of easy damage to the heat exchange component 2 and reduced fluid capacity caused by opening mounting holes in the heat exchange component 2. The connecting post 23 is used for threaded connection with a nut, thereby securely connecting the heat exchange component 2 to the third bracket 5.

[0054] In some embodiments, please refer to Figure 8 and Figure 9 The thermal management device 100 also includes a liquid storage tank 6, which is connected to the valve island assembly 3. The liquid storage tank 6 can balance the load in the fluid circuit, enhancing the operational stability of the thermal management device 100. Optionally, the liquid storage tank 6 has heat recovery characteristics, enabling it to transfer heat from the high-pressure liquid fluid to the low-pressure gaseous fluid, achieving heat energy recovery. Optionally, please refer to... Figure 9 The liquid storage tank 6 is connected to the first valve body 32 and the second valve body 33 respectively.

[0055] In some embodiments, please refer to Figure 8 and Figure 9 The third bracket 5 has a third bend 52, which bends in a direction away from the first bracket 1. The liquid storage tank 6 is detachably connected to the third bend 52. The outer diameter of the liquid storage tank 6 is relatively large. When the liquid storage tank 6 is directly installed on the third bracket 5, it cannot be installed on the side of the third bracket 5 facing the first bracket 1. Therefore, the liquid storage tank 6 can only be installed on the side of the third bracket 5 away from the first bracket 1, resulting in the liquid storage tank 6 protruding from the third bracket 5 by a distance equal to its outer diameter, and the thermal management device 100 having a relatively large thickness. In this embodiment, the third bend 52 bends in a direction away from the first bracket 1, so the liquid storage tank 6 can be installed on the side of the third bend 52 facing the first bracket 1. That is, the liquid storage tank 6 protrudes from the third bracket 5 along the side of the third bracket 5 facing the first bracket 1, reducing the distance the liquid storage tank 6 protrudes from the third bracket 5 and decreasing the thickness of the thermal management device 100. Furthermore, the liquid storage tank 6 is located between the third bend 52 and the first support 1, which can protect the liquid storage tank 6 and reduce the probability of damage to the liquid storage tank 6 when the thermal management device 100 is subjected to external pressure.

[0056] In some embodiments, please refer to Figure 8 The liquid storage tank 6 and the flow channel assembly 4 are respectively located on opposite sides of the first support 1. The flow channel assembly 4 has a large volume, especially in the length and width directions of the thermal management device 100. By distributing the liquid storage tank 6 and the flow channel assembly 4 in two layers, it is beneficial to reduce the length or width of the thermal management device 100.

[0057] In some embodiments, one end of the third bend 52 is connected to the liquid storage tank 6 by a fastener, and the other end of the third bend 52 is snap-fitted into the liquid storage tank 6. For example, please refer to... Figure 2 , Figure 3 and Figure 8The third bend 52 has a sixth mounting hole 521 at one end and a latch 522 at the other end. The storage tank 6 includes a tank body 61 and a collar 62. The collar 62 is detachably fitted onto the tank body 61, and the latch 522 is inserted into the gap between the collar 62 and the tank body 61. Alternatively, the collar 62 has a locking hole, and the latch 522 is inserted into the locking hole. One end of the tank body 61 has a threaded hole, and a fastener passes through the sixth mounting hole 521 and is threadedly connected to the tank body 61 through the threaded hole. The fastener connection and the locking connection are combined to facilitate the assembly and disassembly of the storage tank 6. Except for the part of the third bend 52 with the sixth mounting hole 521 that contacts the tank body 61, the other parts are spaced apart from the tank body 61, which helps to improve the thermal insulation between the tank body 61 and the third bend 52. Optionally, the collar 62 is made of a heat-insulating material, such as rubber.

[0058] In some embodiments, please refer to Figure 9 The storage tank 6 includes a tank body 61 and a second connecting member 63. The second connecting member 63 communicates with the tank body 61 and is detachably connected to the valve island assembly 3. The second connecting member 63 is used to communicate with the valve island assembly 3 when connected. Exemplarily, the second connecting member 63 is connected to the tank body 61 via a pipe. When the second connecting member 63 is assembled with the valve island assembly 3, it abuts against an opening on the valve island assembly 3, thereby connecting the tank body 61 and the valve island assembly 3, facilitating communication between the storage tank 6 and the valve island assembly 3. The second connecting member 63 can be fixed to the valve island assembly 3 with screws.

[0059] In some embodiments, please refer to Figure 9 The storage tank 6 includes a tank body 61 and a third connecting member 64. The third connecting member 64 is connected to the valve island assembly 3 and is detachably connected to the tank body 61. The third connecting member 64 is used to communicate with the tank body 61 when connected to it. Exemplarily, the third connecting member 64 is connected to the second connecting member 63 via a pipe, or the third connecting member 64 is directly connected to the valve island assembly 3 via a pipe. When the third connecting member 64 is assembled with the tank body 61, it abuts against an opening on the tank body 61, thereby connecting the tank body 61 to the valve island assembly 3, facilitating communication between the storage tank 6 and the valve island assembly 3. The third connecting member 64 can be fixed to the tank body 61 with screws.
