[0024] The present application will be further described below with reference to the accompanying drawings and specific embodiments:

[0025] See also Figure 1 , the thermal management component can be applied to a thermal management system, which can be a vehicle thermal management system, such as a new energy vehicle thermal management system. The thermal management component 100 includes a valve element, a throttling element, a heat exchange element and a connecting portion 10. The valve element, the throttling element and the heat exchange element are respectively fixedly connected or position-limited connected to the connecting portion 10, which can be specifically welded, bonded, threaded or plugged or screwed. In this embodiment, the valve element specifically includes a first valve element 21, a second valve element 22, and a third valve element 23, the throttling element specifically includes a first throttling element 31 and a second throttling element 32, and the heat exchange element specifically includes a first heat exchange element 41 and a second heat exchange element 42. Of course, as other embodiments, according to the actual application requirements of the thermal management system, the valve element, the throttling element and the heat exchange element can be other numbers respectively.

[0026] See also Figure 2The connecting portion 10 includes multiple mounting portions, each of which has a corresponding mounting cavity. The mounting cavity is used to accommodate at least part of the valve element and at least part of the throttling element. The valve element and the throttling element are connected to the connecting portion 10 through the mounting portions. In this embodiment, the connecting portion 10 has a first mounting cavity 101, a second mounting cavity 102, a third mounting cavity 103, a fourth mounting cavity 104, and a fifth mounting cavity 105. The openings of the mounting cavities are located on the same side of the connecting portion 10. Of course, in other embodiments, the openings of the mounting cavities can also be located on different sides of the connecting portion 10. The mounting cavity can be set near the edge of the connecting portion 10, and the mounting cavity can be arranged in sequence in a roughly linear manner. For example, in this example, the first mounting cavity 101, the second mounting cavity 102 and the third mounting cavity 103 are linearly arranged near one side edge of the connecting portion 10, the second mounting cavity 102 is located between the first mounting cavity 101 and the third mounting cavity 103, the third mounting cavity 103, the fourth mounting cavity 104 and the fifth mounting cavity 105 are linearly arranged near the other side edge of the connecting portion 10, and the fourth mounting cavity 104 is located between the third mounting cavity 103 and the fifth mounting cavity 105. The linear arrangement of the mounting cavities is beneficial to the neat layout of the valve element and the throttling element during installation, and can make full use of the space of the connecting portion 10, which is beneficial to making the structure of the thermal management component 100 compact.

[0027] See also Figure 2 The connecting portion 10 further includes a plurality of holes, each of which has a corresponding channel for communicating with the heat exchange element. In this embodiment, the channels specifically include a first channel 106, a second channel 107, a third channel 108, and a fourth channel 109. The openings of the channels and the opening of the mounting cavity are located on the same side of the connecting portion 10. In this embodiment, the connecting portion 10 also includes a hollow portion 20. The provision of the hollow portion 20 helps reduce the overall weight of the connecting portion 10, thereby reducing the overall weight of the thermal management assembly and reducing heat transfer in the connecting portion. Of course, if there is no specific weight requirement for the thermal management assembly, the connecting portion 10 may not include a hollow portion.

[0028] See also Figure 2 and Figure 3The connecting portion 10 has a plurality of ports, which are used to connect with other components of the thermal management system other than the thermal management components, such as the condenser, the outdoor heat exchanger, the battery cooling component, etc. In this embodiment, the ports specifically include a first port 111, a second port 112, a third port 113, a fourth port 114, and a fifth port 115. The ports can be located on different sides of the connecting portion 10 and are not located on the side where the opening of the installation cavity is located. Specifically, the first port 111 and the third port 113 are located on the same side of the connecting portion 10, the second port 112 and the fourth port 114 are located on the same other side of the connecting portion 10, and the fifth port 115 is located on another side of the connecting portion 10. The above three sides are different sides of the connecting portion 10, which is conducive to avoiding interference, improving the utilization rate of the connecting portion 10, and facilitating the connection of the thermal management component with other components of the thermal management system.

[0029] See also Figure 2 and Figure 3 The connecting portion 10 has a plurality of channels. In this embodiment, the channels specifically include a first channel 121, a second channel 122, a third channel 123, a fourth channel 124, a fifth channel 125, a sixth channel 126, and a seventh channel 127. Each channel extends to a certain length. As far as the connecting portion 10 is concerned, the first port 111 is connected to the first channel 121, the second port 112 is connected to the second channel 122, and the first channel 121 is connected to the second channel 122 through the third installation cavity 103; the third port 113 is connected to the third channel 123, and the third channel 123 is connected to the fourth installation cavity 103. The cavity 104 is connected to the first channel 121, and the third channel 123 is also connected to the sixth channel 126 through the fifth installation cavity 105, and the sixth channel 126 is connected to the second channel 107; the fourth port 114 is connected to the fourth channel 124, and the fourth channel 124 is connected to the first channel 121 through the second installation cavity 102, and the fourth channel 124 is also connected to the seventh channel 127 through the first installation cavity 101, and the seventh channel 127 is connected to the fourth channel 109; the fifth port 115 is connected to the fifth channel 125, and the fifth channel 125 is respectively connected to the first channel 106 and the third channel 108.

[0030] See also Figures 1 to 3, part of the first valve element 21 is located in the first installation cavity 101, part of the second valve element 22 is located in the second installation cavity 102, and part of the first throttling element 31 is located in the third installation cavity 103. The first valve element 21, the second valve element 22, and the first throttling element 31 are arranged in sequence near one side edge of the communicating portion 10, wherein the second valve element 22 is located between the first valve element 21 and the first throttling element 31, and the first throttling element 31 is arranged closer to the first port 111 than the first valve element 21; part of the third valve element 23 is located in the fourth installation cavity 104, and part of the second throttling element 32 is located in the fifth installation cavity 105. The first throttling element 31, the third valve element 23, and the second throttling element 32 are arranged in sequence near the other side edge of the communicating portion 10, the third valve element 23 is located between the first throttling element 31 and the second throttling element 32, and the first throttling element 31 is arranged closer to the first port 111 than the second throttling element 32. The valve element may be a solenoid valve or other forms of switch valves, and the throttling element may be an electronic expansion valve or other forms of throttling valves. The channels are connected or disconnected specifically through the valve element and / or the throttling element.

[0031] Each heat exchange element has a first flow channel and a second flow channel, the first flow channel and the second flow channel are not connected, and the working fluid in the first flow channel and the working fluid in the second flow channel can exchange heat in the heat exchange element. Figure 4 and Figure 5 , taking the first heat exchange element 41 as an example, in this embodiment, the first heat exchange element 41 includes a heat exchange portion 411 and a connecting plate 412, and the heat exchange portion 411 is fixedly connected to the connecting plate 412. Specifically, the heat exchange portion 411 and the connecting plate 412 can be fixed by welding. The first heat exchange element 41 has a first flow channel and a second flow channel (not shown in the figure). The flow channel used to communicate with the channel of the connecting portion 10 is defined as the first flow channel, and the flow channel connected to other components in the thermal management system (such as a vehicle battery cooling component, etc.) is defined as the second flow channel. The first flow channel has a first port 413 and a second port 414. The first port 413 and the second port 414 are located on the connecting plate 412. The first heat exchange element 41 is fixedly connected to the connecting portion 10 through the connecting plate 412. Specifically, see Figures 1 to 3In this embodiment, the connecting plate 412 and the connecting portion 10 are fixedly connected by screws. When the first heat exchange element 41 is fixedly connected to the connecting portion 10, the first port 413 and the first channel 106 can be aligned and connected to the first channel 106, and the second port 414 and the second channel 107 can be aligned and connected to the second channel 107. Furthermore, a seal is provided between the first port 413 and the first channel 106, and a seal is provided between the second port 414 and the second channel 107 to prevent fluid leakage from between the first port 413 and the first channel 106 and / or between the second port 414 and the second channel 107. Of course, in other embodiments, the connecting plate 412 and the connecting portion 10 can also be fixed by welding or gluing. The structure of the second heat exchange element 42 is the same as that of the first heat exchange element 41. Similarly, the second heat exchange element 42 is fixedly connected to the connecting portion 10 through its connecting plate, and the first port of its first flow channel is connected to the third channel 108, and the second port is connected to the fourth channel 109. The second flow channel of the second heat exchange element can be connected to other components in the thermal management system (such as transmission system cooling components, etc.).

[0032] See also Figures 1 to 7 In this embodiment, the thermal management component 100 includes at least two working modes:

[0033] First working mode: the first valve element 21, the third valve element 23, and the first throttling element 31 are closed, and the second valve element 22 and the second throttling element 32 are open. The first port 111 is connected to the first channel 121, and the second valve element 22 connects the first channel 121 and the fourth channel 124, and the fourth channel 124 is connected to the fourth port 114; the third port 113 is connected to the third channel 123, and the second throttling element 32 connects the third channel 123 and the sixth channel 126, and the sixth channel 126 is connected to the first flow channel of the first heat exchange element 41 through the second channel 107, and the first flow channel is connected to the fifth channel 125 through the first channel 106, and the fifth channel 125 is connected to the fifth port 115.

[0034] In this way, a working fluid (e.g., refrigerant) can flow from the first port 111 into the first channel 121, pass through the second valve element 22, and then flow out of the fourth port 114 through the fourth channel 124 to other components in the thermal management system. A working fluid flowing from the third port 113 into the third channel 123 is throttled by the second throttling element 32, then flows into the sixth channel 126, flows through the second channel 107 into the first flow channel of the first heat exchange element 41, flows through the first channel, then flows through the first channel 106 to the fifth channel 125, and flows out of the fifth port 115 to a subsequent circuit in the thermal management system. The working fluid (e.g., refrigerant) in the first flow channel of the first heat exchange element 41 can exchange heat with the working fluid (e.g., coolant) in the second flow channel of the first heat exchange element 41, thereby cooling a heat-generating component (e.g., a vehicle battery) in the thermal management system.

[0035] Second working mode: the second valve element 22 is closed, the first valve element 21, the third valve element 23, the first throttling element 31, and the second throttling element 32 are open, the first port 111 is connected to the first channel 121, the first throttling element 31 connects the first channel 121 with the second channel 122, and the second channel 122 is connected to the second port 112; the third port 113 is connected to the third channel 123, the third valve element 23 connects the first channel 121 with the third channel 123, the second throttling element 32 connects the third channel 123 with the sixth channel 126, and the sixth channel 127 is connected. 126 is connected to the first flow channel of the first heat exchange element 41 through the second channel 107, and the first flow channel of the first heat exchange element 41 is further connected to the fifth channel 125 through the first channel 106; the fourth port 114 is connected to the fourth channel 124, and the first valve element 21 connects the fourth channel 124 and the seventh channel 127, and the seventh channel 127 is connected to the first flow channel of the second heat exchange element 42 through the fourth channel 109, and the first flow channel of the second heat exchange element 42 is further connected to the fifth channel 125 through the third channel 108, and the fifth channel 125 is connected to the fifth port 115.

[0036] In this way, the working fluid can flow from the first port 111 into the first channel 121, and part of the working fluid in the first channel 121 flows to the second channel 122 after being throttled by the first throttling element 31, and flows out from the second port 112 to other components in the thermal management system; another part of the working fluid in the first channel 121 flows to the third channel 123 after passing through the third valve element 23, and part of the working fluid in the third channel 123 flows out from the third port 113 to other components of the thermal management system, and another part flows to the sixth channel 126 after being throttled by the second throttling element 32, and flows into the first through the second channel 107. The first flow channel of the heat exchange element 41 flows through the first flow channel of the first heat exchange element 41, and then flows to the fifth channel 125 through the first channel 106; the working fluid flowing into the fourth channel 124 from the fourth port 114 flows to the seventh channel 127 through the first valve element 21, and flows into the first flow channel of the second heat exchange element 42 through the fourth channel 109, flows through the first flow channel of the second heat exchange element 42, and then flows to the fifth channel 125 through the third channel 108. After mixing with the working fluid flowing from the first flow channel of the first heat exchange element 41 to the fifth channel 125, it flows out from the fifth port 115 and flows to the subsequent circuit in the thermal management system. The working fluid (e.g., refrigerant) in the first flow channel of the first heat exchange element 41 can exchange heat with the working fluid (e.g., coolant) in the second flow channel of the first heat exchange element 41. The working fluid (e.g., refrigerant) in the first flow channel of the second heat exchange element 42 can also exchange heat with the working fluid (e.g., coolant) in the second flow channel of the second heat exchange element 42, thereby cooling the heat-generating components in the thermal management system (e.g., vehicle batteries, transmission systems, etc.). It should be noted that heat-generating components are not limited to the vehicle batteries or transmission systems mentioned above, but can also be other components with heat generation.

[0037] See also Figure 8 and Figure 9, which is a second embodiment of the thermal management component.

The opening of the first mounting hole 131 and the opening of the second mounting hole 132 are located on the same side of the connecting portion 10' as the opening of the mounting cavity. With respect to the connecting portion 10' alone, the first mounting hole 131 is connected to the first channel 121, and the second mounting hole 132 is connected to the fourth channel 124. A portion of the first temperature sensor 51 is located in the first mounting hole 131, with at least the sensing portion of the first temperature sensor located in the first mounting hole 131 and / or in the first passage 121. A portion of the second temperature sensor 52 is located in the second mounting hole 132, with at least the sensing portion of the second temperature sensor located in the second mounting hole 132 and / or in the fourth passage 124. The first temperature sensor 51 and the second temperature sensor 52 are fixedly connected or position-limitedly connected to the connecting portion 10' via the mounting hole portions, specifically by welding, bonding, threaded connection, plug-in connection, or screw connection. In this embodiment, the first temperature sensor 51 is positioned near one side edge of the connecting portion 10' and is located between the first throttling element 31 and the third valve element 23. The second temperature sensor 52 is positioned near the other side edge of the connecting portion 10' and is located between the first valve element 21 and the second valve element 22. The first temperature sensor 51 is used to sense or measure the temperature of the working fluid in the first channel 121, and the second temperature sensor 52 is used to sense or measure the temperature of the working fluid in the fourth channel 124. By providing these temperature sensors, it is possible to determine whether the working fluid meets the subcooling requirements of the thermal management system in different operating modes, thereby providing feedback to the throttling element to adjust the valve opening. The remaining structure of the thermal management assembly 100' is not significantly different from that of the first embodiment and will not be further described here.

[0038] See also Figures 10 to 16, which is the third embodiment of the thermal management component. Compared with the second embodiment, in the third embodiment, the thermal management component 100" is further integrated with a gas-liquid separation component 61.

The connecting portion 141 has a sixth port 116, an eighth channel 128, a fifth hole 135, and a sixth hole 136. In this embodiment, the fifth channel 125" of the connecting portion 10" extends to the connecting portion 141. As far as the connecting portion 10" and the connecting portion 141 are concerned, the fifth channel 125" is also connected to the fifth hole 135, and the sixth port 116 is connected to the sixth hole 136 through the eighth channel 128. The gas-liquid separation component 61 is fixedly connected or limit-connected to the connecting part 141, which can be specifically welded, bonded, threaded, plugged, or screwed. In this embodiment, the gas-liquid separation component 61 is fixed to the connecting part 141 by screw connection. Specifically, the gas-liquid separation component 61 includes a fixing plate 611 and a connecting head 612. A threaded hole 133 is provided on the fixing plate 611, and a countersunk hole 134 is also provided on the connecting part 141. When the gas-liquid separation component 61 is connected to the connecting part 141, at least part of the connecting head 612 is located in the fifth channel 135, and the threaded hole 133 is aligned with the countersunk hole 134. A screw (not shown) passes through the countersunk hole 134 and is threadedly connected to the threaded hole 133, thereby realizing the connection and fixation of the gas-liquid separation component 61 and the connecting part 141. In this embodiment, the gas-liquid separation component 61 mainly performs gas-liquid two-phase separation of the working fluid. Specifically, the gas-liquid separation component 61 has an inlet 613 and an outlet 614, wherein the inlet 613 is the port of the connector 612, and the outlet 614 is located on the fixed plate 611. The inlet 613 and the outlet 614 are respectively connected to the inner cavity (not shown) of the gas-liquid separation component 61. The gas-liquid two-phase working fluid enters the inner cavity of the gas-liquid separation component 61 from the inlet 613, wherein the liquid-phase working fluid is located in the inner cavity, and the gas-phase working fluid flows out through the outlet 614 and flows to the subsequent circuit such as the compressor. When the gas-liquid separation component 61 is connected to the connecting part 141, at least part of the connecting head 612 is located in the fifth channel 135, the inlet 613 is connected to the fifth channel 135, the outlet 614 and the sixth channel 136 can be aligned, and the outlet 614 is connected to the sixth channel 136. Furthermore, a sealing arrangement is provided between the connecting head 612 and the fifth channel 135 and / or between the outlet 614 and the sixth channel 136 to prevent leakage of the working fluid.

[0039] In this embodiment, the connection portion 141 further includes a third mounting hole 137. The thermal management assembly 100" also includes a temperature and pressure sensor 53. With respect to the connection portion 141, the third mounting hole 137 communicates with the sixth channel 136. The sixth port 116 is located on one side of the connection portion 141. The openings of the fifth channel 135 and the sixth channel 136 are located on the same other side of the connection portion 141. The opening of the third mounting hole 137 is located on another side of the connection portion 141. These three sides are different sides of the connection portion 141. This helps avoid interference, improves the utilization of the connection portion 141, and facilitates connection of the thermal management assembly 100" with other components of the thermal management system. A portion of the temperature and pressure sensor 53 is located in the third mounting hole 137. At least the sensing portion of the temperature and pressure sensor 53 is located in the third mounting hole 137 and / or in the sixth channel 136. The temperature and pressure sensor 53 is fixedly connected or positionally fixedly connected to the connection portion 141. Specifically, this can be achieved by welding, bonding, threading, plugging, or screwing. The temperature and pressure sensor 53 is used to sense or measure the temperature and pressure of the gaseous working fluid flowing out of the outlet 614 of the gas-liquid separation component 61, to determine whether the working fluid meets the superheat requirements of the thermal management system in different modes, and then to provide feedback to the throttling element to adjust the valve opening size to ensure the safe operation of specific components in the subsequent circuit, such as the compressor.
