Detailed implementation manners

[0024] The features and exemplary embodiments of various aspects of the present invention will be described below. To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. In this article, relational terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0025] Refer to Figures 1 - 3 , Figures 11 - 15 , one embodiment of the present application provides a thermal management component, which is applied to an automotive thermal management system. The refrigerants flowing in the thermal management system include R290, R32, R1234yf, R152a, and NH3. Specifically, R290 is adopted in this embodiment. In the thermal management system applied in this embodiment, the refrigerant exchanges heat with the coolant, mainly through the coolant to exchange heat with other sub-components of the whole vehicle, protects the sub-components through which the refrigerant flows, and reduces the risk of refrigerant leakage to the outside. The specific introduction is as follows.

[0026] Refer to Figures 11 - 15, an embodiment of the present application discloses a thermal management component, including a housing 2, a flow path component 1, and a plurality of first fluid management components 3. At least a part of the communication channels in each first fluid management component 3 is used for circulating refrigerant. The communication channels refer to the channels through which the refrigerant or coolant flows in the first fluid management component 3. The communication channels include the channels for circulating fluid in the first fluid management component and the channels for circulating fluid formed by the first fluid management component and other components together, including refrigerant valve ports, refrigerant valve cavities, heat exchange channels of heat exchangers, interfaces of heat exchangers, interfaces of accumulators, etc. Specifically, the first fluid management component 3 includes components for circulating refrigerant, such as expansion valves, refrigerant valves, gas-liquid separators, accumulators, etc. The first fluid management component 3 also includes components with a part of the area for circulating refrigerant, such as a water-cooled condenser that has both a refrigerant channel and a coolant channel. The first fluid management component 3 is fixedly connected or limit-connected to the housing 2 or the flow path component 1. "Fixed connection" includes welding, riveting, screw connection, etc. "Limit connection" includes snap connection, threaded connection, etc. The above-mentioned fixed connection or limit connection between the first fluid management component 3 and the housing 2 or the flow path component 1 means that the housing 2 and the flow path component 1 serve as the carriers of the first fluid management component 3, that is, the first fluid management component 3 is directly or indirectly fixedly connected or limit-connected to the housing 2 and the flow path component 1. The flow path component 1 is fixedly connected to the housing 2, and the connection between the flow path component 1 and the housing 2 is sealed. The sealing arrangement includes setting a seal at the connection between the flow path component 1 and the housing 2, and also includes an integral structure or welding of a part of the flow path component 1 and the housing 2 to achieve sealing. Specifically, in this embodiment, the flow path component 1 and the housing 2 are connected by screws, and a seal is provided between the flow path component 1 and the housing 2. The flow path component 1 has flow paths, at least two communicating flow paths. The thermal management component has communication channels, and the walls forming the communication channels are located in the first fluid management component 3. At least a part of the communication channels is in communication with the flow paths of the flow path component 1.

[0027] The thermal management component has a closed cavity 10. The walls forming the closed cavity 10 are located between the flow channel component 1 and the housing 2. In some embodiments, the flow channel component 1 is at least partially made of plastic, and a coolant flows through the flow channels in the flow channel portion of the flow channel component 1. That is, the flow channel component 1 is a water-side flow channel plate. The walls forming the closed cavity 10 are located between the water-side flow channel plate and the housing 2. "The communication channel communicates with the flow channels of the flow channel component 1" in such embodiments includes: the communication channel of the coolant of the heat exchanger for heat exchange between the refrigerant and the coolant in the first fluid management component 3 communicates with the flow channels in the flow channel portion. In other embodiments, the flow channel component 1 is at least partially made of metal, and a refrigerant flows through the flow channels in the flow channel portion of the housing 2. That is, the flow channel component 1 is a refrigerant-side flow channel plate. The walls forming the closed cavity 10 are located between the refrigerant-side flow channel plate and the housing 2. "The communication channel communicates with the flow channels of the flow channel component 1" in such embodiments includes: the communication channels of all the first fluid management components 3 for flowing the refrigerant communicate with the flow channels in the flow channel portion. In the above two types of embodiments, the material of the housing 2 is not limited and can be plastic, metal or other materials. In addition, it is not limited to the flow channel component 1 having flow channels. The housing 2 can also have flow channels for flowing the coolant or the refrigerant. The flow channel component 1 has at least two communication flow channels. In some embodiments, the coolant flows through the flow channel portion, and multiple flow channels in the flow channel portion communicate through the communication channels of water-side components such as a water pump 91 and a water valve 92. In other embodiments, the refrigerant flows through the flow channel portion, and multiple flow channels in the flow channel portion communicate through the communication channels of refrigerant-side components such as a refrigerant valve 35 and a heat exchanger 32. At least some of the multiple first fluid management components 3 are located in the closed cavity 10. In some embodiments, all the components that flow the refrigerant or some regions that flow the refrigerant are selected and arranged in the closed cavity 10. In other embodiments, some components that are prone to leakage can also be arranged in the closed cavity 10, and the components that are not prone to leakage are arranged outside the closed cavity 10, or a part of a single first fluid management component that is prone to refrigerant leakage is sealed in the closed cavity. Of course, if there is enough space in the closed cavity 10, some components that only flow the coolant can also be selectively arranged in the closed cavity 10. The closed cavity 10 of the present application is isolated from the flow channels in the flow channel portion and the communication channels of the first fluid management component 3, which only means that the closed cavity 10 is not functionally used for flowing the refrigerant or the coolant. When there is no leakage, the closed cavity 10 is isolated from the flow channels and the communication channels of the first fluid management component 3. After leakage occurs, the closed cavity 10 is communicated with the flow channels or the communication channels of the first fluid management component 3, but this situation is not desired. Therefore, the situation where the closed cavity 10 is communicated with the flow channels or the communication channels of the first fluid management component 3 after leakage is also within the scope of the above description of "the closed cavity 10 is isolated from the flow channels in the flow channel portion and the communication channels of the first fluid management component 3".

[0028] In this embodiment, a closed cavity 10 is constructed in the thermal management component. The first fluid management component 3 for circulating the refrigerant is arranged in the closed cavity 10, and the corresponding leakage point is also located in the closed cavity 10. If refrigerant leakage occurs, the closed cavity 10 protects against the external leakage of the refrigerant (i.e., the refrigerant leaks into the external space of the thermal management component). The housing also protects the first fluid management component, improving the safety of using flammable refrigerants in the field of vehicle thermal management. In addition, part of the wall of the flow channel component 1 is used to construct part of the wall of the closed cavity 10, which is more compact than adding an entire housing outside the thermal management component for protection.

Considering the difficulty of forging a metal housing, the housing 2 is preferably made of plastic.

[0037] In some embodiments, considering that the recess depth is too deep and it is difficult to demold the housing 2 during molding, the housing 2 is divided into multiple parts. Refer to Figure 1 and Figure 2 , the housing 2 includes a first sub-housing 21 and a second sub-housing 22. The first sub-housing 21 and the flow channel component 1 are of an integral structure.

The thermal management component includes a third seal 83. The housing 2 has a wire harness window 60. The adapter 62 is located in the wire harness window 60. The main body portion 620 of the adapter 62 is fixedly connected to the housing 2.

In this embodiment, the main body portion 620 of the adapter 62 is screwed to the housing 2. The third seal 83 is arranged circumferentially along the wire harness window 60. One side of the third seal 83 abuts against the housing 2, and the other side abuts against the main body portion 620 of the adapter 62 to achieve the sealing of the wire harness window 60.
