The first fluid management component 3 is fixedly connected or limit-connected to the shell 2 or the flow channel component 1, and the "fixed connection" is described as follows: ” includes welding, riveting, screw connection, etc., and “limited connection” includes snap connection, threaded connection, etc. The above-mentioned first fluid management component 3 is fixedly connected or limitedly connected with the shell 2 or the flow channel component 1, including the shell 2 and the flow channel component 1 as the carrier of the first fluid management component 3, that is, the first fluid management component 3 is directly or indirectly fixedly connected or limitedly connected with the shell 2 and the flow channel component 1, the flow channel component 1 is fixedly connected to the shell 2, and the connection between the flow channel component 1 and the shell 2 is sealed, wherein the sealing arrangement includes a sealing member provided at the connection between the flow channel component 1 and the shell 2, and also includes a part of the flow channel component 1 and the shell 2 as an integral structure or welding to achieve sealing. Specifically, in this embodiment, the flow channel component 1 and the shell 2 are connected by screws, and a sealing member is provided between the flow channel component 1 and the shell 2. The flow channel component 1 has a flow channel, at least two connected flow channels, and the thermal management component has a connecting channel. The wall forming the connecting channel is located in the first fluid management component 3, and at least part of the connecting channel is connected to the flow channel of the flow channel component 1.

[0028] The thermal management component has a closed cavity 10, and the walls forming the closed cavity 10 are located between the flow channel component 1 and the shell 2. In some embodiments, the flow channel component 1 is at least partially made of plastic, and coolant flows in the flow channel of the flow channel portion of the flow channel component 1, that is, the flow channel component 1 is a water-side flow channel plate, and the walls forming the closed cavity 10 are located between the water-side flow channel plate and the shell 2. "The communicating channel is connected to the flow channel of the flow channel component 1" in such embodiments includes: the communicating channel of the coolant of the heat exchanger for heat exchange between refrigerant and coolant in the first fluid management component 3 is connected to the flow channel of the flow channel portion; in other embodiments, the flow channel component 1 is at least partially made of metal, and refrigerant flows in the flow channel of the flow channel portion of the shell 2, that is, the flow channel component 1 is an agent-side flow channel plate, and the walls forming the closed cavity 10 are located between the agent-side flow channel plate and the shell 2. "The communicating channel is connected to the flow channel of the flow channel component 1" in such embodiments includes: all communicating channels of the first fluid management component 3 for circulating refrigerant are connected to the flow channel of the flow channel portion. In the above two types of embodiments, the material of the shell 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 a flow channel. The shell 2 can also have a flow channel to circulate coolant or refrigerant. The flow channel component 1 has at least two connecting flow channels. In some embodiments, coolant circulates in the flow channel portion, and multiple flow channels in the flow channel portion are connected through connecting channels of water-side components such as the water pump 91 and the water valve 92. In other embodiments, refrigerant circulates in the flow channel portion, and multiple flow channels in the flow channel portion are connected through connecting channels of agent-side components such as the refrigerant valve 35 and the heat exchanger 32.

After leakage occurs, the closed cavity 10 is connected to the flow channel or the communicating channel of the first fluid management component 3, but this situation is undesirable. Therefore, the situation where the closed cavity 10 is connected to the flow channel or the communicating channel 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 channel of the flow channel part, and the closed cavity 10 is isolated from the communicating channel of the first fluid management component 3".
