In this embodiment, since the third interface part S3 and the seventh interface part S7 are respectively located on opposite sides of the block body part 20, the flow path management assembly 100 further includes a pipe 23, one end of the pipe 23 is hermetically connected to the outdoor heat exchanger 24, the other end is hermetically connected to the block body part 20, and a lumen of the pipe 23 communicates the first flow channel and the ninth pore passage 110.

In some other embodiments, the flow path management assembly 100 includes a compressor 2, the compressor 2 being mounted with the block portion 20, the compressor 2 being located alongside the block portion 20. The first port 101 communicates with the outlet of the compressor 2, and the seventh port 107 communicates with the inlet of the compressor 2.

The appearance form of the valve core assembly does not influence the realization of functions, the appearance form of the valve core assembly is selected according to requirements, even different valve core structures are selected to realize the same functions, and the valve core assembly cannot be understood as different parts.

It is to be understood that the mounting in this application may be a direct mounting, or an intermediate spacer element mounting; the installation part is in sealing connection, and the sealing connection can be realized by adopting modes of brazing, gluing and the like. In the application, "communication" between two parts can be direct communication, also can realize the communication through the pipeline, can only establish the pipeline intercommunication in the system between two parts, also can still be equipped with valve member or other parts between the two and communicate after.

When the flow path management assembly 100 is applied to a thermal management system, some pipelines can be omitted, and the structure is simplified. All the valve core assemblies in each embodiment are located on the same side of the block body portion 20 in the thickness direction, and the plurality of valve core assemblies are distributed in a matrix manner, so that the miniaturization of the flow path management assembly 100 is facilitated.

Although the present application has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the application, and all changes, substitutions and alterations that fall within the spirit and scope of the application are to be understood as being covered by the following claims.
