[0047] As the functional requirements of the thermal management system 1000 increase, the number of structural parts that need to exchange heat and the number of heat exchange modes that need to be met gradually increase. For example, in new energy vehicles, the passenger compartment needs to be heated or cooled, and in some cases, the drive motor group also needs to be heated or cooled. At the same time, during the operation of the thermal management system 1000, reducing the energy consumption of the thermal management system 1000 is also a technical problem that needs to be solved urgently.

[0048] like Figure 36 and Figure 37 As shown, to solve the above problems, an embodiment of the present invention provides a thermal management system 1000, which includes multiple heat exchange branches, each of which includes at least one heat exchanger, which is used to exchange heat with the element to be heat exchanged. For example, the heat exchanger can be at least one of an evaporator, a condenser, a radiator, a water-cooled plate, etc. In order to achieve different connectivity relationships between the above heat exchange branches in the thermal management system 1000 to form a heat exchange circuit, the thermal management system 1000 may also include a valve assembly and a pump assembly. The valve assembly, the pump assembly, and the heat exchanger are usually connected through connecting pipes. In this case, the thermal management system 1000 has a complex structure, a large number of pipes, and occupies a large space.

[0114] In the above-mentioned internal passage 400, the multiple openings included in each internal passage 400 can be connected in sequence to form a passage. Among the 20 internal flow paths of the thermal management device described above, a portion of the internal flow paths share a common flow path opening, which facilitates the simplification of the internal structure of the thermal management device compared to setting a different flow path opening for each internal flow path. By integrating the first pump assembly and the second pump assembly into the third flow path part A3, and integrating the third pump assembly and the fourth pump assembly into the fourth flow path part A4, on the one hand, the structure of the third flow path part A3 and the fourth flow path part A4 can be simplified, while at the same time facilitating the welding and sealing of the third flow path part A3 and the first flow path part A1, the fourth flow path part A4, and the second flow path part A2, thereby improving the sealing performance between the internal flow paths. Since some internal flow paths need to flow between the third flow channel component A3 and the second flow channel component A2, and part of the internal flow paths flow in the fourth flow channel component A4 and the first flow channel component A1, by arranging the third flow channel component A3 on the bottom side of the first flow channel component A1 and the fourth flow channel component A4 on the bottom side of the second flow channel component A2, it is convenient to shorten the flow path between the third flow channel component A3 and the second flow channel component A2, and shorten the flow path between the fourth flow channel component A4 and the first flow channel component A1, thereby simplifying the flow resistance and reducing the excessive size of the thermal management device in one direction.
