The new energy automobile thermal management system has great differences in power source, engine structure and the like. Compared with the traditional fuel oil vehicle, the air conditioning system power source converts the battery from the engine, and an important heat source is lost during heating.

Waterway conversion valves in the market are mostly three-way and four-way structures. In order to realize all the functions, the cooling pipeline needs to be connected with a plurality of valves in series, so that the pipeline is complex, and the requirements of a new energy vehicle heat management system cannot be well met, as shown in fig. 16 and 17, the cooling pipeline is a waterway system inside the new energy vehicle heat management system, and a battery loop, a Chiller (cooler) loop, an HVCH (heating) loop, a motor loop and an air conditioner loop are matched with other auxiliary valve structures mainly through two four-way valves, so that the pipeline is complex.

The patent of the invention with the publication number of CN111322432B discloses a six-way valve, which realizes the communication of different branch pipelines through the rotation of a valve core, but the dynamic sealing surface of the six-way valve is arranged on the side surface of the circumference, the rotation resistance is large, the sealing effect is poor, and if the sealing effect is improved, the rotation resistance is larger, so that the valve is difficult to rotate.
