AI Technical Summary
Technical Problem
In the existing thermal management system, the series heat pump system needs to be combined with a shut-off valve and an expansion valve, resulting in a large space and high cost of the valve.
Method used
A multi-way valve is designed, including a valve body and a valve core. The valve core can be rotatably connected to the valve body. A multiple valve port is provided on the valve body. The valve core can realize the conduction state of different valve ports, replacing the traditional shut-off valve and expansion valve.
Benefits of technology
Simple switching of refrigerant flow direction and pressure adjustment are achieved, reducing the number of valves and space occupied, and reducing costs.

Abstract
The utility model relates to a multi-way valve for refrigerants, a heat management system and a vehicle. The multi-way valve comprises a valve body and a valve element. The valve element is rotatably connected to the valve body, valve ports are formed in the valve body, and the valve ports comprise the first valve port, the second valve port and the third valve port; the valve element is arranged in the mode that the first valve port can be partially communicated, and / or the second valve port can be completely communicated or cut off, and / or the third valve port can be completely communicated or cut off. According to the multi-way valve, one valve can be connected with a plurality of pipelines, meanwhile, the multi-purpose effect of one valve can be achieved, the existing matching mode of a stop valve and an expansion valve can be replaced, the space occupied by the valve is reduced, meanwhile, the number of the valves is reduced, and cost is reduced.
