AI Technical Summary

Technical Problem

In the existing thermal management system, switching between cooling and heating requires the installation of multiple shut-off valves, resulting in many parts and high costs. The shut-off valve needs to be continuously supplied with power when it is turned on or cut off, increasing energy consumption.

Method used

A multi-way valve is designed, including a valve body and a valve core, which is rotatably connected to the valve body, and a plurality of valve ports are provided on the valve body, and the valve core can selectively connect or cut off these valve ports, thereby realizing the switching between cooling and heating.

Benefits of technology

Through the integrated design of multi-way valves, instead of multiple stop valve structures, the assembly and adjustment are simplified, manufacturing costs are reduced, and the position can be kept unchanged after the valve core is rotated, without continuous power supply and energy consumption are reduced.

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, and a valve port is formed in the valve body; the valve ports comprise the first valve port, the second valve port, the third valve port and the fourth valve port, and the valve element is arranged in the mode that the first valve port can be selectively communicated with the second valve port and the third valve port, and the fourth valve port can be selectively communicated with the third valve port. Or the fourth valve port and the second valve port are cut off. The multi-way valve is of an integrated design, can replace a plurality of stop valve structures, and can be conveniently assembled, connected and adjusted and matched, so that the manufacturing cost is reduced.
