AI Technical Summary
In the existing technology, the heat exchange efficiency of high-temperature refrigerant and low-temperature refrigerant is low and they cannot effectively insulate heat during the flow process in the flow combination four-way valve, which leads to a reduction in the heat exchange efficiency of the thermal management system.
A combined four-way valve is designed. By setting a hollow part and an angled channel structure in the valve seat assembly, the heat exchange between high-temperature and low-temperature refrigerants is reduced. The hollow part is used to increase the blocking effect, and the weight and volume are reduced by the one-piece molding process.
It effectively reduces heat exchange between high-temperature and low-temperature refrigerants, improves the heat exchange efficiency of the thermal management system, and reduces the weight and installation volume of the combined four-way valve.
