TECHNICAL FIELD

The heat management system of new energy vehicles, especially electric vehicles and hybrid vehicles, plays a crucial role in the performance, safety and comfort of vehicles. The heat management system not only controls the working temperature of key components such as batteries, motors and electronic control systems, but also directly affects the vehicle's range, charging speed and overall energy efficiency. As one of the core components of the heat management system of new energy vehicles, the multi-way valve precisely controls the flow direction and flow rate of the coolant to meet the cooling or heating requirements under different working conditions. Traditional multi-way valves are designed based on mechanical principles, and the flow path is switched by the rotation or movement of the valve core. With the continuous progress of new energy vehicle technology, the performance requirements of multi-way valves are becoming increasingly high.
[0003] However, the existing heat management multi-way valve seals the valve core with a separate sealing ring. The sealing ring is single-sided, with a small compression size of the sealing surface. The separate sealing ring requires high installation precision and is difficult to install, and there is a risk of leakage if the sealing ring is not installed properly. At the same time, the sealing surface that cooperates with the sealing ring is composed of the upper and lower housings, and there is always a gap after assembly, which cannot be avoided. Internal leakage can cause the heat pump heat management system to fail or perform poorly. The existing multi-way valve core sealing ring is limited by structural defects and cannot be made thicker. The compression size of the sealing ring is limited, and the small compression surface is prone to wear and tear, leading to internal leakage.
