With the development of the times, there have been many big changes in food, clothing, housing and transportation. Cars have developed from the first generation of steam cars to the current new energy vehicles.

The automotive thermal management system is an indispensable component for every generation of cars. It is a collection of parts in the vehicle that are used to adjust the working temperature of the components and the temperature environment of the passenger compartment. It uses heat dissipation, heating, insulation and other means to The thermal management system is an important component in the vehicle to ensure that different components are in a suitable operating temperature range and the passenger compartment is maintained at a suitable temperature to ensure the comfort, functional safety and service life of the vehicle.

The solenoid valve plays a role in adjusting the mixing ratio of hot and cold water flow in the thermal management system of new energy vehicles, and is an important component of new energy vehicles.

The solenoid valve consists of a container, a solenoid valve body and a controllable solenoid coil. When current flows through the solenoid coil, a magnetic field is generated, which affects the valve plate on the solenoid valve body, causing it to rotate to control the flow of fluid. In addition, the solenoid valve can also control the water flow by detecting the position of the solenoid valve body, so that the water flow can be accurately controlled.

In the thermal management system of new energy vehicles, solenoid valves are used in circuits such as motor electronic control systems, air conditioners, and batteries. Generally, 2-5 two-way/three-way/four-way and multi-way valves are required. In the thermal management of new energy vehicles, multiple conventional three-way valves and four-way valve combinations are used to switch between various modes. Using multiple water valves is not only more costly, but also requires more water pipes to be connected, resulting in a higher risk of failure. , and also increases the complexity of the vehicle layout. Therefore, judging from the trend, multi-way valves and three-way/four-way valves are generally used in complex modes, and the trend of integration of water valves is becoming more and more obvious.

According to relevant data, China's new energy vehicle electronic water valve market size will be 1.98 billion yuan in 2022. In the next few years, the market size will show a growth trend, and it is expected that by 2027, the scale will reach 3.51 billion yuan.
