Background

In recent years, with the rapid development of the new energy automobile industry, the thermal management system of the new energy automobile has become more and more integrated and intelligent. Compared with the traditional fuel oil automobile, the new energy automobile has a very different thermal management system due to different driving forms and energy architectures. The new energy automobile driving motor requires high power and high rotating speed, so that a large amount of heat is generated in the high-speed driving process, and if the heat is not taken away in time, the performance and the service life of the motor are seriously affected; in order to improve the cruising ability, automobile manufacturers often select power batteries with high energy density and high discharge multiplying power, but the excessively high energy density and discharge multiplying power inevitably lead to a large amount of heat generated in the use process of the batteries, and the service life of the batteries can be influenced due to the excessively high temperature, and safety accidents are also easy to cause. The new energy automobile thermal management system is more complicated, and the temperature control requirements of different working systems are different, so that the flow of the cooling liquid flowing to each working system is different. Therefore, new energy automobiles require efficient thermal management systems to ensure stable operation of the vehicle, and the problem of temperature control thereof faces a great challenge. The traditional automobile thermostat has the defects of response delay, hysteresis characteristic and the like, has poor fluxion, is difficult to accurately control the flow, causes low heat management efficiency, and cannot meet the high requirement of a new energy automobile on temperature control. Therefore, the thermal management system of the traditional automobile is gradually optimized, and the electronic water valve is used for replacing the traditional thermostat for cooling liquid adjustment on part of automobile types.

The device has the main effects of adaptively adjusting the flow of the cooling liquid of each pipeline according to the temperature change of different working positions, ensuring that batteries, motors and the like are in the optimal working temperature environment, and achieving the purposes of saving energy, reducing emission and improving the energy utilization rate.

Through the structure of design case and disk seat, can realize the flow proportion regulation's function. However, because the outside flow channels are distributed on the side wall, and the water inlet and outlet directions are up and down, the fluid needs to be commutated for many times when flowing through the valve core, so that the pressure drop of the fluid is greatly increased, the energy is wasted, the service lives of a thermal management system and other elements are seriously influenced, and even safety accidents are caused. The side wall flow channel of the water valve also makes the whole valve body huge, which is not beneficial to miniaturization and light weight of the thermal management system and affects the arrangement of other elements and flow channels on the thermal management system; and the response time and the adjustment precision of the flow adjustment of the water valve are greatly influenced by the volume.
