Description
Technical Field
[0001] This utility model relates to the technical field of five-way electronic water valves, and in particular to an embedded five-way electronic water valve. Background Technology
[0002] In recent years, with the rapid development of the new energy vehicle industry, its thermal management system has become increasingly integrated and intelligent. Compared with traditional fuel vehicles, new energy vehicles have significantly different thermal management systems due to differences in drive type and energy architecture. New energy vehicle drive motors require high power and high speed, generating a large amount of heat during high-speed driving. If this heat is not dissipated in time, it will seriously affect the motor's performance and lifespan. To improve range, automakers often choose power batteries with high energy density and high discharge rate. However, excessively high energy density and discharge rate inevitably cause the battery to generate a large amount of heat during use. Overheating not only affects battery life but also easily leads to safety accidents. The thermal management system of new energy vehicles is relatively complex. Different operating systems have different temperature control requirements, resulting in varying coolant flow rates to each system. Therefore, new energy vehicles require an efficient thermal management system to ensure stable vehicle operation, and temperature control faces significant challenges. With increasingly stringent energy conservation and emission reduction policies, traditional automotive thermostats suffer from drawbacks such as "response delay" and "hysteresis characteristics," resulting in poor flowability and difficulty in accurately controlling flow rate, leading to low thermal management efficiency and failing to meet the high temperature control requirements of new energy vehicles. Therefore, the thermal management system of traditional cars is also being optimized. Some models now use electronic water valves to replace traditional thermostats for coolant regulation.
[0003] Traditional control systems for battery and motor thermal management in new energy vehicles currently rely on multiple electronic water valves to control various media flow channels within the thermal management system, maintaining these channels in series or parallel connection to achieve specific pipeline or proportional switching. This allows the thermal management system to achieve independent flow loops for each channel or to be adjusted to form a single flow loop. Commercially available electronic water valves are typically mounted on the manifold via valve bodies, occupying significant space and causing inconvenience for the placement of other components.

Then it flows out from the outlet channel, ultimately realizing the temperature regulation of the thermal management system.
