Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile water valves, in particular to an electronic water valve for new energy vehicles. Background Art
[0002] Electronic water valves regulate the mixing ratio of hot and cold water in the thermal management system of new energy vehicles and are a crucial component. With the rapid development of new energy vehicles, electronic, intelligent, and comfortable features have become mainstream, leading to an increasingly complex layout of vehicle thermal management systems.
[0003] To optimize piping layout and reduce system complexity, electronic water valves are widely used in automotive thermal management systems. Common electronic water valves are primarily categorized as two-way, three-way, and multi-way valves. A single multi-way valve can replace several two-way and three-way valves, offering a high level of integration. In mainstream vehicle thermal management systems, electronic water valves are used in circuits such as the motor control system, air conditioning, and battery. In complex modes, multi-way valves are typically used in conjunction with other valves.
[0004] At present, traditional multi-way water valves on automobiles are basically water valves with valve ports directly set in a straight-through channel on the side of the valve body or water valves with valve ports directly set in a straight-through channel at the bottom of the valve body. After the valve ports of the multi-way water valve of the first structure are connected with pipes, the overall volume will be very large, and it will take up a large space in the entire vehicle when installed on the automobile. The space between the valve ports of the multi-way water valve of the second structure is small, and the operating space for installing the pipeline is small, which affects the assembly time of the entire vehicle.
[0005] To address the above issues and optimize both overall footprint and installation space, we offer multi-way electronic water valves for new energy vehicles. These valves are highly versatile and can meet the operating mode requirements of different customers' thermal management systems. Furthermore, they can replace independent two-way / three-way valves to optimize piping layout, thereby reducing the size, weight, and cost of the thermal management module. Utility Model Content
