Description
Technical Field
[0001] This utility model relates to the field of automotive thermal management system technology, and in particular to a dual-drive dual-proportional control eight-way valve. Background Technology
[0002] With the rapid transformation of the global automotive industry towards new energy vehicles, the thermal management systems of these vehicles have become increasingly complex and critical. In the traditional automotive sector, thermal management systems primarily rely on individual three-way and four-way valves for heat management. Their sealing principle involves precisely controlling the fit dimensions between the valve core and valve housing, relying on the compression of the sealing element between them to reduce leakage in non-connected pipelines. However, this approach has gradually revealed numerous limitations in the face of the complex thermal management requirements of new energy vehicles.
[0003] With the rapid development of the new energy vehicle industry, thermal management systems not only need to achieve basic heat distribution, but also need to ensure the efficient operation of multiple circuits such as batteries, motors, and air conditioning to meet the stringent range requirements of new energy vehicles. This necessitates the use of control valves with multiple channels, i.e., multi-way valves, to precisely control the on / off state of each circuit and the switching of channels.
[0004] To achieve precise flow control and proportional adjustment of loop flow, existing technologies often rely on individual three-way valves or five-way valves. However, this approach has significant drawbacks. Regarding integrated module layout, the combination of individual valves occupies a large amount of space, increasing the difficulty of layout in vehicles with limited interior space. Furthermore, the use of multiple individual valves significantly increases costs, hindering cost control and market promotion for new energy vehicles. Utility Model Content
