Description

Technical Field

[0001] This application relates to the field of eight-way valve technology, and more particularly to an eight-way valve, a thermal management system, and a vehicle. Background Technology

[0002] With the rapid development of the new energy vehicle industry, automotive thermal management systems are evolving towards modularization and integration. Water valves, as key components on the water side of thermal management systems, play a crucial role in flow channel switching and flow regulation within the water-side circuit. To match integrated thermal management modules, water valves are evolving from traditional three-way and four-way valves to those with more channels. Currently, most water valves on the market are three-way or four-way valves, with a smaller number capable of five-way, six-way, seven-way, eight-way, and nine-way valves. However, with the increase in operating modes, the number of valves required by the thermal management system gradually increases, leading to higher system costs, greater spatial layout complexity, and reduced energy efficiency. Therefore, it is necessary to design multi-way valves with more operating modes to reduce the number of valves, lower system costs and layout complexity, and improve energy efficiency.

In this operating mode, the battery 170 and electric drive 180 systems dissipate heat through external heat exchanger 190.
