Description

Technical Field

[0001] This utility model relates to the field of fluid control, and in particular to a multi-way valve and thermal management system. Background Technology

[0002] Existing thermal management systems for new energy vehicles generally adopt a distributed layout with multiple independent valve bodies, which leads to complex piping, a significant increase in pressure drop, increased power loss, limited installation space, and a limited number of openings, making it difficult to meet the multi-directional flow requirements of complex systems. The distributed design requires a large number of pipe connections, which not only increases material costs but also increases the flow resistance of coolant due to the excessive length of the pipes, affecting heat exchange efficiency and indirectly reducing driving range.

[0003] Therefore, it is necessary to provide a multi-way valve and thermal management system to overcome the defects mentioned above. Utility Model Content
