Abstract

Provided is a thermal management integration module ( 100 ) and an electric vehicle. The thermal management integration module ( 100 ) includes: a multi-channel integration board ( 110 ) having a plurality of cooling connection pipelines ( 111 ) formed therein, the multi-channel integration board ( 110 ) being configured as a carrier member for the thermal management integration module ( 100 ); and at least two thermal management components mounted on the multi-channel integration board ( 110 ) and connected to each other by the plurality of cooling connection pipelines ( 111 ). The design of the multi-channel integration board can not only serve as a connection channel between different thermal management components, but also serve as a carrier member for the entire integration module to enable the thermal management components to be integrated on the multi-channel integration board, forming the thermal management integration module with low costs, a light weight, and a small arrangement space.
