Thermal management assembly with flexible connecting component

Abstract

A thermal management assembly includes a flow channel component, a box body, a sensor, a control component and a flexible connecting component. The flow channel component has a first expansion coefficient. The box body has a second expansion coefficient different from the first expansion coefficient. The sensor and the flow channel component are fixedly connected. The control component and the box body are fixedly connected. One end of the flexible connecting component is electrically connected to the sensor, and another end of the flexible connecting component is electrically connected to the control component. The flexible connecting component disclosed in the present disclosure is deformable, thereby reducing a relative displacement between the flow channel component and the box body due to different degrees of expansion when the thermal management assembly operates.
