Heat dissipation device and terminal device

Abstract

A heat dissipation device is used to dissipate heat from a working element. The heat dissipation device includes a manifold, a connecting pipe, and a fixing assembly. The fixing assembly includes a fixing frame, a heat dissipation component, a limiting member, and a wire clip. The fixing frame includes a first plate and a second plate; the heat dissipation component is located between the first plate and the second plate, and the connecting pipe connects the manifold and the heat dissipation component; the limiting member is disposed on the surface of the heat dissipation component facing the first plate, and the space between the heat dissipation component and the second plate is used to accommodate the working element; the wire clip is rotatably inserted between the heat dissipation component and the limiting member, and the wire clip is used to switch from a first position to a second position and drive the heat dissipation component to move towards the second plate to compress the working element. This application also provides a terminal device.
