Heat dissipation device

A heat dissipation device comprises a fixed substrate, a heat pipe group, a flexible uniform temperature plate and a rotatable auxiliary heat dissipation fin group. The heat pipe group is fixed on the fixed substrate, the flexible uniform temperature plate is fixed above the heat pipe group, and the rotatable auxiliary heat dissipation fin group is connected to the flexible uniform temperature plate so as to rotate relative to the heat pipe group. 一种散热装置包含有一固定基板、一热管组、一柔性均温板以及一可旋转辅助散热鳍片组。热管组固定于固定基板，柔性均温板固定于热管组的上方，而可旋转辅助散热鳍片组，连接于柔性均温板，以相对热管组旋转。
