The heat dissipation frame 801 and the heat dissipation plates 802 realize the effect of assisting the heat dissipation assembly 3 to dissipate heat. Generally, the heat dissipation assembly 3 itself has stable heat dissipation effect, but the electronic equipment has uncertain intermittent use. The simple heat dissipation assembly 3 cannot guarantee the heat dissipation during peak period. Therefore, the auxiliary assembly 8 is installed on the top of the shell assembly 4. When the auxiliary assembly 8 operates, it conducts air flow to the heat dissipation assembly 3, thereby assisting to increase the contact between the heat dissipation assembly 3 and the air flow, enhancing the heat exchange efficiency.
