The heat dissipation assembly 100 is fixed to the rear plate of the case 210 by screws through screw posts.

Wherein the motor 122 is clamped in a cylindrical slot in the bracket 130 and secured by screws. The motor 122 is powered by the circuit board 140, the motor and the circuit board are connected by a connecting wire, and the bracket 130 is provided with a corresponding wire outlet groove for wiring.
