Heat dissipation module

Abstract

A heat dissipation module, which comprises a heat dissipation piece, a fan, a heat conduction coating material and a heat conduction piece, is disclosed. The heat conduction coating material is used for improving the thermal radiation coefficient of the heat dissipation piece. Accordingly, when elements transmit heat to the heat dissipation piece via the heat conduction piece, more heat is transmitted to the air via thermal radiation manner. Next, the fan sucks heated air to achieve the effect of heat dissipation.
