Heat dissipation module

A heat dissipation module, applied to cooling a microprocessor, comprising:

• a base, assembled on the microprocessor;
• a diversion pipeline, connected to the base, providing a diversion direction and a heat insulated pipe-wall, wherein the diversion pipeline is partitioned off into an inside portion and an outside portion with the heat insulated pipe-wall and wherein the heat insulated pipe-wall reduces the heat conduction in the diversion direction of the diversion pipeline;
• and
• a plurality of heat conductive pieces, fixed on the diversion pipeline, wherein each two neighboring heat conductive pieces are separated with the heat insulated pipe-wall of the diversion pipeline, and wherein each of the heat conductive pieces has a heat dissipation direction from the inside portion to the outside portion of the diversion pipeline and across the diversion direction;
• and wherein each of the heat conductive pieces comprises an inner fin inside the diversion pipeline and an outer fin outside the diversion pipeline, and both of the inner fin and the outer fin are substantially vertical to the heat insulated pipe-wall;
• a fan, assembled on the outside portion of the diversion pipeline, providing a cool air for the heat conductive pieces.
