Abstract

The utility model discloses a radiator structure of a heat conducting pipe, which is provided with a laminated heat radiating fin set. A heat radiating fin is provided with a plurality of opposing through holes. The two ends of the heat conducting pipe are bent into declination shapes at an identical proper angle, and the heat conducting pipe is provided with two parts of a declination segment and a flat segment. The declination segment is penetrated and fixedly welded in the through holes, and the heat radiating fin set is fixed on the declination segment of the heat conducting pipe. The flat segment of the heat conducting pipe is fixed in a groove which is provided by a heat-collecting block, and can be directly contacted with a heat source to rapidly conduct heat to each heat radiating fin. No heat radiating fins block between the heat-collecting block and a fan, which makes the air current of the fan be output more smoothly, and the back-pressure and the noise of the air current are reduced. Whereas, the declination angles of the heat radiating fins can even conduct the air current of the fan to the space between every two radiation fins, and the heat radiated to air is accelerated.

Description

The heat pipe heat spreader structures

Technical field
