Radiation device

Abstract

The invention relates to a radiation device. A plurality of radiating fins are mutually buckled and connected to form an annular structure, the top and the bottom of each radiating fin are bent to form corresponding inlaying parts, the lateral face of each inlaying part and the lateral face of each radiating fin are inclined in a predetermined angle, and the joint between each radiating fin and each inlaying part is provided with a through hole; one side of each inlaying part, which is far away from the through hole, is extended to form a clamping part which can be inlaid in the through holesof the adjacent radiating fins, and the internal side and the external side of the clamping part are bent and folded to form clamp hooks which can penetrate through the through holes clamped on the adjacent radiating fins; the internal side of each radiating fin is bent and folded to form a leveling surface, the leveling surfaces of the radiating fins can form an annular containing space by enclosing, and a butting part is extended on the upper side of each leveling surface. The invention adopts the structure that the radiating fins are buckled and connected, the annular containing space whichcan contain a light source module is formed by utilizing the inlaying parts and the leveling surfaces of the radiating fins so that the light source module can uniformly conduct and dissipate the heat of a heat source by a plurality of radial array radiating fins, and therefore, the invention has favorable radiation effect.

Description

technical field [0001] The invention relates to a heat dissipation assembly, in particular to a heat dissipation device used for heat dissipation of light-emitting diodes, and belongs to the technical field of heat dissipation devices. Background technique [0002] Light brings many conveniences to human life, making people unable to completely see the surrounding environment and things in the dark. From the original firelight to the current electric light, and the electric light has become an indispensable part of life. , Manufacturers have also done a lot of research and development and improvement on electric lamps, from tungsten filament lamps and fluorescent lamps to halogen lamps and mercury lamps, and with the maturity of light-emitting diode technology, light-emitting diodes have become new light bulbs that manufacturers are committed to research and development today. [0003] Light-emitting diodes have the advantages of long life, power saving, fast start-up, no po...
