In preferred embodiment of the utility model, further comprise on the relative both sides of described cooling base one end and be equipped with the radiating fin perpendicular to described cooling base, and be equipped with jagged lug boss on the two sides of described radiating fin.
In preferred embodiment of the utility model, the free-ended cross section that further comprises described radiating fin is circular arc.
In preferred embodiment of the utility model, further comprise that the centre position of described cooling base is provided with square fixed part, described fixed part is provided with the installing hole that runs through described cooling base both sides.
In preferred embodiment of the utility model, further comprise the groove that is provided with that described cooling base caves in to the inside away from an end of described radiating fin, described groove is between two described pins.
In preferred embodiment of the utility model, further comprise on described cooling base and also be provided with two fixedly counterbores, two described fixedly counterbores lay respectively at two the drift angle places of described fixed part near described groove side.
Usefulness of the present utility model is: fin of the present utility model is by arranging by long by short radiating fin, increased the area of dissipation of fin, the best utilization by the thermolysis of radiating fin simultaneously, can greatly improve radiating efficiency, have advantages of simple in structure, easy to install, can carry out standardized production and batch machining, be beneficial to popularization.
