Detailed Description

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the utility model thus described is only a part, but not all, of the utility models described. All other utility models obtained by those skilled in the art without making any creative effort based on the utility models in the present utility model are within the protection scope of the present utility model.

Referring to fig. 1-4, the present utility model provides a technical solution:

the aluminum radiating fin without sharp edges comprises a heat conducting bottom plate 1, wherein mounting grooves 3 are formed in the front end and the rear end of the heat conducting bottom plate 1, and clamping plates 5 are arranged in the mounting grooves 3; the radiating fins 2 are regularly arranged on the heat conducting bottom plate 1; the heat dissipation fins 2 are installed on the heat conduction bottom plate 1 through the installation grooves 3 to dissipate heat.

Wherein, radiating fin 2 longitudinal section is trapezoidal, and its top is the arc, and the installation of being convenient for avoids when the installation, has sharp edges and corners fish tail installer.

In this embodiment, the bottom surface bilateral symmetry of fin 2 is equipped with the connecting block 21 that longitudinal section is trapezoidal, and the connecting groove 11 with connecting block 21 size position looks adaptation is opened to heat conduction bottom plate 1 top surface for fin 2 is fixed on heat conduction bottom plate 1 through inserting connecting block 21 in connecting groove 11, and the installation is more convenient, and every fin 2 all is the separation, only need take out it when certain fin 2 damages add one again can.
