Above-mentioned heat sink compound is: the flanging that is provided with 90 degree in a side of a rectangle composite sheet.
The primary flat of above-mentioned heat sink compound is perpendicular to the length direction of bar hole.
The quantity of the breach at the flanging middle part of above-mentioned heat sink compound equates with the quantity of bar hole and is corresponding one by one.
The concrete structure that is installed with a heat sink compound on above-mentioned each mounting groove is: be arranged at intervals with row's positive stop strip at the aluminum soleplate perpendicular to bar hole, the same side of each positive stop strip is unsettled to be provided with an opening and to form described mounting groove towards the cantilever press strip of positive stop strip, and the flanging that arranges on the heat sink compound stretches in the mounting groove of cantilever press strip downside metal compound heat dispersion sheet and the aluminum soleplate punching press formula structure that links into an integrated entity.
Above-mentioned aluminum soleplate is the more than one sidewall of an aluminium flat board or metal case.
The utility model compared to existing technology outstanding and useful technique effect is:
1, fin of the present utility model adopts the aluminum bronze composite material to make, the conductive coefficient 401w/m.k of red copper, the conductive coefficient of aluminium is 237w/m.k, utilizes the thermal radiation ability of aluminium high, and the characteristics of red copper good heat conductivity, thereby increased substantially the heat dispersion of radiator.
2, the spacing between adjacent two fin of the present utility model manufactures and designs by heat dissipation capacity size and air flow resistance requirement, and radiating efficiency is high.
3, fin area of the present utility model can manufacture and design by heat dissipation capacity, can use flexibly to save material, and reduces production costs.
4, aluminum soleplate of the present utility model and heat sink compound strike out integral structure, are convenient to aluminum soleplate to the heat sink compound direct heat transfer, and firm reliability is high.
5, the utility model is applicable to the radiating element of the products such as street lamp, LED etc., power amplifier.
