Description
Technical field
The invention belongs to heat sink technology field, refer in particular to a kind of composite heat sink.
Background technology
At present, the radiator on heating electric appliance element mostly use die casting or extrusion process shaping, its weak point is: the radiator of aluminium die casting is high due to siliceous composition, causes conductive coefficient to reduce, and radiating efficiency only reaches about 1/3rd of fine aluminium.And extruded heat sinks belongs to Mould Machining, although heat conduction and heat radiation efficiency is higher, profile is inflexible, is also difficult to meet the different actual demand of various watt level.
Summary of the invention
The object of this invention is to provide a kind of composite heat sink.
The object of the present invention is achieved like this:
A kind of composite heat sink, the middle part of aluminum soleplate offers the bar hole of one or more, the one side of aluminum soleplate is provided with the mounting groove that a row is above, each mounting groove is installed with a metallic composite fin.
Above-mentioned metallic composite fin have employed aluminum copper clad material.
Above-mentioned metallic composite fin is: the flanging being provided with 80-100 degree in the side of a rectangle composite sheet, middle part and the both sides of flanging are provided with breach, and the breach in the middle part of flanging is just to the bar hole on aluminum soleplate.
Above-mentioned metallic composite fin is: the flanging being provided with 90 degree in the side of a rectangle composite sheet.
The primary flat of above-mentioned metallic composite fin is perpendicular to the length direction of bar hole.
The quantity of the breach in the middle part of the flanging of above-mentioned metallic composite fin and one_to_one corresponding equal with the quantity of bar hole.
The concrete structure above-mentioned each mounting groove being installed with a metallic composite fin is: on aluminum soleplate, be arranged at intervals with the positive stop strip of a row 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 metallic composite fin is arranged stretches into metallized metal composite material fin and the integral formula structure of aluminum soleplate stamping connection in the mounting groove on the downside of cantilever press strip.
Above-mentioned aluminum soleplate is the more than one sidewall of an aluminium flat board or metal case.
The present invention gives prominence to compared to existing technology and useful technique effect is:
1, fin of the present invention adopts aluminum copper clad 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 feature of red copper good heat conductivity, thus increase substantially the heat dispersion of radiator.
2, the spacing between adjacent two fin of the present invention manufactures and designs by heat dissipation capacity size and air flow resistance requirement, and radiating efficiency is high.
3, fin area of the present invention can manufacture and design by heat dissipation capacity, can use flexibly and save material, and reduces production cost.
4, aluminum soleplate of the present invention and metallic composite fin strike out integral structure, be convenient to aluminum soleplate to metallic composite fin direct heat transfer, and firm reliability are high.
5, the present invention is applicable to the radiating element of the product such as street lamp, LED etc., power amplifier.
