Background technology
Hot pipe technique is the heat transfer element of a kind of being called " heat pipe " of George Ge Luofo (George Grover) invention of U.S. Los Alamos (Los Alamos) National Laboratory in 1963, it takes full advantage of the Rapid Thermal hereditary property of heat-conduction principle and refrigeration filling, see through heat pipe the heat of thermal objects is delivered to rapidly outside thermal source, its capacity of heat transmission surpasses the capacity of heat transmission of any known metal.
Heat pipe is widely used in radiator manufacturing at present, for example on market, the stem stem of emerging high-power LED phase-change radiator just adopts gravity assisted heat pipe technology, gravity assisted heat pipe outer wall is in conjunction with radial fin, be commonly called as " heronsbill radiator ", the application for a patent for invention that can be CN103196116A referring to notification number open " for the modified gravity force heat pipe radiator of great power LED ".
Existing phase-change heat sink technology is mainly copper or the phase transformation of aluminothermy pipe and microflute faciation and becomes.Heat pipe is mainly to form capillary structure at the congruent metal dust of the inner surperficial coating sintering of metal tube, is conducive to liquid backflow; When hot junction liquid evaporation, steam is condensed into after liquid at cold junction, by capillary structure, is back to hot junction to supplement, and heat exchange function has moved in circles.Microflute group is mainly the some microflutes of machining process on flat board, utilizes the compound phase transformation strengthening heat transfer mechanism of the heat sink high strength of micro-scale groove group structure to carry out heat exchange.Because needing complicated technique, realizes copper heat pipe sintering, Master Cost, and processing charges is very high, and metal dust stirs simultaneously needs complicated organic solvent.Microflute group Technology Need carries out machining by the mode of cutting, and processing charges is high, and productivity ratio is low, and exchange capability of heat is limited.
Summary of the invention
The deficiency existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of New LED heronsbill radiator, its main body adopts aluminum alloy extrusion section bar, the cavity body structure that comprises integrated extruding, adopt phase change technique to conduct heat, simplified manufacturing process, alleviated product weight, improve heat-sinking capability, extended the whole lamp life-span.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of New LED heronsbill radiator, comprise that inside is provided with the body of cavity, in described cavity, be provided with the working medium that can carry out phase-change heat transfer, the surrounding of body is laid with some radiating fins, on body, the two ends of corresponding described cavity are covered with respectively top cover and bottom, body, top cover and bottom are respectively integrated die cast structure, and the inner surface of described bottom is provided with the microneedle array that some projections form.
Wherein, described projection is column, halfpace shape or cone-shaped.
Wherein, the outer surface of described bottom is provided with integrated wire lead slot, and the outer end of described wire lead slot is provided with bent radial portion.
Wherein, the outer surface of described top cover and described bottom is respectively equipped with integrated installing hole.
Adopt after technique scheme, the advantage that compared to the prior art the utility model had is:
New LED heronsbill radiator described in the utility model, its main body adopts aluminum alloy extrusion section bar, the cavity body structure that comprises integrated extruding, adopt phase change technique to conduct heat, by the inner surface die cast microneedle array at bottom, increase the heat transfer problem that working medium heat exchange area solves high heat flux, adopt extrusion process, one-shot forming, solid-liquid heat exchange side surface area is improved to several times, exchange capability of heat is greatly improved, can meet present stage great power LED cooling demand, cost significantly reduces simultaneously; Adopt in addition die cast, can make complicated fabrication hole, such as through wires hole, screw hole etc.
