Abstract
An LED light source radiator comprises a metal basal body and a heat-radiating fin, wherein a multi-pore metal layer is arranged on the surface of the heat-radiating fin of the metal basal body to form a quick-speed passive heat-radiating structure. The LED light source radiator is compositely provided with the multi-pore metal layer on the heat-radiating fin, and the multi-pore metal has big heat-radiating area and high heat transfer efficiency, heat can be quickly radiated, and the density of the multi-pore metal is low, the weight of a radiator can be greatly lightened, and the heat-radiating effect is improved.
Description
Technical field:
The utility model relates to the passive heat radiation device of a kind of radiator, particularly led light source.
Background technology:
The radiating mode of general high-power LED light source all is to utilize radiator that heat is derived to distribute, its radiating mode has 2 kinds, first kind of radiator that is to use active heat removal modes such as water-cooled, though radiating effect improves, but the overheated led light source of burning of meeting under situations such as aggressive device fault, reliability is low, the cost height.Second kind is passive radiating mode, and what present use usually was more is aluminium alloy heat radiator, but because the effect of passive heat radiation is more limited, necessary employing is heavier radiator greatly.If this radiator and heavier LED street lamp are installed on the lamppost use, general setting height(from bottom) is a 6-10 rice, and the danger of street lamp increases, and especially runs into typhoon, earthquake and all may produce accident.If adopt little and thin aluminium alloy heat radiator, radiating effect is not enough again.
Summary of the invention:
At the deficiencies in the prior art, it is a kind of in light weight that the utility model provides, the led light source radiator of rapid heat dissipation.
The utility model comprises metallic matrix and radiating fin, is provided with porous metallic layers on the radiating fin surface of metallic matrix, constitutes quick passive radiator structure.
The utility model is the compound porous metallic layers that is provided with on radiating fin, and the area of dissipation of porous metals is big, the heat transfer efficiency height, and the density of distribute heat, and porous metals rapidly is low, can alleviate the weight of radiator greatly, improves radiating effect.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings:
Accompanying drawing is the main structure schematic diagram of embodiment.
Embodiment:
As shown in the figure, be provided with porous metallic layers 3, constitute quick passive radiator structure on radiating fin 2 surfaces of metallic matrix 1.Present embodiment adopts comb-type structure, and porous metallic layers 3 can use the metal level of foam metal or microcosmic porous, and 1 of metallic matrix can adopt easy heat conduction metal-based materials such as copper, aluminium or alloy to make.Porous metallic layers 3 generally is sintered combined radiating fin 2 surfaces at metallic matrix 1, or makes at surface deposition by electrochemical means.
Present embodiment is provided with heat conduction long fibre 4 in metallic matrix 1, heat conduction long fibre 4 is arranged evenly by heat dissipation direction.Heat conduction long fibre 4 general available carbon fibers, heat conduction is good, makes the faster guiding radiating fin 2 of heat.General led light source 5 all is to be encapsulated on the substrate 6, during use metallic matrix 1 bottom of substrate 6 and radiator is tightly touched to be connected, and generally need coat heat-conducting silicone grease, and the heat of led light source 5 is shed by radiator.In fact, some led light sources 5 also can encapsulate the bottom that is connected metallic matrix 1, constitute the integral type light source, and are like this that led light source and radiator is integrated, do not need substrate 6, directly heat conduction, radiating and cooling better effects if.
