The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment provides a kind of heat abstractor, its planar structure schematic diagram as shown in Figure 2, perspective view is as shown in Figure 3.In conjunction with Fig. 2 and Fig. 3, described heat abstractor comprises copper base 1, induced draught fan 2, heat radiation aluminium fin 3, blowing fan 4.Described copper base 1 structure is the L type, is provided with the fixing hole 11 fixing with three-color light source at described copper base 1, referring to shown in Figure 3.Described copper base 1 passes described fixing hole 11 by screw fixedlys connected with the light source substrate (not shown), thereby three-color light source is fixed on the described copper base 1.Be coated with heat-conducting silicone grease or other heat-conducting medium materials between described copper base 1 and the described light source substrate.The quantity of described fixing hole 11 can be determined according to the design needs.
Because the thermal conductivity of copper itself is very high, therefore can obtain very high heat-transfer capability with very thin copper base, the heat of three light sources can be derived rapidly.In addition, can determine the shape of described copper base according to the distribution of three-color light source, the shape of described copper base is not limited to the L type structure among the utility model embodiment.Preferably, the thickness of described copper base is 1.5 ~ 5mm.
The application of described copper base has solved the part heat dissipation problem, the heat in the described three-color light source is stored in the copper base, but heat accumulation can't loose on copper base still and to solve the problem of heat radiation fully.For this reason, referring to shown in Figure 4, on described copper base 1, directly weld intensive heat radiation aluminium fin 3, described heat radiation aluminium fin 3 thickness are 0.2 ~ 0.3mm, spacing is 1 ~ 2mm between every, and thin heat radiation aluminium fin takes up room less, so the sheet number of welding is more, increase area of dissipation so greatly, be convenient to better heat radiation.By welding manner described heat radiation aluminium fin 3 is fixed on the described copper base 1, thermal resistance between described copper base 1 and the described heat radiation aluminium fin 3 is very little, the heat of described copper base 1 is transferred to rapidly on the huge heat radiation aluminium fin 3 of area, be dispersed on the larger area heat radiation aluminium fin 3 by the heat conduction to the heat of this light source, blow in the atmosphere outside the casing by will dispel the heat heat on the aluminium fin 3 of two fans more at last.
