Description

Used for large power LED lamp Combined heat pipe radiator

technical field:

The utility model belongs to heat pipe heat radiation equipment, refers to especially a kind of heat-pipe radiator of high-powered LED lamp heat transmission.

background technology:

High-powered LED lamp is because caloric value is large, very low with fin or aluminium radiator radiating efficiency, causes heat to pile up in die sites, and the chip operation life-span is reduced greatly.The heat radiation of employing heat-pipe radiator, efficiency can greatly improve, particularly for the LED lamp (200W-500W) of super high power, the advantage of heat pipe heat radiation is more obvious, but how to impel the working medium in heat pipe more effectively to circulate, to reach the object of rapid heat radiation, just need to carry out effective Combination Design to existing heat pipe circulation line, otherwise, be also difficult to solve the heat dissipation problem of superhigh power LED lamp.

utility model content:

Technical problem to be solved in the utility model is that a kind of used for large power LED lamp Combined heat pipe radiator will be provided, and greatly improves heat pipe heat radiation efficiency, can solve the heat dissipation problem of the above superpower LED of 200W lamp, to improve the LED chip life-span, reduces light decay.

Overall technology design of the present utility model is:

Used for large power LED lamp Combined heat pipe radiator, comprise the box-like evaporation cavity of hollow, evaporation tube and return duct, on evaporation tube and return duct with many branched pipes, every branched pipe extension is coiled into single or multiple lift heat pipe circulation line, the head end of every branched pipe is connected with evaporation tube, and end is connected with return duct.

Every branched pipe forms a set of independently heat pipe circulation line, is finally combined into the many covers heat pipe closed circulation pipeline that shares a box-like evaporation cavity of hollow.

On the box-like evaporation cavity of hollow, can be connected with one or more evaporation tube and return duct.

LED light source chip installing hole, with rectangle solid aluminum block, can be reserved in the box-like evaporation cavity of hollow both sides.

Concrete measure of the present utility model is:

Branched pipe on evaporation tube is extended and is coiled into single or multiple lift heat pipe circulation line, then branched pipe end is connected with return duct, branched pipe is connected with evaporation tube and return duct, can be shell and tube, also can be dispergated, or other shape, forming branched structure, a branched structure is exactly a single cover heat-pipe radiator.

The technological progress that the utility model is obtained is:

By the branched structure on evaporation tube, return duct, can make heat be diffused into rapidly in many cover heat pipe closed circulation pipelines, to reach the effect of rapid heat radiation.

By the branched structure on evaporation tube and return duct, form relatively independent heat pipe circulation line, can, according to the combination of different LED lamp power designs, be convenient to suitability for industrialized production.

In the utility model, Reference numeral is as follows:

1, the box-like evaporation cavity of hollow; 2, evaporation tube; 3, return duct; 4, solid aluminum block;

5, installing hole; 6, branched pipe; 7, the head end of branched pipe; 8, the end of branched pipe;

9, radiating wire.

the specific embodiment:

Below in conjunction with accompanying drawing, embodiment of the present utility model is described further; but conduct is not to restriction of the present utility model; the content that protection domain of the present utility model is recorded with claim is as the criterion; any equivalence techniques means of making according to this description are replaced, and all do not depart from protection domain of the present utility model.

As shown in Figure 1, Figure 2, Figure 4 shows, the box-like evaporation cavity 1 of hollow is welded to connect to one or more evaporation tube 2 and one or more return duct 3, the box-like evaporation cavity of hollow 1 both sides, with rectangle solid aluminum block 4, are reserved with LED light source chip installing hole 5 above.As shown in Figure 3, a single tube is coiled into spiral single or multiple lift pipeline, forms branched pipe 6, be welded with radiating wire 9 above, single cover heat-pipe radiator.Again as shown in Figure 1, Figure 2, shown in Fig. 4, the head end of each branched pipe 67 is communicated with evaporation tube 2 welding, the end 8 of branched pipe 6 welds and is communicated with return duct 3, formation circulation line.After every cover heat-pipe radiator is all communicated with evaporation tube and return duct welding, form one, as shown in Figure 5: share a box-like evaporation cavity of hollow, evaporation tube and return duct be all with branched structure, with the Combined heat pipe radiators of many cover heat-pipe radiators combination.
