Abstract
The utility model discloses a circulation heat tube radiator for an LED lamp. The radiator comprises a heat collector baseplate, a plurality of radiating sheets and a plurality of circulation heat tubes, wherein, the plurality of radiating sheets are arranged on the upper surface of the heat collector baseplate, each circulation heat tube forms a closed circulation loop cavity, by adopting the expansion technology, the lower end of each circulation heat tube is closely connected with a rib wing at the upper end of the heat collector baseplate, and the upper end of each circulation heat tube is closely connected with each radiating sheet through a heat tube hole on the radiating sheet. The utility model has the advantages of small heat resistance, quick heat absorption, quick heat transfer and high radiating efficiency. Moreover, the circulation heat tube radiator has the advantages of small volume, light weight, good anti-corrosion capability and notable effect, requires neither power nor maintenance, is convenient to assemble and reliable in operation, and is particularly suitable for lighting in regions with strong wind and harsh environment.
Description
Technical field
The utility model relates to a kind of LED light fixture radiator.
Background technology
The radiating mode of LED light fixture use at present is a lot, mainly be to adopt the extruded aluminium of different shape to make radiator, though the radiating effect of aluminium is pretty good, because the brightness of illumination requirement is more and more higher, the power requirement of light fixture is increasing, used great power LED is more and more, and especially integrated optical source requires more and more higher for heat radiation, the thickness and the volume of extruded aluminium are increasing, light fixture is more and more heavier, not only is not easy to install, and more and more higher to the requirement of lamp stand.In order to alleviate the weight of radiator, strengthen radiating efficiency, the gravity assisted heat pipe radiator has appearred on the market, aluminum slice and gravity assisted heat pipe are fixed together but this kind radiator employing crimp technology will be dispelled the heat, the gravity assisted heat pipe thermal resistance is big, heat transfer is slow, radiating efficiency is low, still can not reach more and more higher heat radiation requirement.
Summary of the invention
The utility model solves the above-mentioned problems in the prior art exactly, provides a kind of thermal resistance little, and it is fast to conduct heat, the radiating efficiency height, and volume is less, the LED light fixture circulating hot-pipe radiator that weight is light, the heat pipe life-span is long.
For addressing the above problem, technical solution of the present utility model is: a kind of LED light fixture circulating hot-pipe radiator, and it comprises heat collector substrate, multi-disc heat radiation thin slice and Duo Gen circulating hot-pipe; Multi-disc heat radiation thin slice place the heat collector substrate above, the heat pipe hole that interconnects is arranged on it; Every circulating hot-pipe forms an airtight circulation loop die cavity, and the lower end of every circulating hot-pipe adopts expansion technique closely to be connected with the rib wing of heat collector substrate upper end, and the upper end adopts expansion technique closely to be connected by the heat pipe hole on the heat radiation thin slice with the heat radiation thin slice.
Above-mentioned described heat radiation thin slice is an aluminum heat radiation thin slice, and the heat collector substrate is an aluminum heat collector substrate.
The two sides of above-mentioned described heat radiation thin slice is all uneven, one side projection, and another side is recessed, also has louvre above, and a slice concave surface of two adjacent heat radiation thin slices is to the convex surface of another sheet, relatively arranged in dislocation.Like this, not only increased the area of dissipation of heat radiation thin slice, and the external force extruding can not cause the distortion of fin, the non-deformability of fin is strong, and ventilation effect is good.
The utility model adds circulating hot-pipe in heat radiating metal, after the heat that LED produces is collected by the heat collector substrate, circulating hot-pipe can conduct heat to rapidly on the heat radiation thin slice, directly is transferred in the air by the heat radiation thin slice, and its thermal resistance is little, heat absorption is fast, it is fast to conduct heat, radiating efficiency is high.The utility model is easy to assembly, and volume is little, and is in light weight, and antiseptic power is good, need not power, need not safeguard, reliable, effect is remarkable, is specially adapted to high wind, the abominable area illumination use of environment.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a vertical view of the present utility model;
Fig. 3 is a left view of the present utility model.
The specific embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is further described:
As Fig. 1, Fig. 2 and shown in Figure 3, present embodiment comprises aluminum heat collector substrate 5, multi-disc aluminum heat radiation thin slice 1 and four circulating hot-pipes 3.Multi-disc aluminum heat radiation thin slice 1 place heat collector substrate 5 above, the heat pipe hole 2 that interconnects is arranged on it.Every circulating hot-pipe 3 forms an airtight circulation loop die cavity, adopt expansion technique, the lower end of every circulating hot-pipe 3 closely is connected with the rib wing 4 of aluminum heat collector substrate 5 upper ends, and the upper end closely is connected with aluminum heat radiation thin slice 1 by the heat pipe hole 2 on the aluminum heat radiation thin slice 1.The two sides of aluminum heat radiation thin slice 1 is all uneven, the one side projection, and another side is recessed, also has the convex surface of a slice concave surface of 6, two adjacent heat radiation thin slices 1 of louvre to another sheet above, relatively arranged in dislocation.Heat collector substrate 5 in the present embodiment and heat radiation thin slice 1 also the metal of copper or silver or other good heat conduction effect make.
Certainly; the utility model also has other multiple example; under the situation of the utility model spirit and essence; those of ordinary skill in the art can make corresponding change and distortion according to the utility model; but these corresponding changes and distortion all should belong to the improvement of equivalent technologies, belong to the protection domain of the utility model claim.
