Description

High heat radiating fin chip radiator

Technical field

The utility model relates to the heat sink technology field, especially a kind of high heat radiating fin chip radiator.

Background technology

LED has the advantage of energy-saving and environmental protection, has become main trend in the development of light fixture industry, is widely used in fields such as automobile, traffic lights indication at present; The Along with people's growth in the living standard, to the power of LED lamp require increasingly highly, but that the problem that high-capacity LED brings is heat radiation is difficult; In order heat in time to be distributed and not influence luminous quality and life-span, traditional method is a plurality of fins that on the pedestal of radiator, distribute, and the heat that LED produces exhales through fin; This radiator is because its material and design factor often make that the thickness of fin is bigger, and it is tabular mostly fin is; Area of dissipation is limited, thereby radiating efficiency is not high, on the other hand; Present radiator is in the assembling process of fin; The corners that fin often occurs scratches workman's problem, and it is simple again therefore how to design a kind of assembling safety, and the radiator that radiating efficiency is high again is a technical barrier that needs to be resolved hurrily in the present industry.

The utility model content

The technical problem that the utility model will solve is: in order to solve the problem that is prone to scuffing in the prior art in the radiator assembling process, a kind of simple high high heat radiating fin chip radiator of radiating efficiency of safety again that assembles is provided.

The utility model solves the technical scheme that its technical problem adopted: a kind of high heat radiating fin chip radiator; Comprise pedestal, last soaking plate, following soaking plate and heat pipe heat; Said pedestal is a tubulose, and base internal wall is installed heat pipe heat, and the said soaking plate that goes up is fixedly mounted on respectively on the two ends mouth of pipe of pedestal with following soaking plate; Circumferential divergence expression is evenly distributed with the polylith fin on the outer tube wall of said pedestal; The both ends of said fin have flanging, and said flanging is connected with following soaking plate contact with last soaking plate respectively, is coated with bound edge on the corners of said fin.

In order to improve area of dissipation, obtain better radiating efficiency, said fin is provided with a plurality of convexities, and said convexity is recessed to form by an another side towards fin of fin.

For obtaining better radiating effect, the convexity on said each fin identical towards all, the distributing position of said convexity on fin is all identical with distributed quantity.

As preferably, said fin and pedestal outer tube wall are welding.

Have socket and buckle ear on the flanging of said every fin, two adjacent fins are through buckle ear and socket snapping.

The beneficial effect of the utility model is that the high heat radiating fin chip radiator of the utility model has following effect with respect to the traditional heat-dissipating device:

1), multistage heat radiation, efficient is high: the heat that thermal source produces can conduct to fin through upper and lower soaking plate and dispel the heat, and also can conduct to fin through pedestal and dispel the heat;

2), radiating surface is big: through on the plate face of fin, increasing a plurality of convexities, strengthened the area of dissipation of fin, the mechanism of this male and fomale(M&F) has strengthened radiating efficiency; In the fin corners bound edge is installed, has been strengthened this place's intensity on the one hand, also increased area of dissipation on the other hand, thereby also improved radiating efficiency.

3), easy for installation, can prevent industrial injury: coat one deck bound edge in the fin corners, this bound edge is smooth, does not have sharp position, has prevented the problem that the workman is prone to be scratched when assembling, and has guaranteed workman's health safety.

Embodiment

Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.

The structural representation of the specific embodiment of the high heat radiating fin chip radiator of the utility model shown in Fig. 1 ~ 3 comprises pedestal 1, last soaking plate 2, following soaking plate 3 and heat pipe heat 4, and pedestal 1 is a tubulose; Pedestal 1 inwall is installed heat pipe heat 4; Last soaking plate 2 is fixedly mounted on respectively on the two ends mouth of pipe of pedestal 1 with following soaking plate 3, and circumferential divergence expression is evenly distributed with polylith fin 5 on the outer tube wall of pedestal 1, and fin 5 is welding with pedestal 1 outer tube wall; The both ends of fin 5 have flanging 51; 3 contacts are connected flanging 51 with following soaking plate with last soaking plate 2 respectively, and fin 5 is provided with a plurality of protruding 52, and convexity 52 another sides towards fin 5 by fin 5 are recessed to form; Be coated with bound edge 53 on the corners of fin 5; This bound edge 53 has increased area of dissipation and this place's intensity on the one hand, has made things convenient for workman's assembling on the other hand, and fail safe is improved; For obtaining better radiating effect, the convexity 52 on each fin 5 identical towards all, protruding 52 distributing positions on fin 5 are all identical with distributed quantity.

Protruding 52 effect is that the area of dissipation of fin 5 has been strengthened, thereby radiating efficiency increases, and thisly in addition on fin 5, arranges orderly convexity 52, has also played the perturbation action to air-flow, also is to have strengthened radiating effect to a certain extent.
