Abstract
The invention relates to an LED (light-emitting diode) lamp with a louvered copper-aluminum composite phase-change high-power radiator, belonging to the technical field of LED high-power illumination. The LED lamp with the louvered copper-aluminum composite phase-change high-power radiator comprises a power supply, an LED chip and a radiator. A heat pipe is arranged in the middle of the radiator. A grooved aluminum pipe which is in close contact with the heat pipe is sheathed outside the heat pipe. The LED chip is installed on a copper-aluminum composite flange at the lower part of the heat pipe. The power supply at the upper part of the heat pipe is arranged between a power supply box upper cover and a power supply box lower cover. The radiator consists of louver punched open fins. Forty to sixty fins are embedded into the circumferential grooves of the grooved aluminum pipe and are radially and evenly arranged on the outer circumference of the grooved aluminum pipe. When heat of the heat pipe is transferred to the radiating fins, the heat can be dissipated into air through four rectangular notches on each fin, the air is heated and moves upwards, cold air and hot air convectively flow up and down and the air flowing is accelerated. By using the louver punched open radiating fins, the radiating area is increased by 10 percent, the cost is low because the fins are thin, and an important progress is made in the technical field of LED lamps with high-power radiators.
Description
Technical field
The present invention relates to a kind of louvered copper aluminium composite phase-change high-power heat-dissipation device LED lamp, belong to LED high-power illumination technical field.
Background technology
In the prior art, it is little that LED integrated optical source has a volume, and the advantages such as simple are installed.But the LED light source applications of integration packaging fails effectively to be solved in the light decay problem of high-power illumination light fixture always at present, its main cause is that chip package is on the less support of area, the heat that moment is gathered can't in time be derived, wearing out appears in fluorescent material and the elargol that causes light source that work long hours, thereby affects the delivery efficiency of light.The radiating fin of common LED radiator is all extruded integral type, owing to be subjected to the restriction of expressing technique, causes the thickness of radiating fin thicker, and area is less, causes radiating effect relatively poor, and manufacturing cost is too high.And the desirable designing requirement of LED high-power heat-dissipation device is to adopt lower manufacturing cost, and should obtain optimal radiating effect.And existing extruded type LED radiator does not possess this two characteristics.
Summary of the invention
All be to extrude the problem that exists in the integral type in order to overcome above-mentioned existing LED radiator heat pipe and fin, the invention provides a kind of louvered copper aluminium composite phase-change high-power heat-dissipation device LED lamp, this LED lamp should have good radiator structure, the layout of compactness and profile attractive in appearance.
The present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of louvered copper aluminium composite phase-change high-power heat-dissipation device LED lamp, it mainly comprises power supply, led chip and radiator, the centre of described radiator is provided with heat pipe, fluting aluminum pipe at a close contact of heat pipe overcoat, copper aluminium Ifold flange in the heat pipe bottom is installed led chip, top is provided with power supply, described radiator adopts the fin of blinds punched openings, 40-60 fin embeds in the circumferential slot of fluting aluminum pipe, circumferential periphery at the fluting aluminum pipe becomes radial and is evenly arranged, and described power supply is arranged between power pack loam cake and the power pack lower cover.Described copper aluminium Ifold flange adopts heat pipe copper flange and aluminium flange to be fixed together.
Be provided with superconducting fluid in the inner chamber of described heat pipe.
Described fin adopts 100 * 86 * 0.9 millimeter fin, the middle rectangle gap that forms 1-6 10 * 50 * 1.5 millimeters by punching press.
Be covered with convex lens on the described led chip.
The downside of described aluminium flange is provided with a lamp umbrella.
The invention has the beneficial effects as follows: this louvered copper aluminium composite phase-change high-power heat-dissipation device LED lamp comprises power supply, led chip and radiator, centre at radiator is provided with heat pipe, fluting aluminum pipe at a close contact of heat pipe overcoat, copper aluminium Ifold flange in the heat pipe bottom is installed led chip, and the power supply on top is arranged between power pack loam cake and the power pack lower cover.Radiator adopts the fin of blinds punched openings, and 40-60 fin embeds in the circumferential slot of fluting aluminum pipe, becomes radial at the circumferential periphery of the aluminum pipe of slotting and is evenly arranged.When the heat of heat pipe is transmitted on the radiating fin, can by 4 rectangle clearance aperture with dissipation of heat in air, air is heated and moves up, and forms the up and down convection current of cold and hot air, accelerates Air Flow.This blinds punched openings radiating fin, area of dissipation has increased by 10%, thinner thickness reduction cost, be an important breakthrough in the high-power heat-dissipation device LED lamp technical field.
