Abstract
The invention relates to a louvered copper aluminum composite phase change high-power radiator and belongs to the technical field of light-emitting diode (LED) high-power lighting. A heat pipe is arranged in the middle of the louvered copper aluminum composite phase change high-power radiator, a grooved aluminum pipe in close contact is sleeved outside the heat pipe, the lower portion of the heat pipe is connected with a copper aluminum combination flange, fins with louvered stamping openings are adopted in the radiator, 40-60 fins are embedded in a groove of the grooved aluminum pipe and evenly distributed on the excircle periphery of the grooved aluminum pipe in a radial mode. When heat of the heat pipe is transmitted to the heat dissipation fins, the heat can be dispersed into the air through a long strip notch on one protruded side of a long strip, air is heated to move upwards, vertical convection of cold and hot air is formed, and air movement is accelerated. The heat dissipation area of the heat dissipation fins with the louvered stamping openings is increased by 10%, the cost is reduced due to a thin thickness, and the louvered copper aluminum composite phase change high-power radiator is a major breakthrough in the technical fields of high-power radiator LED lamps.
Description
Technical field
The present invention relates to a kind of louvered copper aluminium composite phase-change high-power heat-dissipation device, 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, 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, it mainly comprises heat pipe and radiator, the centre of described radiator is provided with heat pipe, fluting aluminum pipe at a close contact of heat pipe overcoat, connect copper aluminium Ifold flange in the heat pipe bottom, described radiator adopts the fin of blinds punched openings, and 40-60 fin embeds in the groove of fluting aluminum pipe, becomes radial at the circumferential periphery of the aluminum pipe of slotting and is evenly arranged.
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, middlely forms 1-6 10 * 50 * 1.5 millimeters rectangular projection by punching press, is provided with rectangular notch in a side of rectangular projection.
The invention has the beneficial effects as follows: the centre of this louvered copper aluminium composite phase-change high-power heat-dissipation device is provided with heat pipe, fluting aluminum pipe at a close contact of heat pipe overcoat, connect copper aluminium Ifold flange in the heat pipe bottom, radiator adopts the fin of blinds punched openings, 40-60 fin embeds in the groove of fluting aluminum pipe, becomes radial at the circumferential periphery of fluting aluminum pipe and is evenly arranged.When the heat of heat pipe was transmitted on the radiating fin, in air, air was heated and moves up rectangular notch that can be by a rectangular protruding side, forms the up and down convection current of cold and hot air, accelerates Air Flow with dissipation of heat.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.
