Abstract
The utility model relates to an LED (Light Emitting Diode) radiator, belonging to the technical filed of structural parts of electric equipment. The LED radiator consists of an aluminum-based circuit board, an LED fixed at the top surface of the aluminum-based circuit board, and a micro heat pipe, one end of the micro heat pipe is fixed on the bottom surface of the aluminum-based circuit board, the other end of the micro heat pipe is connected with at least one group of radiating fins, each radiating fin is rectangular, and chamfers are arranged at four angles of the rectangle of the each radiating fin. The LED radiator has the advantages of effectively radiating heat generated by the LED.
Description
Technical field
The utility model relates to a kind of micro heat pipe that utilizes to the device that LED dispels the heat, and belongs to the structure parts technical field of electric equipment.
Background technology
Along with the development of LED, LED is owing to characteristics such as energy-saving and environmental protection, long working life enjoy the concern of all circles, the extensive use of LED oneself through becoming kind of a development trend.
Because high-powered LED lamp in the course of the work, except that luminous, produce a large amount of heats simultaneously, and the height of LED junction temperature (chip temperature) directly influences the life-span of light fixture.Therefore, high-powered LED lamp need produce great amount of heat when luminous derives.
The utility model content
The technical problem that the utility model will solve is not enough to prior art, proposes the heat abstractor that a kind of heat that LED is produced carries out efficiently radiates heat.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of LED heat abstractor; Comprise aluminium base circuit board and be fixed on the LED on the aluminium base board top surface; Also comprise micro heat pipe, an end of said micro heat pipe is fixed on the aluminium base circuit board bottom surface, and the other end of said micro heat pipe is connected with at least one group of fin; Said fin is a rectangle, and four angles of the rectangle of said fin are shaped on chamfering.
The improvement of technique scheme is: also be fixed with the micro heat pipe mount pad on the said aluminium base circuit board bottom surface, be shaped on the installing hole that is used to install micro heat pipe on the said mount pad.
The improvement of technique scheme is: said micro heat pipe and installing hole are interference fits.
The improvement of technique scheme is: the coiled pipe that is connected with cryogenic fluid in being equipped with on the said fin.
The improvement of technique scheme is: also comprise the fan that is arranged at the fin place.
The beneficial effect that the utlity model has is: 1) owing to used micro heat pipe; Use the fin of rectangle simultaneously, further be shaped on chamfering at four angles of the rectangle of fin, the heat that can LED be produced absorbs through an end of micro heat pipe; Be transported to fin; Heat is taken away by air through fin heat conduction and free convection at last, and the heat that effectively LED is produced dispels the heat; 2) because the micro heat pipe mount pad is set, micro heat pipe is fixed on the mount pad installing hole simultaneously, can be so that the heat that LED produces transmits through micro heat pipe more fully; 3) owing to being connected with the coiled pipe of cryogenic fluid in being equipped with on the fin and being equipped with in the fan at fin place, the strong convection through coiled pipe or fan form better dispels the heat.
Description of drawings
Below in conjunction with accompanying drawing being described further to the utility model.
Fig. 1 is the structural representation of the utility model embodiment LED heat abstractor.
Embodiment
Embodiment
The LED heat abstractor of present embodiment, as shown in Figure 1, comprise aluminium base circuit board 1 and be fixed on the LED2 on aluminium base circuit board 1 end face, also comprise micro heat pipe 3.
One end of micro heat pipe 3 is fixed on aluminium base circuit board 1 bottom surface, and the other end of micro heat pipe 3 is connected with at least one group of fin 4.Fin 4 is rectangles, and four angles of the rectangle of fin 4 are shaped on chamfering 4-1.
Also be fixed with micro heat pipe mount pad 5 on aluminium base circuit board 1 bottom surface of present embodiment, be shaped on the installing hole that is used to install micro heat pipe on the mount pad 5.
The micro heat pipe 3 and the installing hole of present embodiment are interference fits.
Be connected with the coiled pipe 6 of cryogenic fluid in can also being equipped with on the fin 4 of present embodiment.
Present embodiment can also be provided with fan 7, and fan 7 is arranged at fin 4 places.
During use; The heat that LED2 produces is transferred on the micro heat pipe 3 through micro heat pipe mount pad 5, and micro heat pipe 3 is transported to fin 4 with heat, and heat is through fin 4 heat conduction and free convection; Taken away by air at last, the heat that effectively LED2 is produced dispels the heat.
Simultaneously, perhaps pass through to start fan 7, form strong convections, better dispel the heat through fan 7 through the coiled pipe 6 that is connected with cryogenic fluid in being equipped with on the fin 4.
The utility model is not limited to the foregoing description, and for example, micro heat pipe 3 can adopt two and more.All employings are equal to the technical scheme that replacement forms, and all drop on the protection range of the utility model requirement.
