Abstract
The utility model discloses a heat dissipation device of a LED light source, which has good heat dissipation performance. The heat dissipation device of the LED light source comprises a heat dissipation main body; a heat pipe receiver is positioned on the heat dissipation main body, at least one heat pipe is provided on the heat pipe receiver. The utility model has the beneficial effects that: the utility model adopts a mode combining the heat pipe dissipation with the metal material dissipation, the performance of heat conduction and heat dissipation can be greatly improved, thereby being particularly suitable for heat dissipation of the high power LED light source.
Description
Technical field
The utility model relates to the heat radiation field, relates in particular to a kind of heat abstractor of led light source.
Background technology
Along with the development of semiconductor lighting technology, LED gradually from traditional small-power to single high-power and integrated high-power development, yet LED has only at a certain temperature could operate as normal.LED power is high more, caloric value is just big more, and the heating of single great power LED and integrated great power LED is very concentrated, the radiator that the present metal material with perfect heat-dissipatings such as aluminium, copper that generally adopts is made, its heat-sinking capability is obviously not enough, because the volume of aluminium or copper radiator reaches 0.006m
3The time, increasing volume and area again and can not obviously reduce thermal resistance, this heat energy that LED is sent can not conduct and discharge timely, has had a strong impact on the work of LED.
The utility model content
Technical problem to be solved in the utility model provides a kind of heat abstractor of led light source, has good performance of heat dissipation.
The technical scheme that the utility model technical solution problem is adopted is: the heat abstractor of led light source, comprise the heat radiation main body, and described heat radiation main body is provided with heat pipe receiver, and described heat pipe receiver is provided with at least one heat pipe.
The beneficial effects of the utility model are: the mode that the utility model adopts heat pipe heat radiation to combine with the metal material heat radiation, heat conduction and heat dispersion improve greatly, are specially adapted to the heat radiation of high-power LED light source.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Described heat pipe 4 is provided with at least one fin 2.Described fin 2 preferably is enclosed within on the described heat pipe 4, as shown in figures 1 and 3.Among the embodiment 1, there are 12 fin 2 to be enclosed within on described 4 heat pipes 4 respectively in the left and right sides of heat pipe receiver 3.Described fin 2 adopts aluminium, copper or other heat radiation good metal material to make, and the effect of fin 2 is to increase the area that discharges heat energy, and heat energy can be discharged more quickly.
Heat energy for the ease of more rapidly and efficiently absorption LED 6, the vertical direction of the centre of heat radiation main body 1 is provided with through hole 5, heat pipe receiver 3 and LED 6 are arranged in the described through hole 5, preferably relatively near being arranged in the described through hole 5, embodiment 2 as shown in Figure 2, owing to do not have other medium in the middle of heat pipe receiver 3 and the LED 6, the heat energy overwhelming majority that LED 6 sends can be absorbed by heat pipe receiver 3 and be passed by heat pipe 4, has so just increased efficient of the present utility model.
Fig. 4 and Fig. 5 are embodiment 3 of the present utility model, adopt 8 discoid fin 2 to be enclosed within on 6 heat pipes 4, and 6 heat pipes 4 are evenly distributed in 8 discoid fin 2.
The utlity model has the advantage of heat conduction and perfect heat-dissipating, be specially adapted to the heat radiation of the above great power LED of input power 5W.
Though the utility model illustrates and describes by the reference preferred embodiment.But those skilled in the art should understand, and in the scope of claims, can do various variations on form and the details.
