Description

A kind of LED lamp heat-radiating device

Technical field

The utility model relates to a kind of LED lamp heat-radiating device.

Background technology

Most on the market at present LED light fixtures adopt die casting aluminium or extruded signing panel shell, because the great power LED heat is concentrated, only rely on the heat conductivility of aluminium that heat is evenly distributed on the radiator, cause heat can not smooth and easyly be dispersed into surrounding environment thus, so shorten the service life of entire product.Adopt the shell radiator, will greatly increase product weight.Partial L ED light fixture adopts the conventional lamp shell, and heat is concentrated can't distribute, and the temperature rise of LED internal junction will be shortened the service life of lamp pearl greatly.

The utility model content

The purpose of this utility model is the weak point that overcomes original technology, provides that a kind of overall thermal resistance is little, simple and practical, the LED lamp heat-radiating device of good heat dissipation effect.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this LED lamp heat-radiating device, it is characterized in that being provided with fastening fin, heat pipe, base plate and heat conductive pad, heat pipe, fastening fin, base plate weld together and constitute a heat radiation module, and heat conductive pad is installed on the heat radiation module base plate.

The utility model heat conductive pad is installed on the heat radiation module base plate by screw.

Heat pipe described in the utility model is a U type pipe, and heat pipe one end is fixedlyed connected with base plate and placed directly over the LED, and the heat pipe other end inserts and fastens in the fin.

Fastening fin thickness described in the utility model is 0.3mm to 0.8mm, spacing 4mm to 6mm, 23 to 34 of quantity.

The utility model advanced person's heat pipe for thermal conductivity technology, good heat dissipation effect.Fasten fin and be linked to be an integral body, make product have better intensity, heat radiation spacing and good structural strength, base plate and the thermal resistance that fastens between fin, the heat pipe are little, and heat passage is more smooth and easy.

Description of drawings

Fig. 1 is the schematic perspective view of the utility model embodiment.

Fig. 2 is the exploded perspective view of the utility model embodiment.

The specific embodiment

Referring to Fig. 1, Fig. 2, the utility model comprises fastening fin 1, heat pipe 2, base plate 3 and heat conductive pad 4, heat pipe 2, fastening fin 1, base plate 3 adopt welding procedures to make a LED module 5, and heat conductive pad 4 is sticked LED module 5 back sides, are locked on the heat radiation module base plate 3 with many screws 6.

The utlity model has following characteristics: 1, adopt advanced heat pipe for thermal conductivity technology, 4 " U " type heat pipe 2 one ends are imbedded in the base plate 3, be placed in directly over the LED, the other end fastens in the fin 1 by inserting, the heat that LED is distributed is distributed to rapidly by base plate 3 and heat pipe 2 and fastens on the fin 1, by the free convection effect heat is dispersed in the surrounding environment again.

2, fastening fin 1 employing thickness is 0.3mm to 0.8mm, spacing 4mm to 6mm, quantity 22-34 sheet, wherein 27 thickness of optimal case employing are 0.6mm, spacing is 5mm, material is that copper, aluminium fin fasten, and makes whole fin be linked to be an integral body, makes product have better intensity optimum heat radiation spacing and good structural strength.

3, adopt advanced solder technology, reduce base plate 3 and fasten fin 1, the thermal resistance between base plate 3 and the heat pipe 2 makes heat passage more smooth and easy.

4, shell adopts the chimney type structure.When LED worked, radiator began to generate heat and the air of circumference, and air begins upwards to flow under the promotion of heat, simultaneously with cold air by passage inspiration fin space, both sides, reach the chimney type heat passage.

5, the gap is appropriate between the waist shape louvre of aluminum component shell and the fin, can make air-flow unobstructed flow mistake, plays better free convection effect.

6, base plate of radiator 3 adopts the mode of engagement to realize location and spring pressuring plate realization heat radiation module quick change.

7, the hollow out design is adopted in the shell side, makes whole system have good draining and dirt eliminating function.

8, employing heat conductive pad structure can reduce the gap between aluminium base and the radiator, reduces thermal resistance, makes heat can import base plate swimmingly.

9, LED module 5, heat conductive pad 4, radiator three connect the screw fixing and locking that adopts many M2.5 to M4 that are evenly distributed, and can eliminate the air gap between heat conductive pad and aluminium base and the shell to greatest extent, reach good heat-conducting effect.

More than be the concrete enforcement under the technical solutions of the utility model framework, the simple deformation or the combination of every the utility model embodiment technical scheme and technical characterictic all should be thought to fall into protection domain of the present utility model.
