Add new heat dissipation.The heat dissipation technology for being usually used in great power LED has passive fin heat dissipation, air-cooled, water cooling, thermoelectric cooling, surpasses
Thermally conductive Manifold technology etc..Passive fin heat dissipation is dissipated the heat to the air by increasing effective heat dissipation area；Air-cooled technology uses
Reinforce conduction and heat convection using the methods of cooling fin and fan combination, the suitable air blower of selection or fan；Water Cooling Technology
Heat is taken away in middle chip heat transfer water supply, the flowing of water；Thermoelectric cooling technology using semiconductor paltie effect system
It is cold, radiating fin is added to increase heat dissipation effect in hot end sometimes；Heat pipe be the sixties grow up have high thermal conductivity
The heat transfer element of performance, structure is simple, conducts heat quickly using the evaporation latent heat and the latent heat of condensation of liquid, super heat-conductive pipe
It is on this basis, to increase the microflute that can strengthen the heat exchange of superconduction low-grade fever intraductal working medium, make it have more preferably heating conduction.
And thermal conduction resistance, great power LED and heat dissipation dress of the super heat-conductive pipe when being applied to great power LED cooling, between heat pipe and fin
Thermal contact resistance between setting becomes the key factor for restricting heat dissipation effect.
Summary of the invention
For the heat dissipation problem for more preferably solving great power LED, it is super that the utility model provides a kind of great power LED fin-
Heat conducting pipe integral heat dissipation device increases in existing super heat-conductive pipe technical foundation and strengthens super heat-conductive pipe and external agency progress
The integrated fin of heat exchange.
Specific technical solution is as follows: a kind of great power LED fin-super heat-conductive pipe integral heat dissipation device, including U-shaped super
Heat conducting pipe (1), straight rectangular fin (2), bayonet unit (3).It is characterized by: straight rectangular fin is integrated with super heat-conductive pipe
Change manufacture.Straight rectangular fin (2) is located at U-shaped super heat-conductive pipe (1) condensation segment (4) two sides, and fin is equidistant, the uniform cloth of equal thickness
It sets, all fin heights are equal.To reduce air thermal resistance and thermal contact resistance, evaporator section (5) lower surface is horizontal polished surface, is applied
Smear argentiferous silicone grease (6) the closely connection therewith by great power LED (7) using bayonet unit afterwards.Radiator material is aluminium.
Compared with prior art, the utility model has the beneficial effects that super heat-conductive pipe is strengthened as good heat conductive material
The diabatic process of great power LED and external agency；Application continuum array fin eliminates the thermally conductive heat between fin and super heat-conductive pipe
Resistance, while making fin equalizing temperature, improve fin efficiency；Argentiferous silicone grease is smeared between radiator and great power LED (7)
(6) and using bayonet unit (3) connection it can reduce thermal contact resistance；Radiator material generally aluminium, it is light-weight and save at
This.

Specific embodiment
The present invention will be further described with reference to the accompanying drawing:
The utility model provides a kind of technical solution: a kind of great power LED fin-super heat-conductive pipe integral heat dissipation dress
It sets, including U-shaped super heat-conductive pipe (1), straight rectangular fin (2), bayonet unit (3).As shown in Fig. 1, straight rectangular fin (2)
Positioned at U-shaped super heat-conductive pipe (1) condensation segment (4) two sides, the equidistant gap of every group of fin is air flow channel, and air circulation simultaneously takes away wing
The heat of on piece.U-shaped heat pipe two sides are full symmetric, and all fin heights are equal.Condensation segment (4) two sides as shown in Fig. 2 fin
(2).To reduce air thermal resistance, it is horizontal polished surface that evaporator section (5) lower surface, which is bonded position with great power LED, smears argentiferous
Radiator is connect with great power LED to reduce thermal contact resistance using bayonet unit (3) after silicone grease.
Based on the invention, the transmittance process of high-power LED chip heat production are as follows: chip heat is successively passed to greatly by thermally conductive
Argentiferous silicone grease layer, the super heat-conductive pipe evaporator section smeared between power LED package structure, great power LED and radiator, evaporation
Working medium is heated in section is evaporated to gas, liquid is condensed into after gas reaches condensation segment, and heat is passed to by thermally conductive
Super heat-conductive pipe condensation segment outer wall, straight rectangular fin, rear straight rectangular fin transfer heat to external Jie by free convection
Matter.
Using the utility model, super heat-conductive pipe has excellent heating conduction, uses bayonet unit combination argentiferous silicone grease
Mode closely connects great power LED and radiator, substantially reduces the thermal contact resistance of the two, and straight rectangular fin and superconduction
Heat pipe integrated manufacture reduces this part thermal resistance of the two connection, improves heat transfer efficiency.
