Abstract
The utility model discloses a high-power LED cooling module which comprises a light source back panel, a cooling section material, at least one heat conducting pipe and at least two cooling fins, wherein the bottom part of the cooling section material is arranged on the light source back panel, one end of the heat conducting pipe penetrates through the bottom part of the cooling section material and is connected with the light source back panel, all the cooling fins are sheathed on the heat conducting pipe, the cooling surface of each cooling fin is provided with a plurality of bosses, the high-power LED cooling module adopts a mode combining the method adopting the heat conducting pipe connected with the cooling fins for cooling with the method adopting metal materials for cooling, and a plurality of cooling fins are prevented from being contacted mutually when being installed by the bosses on the cooling surfaces, thus improving the cooling stability, greatly improving the cooling performance of the cooling device, and reducing the potential safety hazard.
Description
Technical field
The utility model relates to a kind of heat radiation module, especially adopts heat pipe to connect the dispel the heat heat radiation module of the high-power LED light source that combines of fin heat radiation and metal material, specifically a kind of great power LED cooling module.
Background technology
Along with development of semiconductor, great power LED is more and more wider in the application of lighting field, because high-power LED light source has only at a certain temperature could operate as normal, so must consider the heat dissipation problem of great power LED, only the junction temperature of guaranteed great power LED can not surpass certain scope, the life-span that just can guarantee light source.The radiator that the metal material of good heat dispersion performance such as present aluminium that adopts or copper is made, its heat-sinking capability is obviously not enough, because when the volume of aluminium or copper radiator reaches 0.006m3, increase volume again and can not obviously reduce temperature, and can increase the weight of aluminium or copper radiator, strengthen light fixture weight, make light fixture overweight, potential safety hazard is big, and making led light source send simultaneously can not effectively conduct, and has a strong impact on the operate as normal of LED light fixture.
Chinese patent 200920208257.0 discloses " a kind of heat abstractor of LED street lamp ", comprise and be arranged on the heat-conducting substrate and the heat radiation main body that is connected heat-conducting substrate that is used for heat conduction under the LED lamp array, the heat radiation main body comprises that at least one heat pipe that connects heat-conducting substrate and at least one are enclosed within the fin on the heat pipe, heat pipe is the airtight copper pipe of inner hollow, this copper pipe inside is network structure, and condensate liquid is housed.The mode that this device utilizes the heat radiation of heat pipe heat radiation and metal material to combine, heat conduction and heat dispersion improve greatly, but the fin of this heat abstractor is when installing, owing to there is not positioner, hold by artificial, be in contact with one another when occurring installing easily, influence radiation stability.
Summary of the invention
The utility model provides strong, the easy installation of a kind of heat-sinking capability, the stable great power LED cooling module of radiating effect just in order to overcome above-mentioned deficiency.Main innovation is on the radiating surface of fin boss to be set, with this boss spacing as between each fin.
It specifically is to implement like this: a kind of great power LED cooling module, comprise light source backboard, heat sink section bar, at least one heat pipe and at least two fin, described heat sink section bar bottom is installed on the light source backboard, one end of heat pipe passes the heat sink section bar bottom and is connected with the light source backboard, each fin all is sleeved on the heat pipe, it is characterized in that being equipped with several boss on the radiating surface of fin.Heat pipe conducts out fast with the heat of heat-radiating substrate, sheds by the mode of the fin around it with conduction and convection current again.The one or more boss that are provided with on the radiating surface of fin can prevent that a plurality of fin are in contact with one another when mounted, and the mutual alignment of fin is fixed, and improve radiation stability.
In order to finish the heat transmission better, the radiating surface of the utility model fin is provided with the flange hole that cooperates suit with heat pipe, closely cooperates with the quick conductive pipe, the temperature of heat-radiating substrate is received, and fast heat is passed by surface area.Also have louvre on the radiating surface of fin, more help the diffusing of heat and remove.
The obturator that heat sink section bar of the present utility model is made up of the pedestal that is " Qian " type, two side seal boards and cover plate, pedestal two outsides of " Qian " type are equipped with the radiating fin of parallel installation, cover plate inserts in the connection hole slot that turns in the pedestal top of " Qian " type, and the slotted eye that the bottom of two side seal board inboards is provided with on boss and " Qian " type pedestal connects.
In order more to help heat radiation and to ventilate, have the hole of shutter or arrangement on two side seal boards of the utility model heat sink section bar.
Heat pipe of the present utility model is a U-shaped, and its cross section is circle, taper shape or flat etc.
Fin of the present utility model is circular, semicircle, square, camber line shape, triangle or pentalpha etc.
The beneficial effects of the utility model: the utility model adopts heat pipe to connect the mode that the fin heat radiation combines with the metal material heat radiation, prevent that with the radiating surface boss a plurality of fin are in contact with one another when mounted, improved radiation stability, make the heat dispersion of heat abstractor obtain big lifting, reduced potential safety hazard.
