Abstract
The utility model discloses a double-light-source heat-dissipation module which comprises a base plate, heat-dissipation fins and U-shaped heat-conducting pipes. Multiple installing grooves are formed in the base plate at intervals, one end of each U-shaped heat-conducting pipe is fixed in the corresponding installing groove in the base plate, and the other end of each U-shaped heat-conducting pipe is arranged radially. The heat-conducting pipes are sleeved by the heat-dissipation fins, the heat-dissipation fins are provided with a plurality of heat-dissipation holes, and the lower surface of the base plate is provided with double high-power LED light sources. In the double-light-source heat-dissipation module, the heat-conducting pipes and the installing grooves of the base plate are connected and fixed in a tight-match mode, and the heat-dissipation fins and the heat-conducting pipes are connected and fixed in a tight-match mode, so that the problem that welding is required previously is solved, existing surface nickel plating and other processes are also omitted, the production efficiency is greatly improved, and no pollution is produced in the production process. Lamps can be conveniently replaced by adopting rapid waterproof connector terminal connecting lines, and the maintenance time is saved. By adopting stainless steel waterproof connectors, the overall sealing performance is ensured, water does not easily flow into the lamps, the service life of the lamps is prolonged, and the potential safety hazard is reduced.
Description
Technical field
The utility model relates to light source heat radiation module, especially relates to a kind of pair of light source heat radiation module, and relating to specifically a kind of is the heat radiation module of 100W LED lamp module towards two light sources and single source.
Background technology
Development along with semiconductor technology, great power LED is more and more wider in the application of lighting field, because only having at a certain temperature, high-power LED light source could normally work, so must consider the heat dissipation problem of great power LED, only the junction temperature of guaranteed great power LED is no more than certain scope, just can guarantee the life-span of light source.The radiator that the metal material of the good heat dispersion performance such as the aluminium adopting at present or copper is made, its heat-sinking capability is obviously not enough, because the volume of aluminium or copper radiator reaches 0.006m
3time, then increase volume 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 large, making LED light source send can not effectively conduct simultaneously, has a strong impact on the normal work of LED light fixture.
Along with the development of LED technology, also developed high-power LED light source module, although the application of high-power LED light source module has solved the problem of area occupied,, its caloric value also can increase along with the increase of power.So, development along with high-power LED light source module, the power of encapsulation is more and more higher, but the structure of light fixture requires compactness, this just makes the heat dissipation problem of chip seem especially outstanding, and the heat conduction efficiency of single radiating fin is low, the heat of LED chip can not be transmitted on radiating fin fast, thereby cause LED chip to occur heat accumulation, temperature raises, and affects the service life of LED.Therefore only use single radiating fin cannot meet the radiating requirements of high-power LED illumination product.
Summary of the invention
The purpose of this utility model is for the deficiency in above-mentioned technology, and strong, the easy installation of a kind of heat-sinking capability, the stable two light source heat radiation modules of radiating effect are provided.
The purpose of this utility model is achieved through the following technical solutions:
A pair light source heat radiation module, comprises base plate, radiating fin and " U-shaped " heat pipe, and described plate upper surface is spaced apart is provided with a plurality of mounting grooves, and one end of heat pipe is fixed in the mounting groove of base plate, and the other end is arranged radially; Described radiating fin is sleeved on heat pipe, and described radiating fin is provided with several louvres; The lower surface of described base plate is provided with the two light sources of great power LED; On described base plate, be also provided with line outlet, described line outlet is provided with stainless steel water joint, and what be connected with described stainless steel water joint coupling is rapidity water joint terminal connecting line.
The number of described heat pipe is at least 8, is preferably 8.
The number of described radiating fin is at least 60.
The thickness of described radiating fin is 0.2-0.5mm.
Gap between described adjacent radiating fin is 1-3mm.
Described heat pipe and mounting groove are that tight fit connection is fixed.
Described radiating fin is provided with installing hole, and described heat pipe is fixed by suit hole and radiating fin tight fit connection.
