Abstract

The utility model discloses an LED aluminum extrusion type heat pipe radiator. The LED aluminum extrusion type heat pipe radiator comprises a substrate, and fins and thermally-conductive copper tubes which are arranged on the substrate. Surfaces of the fins are provided with a plurality of grooves. An angle of 90 degrees is formed by the direction of the grooves and the fins. The portions in which the grooves are formed are arranged into the thermally-conductive copper tubes in a welding manner. The diameter of each thermally-conductive copper tube is in the range from 3mm to 10mm or the thermally-conductive copper tubes are flattened to be flat thermally-conductive copper tubes having a thickness of 2mm-8mm. According to the utility model, heat generated by a light source can be transferred to all of the fins rapidly through the thermally-conductive copper tubes, so the temperature difference between the fins can be reduced, the heat dissipation function of all of the fins can be effectively utilized, and advantages, such as simple and compact structure, good cooling efficiency, good temperature averaging performance, etc., can be realized.

Description

A kind of LED aluminium extruded type heat-pipe radiator

Technical field

The utility model relates to radiator product, is specially a kind of LED aluminium extruded type heat-pipe radiator.

Background technology

LED heat dissipation technology, is generally used and mostly is heat-conducting plate mode now, is the copper coin that a slice 5mm is thick, is in fact temperature-uniforming plate, and thermal source samming is fallen; Also have finned to dispel the heat, but weight is too large.Weight is very important on road lamp system, because street lamp is high, has 9 meters, if too heavy danger just increases, especially Yu may produce accident Dao Taiwan wind, earthquake.Following LED extensively enters behind street lamp field, heat radiation must be that adopting heat pipes for heat transfer heat radiation solves the situation that it is difficult that LED lamp dispels the heat better.

At present LED radiator great majority are not laid heat pipe, are applied on the light fixture of high wattage and cannot rapidly thermal source be led on fin, cause the radiator temperature difference large, and radiating effect is had a greatly reduced quality.

Utility model content

It is large that a kind of LED aluminium extruded type heat-pipe radiator has solved LED aluminium fin type heat-pipe radiator aluminium fin temperature contrast, can not give full play to the heat sinking function of each aluminium fin.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of LED aluminium extruded type heat-pipe radiator, comprise substrate, be located at fin and heat-conducting copper pipe on substrate, several grooves are offered on described fin surface, groove direction becomes 90 degree with fin, heat-conducting copper pipe is inserted with welding manner in the position of described fluting.

Further, described fin is located at wherein one side of substrate, and substrate another side is smooth plane.

Further, the material of described substrate is alloy aluminium or copper material, and fin material is alloy aluminium.

Further, to comprise diameter be the flat type heat-conducting copper pipe that 3mm-10mm or above-mentioned heat-conducting copper pipe flatten into thickness 2mm-8mm to described heat-conducting copper pipe.

From the above-mentioned description to the utility model structure, compared to the prior art, the utlity model has following advantage:

The heat that light source produces sees through heat-conducting copper pipe and passes to rapidly all fins, reduces fin temperature contrast, and the heat sinking function of all fins of more effective performance improves the radiating efficiency of aluminium fin, and simple and compact for structure, cooling efficiency is high, average temperature performance good.
