Description

A kind of efficient LED Radiator

Technical field

The utility model belongs to heat sink technology field, is specifically related to a kind of radiator for LED.

Background technology

nullIt is known that，So-called LED refers to light emitting diode，LED light source is as a kind of new type light source being widely used at present and quickly growing，Have energy-conservation compared with conventional light source、Efficiently、Volume is little、Life-span is long、Fast response time、Driving voltage is low、The advantages such as shock resistance is remarkable，It is thus possible to develop expansion industry size rapidly、Market share，Industry tendency leads under，Its technology is also being constantly updated and in-depth，But the maximum technology barriers that govern LED light source development at present are exactly the heat transfer of LED encapsulation and hot settlement issues，The heat dissipation problem of i.e. LED，LED is as light source，Generally it is required for long continuous firing，For this cold light source of LED，Work also can produce substantial amounts of thermal accumlation for a long time，This just requires that the radiator operating efficiency of LED light source is good，Can go to dredge heat energy by shorter pathway，Reduce the too high infringement brought to chip of temperature as far as possible，Current way is LED chip to be encapsulated on heat sink fall main support，Then heat sink fall main support is installed and be fixed on a large-scale radiating element，Such as heat-radiating substrate，Or aluminum base plate，Fixing connection between heat sink fall main support and radiating element realizes typically by two ways，The first is via heat-conducting cream transfer of heat，It two is that practical tin cream is by the way of reflow soldering transfer of heat，And most importantly the technique of both modes all is connected between radiator to produce high temperature in LED chip，Easily hurt LED chip，Luminous flux is caused to decline，LED encapsulation structure is damaged，Electrical parameter changes，Light decay increases severely.

In general, in industry, traditional radiator typically designs according to concrete applicable cases, size is relatively fixed, and versatility is poor, and some producer is to use small-sized fans forced heat radiation for the radiating mode of LED at present, the method cost is high, fault rate is big, and the size that also can make whole product is bigger, simplifies not.

Utility model content

Utility model purpose: the problem and shortage existed for above-mentioned prior art, the purpose of this utility model is to provide a kind of high-efficiency LED radiator.

Technical scheme: the utility model discloses a kind of high-efficiency LED radiator, including the radiator body of hollow be fixed on the radiating fin of radiator body outer wall along radiator body short transverse, described radiator body inwall is distributed groined type gusset and includes horizontal gusset and vertical gusset, described radiating fin is equidistantly distributed on radiator body, and this radiating fin is provided with some louvres.

As further optimization of the present utility model, radiating fin described in the utility model is that the y-type structure of outward opening includes branch and bottom, 0.6-0.8 times of a length of bottom lengths of described branch.

As further optimization of the present utility model, louvre described in the utility model is U-shaped structure, and this louvre is arranged on the bottom of described radiating fin.

As further optimization of the present utility model, 2-2.5 times that branch spacing is radiating fin thickness of two adjacent radiating fins described in the utility model.

As further optimization of the present utility model, the position that radiating fin described in the utility model is fixed on radiator body outer wall is corresponding with the centre position of two vertical gussets on radiator body inwall.

nullBeneficial effect: the utility model is compared with prior art，Have the advantage that the utility model increases rib in radiator body，Can be while ensureing heat spreader structures intensity，Reduce the wall thickness of radiator body，And then improve the heat dispersion of radiator body，And the utility model uses groined type rib，Compare other structure ribs，Its structure stress is more uniformly distributed，For comparing the heat radiation wall of thickness of the same race，Its structural strength is more excellent，And the utility model abandoned existing circular louvre，Use U-shaped louvre，Increase radiating fin and extraneous contact area，Substantially increase radiating effect，Use U-shaped louvre to can guarantee that the structural strength at the radiating fin being provided with some louvres simultaneously，And radiating fin of the present utility model arranges all internal with the radiator body rib in position and matches，While ensureing structural strength，There is good radiating effect，There is good economic benefit.
