This 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 conduction of heat 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 work 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: in order to overcome the deficiencies in the prior art, it is provided that the LED radiator that a kind of work efficiency is good.

Technical scheme: for achieving the above object, this utility model provides a kind of LED radiator, radiator body including hollow, it is positioned at the radiating fin on described radiator body outer wall, described radiator body two ends are closed by top board and base plate, the base plate closed is provided with installing hole, described radiator body inwall is provided with helical form gusset, described radiating fin is perpendicular to described radiator body short transverse and is arranged on the outer wall of radiator body, and radiating fin is distributed on radiator body outer wall from radiator body top board to base plate, described radiating fin is provided with the opening Y type groove towards radiator body.

As further optimization of the present utility model, radiating fin described in the utility model is the downward structure of arc away from the termination, one end of described radiator body.

As further optimization of the present utility model, this utility model is positioned on the arbitrary sectional plane of radiator body and is equipped with some radiating fins, and the spacing between radiating fin and radiating fin is the 1/20-1/15 of radiator body cross section interior diameter.

As further optimization of the present utility model, this utility model is distributed in radiator body top board to the 1/20-1/15 that spacing is radiator body stage casing cross-sectional inner diameter of radiating fin intersegmental in radiator body.

As further optimization of the present utility model, this utility model is distributed in radiator body stage casing to the 1/18-1/10 that spacing is radiator body stage casing cross-sectional inner diameter of the radiating fin between radiator body base plate.

As further optimization of the present utility model, radiator body described in the utility model is frustum cone structure wide at the top and narrow at the bottom.

As further optimization of the present utility model, radiating fin described in the utility model is sector structure.

Beneficial effect: this utility model is compared with prior art, first heat passes in heat radiator body, then passed on radiating fin by heat radiator body, most heat produced by last LED is shed through free convection in atmosphere by radiating fin, this utility model uses helical form gusset, the relatively gusset of other planforms, in the case of ensureing radiator body wall thickness, ensure that the structural strength of radiator body, helical form rib coordinates radiating fin of the present utility model distribution simultaneously, its better heat-radiation effect, the heat in heat radiator body can be made quickly to be delivered to radiating fin, and this utility model uses the radiating fin of different spacing distribution, while ensureing radiating effect, save material, and then reduction production cost, improve product competitiveness in the market, there is good economic benefit.
