Abstract
The invention provides an LED heat sink which comprises a hollow heat sink body and heat dissipation fins located on the outer wall of the heat sink body. The two ends of the heat sink body are sealed by a top plate and a bottom plate. A mounting hole is formed in the bottom plate for sealing. The inner wall of the heat sink body is provided with a spiral rib plate. The heat dissipation fins are arranged on the outer wall of the heat sink body and are perpendicular to the height direction of the heat sink body. The heat dissipation fins are distributed on the outer wall of the heat sink body at intervals from the top plate to the bottom plate of the heat sink body. Y-shaped grooves with openings facing the heat sink body are formed in the heat dissipation fins.

Background technology
As everyone knows, so-called LED refers to light emitting diode, LED light source develops new type light source rapidly as the current extensive use of one, 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, thus expansion industry size can be developed rapidly, market share, industry tendency leads under, its technology is also in continuous renewal and in-depth, but the maximum technology barriers that govern LED light source development are at present exactly the heat transfer of LED and hot settlement issues, the i.e. heat dissipation problem of LED, LED is as light source, usually long continuous firing is all needed, even if for this cold light source of LED, long work also can produce a large amount of thermal accumlations, this just requires that the radiator operating efficiency of LED light source is good, can be gone by shorter pathway to dredge heat energy, reduce the too high infringement brought to chip of temperature as far as possible, current way LED chip is encapsulated into heat sinkly to fall on main support, then the heat sink main support that falls is installed and is fixed on a large-scale radiating element, such as heat-radiating substrate, or aluminum base plate, heat sinkly fall being fixedly connected with between main support and radiating element and normally realized by two kinds of modes, the first is via heat-conducting cream transfer of heat, it two is practical tin cream modes by reflow soldering transfer of heat, and most importantly the technique of these two kinds of modes is all connected between radiator in LED chip and will produces high temperature, very 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 normally designs according to embody rule situation, size is relatively fixing, and versatility is poor, and some producer is used for the radiating mode of LED is at present adopt small-sized fans forced heat radiation, the method cost is high, fault rate is large, the size of whole product also can be made larger, simplify not.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, provides the LED radiator that a kind of operating efficiency is good.
Technical scheme: for achieving the above object, the invention provides a kind of LED radiator, comprise the radiator body of hollow, be 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 arranged on the outer wall of radiator body perpendicular to described radiator body short transverse, and radiating fin is distributed in from radiator body top board to base plate radiator body outer wall, described radiating fin is provided with the Y type groove of opening towards radiator body.
As further optimization of the present invention, radiating fin of the present invention is the downward structure of arc away from the termination, one end of described radiator body.
As further optimization of the present invention, the present invention 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 invention, the spacing that the present invention is distributed in radiating fin intersegmental in radiator body top board to radiator body is the 1/20-1/15 of radiator body stage casing cross-sectional inner diameter.
As further optimization of the present invention, the spacing of the radiating fin that the present invention is distributed between radiator body stage casing to radiator body base plate is the 1/18-1/10 of radiator body stage casing cross-sectional inner diameter.
As further optimization of the present invention, radiator body of the present invention is frustum cone structure wide at the top and narrow at the bottom.
As further optimization of the present invention, radiating fin of the present invention is sector structure.
Beneficial effect: the present invention compared with prior art, first heat passes in heat radiator body, then pass on radiating fin by heat radiator body, the most heat that last LED produces is shed through free convection in atmosphere by radiating fin, the present invention adopts helical form gusset, compared with the gusset of other planforms, when ensureing radiator body wall thickness, the structural strength of radiator body can be ensured, helical form rib coordinates radiating fin of the present invention to distribute simultaneously, its better heat-radiation effect, the heat in heat radiator body can be made to be delivered to radiating fin fast, and the radiating fin that the present invention adopts different spacing to distribute, while ensureing radiating effect, save material, and then reduction production cost, improve product competitiveness in the market, there is good economic benefit.
