Description
Technical field
The invention belongs to heat sink technology field, be specifically related to a kind of radiator for LED.
Background technology
As everyone knows, so-called LED refers to light emitting diode, as one, current extensive use develops new type light source rapidly to LED light source, 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 brilliance, thereby can 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 restricting at present LED light source development are exactly heat conduction and the hot settlement issues of LED encapsulation, it is the heat dissipation problem of LED, LED is as light source, conventionally all need long continuous firing, even if for this cold light source of LED, work also can produce a large amount of thermal accumlations for a long time, this just requires the radiator operating efficiency of LED light source good, can remove to dredge heat energy by shorter pathway, reduce the infringement that excess Temperature brings to chip as far as possible, current way is that LED chip is encapsulated into heat sink falling on main support, then heat sink fall main support install be fixed on a large-scale radiating element, such as heat-radiating substrate, or aluminum base plate, heat sinkly fall being fixedly connected with normally between main support and radiating element and realize by two kinds of modes, the first is via heat-conducting cream transfer of heat, it two is that practical tin cream is by the mode of reflow soldering transfer of heat, and most importantly the technique of these two kinds of modes is all connected between radiator at LED chip and will produces high temperature, very easily hurt LED chip, cause luminous flux to decline, LED encapsulating structure damages, electrical parameter changes, light decay increases severely.
In general, in industry, traditional radiator normally designs according to concrete applicable cases, size is relatively fixing, and versatility is poor, and some producer is to adopt small-sized fans forced heat radiation for the radiating mode of LED at present, the method cost is high, fault rate is large, also can make the size of whole product larger, simplifies not.
Summary of the invention
Goal of the invention: the problem and shortage existing for above-mentioned prior art, the object of this invention is to provide a kind of high-efficiency LED radiator.
Technical scheme: the invention discloses a kind of high-efficiency LED radiator, comprise the radiator body of hollow and be fixed on the radiating fin of radiator body outer wall along radiator body short transverse, described radiator body inwall is distributed with groined type gusset and comprises 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 invention, the y-type structure that radiating fin of the present invention is outward opening comprises branching portion and bottom, and the 0.6-0.8 that described branching portion length is bottom lengths doubly.
As further optimization of the present invention, louvre of the present invention is U character form structure, and this louvre is arranged on the bottom of described radiating fin.
As further optimization of the present invention, the branching portion spacing of two adjacent radiating fins of the present invention is 2-2.5 times of radiating fin thickness.
As further optimization of the present invention, it is corresponding with the centre position of two vertical gussets on radiator body inwall that radiating fin of the present invention is fixed on position on radiator body outer wall.
Beneficial effect: the present invention compared with prior art, have the following advantages: the present invention increases rib in radiator body, can be in ensureing heat spreader structures intensity, reduce the wall thickness of radiator body, and then the heat dispersion of raising radiator body, and the present invention adopts groined type rib, compare other structure ribs, its structure stress is more even, compare the heat radiation wall of thickness of the same race, its structural strength is more excellent, and the present invention has abandoned existing circular louvre, adopt U-shaped louvre, increase radiating fin and extraneous contact area, greatly improve radiating effect, adopt U-shaped louvre can ensure be provided with the structural strength of radiating fin of some louvres simultaneously, and radiating fin setting position of the present invention all matches with the inner rib of radiator body, in ensureing structural strength, there is good radiating effect, there is good economic benefit.
