Description
[technical field]
The present invention relates to radiator, relate in particular to a kind of radiator of great power LED.
[background technology]
As everyone knows, so-called LED is meant light emitting diode, led light source develops new type light source rapidly as a kind of present extensive use, energy-conservation, efficient, advantages such as volume is little, the life-span is long, response speed is fast, driving voltage is low, shock resistance brilliance have been compared with conventional light source, enlarge industry size, market share thereby can develop rapidly, the industry tendency leads under, its technology is also being brought in constant renewal in and in-depth, but the maximum technology barriers that restricting the led light source development at present are exactly heat conduction and the heat sink problem of falling, the i.e. heat dissipation problem of LED of LED encapsulation.LED is as light source, usually 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 radiating element operating efficiency of led light source good, can remove to dredge heat energy by short pathway, reduce the too high infringement that brings to chip of temperature as far as possible, present way is that led chip is encapsulated into heat sink falling on the main support, then the heat sink main support that falls is installed and fixed on the large-scale radiating element, such as heat-radiating substrate, perhaps aluminum base plate, heat sinkly fall fixedly connected between main support and the radiating element and normally realize by dual mode, the first is via the heat-conducting cream transfer of heat, and it two is to use the mode of tin cream by the reflow soldering transfer of heat.And most importantly the technology of this dual mode all is connected at led chip and will contacts high temperature between the radiator, very easily hurts the chip of LED, causes luminous flux to descend, and the LED encapsulating structure damages, and electrical parameter changes, and light decay increases severely.
In general in industry, traditional radiator normally designs according to concrete applicable cases, the size relative fixed, versatility is relatively poor, the radiating mode that present some producer is used for LED is to adopt the small-sized fans forced heat radiation, the cost height of the method, and fault rate is big, can make that also the size of entire product is bigger, simplifies inadequately.
[summary of the invention]
The present invention provides a kind of good heat dissipation effect, cost is low, structure is simplified LED radiator for addressing the above problem.
The technical scheme that the present invention addresses the above problem is: radiator involved in the present invention, it is characterized in that the LED radiator is divided into two parts up and down, and top is the heat dissipation wind channel plate, and the bottom is a cooling base, and two parts link together; Described heat dissipation wind channel plate is provided with several spiral heat dissipation through holes, and described spiral heat dissipation through hole bore is the form of amplifying gradually from top to bottom; Described cooling base is provided with some air intake passages, arranges the taper projection in described air intake passage, and described taper projection is corresponding nested with described spiral heat dissipation through hole.
Described heat-radiating substrate closely links to each other with heater element;
Described air intake passage has the mouth of crossing in the centre, is provided with the taper projection at the described mouthful place that crosses.
The invention has the beneficial effects as follows: utilize bionics principle, imitation ant nest structure, can regulate the convection current degree automatically according to calorific intensity, the heat radiation through hole is long more, bore differs many more up and down, the strong more speed of its heat-sinking capability of finding time is also fast, and the shape of making spiral can realize simplifying of size under the situation that does not influence heat-sinking capability; In the centre of cooling base, UNICOM's air intake passage forms the mouth that crosses of air intake passage, and solution that can be better is in the middle part of radiator, the problem that radiating effect is poor more.

Fig. 1 is one embodiment of the invention structural representation;
Fig. 2 is a cutaway view of the present invention.
Among the figure: 1, heat dissipation wind channel plate; 2, cooling base; 3, spiral heat dissipation passway; 4, taper projection; 5, air intake passage; 6, heater element.
[specific embodiment]
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.
With reference to the accompanying drawings, as seen radiator involved in the present invention in the present embodiment integral body present rectangle, top is heat dissipation wind channel plate 1, the bottom is a cooling base 2, two parts link together, the heat dissipation wind channel plate 1 on top and the cooling base 2 of bottom can be fasten also can be the engaging or nest together, both are joined together in a word.
Described heat dissipation wind channel plate 1 is provided with several spiral heat dissipation through holes 3, visible in the drawings regularly arranged spiral heat dissipation through hole 3, and described spiral heat dissipation through hole 3 bores are the form of amplifying gradually from top to bottom, and it is little promptly to go up bore, and the bottom bore is big.
Described cooling base 2 is provided with some air intake passages 5, arranges taper projection 4 in described air intake passage 5, and described taper projection 4 is corresponding nested with described spiral heat dissipation through hole 3.
Described cooling base 2 closely links to each other with heater element 6; each taper projection 4 bottoms all corresponding heater element 6; by supporting taper projection 4 and spiral heat dissipation through hole 3; the bionical structure of ant nest; this structure of Btu utilization that heater element 6 produces promptly can be discharged; realize heat sinking function, reduce the heat production on the led light source, the protection led light source.
Generally speaking, mid portion is difficult to heat radiation on radiator, in order to address this problem better, is to allow air intake passage 5 cross in the centre at described air intake passage, is provided with the mouth that crosses, and also is furnished with taper projection 4 at the described mouthful place that crosses.
In order to reduce radiator integral weight, make it lighter, in actual production process, can adopt lighter material such as heat-resistant engineering plastic to make heat dissipation wind channel plate 1.
The present invention's but effect simple in structure is good, utilize bionics principle, imitation ant nest structure, can automatically regulate the convection current degree according to calorific intensity, the heat radiation through hole is more long, and bore differs more many up and down, and the more strong speed of its heat-sinking capability of finding time is also fast, the shape of making spiral can in the situation that does not affect heat-sinking capability, realize simplifying of size; In the centre of cooling base, UNICOM's air intake passage, the mouth that crosses of formation air intake passage, solution that can be better is in the more poor problem of middle radiating effect. Adopt engineering material cheap economic and practical, and the quality of product has also obtained further control, like this product not only size simplify, and light small and exquisite, radiating effect but surmounts existing product greatly, and broken away from fully with ventilating fan this passive heat radiation concept of dispelling the heat, need not provide in addition the energy to go to finish the heat radiation process.
