Description
Technical field
The utility model relates to heat sink technology field, specifically provides a kind of LED radiator.
Background technology
The same with conventional light source, semiconductor light emitting diode (LED) also can produce heat during operation, and how much it depends on overall luminous efficiency.Under powering up energy outside, the radiation recombination generation electroluminescent in electronics and hole, the light radiated near PN junction also needs just can arrive at external world's (air) through the semiconductor medium of chip (chip) itself and encapsulation medium.Combination current injection efficiency, radioluminescence quantum efficiency, chip exterior light extraction efficiency etc., finally probably only have the input electric energy conversion of 30-40% to be luminous energy, and the energy of all the other 60-70% mainly transforms heat energy with the form of the lattice vibration of non-radiative recombination generation.The method of LED heat radiation mainly contains: aluminium radiating fin, fan, heat pipe etc., these heat dissipation technologys are relatively ripe.In recent years, the technology that thermodynamics combines with air fluid mechanics solves heat dissipation problem, although dispel the heat, more effective radiator is existing at present exists, but heat dispersion is required that very high radiator still awaits breaking through, the technology how utilizing thermodynamics to combine with air fluid mechanics realizes heat conduction, heat-radiating integrated, makes the even more ideal technological difficulties being people always and thirsting for solving of radiator heat-dissipation effect.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is the LED radiator providing a kind of better heat-radiation effect.
For achieving the above object, this aspect adopts following technical scheme:
A kind of LED radiator, comprise body, radiating fin, top cover, bottom and wind-force radiating subassembly, described body has internal cavities, body outer surface is laid with some described radiating fins, described radiating fin there is cavity and with the cavity connects of body, the cavity inner surface of radiating fin and body has the capillary structure of aluminium powder and copper powder mixed sintering, and on body, the two ends of corresponding described cavity are covered with top cover and bottom respectively, and described wind-force radiating subassembly is arranged on top cover.
Further, described wind-force radiating subassembly comprises arc heat radiation group, curved surface arc flabellum group and holder, described arc heat radiation group, curved surface arc flabellum group are an overall structure, described arc heat radiation group is arranged on curved surface arc flabellum group, curved surface arc flabellum group is movably arranged on holder, can rotate around holder, described holder is fixedly installed on top cover, for fixing curved surface arc flabellum group.
Further, described arc heat radiation group is made up of some arc flabellums, and described arc flabellum outward flange is the arc of indent, and described curved surface arc flabellum group is made up of some curved surface arc flabellums, and described curved surface arc flabellum outward flange is curved surface arc outwardly.
Further, through hole is offered in the middle part of described top cover.
A kind of LED radiator of the present utility model, making exchange capability of heat greatly improve by arranging wind-force radiating subassembly, good heat dissipation effect, can meet present stage great power LED cooling demand.
Accompanying drawing explanation
Fig. 1 is LED radiator of the present utility model direction structure schematic diagram;
Fig. 2 is the A-A sectional view shown in Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and the embodiments, the utility model is described in further detail:
Refer to Fig. 1, a kind of LED radiator of the present utility model, comprise body 1, radiating fin 2, top cover 3, bottom 4 and wind-force radiating subassembly 5.
Described body 1 has internal cavities, and body 1 outer surface cloth is provided with some described radiating fins 2, and on body 1, the two ends of corresponding described cavity are covered with top cover 3 and bottom 4 respectively.
Incorporated by reference to consulting Fig. 2, described radiating fin 2 there is cavity and with the cavity connects of body 1, and described radiating fin 2 has the capillary structure of aluminium powder and copper powder mixed sintering with the cavity inner surface of body 1.Through hole (not shown) is offered in the middle part of described top cover 3.
Described wind-force radiating subassembly 5 comprises arc heat radiation group 52, curved surface arc flabellum group 51 and holder (not shown).Described arc heat radiation group 52, curved surface arc flabellum group 51 are an overall structure, and described arc heat radiation group 52 is arranged on curved surface arc flabellum group 51, and curved surface arc flabellum group 51 is movably arranged on holder, can rotate around holder.Described holder is fixedly installed on top cover 3, for fixing curved surface arc flabellum group 51.
Described arc heat radiation group 52 is made up of some arc flabellums, and described arc flabellum outward flange is the arc of indent.Described curved surface arc flabellum group 51 is made up of some curved surface arc flabellums, and described curved surface arc flabellum outward flange is curved surface arc outwardly.
Operation principle of the present utility model is: by arranging wind-force radiating subassembly 5, utilize convective principles, draught head principle and wind-force principle to promote described curved surface arc flabellum group to rotate, drive air circulation and then dispel the heat, that is: hot-air gentlier can rise, and cold air is heavier can decline, because bottom 4 temperature that is heated is higher, atmospheric density is less, thus can rise along body 1 inner chamber, flows out from described curved surface arc flabellum group, drive described curved surface arc flabellum group to rotate, so dispel the heat.
A kind of LED radiator of the present utility model, making exchange capability of heat greatly improve by arranging wind-force radiating subassembly 5, can meet present stage great power LED cooling demand, and cost significantly reduces simultaneously.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure transformation utilizing the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
