Description

A kind of great power LED cooling piece

Technical field

The utility model discloses a kind of heat radiating fin structure, particularly a kind of great power LED cooling piece.

Background technology

Light emitting diode (Light Emittin Diode, LED) as solid state light emitter of new generation, with long lifespan,

The many merits such as energy-efficient, environmental protection, are widely applied to display!With science and technology hair in lighting field Exhibition, advanced technology is constantly applied in semiconductor production, so that LED luminous efficiency is constantly lifted, cost continuous decrease. LED core is PN junction, and electric energy is converted directly into luminous energy by the electronics and hole for noting people in PN junction compound tense, but not It is that the luminous energy of all conversions is all enough transmitted into outside LED, it can exist

It is to produce huge side effect to light fixture to convert this heat energy of heat energy by absorbing sheet inside PN junction and epoxy resin silica gel, If can not effectively radiate, it can raise LED internal temperatures, temperature is higher, and LED luminous efficiency is lower, and LED life-span gets over It is short, under serious conditions, LED wafer can be caused to fail at once, so radiating is still the huge obstacle of great power LED application.

The content of the invention

For problem above, the utility model discloses a kind of great power LED cooling piece, solve to a certain extent big The heat dissipation problem of power outdoor LED lamp, solves one of important bottleneck of puzzlement LED development.

The utility model discloses a kind of great power LED cooling piece, a kind of described great power LED cooling piece includes side Wall, long fin, short fin, fixing hole and ventilation slot, it is characterised in that：Described side wall is located at both sides, described length Fin is apart from one another by arrangement, in the middle of the wall of both sides side, and described length fin length is inconsistent, has on described side wall Fixing hole and two ventilation slots, described long fin have a ventilation slot.

A kind of great power LED cooling piece disclosed in the utility model, a kind of fin of described great power LED cooling piece Length is inconsistent, is divided into long and short two length, the most long length of short fin is 2/3rds of long fin length, most it is short not Less than 1/2nd of long fin length, the fin highly differed is conducive to sky in the case of the relative reduction of area of dissipation Air-flow leads to, and accelerates cooling rate.

A kind of a kind of great power LED cooling piece disclosed in the utility model, described the long of great power LED cooling piece is radiated Piece and short fin are assembled, it is ensured that the length of adjacent two pieces of fin is not apart from one another by arrangement using one is long and the other is short Unanimously, although area is reduced but adds rate of air circulation, and integral heat sink can be made more efficient.

On a kind of great power LED cooling piece disclosed in the utility model, a kind of side wall of described great power LED cooling piece Have four mounting holes, two one group, respectively positioned at fin upper and lower ends, be fixedly connected uses for structure and structure, when need Two or more LED light group is wanted to be connected in use, as bolt fixing hole, convenient use demand adds and uses flexibility.

On a kind of great power LED cooling piece disclosed in the utility model, a kind of side wall of described great power LED cooling piece Two ventilation slot lengths be not less than side wall length 2/3rds, width is not more than 1st/15th of side wall overall width, should Ventilation slot in the range of the surplus not integrally-built intensity of impression side wall, while improving rate of air circulation, is drastically increased The integrally-built radiating effect of fin.

A kind of a kind of great power LED cooling piece disclosed in the utility model, described the long of great power LED cooling piece is radiated Ventilation slot on piece is one, and length is not less than long fin length 2/3rds, and width is not more than long fin overall width 1/10th, in the case where not influenceing overall construction intensity and area of dissipation, as long fin, its ventilation slot can make whole Body wind speed flow increases, it is to avoid higher than short fin long fin by gas barrier, reduce air mass flow.

A kind of great power LED cooling piece disclosed in the utility model, a kind of overall material of described great power LED cooling piece Matter uses aluminum alloy material, is processed using stretching aluminium mode, ventilation slot and connection are equipped with side wall and long fin Structure bulk strength is unaffected in the case of hole, while using the material favorable rust preventing effect, without doing water-proofing treatment again, simultaneously Radiating effect is good.

Embodiment

With reference to the accompanying drawings and detailed description, the utility model is further elucidated, it should be understood that following specific embodiment parties Formula is merely to illustrate the utility model rather than limits scope of the present utility model, after the utility model has been read, this Modification of the art personnel to the various equivalent form of values of utility model falls within the model that the application appended claims are limited Enclose.

As shown in Figure 1,2 and 3, the utility model discloses a kind of great power LED cooling piece, described is a kind of high-power LED fin include side wall 1, long fin 3, short fin 2, fixing hole 4 and ventilation slot 5 and 1.Described side wall 1 is located at The structure left and right sides, described short fin 2 is located between long fin 3 and side wall 1, and described fixing hole 4 is located at both sides side On wall 1, respectively positioned at the upper and lower ends of side wall 1, two described ventilation slots 5 are located on side wall 1, and described ventilation slot 7 is located at length On fin 3.

As one kind preferably, a kind of fin of described great power LED cooling piece uses welding procedure, low using height Difference, the radiator structure of centre ventilation, considerably increases the radiating effect of LED.

As one kind preferably, a kind of described fin of described great power LED cooling piece is divided into two length, is formed Waveform, the height of long fin does not influence overall structure inner air flow.

Weldering is spaced as the long fin and short fin of a kind of a kind of preferred, described great power LED cooling piece It is connected on pier, forms one high and one low arrangement straggly.

As one kind preferably, a kind of side wall upper and lower ends of described great power LED cooling piece respectively have two fixing holes, when Need multiple structures to connect in use, fixing hole can be passed through with bolt, will be connected between structure.

As it is a kind of preferably, the two ventilation slot length-width ratios and area of a kind of described great power LED cooling piece are neither Structure bulk strength can be influenceed, good result of ventilating heat dissipation can be played again.

It is used as the ventilation slot length-width ratio on a kind of long fin of a kind of preferred, described great power LED cooling piece and face Product had not both interfered with structure bulk strength equally, and good result of ventilating heat dissipation can be played again.
