Abstract
The utility model discloses an LED (Light Emitting Diode) projection lamp radiator, comprising a base plate and a plurality of radiating fins distributed on the base plate, wherein the base plate and the radiating fins are molded in an integrated aluminum extrusion way; a sealing cavity is arranged in the base plate; a phase change heat transfer working medium is arranged in the cavity; a plurality of integrated-molded tiny bulges are arranged on the bottom of the cavity. According to the LED projection lamp radiator, a main body adopts an aluminum alloy extrusion section and comprises an integrated extrusion cavity structure, a phase change technology is adopted for heat transfer, the product weight is lightened, the radiating capability is improved, the service life of a whole lamp is prolonged, and the advantages that the homeothermy is good, the thermal resistance is small, the raw materials are saved, and the like are achieved.
Description
Technical field
The utility model relates to LED lamp heat sink technology field, especially relates to a kind of LED projecting lamp radiator.
Background technology
Current LED projecting lamp radiator generally adopts Al squeezing material or pack alloy to be made.Due to Al squeezing material or pack alloy heat transfer coefficient low, cause that radiator heat conduction is slow and each several part is inhomogeneous, little with the environment temperature temperature difference apart from the fin part that thermal source is far away, can not give full play to the effective area of heat radiator fin.In order to reach better radiating effect, can only strengthen area of dissipation, improve fin height; Therefore caused heat radiation uniformity bad, equivalent thermal resistance is large, and serious waste metal material, and volume is larger, and processing technology is bad.
Summary of the invention
The deficiency existing for above-mentioned prior art, the purpose of this utility model is to provide the phase transformation LED projecting lamp radiator of integrated molding, main body adopts aluminum alloy extrusion section bar, the cavity body structure that comprises integrated extruding, adopt phase change technique to conduct heat, alleviate product weight, improved heat-sinking capability, extended the whole lamp life-span.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of LED projecting lamp radiator, comprise base plate and be laid in the some radiating fins on base plate, the integrated aluminium extrusion moulding of base plate and radiating fin, in described base plate, be provided with sealed cavity, in described cavity, be provided with can phase-change heat transfer working medium, the bottom of described cavity is provided with some minute protrusions of integrated molding.
Wherein, the LED projecting lamp that is provided with integrated molding in described cavity is installed reinforcement, and described LED projecting lamp is installed reinforcement described cavity is separated into some independently cavitys.
Wherein, described LED projecting lamp is installed reinforcement and is provided with LED projecting lamp installing hole.
Wherein, the not isometric radiating fin of the integrated moulding of described radiating fin.
Adopt after technique scheme, the advantage that compared to the prior art the utility model had is:
The phase transformation LED projecting lamp radiator of the integrated molding of the utility model design, it is simple and reasonable, compare traditional heat-dissipating device, the base plate of thermal source (LED) by there being some minute protrusions conducts heat to working medium that can phase-change heat transfer, working medium is subject to thermal evaporation to form gas, take away heat, gas is met condensation knot release heat at far-end, by fin, heat is dispersed in environment uniformly simultaneously; Due to the rapid property of gas diffusion, uniformity, has guaranteed the rapidity that heat conducts, uniformity, the temperature between base plate of radiator each point will have splendid uniformity, thereby makes the temperature of fin approach consistent, improved the area utilization of fin, thermal resistance reduction will make far-end fin temperature be promoted, and save area of dissipation, reduce weight, reduced the volume of radiator, or can obtain better radiating effect under equal volume, in the service life that obtains more growing, improve reliability.
To sum up, LED projecting lamp radiator described in the utility model its be embodied in a little:
1, uniform temperature is good.Due to the inner perfusion of cavity structure phase-change working substance, the working medium boiling of being heated, steam is filled into rapidly cold junction, and this heat transfer rate is fast more than solid metal heat conduction, and equivalence performance is exactly that thermal resistance is low, and a radiator temperature of putting reaches unanimity.
2, thermal resistance is little.Because uniform temperature is guaranteed, make all fins, all positions can reach approximate consistent temperature, and so whole equivalent thermal resistance reduces greatly.
3, save material.Uniform temperature is good, makes all fins all can well be operated in state point, compares traditional heat-dissipating device and can greatly reduce fin area, reduces materials'use amount.

The specific embodiment
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
Embodiment, is shown in shown in Fig. 1 to Fig. 3.
A LED projecting lamp radiator, comprises base plate 1 and radiating fin 2, the integrated aluminium extrusion moulding of base plate 1 and radiating fin 2.The not isometric radiating fin 2 of radiating fin 2 integrated moulding.
In cavity 3, be provided with can phase-change heat transfer working medium, cavity 3 bottoms are provided with some minute protrusions 4, these some minute protrusions 4 can be also the fine structures such as some microflutes, its role is to increase the heat exchange area of working medium and cavity bottom.
Thermal source LED projecting lamp is by there being the base plate 1 of minute protrusions 4 that heat is conducted to working medium, and working medium is subject to thermal evaporation to form gas, takes away heat simultaneously, and gas is met condensation knot release heat at far-end, by radiating fin 2, heat is dispersed in environment uniformly.
LED projecting lamp is installed reinforcement 5 and is provided with LED projecting lamp installing hole, is convenient to mounted LED lamp body, the bore position that the effect of LED projecting lamp installation reinforcement 5 is to strengthen the structural strength of this LED projecting lamp radiator and described LED projecting lamp installing hole is provided.
