Abstract
The utility model discloses a high-power radiating pipe of an LED (Light Emitting Diode) lamp, which is characterized by comprising a U-shaped copper tube (1) with two closed ends, wherein two ends of the copper tube (1) are installed in a radiating piece (4), a fine copper powder layer (2) is fixed on the inner wall of the copper tube (1), a hollow cavity (3) is arranged at the center of the fine copper powder layer (2), liquid water is absorbed in the fine copper powder layer (2), and the hollow cavity (3) is in a vacuum state. The high-power radiating pipe of the LED lamp has a reasonable structure, and is simple and practical, low in cost, light in weight, high in heat transferring efficiency and good in radiating effect.
Description
Technical field
The utility model relates to a kind of heat pipe construction.
Background technology
Existing in the market its structure of heat pipe generally is a sintered copper bisque in copper pipe, and filling heat-conductive medium in copper pipe is delivered to the other end with heat from copper pipe one end through flowing of heat-conducting medium then.High-power LED lamp heat radiation at present all is that not only weight is big, and heat-conducting effect is poor with the aluminium section bar heat radiation.
Summary of the invention
The purpose of the utility model is exactly the deficiency to above-mentioned prior art, provides a kind of simple and practical, and cost is low, the high-powered LED lamp radiating tube that heat conduction efficiency is high.
The technical scheme that the utility model adopts is following:
A kind of high-powered LED lamp radiating tube; It is characterized in that it comprises the copper pipe that takes the shape of the letter U of sealed at both ends; Said copper pipe two ends are installed in the fin, are fixed with one deck capillary copper powder layer at the inwall of said copper pipe, are cavity at the center of capillary copper powder layer; In said capillary copper powder layer, be adsorbed with aqueous water, be vacuum state in the said cavity.
The U-shaped bottom of said copper pipe is a flat tube, and capillary copper powder layer porosity wherein is 45-55%.
The beneficial effect of the utility model has:
Rational in infrastructure, simple and practical, cost is low, and is in light weight, and heat conduction efficiency is high, good heat dissipation effect.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further:
As shown in Figure 1, in the utility model heat pipe it comprise the copper pipe that takes the shape of the letter U 1 of sealed at both ends, the two ends of copper pipe 1 are installed in the fin 4, and two heat pipes are installed in each fin 4.Inwall at said copper pipe 1 is fixed with one deck capillary copper powder layer 2, is cavity 3 at the center of capillary copper powder layer 2, is vacuum state in the cavity 3.The preferred flat tube that adopts of copper pipe 1 increases the contact area of pipe and chip, capillary copper powder layer 2 porosity be 45-55%.In said capillary copper powder layer 2, be adsorbed with aqueous water, the concrete amount of water is the maximal absorptive capacity of capillary copper powder layer 2.
When the bottom of the utility model copper pipe 1 is heated; Aqueous water vaporization becoming steam arrives copper pipe 1 from cavity 3 two ends in this place's capillary copper powder layer 2; Be condensed into aqueous water copper pipe 1 bottom again behind the fin 4 heat radiation backs, formed circulation, can be improved the radiating effect of fin 4 greatly.
Other undeclared part that the utility model relates to is identical with prior art.
