Abstract

The invention discloses a high-power LED lamp radiating tube. The high-power LED lamp radiating tube is characterized by comprising a U-shaped copper tube (1) with two ends sealed, the two ends of the copper tube (1) are mounted in radiating fins (4), a hollow cavity (3) is arranged at the center of a capillary copper powder layer (2) which is fixed on the inner wall of the copper tube (1), liquid water is absorbed in the capillary copper powder layer (2), and the hollow cavity (3) is internally in the vacuum state. The high-power LED lamp radiating tube is reasonable in structure, simple, practical, low in cost, lightweight, high in heat conduction efficiency and good in radiating effect.

Description

The high-powered LED lamp radiating tube
Technical field
The present invention relates to a kind of heat pipe construction.
Background technology
Its structure of existing heat pipe generally is sintered copper bisque in copper pipe in the market, and then filling heat-conductive medium in copper pipe is delivered to the other end with heat from copper pipe one end by flowing of heat-conducting medium.At present high-power LED lamp heat radiation all is that not only weight is large, and heat-conducting effect is poor with the aluminium section bar heat radiation.
Summary of the invention
Purpose of the present invention is exactly for above-mentioned the deficiencies in the 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 solution used in the present invention is as follows:
A kind of high-powered LED lamp radiating tube, it is characterized in that it comprises the sealed at both ends copper pipe that takes the shape of the letter U, described copper pipe two ends are installed in the fin, inwall at described copper pipe is fixed with one deck capillary copper powder layer, be cavity at the center of capillary copper powder layer, absorption has aqueous water in described capillary copper powder layer, is vacuum state in the described cavity.
The U-shaped bottom of described copper pipe is flat tube, and capillary copper powder layer porosity wherein is 45-55%.
Beneficial effect of the present invention has:
Rational in infrastructure, simple and practical, cost is low, and is lightweight, and heat conduction efficiency is high, good heat dissipation effect.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described:
As shown in Figure 1, among the present invention heat pipe it comprise the sealed at both ends copper pipe that takes the shape of the letter U 1, 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 described 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 described capillary copper powder layer 2 interior absorption aqueous water is arranged, the concrete amount of water is the maximal absorptive capacity of capillary copper powder layer 2.
When the bottom of copper pipe 1 of the present invention is heated, aqueous water vaporization in this place's capillary copper powder layer 2 becomes steam arrives copper pipe 1 from cavity 3 two ends, after after fin 4 heat radiations, be condensed into again copper pipe 1 bottom of aqueous water, form circulation, can greatly improve the radiating effect of fin 4.
The undeclared part of other that the present invention relates to is same as the prior art.
