Description

A kind of heat-pipe radiator that is used for high-powered LED lamp

Technical field

The utility model belongs to heat dissipation equipment, is meant a kind of heat-pipe radiator that is used for high-powered LED lamp especially.

Background technology

Enforcement along with the national environmental protection energy saving policy; The LED large-scale application has become trend; Yet " heat radiation " and " light decay " the two big technical barriers that influence the LED large-scale application still do not solve as yet fully, become the road blocking tiger of restriction industry development, and the heat pipe heat radiation technology relies on its good performance of heat dissipation to be expected to solve puzzlement industry " heat radiation " and " light decay " problem for many years; Thereby can further improve the life-span of LED lamp; The product price ratio is tending towards rationally, really makes the LED lamp can come into huge numbers of families, rather than rely on public subsidies and mandatory implementation merely.

Summary of the invention

The purpose of the utility model provides a kind of high-efficiency heat pipe system that is used for the high-powered LED lamp heat radiation, relies on its good performance of heat dissipation to replace present LED lamp with the heat radiation aluminium section bar, through increasing substantially LED lamp radiating efficiency, solves heat radiation and the light decay problem of LED.

The overall technology design of the utility model is:

A kind of heat-pipe radiator that is used for high-powered LED lamp comprises led light source, the box-like evaporation cavity of hollow and is connected the pipeline on the evaporation cavity, and evaporation cavity and pipeline form the closed loop; Evaporation cavity is that hollow is box-like; And be provided with evaporation mouth, refluxing opening and filling exit, and vacuumize from filling exit, inject chemical working medium; And filling exit sealed; Form hot-pipe system, closely be connected with led light source through the box-like evaporation cavity of hollow, fully the heat of led light source through being that the hot-pipe system of core is efficiently dispersed with the box-like evaporation cavity of hollow.

What need further specify is must be the large-area structure of being close to of trying one's best between the evaporation cavity of led light source and heat pipe.

The concrete technical measures of the utility model also have:

For obtaining radiating efficiency preferably; The preferred construction design is: it is box-like that the evaporation cavity of heat-pipe radiator is designed to hollow; The face that is fitted and connected of evaporation cavity and LED lamp source is smooth smooth, and requirement on machining accuracy is very high, so just can make and form best heat transfer mode between heat pipe and the led light source.

More unobstructed for the working medium circulation that makes the heat-pipe radiator pipeline, the preferred construction design is: the evaporator section that is connected the pipeline on the evaporation cavity adopts the linear pattern design, and the evaporation mouth is located at the evaporation cavity top.

For increasing area of dissipation, the preferred construction design is: the reflux section that is connected the pipeline on the evaporation cavity adopts the coiled helical design, is connected and is welded with the heat dissipation metal silk on the pipeline on the evaporation cavity, to play further expansion area of dissipation and overall fixed effect.

For further obtaining heat-pipe working medium gravity circulating effect preferably, the preferred construction design is: the position of evaporation mouth is higher than the position of refluxing opening, and the two all forms with evaporation cavity and is tightly connected.

Be the sealing of assurance heat pipe and good filling process, the preferred construction design is: filling exit is located on the evaporation cavity.

The technological progress that the utility model is obtained is:

1, heat-pipe radiator is owing to adopt the box-like evaporation cavity design of hollow; Make the applying that realizes maximum area between led light source and the heat pipe evaporation cavity; And then form best heat transmission design, and producing good heat exchange effect, its heat transmission speed is more than tens times of original aluminium section bar radiator.

2, the pipeline of linear pattern evaporator section and spiral reflux section formation launches the back area of dissipation and be far longer than the primary aluminum Section Bar Heat Sinks, and the isothermal of heat-pipe radiator is fine, and the top and the bottom temperature difference are no more than 1 ^oC, so its heat dispersion will be far above the primary aluminum Section Bar Heat Sinks.

3, the pipeline of linear pattern evaporator section and spiral reflux section formation; Its used metal material weight only is equivalent to 1/5 of primary aluminum Section Bar Heat Sinks, not only saves cost, and greatly reduces the weight of LED lamp; The installation difficulty that this has just reduced light fixture has improved the safety coefficient of light fixture.
