Abstract

The utility model discloses a high-power LED (light-emitting diode) lamp radiator, and relates to radiators relevant to high-power LED lamps, aiming at solving the problems that as for the existing high-power LED lamp radiator, aluminum alloy sections are commonly used, the radiating area is small, the radiating effect is poor and the weight is heavier, and the production efficiency is lower as fins are connected with aluminum cores by welding in the production process of the existing high-power LED lamp radiator. The aluminum cores are arranged in the radiating fins; aluminum blocks are fixed on the top ends of the aluminum cores; a first positioning cover is fixed between each aluminum block and each radiating fin; a second positioning cover is fixed between the bottom end of each aluminum core and each radiating fin; the outer walls of the aluminum cores are provided with axial copper pipe grooves; the straight sections of copper pipes are arranged in the copper pipe grooves of the aluminum cores; and the bent sections of the cooper pipes are arranged in through holes on the aluminum blocks. In the utility model, the radiating fins which are formed by stamping, fastening and splicing of aluminum sheets are increased, so the radiating area is greatly enlarged; and the copper pipes are additionally arranged between the aluminum cores and the radiating fins, thus achieving good radiating effect.

Description

High-power LED (Light-Emitting Diode) lamp radiator

Technical field

The utility model relates to the radiator relevant with high-powered LED lamp.

Background technology

Existing high-power LED (Light-Emitting Diode) lamp radiator generally uses aluminium alloy extrusions, and its area of dissipation is little, and radiating effect is poor, and weight is heavier.Because existing high-power LED (Light-Emitting Diode) lamp radiator its fin in process of production all uses welding with being connected of aluminium core, production efficiency is lower.

The utility model content

The purpose of this utility model is generally to use aluminium alloy extrusions in order to solve existing high-power LED (Light-Emitting Diode) lamp radiator, and its area of dissipation is little, and radiating effect is poor, and weight is heavier.And existing high-power LED (Light-Emitting Diode) lamp radiator in process of production its fin all use welding with being connected of aluminium core, the problem that production efficiency is lower, and then high-power LED (Light-Emitting Diode) lamp radiator is provided.

The utility model is to address the above problem the technical scheme that proposes to be: comprise the first location lid, aluminium block, copper pipe, the aluminium core, radiating fin, the second location lid, screw and lampshade, lampshade is arranged on above the top of radiating fin, the aluminium core is arranged in the aluminium core via hole of radiating fin, aluminium block is fixed on above the top of aluminium core, be connected by screw between aluminium block and the aluminium core, be fixed with the first location lid between aluminium block and the radiating fin, be fixed with the second location lid between the bottom of aluminium core and the radiating fin, be provided with through hole above the aluminium block, be provided with axial copper pipe groove above the outer wall of aluminium core, the straight length of copper pipe is arranged in the copper pipe groove of aluminium core, and the bending section of copper pipe is arranged in the through hole above the aluminium block.

The beneficial effects of the utility model: one, with respect to existing Section Bar Heat Sinks, piece together the radiating fin quantity form by aluminium flake punching press button and increase, thereby area of dissipation increases greatly, and finished weight alleviates, thereby reduced raw-material use.Two, between aluminium core and radiating fin, add copper pipe, make the direct contact heating body of copper pipe, thereby improved the heat conductivility of radiator, copper pipe and aluminium core fit tightly, the heat of deriving is transferred to the aluminium core, and the radiating fin of being close to by the aluminium core scatters again, has reached better heat radiating effect.Three, radiating fin and aluminium core fasten with the location lid of close-fitting, have replaced existing welding manner, have optimized production technology, have improved production efficiency.
