Description
Technical field
The present invention relates to electronic applications, specifically a kind of foam metal LED radiator device.
Background technology
LED refers to light emitting diode, is a kind of semiconductor electronic component that can convert electrical energy into luminous energy.LED has
The advantages that small volume, long lifespan, power consumption are low, reaction speed is fast, luminous efficiency is high, energy-conserving and environment-protective, it is replacement generally acknowledged in the industry
Conventional light source turns into the product of the most competitiveness of light source of new generation.At present, LED as photoelectric device in life it is big
Amount application, but the electric energy in its course of work only less than 20% is converted into luminous energy, remaining electric energy is distributed with form of heat.
Because it is mainly generated heat by chip, and chip area is smaller, and with the increase of input power, the heat accumulated on chip will more
Come more, temperature also more and more higher, especially high-power LED lamp, when its operating temperature exceedes the carrying temperature of chip,
LED luminous efficiency will be reduced quickly, produce obvious light decay, while device emission wavelength becomes big, and red shift occurs, finally leads
Cause to use the lost of life.According to A Leiniusi rules, temperature often reduces by 10 DEG C, and LED life-span can extend 2 times.Heat dissipation problem
Solves the illumination that LED will be made to be increasingly being applied under public illumination and harsh and unforgiving environments.
The content of the invention
It is an object of the present invention to provide a kind of simple structure, existing anti-seismic performance, the foam metal LED for having heat dispersion again dissipates
Hot device device.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：
A kind of foam metal LED radiator device, including main structure body, the main structure body include the radiator of bottom,
The aluminium base using heat conduction gemel connection is provided with radiator, is welded on aluminium base on LED base, is set on the aluminium base
Protective cover is equipped with, radiating block is provided between protective cover and aluminium base；The radiator is a metal dish, is set inside metal dish
Cavity is equipped with, metal dish sets hole with aluminium base link position, and hole penetrates internal cavities with outside.
Preferably, the radiator uses metallic aluminium and magnesium metal to use mass ratio as 1：The mixing material system of 1 ratio
Form.
Preferably, the radiating block is internally provided with multiple tiny holes.
Preferably, directly make that interface electrode is heat sink, insulating barrier on the aluminium base in the form of a film, reduce internal heat
Heavy thermal resistance.
Preferably, the cavity inside is provided with fan.
The beneficial effects of the invention are as follows：
The foam magnesium aluminium radiator that the foam metal LED radiator of the present invention is made using a certain proportion of aluminium and magnesium is both full
The shock attenuation needs of sufficient LED on the rolling stock, meet its cooling requirements again, and through-hole foamed metal is metal solid and hole
The complex of gap, its huge specific surface area and good trafficability performance cause when fluid from its hole by when have very
Big heat exchange area.

Link position sets hole, and hole penetrates internal cavities with outside.
Preferably, the radiator uses metallic aluminium and magnesium metal to use mass ratio as 1：The mixing material system of 1 ratio
Form.
Preferably, the radiating block is internally provided with multiple tiny holes.
Preferably, directly make that interface electrode is heat sink, insulating barrier on the aluminium base in the form of a film, reduce internal heat
Heavy thermal resistance.
Preferably, the cavity inside is provided with fan.
Wherein the present invention using through-hole foamed metal be metal solid and hole complex, its huge specific surface area and
Good trafficability performance cause when fluid from its hole by when with very big heat exchange area.Metal material is good
Heat conductivility enables heat to be more uniformly conducted into inside metal solid so as to be spread faster.If in forced convection
Under the conditions of, fluid caused complicated turbulent motion in porous metals will promote the exchange of heat
