Description
Technical field
The present invention relates to a kind of radiator, especially relate to a kind of LED radiator.
Background technology
Existing LED lamp generally comprises LED light source, heat transfer sheet and radiator, LED light source comprises aluminium base and is laid in the LED illuminating circuit on the front of aluminium base, heat transfer sheet is fixedly installed on aluminium base, fit in the bottom surface of heat transfer sheet and the back side of aluminium base, radiator comprises heat-radiating substrate and groups of fins, the bottom surface of heat-radiating substrate and the end face of heat transfer sheet are fitted, groups of fins is made up of multiple fin be disposed on the end face of heat-radiating substrate, forms the heat dissipation channel of radiator between every adjacent two panels fin.When LED light source is luminous, the heat that LED produces is delivered on heat transfer sheet by aluminium base, heat is delivered on the heat-radiating substrate of radiator by heat transfer sheet again, then be delivered in groups of fins, heat dissipation channel finally by radiator is delivered in air, reaches the object of LED light source being carried out to radiating and cooling thus.
When mounted LED lamp tool, LED illuminating circuit, aluminium base, heat transfer sheet and radiator are according to order arrangement from top to bottom, because the end face of heat-radiating substrate bottom surface and heat transfer sheet is fitted, the below of heat dissipation channel is closed, upper and lower air communication channel is not formed in heat dissipation channel, when heat is passed in radiator, the rear density of air heat absorption in heat dissipation channel reduces and raises leaves heat dissipation channel, the air that below heat dissipation channel, temperature is lower but cannot enter in heat dissipation channel, the heat of radiator is made to be difficult to dissipate, radiating effect is very poor, thus cause LED light source still to work in high temperature environments, reduce the service life of LED light source.
Summary of the invention
Technical problem to be solved by this invention is to provide one can form upper and lower air communication channel, the LED radiator of good heat dissipation effect.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of LED radiator, comprise heat radiation rack and groups of fins, described groups of fins is made up of multiple fin, described multiple fin are disposed at least one side of described heat radiation rack, heat dissipation channel is formed between every adjacent two panels fin, the arragement direction of described fin is vertical with the short transverse of described heat radiation rack, the bottom of described fin exceeds bottom one segment distance of described heat radiation rack, when in delivered heat to described heat dissipation channel, the rear density of air heat absorption in heat dissipation channel reduces and raises leaves heat dissipation channel, the air that temperature below heat dissipation channel is lower enters in heat dissipation channel, go round and begin again.
Cavity is provided with in described heat radiation rack, described cavity is built with cooling fluid, the evaporating temperature of described cooling fluid is 40-60 degree, when cooling fluid heating temperature is increased to evaporating temperature, described cooling fluid becomes gas and rises, and described gas transfer heat gives the side of described heat radiation rack, the side of described heat radiation rack transfers heat to described fin, now, the temperature of described gas is reduced to below evaporating temperature and becomes liquid and fall back to described cavity bottom, goes round and begins again.
Metallic sponge is provided with in described cavity.
Be provided with multiple dividing plate in described cavity, described cavity is divided into multiple region by described dividing plate, is provided with metallic sponge in the region described in each.
Described metallic sponge is loose structure.
Compared with prior art, the invention has the advantages that and comprise heat radiation rack and groups of fins, groups of fins is made up of multiple fin, multiple fin is disposed at least one side of heat radiation rack, heat dissipation channel is formed between every adjacent two panels fin, the arragement direction of fin is vertical with the short transverse of heat radiation rack, the bottom of fin exceeds bottom one segment distance of heat radiation rack, when in delivered heat to heat dissipation channel, the rear density of air heat absorption in heat dissipation channel reduces and raises leaves heat dissipation channel, the air that temperature below heat dissipation channel is lower enters in heat dissipation channel, go round and begin again, the heat dissipation channel of up/down perforation makes the air circulation near fin, improve the effect of heat radiation,
When being provided with cavity in heat radiation rack, cavity is built with cooling fluid, and the evaporating temperature of cooling fluid is 40-60 degree, when cooling fluid heating temperature is increased to evaporating temperature, cooling fluid becomes gas and rises, gas transfer heat is to the side of heat radiation rack, and the side of heat radiation rack transfers heat to fin, now, the temperature of gas is reduced to below evaporating temperature and becomes liquid and fall back to cavity bottom, go round and begin again, improve the heat-transfer effect of radiator, reduce the temperature difference between LED light source and fin;
When being provided with metallic sponge in described cavity, metallic sponge can adsorb cooling fluid;
When being provided with multiple dividing plate in cavity, cavity is divided into multiple region by dividing plate, when being provided with metallic sponge in each region, cooling fluid is distributed in regional under the absorption of metallic sponge, even if radiator tilts, cooling fluid also can not flow to the lower one end of heat radiation rack, causes radiator heat-dissipation effect uneven;
When metallic sponge has loose structure, metallic sponge can adsorb cooling fluid better.
