Abstract
The invention discloses an LED radiator comprising a radiating frame and a radiating fin group. The radiating fin group is composed of a plurality of radiating fins which are arranged on at least one side face of the radiator at intervals, a radiating channel is formed between every two adjacent radiating fins, the layout direction of the radiating fins is vertical to the height direction of the radiating frame, and the bottom end of each radiating fin is a certain distance higher than the bottom end of the radiating frame. When heat is transmitted to the radiating channels, air, after absorbing the heat, inside the radiating channels is reduced in density and rises prior to flowing out of the radiating channels, and air lower in temperature and located under the radiating channels flows into the radiating channels in circles. The LED radiator has the advantages that the radiating channels communicated from top to bottom allow air nearby the radiating fins to circulate, so that radiating effect is improved.

Existing LED light fixture 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, the bottom surface of heat transfer sheet and the laminating of the back side of aluminium base, radiator comprises heat-radiating substrate and groups of fins, the bottom surface of heat-radiating substrate and the laminating of the end face of heat transfer sheet, groups of fins is comprised of the fin on a plurality of end faces that are disposed on heat-radiating substrate, forms the heat dissipation channel of radiator between every adjacent two fin.When LED light source is luminous, the heat that LED produces is delivered on heat transfer sheet by aluminium base, heat transfer sheet is delivered to heat on the heat-radiating substrate of radiator again, then be delivered on groups of fins, finally the heat dissipation channel by radiator is delivered in air, reaches thus the purpose of LED light source being carried out to radiating and cooling.
When the mounted LED lamp tool, the LED illuminating circuit, aluminium base, heat transfer sheet and radiator are arranged according to order from top to bottom, end face laminating due to heat-radiating substrate bottom surface and heat transfer sheet, the below of heat dissipation channel is closed, do not form upper and lower air communication channel 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 lower air of heat dissipation channel below temperature but can't enter in heat dissipation channel, make the heat of radiator be difficult to dissipate, radiating effect is very poor, thereby cause LED light source still to be operated under hot environment, reduced the service life of LED light source.
Summary of the invention
Technical problem to be solved by this invention is to provide and a kind ofly can forms 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 comprised of a plurality of fin, described a plurality of fin is disposed at least one side of described heat radiation rack, form heat dissipation channel between every adjacent two 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 heat transfers in described heat dissipation channel, the rear density of air heat absorption in heat dissipation channel reduces and raises leaves heat dissipation channel, the lower air of temperature of heat dissipation channel below enters in heat dissipation channel, go round and begin again.
Be provided with cavity in described heat radiation rack, in described cavity, cooling fluid is housed, the evaporating temperature of described cooling fluid is the 40-60 degree, when the cooling fluid heating temperature is increased to evaporating temperature, described cooling fluid becomes gas and rises, and described gas transfer heat is given 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.
