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, heat transfer sheet, radiator is arranged successively in order from the bottom up, multiple groups of fins that radiator comprises heat-radiating substrate and is spaced by multiple fin, multiple groups of fins is arranged on the end face of heat-radiating substrate, fin linearly array distribution and all do not exceed the scope of heat-radiating substrate, heat dissipation channel is formed between adjacent two fin, the heat dissipation channel be located along the same line is interconnected, the setting direction of fin is parallel with the length direction of heat-radiating substrate, when mounted LED lamp tool, two ends on heat-radiating substrate width are generally provided with dividing plate, the heat dissipation channel being positioned at heat-radiating substrate two ends is closed by two dividing plates, fin all and divider upright.When LED light source is luminous, the heat that LED produces is delivered on heat-radiating substrate by heat transfer sheet, and heat is delivered on fin by heat-radiating substrate again, is delivered in air finally by groups of fins, reaches the object of LED light source being carried out to radiating and cooling thus.
But, because fin is all arranged in the scope of heat-radiating substrate, the below of the heat dissipation channel between fin is closed by heat-radiating substrate, 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, and the air that below heat dissipation channel, temperature is lower cannot be entered into heat dissipation channel by heat-radiating substrate obstruct, the heat of radiator is caused to be difficult to dissipate, radiating effect is very poor, the operating temperature of LED lamp can reach 80 DEG C-90 DEG C, in addition, because heat-radiating substrate two ends are provided with dividing plate, heat dissipation channel is closed by dividing plate, extremely difficult cleaning, and LED lamp is in outdoor environment for a long time, a large amount of dust foreign material are deposited in heat dissipation channel, these dust foreign material make the radiating effect of radiator poorer, LED light source is caused 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 and has Automatic clearance function, 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-radiating substrate and groups of fins, described groups of fins comprises the fin on multiple end face being disposed on described heat-radiating substrate, heat dissipation channel is formed between fin described in adjacent two, the end that described fin and described heat-radiating substrate are used for closing is parallel, one end that multiple fin is positioned at the same side is stretched out outside the edge of described heat-radiating substrate, when heat is sent to heat dissipation channel, after absorption of air heat in described heat dissipation channel, density reduces and raises to leave described heat dissipation channel, be arranged in the air that below the heat dissipation channel outside described cooling base, temperature is lower and enter heat dissipation channel, go round and begin again.
The end face that described fin stretches out the one end at heat-radiating substrate edge is all provided with groove, and the described groove of the same side is located along the same line, and is provided with baffle plate in the described groove of the same side.
The width of described baffle plate is not less than the degree of depth of described groove.
The outboard end of described groove is lower than the medial extremity of described groove.
The two ends of described fin all extend out to outside the edge of described heat-radiating substrate.
Compared with prior art, the invention has the advantages that fin is parallel for the end closed with heat-radiating substrate, one end that multiple fin is positioned at the same side is stretched out outside the edge of heat-radiating substrate, when heat is sent to heat dissipation channel, after absorption of air heat in heat dissipation channel, density reduces and raises to leave heat dissipation channel, be arranged in the air that below the heat dissipation channel outside cooling base, temperature is lower and enter 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, simultaneously due to heat dissipation channel and the ft connection of radiator, this radiator can reach the effect of cleaning automatically by rain drop erosion, avoid the accumulation of dust foreign material,
When the end face that fin stretches out the one end at heat-radiating substrate edge is all provided with groove, the groove of the same side is located along the same line, when being provided with baffle plate in the groove of the same side, the lower air of temperature runs into baffle plate in the process of heat dissipation channel and is obstructed supplementing to enter, then the middle part to heat dissipation channel is spread, make the radiating effect that whole radiator reaches evenly good, now, during LED lamp work, temperature can remain on 50 DEG C-60 DEG C, and radiating effect improves 20 DEG C-30 DEG C than original LED radiator;
When the width of baffle plate is not less than the degree of depth of groove, all air entering into heat dissipation channel can be guided to the middle part of heat dissipation channel by baffle plate;
When medial extremity lower than groove of the outboard end of groove, baffle plate is oblique to be arranged in groove, and baffle plate is away from one end of fin lower than the other end, and the air that the ramp way that baffle plate is formed makes temperature lower more easily enters in the middle of heat dissipation channel;
When the two ends of fin all extend out to outside the edge of heat-radiating substrate, make whole radiator Homogeneouslly-radiating, reach best radiating effect.
