Description
Technical field
The utility model relates to a kind of radiator, especially relates to a kind of LED radiator.
Background technology
LED illumination and general lighting have obvious superiority, and LED illumination is more efficient and energy-conservation, and illuminating effect is better than the illumination of ordinary lamp and lantern far away.Along with the growth requirement of society, LED illumination industry, civilian in obtain and popularize more widely.And existing LED illumination Shortcomings in heat radiation, what have only considered heat conducting and radiating, what have only considered thermal convection current heat radiation, what have only considered heat loss through radiation, do not consider each factor, make the radiating effect of LED not good, reduce the LED illumination life-span to a great extent, limit the range of application of LED.In order to LED illumination can be applied more widely, LED illumination heat dissipation problem then becomes the anxious problem treating effectively to solve.
Utility model content
The purpose of this utility model is exactly provide a kind of LED radiator of good heat dissipation effect to overcome defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of LED radiator, is characterized in that, described LED radiator is on the whole in hexahedron, and wherein one side hollow out forms the cavity of outside one side opening, and this cavity back side is cooling mechanism.
Described cooling mechanism is made up of the fin of three parts, and wherein lower heat sink is made up of the vertical fin of low wide and up narrow draught deflector and these draught deflector both sides; Wherein middle part fin is bent upwards until vertically gradually from fin both sides in arcuation; Its middle and upper part fin connects with the upper end of middle part fin and keeps vertically moving towards.
Described draught deflector by under the keeping out the wind of cross section rectangle piece and cross section be trapezoidal keep out the wind upper piece form, described in the keep out the wind upper surface of lower piece and described upper piece the lower surface that keeps out the wind be same surface.
Described middle part fin is made up of jointly multistage fin, retains setting spacing, form air convection groove between adjacent two sections of fin.
Described top fin is made up of jointly multistage fin, retains setting spacing, form air convection groove between adjacent two sections of fin.
Spacing between each adjacent two sections of fin is identical.
Described LED radiator is the radiator be made by Heat Conduction Material ZL102.
Described LED radiator surface sand-blasting is also coated with insulating heat-conductive paint.
Also heat-conducting medium layer can be provided with in described cavity.
The cross section of described fin is trapezoidal, and from thermal source, limit is narrow gradually outward.
Compared with prior art, the utility model has considered the thermal conductivity of heat sink material, heat eliminating medium, area of dissipation, the ingenious utilization of profile control thermal convection current heat radiation.

Embodiment
As shown in Figure 1, a kind of LED radiator, described LED radiator is on the whole in hexahedron, and wherein one side hollow out forms the cavity of outside one side opening, and this cavity back side is cooling mechanism.Described cooling mechanism is made up of the fin of three parts, and wherein lower heat sink is made up of the vertical fin of low wide and up narrow draught deflector and these draught deflector both sides; Wherein middle part fin is bent upwards until vertically gradually from fin both sides in arcuation; Its middle and upper part fin connects with the upper end of middle part fin and keeps vertically moving towards.
Described draught deflector by under the keeping out the wind of cross section rectangle piece and cross section be trapezoidal keep out the wind upper piece form, described in the keep out the wind upper surface of lower piece and described upper piece the lower surface that keeps out the wind be same surface.Described middle part fin is made up of jointly multistage fin, retains setting spacing, form air convection groove between adjacent two sections of fin.Described top fin is made up of jointly multistage fin, retains setting spacing, form air convection groove between adjacent two sections of fin.Spacing between each adjacent two sections of fin is identical.Fig. 1 depicts the air-flow trend graph of air through fin.
As shown in 2 figure, during application, LED lamp structure composition is made up of LED radiator 1, LED lamp panel 2, LED protective cover 3.In Fig. 3, between LED lamp panel 2 and LED radiator 1, be lined with interface Heat Conduction Material 4, then use securing member fastening.LED protective cover is also used securing member to be fastened on radiator, between with sealing ring sealing, the degree of protection after installing can arrive IP67.LED needs vertically to install as shown in fig. 3 when normal use as far as possible, guarantee the Natural Heat Convection of air, the area of dissipation of radiator itself is large, material pyroconductivity is high, can guarantee there is better radiating effect than common radiator, improve LED and obtain service life.
