Description

A kind of heat abstractor efficiently

Technical field

The present invention relates to the heat abstractor of light fixture, electronics, electrical equipment etc., refer to a kind of heat abstractor efficiently especially.

Background technology

The LED light fixture is because of being extensive use of that it is energy-conservation, efficient, environmental protection more and more is subjected to people, development along with society, demand to the LED light fixture is increasing, but problems such as the light efficiency of LED light fixture is low, light loss is big, light decay is fast, the life-span falls short of are appointed and are not obtained fine solution, and the heat radiation of LED light fixture guarantees the light fixture light decay just, prolongs the main difficult problem of lamp life.Extend on electronics, the electric equipment products, the heat dissipation problem that high power brings exists equally, also is one of reason of electronics, the accelerated ageing of electrical equipment original paper.

Existing heat dissipation technology mainly contains following three kinds of modes:

1, by fan heat energy directly is diffused in the air, forms natural heat dissipation, but the stability of fan is difficult to guarantee; Fan is again electrical equipment independently, self need of work power consumption, also super only 10000 hours its life-span.

2, adopt metal material as with processing backs such as section bar, fin, car aluminium as radiator, but it passes heat by metal and looses in air, heat dispersion is not good enough, volume is big, heavy, cost is high, energy consumption is big.

3, adopt the nonmetallic materials heat radiation, for example: graphite flake, heat radiation lacquer, heat radiation oil, plastic cement, forming gas etc., but actual heat dispersion is relatively poor, and cost is very high, is difficult to form large-scale production, and applied environment has limitation.

Summary of the invention

For addressing the above problem, the invention provides a kind of simple in structurely, by the self structure characteristics, realize passing efficiently heat radiation, with the device of the heat radiation that realizes light fixture, electronics, electrical equipment.

For achieving the above object, the technical solution used in the present invention is: this heat abstractor is formed by connecting by two-layer above fin, and described fin is layering, and is fixedly connected with one heart, and this fin is horn-like, and regular distribution has ventilation hole thereon.

The bell-mouthed area of dissipation of described fin is 5～50 times of area of dissipation of loudspeaker bottoms, and this horn mouth is that radius is the anti-r opening of 20～300mm.

The height of described fin is successively increased progressively by bottom fin to top fin, and its bell-mouthed radius is successively successively decreased by bottom fin to top fin.

The ventilation hole of described fin is extended near bell-mouthed edge by the fin bottom, and there is substrate the lower end of the fin of bottom.

Ventilation hole on lower floor's fin of described fin and the ventilation hole on the fin of upper strata are dislocatedly distributed.

Heat pipe is equipped with at the center of described fin, and this heat pipe is circular-arc, and its external part is towards the bending of fin direction.

It is oblate that the external part of the heat pipe of described fin is, and its opening part is extended with dust cap, and this dust cap is the great circle arcuation, with opening formation one thermovent towards fin of heat pipe.

The heat pipe of described fin is made by the superconduction hot material.

Described fin adopts aluminium, aluminium alloy, zinc magnesium alloy, plumbous magnesium alloy, plastic material or other heat sink materials to make, and its external spray has the heat radiation lacquer, and it is carried out photocatalyst handle.

Beneficial effect of the present invention is: the horn-like heat sink design of layering, by the biography thermal diffusivity of self, with the ventilation hole above it, make light fixture, electronics, the heat energy that sends during work such as electrical equipment forms hot eddy current, collide mutually between hot eddy current and the air and got out by lower floor's ventilation hole, because the alternate setting of the ventilation hole between layer and the layer and the biography thermolysis of fin, make the flow spiral that is got out by lower floor rise, when arriving top layer, form the air-flow of tornado, eddy current is with light fixture fast, electronics, the heat that electrical equipment etc. distribute sheds rapidly, and it is dispersed in the air; The heat pipe at fin center, because of its superior heat conductivity, the heat at thermal source place can be concentrated fast derives, fast the heat of deriving is passed diffusing in air by means of formed hot eddy current under the horn-like heat abstractor operating state, add the heat radiation lacquer of heat abstractor outside, more improve the heat dissipation of fin, to realize the high-efficiency heat conduction heat radiation, guaranteed the normal useful life of light fixture, electronics, electrical equipment etc.; Heat abstractor can reach waterproof, protection against the tide, dustproof by the photocatalyst PROCESS FOR TREATMENT, exempts to clean non-maintaining performance to reach.
