Abstract

The utility model discloses a perforated multi-facet radiator, which comprises a plurality of radiating sheets that are connected at the periphery and one surface of a heat-transferring base plate. The plurality of non-parallel radiating sheets are staggered with one another to form a plurality of overflowing through holes, and concave/convex three-dimensional surfaces are arranged on the radiating sheets at periphery of the overflowing through holes. The through-holes structure well overcomes shortcomings that dust is easily accumulated in the clearance between radiating fins at the surface of the traditional radiator, and the long-term using can severely affect the radiating effect; the concave/convex three-dimensional surface is arranged on the radiating sheets at the periphery of the through hole so as to increase contact area between the radiator and the air, in this way, compared with the radiator with the same volume and weight, the radiating area for the perforated multi-facet radiator can be increased by 30% or more.

Description

The three-dimensional radiator of a kind of perforation multiaspect

Technical field

The utility model relates to a kind of radiator, the definite three-dimensional radiator of a kind of perforation multiaspect of utilizing cross-ventilation to improve radiating effect of saying so.

Background technology

From being used for illumination, heat dissipation problem is restricting the development and the application of great power LED always, more common in the market great power LED adopts aluminium alloy to make the form that heat transfer substrate combines with radiating fin with radiator, this radiator has simple in structure, stable performance, advantages such as Maintenance free and being widely used, this kind mode has become the main flow of LED heat radiation, but it is more that this radiator consumes aluminium, and easy accumulation dust odd job between radiator upper surface radiating fin, to have a strong impact on radiating effect for a long time in the past, generation for fear of this situation, some producer adds shell again on radiator, really do the problem that to evade radiator collection ash like this, but radiator has been put on one deck overcoat from the beginning and has been hindered distributing of heat.

Summary of the invention

For addressing the above problem, thereby the utility model provides a kind of opening that was provided with on radiator to utilize cross-ventilation to improve the three-dimensional radiator of perforation multiaspect of radiating effect.

The technical solution of the utility model is as follows:

The three-dimensional radiator of a kind of perforation multiaspect, being connected in heat transfer substrate by some fin simultaneously constitutes all around and wherein, wherein nonparallel some fin are interlaced, and interlaced fin surrounds and forms a plurality of openings of crossing, and overcurrent bore periphery fin is provided with the stereo concave-convex face.

Described radiator is made by copper, aluminium, magnesium high-thermal conductive metal material or copper, magnesium, the contour heat conduction alloy material of aluminium.

Described fin is plane or curved-surface structure, on the plane or the two sides of curved surface fin establish arc, triangle, multiaspect shape, sheet or irregular male and fomale(M﹠F).

The described opening of crossing forms by some fin are interlaced, and its normal section can be the combination of one or more forms in triangle, quadrangle, polygon or the irregular shape.

Described heat transfer substrate comprises one at least, and it simultaneously is an installed surface, and another side is connected to form integral body with fin around reaching.

Good effect of the present utility model: the utility model radiator adopts perforation multiaspect stereochemical structure, the through hole grid forms a plurality of flow channels, the air themperature of radiator periphery can increase when light fixture point brightness temperature raises, frivolous hot-air can rise, hot-air after the rising will form negative pressure at the radiator periphery makes colder air fill up, so just formed the exchange of heat, the formation cross-ventilation that so goes round and begins again improves radiating efficiency, this through-hole structure has well solved and has accumulated the dust odd job between traditional heat-dissipating device surface radiating fin easily simultaneously, the long-term drawback that has a strong impact on radiating effect of using; Increase the stereo concave-convex face to increase the contact area of radiator and air on the bore periphery fin, so, the radiator heat-dissipation area of equal volume and weight can increase more than 30%.

The specific embodiment

Shown in Fig. 1～4, fin is plane or curved-surface structure, on the plane or the two sides of curved surface fin establish arc, triangle, multiaspect shape, sheet or irregular male and fomale(M﹠F).

Shown in Fig. 5,6, the three-dimensional radiator of a kind of perforation multiaspect, be connected in heat transfer substrate (1) by some fin (2) and reach wherein one side formation all around, wherein nonparallel some fin are interlaced, interlaced fin surrounds and forms a plurality of openings (3) of crossing, and overcurrent bore periphery fin is provided with the stereo concave-convex face to increase area of dissipation.

Above-mentioned radiator can be made by copper, aluminium, the contour thermal conductive metallic material of magnesium, also can adopt copper, magnesium, the contour heat conduction alloy material of aluminium to make.

Cross opening and formed by the interlaced encirclement of some fin, its normal section can be the combination of one or more forms in triangle, quadrangle, polygon or the irregular shape.

The radiator heat transfer substrate comprises one at least, its size and quantity are provided with flexibly according to size and quantity that light source and light-distribution lens are installed, radiator simultaneously is an installed surface, installed surface is generally smooth flat, also can be set to the encapsulation region that pit or direct packaging LED chips are installed, the radiator another side is connected to form integral body with fin around reaching.

For planar fins intersects front view, is that two groups of parallel fin intersect vertically as Fig. 7 among the figure, can be two groups of above non-perpendicular intersecting during practical application; As Fig. 8 is the surface intersection front view, and male and fomale(M﹠F) is set on the above-mentioned legend midplane curved surface fin as required flexibly increases area of dissipation.
