By optimizing the distance between fins and technological parameters of the corrugation, the heat exchange and heat radiation effects of the heat radiating fin, compared with the prior art, increase by 25% to 46%. With same heat radiating power, the weight of the corrugated radiating fin reduces by 10-18%, thereby effectively reducing the cost of raw materials.
Description
Technical field
The utility model relates to the device that electronic element radiating is used, and is specifically related to a kind of fin and is undulatory fin.
Background technology
High speed development along with science and technology, electronic equipments such as server, personal desktop computer, LED, refrigeration plant are in order to improve usefulness, electronic devices and components develop to the volume miniaturization gradually, but along with power improves constantly, its caloric value also increases thereupon, for this reason, the high fin of heat dissipation all is installed on these power components.With regard to present employed heat abstractor, wind-cooling heat dissipating is the current heat abstractor that is widely used, aluminium extruded and the welding procedures of adopting more, aluminium extruded is mainly used in the little components and parts radiating requirements of caloric value, size-constrained many, so that usefulness is low, and welding procedure can increase contact heat resistance, causes its heat transfer property obviously to descend.Except wind-cooling heat dissipating, water-cooling is another radiating mode commonly used, the fin fin that is sealed in the cavity adopts the machine-shaping of cutting one more, its contactless thermal resistance of one machine-shaping, heat transfer property is good, understand its heat radiation gear piece by fin patent before and be that the straight parallel shape arranges, because of fluid resistance between straight parallel shape structure arranged gear piece little, so that the heat exchange factor reduces, and performance can not fully be improved.
The utility model content
At above-mentioned deficiency of the prior art, the integral type ripple radiating fin that the utility model provides passes through the appropriate design to each technological parameter of radiating fin, has solved the problem of fin radiating effect difference.
In order to reach the foregoing invention purpose, the technical solution adopted in the utility model is: a kind of integral type ripple radiating fin is provided, it comprises radiating fin and the heat absorption end that connects as one, and described radiating fin integral body is bellows-shaped, and wave amplitude 2A is arranged between the 0.5mm-1.5mm; Spacing in the described radiating fin between each fin is arranged between the 0.2mm-1.0mm.
Preferably, the fin thickness of described radiating fin is arranged between the 0.1mm-0.3mm, and fin height is arranged between the 2mm-8mm, and wavelength is arranged between the 4mm-11mm.
Preferably, upper and lower surface is provided with the roughness of 0.6 μ m-1.6 μ m at the bottom of the described heat absorption.
Preferably, at the bottom of the described heat absorption be shaped as square or circular.
Preferably, be provided with installing hole at the bottom of the described heat absorption.
Preferably, described radiating fin and the material at the heat absorption end are copper and aluminium.
The beneficial effects of the utility model are: by the spacing of each fin of radiating fin and each parameters Optimization of ripple are designed, make the heat exchange of this fin and the corrugated fin of the relative prior art of radiating effect improve 25%-46%, meanwhile, equating under the heat radiation power, the weight saving of corrugated fin fin 10%-18%, reduced the cost of raw material effectively; This radiating fin can share related die, the development cost of having saved new die with former plain fin adding man-hour.

Wherein, 1, radiating fin; 2, the heat absorption end.
Embodiment
Extremely shown in Figure 5 as Fig. 1, this integral type ripple radiating fin material is copper or aluminium matter, it comprises: the heat absorption end 2 and radiating fin 1, the thickness at the end 2 of wherein absorbing heat is arranged between the 1mm-3mm, the height of radiating fin 1 is arranged on 2mm-8mm, the heat absorption end 2 and radiating fin 1 are integral structure, and the heat absorption ends 2 shape can be made into circle, square or other shapes.
For the ease of radiating fin 1 is sealed in the cavity, heat absorption can arrange similar hole slot structures such as installing hole at the end 2, can hole slot be set yet and adopt the mode of welding that its sealing is arranged in the cavity, in order to guarantee sealing, simultaneously need be at parameter requests such as the heat absorption ends 2 upper surface finish-milling processing roughness, flatnesses, the heat absorption end 2, fit tightly with euthermic chip for guaranteeing, the heat absorption ends 2 lower surfaces (chip contact-making surface) also need parameter requests such as finish-milling processing roughness, flatness, and the slightly degree of making of upper and lower surface is arranged between the 0.6 μ m-1.6 μ m; The length and width at the heat absorption end 2 are arranged in the 90mm; The length and width of radiating fin 1 are arranged in the 50mm, and the height of radiating fin 1 is arranged between the 2mm-8mm.
Radiating fin 1 parameter F t is that gear piece thickness, Sf are that fin step pitch, L are that corrugated fin wavelength, 2A are the corrugated fin wave amplitude; Wherein, the optimum thickness of Ft is 0.1mm-0.3mm in the water-cooled; Be conducive to heat exchange when Sf gets smaller value, but too small heat exchange and the resistance of also can having influence on can increase also, size the best is arranged between the 0.2mm-1.0mm; Be conducive to heat exchange when L gets the small value, same resistance also can increase, and size the best is arranged between the 4mm-11mm; The increase of 2A, the heat exchange factor of radiating fin 1 and resistance factor are just more big, and liquid resistance factor increase speed was more a lot of greatly than the heat exchange factor when wave amplitude was excessive, will influence heat exchange, be that heat can not spread out of or need large capacity motor fast, size the best is arranged between the 0.5mm-1.5mm.
The operation principle of this fin: the power component evolution of heat receives (carrying out heat exchange earlier) through the heat absorption ends 2 lower surface earlier, conduct to the low direction of temperature rapidly according to hot transfer principle heat, flowing liquid between a part of heat transferred fin belongs to the conduction of solid-liquid heat behind the heat absorption ends 2 reception heat; Another part heat is delivered to corrugated fin, belong to the solid interior conduction, and then be converted into the former solid-liquid thermal conductance, at this moment heat fully carries out will being passed effectively by the gap of the liquid in the cavity by 1 of radiating fin after the heat exchange, the power resources of working fluid are in motor, the heat that liquid is taken away cools the temperature to uniform temperature through water of radiation row, returns and circulates to realize heat exchange in the radiating fin gap.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also carry out some improvement to the utility model, these improvement also fall in the protection range of the utility model claim.
