Abstract

The invention relates to a fin-inserted radiator comprising a substrate and a plurality of radiating fins. A plurality of parallel grooves are arranged on the surface of the substrate. Each of the radiating fins includes a first side edge and a second side edge that is opposite to the first side edge; and the first side edges of the radiating fins are pressed in the parallel grooves. The radiating fins are perpendicular to the substrate. Besides, the radiating fins are in corrugated shapes; a plurality of wind guide grooves are formed on the surfaces of the radiating fins; and the wind guide grooves are extended from the first side edges of the radiating fins towards directions of the second side edges of the radiating fins. Because the surfaces of the radiating fins are arranged in corrugated shapes, heat radiation superficial areas of the radiating fins are increased; when wind passes through the radiator, fin surfaces can be better contacted. Moreover, the wind guide grooves are used to guide wind direction; therefore, when the wind passes through the radiator, the wind flows from the first side edges with high temperatures to the second side edges with low temperatures. An excellent heat radiation performance is realized on the condition that the provided radiator has a same appearance and same dimension as an ordinary radiator. Or on the condition that identical performances are ensured, the volume of the provided radiator is effectively reduced; therefore, the radiator is exquisite and beautiful as well as cost is lowered.

Description

A kind of fin-inserted radiator

Technical field

The present invention relates to a kind of radiator, especially, relate to the fin-inserted radiator that a kind of radiating effect is good.

Background technology

Along with the extensive use of electronic product, powerful electronic devices and components also get more and more, and it is also proposed higher requirement during operation to radiator.

Fin-inserted radiator is more common a kind of heat dissipation equipment, compares the heat radiation being usually used in high-power electronic component.Refer to Fig. 1, for the schematic perspective view of existing individual fin of fin-inserted radiator, Fig. 6 A, for existing fin-inserted radiator radiation air to schematic diagram, existing fin-inserted radiator comprises substrate 100 ' and fin 200 ', and its substrate 100 ' is close or be close to thermal source 300 ', and thermal source 300 ' is namely high-power electronic component usually, the fin 200 ' of existing fin-inserted radiator is located on substrate 100 ', and the quantity of fin and area can be arranged as required.Namely the heat that thermal source 300 ' produces is passed to fin 200 ' by substrate 100 ', blowing apparatus, be generally fan or air blast (not shown) is dried to fin-inserted radiator, heat on fin 200 ' just can be distributed in air quickly, so fin 200 ' temperature declines.Same process lasts carries out, and so just the heat in thermal source 300 ' can be shed, and the temperature of thermal source 300 ' is unlikely to Tai Gao and damages corresponding electronic devices and components.

Visible, the size of fin is one of influencing factor of radiating effect, and fin area is larger, can have more significant radiating effect, but the area of fin is subject to the restriction of equipment volume simultaneously, if excessive, is then unfavorable for the lighting of electronic equipment.How when area of dissipation is constant, alleviates the volume and weight of radiator as much as possible, can meet corresponding radiating effect again, is the direction being worth development.

In addition, this radiator structure shown in Fig. 6 A, heat concentrates on the place of fin 200 ' near substrate 100 ' usually, the too high normal use affecting electronic devices and components of temperature also mainly concentrates on the part of fin 200 ' near substrate 100 ', and fin 200 ' is relatively low away from the portion temperature of substrate, radiating efficiency is relatively low, consider that the heat transference efficiency of metal is much larger than air, if fin 200 ' can be made to be dispelled the heat all more equably on the respective sections, namely fin 200 ' is distributed to monoblock fin 200 ' near the even heat of substrate 100 ' part, also radiating effect can be improved comparatively significantly.

Summary of the invention

Main purpose of the present invention is the deficiency overcoming existing radiator, one is that radiating efficiency is not high, cannot more efficiently dispel the heat when volume is limited, two are fin close to thermal source part often temperature raise very fast, and the portion temperature of stow away from heat is not high, the whole area not making full use of fin carries out efficiently radiates heat.

A kind of radiator of the present invention, described radiator comprises a substrate and plural pieces fin, described substrate surface is provided with plurality of parallel groove, described fin comprises the second side of described first side relative to, a first side, the first side of described fin is pressed in described parallel slot, described fin and substrate are vertical setting, described fin is corrugated, surface is formed with a plurality of wind guide tanks, and described wind guide tank extends to the direction, second side of described fin from the first side of described fin.

By the surface of fin is set to corrugated, increase the cooling surface area of fin, make wind when by radiator, more can touch muscle sheet surface; And the direction of wind is guided further by wind guide tank, make wind when by radiator, flow to the low second side of temperature from the first side that temperature is high; Make it under identical overall dimension condition, there is more outstanding heat dispersion; Or under identical performance condition, effectively can reduce the volume of radiator, thus more small and exquisite, attractive in appearance and reduce the cost.

Preferably, described wind guide tank tilts evenly to be arranged at the surface of described fin, the angle of the first side of described wind guide tank and described fin 45 ° ± 5 °, described wind guide tank comprises a first side wall and one second sidewall, angle between described the first side wall and described second sidewall is 170 ° ~ 172 °, and the width of described wind guide tank is 10 ~ 15mm.
