Description
Technical field
The utility model relates generally to heat sink technology field, is specifically related to a kind of radiator with helix fin.
Background technology
At present, traditional fansink designs being applicable to the electronic equipment such as solar panel and LED is honeycomb, column, cylindrical shape and finned cylindrical shape.By the form of heat transfer and thermal convection, the heat of the electronic equipment such as solar panel and LED is delivered in air to reach the effect of heat radiation.But under guarantee heatsink weight unlikely too high condition, honeycomb and pole-shaped radiator constrain the heat-sinking capability of radiator respectively due to the restriction of heat transfer cross-sectional area and heat convection area; Cylindric and finned cylindrical shape makes moderate progress in these two aspects, but heat loss through convection and heat conducting and radiating also do not match the best.Under the condition of the not obvious reduction of radiator heat capacity, the heat loss through convection area increasing radiator can also be continued, thus improve the radiating efficiency of radiator further.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of radiator with helix fin, heat transfer cross-sectional area and the heat convection area of radiator can not only be improved, and radiator heat loss through convection and heat conducting and radiating can be made to reach better mating, can while guarantee radiator heat capacity, the heat loss through convection area of further raising radiator, and be more conducive to the convection current of radiator ambient air.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of radiator with helix fin, comprise cylinder and fin, described cylinder is cylindrical, there is in the middle part of it central through hole axially running through cylindrical two ends, described cylinder and described central through hole coaxial line, described fin in the form of sheets, described fin is provided with multiple, multiple described fin is with the evenly spaced periphery being arranged on described cylinder of equal angular, fin described in every sheet is spirally extended to the other end of described cylinder around the axis of described cylinder from one end of described cylinder, and the two ends of fin described in every sheet and the axis of described cylinder in the same plane, described fin is connected as a single entity by injection moulding and described cylinder.
The beneficial effects of the utility model are: this fansink designs scheme can not only improve heat transfer cross-sectional area and the heat convection area of radiator, and radiator heat loss through convection and heat conducting and radiating can be made to reach better mating, can while guarantee radiator heat capacity, the heat loss through convection area of further raising radiator, and be more conducive to the convection current of radiator ambient air.
On the basis of technique scheme, the utility model can also do following improvement.
Further, the diameter of described cylinder is 9mm, and length is 20mm.
Further, the diameter of described central through hole is 3mm.
Further, the width of described fin is 5mm, and thickness is 0.5mm.
Further, the angle of inclination on the surface of described fin and described cylinder is 45 °.
Further, the angle of the axis of described fin and described cylinder is 40 °.
Further, the quantity of described fin is 24.
Opening between spiral helicine fin is increasing from inside to outside, be conducive to cross-ventilation, enhance heat convection effect as calculated, the radiator of this band helical form fin is compared with the radiator of the non-helical fin of band of the same race, its heat convection surface area adds 6 percent, and thermal capacity also increases to some extent.So both ensure that radiator leans on the thermal capacity needed for heat conducting and radiating, turn increase radiator by the convective surface area needed for thermal convection heat radiation.
