Embodiment
With reference to Figure of description 1, it shows a kind of wind-driven generator radiator structure, comprise housing 1, also comprise the ventilated rib 3 that axially is arranged on one group of hollow on housing 1 outer surface, and one axially be arranged on the housing and be communicated in the ventilation duct 2 of described ventilated rib 3, and this ventilation duct is provided with the air inlet 5 that is used to connect source of the gas; Wherein, described ventilated rib side is provided with venthole 6 arrays, and the profile of the axis of venthole and described housing intersects.
Ventilated rib is circumferentially uniform around housing, and distribution density can be with reference to the density with the shells radiating ribs, and its density is equivalent to about 1/2 of radiating ribs density, is the best with 1/2.The length of radiating ribs can be consistent with the length of housing in theory, also can slightly be shorter than shell length, Yi Bian reserve one section under the installment state, is convenient to assemble the setting with ventilation duct.Preferably, leave a piece housing between the end face of the two ends of described ventilated rib and housing.
Further, on a piece housing that leaves, be provided with and be provided with radiating ribs 4 uniformly, to improve radiating efficiency.
Structure about ventilated rib can adopt existing pipeline structure, as long as venthole meets the demands, selects flexibility very strong.This programme provides a kind of preferable structure, and just the cross section of described ventilated rib is an isosceles trapezoidal structure, and the trapezoidal end entad of these isosceles be shorter than the centrifugal end, be convenient to install setting with venthole.Because housing is bigger, isosceles trapezoidal structure also can be thought approximate construction, can make the less arc of ratio of curvature.
Preferably, the axis normal of described venthole helps reducing flow resistance in the waist of described isosceles trapezoid.
Can be provided with one for air inlet, be more than two but preferable mode then is described air inlet, and along circumferentially evenly distributing of described housing, the air-flow that can distribute relatively equably reaches better cooling effect.If be provided with two, these two air inlets then are provided with axisymmetrically.
