Abstract
The utility model provides a heat dissipation wind wheel for a petrol power generator and relates to a generator structure. The heat dissipation wind wheel for the petrol power generator comprises a wheel disk and arc-plate vanes, and is characterized in that the radial-direction inner edge of each arc-plate vane extends toward the outer surface of a ring cone body of a wheel disk in the radial direction so that an arc-plate body is formed in a one-piece manner, and each lengthened arc-shaped plate vane from the outer surface of the ring cone body to the external edge of the wheel disk is formed. The heat dissipation wind wheel for the petrol power generator has the advantages that the lengthened arc-shaped plate vanes produce complete squeezing pressure to air existing in space of the wheel disk, negative pressure is increased to accelerate an air flow speed, and air-cooling heat-dissipation effect is good.
Description
Technical field:
The utility model relates to electric generator structure, particularly a kind of gasoline engine generator heat radiation wind wheel.
Background technique:
Gasoline engine generator front-end of spindle and petrol engine are in transmission connection, and rear-end of spindle portion is mounted with the heat transmission wind wheel.Wind wheel is made up of wheel disc, blade.Wheel disc is shaped as cavity loop cone of circle disjunctor extension in the stepped ring forging dish; Ring cone upper brace central authorities are provided with center through hole; Be used to be sleeved on generator main shaft rear end cylindrical; The wheel disc upper surface is uniformly distributed with several vertical upright arc plate blades that extend, and arc plate blade radial outer is in stepped ring forging dish outer, and the edge is on the radius of stepped ring forging dish middle part in the arc plate blade radial.When main shaft rotates; The blade high speed rotating makes interlobate air outwards squeezed by arc plate, produces the centrifugal force air-flow and effluxes, and blade and blade front space thereof produce negative pressure thus; It is air-cooled to make motor front cover air-flow get into rotor, reaches electric machine rotor heat radiation effectiveness.
During this wind wheel rotation edge in the blade radial is not produced direct displacing pressure between the ring cone, so do not make full use of the row pressure power of blade, radiating efficiency is not high.
Summary of the invention:
The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of gasoline engine generator heat radiation wind wheel is provided.
The scheme of the utility model is: comprise wheel disc, arc plate blade; It is characterized in that: along to the ring outer surface of cone of wheel disc disjunctor extension arc plate body radially, form in each arc plate blade radial from the lengthening arc plate blade of ring outer surface of cone to wheel disc outer.
The advantage of the utility model is: lengthened vanes has air to the institute of taking turns disk space and produces comprehensive displacing pressure, and intensified negative pressure increases air-flow velocity, and the wind-cooling heat dissipating effect improves.
