Abstract
The invention discloses a cooling structure of an alternating-current generator flywheel. The cooling structure comprises a flywheel and a fan arranged on one side of the flywheel, wherein a plurality of hollowed parts are formed on the fixed wall of the fan for locking the flywheel, and a cooling blade is formed in each hollowed part. Therefore, when the flywheel rotates together with the fan, besides the radially blown airflow generated by the radiating blades on the periphery of the fan, the axially blown cooling airflow generated by using the cooling blades is blown to the surface of the flywheel so as to effectively promote the cooling and radiating effects on the flywheel.

In existing flywheel gear structure, although its flywheel combines fan, when fan is driven in rotation in company with flywheel, produce the heat sinking function to engine chamber, but this fan is the radiating airflow producing radial blowout, blow less than flywheel, and flywheel be driven in rotation produce heat and the coiling group work be located in flywheel produces heat etc., all cannot effectively be distributed, in addition flywheel nothing preferably heat-dissipating structure itself, so that temperature drift during flywheel running, and affect its task performance.
[summary of the invention]
Main purpose of the present invention is the cooling construction providing a kind of alternating-current generator flywheel, whereby, improves the shortcoming that heat dissipation that existing alternating-current generator flywheel cooling construction provides is not good.
Object is taken off before reaching, the cooling construction of the alternating-current generator flywheel designed by the present invention is the fan comprising a flywheel and be mounted on this flywheel side, described fan is provided with several radiator shutter, wherein, this fan has a fixation wall, this fixation wall is formed several hollow-out parts towards flywheel side, in each hollow-out parts, form cooled blade.
The present invention designs by aforementioned flywheel cooling construction, be characterized in: when flywheel is driven in rotation together with fan, this fan produces the radial air-flow blowed divided by the radiator shutter of outer peripheral edges, in order to be provided the radiating airflow of engine necessity by wind-guiding cover cap, the present invention further utilizes the cooled blade in its fixation wall hollow-out parts to produce the cooling blast axially blowed and blows to flywheel surface, effective lifting is to the cooling heat dissipation usefulness of flywheel, reduce the temperature of flywheel rotary motion, make this alternating current generator maintain better state of exerting oneself.
An of the present invention object makes the outer peripheral face of this flywheel form number radiating fin further, in order to expand flywheel heat-delivery surface, and rotates the effect that can have fan blade generation radiating airflow concurrently in flywheel.
