Abstract
Disclosed is an air-cooling synchronous generator, which belongs to generator field. The air-cooling synchronous generator mainly comprises a generator body, an air cooler, a shaft-driving fan; the top of the generator body is provided with the air cooler, the air cooler comprises a cooling tube and a tube-outside wind cavity; the shaft of the generator body is provided with a fan for air circulation inside the generator, the air cooler is arranged with a plurality of cooling tubes, the tube-outside wind cavity and the generator body form the an internal wind path of the generator, the cooling tube and an axial fan form an external wind path of the generator, another fan which provides power for the external wind path is arranged at the non-driving end of a generator rotor. The air-cooling synchronous generator has good cooling performance and reliable operation, and can be widely used to the desert, the coal mine and other severe environments.
Description
Technical field
The utility model belongs to electrical generator fields, specifically is meant a kind of new electric generator structure that utilizes air that generator is cooled off.
Background technology
Prior motor cooling is by self machine operation, utilizes the air natural cooling.Because it is the diversification day by day of motor application field, increasing to degree of protection height, the simple motor demand of the type of cooling.And the motor of air cooling structure form not only the degree of protection height, service life is long, maintenance cost is low, simple in structure, and can satisfy the various working instructions for use, the abominable area of environment particularly is as oil field, desert and drilling platforms.And to the use of above-mentioned regional motor, the air cooling structure effect of ordinary construction is not good especially, influences useful life easily, needs the particular design air cooling system.
Summary of the invention
The utility model has designed a kind of new air cooled generator, and it is made up of motor body, aerial cooler, three parts of axle band fan, and aerial cooler is loaded on the motor top, is made of cooling water pipe and pipe exogenous wind chamber.Pipe exogenous wind chamber communicates with the motor internal wind path, the common interior wind path that forms motor-aerial cooler system, motor anti-drive end axle band fan end communicates with extraneous air, and leg around the generator anti-drive end axle band fan and cooling water pipe are connected to form the outer wind path of heat exchange.When motor rotation, fan by motor internal is sent hot-air into air cooling organ pipe exogenous wind chamber, the axle band fan that is positioned at the motor anti-drive end simultaneously sucks the cold air in the external world and send into the cooling pipe of cooler, cold and hot air carries out sufficient heat exchange by the conduction of cooling pipe, reenter motor internal by heat exchange with the hot-air cooling and from motor anti-drive end window, going round and beginning again forms interior circulation.
Good cooling results of the present utility model, reliable, can be widely used in the adverse circumstances described in the background technology.
