Abstract
An engine component cooling system and apparatus, at least one fan and a cover are installed upon the engine component. The fan pulls cool air and force cool air through the component assembly to reduce the heat generated through operation, thereby optimizing operation and extending the useful life of the individual components and the assembly. In one example, a fan and a cover are installed on an alternator assembly so that the fan draws in and forces cool air through the rectifier, rotor, stator, and out through the front of the assembly. The cover prevents cool air from being lost and misdirected, while directing the cool air through the assembly.
Claims9
An alternator assembly, comprising:
- a housing having a front end, a rear end, a closed sidewall, a plurality of air inlets opening through the rear end, and a plurality of air outlets opening through the front end;
- at least one rotor and at least one stator disposed in the housing;
- a rotating shaft disposed in the housing, a portion of the rotating shaft extending outside of the housing beyond the front end;
- a pulley or gear rotatably coupled to the rotating shaft and disposed outside of the housing;
- and
- at least one fan rotatably coupled to the rotating shaft;
- wherein an axial air pathway is provided between the at least one stator and the closed sidewall, and wherein rotation of the shaft rotates the at least one fan thereby drawing air in through the plurality of air inlets, through the axial air pathway passed the at least one rotor and the at least one stator, and out through the plurality of air outlets.
