Abstract
The utility model discloses an insulation and heat dissipation structure of an alternator back shell used for an automobile. The back shell has a fan drum structure, that is, the back shell is provided with an air inlet and an insulation and heat dissipation space. The utility model has the advantages that: owing to the back shell adopting the fan drum structure, when being installed and used, the air inlet of the fan drum faces to the fan of the automobile; therefore the motor has a better insulation and heat dissipation performance when being very close to the exhaust pipe of the motor and the wind produced by the fan of the automobile can be effectively guided into the fan drum, thus effectively controlling the temperature of the motor from rising and lengthening the service life of the motor.
Description
Technical field
The utility model is the heat insulation and radiator structure of a kind of vehicle alternator back cover.
Background technology
Existing vehicle alternator structure mainly comprises drive end cap assembly, brush cover assembly, stator, rotor, adjuster, rectifier bridge, belt pulley, the back case member formation that is linked and packed, the back cover that is adopted is the louvre structure, if the exhaust pipe of engine is very near apart from generator, then the temperature around the generator is very high, temperature has a direct impact the function of use of generator performance, adjuster and rectifier bridge by the vent of back cover, can cause shortening the useful life of generator.
Summary of the invention
The purpose of this utility model is, solves above-mentioned existing existing problem, and a kind of heat insulation and radiator structure of vehicle alternator back cover of heat insulation and perfect heat-dissipating is provided.
The utility model is achieved in that back cover is the air duct structure, and promptly back cover is provided with air inlet, and is provided with heat insulation and heat-dissipating space.
The utility model has the advantages that, because back cover adopts the air duct structure, make the position of the air inlet of air duct when installing and using facing to automobile fan, make generator when the distance exhaust pipe of engine is very near, thermal insulation and thermal diffusivity are better, the wind that can produce automobile fan effectively is directed in the air duct, thereby has effectively controlled the generator-temperature detection rising, has prolonged the useful life of generator.
