Abstract

The invention discloses a composite heat dissipation structure of a vehicle generator. The composite heat dissipation structure comprises a machine shell, and a generator rotor and a generator statorarranged in the machine shell, and further comprises a fan, a cooling water channel, an electric control water pump, a temperature sensor and a controller; the fan is arranged at the end of the generator rotor and synchronously rotates along with the generator rotor; the cooling water channel is arranged in the outer surface of the machine shell, and the electric control water pump is arranged onthe machine shell and is connected with the cooling water channel; the temperature sensor is installed on the surface of the generator stator; the controller is installed on the machine shell and electrically connected with the electric control water pump and the temperature sensor; the temperature sensor is used for collecting temperature signals in the machine shell in real time and sending thetemperature signals to the controller; and the controller receives the temperature signals sent by the temperature sensor to control the electric control water pump to be opened and closed. The composite heat dissipation structure has the advantages of being high in efficiency, controllable, remarkable in cooling effect and strong in universality.

Description

technical field [0001] The invention relates to the technical field of generators, in particular to a composite heat dissipation structure of a vehicle generator. Background technique [0002] With the development of society, the sales of automobiles increase sharply every year, and people's requirements for the comfort and entertainment of automobiles are also getting higher and higher, and more electronic devices will inevitably be added. As the only power supply in the car, the automotive alternator plays an increasingly critical and irreplaceable role in the stable operation of the automotive power supply system. Therefore, improving the reliability of the generator, a key component of the automobile power supply system, is not only the requirement of market development, but also one of the main ways to improve the quality of automobiles. At present, there are mainly two ways to increase the power of the generator: one is to increase the size of the engine, and the othe...
