Abstract

The utility model relates to a water pump-generator, which comprises an annular stator (1), an annular rotor (2) and a water pump. The utility model is characterized in that the annular stator (1) is arranged on a shell (9) of the water pump, the annular rotor (2) is arranged on a rotary wheel (3) of the water pump, the annular stator (1) and the annular rotor (2) are arranged face-to-face, the generator and a water pump mechanical device are coaxially operated and directly driven, and the multiple function of the water pump and the generator can be realized in a whole. The water pump-generator can make the combination of the generator and the water pump machine more reasonable and compact, the structure is simple, and the cost is reduced. Because the stator is directly and fixedly arranged on the shell of the water pump, heat energy which is generated by the stator can be taken away by circulation water of the water pump, and the operating temperature of the generator can be reduced. Consequently, the water cooling type efficient water pump-generator without noise can be formed and has the advantages of low operating temperature, compact structure, simple structure and reasonable structure.

Description

Water pump-generator

(1) technical field

The utility model belongs to a kind of automobile water-based pump-generator multiplexer.

(2) background technique

At present, water pump, generator that automotive field uses are stand-alone configuration, are bringing into play function separately each other.Raising along with development and national economy, progress of science and technology and living standards of the people, performance to automobile has proposed to upgrade higher requirement, still traditional stand-alone configuration water pump and air-cooled generator that Hyundai Motor still uses make the integral arrangement structure of motor rationally compact inadequately; Along with the continuous increase of automobile electrical appliances loads, make that the generator and the 12V power supply system of automobile can not adaption demands now.

(3) summary of the invention

It is a kind of with water pump and becoming one of generator that the purpose of this utility model is to provide, and makes more advantages of simple compactness of modern water pump and electric generator structure, realizes high-power water-cooled water pump-generator.

For achieving the above object, the technological scheme that the utility model is taked is: this water pump-generator comprises a ring-type shape stator, a ring-type shape rotor and a water pump, it is characterized in that described ring-type shape stator is installed on the described water pump cover, described ring-type shape rotor is installed on the water pump runner, described ring-type shape stator and described ring-type shape rotor cover opposite are provided with, generator and the coaxial running of mechanical water pump device directly drive, and consubstantiality is realized water pump and generating multiplex function.

Above-mentioned water pump-generator water collecting pump and generator are one, the parts such as shell, end cap, bearing, rotating shaft and wind-cooling heat dissipating device of generator have been cancelled, make generator and the more reasonable compactness of combining of mechanical water pump, simplify the structure, reduced cost, directly be fixedly mounted on the water pump cover because of stator again, the heat that stator produces is taken away by water pump circulating water, greatly reduce the operating temperature of generator like this, a kind of operating temperature is low, the water-cooled noise free Efficient water pump-generator of simple and reasonable compactness thereby constitute.
