Description

Efficient cooling device for air-water mixing of motor
Technical Field
The patent of the utility model relates to a motor cooling field.
Background
The cooling of the motor generally adopts air cooling or water cooling, the heating of the stator coil of the air cooling motor is generally taken away through medium air, the heating of the stator coil of the water cooling motor is generally taken away through medium water, and the heat productivity of the rotor cannot be taken away through the circulation of the air because the air gap between the stator and the rotor of the motor is very small and the air cannot circulate; the water channel of the water-cooled motor is arranged on the motor stator shell and is far away from the rotor, so that the heat productivity of the rotor cannot be taken away; the problem of heating of the rotors of traditional air-cooled and water-cooled motors is not a better solution at present.
Disclosure of Invention
To the not enough of above-mentioned existence problem, the utility model aims at: adopt a wind-water cooling hybrid mode to give the motor heat dissipation, take away the calorific capacity of motor stator coil and rotor simultaneously, realize the high-efficient cooling of motor stator coil and rotor.
The utility model discloses a technical scheme, by the water-cooling casing, have winding stator core, rotor, end cover, fan to constitute. The water cooling shell is provided with a section of water sump in the middle, the water cooling shell is provided with an air inlet and an air outlet at two ends of the water sump, the stator slot with the winding stator core is internally designed with a ventilation slot, the winding stator core is fixed at the position of the water sump of the water cooling shell, the fan is fixed at the air inlet of the water cooling shell, the rotor is positioned in the middle of the winding stator core and is supported by end covers at two ends, and the end covers at two ends are respectively fixed with the water cooling shell; circulating water in the water bin on the water-cooling shell takes away heat productivity of the winding stator core, the fan is forced to enter air from the air inlet, and the heat productivity of the rotor is taken away from the air outlet through the ventilation groove in the stator groove of the winding stator core, so that the air-water mixing efficient cooling of the motor is realized.
The utility model discloses simple structure, the cooling radiating efficiency is high, effectively solves the motor small, and the high difficult problem that arouses of loss density's inside temperature rise is too high.
Drawings
The invention is further explained below with reference to the drawings:
fig. 1 is a front view of the present invention:
in the figure: 1-water-cooled shell 2-stator core with winding 3-rotor 4-end cover 5-fan.
The specific implementation mode is as follows:
embodiments of the present invention will be described below with reference to the accompanying drawings; in the embodiment shown in fig. 1, the air-water mixing efficient cooling device for the motor consists of a water-cooled shell 1, a stator core 2 with windings, a rotor 3, an end cover 4 and a fan 5; a section of water sump is arranged in the middle of the water cooling shell 1, an air inlet and an air outlet are respectively arranged on the water cooling shell at two ends of the water sump, a ventilation groove is designed in a stator groove of the stator core 2 with the winding, the stator core 2 with the winding is fixed at the position of the water cooling shell 1 with the water sump, a fan 5 is fixed at the air inlet of the water cooling shell 1, a rotor 3 is arranged in the middle of the stator core 2 with the winding and is supported by end covers 4 at two ends, and the end covers 4 at two ends are respectively fixed with the water cooling shell 1; circulating water in the water feeding bin of the water cooling shell 1 takes away heat productivity of the winding stator core 2, the fan 5 is forced to enter air from the air inlet, and the heat productivity of the rotor 3 is taken away from the air outlet through the ventilation groove in the stator groove of the winding stator core 2, so that air and water mixing and efficient cooling of the motor are realized.
The utility model discloses simple structure, the cooling radiating efficiency is high, effectively solves the motor small, and the high difficult problem that arouses of loss density's inside temperature rise is too high.
