Embodiment

[0015] Example, gravity cycle evaporative cooling motor.

[0016] Such as figure 1 and figure 2 As shown, the gravity cycle evaporative cooling motor includes a stator 1, a rotor 2, and a casing 3, and also includes a stator evaporator 4, a vapor-liquid separation chamber 5, a condenser 6, a rotor metal tube evaporator 7, and a rotor heat exchanger 8 , Lubricating oil heat exchanger 9. The stator 1, the rotor 2, and the casing 3 are similar to the general air-cooled motor, but structures such as cooling air ducts are no longer considered. On the outer surface of the stator 1, two stator evaporators 4 are arranged on both sides. The thermally conductive metal plate 41 of the stator evaporator is preferably a copper plate of 2-5 mm, which is closely attached to the stator core through a thermally conductive insulating film; A pressurized fastening steel plate 43 is installed between the root metal tube evaporation chambers 42, and the upper and lower sides of the pressuriz...

Abstract

The invention discloses a gravitational circulation vaporization cooling motor. The gravitational circulation vaporization cooling motor is characterized by comprising an externally cooling stator and a sealed and internally cooling rotor, wherein the heat of the rotor is conducted into a stator vaporization cooling system through a heat exchanger; and a rotor metal tube vaporization chamber in a semi-interference state remains unobstructed space with a condensation chamber thereof, so that the whole rotor can be cooled uniformly.

Description

technical field [0001] The invention relates to a gravity cycle evaporative cooling motor, in particular to a gravity cycle outer evaporative cooling stator and a closed inner cycle evaporative cooling rotor. Background technique [0002] Generators and motors are usually cooled by air or water. They are attracted by the very high cooling efficiency of evaporative cooling technology. Over the years, some people have conducted intermittent research, but the effect of industrialization has not been ideal. On the one hand, it works at 50-60Hz Constrained by the saturation flux and efficiency requirements of power-frequency electromechanical equipment, the thermal power density cannot be very high. At the same time, the evaporative cooling technology of large-volume electromechanical equipment cannot solve the problems of sealing, deformation under pressure and circulation satisfactorily. Wind turbines are installed on high towers in the field, and the power tends to increase. I...
