Double cooling for turbo motors

Abstract

The invention provides a dual cooling apparatus of a turbine generator. The dual cooling apparatus comprises a stator used for receiving power supply to generate magnetic force, a rotor which is magnetized and rotated based on the stator, and an impeller mounted on the end part of the rotor and rotated along with the rotor for conveying air, wherein a freezing refrigerant flowing path is formed inthe stator; a refrigerant inlet is formed in the lower part of the freezing refrigerant flowing path by taking the motor as the center, and a refrigerant outlet is formed in the upper part of the freezing refrigerant flowing path; a clamping sleeve is arranged on the exterior of the stator, and the refrigerant flowing path is sealed by the clamping sleeve; the interior of the clamping sleeve is connected with the outer surface of the stator; and the outer surface of the clamping sleeve is covered with an air flowing channel for allowing cooling air to pass through.

Description

technical field [0001] The invention relates to the field of turbine motors, and more specifically, the invention relates to a dual cooling device for turbine motors. Background technique [0002] The motor is rotated by electricity, and it is a machine that generates power by generating rotational force on its shaft. In this type of motor, the direct-connected turbine motor makes the insulating enameled wire wound on the silicon steel plate generate electromagnetic force, so that the rotor equipped with permanent magnets rotates. , in order to support its smooth rotation, a bearing is provided. This motor is used in the field of blower and air or gas compression. [0003] Centrifugal turbo motors are used for turbo blowers or turbo compressors. This high-speed turbo motor uses an electrical AC conversion device for high-speed rotation of the rotor, so it generates electrical heat, which shortens the service life and damages other components. [0004] In order to cool the g...

Problems solved by technology

[0012] The limitation of this structure is that the air introduced from the outside absorbs the heat of the stator and continues to cool the bearing part on the motor side after raising the temperature, absorbing the heat energy of the bearing part, and the heated air continues to pass between the rotor and the stator to absorb the heat between the rotor and the nail. The air friction heat is discharged from the bearings at both ends, so that the heated air cooling motor and the bearing on the other side will cause a relatively serious thermal deviation as the motor
