Heat insulation and dissipation device for motor

Abstract

The invention discloses a heat insulation and dissipation device for a motor, and the device comprises a heat dissipation mechanism disposed outside the motor, and a heat insulation mechanism wraps the heat dissipation mechanism. The heat dissipation mechanism achieves the conduction of heat generated during the operation of the motor to the outside, thereby achieving the heat dissipation of the motor, preventing the overheating of the motor, avoiding the faults caused by the heat accumulation when the motor works, guaranteeing the normal operation of the motor, and prolonging the service lifeof the motor. The heat insulation mechanism prevents external heat from entering the motor while guaranteeing the good heat dissipation effect, and can guarantee the normal use of the motor in a high-temperature (about 180 DEG C) disinfection environment, thereby enabling the application range of the motor, improving the automation rate of medical equipment, and reducing the artificial intervention. In addition, the device is disposed outside the motor, and there is no need to carry out the special customization of the motor. The device can be used for various types of motor equipment, and reduces the application cost of the motor.

Problems solved by technology

[0004] During the energy conversion process of the motor, the internal loss will be generated at the same time, and the lost energy will eventually be converted into heat energy, which will increase the temperature of each part of the motor. This heat accumulation will cause the reduction of the internal insulation capacity of the motor and limit the motor output, shortening the life of the motor

This is due to the fact that the motor has insulating materials inside. If the temperature is too high, the electrical, mechanical and chemical properties of the insulating materials will be significantly deteriorated, and the motor will be burned in severe cases.

At present, most motors do not have cooling devices, and rely on the casing to cool down naturally. A few motors with cooling devices have poor cooling effects. During the operation of the motor, there are still problems of motor overheating, failure, and short service life, especially in the field of biomedicine. , the motor often needs to work in a high temperature sterilization environment, and the ordinary motor does not have the function of heat insulation and heat dissipation, and cannot withstand high temperatures. Under such extreme conditions, the poor heat dissipation of the motor will have a more important impact on its service life
