Heat insulation and dissipation device for motor

Abstract

The invention discloses a heat-insulating and heat-dissipating device for a motor, which includes a heat-dissipating mechanism arranged outside the motor and a heat-insulating mechanism wrapped outside the heat-dissipating mechanism. It improves the heat dissipation effect of the motor, prevents the motor from overheating, avoids the problem of motor failure due to heat accumulation during work, ensures the normal operation of the motor, and prolongs the service life of the motor. While ensuring a good heat dissipation effect, the heat insulation mechanism can isolate the external heat from invading the motor, which can ensure the normal use of the motor in a high-temperature (about 180°C) sterilization environment, expand the application range of the motor, and improve the medical quality. The automation rate of equipment reduces manual intervention. In addition, the heat insulation and heat dissipation device is arranged outside the motor, without special custom design for the motor, and can be applied to various motor equipment, reducing the use 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
