When the coil body 6 is used in a low-temperature environment, as the insulating temperature regulating plate 9 heats up under electric drive, the coil body 6 is maintained to be stably installed.

As the airflow flows, the temperature is convenient to be reduced, thereby increasing the overall practicality.
