When the temperature gradually reaches the set temperature, the cooling fan is turned on, the heating device continues to operate, and small current is still used for heating, so that the temperature control system reaches heat balance.
When the treatment is finished (that is, the magnetron stops working), the heat dissipating device and the heating device continue to operate, at the moment, the relay 5 is opened, and the heating device is switched to the minimum current working, so that the temperature around the magnetron is kept within plus or minus 2 degrees of the temperature set value, and the magnetron is protected.
