In order to prevent the electric actuator from being in the cold, the temperature difference between day and night is large, and the air humidity is high, the internal cavity of the actuator is used to condense inside the chamber, and the newly installed PTC dehumidification heater is used to control the air in the inner cavity. Heating to prevent condensation, the heater takes a continuous working system.

The PTC dehumidification heater is composed of a PTC ceramic component and an aluminum tube. The PTC heating element has the advantages of small thermal resistance and high heat exchange efficiency, and is an automatic constant temperature and power-saving electric heater, which is characterized by safety performance. Under any application, the surface of the electric heating tube heater will not be reddened, which may cause burns, fires and other safety hazards.

In addition, the structural improvement of the housing of the intelligent electric actuator can be achieved, and the moisture-proof and water-repellent structure modification of the electric actuator housing comprises an electric actuator housing, a heating resistor inside the housing, and a lower part of the housing. The venting hole is characterized in that the shroud is fixed at the exhaust hole at the lower portion of the electric actuator housing. In addition, by adding a shroud at the lower exhaust hole of the electric actuator housing, the water in the lower part of the housing does not flow backward into the housing, but only moisture enters; the incoming moisture can be passed through the original electric heating. Thoroughly eliminated to ensure the drying inside the casing.
