The working process of a mica heater in a fan involves generating heat through resistance and circulating that heat using the fan's airflow. Here's how it works:
Electrical Current Flow: When the fan heater is turned on, an electrical current flows through the heating element, typically made from a coiled resistance wire, such as nichrome, which is supported by mica sheets.
Heat Generation: As the current passes through the nichrome wire, the high resistance causes the wire to heat up. The mica sheets insulate the wire and provide a stable structure for the heating element, ensuring safety and efficient heat conduction.
Air Circulation: The fan within the heater starts rotating and blows air over the hot mica-supported heating element. As air passes over the heated wires, it absorbs the heat.
Heat Distribution: The heated air is then blown out of the fan heater's vent or grill, providing warm air to the surrounding space. The fan ensures that the heat is distributed evenly and quickly.
Temperature Regulation: Most fan heaters with mica elements come with thermostats or thermal cut-off switches that regulate the temperature, preventing overheating. The mica sheet in the heater helps maintain thermal stability, ensuring the heater operates efficiently and safely over extended periods.
This design makes mica heaters in fans highly effective, offering fast and even heat distribution with thermal insulation for enhanced safety.
