Background

An electric fan, also called fan and fanner, is a household electrical appliance which uses an electric motor to drive fan blades to rotate so as to accelerate the circulation of air, and is mainly used for cooling and relieving summer heat and circulating air. The utility model is widely used in the places such as families, classrooms, offices, shops, hospitals, hotels, etc.

When the electric fan works (assuming that the room has no heat transfer with the outside), the temperature in the room is not reduced, but is increased. The reason for the temperature rise was analyzed: when the electric fan works, because current passes through the coil of the electric fan and the conducting wire has resistance, heat is inevitably generated and released outwards, and the temperature is naturally increased. But why people feel cool. Because a large amount of sweat exists on the body surface of a human body, when the electric fan works, indoor air flows, so that the quick evaporation of the sweat can be promoted, and people can feel cool by combining the fact that evaporation needs to absorb a large amount of heat.
