  • Patent number: 4230933
    Abstract: An electric air heating element is designed for positioning in the cylindrical or conical outlet tube of a hair dryer. It consists of a star-shaped coil carrier in the shape of four fins extending radially from a common center line in the axis of the outlet tube towards the tube walls. The fin edges are serrated by adjacent rectangular slots, the slots on each edge penetrating alternately to a shallow and to a greater depth, and a ribbon-shaped resister laid into these slots is helically wound around the coil carrier. In this way successive windings lie in different planes and air turbulence around the heating coil is thereby increased, improving the heat transfer between the resistor windings and the throughflowing air.
