The invention relates to an electrical heater with a tubular housing and with a heating insert inserted in the housing. The heating insert includes at least one PTC thermistor. Herein, at least one concave indentation is formed in the housing, which is at least punctually in contact with a corresponding concave indentation of the heating insert. Furthermore, the invention relates to a method for manufacturing such an electrical heater.

Electrical heater and method for manufacturing an electrical heater

The invention refers to an electric heater for a clothes dryer, said heater comprising at least one heating wire, a ring shaped support structure carrying the at least one heating wire. The at least one heating wire is a flat wire bent into loops.

Electric heater for a clothes dryer

An electric heater for gaseous media with at least one support plate and at least one helix of corrugated, electric resistance heating wire wound continuously around the support plate and whose turns are held by means of heating wire bend-offs on the longitudinal edges of the support plate is characterized in that the heating wire is positioned in such a way that it only contacts longitudinal narrow sides and/or edges of the longitudinal narrow sides of the support plate, the bending angle being much larger than 40&#xb0;. This significantly reduces the risk of thermal damage to the heating wire, particularly in the vicinity of the plate edges. As a result of the largely naturally stable design of the heating wire, the heater according to the invention requires no spacers between the support plates and is therefore particularly simple and inexpensive to manufacture.
