Abstract (en)

[origin: WO2005096672A1] The invention relates to an electric resistance heating element for heating flowing media. The aim of the invention is to provide an assembly for electric resistance heating elements, which can be configured from simple technology and at the same time produces high power densities. This is achieved by an electric fluid heater consisting of a ceramic or polymer composite material with a plurality of channels, through which the medium to be heated flows. Said inventive fluid heater consists of at least one heating element, which is provided with at least one channel and whose opposing external surfaces comprise electrode surfaces, whose action causes a current to flow between said electrode surfaces, in an essentially transverse direction to that of the channels. At least one of the two electrode surfaces of the heating element has a connection surface that is located on the adjoining external surface of the heating element.
