摘要： The aim of the invention is the application of simple production methods for electrical resistance heating elements with a honeycomb body and use total capacity with regard to the specific electrical power per volume unit. Said aim is achieved for an electrical resistance heating element with a honeycomb body of resistance material with positive temperature coefficients for the resistance (PTC resistance), in which the channels, for throughflow of a medium for heating, comprise metallised walls and are electrically alternately contacted after the fashion of a chess-board on the front faces of the honeycomb body by means of a front face metallisation, whereby an insulation region (1) is alternately let into the metallisation (3) on the walls of the channels running from the front faces, whilst the front face metallisation (2) completely covers the front faces. Possible fields of application for the above (without limitation thereto) are particularly additional heaters and windscreen heaters in motor vehicles or small, self-regulating and rapidly-responding room space heaters.

摘要： A method applies layers to channels of a resistance heating element, where the channels are arranged in a honeycomb structure and receive a medium to be heated. Adjacent layers communicate with electrically conducting end-face metallizations of the resistance heating element and have, at an opposite end, an insulation region in relation to another respective end-face metallization. To apply the layers, a miniature lance is immersed into the channel to be coated. The miniature lance is hollow, closed at a lower end, has an upper end communicating with a reservoir of metal paste, and includes outlets in a lower region that are directed to inner walls. Metal paste is uniformly applied to the inner walls of the channel by pressure while simultaneously moving the miniature lance. The miniature lance is inserted into an adjacent channel for coating inner walls of the adjacent channel from the other end-face metallization side.
