Abstract (en)
[origin: EP0282085A1] The heating element for heating fluids contains as a heat exchanger a metal member composed or a number of individual members (1, 2). The individual members have many penetration openings (3) which on the inlet side are conically widened. Between the individual members, PTC elements 11 are arranged, which carry out the heating. These PTC elements (11) are encapsulated in a plastic layer (14), from which the webs (4, 6) are formed, which carry out the mechanical fixing of the individual members (1, 2). On installation of the heating element into a pipe, the annular covering (7) acts as thermal and electrical insulation, as the individual members (1, 2) also function as current supply for the PTC elements (11). <IMAGE>
