Wie aus der Fig. 1 zu ersehen ist, ist ein erfindungsgemäßer Heizkörper 1 aus zwei
identischen Halbschalen 2 aufgebaut, die mit Einprägungen versehen sind, die eine
Wasserführung 3 definieren. Die beiden Halbschalen 2 sind zu beiden Seiten der
Einprägungen, bzw. der Wasserführung 3 z.B. über Löt- 4 Klebeverbindungen oder
Prägungen miteinander verbunden.As can be seen from FIG. 1, a radiator 1 according to the invention is composed of two
identical half-
An der Außenseite des Heizkörpers 1 sind unter Zwischenlage einer elektrisch isolierenden
Schicht 5 elektrische Heizelemente 6 angebracht. Dabei stehen die Heizelemente 6 in gut
