Electric surface heater - has carrier with central trough for placing heating element which can be filled with electrically insulating heat conducting material

摘要

The electric surface heater (10) has a resistance element (12) which is contacted with external electrical current supply conections. One side of the carrier (24) at the base of the central trough (14) and the opposing second side of the carrier are formed by the surface (26) of the filling material (22). The carrier (24) for the heating element (12) consists of a pourable, capable of being hardened, electrically insulating and good heating conducting material (60), in which the heating element (12) is cast. The layer thickness of the filling material (22) or the thickness of the carrier matches the heat storage duration of the surface heater (10). USE/ADVANTAGE - Electrical surface heater. Carrier for electric resistance heating element is very simply and time saving produced. Desired output obtained with matched carrier.
