#CMT# #/CMT# The electric heating device has a heating wire (2), which is connected with an electrical energy supply unit. Another heating wire is arranged along the former heating wire and is connected with the former heating wire in an electrically insulating manner. The heating wires are supplied with heat current independent of each other. #CMT#USE : #/CMT# Electric heating device. #CMT#ADVANTAGE : #/CMT# The electric heating device has a heating wire, which is connected with an electrical energy supply unit, where another heating wire is arranged along the former heating wire and is connected with the former heating wire in an electrically insulating manner, and thus ensures to change the thermal output of the electric heating device with simple units. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional view of an electric heating device. 2 : Heating wires 3 : Aluminum foil strip 4 : Insulations. |
