Electrical heating element for fluid media and method for producing same

An electrical heating element for fluid media, more particularly for hot air appliances, comprising a support member of insulating material and at least two heating conductors which are made of resistance wire and which surround the support member, the heating conductors being wound as helical coils and supported on supporting edges of the support member, the coils being wound with radial spacing from one another. The heating conductors may comprise an outer coil consisting of a resistance wire of high specific power consumption and an inner coil consisting of a resistance wire of low specific power consumption. The support member may comprise a tubular body with ribs projecting radially at the periphery, said ribs forming the supporting edges. The outer ribs may be U-shaped extending from end to end of the tubular body and forming passages through which the turns of the inner coil pass. The ribs preferably comprise mica strips; various mounting means for such strips are described.
