Heating element for air - has helical heating wires meandering between lateral retainers via central slots

摘要

The heating element, for air, has an insulating T-shaped support (6) inverted and provided with slots (5) spaced along its stem and retainers (9) along the outer ends of the crosspiece's arms. Helical heating wires (4) pass from the retainers on one side via the slots to the retainers on the other side. - Each retainer consists of a metal angle bracket whose one limb is fixed to the support and whose other limb acts as a flat post for the heating wire loops.
