Electric heater element whose conductor is fastened to the support by gripping

摘要

The invention relates to an electric device for heating the air in contact with the heater element. It consists of a thin support 1 and a heater conductor 1 fixed to the edges of the support by shaping to form clips 4 ensuring effective gripping, through its thickness and width. This arrangement can be supplemented with collared 6 V-shaped notches 5 and perforations 7 under the clips, with the purpose of completing the immobilising of the conductor on the support. This arrangement can change by modifying the shape of the pins 3, site of the heat exchange, and by varying the pitch of the clasps 8 for the purpose of rendering the heat exchange uniform. Such heater elements can be designed with several independent nested conductors. The device according to the invention is intended for equipping convectors or ovens. <IMAGE>
