LONG-SIZED FLEXIBLE ELECTRIC HEATER AND METHOD OF ITS MANUFACTURE Russian patent published in 1997 - IPC

FIELD: flexible heating elements with carbon-fibrous resistor, can be used independently for heating of greenhouses, living spaces and production areas, as well as components of other appliances such as air heaters. SUBSTANCE: the electric heater is a resistor in the form of a bundle of carbon fibres, first insulating layer of heat-conducting material in the form of a winding or braid, and the second layer of polymeric material, current leads which have three pairs of lugs each: one pair fixes the end of the resistive element freed of electric insulation between the terminal and section of the first insulating layer, the second pair of lugs crimps the second insulating layer, the third pair of lugs fixes the insulating tube. EFFECT: enhanced specific surface heat release and enhanced reliability of electric heater, simplified and enhanced adaptability of its manufacture. 2 cl, 3 dwg
