FLEXIBLE ELECTRIC HEATER Russian patent published in 2003 - IPC

FIELD: electrical engineering. SUBSTANCE: proposed uninflammable electric heater that can be used for drying wood, heating liquids, manufacturing heated vests, covers, blankets, and the like has two layers of insulating base with current-conducting resistive layer in-between, current conductors electrically connected to this layer and disposed on its both ends; novelty is that each conductor is formed by pair of metal strips, one superposed on other, that resistive layer is made of carbon harnesses or threads whose ends are fitted between pair of metal strips on two sides, pair of metal strips is joined by spot welding and insulating base layers are joined to resistive layer by means of adhesive. EFFECT: enhanced reliability and facilitated manufacture of electric heater. 6 cl, 1 dwg
