FIELD: flat electric heaters of emitting type, in particular, film electric heaters, used as a basis for creating radiation heating systems of industrial, social, cultural and inhabited rooms, and also in systems for heating young animals and birds. ^ SUBSTANCE: film electric heater contains meander-shaped thin resistive heating and emitting element made of foil in form of continuous ribbon of precision current-conductive material, positioned between two flexible thermo-resistant electro-isolating films and provided with contacts for connection to electric network. The electric heater is provided with emitting element in form of aluminum foil, mounted between external electro-isolation film and resistive heating and emitting element, and separated from resistive heating and emitting element by electro-isolating film, no more than 30 micrometers thick. The distance between adjacent edges of parallel stripes of resistive element equals 20-100 millimeters. ^ EFFECT: reduced flow of precision material and increased reliability due to reduction of total length of current-conductive section of heater. ^ 2 cl, 1 dwg |
