METHOD OF MAKING FILM-TYPE ELECTRIC HEATER (VERSIONS) Russian patent published in 2010 - IPC H05B3/16 

FIELD: physics.

SUBSTANCE: in accordance with the first version, the method involves depositing a 10 nm to 10 mcm thick current-conducting coating onto a substrate in form of at least one strip with a different shape and further connection of leads and deposition of a protective coating made from dielectric material. In the second version, the method involves deposition of a 10 nm to 10 mcm thick current-conducting coating on a substrate and further cutting off a resistive radiating element of different configuration, located between two layers of dielectric material and subsequent connection of leads and all layers. In the third version, the method involves making a resistive radiating element by depositing a 10 nm to 10 mcm thick current-conducting onto a dielectric substrate in form a strip, where along the edges of the strip, a field is left without current-conducting coating, making slotted openings of the same shape which project beyond the boundary of the deposited strip, depositing a power bus with leads on the field of the band without coating, connection of layers of dielectric materials on both sides. Deposition of a current-conducting coating (resistive radiating element) with thickness between 10 nm and 10 mcm onto a dielectric substrate reduces the cost price of the film-type electric heater. By varying the length and width of the strip of the resistive radiating element, different radiation power of the film-type electric heater can be obtained, thereby increasing efficiency without changing its size.

EFFECT: design of cheap and less labour intense methods of making a film-type electric heater with corresponding technology of making a resistive radiating element, for which the price of expensive current-conducting material is lowered.
