Purpose of the development: The use as heating elements in various instruments, devices, media.

Recommended application field: Heaters for use in aggressive environments, infrared emitters for various applications, heaters for boilers, heaters and heaters for drying machines, heaters, household appliances, heaters technological devices (furnaces, dies).

Technical characteristic: The maximum heat flux from the surface: when operating at conditions of natural heat - 15-75 W / sm.kv.; when working in heavy tepoobmena: while blowing air at a rate of 10-25 m / sec - 20-85 W / sm.kv.; when working in the liquid flow - 30-90 W / sm.kv.; when operating in the thermal insulation (furnace) -10-50 W / sm.kv..

Advantages over analogues: Low inertia, large permissible thermal load, high efficiency. The principal difference between the new heaters - no metal components.

The development stage readiness: Introduced in production

Description of the development:
()
Ceramic "spiral" is located inside the ceramic "shell" ceramic material "spiral" has a melting point of about 3000 degrees C and is heated electric current supplied through contacts, to a temperature of 1400-2300 degrees C. Hot spiral radiates heat flux density of 125 W / sm.kv.. Ceramic electrical insulation and acts as a shell and a heat transfer medium with a thermal conductivity of 40-60 W / m K. The surface of the ceramic "shell" created by the heat flux density up to 75 W / sm.kv. under conditions of intense heat. Ceramic "spiral" has inductionless nature of resistance and all-ceramic heater with a ceramic "spiral" does not require additional equipment to maintain a constant operating temperature zones heat the material has a positive temperature coefficient of resistance with a maximum temperature 700-1200 degrees C. The ceramic shell provides high parameters device operation in the entire range of operating temperatures. It has a unique combination of mechanical, thermal, electrical properties and high corrosion resistance. The ceramic shell can work in direct contact with food. The innovation elements can be used as high-performance ballast resistors 0,3-3000 Ohm for power and electrical engineering as ceramic thermocouples with linear characteristic in the range of 200-2000 degrees C and a sensitivity of 60 mV / degree as an external heating units sintered sample laboratory microwave ovens at the temperature 1000-2000 degrees C, both dense and porous ceramic products Si3N4, ALN, BN, SiC and other oxygen-free compounds. It is widely used elements in scientific experiments.
