Development Of High Efficiency Long Wavelength Infrared Radiators For Medical Applications

Description

The main task of this development is choice material, investigate its properties and create technology for production of high efficiency infrared sources of thermal energy. The idea to use layered gradient ceramics was developed by V. Petrovsky and gives possibility to solve next problems:

  • Increase the wavelength range up to 7 - 12 μm at the same or higher surface temperature
  • Decrease the power consumption of one heater up to 25 - 30%. Such distribution of energy sufficiently increased physio-therapy efficiency and reduce power consumption above 450W per physiotherapy chamber.
  • Create essentially new system for sterilizing treatment equipment: the two heaters with sizes 100 x 8 x 8 mm3 can radiate 825 Watt for heating the air blast (under pressure 8 atm. the speed is about 20 km/h at the temperature 300°C.)

This heated air blast can obliterate all bacteria and microbes on any surface during parts of second.

Innovative Aspect and Main Advantages

Decrease the power consumption at some thermal efficiency. Follow on the concept of layered composite there are offered the three type of IR radiators:
(i) low temperature IR radiator based on layered structure of composite based on heat source from flexible ribbon heater (Fig.1) and IR radiated surface based on glass ceramic (temperature range before 150°C) (fig.2);
(ii) middle temperature IR radiator based on heat source from flexible ribbon and IR radiated surface based on heater silicon nitride (temperature range 300 - 550°C);
(iii) high temperature all ceramic IR radiator (temperature range 500 - 1100°C) for utilization at condition of intense heat - exchange (Fig.3).

Areas of Application

Energy sawing electrical heating of industrials and living rooms; medical application in area of human physiotherapy; system for sterilizing treatment equipment of rooms or medical equipment.

Stage of Development

(i) Low temperature IR radiator for industrial and living rooms – commercialized;
(ii) Middle temperature IR radiator for of human physiotherapy
(iii) high temperature all ceramic IR radiator for sterilizing treatment - prototype available for testing;
