ELECTRIC CONVECTOR Russian patent published in 1999 - IPC

FIELD: heaters for homes in winter. SUBSTANCE: device has device has rectangular housing 1 with intake hole 2 and exit hole 3, rests 4, vertical members which are arranged in housing in parallel and are designed as flattener 5, which carries insulation substrate and flat heater 6, and current supply assembly 7. External surface of flat heater 6 of each flattener 5 is covered with heat-resistant insulator and layer 8, which is made from material which reflects at least 90-95% of radiation. Ratio of flatteners height H to their width B conforms to condition 0,5<H/B<1,5; ratio of width B to distance between flatteners t is in range of 5≤B/t≤18, ratio of flattener's surface area F_B to heater's surface area f_H is in range of 5<F_B/f_H<15,. Ratio of height of flattener H to distance h from floor to lower exit section is in range of 3,5<H/h<35. EFFECT: increased service life, increased reliability and decreased environment pollution. 2 dwg
