METHOD OF OPTIMAL LOCAL INFRARED HEATING Russian patent published in 2005 - IPC

FIELD: methods of central and local heating; production of infrared heaters.

SUBSTANCE: the invention is dealt with the area of heating and may be used for local heating. The method includes a source of an infrared heating using a wavelength from 0.5 up to 7 microns, placed in a reflector. At a stationary height of a heater suspension they determine the heat flows along a local surface of heating: - a heat flow from a source of the IR-heating, - a heat flow from an infra-red heater, - a heat flow from a reflector as a difference between the heat flow of the infra-red heater and the heat flow from the source of the IR-heating depending on the height of(a face) an effective surface of a reflector, they determine the a maximum of a heat flow of a reflector depending on the corresponding to it height of (a face) an effective irradiated surface of the reflector, determine an optimal height of (a face) the reflector corresponding to a maximum of a heat flow. At that at an optimal height of a face of a reflector they determine dependence of a heat flow of a reflector on a change of an angle between a perpendicular to an irradiated surface and a height of (face) a lateral surface of a reflector at the thermal insulation of its external surface, for example, by a material with coefficient of thermal conductivity of 0.05 - 0.15 W/m·K with a degree of blackness of full normal radiation of 0.02 - 0.3, and the optimal value of an angle for a reflector choose corresponding to a maximum of a heat flow of IR-radiation. The technical result of the invention is assurance of a level of optimal intensity in the field of a local heating provided, that the necessary height of a suspension of the source of irradiation and the uniform heating of the surface will be observed.

EFFECT: the invention ensures the optimal level of intensity of a local heating provided, that the necessary height of a suspension of the source of irradiation and the uniform heating of the surface will be observed.
