PERFORATED TRANSPARENT GLAZING FOR HEAT REMOVAL AND AIR HEATING DUE TO SOLAR RADIATION Russian patent published in 2013 - IPC F24J2/50 F24J2/04 

FIELD: heating.

SUBSTANCE: thermal collector includes transparent glazing (12) that is in contact with environment. Transparent glazing (12) is located at some distance from rear surface so that chamber (16) is formed between them. A lot of through perforated holes are made in transparent glazing (12); they allow the ambient air flow through glazing (12) to chamber (16) and maintain the temperature of transparent glazing (12) at the ambient temperature level; in addition, those holes are distributed along some part of transparent glazing surface, and chamber has an outlet; glazing also includes air movement device designed for suction of heated air from the chamber through the outlet. Air heating device includes transparent perforated surface that is transparent for solar radiation; solar radiation absorbing surface that is located behind transparent perforated surface for solar radiation absorption; and air gap formed between transparent perforated surface and radiation absorbing surface; besides, the air flowing in the gap absorbs the heat from the radiation absorbing surface, while fresh ambient air flowing through the holes made in transparent perforated surface provides minimum temperature gradient in cross section of that section.

EFFECT: higher thermal efficiency.
