Vidro transparente perfurado para recuperacao do calor e aquecimento de ar utilizando energia solar

摘要

A heat collector comprises a transparent glazing (12) exposed to the ambient. The transparent glazing (12) is spaced from a back surface to define a plenum (16) therewith. A plurality of perforations is defined through the transparent glazing (12) for allowing outside air to flow through the transparent glazing (12) into the plenum (16) and substantially maintain the transparent glazing (12) at the ambient temperature, thereby providing for higher thermal efficiency.
