Abstract

The boundary wall of an air/sand heat exchanger is designed as a porous hollow block wall. Said wall comprises channels (15) which are delimited by channel walls (16). Said channel walls (16) allow the compressed hot air (14) to pass through. Due to the hollow spaces formed by the channels (15), the boundary wall has a low air resistance. The channels (15) may extend in the plane of the boundary wall or at a right angle or any other angle thereto.
