Abstract:
Device for transferring heat between a panel to be heated by solar radiation and a wall, the device comprising:an insulating plate mounted parallel between the panel and the wall to define an external closed space between the panel and the insulating plate, and an internal closed space between the insulating plate and the wall; a partition mounted in each of the external space and the internal space to define therein at least one U-shaped path with two branches for air circulation, one branch on each side of the partition; an air circulator interposed between the external space and the internal space, wherein said air circulator includes at least two openings provided in the insulating plate, each of which is designed to provide fluid communication between the branches of the external space, and fluid communication between the branches of the internal space; and a first fan positioned in at least one of the at least two openings and operable in the following two states: an open state allowing circulation of air between the external space and the internal space via at least one of the at least two openings to allow heat transfer between the panel and the wall; and a closed state preventing circulation of air between the external space and the internal space to prevent transfer of heat between the panel and the wall.
