Dissipator integrated into a compact solar collector

Compact solar collector (1) comprising a containment structure (6) with at least a face exposed to the solar radiation, said containment structure (6) comprising a central housing recess (7) and an outer frame (8) that encloses and laterally envelops said central housing recess (7), inside said central recess (7) being arranged a primary storage conduit (3, 15) for the storage and the circulation of a primary heat transfer fluid, exposed to the solar radiation, a secondary storage conduit (5) for the circulation and storage of a secondary fluid, and an heat exchange area between said primary (3, 15) and secondary (5) conduits for the heat exchange between the primary heat transfer fluid and the secondary fluid,

• said solar collector (1) being characterized in comprising a plurality of vacuum sealed collector tubes (2) arranged within said central housing recess (7), wherein each vacuum sealed tube (2) provides a portion (3) of said primary conduit (3, 15) which envelops a respective portion (5) of said secondary conduit (5) in heat exchange between each other,
• in that in at least a portion of said outer frame (8) of the containment structure (6) is obtained at least a dissipation conduit (9) in fluid communication with said primary conduit (3, 15) for the circulation of said primary heat transfer fluid in order to dissipate the surplus heat outwardly with respect to said solar collector (1), and
• in further providing a circulator (12) in fluid communication between the primary conduit (3, 15) and the at least dissipation conduit (9), said circulator (12) being apt to set in motion the primary heat transfer fluid when the temperature of the heat transfer fluid exceeds a first pre-set value (T1), in order to allow the primary heat transfer fluid to flow and pass through the at least a dissipation conduit (9) at a higher speed in order to reduce the temperature of the primary heat transfer fluid in order to be re-introduced subsequently in the primary conduit (3, 15).
