Improvement of a solar collector panel

摘要

The invention relates to a solar collector panel (2) configured for collecting thermal energy by heating of air, said solar collector comprising an axial fan (1), which fan (1) comprises an electrically driven impeller (3), wherein the fan (1) during operation is arranged to transport air heated within a volume (12) of the collector panel (2), away from the collector panel (2), through an air outlet (9) extending to the exterior of the solar collector panel (2), and wherein said fan (1) comprises one or more flow straightening members (6) arranged at the suction side (7) of the fan (1) acting on the flow of air through the fan (1) during operation of the fan (I).
