Stepped air channel, perforated fins improve passive cooling in PVT
Researchers from Saudi Arabia and Algeria proposed a novel passive cooling system for PV–thermal (PVT) systems that combines a stepped air channel with perforated fins behind a solar panel.
Summary
Researchers from Saudi Arabia and Algeria proposed a novel passive cooling system for PV–thermal (PVT) systems that combines a stepped air channel with perforated fins behind a solar panel. The staircase-shaped air channel is intended to disrupt the insulating air layer that develops along a heated surface. In contrast, the perforated V-shaped fins are intended to increase the heat-transfer area and promote air mixing.
