Solar air heaters are used as energy-saving devices in moderate to hot air because of the low temperature difference between the lower surface and the outlet assembly. The temperature difference was occurred between the lower plate and the upper plate. There are several ways to improve air heaters. Solar panels use synthetic rigidity to improve heat transfer rate. To obtain a high convective heat transfer coefficient, flow turbulence in the heat transfer zone is required. But the power to create chaos did come from fans or fans, and too much requires more power. Test assemblies are made of different materials, flat glass, wood, collectors, inlets, and outlets. The accumulators produce hot air with the help of the sun. Normally, the air flows through the inlet, and eventually, the hot air flows out through the hole. Measure the maximum temperature of the hot air (°C) during the measurement.
