Abstract

A folded plate is as a corrugated plate in its two directions. The effect of folded plates on the heat transfer is studied experimentally. The temperature distribution of folded plate was compared with flat plate The Arrangement of plates was changed as the following (Flat-Flat), (Flat-Folded), (Folded-Folded). Results are carried out by changing the gap between the two folded plates (1, 4 and 6 cm ) with different air flow rates from 5.4 to 11.2 liter/s, Reynolds number changes from (3969 – 11384) and different heat flux in ranges of 3.8 to10 kW/m2 based on projective area. The re-sults show that, the folded plate produces faster uniform temperatures distributions on plate surface. By increasing heat flux, the average temperature increases. Also, it is found that as the gap between plates increase, the average plate surface temperature also increases. The obvious effect of the folded plate on temperatures is due to the more turbulence effect on the air flow generated by the geometric of the folded plate. The folded plates are a suitable shape to improve the thermal performance of heat transfer as compared to Flat plate.
