ABSTRACT In the present work an attempt has been made to investigate the performance of a 3 channel 1-1 pass, corrugated plate heat exchanger. The plates had sinusoidal wavy surfaces with corrugation angle of 45 0 . Hot water at different inlet temperature ranging from 40 0 C to 60 0 C was made to flow in the central channel to get cooled by water in the outer channels. For hot and cold fluid, Reynolds number was in the range of 900 < Re > 1300. Performance was measured in parallel and counter flow arrangement. Exergy loss is calculated and it is found that exergy loss is more in parallel flow arrangement than in the counter flow arrangement. Key words: Heat Exchanger, Reynolds number and loss.

INTRODUCTION Heat exchanger is a most important device used to transfer heat from one fluid stream to another. They are widely used in the various engineering applications. Their design requirement is to increase the energy saving and to decrease the cost. The way to improve the global performances of plate heat exchangers is to find efficient heat transfer surfaces which do not induce much pressure loss. Corrugated plate heat exchangers are used to increase the thermal performance and higher compactness. Breaking and destabilizing in the thermal boundary layer are occurred as fluid flowing through the corrugated surfaces. Many researchers have studied on the heat transfer characteristics of the corrugated channels. Experimental and numerical studies were performed by Sunden and S.Trollheden on the heat transfer and pressure drop in the corrugated channels and the smooth tubes. It was found that the heat transfer obtained from the corrugated channel was 3.5 times higher than that from the smooth tube. The pressure drop in the corrugated channel is 5–6 times larger than that from a smooth channel. Fabbri has studied the laminar convective heat transfer in a channel
