Abstract
In this study, exergy loss for different plate surface angles in the plate heat exchangers was investigated experimentally. Chevron angles of plate heat exchangers are 30o and 60o. Firstly, experimental setup used plate heat exchanger was constructed. Performance analyses for different plate surface angles in plate heat exchangers were investigated. The heat transfer rate and exergy loss are determined. Results of the study show that heat transfer rate and exergy loss for 60o is higher than 30o. The maximum heat transfer rate for 60o is about 35 kW. The minimum heat transfer rate for 60o is about 23 kW. The maximum exergy loss value for 60o is about 33 kW. The minimum exergy loss value for 60o is about 13 kW. The results of the study are given graphically.

Abstract
Bu çalışmada, plakalı ısı eşanjörlerinde farklı plaka yüzey açıları için ekserji kaybı analizi deneysel olarak incelenmiştir. Plakalı ısı eşanjörlerinin plaka yüzey açıları 30o ve 60o'dir. Çalışma için ilk olarak, plakalı ısı eşanjörü kullanılan deney düzeneği oluşturulmuştur. Plakalı ısı eşanjörlerinde farklı plaka yüzey açıları için performans analizleri yapılmıştır. Isı transfer miktarı ve ekserji kaybı belirlenmiştir. Çalışmanın sonuçları, 60o plaka yüzey açısına sahip plakalı ısı eşanjöründeki ısı transfer miktarının ve ekserji kaybının 30o plaka yüzey açısına sahip plakalı ısı eşanjöründekinden daha yüksek olduğunu göstermektedir. 60o plaka yüzey açısına sahip plakalı ısı eşanjörü için maksimum ısı transfer miktarı yaklaşık 35 kW'dır. 60o plaka yüzey açısına sahip plakalı ısı eşanjörü için minimum ısı transfer oranı yaklaşık 23 kW'dır. 60o plaka yüzey açısına sahip plakalı ısı eşanjörü için maksimum ekserji kaybı değeri yaklaşık 33 kW'dır. 60o plaka yüzey açısına sahip plakalı ısı eşanjöründeki için minimum ekserji kaybı değeri yaklaşık 13 kW'dır. Çalışmadan elde edilen sonuçlar grafiksel olarak verilmiştir.
