碩士 / 國立成功大學 / 航空太空工程學系碩博士班 / 97 / The present study is to extend the work of Jin-Han Liu on heat pipe based solar ventilation device. The main purpose of the study is to discuss the effects of height and number of heat exchanger fins on the ventilation. The approach of study is similar to that used in Liu’s research, which employed simulated solar radiation with heating device. Heat pipes were used to transport the heat from heat absorber to heat exchanger fins and create natural convection ventilation effect.
The test bed has a 0.6m2 heat absorber with preset 600W heating and 8 syphon type heat pipes of 8mm in diameter laid on the absorber to transport the heat. The fins has 3mm thickness, with 3 different heights (5cm, 10cm, and 20cm), and different numbers (15, 30, 45, and 60).
Temperature measurements were conducted on heat pipes, fins, and at the exit of the vented duct with flow velocity measured. The results showed that the vented heat is proportional to the number of fins, and is also proportional to the height of fins. It was found that the best ventilation result in the study lies at 45 fins and 10cm fin height.
