RÉSUMÉ

The rate of heat transfer and friction factor of heat pipe arrays with transverse spacings between 44 and 52 mm was numerically and experimentally investigated. A total of 19 wickless copper heat pipes with water as the working fluid were used in this study. A forced-convection to natural-convection setup was used on the heat pipe evaporator to condenser cycle. The numerical simulation showed that the rate of heat transfer increases in line with a transverse spacing increase until it reaches its optimum spacing. A reduction in flow movement (mechanical power) is required for larger transverse spacings due to the lower flow resistance caused by the heat pipes. The results from the study show that the heat flux can improve by up to 14% by optimizing the transverse spacing. The heat pipe optimum transverse spacing was determined in this study at a spacing to diameter ratio of 3.1.
