Özet

A simple experimental framework was developed and supported with computational fluid dynamics to predict the cooling capacity of generic Peltier modules operated under constant voltage. Three modes of heat rejection on the hot face were characterized to obtain the overall heat transfer coefficient multiplied by the effective cooling area (UAf), and the dependence on measuring the hot face temperature was subsequently removed. The approach is demonstrated by constructing cooling curves akin to that of a refrigerant-based chiller, where cooling capacity is plotted as a function of cold-face temperature at a given ambient temperature.
