Experimental Investigation of the Effect of Still Water Cooling on Electricity Generation at Thermoelectric Generator by Solar Energy Heat Pipe

In this study, the effect of still water cooling on electricity generation in a thermoelectric generator heated by solar energy heat pipe is experimentally investigated. For this purpose, a heat pipe with ethyl alcohol as the working fluid has been manufactured. A cooler is used for cooling the thermoelectric generator filled with water. In order to increase the efficiency of the cooler, the system is placed in still water. The highest open-circuit voltage value is 0.44 V for the experiments in which the cooler is used alone and 0.47 V in the experiments made in still water.required
