Heat transfer in a cubical container filled with water and cooled by a Peltier device was investigated experimentally in this study. Hot surface of the Peltier device was cooled by a heat sink. Three temperature sensors were used in each direction in the container. The data measured by temperature sensors are send to an Arduino microprocessor in order to process data and send the results to an LCD screen and a computer to store the measurements. Results show that decrease in temperature inside the container is low in the early stage of cooling and it starts to increase as time progresses as a result of strengthening circulation. Results also show that temperature gets considerably lower values in the lower part of the container than that of the upper part. Results also indicate that temperature difference is low in the direction normal to the cooled surface. Finally, results indicate that heat transfer rate shows a decrease with time as the flow progressively approaches a steady state regime.
