Data on heat rejection alternatives for thermoelectric generator efficient power generation with convection shape pipe material designs

Abstract

The data presented in this experiment, three model convection-shaped pipe materials were designed as an effective cooling alternative for thermoelectric power generation by designing and experimentally modeling the thermoelectric power generator system, which controls the heat transfer of hot side thermoelectric at temperatures of 150 °C, 200 °C, and 250 °C by supplying power through (alternating current: A.C.) transformers to heater coil plate. The cold side fitted to finned heat exchanger is used in combination with an air-cooling system. The purpose of obtaining electrical energy, the experiment, when comparing the three datasets into, showed that the pattern from the use of cylinder pipe materials is the design that provides the highest output power at 15.3W and maximum efficiency of 5.86% at a temperature difference of 186 °C compared to the use of square pipe materials and triangular prism pipe materials with 1.12% and 2.98% lower efficiency, respectively. The temperature control on the hot side is equally constant. The choice of convection cylinder pipe material for cooling fin heat exchanger provides the highest efficiency for thermoelectric power generation.
