Multi-objective optimization to enhance the performance of thermo-electric generator combined with heat pipe-heat sink under forced convection

The performance of Thermo-Electric Generator (TEG) is negatively affected by heat sink lack of design. The heat pipe heat sink (HP-HS) has the best performance compared to other conventional cooling systems which uses TEG. In medium temperature range below 300 °C, HP-HS is the most appropriate heat...
