Design and performance study of the heat exchanger of a fin-based thermoelectric generator via numerical simulations
Climate change is a latent concern nowadays, so the
ONU proposed to adopt new alternatives for obtaining energy
through clean and renewable energies; that is why the TEG
(Thermoelectric Generator) have been used in different industries
and vehicles as they are a system that recovers and uses the waste
heat from automobile exhaust gases for waste heat recovery;
therefore, it is a method that allows improving energy efficiency.
The present study aims to design and study the performance of the
heat exchanger of a fin-based thermoelectric generator via
numerical simulations. In this way, the geometry was performed
using SolidWorks software. In addition, the meshing and
boundary conditions were established in ANSYS Fluent to obtain
the initial temperature distributions. Additionally, these initial
temperature distributions serve as boundary conditions for
ANSYS Thermal-Electric to obtain the semiconductor's final
temperature distributions, voltage distributions, and electric
current distributions. It was obtained as a result that the
semiconductor's temperature distributions reached a voltage of 80
mV in 1 second of heat transfer. Also, the droplets fin-base TEG
had an average temperature of 36.85 °C on the cold side and 163.3
°C on the hot side. Finally, it was concluded that the
semiconductor’s final temperature distributions of the hot and
cold side for the droplets fin-base TEG presented higher
uniformity than the parallel plate fin-base TEG
