Miguel Araiz Vega studied industrial engineering at the Public University of Navarre (UPNA), Spain, and completed his Ph.D. at the same university in 2018. The topic of his thesis was the modelization and development of a thermoelectric generator to harvest waste heat in domestic and industrial processes. He is a member of the Thermal and Fluids Research Group and the Smart Cities Institute of the UPNA. He completed a short research stay at the Royal Melbourne Institute of Technology (RMIT) in Melbourne, Australia in 2018, and he has collaborated in many research projects related to thermoelectric generation and refrigeration, and simulation, design, and optimization of heat exchangers and thermal systems. He has published fourteen manuscripts in peer-reviewed international journals and one book chapter, and he has participated in more than twenty-five international and national conferences.

Thermal energy is present in all aspects of our lives, including when cooking, driving, or turning on the heat or air conditioning. Sometimes this thermal management is not evident, but it is essential for our comfort and lifestyle. In addition, heat transfer is vital in many industrial processes. Thermal energy analysis is a complex task that usually requires different approaches. With five sections, this book provides information on heat transfer problems and using experimental techniques and computational models to analyse them.

The Importance of the Assembly in Thermoelectric Generators

By Miguel Araiz, Leyre Catalan, Oscar Herrero, Gurutze Perez and Antonio Rodriguez

Generally, in the optimization of thermoelectric generators, only the heat exchangers or the thermoelectric modules themselves are taken into account. However, the assembly of the generator as a whole is of vital importance since a bad contact or a thermal bridge can waste the performance of an optimal generator. In this sense, the present chapter analyzes experimentally the use of different interface materials to reduce the thermal contact resistance between the modules and the heat exchangers, the influence of the pressure distribution in the assembly as well as the effect of different insulating materials in order to reduce the thermal bridge between the exchangers. Thus, it has been demonstrated that a good assembly requires the implementation of thermal interface materials to ensure the microscopic contact between the heat exchangers and the modules, besides a uniform clamping pressure. Nevertheless, since this is normally achieved with screws, they represent a source of thermal bridges in conjunction with the small distance between the exchangers. In order to reduce heat losses due to thermal bridges, which can represent up to one-third of the incoming heat, an increment of the distance between the exchangers and the use of an insulator is recommended.
