    • Computational and experimental study of a complete heat dissipation system using water as heat carrier placed on a thermoelectric generator 

      Aranguren Garacochea, Patricia Upna; Astrain Ulibarrena, David Upna; Pérez Artieda, Miren Gurutze Upna (Elsevier, 2014)   Artículo / Artikulua  OpenAccess
      The heat dissipation systems which have liquids as heat carriers outperform conventional dissipation systems at thermoelectric generators (TEGs). However, new elements need to be introduced such as pumps, secondary heat ...
    • Development and experimental validation of a thermoelectric test bench for laboratory lessons 

      Rodríguez García, Antonio Upna; Astrain Ulibarrena, David Upna; Martínez Echeverri, Álvaro Upna; Aranguren Garacochea, Patricia Upna; Pérez Artieda, Miren Gurutze Upna (OmniaScience, 2013)   Artículo / Artikulua  OpenAccess
      The refrigeration process reduces the temperature of a space or a given volume while the power generation process employs a source of thermal energy to generate electrical power. Because of the importance of these two ...
    • The importance of the assembly in thermoelectric generators 

      Araiz Vega, Miguel Upna; Catalán Ros, Leyre Upna; Herrero Mola, Óscar; Pérez Artieda, Miren Gurutze Upna; Rodríguez García, Antonio (IntechOpen, 2018)   Capítulo de libro / Liburuen kapitulua  OpenAccess
      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 ...
    • Influence of temperature and aging on the thermal contact resistance in thermoelectric devices 

      Rodríguez García, Antonio Upna; Pérez Artieda, Miren Gurutze Upna; Beisti Antoñanzas, Irene Upna; Astrain Ulibarrena, David Upna; Martínez Echeverri, Álvaro Upna (Springer, 2020)   Artículo / Artikulua  OpenAccess
      During thermal design in the first phases development, thermoelectric systems, such as thermoelectric generators, the most important parameter affecting the performance is thermal resistance of the components. This paper ...
    • New opportunities for electricity generation in shallow hot dry rock fields: a study of thermoelectric generators with different heat exchangers 

      Catalán Ros, Leyre Upna; Aranguren Garacochea, Patricia Upna; Araiz Vega, Miguel Upna; Pérez Artieda, Miren Gurutze Upna; Astrain Ulibarrena, David Upna (Elsevier, 2019)   Artículo / Artikulua
      Despite being one of the largest renewable sources, geothermal energy is not widely utilized for electricity generation. In order to leverage shallow hot dry rock (HDR) fields, the present paper proposes an alternative to ...
    • Revisión sobre nitruraciones láser de aleaciones de titanio 

      Pérez Artieda, Miren Gurutze Upna; Fernández Carrasquilla, Javier Upna (CENIM, 2010)   Artículo / Artikulua  OpenAccess
      Una técnica comúnmente utilizada para la mejora de la resistencia a desgaste de las aleaciones de titanio es la nitruración de la superficie, utilizando la deposición física o química de vapor, la implantación iónica o el ...
    • Revisión sobre recubrimientos láser de aleaciones de aluminio 

      Pérez Artieda, Miren Gurutze Upna; Fernández Carrasquilla, Javier Upna (CENIM, 2008)   Artículo / Artikulua  OpenAccess
      En este artículo se presenta un trabajo de revisión bibliográfica, centrado en los procesos de recubrimiento y tratamiento superficial láser realizados en aleaciones de aluminio. Estos procesos láser son técnicas de ...
