Se sugiere un nuevo modelo de enfriamiento termoeléctrico (efecto Peltier) en la unión de dos semiconductores. Esta teoría se basa en el análisis del principio de Le Chatelier-Braun, y en la ecuación de balance de energía en la presencia de corriente eléctrica y de flujo de calor a través de la estructura de dos semiconductores. Se obtienen las distribuciones de temperatura que ilustran el efecto Peltier.
Palabras clave: Enfriamiento termoeléctrico; Efecto de Peltier
A new model of thermoelectric cooling (the Peltier’s effect) on the junction of two semiconductors is suggested. This theory is based on analysis of the Le Chatelier-Braun thermodynamic principle and the energy balance equation in a structure created from two semiconductors across which an electric current runs. The temperature distributions illustrating the Peltier’s effect are obtained.
Keywords: Thermoelectric cooling; Peltier’s effect
