Abstract

Considering thermoelectric refrigeration, it is remarkable how a small surface (Peltier pellet) should remove the heat emerging from a surface (surface of the place to be refrigerated) much larger than the one previously mentioned. Therefore, a problem of heat flux addressing rises. This work attempts to present, from a wide point of view, a possible device, based on the capillary phenomenon appearing in the porous media, capable of getting this heat flux addressing what makes easier the heat removal and improves the system efficiency. Furthermore, this element would improve the efficiency reached by the thermoelectric refrigerators including the current phase change devices
