On the basis of studies carried out during the Progetto Finalizzato Energetica 2, an unconventional system for heat extraction from a geothermal aquifer without fluid withdrawal has been conceived and developed. In the system a special two-phase thermosyphon, called a geothermal convector (GTC), is used. This device operates with a downhole evaporator and a condenser at the ground level. In this paper the problems of this application are described: the fundamental elements for determining the device performance and the thermal design criteria are reported. Moreover, a method for designing the system for activating the geothermal fluid convection inside the well is given. Finally, to exemplify the possible results of this design procedure, a GTC prototype, in an advanced stage of realization, is described.
