摘要

The probe (1), to gather heat from the ground (G), has a number of heat carrier tubes (2) filled with a two-phase material to evaporate through ground heat and be condensed in a heat delivery zone. Each tube has a heat reception zone (H), a heat carrier zone (N) and a heat delivery zone (K). At least two tubes have different lengths in the heat carrier zone.
