Abstract (en)
[origin: WO2006111655A1] This probe (10) comprises a heat-carrying fluid circulating circuit with a fluid inlet (28) and a fluid outlet (34) that are connected to a heat pump. This circuit comprises at least two parallelly extending tubes (12, 14) of which one is a fluid admission tube (14) and the other is a fluid return tube (12), these tubes being placed in communication (24) with one another at their distal ends (18, 22). These tubes are provided with a common wall over their entire length. The assembly forms a tubular element that can be buried only with a free distal end. The return tube is provided with inner reliefs (44) capable of creating turbulences in the fluid circulating inside this tube whereas the inner wall of the fluid admission tube is smooth for favoring a laminar flow of the fluid circulating therein.
