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.

Cette sonde (10) comporte un circuit de circulation de fluide caloporteur avec une entrée (28) et une sortie (34) de fluide reliées à une pompe à chaleur. Ce circuit comporte au moins deux tubes (12, 14) s' étendant parallèlement, avec un tube d'admission de fluide (14) et un tube de retour de fluide (12), les tubes d'admission et de retour étant mis en communication (24) entre eux à leurs extrémités distales (18, 22). Ces tubes sont réalisés avec une paroi commune, sur toute leur longueur. L'ensemble forme un élément tubulaire enfouissable unique avec une extrémité distale libre. Le tube de retour est pourvu de reliefs intérieurs (44) aptes à créer des turbulences dans le fluide circulant dans ce tube, tandis que la paroi intérieure du tube d'admission de fluide est lisse pour favoriser un écoulement laminaire du fluide qui y circule .
