PROBE FOR COLLECTING THERMAL ENERGY FROM THE GROUND FOR A HEAT PUMP, AND COLLECTING NETWORK EQUIPPED WITH PROBES OF THIS TYPE

摘要

This probe (10) comprises a coolant circulation circuit with an inlet (28) and a fluid outlet (34) connected to a heat pump. This circuit comprises at least two tubes (12, 14) extending in parallel, with a fluid inlet tube (14) and a fluid return tube (12), the intake and return tubes being in communication (24) with each other at their distal ends (18, 22). These tubes are made with a common wall, over their entire length. The assembly forms a single, bendable tubular element with a free distal end. The return tube is provided with internal reliefs (44) capable of creating turbulence in the flui of circulating in this tube, while the inner wall of the fluid intake tube is smooth to promote a laminar flow of the fluid circulating therein. .
