Ground probe for recovering heat, has pipes arranged concentrically around central pipe and connected with each other, where probe is made of stainless steel and sum of nominal sizes of all pipes is larger than nominal size of central pipe
The probe has a set of pipes arranged concentrically around a central pipe (1), where the pipes are connected with each other, and the probe is made of stainless steel. The sum of nominal sizes of all the pipes arranged around the central pipe is larger than the nominal size of the central pipe. A venturi-nozzle (5) is arranged at the transition of a lower drum (4) in the central pipe for increasing the flow rate. The central pipe is guided through an upper drum (3) and the lower drum, where borehole depth is adjusted in the central pipe.
