<p>The probe has an inner flow tube (2) arranged coaxial to a heat exchanger tube (1) and staying in fluid communication with a ring channel (8) between the exchanger and the flow tubes in a region of probe foot. A rotatable probe head (9) is connected with the exchanger tube for supplying and discharging the flow tube. A heat carrier flows through the channel, and the flow tube comprises a heat insulation unit i.e. vacuum chamber, opposite to the channel. An end (13) of an outer jacket (4) of the flow tube is axially supported against an inner jacket (3). The probe is made of stainless steel. An independent claim is also included for a method for introducing a vacuum into a modular geothermal heat probe.</p> |
