#CMT# #/CMT# The geothermal probe has a heat pipe (1) closed at the bottom, for receiving a two-phase heat transfer medium e.g. carbon dioxide, and a heat exchanger (6) serving as a condenser for the heat transfer medium. An upper end piece (2) of the heat pipe that penetrates into a base (3) of a heat exchanger housing (4) includes passage openings (7) for a heat transfer medium condensate in a region of the housing base. The upper end piece of the heat pipe has a stopper (8) actuated by an actuator (10), where the stopper is formed as a valve for closing the passage openings. #CMT#USE : #/CMT# Geothermal probe. #CMT#ADVANTAGE : #/CMT# The upper end piece of the heat pipe has the stopper actuated by the actuator, so that an entry of heat into the heat exchanger housing through the heat transfer medium is prevented, and hence avoiding unnecessary extraction of heat from the ground. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a simplified longitudinal sectional view of a geothermal probe. 1 : Heat pipe 2 : Upper end piece 3 : Base 4 : Heat exchanger housing 6 : Heat exchanger 7 : Passage openings 8 : Stopper 10 : Actuator. |
