Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2011/073761
Kind Code:
A3
Abstract:
The invention relates to a heat exchanger (7), especially a plate exchanger (8), which is thermally coupled to a geothermal probe (6). The heat exchanger (7) comprises, for the purpose of condensation of a heat transfer medium evaporated in the geothermal probe (6) under the effect of geothermal heat, an inlet opening (16) through which the evaporated heat transfer medium can be supplied and an outlet opening (22) through which the heat transfer medium condensed in the heat exchanger (7) can be discharged, the heat transfer medium being discharged through a U tube (24) connected to the outlet opening (22) of the heat exchanger (7). The U tube (24) is arranged such that an apex section (25) of the U tube (24) is arranged in the direction of gravity (20) downstream of the outlet opening (22) of the heat exchanger (7) and downstream of a discharge opening (26) of the U tube (26). The lower edge (27) of the discharge opening (26) of the U tube (24) is arranged in the direction of gravity (20) downstream of the lower edge (28) of the outlet opening (22) of the heat exchanger (7). The design according to the invention allows a substantial improvement of the effectiveness or the efficiency of the heat exchanger (7).
