| 摘要 |
The invention relates to a heat transfer unit (1) for heating systems and surfaces, which can be connected to at least one geothermal energy probe (2 1) as a heat source (2) operating with a multi-phase working fluid and to a component to be heated, and which comprises at least one heat exchanger (11) and transport lines (12) for the gaseous or liquid working fluid. At least one gas-tight heat exchanger (11) is designed in module form having a plural ity of directly adjoining modular mini-channels (111), depending on the powe r requirements, in a planar arrangement for transferring the latent heat ari sing from the heat source (2) from the heated gaseous portion of the working fluid to the component (3) to be heated, said mini-channels (111) being con nected to at least one supply channel (114, 115) and having a diameter of 0. 3 to 6 mm. The heat transfer unit (1) can be integrated into the region of a switch blade (32) as a railway point heater. |
