摘要:
Known heat exchangers for switches are expensive to produce or unsuitable for heating variable surfaces. The aim of the invention is to provide a low-maintenance heat exchanger which can be produced cost-effectively in large quantities, efficiently melts snow and ice, can be connected to a geothermal heat pipe and can be used in the region of a switch, especially in a sleeper space. The invention therefore relates to a heat exchanger comprising a condensation chamber, a connecting opening for connection to a geothermal heat pipe leading into said condensation chamber. The condensation chamber is radially surrounded by a tubular main part in the longitudinal direction and has a chamber ceiling, an opposite chamber base and two sidewalls connecting the chamber ceiling to the chamber base. The main part has two end openings of the condensation chamber in the longitudinal direction, which openings are closed by respective covers.

摘要:
A method for generating mechanical energy from heat is provided. It comprises the steps of: extracting heat from a heat source; transferring the extracted heat to a heat fluid circulating in a closed heat circuit (200, 300) and evaporating the heat fluid by means of the transferred heat while increasing the pressure in the evaporated heat fluid; wherein the heat fluid under high pressure flows through a turbo-machine (22) and thereby performs work while it cools and expands; the heat fluid that has expanded and cooled after flowing through the turbo-machine is condensed again; and the pressure of the condensed heat fluid is increased again by means of the heat of the heat source, and the heat fluid is chosen such that, by using a temperature range with a maximum temperature of no more than 13°C, a vapour pressure difference of at least 0.5 MPa can be realized.
