The invention relates to the field of thermal power engineering and can be used for cooling open natural and artificial sources of an aqueous medium. Also, the invention can be used for producing electrical energy by means of using the low-potential heat of open natural and artificial sources of an aqueous medium or other sources of low-potential heat. In the device, a substance which is in a closed volume is alternately in contact with a heat source (medium being cooled) and a thermal receptor (surrounding medium), necessarily undergoing phase transitions (condensation and evaporation, alternately). The energy from expansion (compression) produced in the process is converted into useful work. Useful work can be produced as electrical energy, inter alia using a magnetohydrodynamic transducer. The amount of generated electrical energy can be compared with the intrinsic consumption of a cooling system of a combined heat and power plant, a nuclear power plant, or an industrial facility. The invention makes it possible to increase significantly the effectiveness of cooling and to increase the depth of cooling. The invention makes it possible to cool open natural and artificial sources of an aqueous medium independently, without any additional energy losses.
