Description

1

The invention relates to the field of energy on the basis of renewable sources, and more specifically to power plants using an increase in ambient temperature with altitude, such as warm surface and cold deep sea waters.

The aim of the invention is to increase efficiency by using the heat of the environment and reducing energy costs for the circulation of the working fluid.

FIG. 1 shows a heat energy conversion system with a magnetodynamic generator; in fig. 2 - system with a turbine generator.

The thermal energy conversion system contains separation tank 1 with space 2 of electrically conductive liquid working fluid and steam space 3 of low boiling working fluid, condenser 4 with cooling surface, connected by steam pipe 5 to steam space 3 and through lowering flow channel 6 of low boiling working fluid to mixer 7 (Fig. 1). The latter is connected through the lifting channel 8 to the space 2 of an electrically conductive liquid working fluid. The system is equipped with a downstream channel 9 of an electrically conductive liquid working fluid connected to space 2 and a mixer 7 and containing successively along the course of a liquid electrically conductive working medium, cooler 10, cooling surface of the condenser 4, heater 11 and magnetodynamic generator 12. The cooler 10 is located on the lower level environment with low temperatures and is connected to the latter by the cooling coolant, and the heater 11 is placed at the upper level of the environment with high temperatures and under oedinen to last for heating medium. The system may also include a turbo generator 13 placed in the steam line 5 (FIG. 2).

The heat energy conversion system operates as follows.

Electrically conductive liquid working fluid under the pressure of the hydrostatic column flows down from the space 2 of the tank 1 through the downstream channel 9 and enters the cooler 10, in which it is cooled due to heat removal to the lower layers of the environment with low temperatures. Next, the electrically conductive working fluid is directed to the cooling surface of the condenser 4, where it receives the heat of condensation of the low boiling working fluid. The conductive working fluid is then heated to heat.

The body 11 due to the supply of heat from the upper layers of the environment with high temperatures and passes through a magnetodynamic generator 12, in which electric power is generated. From the latter, through the downstream channel 9, the electrically conductive working fluid enters the mixer. At the same time, the vapor of the low boiling working fluid through the steam line 5 is directed from the space 3 of the container 1 to the condenser 4, where it condenses. From the latter, the condensate of the working fluid under the pressure of the hydrostatic column enters downstream channel 6 into the mixer 7. In the mixer, the condensate of the low-boiling working medium comes into contact with a liquid electrically conductive working medium and boils due to its cooling. The two-phase mixture of working fluids rises along the lifting channel 8 into the tank i, where they are separated. When using a turbogenerator (Fig. 2), a pair of low-boiling working fluid is sent from tank 1 to turbogenerator 13, expands therein with useful work and enters condenser 4. Sodium-potassium alloy can be used as an electrically conductive working fluid or salt solution, and as a low-boiling working medium - xenon, freons, and so on.

The invention will improve efficiency by using the heat of the environment and reducing the energy costs of circulating the working fluid.
