Description

The invention relates to power engineering and instrument making, and in particular to a method of converting thermal energy into mechanical energy using the temperature difference between the liquid and the environment.

The purpose of the invention is to reduce environmental pollution heat-exchange fluids and increase the efficiency of the method.

The drawing shows a diagram of the device for implementing the method.

The device contains a series of sealed chambers 1 of variable volume, formed by an elastic-elastic film 2, insulated from each other and sequentially arranged along an infinite transmission 3 mounted on two wheels 4 and 5, the axes 6 and 7 of which are displaced relative to each other vertically. Chamber 1 is filled with a mixture of gas and its liquid solvent. The lower part of the transmission 3 with chambers 1 is immersed in the intermediate heat transfer fluid 8 and through it and the heat defining walls 9 is in thermal contact with the fluid 10. The temperatures of the fluid 10 and the surrounding gaseous medium 11 are different, and the intermediate fluid 8 has a freezing point below ambient temperature environment 11. Heat transfer walls 9 and the layer 12 of the heat-insulating liquid form a sealed vessel, part 13 of which, adjacent to the interface of the liquid - gaseous environment, is made heat-insulating. The heat exchange between the zones of immersion and ascent of chambers is limited by a vertical insulating partition 14.

through its walls is carried out, for example, using ribs 15.

When implementing the proposed method, the device operates as follows.

After spinning the wheels 4 and 5 from the external drive in the direction indicated by the arrow, the device rotates due to thermal energy. At the beginning of the immersion of the chambers 1 to the right of the axes of rotation 5 6 and 7, their temperature, volume and buoyancy are minimal due to the cooling of the chambers with the environment through the heat transfer walls 9 and the atmosphere of gases. In the process of immersion of the chambers 10, they are heated due to the heat supplied from the liquid 10 through the heat transfer, walls 9 and between. the exact liquid 8, as a result, the solubility of ammonia 15 in water decreases, gaseous ammonia is released from the solvent, water, increasing the volume and buoyancy of chambers 1.

When switching cameras 1 to the left branch. transmission 3 the process of heating and expansion of chambers 1 continues and the chambers emerge under the action of increased buoyancy forces. After the chambers 1 leave the intermediate liquid 8 through the layer 12 of heat insulating liquid, they cool in the environment 11, as a result, the solubility of ammonia in water increases, gaseous ammonia goes into solution and the volume of chambers decreases. Further, the process is continuously repeated and the movement of the wheels 4 and 5 occurs under the action of the buoyancy forces of the chambers on the left and right halves of the device. Thermal insulation partition 14 reduces 25 heat exchange between the zones of immersion and ascent of chambers 1, increasing the efficiency of the method. The walls 9 of the vessel prevent the penetration into the environment of 11 vapors of the liquid 8 and the gas of the working fluid, for example ammonia, diffusing through the elastic-elastic walls of the chambers 1.

The proposed method makes it possible to efficiently use thermal energy of a liquid in order to obtain mechanical energy in the presence of a temperature difference between it and the surrounding gas medium without intensifying the evaporation of the liquid and environmental pollution by vapors of heat-exchanging liquids and gas of the working fluid.
