Method and device for heat transfer
First Claim
1. A method for transferring heat, comprising:
- heating by a thermal energy source at least one evaporator tank filled with at least two different fluids, where a first fluid is in a gaseous phase and a second fluid is in a liquid phase;
causing by said heating an increase in pressure in the at least one evaporator tank and a transition of the liquid phase of the second fluid into a gaseous phase of the second fluid, which is mixed with the gaseous phase of the first fluid;
under the increased pressure in the at least one evaporator tank, providing a flow of the mixture of the gaseous phases of the first and the second fluid over at least one steam line into at least one condenser, where the gaseous phase of the second fluid is condensed with release of condensation heat to a thermal energy receiver and formation of a liquid phase of the second fluid;
under the increased pressure in the at least one evaporator tank, providing a flow of the condensed liquid phase of the second fluid mixed with the gaseous phase of the first fluid over at least one liquid line into at least one accumulation tank until pressure in the at least one evaporator tank exceeds pressure in the at least one accumulation tank;
once the entire second fluid has transited from the liquid phase to the gaseous phase in the at least one evaporator tank, while condensation of the gaseous phase of the second fluid in the at least one condenser is continuing, reducing pressure in the at least one evaporator tank to a pressure value lower than that in the at least one accumulation tank, thereby ensuring a flow of the condensed liquid phase of the second fluid and the gaseous phase of the first fluid from the at least one accumulation tank to the at least one evaporator tank through at least one non-return valve mounted on at least one return line,wherein a separator is further provided on the at least one return line to separate the mixture of the gaseous phase of the first fluid medium and the condensed liquid phase of the second fluid leaving the at least one accumulation tank into a flow of the gaseous phase of the first fluid and a flow of the liquid phase of the second fluid and to provide a delay between the arrival time of the gaseous phase of the first fluid and the arrival time of the liquid phase of the second fluid in the at least one evaporator tank, wherein the gaseous phase of the first fluid arrives first, and then the liquid phase of the second fluid arrives.

Abstract
A method for transferring heat includes: heating an evaporator by a thermal energy source; providing a flow of a mixture of gaseous phases of a first and a second fluid over a steam line into a condenser; providing a flow of the condensed mixture over a liquid line into an accumulation tank; and providing a flow of the condensed mixture from the accumulation tank to the evaporator tank through non-return valves mounted on a return line. The method ensures transferring of a large quantity of thermal energy from a source to a receiver over considerable distances without application of porous capillary materials and additional processes for forced pumping of condensed fluid, regardless of the position of the source and the receiver in the gravity field.
