Method and device for heat transfer

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.
