Thermosyphon principle
Thermosyphon principle, thermosyphon circuit. Heating a liquid at the lowest point of a closed circuit and cooling the liquid at the highest point creates a circulation of the liquid caused by the difference in weight of the two liquid columns. A thermosyphon circuit is produced only when the warm pipeline rises continually and the cold pipeline falls continually. Reducing the flow resistances in the circuit to an absolute minimum reduces the size of the temperature differential needed for the circulation, decreasing the load on the circuit components. Functional principle of the thermosyphon circuit
