Abstract

Experimental data on the nature, thermophysical parameters, and boiling modes of closed two-phase evacuated water-filled thermosyphons are presented, and their application prospects are discussed. The high efficiency of thermosyphons in slug and hyperslug modes is experimentally confirmed.
