Abstract
Vapordynamic thermosyphon (VDT) is an efficient heat transfer device. The
two-phase flow generation and dynamic interaction between the liquid slugs
and vapor bubbles in the annular minichannel of the VDT condenser are the
main features of such thermosyphon, which allowed to increase its
thermodynamic efficiency. VDT can transfer heat in horizontal position
over a long distance. The condenser is nearly isothermal with the length
of tens of meters. The VDT evaporators may have different forms. Some
practical applications of VDT are considered.
