Thermosyphon recovery systems
A thermosyphon heat exchanger system utilizes the natural-
convection circulation of a two-phase refrigerant to transfer energy
between two airstreams.
The sealed-tube thermosyphon is similar to the heat pipe, but in-
stead of a wick relies on gravity to return the liquid refrigerant. Thus
the pipe must be installed vertically.
