Abstract
An internal liquid separating hood-type condensation head exchange tube, comprising an external heat exchange tube and an internal liquid separating hood disposed in the cavity of the external heat exchange tube and coaxial with the external heat exchange tube. The internal liquid separating hood is a hollow tube with a plurality of micropores or gaps distributed on a wall surface. The condensate formed during the heat exchange is pumped to the internal liquid separating hood in time under the effect of surface tension of the liquid via the micropores or gaps, and then is discharged from the heat exchange tube by the internal liquid separating hood. Vapor is retained to flow in the annular region between the external heat exchange tube and the internal liquid separating hood, so the inner wall of the external heat exchange tube comes into contact with the vapor to the greatest extent.
