Abstract
The invention relates to a heat exchanger for use as a reboiler-condenser which increases the efficiency of heat transfer between boiling and condensing fluids such as cryogens, e.g. oxygen and nitrogen in an air separation unit. The exchanger has enhanced boiling and condensing surfaces and slightly inclined condensing passages built up from individually extruded passageway elements.
