✦ Synopsis
A i metre long prototype plate-fin condenser-boiler section was constructed with two boiling channels on either side of a central condensing channel.Liquid nitrogen is evaporated inside the boiling channel at atmospheric pressure while the condensing nitrogen at a higher pressure returns to a reboiler and evaporates again in the reboiler due to electric heating. At heat fluxes less than 6000 w/m 2 the total temperature difference for boiling and condensing heat transfer is less 1.1K,decreased by 0.3--0.8 K in comparison with the practical operating condenser-boiler.
