Abstract

Surface treatment of Al (alloy) heat exchangers, supplied with air, to improve the removal of condensed water, in exchangers in which the dimension of the surface extension elements is smaller than the diameter of a drop of condensed water, is by immersing the surface of the heat exchanger at 60-90 degrees C in an aq. mineral soln. of slight alkalinity to which inhibitors have been added.
