METHOD FOR PROTECTING A HEAT EXCHANGER AGAINST CORROSION, AND HEAT EXCHANGER AND LIQUID COMPOSITION FOR PROTECTING A HEAT EXCHANGER AGAINST CORROSION

摘要

A method for protecting a heat exchanger against corrosion, comprising a number of plate-shaped metal fins spaced apart with intermediate slits, which are in heat exchanging contact with a number of tubes, wherein the free external surface of fins and tubes is at least partly covered with a metal containing coating, wherein the coating is applied by flowing a metal containing coating agent as a liquid flow over the external surface.
