<p>The heat exchanger has exchanger networks e.g. flat pipes (2) and ribs (3), surrounded by air and comprising a coating made of polymer i.e. polyurethane, with nanoscale silver particles. A barrier layer is formed between the coating and a metal i.e. aluminum alloy. The coating comprises an additive for production of a hydrophilic surface. The additive is selected from nanoscale particulate salt i.e. barium sulfate. The coating is formed as a dried lacquer i.e. dried aqueous dispersion lacquer. The barrier layer is formed as a conversion layer. An independent claim is also included for a method for production of a heat exchanger.</p> |
