Beschreibung
Zusammenfassung:	The invention discloses a preparation method of an acid salt spray corrosion resistant aluminum alloy plate-fin heat exchanger. Comprising the following steps that A, chromate passivation treatment is conducted on an air cavity of the aluminum alloy plate-fin heat exchanger; and B, the surface of the air cavity subjected to chromate passivation treatment is subjected to paint dipping treatment. The acid and salt mist resistance of the aluminum alloy plate-fin heat exchanger can be improved. 本发明公开了一种耐酸性盐雾腐蚀铝合金板翅式换热器的制备方法。包括下述步骤:A.对铝合金板翅式换热器的空气腔进行铬酸盐钝化处理；B.对进行铬酸盐钝化处理的空气腔表面进行浸漆处理。本发明能够提高铝合金板翅式换热器耐酸性盐雾能力。
