    摘要： PURPOSE: To provide an acidic detergent for a chemical conversion film of a heat exchanger which is capable of forming the good chemical conversion film by removing the segregated matter caused by a brazing filler metal existing on the surfaces of the fins and tubes of the heat exchanger made of aluminum to clean these surfaces, a method for pickling the heat exchanger, a method for treating the heat exchanger including the pickling method and the heat exchanger formed by the treating method. CONSTITUTION: The heat exchanger, such as a car evaporator, is pickled by using the acidic detergent which is an aqueous solution containing at least one of the metal and/or metal acid salt selected from iron, nickel, cobalt, molybdenum and cerium and nitric acid and/or sulfuric acid and is then subjected to chemical conversion film formation and hydrophilic film formation. The chemical conversion film and the hydrophilic treatment film are formed after the pickling method.
