Beschreibung
Zusammenfassung:	The invention provides a heat exchanger for refrigerators with corrosion resistance and hydrophilicity. The said heat exchanger for refrigerators is composed of cross fin tube which attaches the above-mentioned refrigerant piping (1) which consists of copper or a copper alloy and the above-mentioned fin material (2) in one by carrying out insertion allocation in a cylindrical collar part providedin a fin material which consists of aluminum and aluminum alloy. The 1st coating layer that consists of synthetic resins is formed in the surface of the above-mentioned cross fin tube including an outside surface of a joining section (12) of the above-mentioned collar part (21) and the above-mentioned refrigerant piping (1). A 2nd coating layer that consists of hydrophilic resin is formed in the surface of this 1st coating layer.
