The invention provides an aluminum radiating sheet for heat exchangers. The aluminum radiating sheet is deodorant and hydrophilic and is adaptable to indoor units of air conditioners and the like. The aluminum radiating sheet for the heat exchanger is characterized by consisting of an aluminum base plate (1), a bottom processing cover (2), a first hydrophilic resin layer (3) and a second hydrophilic resin layer (4) in sequence; the bottom processing cover (2) is formed on the surface of the base plate (1) through conversion coating process, and the thickness of each of the first hydrophilic resin layer (3) and the second hydrophilic resin layer (4) ranges from 0.05 micrometer to 2 micrometers; besides, the first hydrophilic resin layer (3) is composed of at least one of polyving akohol resin, acrylic acid resin and sulfoacid resin, and the second hydrophilic resin layer (4) is composed of a hydrophilic resin binder (41) containing polyving akohol resin and polyoxyethylene resin, and a specified amount of TiO2 particles (42) carrying Zn.
