Kind Code:
A1
Abstract:
Provided is a flux fluid with which it is possible to improve both the hydrophilicity of a heat exchanger obtained by bonding tubes to fins by brazing and the persistence of the hydrophilicity and to improve the brazeability. The flux fluid (101) is for use in producing a heat exchanger by bonding tubes (3) constituted of aluminum to fins (2) constituted of aluminum by brazing. The flux fluid (101) comprises a fluoride-based flux, colloidal silica, and a dispersion medium. The mass ratio of the colloidal silica to the fluoride-based flux is 1/200 to 1/15.
