PROBLEM TO BE SOLVED: To prevent a brazing filler metal of a header from flowing into an installation hole of a bracket at the time of overall brazing of a heat exchanger. SOLUTION: The invention relates to a bracket coupling structure of a heat exchanger header. The structure is obtained by providing a heat exchanger header 1 with its surface covered with a brazing filler metal, and disposing a bracket 10 having a installation hole 25 so as to be coupled to the header 1, followed by melting and hardening the brazing filler metal la to connect and integrate the header and the bracket. The bracket 10 has grooves 31 to 33 which are formed at locations between brazed portions 21a and 22a and the installation hole 25, for preventing the melted brazing filler metal 1a from flowing into the installation hole 25.
