PROBLEM TO BE SOLVED: To provide a pipe brazing structure capable of reducing an influence on a shut-off valve in connecting a pipe by brazing. SOLUTION: This pipe brazing structure 1 is disposed in an outdoor machine X to connect an indoor machine Y and the outdoor machine X for air conditioning by a communication pipe. This structure comprises an auxiliary pipe 2 extending from the outdoor machine X, a brazing portion 21a formed by expanding a diameter of the end in the extending direction of the auxiliary pipe 2, and the shut-off valve 20 disposed in the auxiliary pipe 2 and capable of blocking a flow channel to a heat exchanger 11 disposed in the outdoor machine X. The auxiliary pipe 2 is disposed in a piping path between the brazing portion 21a and the shut-off valve 20, and has a heat releasing portion for dissipating heat applied to the brazing portion 21a.
