摘要

PROBLEM TO BE SOLVED: To provide a heat exchanger in which brazing is surely performed between a header collection tube and a coolant pipeline while ensuring a predetermined interval between the end part of the coolant pipeline and a flat tube.SOLUTION: The end part of a coolant pipeline 57 connected to a header collection pipe 60 of a heat exchanger 30 is formed in a flat part 59 long in the shaft direction of the header collection tube 60. The flat part 59 is fixed to the header collection tube 60 by being inserted into a connection hole 64 formed in the header collection tube 60 and long in the shaft direction.
