PROBLEM TO BE SOLVED: To provide a heat exchanger in which a refrigerant inlet and a refrigerant inlet pipe, a refrigerant outlet and a refrigerant outlet pipe can be simultaneously brazed well.SOLUTION: An evaporator comprises a refrigerant inlet header part 5 and a refrigerant outlet header part 6 arranged side by side in an aeration direction; and a refrigerant circulation passage communicating both the headers 5, 6. One end of the refrigerant inlet header part 5 is formed with a cylindrical refrigerant inlet 7 and the same end as that of the refrigerant inlet 7 at the refrigerant outlet header part 6 is formed with a cylindrical refrigerant outlet 9. The end part of a refrigerant inlet pipe 8 is inserted into the refrigerant inlet 7 and brazed. The end part of a refrigerant outlet pipe 11 is inserted into the refrigerant outlet 9 and brazed. Each of an outer peripheral surface of the insertion part inserted into the refrigerant inlet 7 at the refrigerant inlet pipe 8 and an outer peripheral surface of the insertion part inserted into the refrigerant outlet 9 at the refrigerant outlet pipe 11 is formed with brazing storing parts 17, 18 for storing the brazing material.SELECTED DRAWING: Figure 2 |
