A heat exchanger which comprises first and second heat exchangers such that tubes (4) constituting the first heat exchanger (A) and tubes (5) constituting the second heat exchanger (B) are arranged upstream and downstream respectively in a direction of air stream, fins (6) are provided between both tubes (4), (5) and ends of the respective tubes (4, 5) are inserted into and connected to tanks (2, 3), respectively. The fins (6) are formed with louvers (7A, 7B). The louvers on the fins are such that a group of the louvers (7A, 7A) formed on the fin portions of the first heat exchanger (A) are differently formed from a group of the louvers (7B, 7B) formed on the fin portions of the first heat exchanger (B). <IMAGE> |
