A method of producing heat exchangers produces two heat exchangers simultaneously in one assembly line. A tube element unit (20) has a pair of intake/outlet portions (6,7) on both ends thereof, a pair of medium passages (10) communicating between a pair of the intake/outlet portions (6,7) and a cutting portion (5) in a middle portion thereof. A pair of tanks (30) are arranged on both ends of the tube element units. The tube element units are provisionally maintained by the tanks, and after brazing, two heat exchangers are separated and formed by cutting the cutting portion (5). <IMAGE> |
