<p>Provided is a heat exchanger having increased heat exchange efficiency obtained without obstructing the flow of fluid flowing through a fluid flow passage. A heat exchange tube (12) is provided with a flow passage forming plate (12b) for forming refrigerant flow passages (12a) by dividing the inside of the heat exchange tube (12) in the longitudinal direction. The flow passage forming plate (12b) is provided with a connection passage (12e) for connecting one of the refrigerant flow passages (12a) and the other of the refrigerant flow passages (12a) by deforming a member which constitutes the flow passage forming plate (12b). As a result of this configuration, the formation of a burr in the vicinity of the connection passage (12e) as well as the clogging of the refrigerant flow passages (12a) due to cut debris can be prevented. Consequently, the refrigerant can be passed through each of the refrigerant flow passages (12a) without deviation, and the heat exchange efficiency can be increased.</p> |
