うに、配置される。The heat exchanger is configured to exchange heat with the medium outside the tube while the medium inside the tube flows through the tube. For example, in a heat exchanger in which a pair of header pipes are interconnected by multiple tubes, the media flows from one header pipe through the tubes to the other header pipe, and through the other tube. It returns to the said one header pipe, and further returns to the said other header pipe through another tube and is discharged to the outside. In order to form such a flow path, the inside of the conventional header pipe has been partitioned by a disc as disclosed in JP-A-60-101483. The discs are arranged such that the pressure drop of the medium in the tube is as small as possible and the heat transfer coefficient between the medium and the tube is maximized.
