FIG. 9 is an exploded perspective view of the flat tube A illustrating another embodiment of the structure of the flat tube A, in which the tank plates 1 and 2 in the embodiment shown in FIGS. In place of the stamped-out rib groups 1b and 2b for dividing the refrigerant flow path, which are provided respectively in the refrigerant flow path, a corrugated flow divider plate 18 made of a thin aluminum plate pleated in a direction perpendicular to the flow direction of the refrigerant is used. Both compartments a and b in flat tube A
When the evaporator is brazed and assembled, it is joined to both tank plates 1 and 2, and is used to improve the structural strength of the flat tube and the heat exchange capacity. In the above-mentioned embodiment, each pair of ribs of the stamped-out rib groups 1c and 2c provided on both tank plates 1 and 2, which tend to be located opposite each other, intersect in an X shape and are in point contact. On the other hand, the fact that they are joined by line contact contributes to such improved characteristics.

(b) The manufacturing method of fitting parts for installing piping for supplying and discharging heat transfer medium to a heat exchanger has traditionally been a process of cutting long round pipes to size, and partially converting round pipes into square pipes. In contrast, the manufacturing method of the present invention consists of the following steps: deforming the square pipe into shape, making a sealing plug for the open end of the square pipe, and brazing the plug to the open end. The manufacturing process can be extremely simplified since it consists of only the process of cutting a long pipe with a shape to a fixed size and the process of drilling a single hole for installing the pipe.

[Claims] 1. A large number of flat tubes forming a heat transfer medium flow path are stacked and combined such that the heat transfer medium outlet and inlet of each adjacent flat tube are connected to each other. A method for attaching inlet and outlet piping for a heat transfer medium to a laminated heat exchanger having a structure, the method comprises: an end plate abutting each of both laminated end surfaces of the flat tube laminate; and an end plate disposed on the outside of the end plate. A short cylindrical joint member made of metal, which has an arbitrary cross-sectional shape and has a hole for installing the piping in the cylindrical wall surface, is installed between the installed side plate as an outer wall plate of the heat exchanger. The end plate is sandwiched so as to surround the inlet (outlet) of the heat transfer medium, and is heated to a temperature higher than the melting temperature of the brazing filler metal that has been clad in advance on the surfaces of the end plate and the side plate. A method for manufacturing a heat exchanger, characterized by heating and joining these three components by brazing.
