断面図である。FIG. 1 shows a heat exchanger in a first embodiment of the present invention. In Fig. 1, 8 is a connecting ladder, 9 is an inlet/outlet header, and 1o is an improved flat tube. Moreover, FIG. 2 is a perspective view of the improved flat tube 10. Third
The figure is A-A' of the inlet/outlet header 9 in Fig. 1.
FIG.

以上のように構成された熱交換器において以下第1[F
]、第2図、第3図を用いて説明する。In the heat exchanger configured as above, the following first [F
], will be explained using FIGS. 2 and 3.

ージング材より成り、コルゲートフィン2と共に組立て
られた後、炉中ロー材により一体ロー付される。First, a flat tube 1o having a cross section without a small refrigerant passage 7 in the center portion of the tube as shown in FIG. 2 is bent and formed. A communication header 8 is connected to one end thereof, and a dual-use header 9 for entrance and exit is connected to the other end. Both the communication header 8 and the inlet/outlet header 9 are made of a brazing material whose inner and outer surfaces are clad with brazing material, and after being assembled together with the corrugated fins 2, they are integrally brazed with brazing material in a furnace.

ッダ一部分9bとに分け、冷媒を遮断している。FIG. 3 shows the joined state of the header 9 for both entrance and exit after being brazed. The clad brazing material forms a fillet 6 between the flat tube 1o and the header 9 for both entrance and exit. Furthermore, the dual-purpose header 9 for both entrance and exit is formed by compression molding at the center of the pipe, with a partition 11 protruding, and a fillet 6 is also formed near the partition to divide the refrigerant into an inlet header portion 9a and an outlet header portion 9b. It's blocked.

を遮断している。The fourth factor is a perspective view of another embodiment of the dual-use inlet/outlet header 9 relative to FIG. 3. FIG. 5 is an enlarged view of the disk-shaped plate material 13. One header pipe 9 is made of brazing material with brazing material clad on both the inner and outer surfaces, and has a semicircular cut groove 12 in the center, into which a disc-shaped plate 13 is fitted, as described above. As in the example, it is joined together with the corrugated fins 2 and the flat tube 1 by brazing in the furnace. As a result, the header pipe 9 is partitioned by the plate material 13 and divided into an inlet header portion 9a and an outlet header portion 9b, thereby blocking the refrigerant.
以下第1図を用いてその動作を説明する。The operation will be explained below using FIG.
冷媒は風下側にある入ロヘソグ一部分9aから入り偏平

各冷媒小通路7を流れて出口ヘッダ一部分9bに到り。The refrigerant enters from the inlet port 9a on the leeward side and flows through the leeward side 10a of the flat tube 10, and the refrigerant liquid enters the connecting header 8 while evaporating. The refrigerants flowing through each of the small refrigerant passages 7 on the leeward side 10a of the flat tube 10 and having uneven (gas)/(liquid) ratios are mixed in the communication header 8. The refrigerant (gas)/(liquid) is made uniform again, flows through each small refrigerant passage 7 on the windward side 10b of the flat tube 10, and reaches the outlet header portion 9b.
適度な過熱度を持った冷媒ガスとして流れ出る。It flows out as a refrigerant gas with a moderate degree of superheat.

両用ヘッダー9で可能にした。In addition, in order to realize this, it is necessary to bring the inlet header 3 and the outlet header 4 to one end of the flat tube 10, and for this reason, in the conventional cassog method, the ineffective part of the 6'G1 part is As it grew larger, it became an obstacle. With this system, the inlet header 3 and the outlet header 4 can be provided with one inlet/outlet header 9.

It consists of a main tube, and by providing a partition in the center of the tube, it is possible to divide the refrigerant passage into an outgoing section and an incoming section without increasing the number of parts or requiring extra width of the flat tube. The heat exchange performance can be significantly improved.
