Field of the Invention The present invention relates to a heat exchanger and a method for manufacturing the same, and more specifically, it is a heat exchanger used in, for example, an air conditioner for automobiles or an air conditioner for houses, which is appropriately spaced. The present invention relates to a heat exchanger in which a plurality of plate-shaped fins arranged in a row and a plurality of stages of heat exchange tubes are in contact with each other and a manufacturing method thereof.

As shown in FIG. 2, a heat exchanger is known which includes a plurality of flat plate-shaped fins a arranged in parallel at regular intervals, and a heat exchange tube b having a circular cross section that penetrates these flat plate-shaped fins a. In this heat exchanger, a circular heat exchange tube b is connected to a flat plate fin a.
After being inserted into a through hole (not shown) formed in the circular heat exchange tube b, a cylindrical rod having a diameter slightly larger than the inner diameter of the circular heat exchange tube b is inserted into the circular heat exchange tube b to expand the flat plate fin. It is manufactured by bringing a into close contact with the circular heat exchange tube b.

る。As another heat exchanger, as shown in FIG. 13, a heat exchanger having a heat exchange tube c having a flat cross section in place of the circular heat exchange tube b is known. By using the heat exchange tube c having a flat cross section in this way, it is possible to prevent the pressure loss on the air side, which is the fluid whose temperature is adjusted, from decreasing in the heat exchanger having the circular heat exchange tube a.

【発明が解決しようとする課題】しかしながら、前者す
なわち、円形熱交換管ｂを有する熱交換器においては、
熱交換管が円形断面であるため、空気側抵抗が大きく、

及びファンで生じる騒音の問題があった。また、熱交換

さくすることは可能であるが、必要な熱交換性能を得る
ためには熱交換器が大きくなるという問題があった。However, in the former case, that is, in the heat exchanger having the circular heat exchange tubes b,
Since the heat exchange tube has a circular cross section, the air side resistance is large,
A large fan was required to obtain the air volume to secure the performance as a heat exchanger. Therefore, there is a problem of noise generated in the heat exchanger and the fan. Further, it is possible to reduce the resistance on the air side by increasing the distance between the heat exchange tubes, but there is a problem that the heat exchanger becomes large in order to obtain the required heat exchange performance.

率が低くなり、必要な熱交換性能を得るためには熱交換
器を大きくせざるを得なかった。In the latter case, in which the heat exchange tube is formed in a flat shape, the loss of resistance on the air side can be reduced as compared with the circular heat exchange tube b, but the flat heat exchange tube is a pressure resistant product. In order to secure the performance, it is necessary to have a cross-sectional shape having columns inside. Therefore, since there was no simple expansion means such as a heat exchange tube with a circular cross section,
The adhesion between the flat heat exchange tube c and the flat fin a becomes poor, and therefore the heat resistance becomes high and the heat exchange efficiency becomes low. In order to obtain the necessary heat exchange performance, the heat exchanger is required. I had no choice but to increase.
