連続的に行われるものである。An example of a conventional fin-tube heat exchanger will be described below with reference to the drawings. FIG. 4 shows a partial cross-sectional view of a conventional fin-tube heat exchanger. Plate fin 1
Then, heat exchanger tube insertion holes are bored and fin collars 2 are raised at equal intervals, and after the heat exchanger tubes 3 are inserted through them, they are tightly attached and fixed to the plate-shaped fins 1 by means such as tube expansion. Heat exchanger tube 3
A refrigerant is made to flow inside, and the heat is transmitted to the fins 1 from the fin collar 2 closely fixed to the heat transfer tube 3. On the other hand, when the gas flows in the direction of the white arrow 6 and passes over the fins 1, heat is exchanged due to the temperature difference between the gas, the heat transfer tubes 3, and the fins 1, and this action causes heat exchange between the refrigerant and the gas. It is done continuously.

に悪いという問題点を有していた。Problems to be Solved by the Invention Among the effects described above, when gas flows in the direction of arrow 6, 1. In the downstream portion of the heat exchanger tube 3, airflow stagnation portions, so-called dead zones 4a and 4b, occur. Especially the downstream heat exchanger tube 3
The area of the dead zone 4b that occurs downstream of the heat exchanger tube 3 is large, and heat exchange between the heat exchanger tube 3 in which the refrigerant flows as a heat source and the fin at the highest temperature near the heat exchanger tube is hindered, resulting in a very low heat exchange efficiency. It had the problem of being bad.

ができる。EXAMPLE An example of the present invention will be described below with reference to the drawings. In the figure, heat transfer tube insertion holes are bored in plate-like fins 11, fin collars 12 are stood up at equal intervals, heat transfer tubes 13 are inserted through these holes, and then the heat transfer tubes 13 are tightly fixed to plate-like fins 11 by means such as tube expansion. Configure. At the downstream part of the plate-like fin 11, there is a cut-and-raised part 16 diagonally downstream of the heat exchanger tube 13.
has been established. The effect will be explained below. A refrigerant is made to flow inside the heat exchanger tube 13, and its heat is transmitted from the fin collar 12 closely fixed to the heat exchanger tube 13 to the fins 11, so that heat exchange between the refrigerant and the gas is continuously performed. On this occasion,
The gas flowing in from the direction of the white arrow 15 is cut and raised 1
By colliding with
can be significantly reduced compared to conventional methods. Due to this effect, the area of the heat exchanger tubes 13 in contact with the airflow of the fins 11 increases, and the heat exchange ability can be greatly improved.
