According to the first feature of the present invention, the first action is achieved by forming the notch groove cut from the lower edge to the center height of the upper and lower insertion holes in the middle portion of each insertion hole in the lower stage. As a result, a part of the hot air from below rises in the cut groove without being absorbed in the lower portion of the fin, and is easily absorbed in the upper portion of the cut groove, that is, in the central portion of the fin or higher. In addition, heat can be easily transferred from the edge of the deep cut groove to the upper half of the heat exchange water passage pipe in the lower stage. Further, as a second action, since the burring hole is formed in the middle portion of each upper insertion hole above the cut groove, the hot air rising in the cut groove is diverted to the side due to the resistance of the burring hole. As a result, the heat exchange water passage pipe in the upper stage is sufficiently hit with hot air, and the heat absorption by the fins in the vicinity thereof is promoted. On the other hand, according to the above-mentioned second feature of the present invention, by forming a cut groove cut from the lower edge to the center height of the upper and lower insertion holes in the middle portion of each insertion hole in the lower stage, the first action As the above, the same operation as the first operation according to the first feature is performed. Further, as a second action, since the arcuate cut with the flange is formed on the fin upper edge above each cut groove and above the middle of each upper insertion hole, the hot air rising in the cut groove is After the rise is hindered by the flange of the arcuate cut at the upper edge of the fin, it is properly caged on the upper part of the fin and is guided to the side, and after flowing to the upper half side of the heat exchange water pipe of the upper stage Pass upwards. Therefore, the heat absorption in the upper half of the fin is promoted and the heat absorption in the upper heat exchange water passage pipe is promoted.

In the middle portion of each of the insertion holes 12 in the lower stage,
A notch groove 40 is formed by cutting from the fin lower edge 10b to the center height of the upper and lower insertion holes 11 and 12. The width of the cut groove 40 is, for example, such that the distance between the insertion holes 12 is divided into three. Further, a burring hole 50 is formed in the middle of each through hole 11 in the upper stage above each of the cut grooves 40. The height of the flange 50a of the burring hole 50 is, for example, the same as the height of the flanges 11a and 12a of the insertion holes 11 and 12, and the flanges are aligned when the fins 10 are aligned.
The 50a is in contact with the adjacent fin 10. The width of each burring hole 50 is, for example, such that the distance between the insertion holes 11 is divided into three.

The hot air rising from the lower combustion chamber (not shown) transfers heat by contacting the lower water passage pipes 22 and the fin regions below the lower insertion holes 12, while the hot air The portion rises in the middle of each insertion hole 12, along the cut groove 40, without heat transfer, the upper portion of the cut groove 40,
That is, heat is absorbed by the fin above the central portion of the fin. As a result, the degree of heat transfer through the fins to the lower water passage pipe 22 is reduced. At the same time, heat is likely to be absorbed in the upper part of the cut groove, that is, in the central part of the fin or more. Of course, also in the lower water passage pipe 22 itself, the heat transfer ratio to the lower half side of the lower water passage pipe 22 is reduced, and the cut groove 40
Since the ratio of heat transfer from the edge of the upper part to the upper half part of the lower water passage pipe 22 increases, the degree of local heating can be reduced. The hot air that has risen between the insertion holes 12 (water passage pipes 22 in the lower tiers) is prevented from being discharged upward as it is because the flange 50a of the burring hole 50 acts as a resistance, and is diverted to the side. The hot air sufficiently hits the upper water pipe 21, and heat absorption to the fin region in the vicinity thereof is promoted.
