There is a heat exchanger shown in No. 99290, and as shown in FIGS. 1 and 2, a pair of tube sheets A,
Both side flanges B, B of A are connected to a pair of side plates C, C
When used as a heat exchanger for a water heater, etc., the heat exchanger tube E and the heat exchanger tube E, which have cold water inside, are welded and fixed so that the cold water in the heat exchanger tube E is heated by the combustion hot air of the burner D. In contrast, the difference in thermal expansion between the burner D and the side plate C, which has a higher temperature than that of the burner D,
By repeating heating and cooling by turning on and off,
In addition, since the heat exchanger tube E and the side plate C are formed thicker than the fins F, the welded portion G between the tube sheet A and the heat exchanger tube E hardens and eventually cracks occur. have some inconvenience.

る。 The purpose of the present invention is to eliminate such inconveniences and provide a heat exchanger with good durability. In the case where a large number of fins 5 having notches 4 are provided and a welding member 6 is inserted into the notches 4 and welded and fixed, the tube sheets 1, 1
It is characterized in that a pair of adjacent fins are composed of fins 5A, 5A without a notch. In FIG. 3, a large number of fins 5 have a fin collar 3 through which a heat transfer tube 2 through which cold water passes is inserted, and a notch 4 connected to the fin collar 3 into which a rod-shaped welding member 6 is inserted. FIG. 4 shows a fin 5A without a notch, and only a fin collar 3A through which the heat transfer tube 2 is inserted is provided. The plurality of fins 5 and the fins 5A without notches have bent edges 7, 7 and 7A, 7A in a direction opposite to the protruding direction of each fin collar 3, 3A. The large number of fins 5 and the fins 5A without notches have the same thickness, and the through holes 8 provided in the pair of tube sheets 1, 1, which are thicker than this, and the respective fin collars 3, 3A. The inner diameter of the heat transfer tube 2 is slightly larger than the outer diameter of the heat transfer tube 2. The structure of the heat exchanger according to the present invention will be explained with reference to FIG. After setting one tube plate 1, one fin 5A without a notch, and a large number of fins 5 in this order using a jig, etc., heat transfer tube 2 is inserted into through hole 8 and each fin collar 3A, 3.
Insert into. Next, the welding member 6 is inserted into the notches 4 provided in the multiple fins 5. Thereafter, the remaining fin 5A without a notch and the remaining tube plate 1 are inserted and set into the heat exchanger tube 2 in this order, and the heat exchanger tube 2 is expanded and fixed. Finally, the bent tube 9, the heat exchanger tube 2, the flange portion 10 of the tube sheet 1, and the side plate 11
are temporarily fixed by welding, etc., and then welded in a high-temperature furnace. Reference numeral 12 denotes a burner, and the cold water in the heat transfer tube 2 is heated by the hot combustion air.

効果を有する。 As explained above, the welding member 6 has a length that is accommodated between the pair of uncut fins 5A, 5A, and even when welding in a high-temperature furnace, the welding member 6 is adjacent to the tube sheets 1, 1. Since the pair of fins 5A and 5A have no notches, the molten welding member 6 does not flow into the tube sheet 1, and the tube sheet 1 and the heat exchanger tube 2 are not welded. Therefore, as mentioned above, by repeatedly heating and cooling by turning the burner ON and OFF, the weld between the tube sheet and the heat transfer tube hardens and eventually cracks. It has the effect of providing an exchanger.
