ペースト状ろう材は完全充填されている。(See Figure 3) ■ Since the paste filler metal is filled into the recess, when the tip of the bottle falls into the recess during stacking, the paste filler metal overflows from the recess and surrounds the outer periphery of the bottle tip (see Figure 4, 22). ),
Forms a good fillet after brazing. (Fig. 5 23
(Refer to) Q: The depth of the recess is set depending on the amount of variation in pin fin length (
By setting the filler metal to be more than 100% (which is originally small due to the effect (2)), the variation is completely absorbed and the short pin fins are completely filled with the paste brazing filler metal.

Since the fillet portions 23 and 23 are formed, the fin strength is increased and heat flow from the flat plate to the bin fins is effectively achieved.

A depression 1 is formed on both sides of the flat plate on the n'-n' axis that coincides with the n-n axis.
The members provided with 8A and 18B are laminated alternately and brazed. The brazing filler metal can be applied using the same method as shown in FIG. This example has almost the same effect as the example], but requires two types of molds. That is, for the member <al, a ram similar to the die 13 of FIG. 1 is required, and for the member fbl, a lower die similar to the ram 15 of FIG. 1 is required.

る。Therefore, it is sufficient to insert a sheet-shaped brazed foil as a brazing material. On the other hand, there is a drawback that the central axes of the bin fins 17 in each stage are misaligned, but the number of parts can be drastically reduced compared to the conventional method shown in FIG. 10. <Effect of the invention> From the above explanation As is clear, the bin fin heat exchanger with the laminated structure of the present invention has a plurality of bin fins of fixed shape, size, and arrangement on the front and back sides of the heat exchanger plate in a continuous and integral manner so that their central axes coincide with each other. At the same time, another heat exchanger plate is arranged parallel to and at a certain distance from this heat exchanger plate so as to face this heat exchanger plate. Since flat plates with concave portions of the same diameter are stacked one on top of the other, there is no misalignment between the heat transfer paths of high-temperature gas and low-temperature gas, allowing effective heat exchange. The manufacturing method is also extremely simple, as the tip of the bottle fin provided on the first heat exchanger plate can be fitted into the recess of the second heat exchanger plate, and the two can be joined by a method such as brazing. Can be done.
