However, there is a drawback in that the expanded tube cannot be inserted into the insertion hole of the side plate. Also, the number of tubes to be installed is limited by the number of insertion holes provided in the side plate, and for example, only four tubes can be installed in the side plate with four insertion holes.
It has the drawback that a heat exchanger with a large capacity or a heat exchanger with a small capacity cannot be built as needed, and it is difficult to insert a tube of the same external shape as the size of the insertion hole into the insertion hole of the side plate, and it is assembled. It had the drawback of being difficult. Further, there is a drawback that the surface area of heat exchange by fins is small and the heat exchange is relatively small.
