O Utility Model Registration Claims (1) A finned heat exchanger tube block in which a plurality of heat exchanger tubes arranged at a predetermined pitch are inserted into a plurality of plate fins arranged perpendicularly to the heat exchanger tubes at a predetermined pitch. In a heat exchanger in which a plurality of blocks are arranged side by side in close contact with the plate fins, and each of these blocks is held together by columnar supports from both sides of the ventilation opening/exit surface parallel to the plate fins and housed in the frame, the space between the plate fins is A tube support made of thick material with heat exchanger tube insertion holes in the same arrangement as the plate flon is placed at the position where the columnar support is held, and the tube supports between adjacent blocks are brought into contact with each other. , a heat exchanger characterized by being integrally held by columnar supports on both sides. (2) Practical use characterized in that rounded portions are formed at the four corners of the tube supports that are in contact with each of the finned heat exchanger tube blocks arranged in parallel, and bands are wrapped around the outer periphery of these tube supports and fastened together.
