Claims

[Claims for Utility Model Registration] An outer tube 1 and a plurality of inner tubes 3, 3. A support device for supporting each of the inner tubes 3, 3°... in the outer tube 1 with a predetermined gap between them in a multi-tube heat exchanger consisting of... , each has a size that can hold each of the inner tubes 3, and the inner tubes 3. 3. The same number of short spacers 7, 7. ..., both wall end surfaces 7a of each spacer unit 7
, 7b, the wall end faces 7a of the spacer units 7, 7 are adjacent to each other in substantially point-symmetrical portions with respect to the center O of the spacer unit 7. 7b, and are connected parallel to each other and rotatably so as to form connection points P and P, and this connected spacer unit 7
,7. Each of the inner tubes 3, 3. ... are fitted into the outer tube 1, so that the outer sides of the spacer units 7, 7°, which are located at the outermost radial direction, are close to the inner surface of the outer tube 1. A multi-tubular heat exchanger characterized in that, by inserting each spacer 7 and the inner tube 3 held in the spacer 7 into a fixed position inside the outer tube 1. Inner tube support device.
