Claims

[Scope of utility model registration request]

(1) In the mounting structure of a finned heat exchanger tube to an intermediate support plate disposed between tube sheets, the heat exchanger tube is composed of a double tube consisting of an outer tube provided with fins and an inner tube in contact with the inner side of the outer tube, and the The outer tube is divided into predetermined lengths, the divided outer tubes are arranged on both sides of the attachment hole of the intermediate support plate, and the inner tube is arranged so as to pass through the attachment hole of the intermediate support plate and the outer tubes on both sides thereof. A heat exchanger tube mounting structure characterized in that the tubes are arranged and fixed to each other by expanding the inner tube.

(2) The inner surface of each mounting hole of the intermediate support plate has a center portion that is slightly smaller in diameter than both sides, so that the ends of the divided outer tubes disposed on both sides of the mounting hole are The heat transfer tube mounting structure according to claim 1, which is sandwiched between the inner peripheral portion of the mounting hole and the inner tube.
