Abstract
Tubes are positioned in a shell of a heat exchanger, hot fluid flowing through the tubes. An inlet of each of the tubes for hot fluid is opened to a separate section which is provided with a clearance from a thick tube sheet secured to the shell. An inlet and outlet port of each of the tubes are positioned alternately at the tube sheet. By the provision of the separate section and alternate positioning of inlets and outlets of tubes, thermal stress arising in the thick tube sheet is made very small.
