Abstract

PURPOSE: To relieve a stress caused by temperature difference and pressure difference to appear at the end of the tube plates by providing partially double tube for the heat transmission tube at a multiple tube type heat exchanger.
CONSTITUTION: High temperature fluid flows into the tube of the tube group 6 from the inlet 1, a part of which outflows to an exit 2b along the tube group 5 which is partially comprising double tube with tube group 6, the other part outflowing to the other exit 2b as passing through the annular clearance of double tube. Heat exchanging low temperature fluid flows within the shell 8 having an exit and an inlet port 3, 4. Consequently, at both ends of tube plate 7a suspending the tube group 6 a pressure difference and temperature difference are approximately equal to the pressure loss of high temperature fluid passing through double tube and the amount of heat exchanging with low temperature fluid, causing to make small difference. This enables to relieve a stress caused by pressure difference and temperature difference. Besides, the temperature difference of tube plate 7b suspending tube group 5 may be lowered to the amount of said heat exchange.
