摘要： A heat exchanger including a pressure vessel and a plurality of heat exchanger tubes extending within the vessel. A tube shroud forms an annular passage between the tubes and the pressure vessel wall. A partition wall, comprising a plurality of openings normally closed by closure means, divides the passage into a fluid inlet compartment and a fluid outlet compartment. In the event the fluid pressure differential between the inlet and outlet compartments attains a predetermined value, at least some of the closure means will open to reduce the pressure differential below the predetermined value. In one embodiment of the invention, the closure means comprise flap valves. In an alternate embodiment of the invention, rupture discs are utilized as closure means.
