A heat exchanger having an outer shell with an elongated, semi-circular fluid duct plate mounted in the shell. A tube bundle slidable between the duct plate and the shell is fixed at one end relative to the shell. The fluid inlet and outlet configuration, and transverse fluid flow pattern, are typical of those described in U.S. Pat. No. 3,532,160. The exterior of the tube bundle is partially covered with a shrouding to contain the fluid flow within the tube bundle by allowing the fluid to exit only through the outlet side. Sealing mechanisms running longitudinally between the shrouding and the upper duct plate, and between the shrouding and the shell, provide a seal which restricts the fluid flow to a transverse flow through the tube bundle. A seal between the supported end of the tube bundle and the shrouding confines the fluid flow in the bundle and allows for relative expansion of the shrouding and the bundle. Drains are provided in the shell wall on each side of the lower sealing mechanism to allow for moisture run-off from the heat exchanger.
In a heat exchanger of the type comprising a shell having a fluid inlet and a fluid outlet, a tube bundle longitudinally positioned in a spaced relation to said shell, and means directing fluid flow transversely through said tube bundle from an inlet side to an outlet side thereof, the improvement comprising:
In a heat exchanger of the type comprising a shell having a fluid inlet to said shell and a fluid outlet from said shell, a tube bundle extending longitudinally within said shell along a first axis, said tube bundle being positioned in spaced relation to said shell to provide a fluid inlet to said bundle on one side only thereof and a fluid outlet from said bundle on the opposite side only thereof, and means for directing the flow of fluid from said shell inlet only to said inlet side of said bundle and transversely through said bundle in a direction generally normal to said first axis once and in one direction only to said outlet side of said bundle and then from said outlet side of said bundle only to said shell outlet, said inlet and outlet sides of said bundle extending longitudinally substantially the full length thereof, the improvement comprising:
