A shell and tube heat exchanger includes a tube bundle having a stationary tube sheet near one end thereof; a second tube sheet near the other end thereof; a plurality of tubes extending between the stationary tube sheet and the second tube sheet; a plurality of segmented transverse baffles located between the stationary tube sheet and the second tube sheet, the cut of each transverse baffle being located about 180.degree. from those on the adjacent transverse baffles; a double segmented auxiliary baffle located near at least one end of the tube bundle, the cut of the double segmented baffle extending substantially parallel to the cut on the adjacent transverse baffle and the auxiliary and transverse baffles being located at substantially equal intervals; and a longitudinal baffle member extending from the cut of the transverse baffles adjacent the auxiliary baffles to the corresponding cut on the auxiliary baffles.
In a shell and tube heat exchanger including a first tube sheet, a second tube sheet, a plurality of tubes extending between said first and second tube sheets, an outer shell surrounding said tubes and containing a shell inlet and a shell outlet, and a plurality of transverse baffles for directing the flow of shell side fluid between said shell inlet and said shell outlet, the improvement which comprises a first double segmented baffle positioned between said shell inlet and the adjacent tube sheet, a first longitudinal baffle member extending between said first double segmented baffle and the adjacent transverse baffle, a second double segmented baffle positioned between said shell outlet and the adjacent tube sheet, and a second longitudinal baffle member extending between said second double segmented baffle and the adjacent transverse baffle, said transverse and double segmented baffles being spaced at substantially equal intervals between said first and second tube sheets.
A tube bundle for a shell and tube heat exchanger having an external shell containing a shell side fluid inlet and a shell side fluid outlet which comprises a first tube sheet;
