ABSTRACT:
This invention relates to shell and tube heat exchangers and similar equipment and is particularly concerned with an improved arrangement for sealing the longitudinal edges of the pass baffle with the inner wall of the shell in such a manner as to prevent fluid leaks through that juncture which have the effect of bypassing the heat exchanger. The invention also relates to an improved tube bundle design wherein an aligned notch or indentation is provided in each of the tube bundle cross baffles adjacent the longitudinal edges of the pass baffle to yield a measure of protection for the edge of the pass baffle when the bundle is removed from the shell for maintenance purposes and to an optimized tube bundle configuration which may be readily reversed or rotated to extend its service life.
