Patent ID: 7896064

Claim:
A heat exchanger, comprising: a core including a shell having a plurality of sides, and at least one fluid channel in which fluid is circulated; a housing separate from and surrounding at least a portion of each of said sides of the shell to support said sides of the shell against the pressure of fluid therein, the housing including two opposed pairs of plates, with the fingers of the plates in one of the opposed pairs being removably connected together at locations outboard of the other of the opposed pair of plates, and the fingers of the plates of the other of the opposed pairs being removably connected together at locations outboard of the one of the opposed pairs and with each plate of the housing directly engaging an adjacent side of the shell so that opposed pairs of plates engage opposed sides of the shell, wherein the plates in one pair of opposed plates do not touch the plates in the other pair of opposed plates so that clamping forces are applied to the shell and not to adjacent plates.
