摘要 |
A heat exchanger apparatus for accommodating thermal and pressure transients. In one embodiment, the heat exchanger apparatus comprises: a first outer shell having an open end and an end wall; an inner shell having a cavity, the inner shell extending through the end wall of the first outer shell; a first tube sheet having a rim portion having a design feature for allowing the rim portion to act as an expansion joint; the outer rim portion of the first tube sheet connected to the first outer shell so as to enclose the open end of the first outer shell and form a first header cavity between the first outer shell and the inner shell; a clearance existing between the inner shell and the first tube sheet; a plurality of holes in the inner shell that form passageways between the first header cavity and the cavity of the inner shell; a first end cap connected to the rim portion of the first tube sheet so as to form a first plenum on the other side of the first tube sheet; a plurality of tubes located in the cavity of the inner shell and operably connected to the first tube sheet; an opening in the first outer shell for flowing a shell-side fluid into and/or out of the first header cavity; and an opening in the first end cap for flowing a tube-side fluid into and/or out of the first plenum.
