<p>Heat exchanger, which allows differential thermal expansion of its elements while providing a bypass seal including, a shell (160) for containing a first gas, a core (110) positioned within the shell (160), and a seal (180) positioned between the core (110) and the shell (160). The seal (180) allows at least some differential expansion between the shell (160) and the core (110) while restricting the flow of the first gas past the seal. Preferably, the seal (180) is mounted to the core (110) at a position at least adjacent to the free (moveable) end or ends of the core (110). The seal (180) can be folded into several layers such that the folds abut both the core (110) and the shell (160).</p> |
