ABSTRACT:
A rapid heat recuperative heat exchanger particularly adapted for use with large gas turbine engines, including a heat exchanger core which is composed of a plurality of spaced plate members. The core is supported within a skeleton framework by hanger members, the lower ends of which are slidably attached to horizontal control rods which extend through aligned openings in the core plates and which guide movement of the plates in an axial direction to the rods due to thermal expansion. Pressurized air is introduced to the core by inlet and outlet fittings on the end of the core which are of significantly greater thickness than the plate members. It is undesirable to join active heat exchange members of widely varying masses and differing cross-sections. Therefore, the end plate of the core is made of material having the same thickness as the inlet and outlet fittings. Progressing from the relatively thick end plate, the plates are gradually decreased in thickness until a desired plate dimension is achieved.
