  • Modular air-to-air heat exchanger
    Patent number: 5660228
    Abstract: A modular air-to-air heat exchanger is provided in which heat exchanger cores are assembled in stacks from elemental core blocks that may be locked to a limited number of panels which form a variable size enclosure for the cores. Single and double width panels, half the height of the stacks, allow a staggering panel insertion which segregates crossing input and exhaust streams for an arbitrary configuration of cores.
