Abstract
Heat exchangers including elongated hollow housings having inlet and outlet ports for circulating first and second fluid media through the housings and whereby each housing includes a heat exchanging core that is formed of a single, folded corrugated sheet. The sheet is formed with a series of parallel peaks and valleys running angularly to the direction of the sheet so that when the sheet is folded there are defined a plurality of channels by reason of the crisscross pattern of peaks and valleys crossing one another at right angles in the tightly folded configuration of the core. The folded configuration provides discrete respective channels for conveying the first and second fluid media. In the preferred embodiment of the heat exchangers, every fold of the corrugated sheet is in contact with the housing interior and thereby form alternating isolated channels without the need to use any top, bottom or side seals around the core. Thus, differential internal pressures in these channels are transmitted to the housing via the adjacent channel peaks which engage and then are transmitted to the housing via the folds of the sheet which are in contact with the housing.
