ABSTRACT:
A plate-type heat exchanger consisting of pairs of plates having longitudinal and transverse corrugations and forming a sinusoidal cross section with each pair of plates defining between them flow channels through the corrugations thereof. The corrugations in the longitudinal direction of the two plates of a plate pair register with one another whereas the corrugations in the transverse direction of a first plate are offset from the transverse corrugations of a second plate by half a wavelength (spacing of corresponding points of successive corrugations) while between the plate pairs bars are disposed which run along longitudinal corrugations of successive plate pairs and thus form longitudinal channels of an undulating flow pattern. Each plate of one of the plate pairs is mirror-symmetrical to or a mirror image of the closest plate of the next plate pair.
