摘要:
A heat exchange apparatus is provided with a plurality of plates formed and stacked so at to provide heat transfer through the plates from a first gas to a second gas. The plates are of substantially identical configuration and size, each of the plates formed with a central opening and an alternating arrangement of first and second surface patterns, ports being provided between the first and second surface patterns. The plates are stacked such that adjacent plates are rotated 180.degree. about a diametrical axis relative to each other and so as to place the ports and patterns in alignment, surface patterns of the first type from any of the plates being adjacent to surface patterns of the second type on a plate adjacent thereto to form a plurality of opposing pattern pairs. Each of the first and second patterns in each pattern pair have a plurality of sinusoidally varying surface strips and a plurality of spacing ridges between the surface strips whereby the second gas flows in a generally sinusoidal path in a first direction between the first and second plates and the first gas flows in a generally sinusoidal path in a direction opposite the second gas along the other sides of the first and second plates.
