HEAT EXCHANGER

摘要

A heat exchanger, wherein second heat exchanger plates (42) and unshown first heat exchanger plates are alternately stacked each other to alternately form high-pressure fluid passages (63) and unshown low-pressure fluid passages, the high-pressure fluid passages (63) comprise inlet fluid passages (65a, 65b) divided by inlet projected lines (50a to 50c) extending from a compressed air inlet (19) and main fluid passages (64, ...) divided by a plurality of main projected lines (49, ...) extending in the direction perpendicular to the inlet fluid passages (65a, 65b) and parallel with the longitudinal direction of the second heat exchanger plates (42), the widths (Wa, Wb) of two inlet fluid passages (65a, 65b) are different from each other, and clearances (a alpha , beta ) are formed between the downstream side ends of two inlet projected lines (50b, 50c) and the upstream side ends of the main projected lines (49, ...), whereby high-pressure fluid can be uniformly distributed to the main fluid passages (64, ...) continued to the inlet fluid passages (65a, 65b) of the high-pressure fluid passages (63) of the heat exchanger.
