Abstract
Disclosed is a plate for stack type heat exchangers and heat exchanger using such plates. A plurality of small protrusions formed on the plate are regularly arranged in the pattern of a diagonal lattice so that the ratio of the area S of the rectangle (which is defined by the longitudinal partition protrusion, a flange and two center lines passing through two neighboring round protrusion rows) to the width L of the plate falls within the range of 0.89 mm≦S/L≦1.5 mm. The outlet-side flange portion of the flange of the plate and a round protrusion of the round protrusions nearest to the outlet-side flange portion are preferably arranged so that the width Gs of the passage between the outlet-side flange portion and the nearest round protrusion falls within the range of 0.15 mm≦Gs≦1.6 mm. The several round reinforcing protrusions A are preferably situated along the lower, imaginary prolongation line of the longitudinal partition protrusion while being arranged together with the other round protrusions in the pattern of a diagonal lattice, at least one of upper protrusions of the several round reinforcing protrusions having a greater size than the size of the other round reinforcing protrusions. Two diagonal protrusions are preferably and respectively formed on both corners of the U-turn portion. A spacer inserted around the manifold portion of the manifold tubes can increase the bending moment stress of the manifold portion.
