Stacked Heat Exchanger

Abstract

To improve productivity in a lamination type heat exchanger in which plates and frame materials configured to match with an outer periphery of the plates are laminated alternately.SOLUTION: In a lamination type heat exchanger, flat plates 1 and frame materials 2, which substantially match with an outer peripheral edge of the flat plate 1, are alternately laminated to form first passages 3, in each of which a first fluid 6 circulates, and second passages 4, in each of which a second fluid 7 circulates, alternately in a lamination direction. The frame material 2 is formed by multiple divided portions and at least one of the multiple divided portions is formed as a rod-like body 2a.SELECTED DRAWING: Figure 1
