Abstract
A heat exchanger is disclosed. The heat exchanger includes a heat exchanger core including a stacked plurality of plates, a top plate, and a bottom plate. The plurality of plates includes two end portion plates, and a plurality of intermediate plates stacked between the end portion plates. Each of the plurality of intermediate plates has a flow-through portion penetrating through the intermediate plates through which a fluid flows. Each of the through holes of each of the plurality of intermediate plates demarcates a flowthrough path which penetrates through the intermediate plate in the stacking direction and is isolated from the flow path between plates. A boss portion having a substantially elliptical shape edge portion is formed at each plate.
