Abstract
A heat exchanger includes a plurality of cooling plates, a duct plate disposed around the cooling plates and a spacer plate fixed to both the duct plate and the cooling plate to prevent supercharged air from flowing into a gap between the duct plate and the cooling plate. The cooling plate includes cup portions allowing cooling water flow paths of the corresponding two cooling plates to be in communication with each other when the cooling plate is fixed to the adjacent cooling plate. The cooling water flow path formed in the cooling plate includes flow path portions and formed extending in a direction perpendicular to a flow direction of supercharged air from the corresponding cup portions. The cup portions are each formed in a tubular shape having a central axis at a position offset along the flow direction of the supercharged air from a center of the corresponding one of the flow path portions in a flow path width direction.
