Heat exchanger

Abstract

A heat exchanger may include a laminated body, a bottomed cylindrical case housing the laminated body, and a base plate. The laminated body may include a plurality of plates, a first fluid flow path, and a second fluid flow path. The flow paths may be formed via lamination of the plates. The case may include an opening disposed on a side of the laminated body, a side wall part covering a side surface of the laminated body, a top face part disposed on a side of the case facing the laminated body, a sloped surface part extending at an inclination relative to the side wall part, and an inlet and/or an outlet for passage of a first fluid. The sloped surface part may be contiguous to the side wall part and to the top face part. The inlet and/or the outlet may be disposed on the sloped surface part.
