A heat exchanger including: an inlet portion having a first flow path through which a fluid is introduced; a main body including a shell and a plurality of tubes. The shell has an internal space and one surface that has a plurality of penetration holes and a cross-sectional area larger than a cross-sectional area of the first flow path. Each of the plurality of tubes allows the fluid to flow therethrough, and is positioned in the internal space of the shell. An expanded tube portion connects the inlet portion and the one surface of the shell and has a second flow path. The heat exchanger also includes a fluid flow distributor disposed in the second flow path to distribute the flow of the fluid. No other member is disposed between the inlet portion and the multiple ring members.
