PURPOSE: A heat exchanger is provided to obtain high durability, fluid blocking properties, and high assemblability. CONSTITUTION: A heat exchanger comprises a case(100), a tube bundle(200), and a labyrinth seal(400). A flow path through which fluid passes is formed in the case. The tube bundle is located on a moving path of the fluid in the case and is arranged separately from the inner surface of the case. The labyrinth seal includes a plurality of protrusions. The protrusions are arranged between the tube bundle and the inner surface of the case, thereby preventing the fluid from passing through a space between the tube bundle and the inner surface of the case. |
