A heat exchanger is provided to prevent heat exchange medium from leaking and to extend a lift span by enhancing a bonding capability of a base plate and a cover plate. A heat exchanger(60) includes a base plate(10) and a cover plate(20) having a rectangular sectional surface and hollows(50). The heat exchanger is provided at one side thereof with an inlet pipe(30) and an outlet pipe(40). The hollows are vertically provided and spaced apart from each other at regular intervals. Air having passed through the hollows is heat-exchanged with heat-exchange medium provided in the base plate and the cover plate. The plural hollows increase the contact surface with air of the heat-exchange medium, so that heat-exchange performance is increased. |
