Abstract

A heat exchanger (800) is provided which may include a first heat exchange tube (100) in a pipe shape, including a first fluid inlet (102), into which a first fluid may be introduced and flow, and a first fluid outlet (105), through which the first fluid may be discharged; a second heat exchange tube (200) that passes through the first heat exchange tube (100), including a second fluid inlet (202), into which a second fluid may be introduced and flow, and a second fluid outlet (205), through which the second fluid may be discharged; and a third heat exchange tube (300) that includes a third fluid inlet (302), into which the second fluid discharged through the second fluid outlet (205) may be introduced and flow, and a third fluid outlet (305), through which the second fluid may be discharged, the third heat exchange tube (300) enclosing an external surface of the first heat exchange tube (100).
