PURPOSE: A heat exchanger equipped with a trapezoidal flow path is provided to minimize the occupation area by employing the trapezoidal flow path and increase the counterflow section by the heat exchange through the trapezoidal flow path. CONSTITUTION: A heat exchanger includes a heat exchange element(300), a first fan(210), and a second fan(220). The heat exchange element includes a trapezoidal heat exchange sheet, first flow paths, and second fluid paths. The first flow paths contact the heat exchange sheet and have the same trapezoidal plane as the heat exchange sheet. The second flow paths contact the heat exchange sheet, opposite to the first flow paths, and have trapezoidal plane. The first fan bypasses the air drawn in through a first suction port(110) formed on the right side of the first flow paths and discharges it to a first discharge port(130) formed on the left side of the first flow paths. The second fan bypasses the air drawn in through a second suction port(120) formed on the left side of the second flow paths and discharges it to a second discharge port(140) formed on the right side of the second flow paths. |
