The body of the heat exchange part is disposed across the internal air exhaust passage and the external air suction passage. The body of the heat exchange part freely rotates around a rotating shaft and has plural pores. The internal air exhaust fan and the external air suction fan execute directional air supply to rotate the heat exchange part.
