<p>A heat exchanger and an air conditioner whose heat exchange efficiency is improved corresponding to a phase change in refrigerant. The heat exchanger (23, 42, 52) allows the refrigerant to pass through it while changing its state and has fins (61) and piping (62, 64, 65, 66, 67). The fins (61) are arranged in the direction of the plate thickness of the fins (61). The piping (62, 64, 65, 66, 67) penetrates the fins (61) in the direction of the plate thickness of the fins (61). Also, in order to increase the number of piping through which the refrigerant flows, the piping (62, 64, 65, 66, 67) is branched at least two times between a first inlet/outlet (G) to and from a heat exchange section (60) constructed from the fins (61) and second inlet/outlet (S1-S4) to and from the heat exchange section (60).</p> |
