<p>The present invention relates to a heat exchanger capable of improving a heat transfer performance by alternately stacking and arranging microchannel tubes having water and refrigerant flowed, and if water is leaked, guaranteeing stable operation by detecting the leak. According to an embodiment of the present invention, a heat exchanger includes an inlet side refrigerant header tank (130) having a refrigerant inlet (131) introducing the refrigerant inside; a plurality of long microchannel tubes (114) having one ends connected to the inlet side refrigerant header tank (130) and a plurality of refrigerant microchannels (113) arranged in parallel; an outlet side refrigerant header tank (135) connected to the other ends of the long microchannel tube (114) and having a refrigerant outlet (136) discharging the refrigerant outside; an inlet side water header tank (125) having a water inlet (126) introducing water inside; a plurality of short microchannel tubes (112) having the other ends connected to the inlet side water header tank (125), having a plurality of water microchannels (111) arranged in parallel, and formed in a shape shorter than the long microchannel tube (114); and an outlet side water header tank (120) connected to one ends of the short microchannel tubes (112) and having a water outlet (121) discharging the water outside, wherein each of the short microchannel tubes (112) and each of the long microchannel tubes (114) are alternately stacked to form a microchannel tube module (110).</p> |
