HEAT EXCHANGER, MANUFACTURING METHOD THEREFOR AND CONTROL METHOD THEREFOR

摘要

The present invention relates to a heat exchanger comprising: an inlet side refrigerant header tank (130) into which refrigerant is introduced; a long micro-channel tube (114) of which one end is connected with the inlet side refrigerant header tank (130) and through which the refrigerant flows; an outlet side refrigerant header tank (135) connected with the other end of the long micro-channel tube (114) and from which the refrigerant is discharged; an inlet side water header tank (125) into which water is introduced; a short micro-channel tube (112) of which another end is connected with the inlet side water header tank (125) and through which the water flows; and an outlet side water header tank (120) connected with the other end of the short micro-channel tube (112) and from which the water is discharged, wherein each of the short micro-channel tube (112) and the long micro-channel tube (114) is alternately stacked so as to improve heat transmission performance. In addition, the heat exchanger can sense the leakage of the water or the like, thereby improving stability.
