1. A heat exchanger, comprising:
a plurality of refrigerant tubes that extends in a horizontal direction; at least one fin coupled to the plurality of refrigerant tubes, wherein the at least one fin performs heat exchange with fluid flowing through the plurality of refrigerant tubes; and a header coupled to ends of the plurality of refrigerant tubes, wherein the header extends vertically so as to distribute a refrigerant into the plurality of refrigerant tubes, the header comprising:
a header body;a tube coupling plate coupled to the header body so as to define an interior space together with the header body, wherein the plurality of refrigerant tubes are coupled to the header body;a partition device that partitions a predetermined portion of the interior space of the header, wherein the partition device comprises:
a first partition that extends downward from an inner top surface of the header body and includes a plurality of first holes that extends therethrough;a second partition that extends downward from the inner top surface of the header body, spaced apart from the first partition in a direction towards the tube coupling plate and includes a plurality of second holes that extends therethrough; anda blocking rib that extends from the tube coupling plate into the interior space defined by the tube coupling plate and the header body and contacts bottom edges of the first and second partitions;a first flow passage formed between the first partition and an inner side surface of the header that faces the first partition;a second flow passage formed between the second partition and an inner side surface of the tube coupling plate; anda third flow passage formed between the first flow passage and the second flow passage, wherein the plurality of first holes guides the refrigerant in the first flow passage to flow into the third flow passage, wherein the plurality of second holes guides the refrigerant in the third flow passage to flow into the second flow passage, and wherein a horizontal width of the third flow passage is less than a horizontal width of the first flow passage such that the refrigerant of the first flow passage mixes in the third flow passage.
