Abstract: The present invention relates to a heat exchanger comprising multiple arranged fin tubes, each of which comprises a heat transferring fin and multiple tubes integrally formed on a plate, wherein refrigerant flows through the tubes. Each of the fin tubes has a first surface forming the front surface of the fin tube and a second surface forming the rear surface of the fin tube, and has opening part which communicates with at least a side of the multiple tubes and is formed to extend through the first surface and the second surface; and the perimeters of the openings of the fin tubes adjacent to each other may be connected through a connection part such that the openings of the adjacent fin tubes communicate with each other. Therefore, there is an advantage in that refrigerant can be distributed without a separate header.

Abstract: The present invention relates to a heat exchanger comprising: a plurality of fin tubes which have heat transfer fins integrally formed with tubes in which a refrigerant flows; and a header which is coupled to the respective one end portions of the plurality of fin tubes. The header may comprise: a header main body which has one side opened; and a sheet which is disposed on the open one side of the header main body, has formed therein a plurality of slits having the respective one end portions of the plurality of fin tubes respectively inserted therein, and forms a plurality of corrugated portions by being bent into a corrugated shape. Accordingly, the respective one ends of the fin tubes are inserted into the sheet having the corrugated portions formed, and then the corrugated portions of the sheet are compressed, thereby enabling the narrowing of gaps between the fin tubes and the header, and thus, by increasing tight adhesion between the fin tubes and the sheet, tolerance may be reduced, and a leakage of the refrigerant may be reduced. In addition, when inserting the fin tubes, intervals between the corrugated portions formed on the sheet are widened so as to enable the fin tubes to be easily inserted, and thus an advantage is also achieved of enabling easy product assembly.
