Disclosed herein is a heat exchanger, and more particularly to a heat exchanger having an improved refrigerant flow structure. The heat exchanger includes a plurality of tubes arranged in a first row and a second row, a first header connected to one end of the plurality of the first row tubes and a second header connected to one end of the plurality of the second row tubes, a first baffle dividing an inside of the first header into a first channel and a second channel in a vertical direction and dividing an inside of the second header into a third channel and a fourth channel in a vertical direction, an inlet pipe connected to the second channel to allow the refrigerant to flow therein, and an outlet pipe connected to the third channel to discharge the refrigerant.

Heat exchanger

A heat exchanger includes a plurality of tubes having refrigerant flowing therein and arranged to exchange heat with outside air; and a header having a chamber adapted to distribute the refrigerant to the plurality of tubes, wherein the header includes, a base wall having a plurality of tube insertion holes into which the plurality of tubes are inserted, and a partition wall integrally formed with the base wall and configured to divide the chamber into a plurality of sections corresponding to the plurality of tubes. This structure helps reduce the number of parts of the heat exchanger, simplify processing and assembling, and improving the heat transfer performance by improving the distribution of the refrigerant.

Heat exchanger, header for the same and manufacturing method thereof

A distribution structure of a heat exchanger includes one inlet pipe connected to a header. The heat exchanger includes a first header having a first chamber and a second chamber, a second header having a third chamber and a fourth chamber, and a plurality of tubes arranged in a plurality of rows. An inlet pipe is connected to the first chamber and an outlet pipe is connected to the second chamber. A distributer distributes the refrigerant flowing into the first chamber to the tubes of the front row, the distributor includes a first separating baffle dividing the first chamber into a mixing chamber in which the refrigerant is mixed and a supplying chamber for supplying the refrigerant to the tubes, a distribution pipe communicating the mixing chamber with the supplying chamber, and a second separating baffle dividing the supplying chamber into a plurality of independent chambers.

A heat exchanger includes first and second heat exchanging units arranged between first and second header units, and a plurality of refrigerant circuits each defining a refrigerant path, through which refrigerant introduced into the first header unit is discharged out of the first header unit after exchanging heat in the first and second heat exchanging units.

A heat exchange fin in a heat exchanger is disposed between two refrigerant pipes spaced apart from each other includes a guide protrusion including first inclined planes inclined upward along opposite sides of a center line of a refrigerant pipe row in a symmetric fashion and second inclined planes inclined downward from upper ends of the first inclined planes, and the first inclined planes and the second inclined planes are provided with louver members, thereby improving heat exchange efficiency.
