A heat exchanger comprising:
- a heat transfer pipe configured to guide a refrigerant;
- and
- a plurality of fins spaced apart from each other to allow air to pass in a first direction, each the plurality of fins including:
- a through-hole through which the heat transfer pipe is disposed;
- a corrugated portion formed in a zigzag shape proceeding in the first direction;
- and
- a sheet portion recessed from the corrugated portion around the through-hole, the sheet portion being parallel with the first direction,
- wherein each of the plurality of fins includes a reference region, the reference region being defined by the through-hole, the corrugated portion and the sheet portion,
- wherein within each reference region, an area of the sheet portion corresponds to 16%-25% of an area of the reference region,
- wherein each sheet portion includes:
- a first length in the first direction;
- and
- a second length in a second direction, the second direction being perpendicular to the first direction,
- wherein the second length is greater than the first length,
- wherein each of the plurality of fins further includes a connecting portion to connect the corrugated portion and the sheet portion,
- wherein each corrugated portion includes a plurality of inclined portions having an inclination with respect to the first direction,
- wherein the plurality of inclined portions of each corrugated portion includes two crest portions and a trough portion,
- wherein for each of the plurality of fins, the corrugated portion is formed in two inner inclined portions that are disposed between the two crest portions,
- wherein the trough portion is positioned between the two inner inclined portions,
- wherein the plurality of inclined portions of each corrugated portion includes outer inclined portions that define the two crest portions outside the two inner inclined portions,
- wherein for each of the plurality of fins, a length of each outer inclined portion that does not overlap with the connecting portion in the first direction is less than a length of each inner inclined portion, and
- wherein for each of the plurality of fins, the connecting portion is arranged to surround the sheet portion and separates the corrugated portion and the sheet portion.
