Abstract
A heat exchanger includes a heat transfer pipe for guiding a refrigerant; and a plurality of fins which respectively have a through-hole through which the heat transfer pipe passes and are disposed spaced apart from each other to allow air to pass in a first direction, wherein the fin includes: a corrugated form portion having an inclination with the first direction which is an air flow direction; and a sheet portion comprising a surface parallel to the first direction around the through hole, the sheet portion has a first length in the first direction which is an air flow direction, and has a second length longer than the first length in a second direction perpendicular to the air flow direction.
Claims18
A heat exchanger comprising:
- a plurality of heat transfer pipes for guiding a refrigerant;
- and
- a plurality of fins disposed spaced apart from each other to allow air to pass in a first direction,
- wherein each fin comprises:
- a through-hole through which a respective one of the heat transfer pipes passes;
- a corrugated form portion having an inclination with respect to the first direction;
- a sheet portion including a surface parallel to the first direction around the through-hole;
- and
- a connecting portion connecting the corrugated form portion and the sheet portion,
- wherein the sheet portion includes:
- a first length in the first direction;
- and
- a second length in a second direction perpendicular to the first direction, the second length being longer than the first length,
- wherein, for each fin, the connecting portion has an inclination with respect to a third direction orthogonal to the first direction and the second direction, and
- wherein the connection portion is formed to surround the sheet portion.
An air conditioner comprising:
- an indoor heat exchanger that exchanges heat with indoor air;
- and
- an outdoor heat exchanger that exchanges heat with outdoor air,
- wherein at least one of the indoor heat exchanger and the outdoor heat exchanger comprises:
- a plurality of heat transfer pipes for guiding a refrigerant;
- and
- a plurality of fins disposed spaced apart from each other to allow air to pass in a first direction,
- wherein each fin comprises:
- a through-hole through which a respective one of the heat transfer pipes passes;
- a corrugated form portion having an inclination with respect to the first direction;
- a sheet portion including a surface parallel to the first direction around the through-hole;
- and through hole, and
- a connecting portion connecting the corrugated form portion and the sheet portion,
- wherein the sheet portion includes:
- a first length in the first direction;
- and
- a second length in a second direction perpendicular to the first direction, the second length being longer than the first length,
- wherein, for each fin, the connecting portion has an inclination with respect to a third direction orthogonal to the first direction and the second direction, and
- wherein the connection portion is formed to surround the sheet portion.
A fin comprising:
- a corrugated form portion having an inclination with respect to a first direction;
- and
- a sheet portion including:
- a through-hole configured to receive a heat transfer pipe therethrough;
- a surface parallel to the first direction around the through-hole;
- and
- a connecting portion connecting the corrugated form portion and the sheet portion,
- wherein the sheet portion has a first length in the first direction, and has a second length longer than the first length in a second direction perpendicular to the first direction,
- wherein the connecting portion has an inclination with respect to a third direction orthogonal to the first direction and the second direction, and
- wherein the connection portion is formed to surround the sheet portion.
