The present disclosure relates to a heat exchanger and an air conditioner including the same. The heat exchanger may be provided for heat exchange between refrigerant and air. The heat exchanger may include a plurality of refrigerant tubes that are disposed with a clearance (C) therebetween in a first direction (A), in which the air moves, and are disposed to be spaced apart in a second direction (B) crossing the first direction (A) and a plurality of heat exchange fins that are disposed between the plurality of refrigerant tubes disposed to be spaced apart in the second direction (B).

Heat exchanger and air conditioner including same

Disclosed are a heat exchanger and an air conditioner including heat transfer tubes configured to guide a refrigerant, and a plurality of fins installed through which the heat transfer tubes penetrate and arranged to be spaced apart from each other in a second direction perpendicular to a first direction such that air passes through the fins in the first direction, wherein the plurality of fins each includes a plurality of inclined portions connected to each other in a zigzag form and inclined with respect to the first direction, and a plurality of louvers formed by being bent to form an angle with the inclined portions after portions of the plurality of inclined portions are cut, wherein a width of each of the plurality of louvers in the first direction after being bent is equal to or less than a width of the louvers in the first direction before being bent.

Heat exchanger and air conditioner having the same

Disclosed herein is a heat exchanger including a corrugated fin and an air conditioner including the same. The corrugated fin includes a through hole through which a heat transfer tube passes, a corrugated portion formed in a zigzag shape in the first direction corresponding to an air flow direction and a flat portion provided in the plane adjacent to the through hole, and the flat portion has a first length in the first direction corresponding to an air flow direction, and a second length shorter than the first length in a second direction perpendicular to the air flow direction.

A heat exchanger according to an embodiment of the present disclosure and an air conditioner having the same include a heat transfer tube through which a refrigerant passes, a fin having a mounting hole in which the heat transfer tube is installed, and a fin collar extending from the mounting hole and being in contact with the heat transfer tube by the expansion of the heat transfer tube, wherein the fin collar includes a base portion provided adjacent to the fin and extending to be bent at a first curvature radius, and a distal end located on the opposite side of the base portion and extending to be bent at a second curvature radius smaller than the first curvature radius.

The present disclosure relates to a heat exchanger and an air conditioner improving heat exchange ability by optimizing the number of high protrusions of a heat transfer tube and a height difference between the high protrusion and a low protrusion to increase the heat transfer performance of the heat transfer tube or reduce the pressure loss in the tube. An air conditioner includes the heat exchanger including a heat transfer tube configured to allow the refrigerant to flow, fins installed on the heat transfer tube, and fin collars forming an insertion hole through which the heat transfer tube is inserted and passes, and the fin collars is in contact with the heat transfer tube by tube expansion of the heat transfer tube. The heat transfer tube includes high protrusions disposed in a spiral shape with respect to a tube axis direction of the heat transfer tube, twenty one to twenty seven of the high protrusions being formed along a circumferential direction of the heat transfer tube, and low protrusions disposed between two of the adjacent high protrusions along the circumferential direction of the heat transfer tube and having a height lower by 0.03 mm to 0.05 mm than the high protrusions.
