Heat exchanger and method of manufacturing the same

A heat exchanger comprising:

• at least one refrigerant tube configured to comprise a plurality of sections arranged in a first direction;
• and
• a plurality of heat exchanger fins arranged on the plurality of sections, wherein, for a section of the plurality of sections, a first heat exchanger fin of the plurality of heat exchanger fins is arranged adjacent to a second heat exchanger fin of the plurality of heat exchanger fins on the section,
• wherein each of the plurality of heat exchanger fins comprises:
• a first flat surface disposed perpendicular to the refrigerant tube arranged in a second direction perpendicular to the first direction,
• a second flat surface disposed perpendicular to the refrigerant tube arranged in the second direction,
• a through hole in the first flat surface and the second flat surface, the through hole configured to allow the at least one refrigerant tube to be inserted through the first flat surface and the second flat surface in the second direction,
• a first contact member configured to protrude from only one side of the first flat surface around the through hole and surround an outer circumferential surface of the refrigerant tube, and
• a second contact member configured to protrude from only one side of the second flat surface around the through hole and surround an outer circumferential surface of the refrigerant tube,
• wherein, for each of the plurality of heat exchanger fins, a pair of contact members adjacent to each other along the refrigerant tube are configured to protrude from their respective flat surfaces toward each other, wherein respective ends of the pair of contact members adjacent to each other are detached from each other,
• wherein a first flat surface of the second heat exchanger fin is disposed between first and second flat surfaces of the first heat exchanger fin in the second direction, and
• wherein the first flat surface of the first heat exchanger fin is disposed between the first flat surface and a second flat surface of the second heat exchanger fin in the second direction.
