Heat exchanger and refrigeration cycle apparatus

A refrigeration cycle apparatus comprising:

• a heat exchanger comprising:
• a plate-like fin having a windward end and a leeward end in a first direction which is along a flow direction of a heat exchanging fluid;
• and
• a first heat transfer tube and a second heat transfer tube that each extend through the plate-like fin and that are adjacent to each other in a second direction which is along a gravity direction and crossing the first direction, wherein
• an outer shape of each of the first heat transfer tube and the second heat transfer tube in a cross section perpendicular to an extending direction of each of the first heat transfer tube and the second heat transfer tube is a flat shape having a long side direction and a short side direction,
• a first end portion of the first heat transfer tube located at the windward end is disposed at an upper side in the second direction relative to a second end portion of the first heat transfer tube located at the leeward end,
• a third end portion of the second heat transfer tube located at the windward end is disposed at the upper side in the second direction relative to a fourth end portion of the second heat transfer tube located at the leeward end,
• a portion to which the plate-like fin and at least one of the first heat transfer tube and the second heat transfer tube are connected, and at least one clearance portion that separates between the plate-like fin and the at least one of the first heat transfer tube and the second heat transfer tube are disposed between the plate-like fin and the at least one of the first heat transfer tube and the second heat transfer tube,
• the at least one clearance portion is disposed at the windward end in the first direction relative to an imaginary center line that passes through a center of the first heat transfer tube in the long side direction and that extends along the short side direction, and
• wherein the at least one clearance portion is disposed to overlap with a first imaginary line segment that connects between the first heat transfer tube and the second heat transfer tube in a shortest distance and that is drawn at the most windward end in the first direction;
• and
• a fan configured to blow a heat exchanging fluid to the heat exchanger along the first direction, wherein
• the heat exchanger is disposed such that the one end of the plate-like fin is located at the windward end of the heat exchanging fluid and the second direction is along a gravity direction.
