Abstract:
A heat exchanger includes: multiple flat tubes that extend in a second direction intersecting a first direction which is an air flow direction and that are disposed at intervals in a third direction that intersects the first direction and the second direction; and multiple plate-like heat transfer fins that extend along the third direction and that are disposed at intervals along the second direction. The heat exchanger causes refrigerant in the flat tubes to exchange heat with the air flow that passes through heat exchange spaces formed by adjacent flat tubes and adjacent heat transfer fins when viewed from the first direction. The heat transfer fins each have a heat transfer fin front side surface that is one main surface, a heat transfer fin back side surface that is the other main surface.

Claim (Index 1):
A heat exchanger comprising:\n multiple flat tubes that extend in a second direction intersecting a first direction that is an air flow direction and that are disposed at intervals in a third direction that intersects the first direction and the second direction; and multiple plate-like heat transfer fins that extend along the third direction and that are disposed at intervals along the second direction, wherein the heat exchanger causes refrigerant in the flat tubes to exchange heat with the air flow that passes through heat exchange spaces formed by adjacent flat tubes and adjacent heat transfer fins when viewed from the first direction, the heat transfer fins each have a heat transfer fin front side surface that is one main surface, a heat transfer fin back side surface that is the other main surface, and a plurality of protrusions that are bulging portions or cut and raised portions that protrude along the second direction from the heat transfer fin front side surface or the heat transfer fin back side surface, the plurality of protrusions are disposed in the first direction in each of the heat exchange spaces, and the plurality of protrusion include leeward side protrusions located on the leeward side and windward side protrusions located further to the windward side than the leeward side protrusions, according to an air flow directional view from the windward side to the leeward side of the first direction, in each of the heat exchange spaces, a one-side-protrusion is one of either the windward side protrusion and the leeward side protrusion, the one-side protrusion protrudes from either the heat transfer fin front side surface or the heat transfer fin back side surface, a ratio of an area of an other-side-protrusion, which is the other of the windward side protrusion or the leeward side protrusion, that occupies a reference area is equal to or greater than 0.2, the reference area is a quadrilateral with a lateral side and a longitudinal side, where one of either the lateral side and the longitudinal side is defined by a length between an one-side-protrusion's edge, which is disposed in the heat transfer fin front side surface or the heat transfer fin back side surface that the one-side-protrusion protrudes from, and a main surface of the flat tube closest to the one-side-protrusion's edge, and the other of the lateral side and the longitudinal side is defined by a fin pitch of the heat transfer fins.
