摘要: A heat exchanger includes: a surface with a water-repellent coating. The surface has a surface structure that includes protrusions. Condensed water droplets, each having a droplet diameter that allows a subcooled state to be maintained even under a predetermined freezing condition, combine with one other on the surface and generate an energy. The surface structure uses the energy to remove the combined condensed water droplets from the surface.

摘要: A heat exchanger includes: refrigerant channels that extend in a first direction, are disposed along a second direction intersecting with the first direction, and are disposed along a third direction intersecting with the first direction and the second direction; and heat transfer tubes defining the refrigerant channels. One or both of a size of an outer edge and a size of an inner edge of the heat transfer tubes are different between a first position and a second position in the first direction. Outer surfaces of the heat transfer tubes each include a protrusion that protrudes in a direction intersecting with the first direction, and is in contact with an outer surface of one of the heat transfer tubes adjacent thereto in the second direction. The protrusion includes a concave portion extending along the third direction.

摘要: 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.
