A heat exchanger includes: a water-repellent coating film on part of a surface of the heat exchanger. The surface on which the water-repellent coating film is disposed includes a surface structure including protrusions. D/L<0.36, D/L>0.4×(L/H), D<200, L−D<1000, H>700, 0>1.28×D×10+2.77 ×(L−D)×10−1.1×D×10−5.3×(L−D)×10−9.8×D×(L−D)×10−2.0, and 90°<θ<120°, where L is an average pitch of the protrusions in nm, D is an average diameter of the protrusions in nm, H is an average height of the protrusions in nm, and θ is a contact angle of water on a smooth plane of the water-repellent coating film.

Heat exchanger, method for manufacturing heat exchanger, and refrigerant cycle apparatus

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.

Heat exchanger

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.

Heat exchanger and air conditioner

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.

Heat exchanger with air flow passage for exchanging heat

A television receiver segments a part of an image depending on image information received from a communication device and pixel information representing the number of pixels in a longitudinal direction and a lateral direction of the image. The television receiver judges a size between the number of pixels in the longitudinal direction and that in the lateral direction in the pixel information, and when it is judged that the number of pixels in the longitudinal direction is larger than that in the lateral direction, displays two screens in which the segmented image and another image are juxtaposed on a display unit. Meanwhile, when it is judged that the number of pixels in the longitudinal direction is not larger than that in the lateral direction, the television receiver receives a signal designating the number of screens to be displayed on the display unit and displays the two screens in which the segmented image and another image are juxtaposed or one screen of the segmented image on the display unit depending on the received signal.

A source device such as a mobile phone terminal can provide more surely a user with a notification of a status of the source device. A mobile phone terminal () serving as the source device includes a command processing section () which issues a command which (A) has an event ID which designates a status of the source device and (B) causes a TV () to display the status of the source device.
