An air blower includes: a panel (); a frame member () arranged to surround the panel () and having a blowout port () of air formed therein; and a fan () that sends air to the blowout port (). The frame member () produces airflows that are blown out from at least three directions and collide with each other, thereby producing an air current going forward to the panel ().

Air blower

An air-blowing apparatus includes a main body and a fan. In the main body a blow-out region is formed. The fan is provided in the main body and sends air toward the blow-out region. The air-blowing apparatus blows out air from the blow-out region such that a ratio (Vmax/Vmin) of a maximum value Vmax of wind velocity to a minimum value Vmin of the wind velocity is 1 or more and 10 or less in a target virtual plane. The target virtual plane is a virtual plane that faces the blow-out region. As a result, comfort of a person exposed to the wind sent from the air-blowing apparatus is improved.

Air blowing apparatus and air conditioner

An air-cooled and ventilated heat exchanger includes a fin and a plurality of heat transfer tubes. The fin has a plate-shaped part and a plurality of protruding parts. The plate-shaped part is positioned so that a plate-thickness direction intersects an air-flow direction generated by ventilation, and the protruding parts protrude from the plate-shaped part in the plate-thickness direction. The heat-transfer tubes are-inserted into the fin so as to intersect the air-flow direction. The protruding parts have a first protruding part and a second protruding part. An inclination angle of the first protruding part with respect to the plate-shaped part is a first angle, an inclination angle of the second protruding part with respect to the plate-shaped part is a second angle, and the second angle is different from the first angle. The second protruding part is placed adjacent to the first protruding part.
