Claims

[Scope of utility model registration request]

Air cooling cools the air by heat exchange between the refrigerant and the air passing horizontally along both side planes of the flat tube, which has a refrigerant passage formed inside and extends vertically. An air cooler characterized in that grooves are formed in the vertical direction on the both side surfaces of the flat tube to guide water droplets adhering to the both side surfaces due to the heat exchange downward.
