Abstract
Provided is an air heat exchanger capable of preventing an increase in ventilation resistance and a decrease in heat exchange efficiency due to condensation water generated on surfaces of heat transfer fins, without increasing thermal resistance of flat tubes and the heat transfer fins, and preventing scattering of water droplets downwind from the heat transfer fins. In the air heat exchanger including a plurality of flat tubesand heat transfer finsprovided between the flat tubesand on which air is blown, the flat tubesinclude water draining grooveson side surfaces on which the heat transfer finsare provided and the heat transfer finsinclude water guiding groovescommunicating with the water draining grooves. At least a groove wallon the upwind side of an air blowing directionamong groove walls forming the water guiding groovesis provided from a position of the upwind side from the water draining groovesto the water draining grooves. The water guiding groovesextend toward the water draining groovesalong the groove wallon the upwind side and an area of a cross section perpendicular to an extension direction decreases toward the water draining grooves
