HEAT EXCHANGER

摘要

A heat exchanger is provided to collect and drain condensed water from surfaces of fins without scattering by forming collecting and draining paths with protrusion parts. A heat exchanger includes tubes(2) through which refrigerant flows. A plurality of fins are fitted with the tubes, and have a plurality of draining paths(11-14) extended in a direction and a plurality of collecting paths(21-23) connected to the drain paths at least at an end of each with inclination for collecting condensed water from the fins and guiding the collected condensed water to the drain paths. A plurality of protrusion parts(4) are formed upward from the fins for preventing scattering of the condensed water flowing through the drain and collecting paths.
