HEAT EXCHANGER

摘要

A heat exchanger is provided to form a flat bottom part to each bottom point part of W-shaped corrugate fins, thereby increasing an air passing area among the fins for a high flow rate of air among tubes. A heat exchanger includes a plurality of fins(110) formed with top and bottom point parts of same height continuously, and a plurality of tubes(30) mounted to the fins. The bottom point parts of the fins have a flat bottom part(114) by a predetermined width(W), so that an air passing area among the fins is increased and air flowing among the tubes may advance to rear parts of the tubes effectively.
