Abstract
A heat exchanger is disclosed including a plurality of plate fins which are disposed in parallel at a predetermined interval and between which air flows; heat transfer tubes through which fluid runs; and a plurality of strips formed on the fins between nearby heat transfer tubes, the strips being divided into first strips formed on a center line connecting the centers of the nearby heat transfer tubes, and second strips opposingly disposed centering on the center line and formed along an ellipse having the center line in the direction of the line of apsides.
Claims3
A heat exchanger comprising:
- a plurality of plate fins which are disposed in parallel at a predetermined interval and between which air flows;
- heat transfer tubes extending perpendicularly through said plate fins;
- a plurality of strips cut from the fins between nearby heat transfer tubes, each of said strips having a pair of opposed erect portions, said strips being divided into first strips cut from a center line connecting centers of the nearby heat transfer tubes;
- and
- second strips opposingly disposed centering on the center line and formed along an ellipse having the center line in the direction of a line of apsides, the erect portions of said second strips having an inclination angle which is equal to an angle of a tangent line of a concentric circle of the heat transfer tube circumscribed with the erect portions,
- said first and second strips are segmented and said strips are divided along an arc having a common center as the heat transfer tubes, respectively.
