Abstract
Disclosed is a heat exchanger including a plurality of tubes through which refrigerants flow, the tubes being spaced away from each other, and a plurality of fins through which the tubes are perpendicularly inserted, the fins being spaced away from each other at a predetermined distance, each of the fin having more than four peak portions and more than four valley portions that are alternately disposed. Heights or depths of at least two peak portions or at least two valley portions being different from each other.
Claims17
A heat exchanger comprising:
- a plurality of tubes through which refrigerants flow, the tubes being spaced away from each other;
- and
- a plurality of fins spaced away from each other at a predetermined distance, each of the fin including:
- a plurality of fin collars through which the tubes are perpendicularly inserted, and
- a plurality of peak and valley portions alternately disposed in a first direction at an area defined between the tubes, the peak portions and the valley portions extending along a second direction, the peak portions being non-coplanar and the valley portions being substantially coplanar, an interior angle of each of two immediately adjacent peak portions centermost to the corresponding one of the fin collars being different from an interior angle of each of the other peak portions immediately adjacent to the two immediately adjacent peak portions centermost to the corresponding one of the fin collars.
A heat exchanger comprising:
- a plurality of tubes through which refrigerants flow, the tubes being spaced away from each other;
- and
- a plurality of fins spaced away from each other at a predetermined distance, each of the fins including:
- a plurality of fin collars through which tube is perpendicularly inserted,
- a plurality of seats, each of the seats being disposed around an outer circumference of a corresponding one of the fin collars,
- a plurality of peak and valley portions alternately disposed in a first direction at an area defined between the tubes, the peak portions and the valley portions extending along a second direction, one of the valley portions being located between two immediately adjacent peak portions centermost to the corresponding one of the fin collars, and
- a plurality of inclined portions extending from an outer circumference of a corresponding one of the seats to at least two of the peak portions, each of the two of the peak portions being respectively immediately adjacent to the two immediately adjacent peak portions centermost to the corresponding one of the fin collars.
