Abstract
A heat exchanger includes a plurality of tubes through which refrigerants flow, the tubes being spaced apart from each other, and a plurality of fins spaced apart from each other at a predetermined distance. Each of the fins has fin collars through which the tubes are perpendicularly inserted, seat portions concentrically formed around outer circumferences of the fin collars and provided with laterally-opened front and rear portions, more than two peak portions, and more than two valley portions, the peak and valley portions being alternately disposed to provide airflow variation.
Claims20
A heat exchanger comprising:
- a plurality of tubes through which refrigerants flow, the tubes being spaced away from each other at a predetermined distance;
- and
- a plurality of corrugated fins spaced away from each other at a predetermined distance, each of the corrugated fins including:
- a plurality of peaks and a plurality of valleys alternately arranged along a first direction;
- a plurality of fin collars through which the tubes are inserted, each of the fin collars being located in between two immediately adjacent peaks along the first direction;
- a plurality of seat portions, each of the seat portions being located around an outer circumferences of the corresponding fin collars and having a first end for receiving air and a second end for discharging the air, each of the seat portions being a substantially flat area lower than a valley between the two immediately adjacent peaks.
