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.

Heat exchanger

Disclosed is a heat exchanger including: a plurality of tubes through which refrigerants flow, the tubes being spaced away from one another; and a fin through which the tubes are perpendicularly inserted, and having a fin collar for supporting the inserted tube, a seat for supporting an outer circumference of a lower end of the fin collar, and three or more peak portions and three or more valley portions that are alternately disposed at an area defined between the tubes to cause air flow to vary at an area defined between the fin collar, heights of at least two peak portions or depths of at least two valley portions being different from each other.

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.
