Abstract:
To provide a refrigerator in which sufficient heat exchange performance of a heat exchanger can be obtained even in an environment with a small amount of air from a cooling fan.SOLUTION: A refrigerator 1 includes: heat exchangers 8, 12 having a flat pipe 20 where a plurality of flow passages 20a through which refrigerant flows are formed, an inlet side header 21 provided on the inlet side of the flat pipe 20, and an outlet side header 22 provided on the outlet side thereof; and a cooling fan 9 cooling the heat exchanger. In the heat exchangers 8, 12, corrugated fins 23 are reduced in a range where heat exchange performance in driving the cooling fan 9 at rotation frequency the same as that of a standard type heat exchanger is equal to or higher than standard performance when the heat exchange performance of the standard type heat exchanger 100 where the corrugated fins 23 are provided entirely on the surface of the flat pipe 20, is defined as the standard performance, or any of corrugated fins 23 are not provided.SELECTED DRAWING: Figure 6
