<p>A centrifugal fan for a refrigerator with a plurality of vanes (62) arranged radially about a central a shaft (72); a ring-shaped shroud (64) coupled to the vanes (62) and having a curved portion (64a) with a predetermined radius or curvature and also having an angled portion (64b) with a predetermined gradient or angle relative to the curved portion (64a); and a bottom surface (66) coupled to the vanes (62) on the side opposite the shroud (64); where a ratio (r/R) of an inner diameter r, which is the shortest distance between the vane (62) and the shaft (72), and an outer diameter R, which is the longest distance between the vane (62) and the shaft (72), is approximately 0.69 ± 0.01.</p> |
