ENCLOSURE COMPONENT USED IN AIR COOLED REFRIGERATOR, AIR COOLED REFRIGERATOR, AND ENCLOSURE COMPONENT DESIGNING METHOD

摘要

An enclosure component used in an air cooled refrigerator comprises: an enclosure (10), a centrifugal fan (20), and a plurality of volute tongues (11). A plurality of air supply vents is formed on the enclosure (10). The centrifugal fan (20) is provided in the enclosure (10). The plurality of volute tongues (11) is provided along a circumference of the centrifugal fan (20) at intervals. A passage (12) is defined between two adjacent volute tongues (11), and the passage (12) is used to lead air blown by the centrifugal fan (20) to a corresponding air supply vent. First ends, adjacent to the center of the centrifugal fan (20), of at least some volute tongues (11) among the plurality of volute tongues (11) are located on a first volute profile (30).
