Abstract

A refrigerator shroud is provided to reduce a power consumption and temperature deviation of a storing chamber for realizing uniform cooling of the storing chamber entirely. A refrigerator shroud includes a fan guide(62) surrounding a fan(52) with a predetermined distance for guiding chilled air flow around the fan. A distribution guide(66) defines chilled air paths around the fan for guiding the chilled air flow of the chilled air paths, wherein the distribution guide defines the chilled air paths toward the fan and the fan guide. One or more outlet paths are connected to the chilled air paths partially for transmitting the distributed chilled air partially to discharge. The outlet paths are an upper outlet path connected to the fan guide for discharging the chilled air to an upper part of a refrigerator, and a lower outlet path(61) connected to the fan guide for guiding the chilled air to a lower part of the refrigerator.
