Abstract

A fan module is provided. The fan module is configured to dissipate heat from, e.g., a compressor and a condenser disposed in a machine room of the refrigerator. The fan module includes a fan, a shroud having a receiving hole positioned around the fan, a fan mounting portion coupled to a rear surface of the shroud on which the fan is mounted, the rear surface facing a downstream airflow direction of the fan, and a concave recess provided on a rear surface of the shroud and circling the receiving hole. The fan module prevents noise caused by air passing through the receiving hole and prevents flow loss.

Description

[0001] This application claims priority from Korean Application No. 10-2007-0136865 filed in Korea on December 24, 2007, the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to a fan module, in particular to a fan module capable of cooling a compressor and a condenser arranged in a machine room of a refrigerator. Background technique [0003] Refrigerators are generally used to store food in a frozen state or a refrigerated state using a low temperature according to the type of food to be stored. [0004] When the refrigerant performs a heat exchange operation, cool air supplied into the refrigerator is generated, and when the refrigerant repeatedly performs cycle operations such as compression-condensation-expansion-evaporation, the cool air is continuously supplied into the refrigerator. The cold air is uniformly delivered to the inside of the refrigerator by convection, and is used to preserve food in th...
