Abstract

A cool air supplying apparatus for a refrigerator is disclosed. The cool air supplying apparatus includes a freezing chamber evaporator (230) that generates cool air supplied to a freezing chamber, a refrigerating chamber evaporator (330) that generates cool air supplied to a refrigerating chamber, a freezing chamber cross flow fan (600) that blows cool air generated by the freezing chamber evaporator toward the freezing chamber, a refrigerating chamber cross flow fan (700) that blows cool air generated by the refrigerating chamber evaporator, and a driving motor (500) that drives the freezing chamber cross flow fan and the refrigerating chamber cross flow fan. With this structure, cool air introduced in the evaporators is substantially uniform, thus enhancing heat exchanging efficiency.
