In this embodiment, the air passing area of the air inlet 41 refers to an area of the air inlet 41 where the air can flow in and out. In this embodiment, the air-cooled refrigerator further includes a door (not shown) pivotally disposed on the refrigerator body 10, and configured to open or close the first cooling compartment 11 and the second cooling compartment 12. In this embodiment, the first refrigerating compartment 11 is a freezing compartment, and the second refrigerating compartment 12 is a refrigerating compartment or a temperature changing compartment; of course, in other embodiments of the present invention, the cabinet 10 of the air-cooled refrigerator may further define a third cooling compartment.
