In the present embodiment, the cross sections of the temperature equalizing air duct 31 and the fan housing 42 are square, and the first air openings 311 are disposed on four sides of the temperature equalizing air duct 31 and face four side walls 122 of the refrigeration compartment 121. The bottom case 423 of the blower case 42 is formed with four case air outlets 4231 at four corners to discharge air out of the blower case 42.
