Abstract
A motor cooling apparatus for use with the refrigerator which includes an evaporator, a condenser, a compressor and a main motor adapted to actuate the compressor and connected to the condenser at the internal space thereof. The motor cooling apparatus includes a refrigerant liquid guide passage for guiding refrigerant liquid condensed in the condenser to the internal space of the main motor by means of a refrigerant pump; a first opening formed in the condenser and connected to the internal space of the main motor; and a second opening formed at the bottom of the condenser and connected to the evaporator. The condenser has a reservoir at the bottom thereof to stock the refrigerant liquid. The reservoir is located between the first and second openings in the longitudinal direction of the condenser and connected to the refrigerant liquid guide passage on the suction side of the refrigerant pump. The reservoir may be formed at the same position as where the second opening is formed. The reservoir is provided in this case with a throttle device at the bottom thereof to control the amount of the refrigerant liquid flowing from the condenser to the evaporator. A dam is further formed in the reservoir, enclosing the throttle device, to prevent the refrigerant liquid which has flowed into the reservoir from flowing directly to the throttle device.
