A refrigerator appliance includes a rear wall, side walls, a bottom wall, and partitions. The side walls are secured to and extend from the rear wall toward a front side of the refrigerator. The bottom wall is secured to the side walls along a bottom end of the rear wall. The side walls and the bottom wall define a cavity below the bottom wall and define an opening to the cavity along the front side of the refrigerator. The rear wall and the bottom wall define a machine compartment. An exterior surface of the rear wall defines an inlet to and an outlet from the machine compartment. A first partition extends outward from the exterior surface and is disposed between the inlet and the outlet. A second partition extends from a bottom of the first partition. The partitions are configured to segregate airflows between the inlet and outlet.

Coolers with airflow management systems are disclosed. The coolers include a cabinet that has a door with a transparent section. A refrigeration unit is coupled to the cabinet. The refrigeration unit has an airflow inlet and an airflow outlet. The cross sectional area of the airflow outlet is less than the cross sectional area of the airflow inlet. The refrigeration unit is fluidly coupled to an airflow management system that is in fluid communication with the airflow outlet. The airflow management system includes discharge vents and turbulence reduction vents.

The present invention discloses a refrigerator, comprising a compressor compartment disposed in its lower rear portion thereof, wherein the back plate of the compressor compartment has a first air port and a second air port, and the bottom plate is provided with a third air port. The refrigerator further comprises a baffle movably disposed at the first air port to open or close the first air port. The baffle may prevent the hot air discharged from the compressor compartment from blending with cold air and re-entering the compressor compartment after the refrigerator is embedded in the cupboard.

A refrigerator includes a body, first and second storage compartments and a machine compartment formed in the body, a blower fan disposed in the machine compartment, first and second refrigerating units comprising first and second compressors to compress first and second refrigerants, respectively, first and second condensers to condense the first and second refrigerants, respectively, first and second expansion valves to expand the first and second refrigerants, respectively, and first and second evaporators to evaporate the first and second refrigerants, respectively, the first and second refrigerating units supplying cold air to the first and storage compartments, respectively. The first compressor, the second compressor, and the first condenser are disposed in the machine compartment and are cooled by forcible flow of air caused by the blower fan, and the second condenser is disposed outside the machine compartment and is cooled by natural convection of air.

The present invention discloses a recessed refrigerator supported on a supporting surface, the refrigerator including a cabinet, a door movably disposed at a front side of the cabinet, a compressor compartment formed in a rear lower portion of the refrigerator and a compressor and a heat dissipating fan located in the compressor compartment, the cabinet including a bottom plate, the bottom plate being disposed apart from the supporting surface, and the bottom plate including a compressor compartment bottom plate located below the compressor compartment, the compressor compartment bottom plate being formed with a main air inlet and a main air outlet communicating the external with the compressor compartment, air from the external, driven by the heat dissipating fan, entering the compressor compartment through the main air inlet and then flowing to the external through the main air outlet.

A refrigerator an outer case that forms an outer appearance of a cabinet in which a storage space is formed, a machine chamber provided at a lower end of a rear surface of the cabinet and independent of the storage space, the machine chamber being configured to receive a compressor and a condenser, frame assemblies provided at lower ends of both side surfaces of the outer case, and a main plate provided between the frame assemblies, the main plate forming the machine chamber, in which the frame assembly includes a reinforcement frame provided along a lower end and a rear edge of the outer case; and a reinforcement bracket coupled to the reinforcement frame and provided along circumferences of both side surfaces of the machine chamber in a left and right direction.
