A refrigeration appliance includes a freezer compartment for storing food items. An ice maker is disposed within the freezer compartment and includes a removable ice bin having an internal cavity. A front cover closes a front open end of the ice bin. The front cover includes a front face oriented toward a front of the freezer compartment, a rear face, and a recess formed in the rear face. The rear face of the front cover is disposed adjacent to a horizontal edge portion of the ice maker when the removable ice bin is disposed within the ice maker wherein the recess defines a gap between the front cover and the horizontal edge portion that fluidly communicates with the internal cavity of the removable ice bin. A plurality of ribs is disposed within the gap for directing air exiting the internal cavity of the removable ice bin into a predetermined direction.

An ice piece making assembly and a refrigeration appliance containing the ice piece making assembly is disclosed. The ice making assembly produces ice pieces by directional freezing and includes: an ice piece forming tray having a motor engaging end, a distal end, a first side, a second side and a bottom surface, a plurality of ice piece making compartments divided by divider walls, and a plurality of heat sinks engaged to the bottom surface of the ice making compartments and deliver defrost water to a drain or defrost water catch tray positioned at at least one of the distal end and the motor engaging end; and an ice piece forming tray canopy spaced a distance above the ice piece forming tray wherein the ice piece forming tray canopy comprises a heater and a temperature sensor.

A cooling device, particularly a domestic refrigerator, includes a storage space defined by a body and by a door. An air channel is formed within a space that is at least partially filled with insulating or isolation material between an inner wall of the storage space and an outer wall of the cooling device. At least one opening is provided in the inner wall and is open to the air channel. A baffle is positioned completely within the air channel.

An ice-making device for a refrigerator including a duct providing a cold air flow path under an ice tray in which water turns into ice pieces. Uneven portions extending in a direction differing from a flow direction of cold air are formed at a lower surface of the ice tray. The duct may have a wavy surface. The surface features of the ice tray and the duct can advantageously increase contact area and contact time between cold air and the ice tray, thereby increasing the heat exchange efficiency between cold air and water contained in the ice tray.

A temperature-controlled vending machine able to apply a required temperature uniformly within itself includes a cabinet and a temperature control system fixed at the bottom of the cabinet. The temperature control system includes a water tank, a compressor, a condenser, an evaporator defining an air outlet, and a cross-flow fan. The cross-flow fan includes a plurality of fan blades opposite to the air outlet and a housing defining an air guiding exit. The cross-flow fan is able to circulate cool air expelled from the evaporator from the bottom of the cabinet to the top of the cabinet.

A refrigerator including a buffer unit for restrict heat transfer between a defrosting heater and an ice maker on the refrigerator. The defrosting heater is disposed at the evaporator and can remove frost on the evaporator. A cold air duct guides cold air generated by the evaporator to the ice maker during the cooling process. A cold air supply passageway is disposed below an ice making tray inside the ice maker. The buffer unit is coupled between the cold air duct and the cold air supply passageway. The buffer unit has a curved up inner surface which facilitates formation of a heat vortex therein, thereby effectively restricting heat transfer from the cold air duct to the ice maker during the defrosting process.

A new and improved air return bulkhead for a refrigeration cargo trailer is disclosed. The air return bulkhead comprises two primary components, a first upper panel component and a second lower panel component. The first upper panel component effectively defines a fluid conduit through which relatively warm return air is fluidically conducted into the refrigeration unit, while the second lower panel component comprises a structure upon which only a plurality of pallet stops are integrally formed. The second lower panel component is entirely separate from the upper panel component, and in this manner, whenever the pallet stops become damaged, only the used lower component needs to be simply detached and replaced. An upper edge portion of the first upper panel component is also provided with a blade member which will engage the rear face of the refrigeration unit along a linear locus extending across the entire horizontal extent or width of the refrigeration unit so that cooled or refrigerated air cannot effectively be sucked back into the inlet or intake portion of the refrigeration unit, thereby preventing the occurrence of “short cycling” of the refrigeration unit.

An evaporator air duct panel (54) for a refrigeration system having an evaporator (18) and an evaporator air duct (40) at least partially defined by the evaporator air duct panel (54) is provided. The evaporator panel (54) includes a plurality of standoffs (60) extending from the evaporator air duct panel (54), the plurality of standoffs (60) configured to extend into the evaporator air duct (40).

A blast cell system is provided with simple and scalable designs that prevent short cycling of air flow through any pallets in blast cells. The blast cell includes a plurality of suction channels that provide independent fluid pathways for directing the air drawn from different rows in the blast cell into the fan.

A temperature controlled case includes a number of shelves, an air-curtain, and a number of air-straighteners. The number of shelves individually support a displayed product. The number of shelves are mounted to the temperature controlled case. The air-curtain originates at an air-curtain discharge and terminates an air-curtain return. The number of air-straighteners is equal to the number of shelves. The number of air straighteners individually include a flow guide and are individually coupled to one of the number of shelves. The flow guides are located at locations within the air-curtain. The flow guides are configured to control the air-curtain. The flow guides individually include a luminaire comprising a number of LEDs coupled to a number of PCBs. The luminaires are configured to illuminate a number of illumination targets. The number of illumination targets correspond to at least one of the displayed products.
