An ice cube for use in a water pipe with an ice catch may present a plurality of bores formed within the bulk of the ice cube. These bores will then allow smoke from a smokable substance to pass through the bulk of the ice cube and enhance the cooling effect of the ice cube on the smoke. The bores may be interconnected by one or more tranches at a bottom surface of the ice cube such that fluid communication is maintained between the bores, in the event the bottom of the ice cube is partially impinged upon by another ice cube or other obstruction. A mold for making such a cube may be accomplished by having a plurality of rods extend from a bottom of the mold and providing appropriate ridges to form the trenches.

An ice maker for fitting into a cooling or freezing appliance includes an ice-making tray which forms a plurality of ice-piece-producing cavities for producing one ice piece each. An air channel is formed above the ice-making tray, which serves to guide a cold air stream. There is provided a heat-dissipating structure including a metal material and having a plurality of heat-dissipating pins, each of which, in a freezing phase, projects from above, with a pin tip leading, into one of the ice-piece-producing cavities. In some embodiments, the heat-dissipating pins extend into and through the upper air channel, so that the cold air flowing in the air channel flows around shaft portions of the heat-dissipating pins situated inside the air channel. When the ice-piece-producing cavities are filled with water, the heat-dissipating pins immersed in the water ensure improved dissipation of thermal energy from the water, which accelerates freezing.

A refrigerator having an ice-making device evaporator in addition to a refrigerator storage room evaporator. The ice-making device includes an ice tray and a cooling pipe contacting an outer surface of the ice tray. A refrigerant flows in the cooling pipe and directly cools the ice tray. The ice-making device evaporator receives the refrigerant from a condenser and supplies it to the cooling pipe. A heat insulation member wraps around the cooling pipe and can prevent the cooling pipe from exchanging heat with ambient air.

Embodiments of the present invention are generally directed towards apparatuses for producing ice cubes. In particular, embodiments of the present invention are directed to trays for making ice cubes in a manner that allows for ice to be produced with a clear or semi-clear transparency through the elimination of gaseous water during the freezing process.

Embodiments of the present invention disclose an ice-making device including an ice tray configured to make ice pieces from water, an ice-making duct, a scroll fan unit, and a cold air guide. The ice-making duct is configured to receive a cold air and supply the cold air toward a lower portion of the ice tray. The scroll fan unit is installed under the ice tray and configured to transfer the cold air supplied from the ice-making duct. The cold air guide is provided under the ice tray and configured to guide the cold air so that the cold air transferred by the scroll fan unit is uniformly supplied to a lower portion of the ice tray.

An ice maker includes a harvest motor and an ice tray operably coupled to the harvest motor. The ice tray has a plurality of heat sinks coupled to a bottom section of ice forming cavities on the ice tray. The harvest motor is operable to twist the ice tray for causing the plurality of heat sinks to move relative to each other for releasing ice pieces from the ice forming cavities.

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.
