Abstract: An ice bank of an ice-making device for a refrigerator is disclosed, for smooth crush and discharge of ice, which includes a housing for storing ice made in an icemaker, and provided rotatably to apply the power to the stored ice at a rotation direction; an ice discharger having at least one hole through which the ice is discharge to the external; a crusher provided in the inside of the housing, the crusher guiding the stored ice to the hole of the ice discharge and crushing the ice as a predetermined size before discharging the ice to the hole according to a user's select; and rotating means for rotating the housing. Also, the crusher includes fixed crushing means fixed to the inside of the housing, and rotation crushing means rotated for being synchronized with the housing so as to crush the ice before discharging the ice to the external according to a user's select.

Abstract: Disclosed is a refrigerator with an improved structure for supplying ices at an outside of a dispenser provided at a door. The refrigerator includes a supplementary freezer, a cavity, an icemaker and a dispenser. The supplementary freezer is provided in a cooling chamber of the refrigerator. The cavity is provided in the door and is connected with the supplementary freezer when the door is closed. The icemaker produces ices using cool air in the cooling chamber. The dispenser is connected with the cavity provided at the door. In this case, the icemaker is provided in the supplementary freezer or in the cavity.

Abstract: An icemaker for an ice supply system for preventing water from overflowing from the ice tray by vibration and/or shaking of the surrounding structure includes an icemaker, a container provided at a lower part of the icemaker and an ice chute for supplying the ice stored in the ice container. An ejector in the ice tray of the icemaker and a dropper device having an inclined upper surface at a side of the open top of the ice tray are provided for dropping the ice discharged upwardly by the ejector. An overflow prevention device is provided at another side of the open top of the ice tray for preventing water filled in the ice tray from overflowing. The overflow prevention device includes a panel extending upward from the ice tray and a cover coupled with the hinge at the top of the ice tray.

Abstract: Quick cooling device is disclosed for quick cooling of canned or bottled drink from a room temperature, quickly. A case has an inside space divided into a cavity and a device chamber, a door is provided on a front part of the case for opening/closing the cavity. Means for bringing a cold accumulation pack into contact with a drink container, and shaking the cold accumulation pack and the drink container together, to cool down drink in the container quickly is provided in the cavity. A refrigerating system is provided in the case for cooling the cold accumulation pack.

Abstract: A micro-multi channel heat exchanger includes a lower header having a hollow for receiving refrigerant and an upper header opposite to the lower header. A plurality of tubes are arranged in a length direction of the upper and lower headers at fixed intervals, each having opposite ends fixed to the upper header and the lower header. A plurality of channels are formed in the tubes and elongated to be in communication with the hollows of the two headers. Each channel has an area of a section, parallel to a length direction of the two headers, reducing at a fixed ratio as the channels go from an air inlet side to an air outlet side. A plurality of fins are located between the tubes for heat exchange with the air.

Abstract: The present invention relates to a refrigerated cooling apparatus for cooling heat generated from a semiconductor device by forming a circulating flow path of the air in a case with an evaporator and the semiconductor mounted.

Abstract: A heat exchanger with small-diameter refrigerant tubes is disclosed. The heat exchanger has a plurality of air guide fins assembled with each other by one or more vertical rows of refrigerant tubes passing through the air guide fins. In the heat exchanger, each of the refrigerant tubes is a small-diameter tube having an outer diameter of not larger than 6 mm. In addition, four rows of offset surfaces are vertically formed on each of the air guide fins at a position between two tubes of each vertical row of refrigerant tubes through a pressing process such that the four rows of offset surfaces are arranged along a transverse direction of the fin. Four rows of vertical slits are each formed by two air guide openings defined between opposite side edges of each of the offset surfaces and the land surface of the air guide fin.

Abstract: A refrigerant tube for heat exchangers is disclosed. The refrigerant tube has an outer diameter of not larger than 5.3 mm, with a plurality of internal spiral fins formed on the inner surface of the refrigerant tube. The refrigerant tube has a thickness of 0.16 mm˜0.2 mm. The internal spiral fins are set in their number to 40˜50, and each have a height of 0.15 mm˜0.18 mm, a projection angle of 38°˜42°, and a spiral angle of 6°˜20°. Due to the internal spiral fins in addition to the reduced outer diameter of the refrigerant tube, the tube reduces the production cost of heat exchangers and accomplishes the recent trend of compactness of the heat exchangers. The tube also has several advantages expected from small-diameter refrigerant tubes, such as a reduction in air-side pressure loss, and improves heat transfer efficiency of the heat exchangers. This refrigerant tube thus enhances the heat exchange operational performance of the heat exchangers.
