Provided is a refrigerator including a cabinet forming one of a refrigerator compartment and a freezer compartment, a main door opening and closing the refrigerator compartment or the freezer compartment and including a storage space opened forward, a sub door installed on the main door and opening and closing the storage space of the main door, and a dispenser disposed on the sub door and dispensing water.

The present invention provides a cold end heat exchanging device, which comprises: a cold end heat exchanging part which defines an inner cavity or pipeline for containing a refrigerant existing in both gas and liquid phases; and a plurality of refrigerant pipelines, each provided with: an evaporation section which is downwardly bent and extends in a vertical plane and has a closed tail end, and a connection section which is upwardly bent and extends from a starting end of the evaporation section and is connected to the inner cavity or pipeline; wherein the evaporation sections of at least some refrigerant pipelines are arranged in two vertical planes perpendicular to each other. The present invention further provides a semiconductor refrigerator having the cold end heat exchanging device. The cold dissipation efficiency of the cold end heat exchanging device and the energy efficiency of the semiconductor refrigerator are significantly improved.

A sintered heat tube and a semiconductor cooling refrigerator having the same, the sintered heat tube comprises: a main tube segment with its both ends closed, and a manifold tube segment/manifold tube segments extending from one or more portions of one side of the main tube segment (respectively), wherein a work chamber of each manifold tube segment communicates with that of the main tube segment. In the sintered heat tube and the semiconductor cooling refrigerator having the sintered heat tube of the present invention, as the sintered heat tube includes manifold tube segments, the sintered heat tube of the present invention greatly improves the heat radiating or cold transferring efficiency. The sintered heat tube is particularly suitable for heat radiation of heat sources of a high heat flow density such as semiconductor cooling plates.

A storage basket used for storing and displaying food products and packages in a refrigerator or freezer unit may include a single-material first portion including a bottom wall and an upright wall that extends away from the bottom wall. The bottom wall and the upright wall are imperforate, thereby creating a solid barrier to transfer and fall-through of materials contained in the storage basket. The storage basket may also include a single-material second portion coupled to and extending from the upright wall, and the second portion may include a plurality of perforations. The plurality of perforations may permit airflow around and about the materials contained in the storage basket.

A modular refrigeration assembly includes a plurality of refrigerators and each of the refrigerators may contain perishable items. A selected number of the refrigerators are removably coupled together. Thus, the selected refrigerators may facilitate a selected amount of cold storage area. The selected refrigerators are selectively uncoupled from each other. Thus, the selected refrigerators may be moved through an area that has a height and a width that is less than a height and a width of the selected refrigerators when the selected refrigerators are removably coupled together.

A humidifier cools air in an air path that supplies the air to an internal space of a storage chamber such as a container or a warehouse, extracts water in a water extracting unit, stores the extracted water in a humidifying unit, and humidifies the internal space. The air path includes a main path that communicates with the internal space and a discharge path that discharges a part or all of water-extraction air to the outside of the target space, so that the humidifier can sufficiently humidify the internal space without receiving supply of water.
