Disclosed is a refrigerator provided with a sealed drawer on a door body. The refrigerator comprises: a refrigerator body, which defines a first storage space; a first door, which is pivotally arranged at a front portion of the refrigerator body and configured to open or close the first storage space; a sealed barrel, which is arranged in the first door and forms an opening at the side away from the first storage space; a drawable box arranged in the sealed barrel in a drawable manner via the opening; and a ventilating device, which is arranged in the sealed barrel and configured to allow communication between an internal space of the sealed barrel and the first storage space when turned on, thus realizing air exchange between the internal space of the sealed barrel and the first storage space.

A dilution refrigerator is provided. The dilution refrigerator includes an outer vacuum chamber comprising at least one substantially planar surface and an opening in the at least one substantially planar surface configured to provide access to an interior of the outer vacuum chamber.

A dilution refrigerator is provided. The dilution refrigerator includes a first thermal stage configured to be cooled to a first temperature, a second thermal stage configured to be cooled to a second temperature lower than the first temperature, and a vacuum chamber housing the first thermal stage and the second thermal stage. The dilution refrigerator also includes a first suspension system configured to suspend the first thermal stage from the vacuum chamber, and a second suspension system configured to suspend the second thermal stage from the vacuum chamber independently from the first thermal stage.

A distributed refrigeration system is provided. The distributed refrigeration system comprises a pre-cooling system configured to be thermally coupled to two or more cryogenic devices and to provide a first cooling stage to the two or more cryogenic devices. The two or more cryogenic devices may be two or more of a dilution refrigerator, a low-temperature microscopy system, a .sup.3He refrigeration system, and/or a superconducting CMOS system.

A dilution refrigerator is provided. The dilution refrigerator includes a plurality of thermal stages configured to be cooled to a plurality of temperatures. A coldest thermal stage of the plurality of thermal stages is disposed above warmer thermal stages of the plurality of thermal stages such that the coldest thermal stage is positioned furthest from a floor supporting the dilution refrigerator.

The invention relates to a drawer device comprising a drawer body, a drawer which can be moved linearly therein, and a cover which can be moved relative to the drawer and relative to the drawer body in a lifting direction by means of lifting means such that a controlled relative movement of the cover can be carried out in the lifting direction by means of the lifting means and a controller and such that the drawer interior can be evacuated and/or dehumidified after the cover is brought into the closed position, said drawer device allowing a reliable and reproducible movement of the cover in the lifting direction. This is achieved in that the lifting means are arranged so as to run along two lateral edges of the cover, each lifting means having a motor, a spindle, and at least one linear carriage, which is connected to the spindle and can thereby be moved linearly, in a fixed manner to the cover, wherein a profiled lifting section which is operatively connected to securing means on the drawer body can be moved by the lifting means in the lifting direction relative to the cover in a controlled manner by means of a controller relative to the rest of the lifting means and the cover.

A sound-insulating refrigerator vacuum assembly, comprising a sealed box receiving a vacuum pump, the sealed box body comprises an upper sealing body and a lower sealing body, the upper sealing body and the lower sealing body can be snap-fitted to define a receiving cavity, and the vacuum pump is placed in the receiving cavity; the vacuum assembly further comprises an air pipe member, the air pipe member comprises an air inlet pipe, an air outlet pipe and a base plate that are integrally formed, and the air inlet pipe and the air outlet pipe are disposed through the base plate; a notch portion is provided in the sealed box, and an outer edge of the base plate matches the notch portion in shape; the vacuum pump is connected with a muffler.

The present disclosure provides a refrigerator, including a storage compartment and a door opening or closing the storage compartment. A vacuum sealing device is disposed on the door. The vacuum sealing device includes an upper support and a lower support opposite to each other and a vacuumization assembly. The lower support is detachably connected to the door; opening cavities are formed on mutually-opposed surfaces of the upper support and/or the lower support; the upper support can move close to or away from the lower support under the drive of a driving device; the upper supports moves close to the lower support until the upper support and the lower support are butt-joined, and the opening cavities sealingly form a vacuumization region by sealing portions; the vacuumization assembly is in communication with the vacuumization region through a pipe to perform vacuumization or depressurization for the vaccumization region.
