Superconducting bulk cooling apparatus and cooling method for high-temperature superconducting magnetic levitation vehicle
The present invention discloses a superconducting bulk cooling apparatus and cooling method for a high-temperature superconducting magnetic levitation vehicle. The superconducting bulk cooling apparatus for the high-temperature superconducting magnetic levitation vehicle includes a refrigerating machine, a vacuum box and a Dewar tank. A condensing tank is arranged in the vacuum box, and the condensing tank is communicated with the Dewar tank through a nitrogen siphon pipe and a liquid nitrogen return pipe; a heat exchanger connected with the refrigerating machine is arranged in the condensing tank; and a flexible isolation pipe for thermally insulating and isolating the nitrogen siphon pipe and the liquid nitrogen return pipe is connected between the vacuum box and the Dewar tank. The present invention pumps the phase-change nitrogen out of the Dewar tank through a siphoning effect, so that the immersion cooling of high-temperature superconducting bulks is separated from the re-condensation of the nitrogen.
Refrigerated Post-Mix Dispenser
A post-mix beverage dispenser having all components within an insulated housing is provided. The beverage dispenser can include an insulated housing with interior compartments that contain all complementary for dispensing a beverage, a carbonated beverage, and ice. The interior compartments can contain a concentrate source, a concentrate pump, an ice bin, an ice dispensing mechanism, a refrigeration system, a diluent pump, and a carbonation system.
REMOTE COOLING OF SUPER-CONDUCTING MAGNET USING CLOSED CYCLE AUXILIARY FLOW CIRCUIT IN A CRYOGENIC COOLING SYSTEM
A remote cooling system of super-conducting magnets uses a closed cycle auxiliary flow circuit in a cryogenic cooling system. The super-conducting magnet is connected to the cryogenic cooling system via a flexible interface. This flexible interface has a rigid insert on its distal end and may be connected to a cryostat on its proximal side. The rigid end may be inserted in a mating cryogenic interface at the super-conducting magnet. The closed cycle auxiliary flow circuit allows the cryogenic cooled magnet to operate at its designed magnetic field strength and can keep the magnet operational at cryogenic temperatures for extended periods of time since no cryogenic fluid needs to be replenished. Such a system can have test samples raised to room temperature to make sample changes without any need to warm up the magnet. This makes sample change time and experiment turnaround time significantly shorter, and significantly increases productivity.

A COOLING ARRANGEMENT FOR A SUPERCONDUCTING MAGNET STRUCTURE FOR AN MRI SYSTEM
A superconducting magnet structure comprising a number of axially aligned superconducting inner magnet coils (34) making up an inner magnet structure (30) and a number of superconducting outer coils (32) each having an inner diameter greater than an outer diameter of each of the inner magnet coils (34). The inner magnet structure is enclosed within a cryogen vessel (12), and the outer coils are located outside of the cryogen vessel, in thermal contact with a cooling arrangement (36, 38) for cooling the outer coils.
Refrigerator and vacuum heat insulating material for use in refrigerator
The present invention provides a refrigerator with improved refrigerator box strength and high heat insulating performance, which is configured such that external deformation due to entry of air into a vacuum heat insulating material, the entry of air being caused by aging degradation, is prevented. The present invention includes: a heat-insulated box including an inner casing and an outer casing, in which space between the inner casing and the outer casing is filled with a foamed heat insulating material; and a vacuum heat insulating material disposed in at least a side wall of the heat-insulated box together with the foamed heat insulating material, the vacuum heat insulating material including an outer skin material, the outer skin material including at least a core material and being decompression-sealed. The vacuum heat insulating material includes a gas adsorbent. Since the vacuum heat insulating material including the gas adsorbent is included in the side wall, which tends to be greatly distorted among the heat insulating walls of the refrigerator, the rigidity of the side wall is improved and aging degradation of the vacuum heat insulating material is suppressed. As a result, the rigidity of the heat-insulated box can be maintained for a long term, and external deformation of the outer casing of the body can be prevented.
TEMPERATURE-CONTROLLED VENDING MACHINE
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.
Container refrigeration apparatus
Left and right edge portions of an external casing of a container refrigeration apparatus each include a column member that is continuous from the upper end to the lower end of a casing. Left and right edge portions of an internal casing each include a side plate that is continuous from the upper end to the lower end of the casing. The column members of the external casing and the associated side plates of the internal casing are fixed together, thereby increasing the strength of the casing including the external casing and the internal casing.
