A kind of low temperature cold insulation energy-saving vertical storage box
Technical field
The present invention relates to a kind of vertical storage box, particularly relate to a kind of low temperature cold insulation energy-saving vertical storage box.
Technical background
Along with the fast development of China's economic and popularizing of low temperature technique, all trades and professions constantly increase for the demand of low tempertaure storage box, its application has started to be penetrated into each department of name of the country economy, improving the people's eating patterns, quality of life, healthy and improve aspect service water equality and play an important role, obvious economic results in society have been obtained.But, traditional low temperature incubation chamber is generally used liquid nitrogen as its refrigeration source, in use consumed a large amount of refrigerant gas, there is serious energy dissipation, in addition because China's low temperature technique is at the early-stage, its application is still in the junior stage, all immature in very many-sided application, aspect standardization effort, product design, pricing practice and the trade management of low-temperature (low temperature) vessel, all has problems.
Vacuum heat-insulating plate is a kind of super heat-insulating material of researching and developing in recent years, it is the current known best thermal insulating material of heat-insulating property, its coefficient of thermal conductivity can be low to moderate 0.002W/mK, than the air low order of magnitude also, its heat-proof quality is 37 times that in common refrigerator-freezer, use 20 times of polyurethane foam plastic thermal insulation material and in building house, use glass wool thermal insulation material in addition.Compare with traditional heat preserving and insulating material, vacuum heat-insulating plate can be when meeting coefficient of thermal conductivity and reaching regulation and require, have the plurality of advantages such as adiabatic flaggy is thin, volume is little, lightweight concurrently, be highly suitable for the little refrigerator ice cabinet in warm material space, energy-conservation high external wall, the aircraft airship field that lightweight performance is good of requiring.
Application number is that 201110402989.5 Chinese invention patent discloses a kind of refrigerated storage case with two-stage fractional condensation separation regenerative formula mixed work medium for throttling refrigeration, this invention is to adopt conventional oil lubrication single-stage compressor to drive, by the method that under low temperature in refrigeration system, suitably warm area is set up one-level fractional condensation disconnector, its advantage is when guaranteeing refrigeration system high heating power efficiency, with cheap cost, effectively avoid too much higher boiling component to enter low-temperature space, realize refrigeration system not only efficiently but also reliability service, its shortcoming is to adopt fractional condensation disengagement gear, experimental facilities is too complicated, cost is too expensive, be unfavorable for that it applies on a large scale.
Application number is that 201220586346.0 Chinese invention patent discloses a kind of chamber door for deep cooling deep freezer and deep cooling deep freezer, the chamber door of this invention comprises first body and second body, between door seal retainer and doorframe retainer, be provided with high molecular polymer separator low temperature resistant, low thermal conductivity, its advantage is effectively the inside of deep cooling deep freezer to be completely cut off with outside, has reduced to a certain extent heat transmission.Its shortcoming is that this chamber door adopts Double-door body structure, and manufacturing process is comparatively complicated, although and separator can effectively completely cut off inner the and extraneous environment of deep freezer, can not keep for a long time the low temperature environment in casing, heat insulation effect is not good.
Summary of the invention
Object of the present invention is intended to overcome the deficiencies in the prior art, provides in a kind of box that temperature is lower, better heat preservation, energy consumption low temperature cold insulation energy-saving vertical storage box still less.
For realizing the technical scheme that object of the present invention adopts, be: a kind of low temperature cold insulation energy-saving vertical storage box, comprise lid, container, inner bag and ice apron, it is characterized in that being provided with heat-insulation layer in lid and shell of tank interlayer, heat-insulation layer is to consist of the very low vacuum heat-insulating plate of coefficient of thermal conductivity, its coefficient of thermal conductivity is less than 2mW/mK, and thickness is 5~200mm.Lid and container can be realized slitless connection, and heat-insulation layer that whole box body inside consists of vacuum heat-insulating plate is coated, can prevent to a great extent the heat transmission of box body between inside and outside, maintain for a long time the low temperature environment in box.
An inner bag of being made by plastics or corrosion-resistant steel of the inner placement of box body, inside face posts the aluminium foil of layer, prevent that the object of putting into from directly contacting and causing corrosion with inner bag surface, the thickness of inner bag is 0.1~0.5mm, its outer wall and shell of tank inwall keeping parallelism also leave certain space, distance is between the two 4~20mm, and this makes ice cube melt formed water afterwards can be smoothly toward dirty.Inner bag is fixed by 3~4 pillars of container bottom, prevents that in use inner bag run-off the straight from destroying container inner wall.
Ice apron is that liquid is impermeable, detouchable, during dress ice, ice apron can be laid down, in lid, pack into after enough ice cubes, ice apron is arranged on lid, form integral structure with lid, ice apron and lid inner side form V-structure, after lid and container screw, V-structure drops in the gap between inner bag and shell of tank, ice when ice apron top dissolves into after water, and water can only flow into along the bottom of V-structure in the water space between container and inner bag and can not flow in inner bag.Frozen water can effectively reduce the temperature in inner bag and maintain for a long time low temperature, plays the effect of cold insulation.
The invention has the beneficial effects as follows: (1) lid and internal tank adopt vacuum heat-insulating plate as heat-insulation layer, not only coefficient of thermal conductivity is low but also good heat insulating, can effectively stop the heat transmission between cassette interior and external environment condition, maintain for a long time low temperature in box, greatly extended the waiting time of storage box.(2) in box, place an inner bag, object is placed in its inside, rather than directly contacts with container inner wall, has effectively protected internal tank, has also avoided in addition ice cube to melt the rear water forming object is impacted.(3) adopt in box ice cube as refrigeration source, greatly controlled cost, and ice cube easily gets easily and take, easy to operate, be convenient to practical operation.
