Abstract

An insulating box belongs to a heating body of a daily used refrigerator, an ice chest, a low temperature box or freezing base equipment with a super-low temperature of more than 60 degrees below zero. The inner an outer layer boxes and the door are all made of environmental double-sided lamination bamboo plywood used for architecture. Plastic thin plates are adhered to the relative surfaces of the inner and outer layers boxes. The air in a sealed hollow cavity formed between the inner and outer layer boxes by supporting blocks, which support each other, is pumped out to form a vacuum-insulating layer. And with a vacuum door, an insulating box is formed. The box body is formed by docking tenons and mortises arranged on the peripheral connecting part of every face of the box with high-intensity binder for sealing. The utility model has the advantages of free anti-hygroscopy, high intensity, strong toughness, abrasion resisting, gravity bearing, strong impact resistance, high temperature resistance of 90 degrees, low temperature resistance of 60 degrees below zero, low thermal conductivity only with 0.14-0.16, acid and alkali resistance, insect bite control, simple production equipment and process and easy production. The insulation effect is six times higher than the polyurethane.

Description

The vacuum heat-preserving case

Affiliated technical field

The utility model relates to refrigeration plant, and particularly daily life is with refrigerator, refrigerator-freezer, cryogenic box, the ultralow incubator more than-60 ℃, the insulation of freezing library facilities.

Background technology

At present, the insulation of well-known refrigeration plant all is that the container body of outer cover that is made of metal and interior layer box body made of plastic constitute, inside and outside two-layer between fill insulant material reach.Insulation material is used the polyurethane blowing agent mostly, foaming forms thermal insulator, produce a large amount of pernicious gases in the foaming process, not only dirty environment, serious harm health also, metal shell thermal conductivity factor height, existing incubator all comes holding temperature by acting at any time, energy consumption is very big, only just descends with heat insulation effect after 3 years, keeps in repair numerous and diverse, the cost height, metal shell is perishable.In order to overcome the above problems, the vacuum refrigerator of the 4th page of publication of " radio " 2002 10 monthly magazines Japanese Matsushita Electric Industrial company development must so improve heat-insulating property, but cost is very expensive.

Summary of the invention

Deficiency at above technology, the utility model: a kind of vacuum heat-preserving case is provided, this incubator ectonexine casing is all made with nonmetallic materials, thermal conductivity factor is low, the acid and alkali resistance corrosion, constitute vacuum heat-insulating layer between the two tanks, saved pernicious gas that filling with insulation material polyurethane foam process process produced to people's harm with to the pollution of environment.Should the cost of material is low, not perishable, this kind vacuum heat-preserving case has not only improved heat-insulating property greatly, has cut down the consumption of energy, price only is 1/3 of Panasonic's product.

The utility model solves technical scheme that its technical problem adopts: the vacuum heat-preserving case comprise inside and outside layer box body and between heat-insulation layer and the band heat-insulation layer door, it is characterized in that: inside and outside two layer box bodies are all made with the two-sided multiple film bamboo plywood of environment-friendly type for building, on inside and outside two layer box body opposite faces, be stained with 0.5 millimeters thick sheet plastic, constitute an enclosed vacuum insulation cavity layer between two-layer by inside and outside, a vacuum heat-preserving sealed door is formed the insulation casing, and a thimble valve of taking out air formation vacuum in voided layer, the hollow-core door is installed respectively on casing and door.Be embedded with the sheet iron bar in the casing surrounding, contact the corresponding position with main body case sheet iron bar at door the magnetic door strip of paper used for sealing is installed, finish thermal-insulating sealing.

The contrast prior art, the beneficial effects of the utility model are: this vacuum heat-preserving case is made with nonmetallic materials cheaply, and is nonhygroscopic, the intensity height, toughness is strong, and is wear-resistant, bearing capacity, impact resistance are all strong, high temperature resistant 90 ℃, low temperature-60 ℃, thermal conductivity factor is low, has only 0.14 to 0.16, the acid and alkali resistance corrosion, anti-damaging by worms owing to be stained with sheet plastic at the heat-insulation layer inwall, can not leaked gas under 4 atmospheric pressures, production equipment, technology are simple, make easily empty.Vacuum heat-preserving is higher more than 6 times than polyurethane heat preservation effect.
