Curved shape vacuum insulation panel and production method

Technical field

The present invention relates to curved shape vacuum insulation panel and production method thereof.

Background technique

Vacuum insulation panel (VIP) is owing to can avoid cross-ventilation to conduct heat effectively, so thermal conductivity is very low, is a kind of thermal insulation material.Completely cut off transmission of heat through improving internal vacuum to greatest extent, reach insulation, purpose of energy saving.One Chinese patent application number is that 200610021567.2 application for a patent for invention discloses a kind of vacuum insulation panel and production method; This vacuum insulation panel adopts the heatproof insulating fibre material as core; Put into the sorbent that the getter of adsorbable moisture, adsorption of oxygen, absorption nitrogen and other micro-molecular gas mixes again, hold in the package bag of above-mentioned core and sorbent and its inside is vacuumized and is sealed to form.Chinese patent number is 200920082835.0, and the model utility of (notice of authorization number be 201599534U) discloses a kind of ultra-thin MULTILAYER COMPOSITE vacuum insulation panel; Constitute by three kinds of materials; These three kinds of materials are Aluminum-plastic composite bag, getter and core, are with the oven dry of multilayer core and getter and put into Aluminum-plastic composite bag and vacuumize encapsulation and get.Present vacuum insulation panel is planar, for example can't be applied on the non-flat plate-like product such as spherical shape, round barrel shape.Chinese patent number is that the application for a patent for invention of 201010547611.X discloses a kind of vacuum heat sealing machine that is suitable for vacuum insulation panel; Has the casing that two ends connect; The middle part of casing is a vacuum chamber of placing vacuum insulation panel; Two ends are vacuum heat-sealing chambeies; Be provided with the heat seal assembly in each vacuum heat-sealing chamber, respectively be hinged with cover plate on the opening of tank ends.The vacuum heat-insulation boards half-finished product that need seal is put into vacuum chamber, and two ends are in the vacuum heat-sealing chamber, after vacuumizing, two ends are sealed, and to slowly air inlet of vacuum chamber, open cover plate again, take out vacuum insulation panel.

Summary of the invention

The objective of the invention is to propose a kind of easily manufactured curved shape vacuum insulation panel and production method.

For one of achieving the above object; The present invention takes following technological scheme: the curved shape vacuum insulation panel that the present invention proposes; Comprise core and aluminum-plastic composite membrane bag; Rule is distributed with convex on one side of said core; Core is in the aluminum-plastic composite membrane bag, and the vacuum insulation panel that after vacuumizing encapsulation, forms is had an edgewise bend of convex to the normal pressure conversion and to core by negative pressure with environment of living in.

The cross section of convex is a rectangle.

The convex profile that forms the arcuation thermal baffle is a strip.

The convex profile that forms the spherical shape thermal baffle is the square shape.

For achieve the above object two, have following steps:, make that rule is distributed with convex on the side of core 1. to core processing; 2. core is in the aluminum-plastic composite membrane bag of one or both ends opening, forms semi-finished product; 3. semi-finished product are put into the vacuum chamber of vacuum heat sealing machine; Setting value to be evacuated down to is after the aluminum-plastic composite membrane bag sealed, again to the slowly air inlet of vacuum chamber of vacuum heat sealing machine; Vacuum insulation panel in the vacuum chamber has an edgewise bend of convex gradually to core, reach the curved that presets.

Above-mentioned steps 1. in, directly process the concavo-convex core that a side has convex by special device.

Above-mentioned steps 1. in, employing be slab, large stretch of and by specification requirement cutting core, and the core small pieces are layered on the core sheet by the spacing requirement between the convex as the core small pieces of convex.

The cross section of convex is a rectangle.

The convex profile that forms the arcuation thermal baffle is a strip.

The convex profile that forms the spherical shape thermal baffle is the square shape.

The present invention utilizes the concavo-convex of core; Crooked with variation in pressure in the vacuum heat sealing machine in the manufacture process; So it is easily manufactured; Having solved in the past, vacuum insulation panel can only be used for upright bin; For example the tank wall of refrigerator has solved for forniciform casing for example barrel-shaped, sphere shape and can't use the problem of vacuum insulation panel.
