Abstract

The utility model belongs to composite material, relating to a vacuum heat-insulating plate, which consists of a getter, a core material and an aluminum bag. The vacuum heat-insulating plate takes ultra-fine glass fiber cotton plate which is produced by a wet method as a core material, the glass fiber cotton plate is provided with an opening, the getter for absorbing moisture, oxygen, nitrogen and other micromolecule gases is put at the opening after being dried, and the getter is put into an aluminum plastic bag to vacuumize and seal. The vacuum heat-insulating plate has the heat conduction coefficient of 0.0037w/m.K, can be used for temperature preservation in refrigeratories and ice tanks.

Description

Vacuum insulation panel

Technical field:

The utility model belongs to composite material, is a kind of vacuum insulation panel.

Background technique:

Vacuum insulation panel is called the VIP plate again, is usually used in space flight and aviation, household electrical appliances, aspects such as building.In space flight and aviation, polyurethane foam used to be used in the household electrical appliances aspect; Building aspect styrofoam commonly used or hollow glass microbead, thermal conductivity be at 0.018-0.30W/m.k, and thicker.Select for use vacuum insulation panel that thermal conductivity is dropped to below the 0.0037W/m.k, thickness is kept to the 1/5-1/6 of polyurethane layer or styrofoam simultaneously.

Vacuum insulation panel is made of core, sorbent and package bag.The general organic class of core American-European countries of VIP as foamed polystyrene board, polyurethane foam board, polyethylene foam plate etc., Asian countries generally adopts the glass fibre cotton plate of mineral-type.What at present, employing inorganic glass fiber cotton was cooked core all is the glass fibre cotton of the dry production of usefulness.

The glass wool of dry production has forming degree poor, the aluminium foil that easily punctures, shortcomings such as the excessive difficult filling of volume.So preferably use the glass wool of wet production instead.

Summary of the invention:

Given this, the purpose of this utility model is to provide a kind of vacuum insulation panel, it is made of getter 4, core 5, aluminium bag 3, adopt the cotton plate 1 of ultra-fine fibre glass of wet production to do core 5, have hole 2 on the core 5 and in the hole, be placed with getter 4, its thermal conductivity is about 0.0037w/m.K, can be used for refrigerator, refrigerator-freezer insulation.

Description of drawings:

Fig. 1 is the core perforate schematic representation of vacuum insulation panel of the present utility model:

Fig. 2 is a vacuum insulation panel structural representation of the present utility model:

Embodiment:

The purpose of this utility model is achieved through the following technical measures: the cotton plate of ultra-fine fibre glass of wet production of selecting predetermined thickness for use is as core, but one deck also can be multilayer laminated, perforate onboard, oven dry then, put into the getter of hygroscopic moisture, oxygen, nitrogen and other micro-molecular gas again, vacuumize sealing and promptly get vacuum insulation panel through putting into the special-purpose Aluminum-plastic composite bag of VIP at last.

Adopt the thermal conductivity of the vacuum insulation panel of the compound preparation of this method to be about 0.0037w/m.K, can be used for refrigerator, refrigerator-freezer insulation.

Claims (1)

1. a vacuum insulation panel is characterized in that, it is made of getter, core, aluminium bag, has the hole on the core and be placed with getter in the hole.
