Description
Technical field
The utility model relates to refrigeration technology field, particularly relates to a kind of vacuum insulation panel and the refrigerator with this vacuum insulation panel.
Background technique
Vacuum insulation panel (Vacuum Insulation Panel is called for short VIP) is in the vacuum protection top layer, to fill core, seals a kind of sheet material that forms after vacuumizing again.Because it avoids cross-ventilation to conduct heat effectively, so thermal conductivity reduces significantly, less than 0.004w/mk, is merely present the most frequently used thermal insulating material---1/4～1/6 of polyurethane rigid foam plastic, is state-of-the-art in the world thermal insulation material.
Compare with other thermal insulating material; VIP is because of having extremely low thermal conductivity; Requiring under the heat insulation effect condition identical with usage space, its soak chamber has thin, little, the lightweight advantage of outer volume of insulation layer thickness, is particularly useful for energy-conservation requirements height, the compact occasion of structural requirement.In the past, VIP is mainly used in fields such as military project, shipping HEATING BOX and medical HEATING BOX.Now, along with the core cost reduces and the expansion of batch process scale, VIP has been widely used in fields such as refrigerator, refrigerator-freezer, refrigerator car, freezer, refrigeration and cold storage shipping container.
VIP mainly is made up of three parts, i.e. the trapping film of the thermal-protective material of core (be core, commonly used such as glass fibre), gas absorption material and sealing (commonly used such as the aluminium bag).Degree of vacuum is the key that guarantees the VIP heat-shielding performance.If degree of vacuum fails to reach requirement, then can have a strong impact on the thermal insulation property of VIP.In order to guarantee degree of vacuum, need do after VIP vacuumizes at last and seal processing (generally adopting secondary to seal enhanced leaktightness).Therefore, can not cut again or perforate after the VIP moulding.
VIP is applied to refrigerator and makes, and needs that VIP is sticked on refrigerator and need strengthen heat insulation position, uses other thermal-protective materials (for example foamed material) to charge into again to carry out behind the casing permanent fixing.There is projection maybe to need punching if need to strengthen heat insulation position, then need adopts polylith VIP assembly unit, so that reserve appropriate gap at the position that has projection maybe need punch.Above-mentioned manufacture process is complex process, complex operation not only, and owing to after the polylith VIP assembly unit, can bring serious edge effect problem, produces the cold draining problem at seam crossing, does not reach desirable effect of heat insulation.
