Vacuum insulation panel
The invention provides a vacuum insulation panel to which moisture and gas do not easily adsorb while it is being processed or being in storage in an unfinished state. The vacuum insulation panel includes a core provided with air circulation, a getter material which adsorbs moisture and gas from the core, an inner film bag which accommodates the core and the getter material, and an outer barrier bag which accommodates the inner film bag. The getter material is filled in an incision provided on the surface of the core. To prevent the getter material from getting out of the incision, the opening of the incision is narrowed by evacuating air from the interior of the inner film bag and, concurrently, compressing the inner film bag and the core.
1. A vacuum insulation panel, comprising:
a core made of an inorganic fiber assembly,
a getter material which adsorbs moisture and gas from the core, and
an outer barrier bag which accommodates the core and the getter material, wherein;
the core has only one vertical incision that linearly extends on the widest surface of the core and is cut to a depth and a length capable of holding the getter material,
the getter material is held in the vertical incision, and
the core is configured, using an inorganic fiber laminate containing no binder, such that an opening of the vertical incision is compressed so as to be narrowed in a state where the getter material is accommodated.
2. The vacuum insulation panel according to claim 1 , wherein the opening of the vertical incision extends from the widest surface of the core toward an interior of the core.
3. The vacuum insulation panel according to claim 1 , wherein the core has a pair of opposed major surfaces and the vertical incision is provided on one of the opposed major surfaces of the core such that the opening extends from the one of the opposed major surfaces of the core toward an interior of the core.
4. The vacuum insulation panel according to claim 1 ,
wherein the core comprises an inorganic fiber layer with the vertical incision in a thickness direction and an inorganic fiber layer without the vertical incision, and
the vertical incision passes through one side to the other side of the inorganic fiber layer with the vertical incision.
5. The vacuum insulation panel according to claim 1 , wherein the getter material comprises a plurality of particles.
6. A vacuum insulation panel, comprising:
a core made of an inorganic fiber assembly,
a getter material which adsorbs moisture and gas from the core,
an inner film bag which accommodates the core, and
an outer barrier bag which accommodates the inner film bag, wherein;
the core has only one vertical incision that linearly extends on the widest surface of the core and is cut to a depth and a length capable of holding the getter material,
the getter material is held in the vertical incision, and
an opening of the incision is narrowed by evacuating air from an interior of the inner film bag and compressing the inner film bag and the core in the state where the getter material is accommodated.
7. The vacuum insulation panel according to claim 6 , wherein the opening of the vertical incision extends from the widest surface of the core toward an interior of the core.
8. The vacuum insulation panel according to claim 6 , wherein the core has a pair of opposed major surfaces and the vertical incision is provided on one of the opposed major surfaces of the core such that the opening extends from the one of the opposed major surfaces of the core toward an interior of the core.
9. The vacuum panel according to claim 6 ,
wherein the core comprises an inorganic fiber layer with the vertical incision in a thickness direction and an inorganic fiber layer without the vertical incision, and
the vertical incision passes through one side to the other side of the inorganic fiber layer with the vertical incision.
10. The vacuum insulation panel according to claim 6 , wherein the getter material comprises a plurality of particles.
11. A vacuum insulation panel, comprising:
a core made of a material through which air can circulate,
a getter material which adsorbs moisture and gas from the core,
an inner film bag which accommodates the core and the getter material, and
an outer barrier bag which accommodates the inner film bag, wherein;
the core has only one vertical incision that linearly extends on the widest surface of the core and is cut to a depth and a length capable of holding the getter material,
the getter material is filled in the vertical incision, and
an opening of the vertical incision is, to prevent the getter material from getting out of the opening, narrowed by evacuating air from an interior of the inner film bag and compressing the inner film bag and the core is a state where the getter material is accommodated.
12. The vacuum insulation panel according to claim 11 , wherein the opening of the vertical incision extends from the widest surface of the core toward an interior of the core.
13. The vacuum insulation panel according to claim 11 , wherein the core has a pair of opposed major surfaces and the vertical incision is provided on one of the opposed major surfaces of the core such that the opening extends from the one of the opposed major surfaces of the core toward an interior of the core.
14. The vacuum insulation panel according to claim 11 ,
wherein the core comprises an inorganic fiber layer with the vertical incision in a thickness direction and an inorganic fiber layer without the vertical incision, and
the vertical incision passes through one side to the other side of the inorganic fiber layer with the vertical incision.
