Abstract
Abstract A hollow plate-like panel comprising at least two face plates spaced apart at a given distance from each other and a core member composed of a plurality of unit cells and sandwiched between the face plates, at least one hole being provided in at least one face plate and each unit cell having at least two holes communicating with adjoining unit cells, is suitable for filling a solidifiable heat storage material to give a heat storage material panel with high strength and durability.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
74 words
A hollow plate-like structure for heat storage material panel, comprising at least two face plates spaced apart at a given distance from each other, and a core member composed of an assemblage of a plurality of unit cells and sandwiched between said face plates, at least one hole being provided in at least one end plate, and each unit cell in said core member having at least two holes communicating with adjoining unit cells.
Claim 2
Dependent Claim
74 words
A hollow plate-like structure for heat storage material panel, comprising at least two face plates spaced apart at a given distance from each other, and a core member composed of an assemblage of a plurality of unit cells and sandwiched between said face plates, at least one hole being provided in at least one end plate, and each unit cell in said core member having at least two holes communicating with adjoining unit cells.
Claim 3
Dependent Claim
46 words
A hollow plate-like structure according to Claim 1, wherein the thickness of the hollow plate-like panel is 5 to 50 mm, the sectional average area of the unit cell is 20 to 10000 mm2, and the thickness of the face plate is 0.1 to 3 mm.
Claim 4
Dependent Claim
32 words
A hollow plate-like structure according to Claim 1, wherein the unit cell has a polygonal, circular, oval, fan-shaped shape or a combined form of circles and polygonal shapes as a section shape.
Claim 5
Dependent Claim
36 words
A hollow plate-like structure according to Claim 1, wherein at least two holes are provided in at least one end plate and at least two holes are placed oppositely at both end portions of the plate.
Claim 6
Dependent Claim
82 words
A method for producing a heat storage material panel by using a hollow plate-like structure for heat storage material panel of Claim 1, which comprises evacuating the air in the interior of the hollow plate-like structure from at least one hole provided in at least one face plate of said structure, and concurrently with or after the evacuation, supplying a solidifiable heat storage material to fill the structure from one or more other holes or from the hole used for the evacuation.
