Abstract

A plate-shaped chemical heat storage comprising a substrate composed of a net made of metal and a heat storage material composition supported on the substrate, wherein the heat storage material composition comprises at least one selected from the group consisting of magnesium hydroxide or oxide, strontium hydroxide or oxide, barium hydroxide or oxide, calcium hydroxide or oxide, and calcium sulfate, and optionally at least one selected from the group consisting of titanium dioxide, silicon dioxide, alumina silicate fiber, E-glass fiber and cellulose.

First claim

The invention claimed is:

1. A plate-shaped chemical heat storage comprising a substrate composed of a metal net and a layer of a heat storage material composition, wherein the heat storage material is supported on the substrate,
wherein the heat storage material composition comprises a chemical heat storage material and at least one additive selected from the group consisting of titanium dioxide, silicon dioxide, alumina silicate fiber, E glass fiber, and cellulose,
wherein the plate-shaped chemical heat storage has a plate thickness of 0.3 mm or more and 2 mm or less and has a waveform shape having an amplitude higher than the plate thickness and an outer surface layer composed of the heat storage material composition is arranged along the outer surfaces of the metal net.

2. The plate-shaped chemical heat storage according to claim 1 , wherein the at least one additive further comprises an additional additive selected from the group consisting of a heat conductive filler, reinforcing fibers, other than alumina silicate fiber and/or E glass fiber if already present, and binder, other than cellulose if already present.

3. The plate-shaped chemical heat storage according to claim 1 , wherein a total amount of the at least one additive is not less than 1% by weight and not more than 40% by weight with respect to a total amount of the chemical heat storage material.

4. The plate-shaped chemical heat storage according to claim 1 , wherein the metal net comprises at least one selected from the group consisting of stainless steel, aluminum, aluminum alloy, copper and copper alloy.

5. The plate-shaped chemical heat storage according to claim 1 , wherein the metal net is composed of an expanded metal.

6. The plate-shaped chemical heat storage according to claim 1 , wherein a mesh size of the net is 10 μm or more and not more than 5 mm.

7. The plate-shaped chemical heat storage according to claim 1 , wherein the heat storage material composition is supported on the substrate by applying a slurry or paste of the heat storage material composition thereto or compacting a powder of the heat storage material composition therewith.

8. A chemical heat storage system comprising the plate-shaped chemical heat storage according to claim 1 .

9. A chemical heat storage structure composed of a stacked product comprising at least one of the plate-shaped chemical heat storage according to claim 1 .

10. A chemical heat storage system comprising the chemical heat storage structure according to claim 9 .

11. A plate-shaped chemical heat storage comprising a substrate composed of a metal net and a layer of a heat storage material composition, wherein the heat storage material is supported on the substrate,
wherein the heat storage material composition comprises at least one selected from the group consisting of magnesium hydroxide or oxide, strontium hydroxide or oxide, barium hydroxide or oxide, calcium hydroxide or oxide, and at least one additive selected from the group consisting of titanium dioxide, silicon dioxide, alumina silicate fiber, E glass fiber, and cellulose,
wherein the plate-shaped chemical heat storage has a plate thickness of 0.3 mm or more and 2 mm or less and has a waveform shape having an amplitude higher than the plate thickness and an outer surface layer composed of the heat storage material composition is arranged along the outer surfaces of the metal net.

12. The plate-shaped chemical heat storage according to claim 11 , wherein the at least one additive further comprises an additional additive selected from the group consisting of a heat conductive filler, reinforcing fibers, other than alumina silicate fiber and/or E glass fiber if already present, and binder, other than cellulose if already present.

13. The plate-shaped chemical heat storage according to claim 11 , wherein a total amount of the at least one additive is not less than 1% by weight and not more than 40% by weight with respect to a total amount of the chemical heat storage material.

14. The plate-shaped chemical heat storage according to claim 11 , wherein the metal net comprises at least one selected from the group consisting of stainless steel, aluminum, aluminum alloy, copper and copper alloy.

15. The plate-shaped chemical heat storage according to claim 11 , wherein the metal net is composed of an expanded metal.

16. The plate-shaped chemical heat storage according to claim 11 , wherein a mesh size of the net is 10 μm or more and not more than 5 mm.

17. The plate-shaped chemical heat storage according to claim 11 , wherein the heat storage material composition is supported on the substrate by applying a slurry or paste of the heat storage material composition thereto or compacting a powder of the heat storage material composition therewith.

18. A chemical heat storage system comprising the plate-shaped chemical heat storage according to claim 11 .

19. A chemical heat storage structure composed of a stacked product comprising at least one of the plate-shaped chemical heat storage according to claim 11 .

20. A chemical heat storage system comprising the chemical heat storage structure according to claim 19 .
