## Abstract

A heat storage system using a heat storage container includes a tubular body, a chemical heat storage material accommodated in the tubular body, and a flow channel that penetrates the tubular body in a longitudinal direction. The heat storage system includes a diffusion layer for transporting liquid from the flow channel to the chemical heat storage material. The liquid functions as a reaction medium of the chemical heat storage material. The liquid is transported to the flow channel and the diffusion layer. The liquid transported to the diffusion layer reacts with the chemical heat storage material, the chemical heat storage material generates heat, and the liquid is vaporized by the heat to become heat transport fluid.

## Claims

### Claim 1

A heat storage container comprising:
a tubular body;
a chemical heat storage material accommodated in the tubular body;
a first lid body comprising a central though hole, and is provided adjacent to the chemical heat storage material on a side of one end portion of the tubular body;
a second lid body comprising a central through hole, and is provided adjacent to the chemical heat storage material on a side of another end portion of the tubular body;
a first wick structure that is provided adjacent to inside of the chemical heat storage material between the first lid body and the second lid body, and has a capillary structure; and
a flow channel that is provided inside the first wick structure, and penetrates the tubular body in a longitudinal direction,
by a capillary force of the first wick structure, a liquid heat transport fluid being flow from the one end portion to the other end portion of the chemical heat storage material along a longitudinal direction of the tubular body,
the liquid heat transport fluid functioning as a reaction medium to the chemical heat storage material and functioning as a heat transport fluid for transporting heat stored in the chemical heat storage material to a heat use destination,
the first lid body and the second lid body central through holes each having such a size as to enable passing of the liquid heat transport fluid but not to allow passing of powder of the chemical heat storage material,
wherein the first wick structure is metal mesh, or a metal sintered compact formed by sintering a powdery metal material, and wherein the liquid heat transport fluid is supplied to the one end portion of the chemical heat storage material through the first lid body, wherein one end portion of the first wick structure is in contact with an interior surface of the first lid body, wherein the central through hole of the first lid body forms one open end portion of the flow channel, and another end portion of the first wick structure is in contact with an interior surface of the second lid body, wherein the central through hole of the second lid body forms another open end portion of the flow channel, and wherein the liquid heat transport fluid is supplied from the first lid body to the second lid body through the first wick structure.
