Abstract

A chemical heat storage device heats a subject to be heated existing in a pipe. The chemical heat storage device includes a reactor that generates heat by chemically reacting with a reaction medium, an absorber that causes an absorbent to absorb and stores the reaction medium, and a connection tube that is connected to the reactor and absorber, for the reaction medium to migrate through. The reactor includes a solid reaction material disposed along an outer peripheral surface of a place where the subject exists in the pipe and a casing that seals the reaction material so as to form a space along an outer peripheral surface of the reaction material. One end of the connection tube is open to the space.

First claim

The invention claimed is:

1. A chemical heat storage device for heating a subject to be heated existing in a pipe, the device comprising:
a reactor that generates heat by chemically reacting with a reaction medium;
an absorber that causes an absorbent to absorb and stores the reaction medium; and
a connection tube that is connected to the reactor and absorber, for the reaction medium to migrate through;
wherein the reactor includes:
a plurality of solid reaction materials disposed to be juxtaposed along an outer peripheral surface of a place where the subject exists in the pipe;
a casing that seals the reaction materials so as to form a space along outer peripheral surfaces of the reaction materials; and
a support that is provided for the reaction material and forms the space
wherein one end of the connection tube is open to the space,
wherein the support includes a first support portion that supports the reaction material to pipe side, and
wherein the first support portion includes a first contact portion in contact with the outer peripheral surface of the reaction material, and presses the reaction material against the pipe with the first contact portion to support the reaction material.

2. The chemical heat storage device according to claim 1 , wherein the reactor further includes a heat insulating material disposed between the space and the casing, and
wherein the support includes a second support portion that supports the heat insulating material to the casing side.

3. The chemical heat storage device according to claim 2 , wherein the second support portion includes a second contact portion in contact with an inner peripheral surface of the heat insulating material, and presses the heat insulating material against the casing with the second contact portion to support the heat insulating material.

4. The chemical heat storage device according to claim 1 , wherein the support is connected to the pipe or the casing at one end of the support.
