Abstract

A reaction material formed body into which a reaction material reacting with a reaction medium to store or release heat is formed includes first and second opposite surfaces and multiple heat transfer enhancing members extending at least from the first surface to the second surface. At least two or more of the heat transfer enhancing members are oriented in a predetermined single direction.

First claim

What is claimed is:

1. A reaction material formed body into which a reaction material is formed, the reaction material reversibly reacting with a reaction medium to store or release heat, the reaction material formed body comprising:
first and second opposite surfaces; and
a plurality of heat transfer enhancing members extending at least from the first surface to the second surface,
wherein at least two or more of the heat transfer enhancing members are oriented in a predetermined single direction, and
wherein the heat transfer enhancing members include respective projecting parts projecting from at least one of the first surface and the second surface.

2. The reaction material formed body as claimed in claim 1 , wherein the projecting parts of the heat transfer enhancing members are oriented in a same direction.

3. The reaction material formed body as claimed in claim 1 , wherein all of the heat transfer enhancing members are oriented in the predetermined single direction.

4. The reaction material formed body as claimed in claim 1 , wherein the heat transfer enhancing members have one of a needle shape, a string shape, and a thin strip shape.

5. The reaction material formed body as claimed in claim 1 , wherein the heat transfer enhancing members are formed of a material having toughness.

6. The reaction material formed body as claimed in claim 1 , wherein the heat transfer enhancing members are formed of a flexible string-shaped material.

7. The reaction material formed body as claimed in claim 1 , wherein the heat transfer enhancing members include carbon fibers.

8. A heat storage and release unit, comprising:
a reaction material formed body into which a reaction material is formed, the reaction material reversibly reacting with a reaction medium to store or release heat, the reaction material formed body including
first and second opposite surfaces; and
a plurality of heat transfer enhancing members extending at least from the first surface to the second surface,
wherein at least two or more of the heat transfer enhancing members are oriented in a predetermined single direction;

a reaction material accommodating part accommodating the reaction material formed body and including a heat transfer surface that exchanges heat with the reaction material formed body; and
a reaction material pressing member configured to press the reaction material formed body against the heat transfer surface.

9. The heat storage and release unit as claimed in claim 8 , further comprising:
a deformable heat transfer member provided between the heat transfer surface and the reaction material formed body.

10. A heat storage and release unit, comprising:
the reaction material formed body as set forth in claim 1 ;
a reaction material accommodating part including a heat transfer surface that exchanges heat with the reaction material formed body and accommodating the reaction material formed body so that the projecting parts of the heat transfer enhancing members come into contact with the heat transfer surface; and
a reaction material pressing member configured to press the projecting parts against the heat transfer surface.

11. The heat storage and release unit as claimed in claim 10 , further comprising:
a deformable heat transfer member provided between the heat transfer surface and the reaction material formed body.

12. A heat storage and release unit, comprising:
a reaction material formed body into which a reaction material is formed, the reaction material reversibly reacting with a reaction medium to store or release heat, the reaction material formed body including
first and second opposite surfaces; and
a plurality of heat transfer enhancing members extending at least from the first surface to the second surface,
wherein at least two or more of the heat transfer enhancing members are oriented in a predetermined single direction;

a reaction material accommodating part accommodating the reaction material formed body and including a heat transfer surface that exchanges heat with the reaction material formed body; and
a reaction material pressing member configured to press the reaction material formed body against the heat transfer surface,
wherein a reaction medium flow passage for a reaction medium to flow through is formed on at least one of a contact surface of the reaction material formed body that comes into contact with the reaction material accommodating part and a contact surface of the reaction material formed body that comes into contact with the reaction material pressing member.
