Embodiment Construction

[0019] The present invention will be described in detail below. As described above, the thermal storage material of the present invention includes: 100 parts by weight of the basic component and 0.5-1 part by weight of at least one thermal storage enhancing component. The basic component is composed of 60-90 parts by weight of hydrotalcite compound and the balance including at least one of zinc oxide and conductive zinc oxide; the heat storage enhancing component is selected from the group of zirconia components and zirconium carbide.

[0020] The hydrotalcite compounds described herein are defined as double hydroxides represented by the general formula:

[0021] [Ma 2+ 1-x MB 3+ x (OH) 2 ] x+ [A n- x / n ·yH 2 O],

[0022] where Ma 2+ is a divalent metal ion such as Mg 2+ 、Co 2+ 、Ni 2+ and Zn 2+ , Mb 3+ is a trivalent metal ion such as Al 3+ , Fe 3+ and Cr 3+ , and A n- is an n-valent anion such as OH - , Cl - , CO 3 2- and SO 4 2- . Usually, x and y ...

Abstract

There is provided a novel heat regenerating element having an excellent heat regenerating property which can accumulate thermal energy and effectively radiate the accumulated thermal energy to various objects. The present invention further provides a heat regenerating material including the heat regenerating element. The heat regenerating element of the present invention includes: 100 parts by weight of a base component composed of 60 to 90 parts by weight of a hydrotalcite compound and a remnant including at least one of zinc oxide and electrically-conductive zinc oxide; and 0.5 to 1 parts by weight of at least one heat regeneration enhancing component selected from a group of zirconium oxide components and zirconium carbide components.

Description

[0001] Cross-references to related applications [0002] Japanese Patent Application No. 2011-001070, the priority application on which this patent application is based, is incorporated herein by reference. technical field [0003] The present invention relates to heat regenerating elements that store thermal energy and efficiently radiate the stored heat energy to various targets, and in particular, are novel and have excellent heat storage performance. The present invention also relates to a thermal storage blank comprising the above-mentioned thermal storage material. Background technique [0004] Conventionally, various materials including, for example, ceramics such as alumina, titania, zirconia or silica are used as heat storage materials. Improved heat energy absorption efficiency and heat energy radiation efficiency can be provided to heat regenerating materials by including these heat storage materials. This thermal storage blank can be used for heating, cooling a...
