PURPOSE: To fabricate heat storage means comparatively economically, by providing thermally insulated regions in an outer and an inner containers which regions are prepared by exhaust gas therebetween and burning out, and extending supporting member for the inner container through the regions. CONSTITUTION: A metal housing 10 is composed of a cylindrical outer container 12 and a cylindrical inner container 14 coaxially disposed therein, and an insulating space 16 is formed between the containers 12 and 14 as a vacuum space made by exhaust gas and burning up. The inner container 14 is provided with a feed duct 20 for a heat transfer medium and a return duct extending in parallel therewith at a dead end 18 of the insulating space 16. The inner container 14 accommodates the heat storage medium disposed in one or plural chambers 22, and the outer container 12 comprises suspension or support member for supporting the inner container 14 therein in such a manner as to avoid heat bridge. |
