PURPOSE:To heat and keep warm in high-temperature type batteries at uniform temperature and also provide excellent heat insulating effect by utilizing vacuum adiabatic technique. CONSTITUTION:The whole outer surface of a high-temperature type battery 12, arranged in the inside of a heat insulation box 11, is wrappedly covered with heat transfer material 13, and also heat insulating material 14 is packed between the heat transfer material 13 and the heat insulation box 11. The heat insulation box 11 is sealed, and then its inside is retained in a vacuum condition. Consequently portions, in which heat bridges like membranes in former vacuum heat insulation boxes, are eliminated in the heat insulation box 11, eliminating heat radiation loss from heat bridges. As a result, very excellent heat insulation effect can be displayed in the heat insulation box 11. The whole outer surface of the high-temperature type battery 12 is wrappedly covered with the heat transfer material 13, unifying temperature at the time of the heating and heat- insulating of every high-temperature type battery 12. |
