| 摘要 |
The present invention relates to a metal heat storage apparatus which is used for storing heat transferred from an outside, and more particularly, to a metal heat storage apparatus which is capable of gradually emitting solar thermal energy which is accumulated at high temperature (100 ~ 1,300 degrees) through a solar heat collecting device so that the storage of solar heat which is natural energy can be remarkably improved. According to the present invention, a metal heat storing medium for storing solar thermal energy is dually heat-insulated and a heat exchanger is installed to be closed to the metal heat storing medium such that heating water can be heated for a long time. A heat insulation inner wall, a heat insulation outer wall and a heat insulation bottom, which serve as a dual heat insulating means for heat insulating the metal heat storing medium, are disposed at an inside, an outside and a bottom of the metal heat storing medium to form a medium receiving chamber. An outer wall structure made of concrete includes a bottom, a central pillar, an outer wall and an upper cover. An infrared ray reflecting mirror and a heat storing tank installed below the upper cover are vacuum treated so that convection and heat conduction can be prevented by air, thereby minimizing heat loss. |
