| 摘要 |
The present invention relates to a metal heat storage apparatus used to store heat transmitted from the outside, and in particular, the present invention aims to provide a metal heat storage apparatus which stores, at a high temperature, high-temperature solar energy collected by means of a solar concentrator and such others, and allows a gradual discharge thereof, thereby significantly improving the storage of solar energy, which is a natural energy. The present invention doubly insulates a metal heat storage medium, which stores solar energy at a high temperature (100 to 1300 degrees), and disposes a heat exchanger so as to be proximal to the metal heat storage medium, so that a working heating fluid can be heated for an extended period, wherein, in order to doubly insulate the metal heat storage medium: a medium insertion chamber doubly has an arrangement of an insulating inner wall, an insulating outer wall and an insulating floor on the inner side, outer side and the floor, respectively, of the metal heat storage medium; an outer wall structure, made of concrete, includes a floor, a central column, an outer wall body, and an upper cover; a mirror for reflecting infrared rays is disposed below the upper cover; and a heat storage tank is vacuum-treated, thus blocking the air-induced convective process and heat conduction, and thereby allowing the loss of heat to be minimized. |

1. A metal heat storage apparatus comprising:
a metal heat storage medium 2 which is disposed in a ring type or in a quadrangular type; a medium insertion chamber 3 is formed by disposing an insulating inner wall 32, an insulating outer wall 33 and an insulating floor 34, each of which is made of an inner insulating wall body 31 so as to insulate the metal heat storage medium 2, on the inner side, outer side and the floor, respectively, of the metal heat storage medium 2; an outer wall structure 4 which is made of concrete to insulate the metal heat storage medium 2 again and includes a floor 41, a central column 42, an outer wall body 43, and an upper cover 44; a infrared rays reflecting mirror 5 which is disposed below the upper cover 44 constituting the outer wall structure 4 and reflects infrared rays generated from the metal heat storage medium 2; a heat exchanger 6 which is spirally disposed inside the metal heat storage medium 2 and includes a supply tube 61 and a drain tube 62 which are exposed to the outside of the outer wall structure 4; a solar heater 7 which is buried in the metal heat storage medium 2; and a high-density optical input port 8 which is installed to pass through the outer wall body 43 and the insulating outer wall 33 so as to provide the solar energy to the solar heater 7. |
