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 (100-1300 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 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, comprises 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. |
