Embodiment Construction

[0022] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0023] combine figure 1 and figure 2 , the first embodiment of the present invention is:

[0024] Heat accumulator 1 takes heat directly from the heat source and stores it. To ensure the working temperature T1 (800-1200K) of the high temperature end of AMTEC (integration). Due to the direct heat conduction of the outer wall of AMTEC (integration), the temperature T3 of the low temperature end of AMTEC (integration) is 400-600K. To utilize this heat, the AMTEC (integrated) can be connected to the sodium-sulfur battery (integrated) through a thermally conductive connector, such as figure 2 shown. Through this connector, the normal operating temperature of the sodium-sulfur battery (integrated) can be guaranteed. This utilizes the heat from the low temperature end of the AMTEC (integrated) to improve energy efficiency.

[0025] see figure 2 Shown is the con...
