After the assembly, the heat conducting base plate 3 forms the bottom wall of the circulation chamber and the heat conducting top plate 4 forms the top wall of the circulation chamber.
The aforementioned partition plate 2 is fixedly installed in the circulation chamber to divide the circulation chamber into an upper space 11 and a lower space 12. The partition plate 2 is provided with a plurality of through holes 21 which are communicated with the upper layer space 11 and the lower layer space 12. After the foregoing heat-conducting substrate 3 and the heat-conducting top plate 4 are assembled, a certain mass of heat-accumulating medium is added into the circulation chamber, and the heat-accumulating medium may be heat-conducting oil or water. In the starting state, part or all of the thermal storage medium is located in the lower space 12 under the influence of gravity. The aforementioned circulation mechanism is mounted on the housing 1 for driving the heat storage medium in the lower space 12 to transfer into the upper space 11.

In this embodiment, the upper end of the center shaft of the screw blade is fixedly connected with the driving end of the rotary motor 51, and a positioning seat is arranged on the heat conducting substrate 3.
