One end of the ventilation hole 5 of the fan side heat storage body 401 and the heat exchanger side heat storage body 402 corresponds to the variable frequency fan 10 and the air-liquid plate heat exchanger 9 respectively, and the other end The inlet and outlet of the air-liquid plate heat exchanger 9 are connected through the return air channel 18 of the second cavity 17, and are respectively connected to the liquid inlet pipe 11 and the liquid outlet pipe 12. A circulating pump 24 is installed on the liquid inlet pipe 11. The liquid inlet pipe 11 and the liquid outlet pipe 12 are respectively provided with a second temperature sensor 13 and a third temperature sensor 14. The liquid inlet pipe 11 and the liquid outlet pipe 12 are connected to the oil storage tank 26 outside the container 1 through a flange 25, and stop valves 27 are provided on both sides of the flange 25.

[0020] The container 1 may be provided with an air conditioner 28, which is activated when the inverter 21 and the battery 22 are not at a suitable working temperature; in places with snow in winter, a sloping roof 29 structure may be added to the container to improve safety and work efficiency.

[0021] When in use, the electric energy generated by the solar photovoltaic power generation equipment is first stored in the battery 22, and the direct current in the battery 22 is converted into alternating current through the inverter 21. The inverter 21 is connected to the terminal 19 of the heating tube 6 through the wire 20. At this time, the heat storage body 4 can be heated. During the heating period, in order to prevent the high temperature from affecting the air-liquid plate heat exchanger 9 and the variable frequency fan 10 when they are shut down, the insulation board 2 needs to fall to separate the first cavity 16 and the second cavity 17, and the heating is stopped when the first temperature sensor 7 detects that the heating has reached the highest temperature.
