First, the phase change material 11 is stored in the left storage chamber 15, when it is needed to work, first, according to the working requirement, it is determined how many heat pipes 5 are needed to exchange heat, then the corresponding number of feeding switch valves 20 are opened, then the switch valves 18 on the feeding main pipeline 17 are opened, and the phase change material 11 is input, in this mode, the phase change material 11 generally selects a liquid phase change material, which is convenient for input and recovery. After the phase change material 11 is input into the corresponding heat pipe 5, the lower end of the electric heating rod 6 starts to work, the part of the electric heating rod 6 in contact with the heat pipe 5 exchanges heat with the phase change material 11 in the heat pipe 5, when the heat exchange process reaches the heat exchange time, the air inlet motor 30 starts to work, the output shaft of the air inlet motor 30 is connected with the air inlet cover 29, drives the air inlet cover 29 to rotate, and the first air inlet 34 on the air inlet cover 29 slowly overlaps the second air inlet 35 on the heat preservation layer 9, the overlapping part forms an air inlet channel, cold air enters the heat core heat storage module 1 through the air inlet channel, and the cold air is in contact with the heat pipes 5 in the heat core heat storage module 1, so that the cold heat exchange is realized. The cold air is heated to become hot air and directly flows to the upper end of the heat core heat storage module 1, the dust cover 13 is taken away at this time, so that space and channels are left for the hot air to flow out. If it is needed to store the hot air, a hot gas pipeline can be externally connected to output and store the hot air. The overall working state is that: the phase change material 11 in the heat pipe 5 is vaporized into high-temperature gas under heat, exchanges heat with the cold air entering from outside, the cold air becomes high-temperature hot gas and flows out of the heat core heat storage module 1, and the phase change material 11 in the heat pipe 5 is liquefied into liquid after heat exchange and then drops into the heat pipe 5, and then is heated by the electric heating rod 6 in the heat pipe 5, is vaporized into high-temperature gas again, and the heat exchange is repeated. When the heat exchange is finished, after the phase change material 11 in the heat pipe 5 is completely cooled, if there is unused phase change material 11 in the left storage chamber 15, the left reflux main pipeline 22 is not opened but closed, the right reflux main pipeline 25 is opened, the phase change material 11 is refluxed into the right storage chamber 16 through the work of the reflux pump 21, the reflux switch valve 26 and the discharge switch valve 27, and is stored separately. The significance of separate storage is that, in the use process of the phase change material, with the increase of the cold and heat cycle times, the heat storage (cold storage) capacity will be attenuated, and even the phase change will not occur, so that the phase change materials 11 with different use times can be effectively stored separately.When using in the next stage, the phase change material 11 in the left storage chamber 15 can be released and output to the heat pipe 5 first, and if more phase change material 11 is needed, the phase change material 11 can be released through the right storage chamber 16, because the feeding switch valve 20 is arranged in array on the feeding sub-pipe 39, and the material outlet pipe 19 is controlled singly, so the mixed use of the phase change material 11 is avoided, and the service life of the phase change material 11 can be kept as long as possible. And the phase change material 11 is stored in the storage chamber, so the replacement can be more convenient. The electric heating rod 6 can be used as the heating medium, and the heating medium can be adjusted according to the electricity price and working environment of different areas, or the heat pipe 5 can be heated by using high-temperature waste gas or high-temperature waste water as the heating medium, and the heating medium and the heating mode are not unique.
