As a specific implementation, the set of energy releasing coils 41 described in this embodiment includes three U-shaped energy releasing coils 41.
As shown in fig. 1, the first heat-insulating plate is fixedly provided with a first collecting pipe 32 and a second collecting pipe 33, and the second heat-insulating plate is provided with a third collecting pipe 42 and a fourth collecting pipe 43.

Similarly, as shown in fig. 17, the upper wing portions of the energy releasing coil 41 are respectively communicated with the third collecting pipe 42, and the lower wing portions of the energy releasing coil 41 are respectively communicated with the fourth collecting pipe 43.
Because the structures of the first manifold pipe 32, the second manifold pipe 33, the third manifold pipe 42 and the fourth manifold pipe 43, the connection structures between the energy storage coil pipe 31 and the first manifold pipe 32 and the second manifold pipe 33, and the connection structures between the energy release coil pipe 41 and the third manifold pipe 42 and the fourth manifold pipe 43 are the same, in order to avoid repetition, the specific structure of the first manifold pipe 32 and the connection structure between the first manifold pipe 32 and the energy storage coil pipe 31 will be described in detail by taking the first manifold pipe 32 as an example.
As shown in fig. 16, the first manifold 32 includes a plurality of longitudinal manifold portions 321 arranged in parallel, and as shown in fig. 12, the longitudinal manifold portions 321 are fixedly connected to the first insulating cover plate 12 by U-bolts 6. The number of the longitudinal confluence portions 321 is the same as that of the energy storage coils 31 in each group of the energy storage coils 31, the positions of the longitudinal confluence portions 321 correspond to the left side wings of the energy storage coils 31 in the group of the energy storage coils 31 one by one, and preferably, the longitudinal confluence portions 321 are located right above the left side wings of the corresponding energy storage coils 31. The lower side of the longitudinal confluence pipe is provided with a plurality of vertical branch pipes 324 extending downwards along the front-back direction, and the number of the vertical branch pipes 324 on each longitudinal confluence part 321 is the same as the number of the energy storage coil pipe 31 groups, and the positions of the vertical branch pipes are in one-to-one correspondence. The vertical branch pipe 324 penetrates through the first heat-preservation cover plate 12 and extends to the inside of the heat-preservation box body 11, a through hole for accommodating the vertical branch pipe 324 is formed in the first heat-preservation cover plate 12, and the vertical branch pipe 324 is connected with the first heat-preservation cover plate 12 in a sealing mode. As shown in fig. 14, the left side wings of the energy storage coil 31 are respectively connected with the corresponding vertical branch pipes 324 in a sealing manner. As shown in fig. 16, the longitudinal beam converging portions are provided with lateral converging portions 322 at the front and rear ends thereof, respectively, and the longitudinal converging portion 321 communicates with the lateral converging portions 322.

Preferably, a sealing ring (not shown) is disposed on an end surface of the connecting portion 323.
As shown in fig. 22, the inner hole of the coupling nut 7 is in a step hole shape, and sequentially includes a first hole section, a second hole section, and a third hole section along the axial direction, wherein the diameters of the first hole section and the third hole section are equal, and the diameters of the first hole section and the third hole section are smaller than the diameter of the second hole section. The inner cylindrical surfaces of the first hole section and the third hole section are respectively provided with an internal thread matched with the external thread on the connecting part 323, and correspondingly, the rotating directions of the internal threads on the first hole section and the third hole section are opposite.
Thus, when module connection is required, the blocking end caps of the mobile energy supply devices except for the mobile energy supply device at the end are removed, and then the adjacent two connecting portions 323 are connected by the connecting nut 7. Since the threads of the connecting portions 323 of the front and rear sections are opposite to each other for the same mobile energy supply device, when the connecting nut 7 is rotated, the connecting portions 323 on both sides of the connecting nut 7 move toward each other until the end faces of the two connecting portions 323 are pressed against each other.
For the convenience of disassembly, as shown in fig. 15, a stop nut 326 is disposed on the left wing of the energy storage coil 31, and an external thread matching with the stop nut 326 is disposed on the upper end of the left wing of the energy storage coil 31. A compression threaded sleeve 327 is sleeved on the left side wing part of the energy storage coil pipe 31 below the stop nut 326. The pressing thread sleeve 327 comprises a sleeve body, the upper end opening and the lower end of the sleeve body are closed, and a through hole for accommodating the left side wing part of the energy storage coil 31 is formed in the closed end of the sleeve body. An internal thread is arranged on the cylindrical surface of the inner side of the sleeve body, and an external thread matched with the internal thread of the pressing threaded sleeve 327 is arranged at the lower end of the vertical branch pipe 324. The outer side surface of the sleeve body is hexagonal prism-shaped. An annular pressing plate 3241 is arranged on the inner cylindrical surface of the vertical branch pipe 324, and the upper end surface of the left wing part of the energy storage coil pipe 31 is inserted into the vertical branch pipe 324 under the pressing action of the pressing screw sleeve 327 and is pressed on the lower side surface of the annular pressing plate 3241. And a sealing gasket 325 is arranged between the lower side surface of the annular pressing plate 3241 and the upper end surface of the left wing part of the energy storage coil pipe 31.
Further, as shown in fig. 15, an annular extending portion 311 extending upward is disposed at an upper end of a left wing of the energy storage coil 31, an outer diameter of the extending portion 311 is smaller than an outer diameter of the left wing of the energy storage coil 31, and an inner diameter of the extending portion 311 is equal to an inner diameter of the left wing of the energy storage coil 31. The extension 311 and the left wing of the energy storage coil 31 together form a step surface, the stop nut 326 is arranged on the extension 311, and the lower end surface of the stop nut 326 is pressed on the step surface. The outer side surface of the extension 311 is provided with an external thread which is matched with the stop nut 326.
Further, in order to avoid the stop nut 326 being rotated by friction force during the tightening of the compression nut 327, the thread direction of the compression nut 327 is opposite to the thread direction of the stop nut 326.
Further, the insulation box body 11, the first insulation cover plate 12 and the second insulation cover plate 13 are all made of insulation boards. Polyurethane is a common heat-insulating material in the market, is similar to foam-shaped material, and has good heat-insulating effect but low strength. At present, when the thermal insulation box body 11 is made of polyurethane, in order to improve the structural strength of the thermal insulation box body 11, color steel plates are generally added on two sides of the polyurethane to manufacture color steel sandwich plates. Although the structural strength of the heat insulating box 11 can be improved to some extent, the strength is not high. Because the traditional heat preservation box body 11 is generally fixed differently, the color steel sandwich board can meet the design requirements although the structural strength is not high. The device needs to be moved and transported, so if the box body is made of the color steel sandwich panel, the color steel sandwich panel is easy to damage and has short service life.
