[0021] 5. The energy storage charging device can make the coolant in the inner tube and the sliding cavity flow continuously through the reciprocating sliding slider, and the coolant can evenly distribute the heat on the heat-conducting shell on its surface to improve the uniformity of the surface temperature of the heat-conducting shell, thereby reducing the heat accumulation of the battery.

An air duct 9 is provided. Assuming that there are 3 batteries 2 in each row, the number of air ducts 9 is 4. A ventilation gap 10 is provided between two adjacent rows of heat-conducting shells 3. The cross-sectional area of the ventilation gap 10 is smaller than the cross-sectional area of the air duct 9 when it is open. Ventilation components corresponding to the air duct 9 are provided at the upper and lower ends of the outer shell 1, and the ventilation components are used to dissipate heat from the battery 2 and the heat-conducting shell 3; an opening and closing component is provided on the outer wall of the outer shell 1, wherein the opening and closing component is used to drive two adjacent heat-conducting shells 3 to move closer to and away from each other. When two of the heat-conducting shells 3 are close to each other, the air duct 9 between the two is closed, while the air duct 9 at the adjacent position is opened.

In order to ensure the heat conduction efficiency, a heat-conducting medium can be applied to the outer wall of the battery 2 or a heat-conducting pad can be added.

[0042] Reference Figure 1-Figure 5 , which is basically the same as the first embodiment, and further discloses a specific implementation scheme of the opening and closing components.

[0044] Specifically, during the heat dissipation process, the drive motor 19 is started, and the drive motor 19 will drive one of the rotating rods 16 to rotate, and drive all the rotating rods 16 to rotate under the action of the chain drive 18, all the rotating rods 16 will drive all the reciprocating screws 17 to rotate, and the reciprocating screw 17 will drive the provided slider 15 to slide back and forth in the slide groove 20, and drive the provided heat-conducting shell 3 and the battery 2 to slide back and forth in the outer shell 1, and the air duct 9 formed between the heat-conducting shells 3 will intermittently open and close, and when one of the air ducts 9 is completely closed, the air duct 9 located at its adjacent position will be completely opened, and the reciprocatingly sliding heat-conducting shell 3 can be in more comprehensive contact with the air blowing, so as to improve the heat dissipation efficiency of the heat-conducting shell 3, and indirectly improve the heat dissipation efficiency of the battery 2.
[0045] The outer wall of the housing 1 is fixedly connected with a protective cover 26 , and the slider 15 , the rotating rod 16 and the driving motor 19 are all sleeved in the protective cover 26 . The protective cover 26 can effectively isolate and protect the slider 15 , the rotating rod 16 and the driving motor 19 .
[0046] Embodiment three:
[0047] Reference Figure 3-Figure 6 , which is basically the same as the second embodiment, and further, a specific implementation scheme for improving the heat dissipation efficiency of the heat-conducting shell 3 is specifically added.
[0048] Both sides of each of the above-mentioned heat-conducting shells 3 are fixedly connected to a plurality of first tooth plates 6 integrally formed therewith, and the inner wall of the outer shell 1 is fixedly connected to a plurality of rows of mounting plates 7, and the number of rows of the mounting plates 7 is the same as that of the heat-conducting shell 3, and a plurality of second tooth plates 8 are fixedly connected to the mounting plates 7, wherein tooth grooves 11 are formed between adjacent first tooth plates 6 and second tooth plates 8, and when the two heat-conducting shells 3 are close to each other and the heat-conducting shell 3 is close to the inner wall of the outer shell 1, the first tooth plates 6 and the second tooth plates 8 will be inserted into the tooth grooves 11 at adjacent positions, and the axial cross-sectional shapes of the first tooth plates 6 and the second tooth plates 8 are both trapezoidal, and the axial cross-sectional shape of the tooth grooves 11 is trapezoidal.
[0049] Specifically, since the first tooth plate 6 and the second tooth plate 8 are fixedly installed on both sides of the heat-conducting shell 3 and the mounting plate 7 respectively, the heat dissipation area of the heat-conducting shell 3 can be significantly improved, thereby significantly improving the heat dissipation efficiency of the battery 2. When two of the heat-conducting shells 3 gradually approach each other or the heat-conducting shells 3 on both sides gradually approach the inner wall of the outer shell 1, the two adjacent first tooth plates 6 will gradually mesh with each other, and the adjacent first tooth plates 6 and second tooth plates 8 will also mesh with each other, that is, the first tooth plate 6 will be inserted into the tooth groove 11. Since its cross-sectional shape is trapezoidal, the gap between the first tooth plate 6 and the tooth groove 11, and between the second tooth plate 8 and the tooth groove 11 will gradually decrease, so that the flow rate will gradually increase, which can make it difficult for dust to stay on the first tooth plate 6 and the second tooth plate 8, thereby ensuring the heat dissipation efficiency of the first tooth plate 6 and the second tooth plate 8. When the two adjacent first tooth plates 6 are fully meshed, or the adjacent first tooth plate 6 and the second tooth plate 8 are fully meshed, the air duct 9 will be closed.
[0050] Embodiment 4:
[0051] Reference Figure 4-Figure 7 , which is basically the same as the third embodiment, and further, a specific implementation scheme for improving the heat dissipation efficiency of the heat-conducting shell 3 is specifically added.
[0052] A plurality of inner tubes 22 distributed longitudinally are fixedly provided in the heat-conducting shell 3, each inner tube 22 is filled with coolant, and a circulation portion for driving the coolant to flow continuously is provided in the slider 15; the circulation portion comprises a sliding cavity 21 provided in the slider 15, the sliding cavity 21 is also filled with coolant, a piston plate 23 is slidably installed in the sliding cavity 21, wherein the piston plate 23 is fixedly connected to the inner wall of the slide groove 20 through a support rod 25, and the two ends of the inner tube 22 extend to the two sides of the sliding cavity 21 respectively, a transverse hole 24 is provided on the piston plate 23, and a one-way valve is fixedly installed in the transverse hole 24.
[0053] Specifically, when the slider 15 slides back and forth, the piston plate 23 fixed in the slide groove 20 by the support rod 25 will slide back and forth in the slide cavity 21. When the piston plate 23 slides to one side of the slide cavity 21, the one-way valve in the transverse hole 24 is closed, and the piston plate 23 will push the coolant in the slide cavity 21 to one end of the inner tube 22, and the other end of the inner tube 22 will be transported to the other side of the slide cavity 21. When the piston plate 23 slides back and forth to reset, the one-way valve in the transverse hole 24 will open, and the coolant in the slide cavity 21 will directly pass through the transverse hole 24 instead of being pushed in the opposite direction by the piston plate 23. Therefore, the reciprocating slider 15 will cause the coolant in the inner tube 22 and the slide cavity 21 to flow continuously, and the coolant can evenly distribute the heat on the heat-conducting shell 3 on its surface, so as to improve the uniformity of the surface temperature of the heat-conducting shell 3, thereby reducing the heat accumulation of the battery 2.
[0054] When the energy storage charging device is in use, the battery 2 will transfer the generated heat to the heat-conducting shell 3. At this time, the cooling fans 13 in the two sets of vents 12 are started, and the vents 12 located at the lower end of the shell 1 will blow air into the shell 1, and the vents 12 located at the upper end of the shell 1 will exhaust air to the outside of the shell 1, so that the air will pass through the shell 1 and be discharged. When the airflow enters the shell 1, the airflow will flow along the air duct 9 to complete the heat dissipation of the heat-conducting shell 3 and the battery 2;
[0055] During the heat dissipation process, the drive motor 19 is started, and the drive motor 19 will drive one of the rotating rods 16 to rotate, and drive all the rotating rods 16 to rotate under the action of the chain drive 18, all the rotating rods 16 will drive all the reciprocating screws 17 to rotate, and the reciprocating screw 17 will drive the provided slider 15 to slide back and forth in the slide groove 20, and drive the provided heat-conducting shell 3 and the battery 2 to slide back and forth in the outer shell 1, and the air duct 9 formed between the heat-conducting shells 3 will intermittently open and close, and when one of the air ducts 9 is completely closed, the air duct 9 located at its adjacent position will be completely opened, and the reciprocatingly sliding heat-conducting shell 3 can be in more comprehensive contact with the blowing air, so as to improve the heat dissipation efficiency of the heat-conducting shell 3, and indirectly improve the heat dissipation efficiency of the battery 2.
[0056] like Figure 8 As shown, when the two heat-conducting shells 3 gradually approach each other, the cross-sectional area of the air duct 9 formed between the two heat-conducting shells 3 gradually decreases, and the wind speed in the air duct 9 gradually increases. The changing wind speed makes it difficult for dust in the air to stay on the outer wall of the heat-conducting shell 3, so as to ensure the continuity of heat dissipation of the heat-conducting shell 3. When the two heat-conducting shells 3 are attached (a gap of 0.2mm-1.5mm is left between the two), the dust on the surface will become loose, so that it is easy to fall off from the surface, and most of the airflow will begin to flow along the ventilation gap 1 0 flows on the surface of the heat-conducting shell 3 to increase the heat dissipation area of the heat-conducting shell 3 and reduce the heat accumulation phenomenon in local positions. The airflow flowing horizontally will eventually go from the air duct 9 row that is not aligned with the previous row of air ducts 9 to another row of ventilation gaps 10, and so on, and finally be discharged from the top vent 12 of the shell 1. Therefore, the flowing airflow will reciprocate and return between the multiple heat-conducting shells 3 and flow at a variable speed, so as to significantly increase the heat dissipation area of the heat-conducting shell 3, and make it difficult for dust to stay on the outer wall of the heat-conducting shell 3, thereby indirectly improving the heat dissipation efficiency of the battery 2.
[0057] Since the heat-conducting shell 3 will constantly exchange positions in the outer shell 1, the heat transferred from the heat-conducting shell 3 to the outer shell 1 will not be trapped between the two, but will be carried away by the flowing air flow. This can also reduce the heat accumulation between the heat-conducting shell 3 and the outer shell 1, and indirectly improve the heat dissipation efficiency of the battery 2.
[0058] When the two heat-conducting shells 3 gradually move away from each other, the air flow direction will be as follows: Fig. 9As shown, it is ensured that the flow rate in all the air ducts 9 and the ventilation gaps 10 is changed, and the blowing direction in the ventilation gaps 10 is opposite to the former, so that dust is less likely to stay on the surface of the heat-conducting shell 3, indirectly improving the heat dissipation efficiency of the battery 2.
[0059] When all heat-conducting shells 3 move to the middle position of their maximum travel, all air ducts 9 are in an open state, and the ventilation area is half of the maximum ventilation area. At this time, most of the air will flow directly along the linearly distributed multiple air ducts 9 without reciprocating. The air flow direction is as follows: Fig.10 shown.
[0060] Since the first tooth plate 6 and the second tooth plate 8 are fixedly installed on both sides of the heat-conducting shell 3 and the mounting plate 7 respectively, the heat dissipation area of the heat-conducting shell 3 can be significantly improved, thereby significantly improving the heat dissipation efficiency of the battery 2. When two of the heat-conducting shells 3 gradually approach each other or the heat-conducting shells 3 on both sides gradually approach the inner wall of the outer shell 1, the two adjacent first tooth plates 6 will gradually mesh with each other, and the adjacent first tooth plates 6 and second tooth plates 8 will also mesh with each other, that is, the first tooth plate 6 will be inserted into the tooth groove 11. Since its cross-sectional shape is trapezoidal, the gap between the first tooth plate 6 and the tooth groove 11, and between the second tooth plate 8 and the tooth groove 11 will gradually decrease, so that the flow rate will gradually increase, that is, dust is not easy to stay on the first tooth plate 6 and the second tooth plate 8, thereby ensuring the heat dissipation efficiency of the first tooth plate 6 and the second tooth plate 8. When the two adjacent first tooth plates 6 are fully meshed, or the adjacent first tooth plate 6 and the second tooth plate 8 are fully meshed, the air duct 9 will be closed.
[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
