[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 7 The present invention provides the following technical solutions: a modular energy storage system for controlling heat dissipation, the energy storage system comprising an independent energy storage frame 1, a cooling system 2, a module support assembly 3 and an independent battery module 9, the side of the cooling system 2 is screwed with a hydraulic rod 27, the end of the hydraulic rod 27 is installed with a loading and unloading unit 4, the cooling system 2 is docked with multiple independent energy storage frames 1 at the same time, and each independent energy storage frame 1 is embedded with multiple module support assemblies 3, the independent battery module 9 is placed on the surface of the module support assembly 3, and a support plate 10 is installed at the bottom of the module support assembly 3, a support shaft 18 is inserted at the bottom of the support plate 10, both ends of the support shaft 18 are welded and fixed to the inner wall of the independent energy storage frame 1, the side of the support plate 10 is in contact with the inner wall of the independent energy storage frame 1, and a plug-in board 7 is integrally formed at the bottom rear end of each independent energy storage frame 1, and the plug-in board 7 is embedded in the interior of the cooling system 2. The modular controlled heat dissipation energy storage system stores and utilizes the transmitted electrical energy with the help of multiple installed independent battery modules 9, and during the energy storage process, the cooling system 2 built at the rear can sustainably provide more targeted cooling treatment for the modular battery structure.

[0029] When the present invention is constructed, each independent battery module 9 is directly placed in the module support assembly 3, and then each independent battery module 9 is placed in the independent energy storage frame 1. Finally, the assembled independent energy storage frame 1 is pushed toward the rear end with the help of the loading and unloading unit 4 until the independent energy storage frame 1 is docked with the cooling system 2 at the rear, so that the low-temperature airflow transported in the cooling system 2 can enter the docked independent energy storage frame 1. After the independent battery module 9 is placed, the module support assembly 3 inside each independent energy storage frame 1 will also automatically control the rotation of the arc plate 15 at the rear end to ensure that the module support assembly 3 can be connected with the cold airflow entering from the rear of the independent energy storage frame 1, so that the low-temperature airflow can finally directly enter the module support assembly 3 where the independent battery module 9 is placed, thereby realizing close-range targeted cooling treatment for each stored independent battery module 9.

[0030] In this embodiment, the module support assembly 3 includes a support plate 10, a slide plate 22 and a front baffle plate 11. The rear end side edge of the support plate 10 is integrally formed with an arc plate 15, and the top of the arc plate 15 is provided with a first docking hole 16. The surface of the support plate 10 is provided with a slide groove 20, and the slide plate 22 is embedded in the slide groove 20. The rear end top of the slide plate 22 is integrally formed with a rear baffle plate 14, and the rear end of the slide plate 22 is welded with a first spring 21. The interior of the support plate 10 is provided with a heat dissipation fin groove 23, and the rear end of the front baffle plate 11 is welded with a guide rod 24, and the end of the guide rod 24 is embedded in the interior of the support plate 10. The bottom of the support plate 10 is integrally formed with a rotating sleeve 17, and the rotating sleeve 17 is sleeved on the surface of the support shaft 18. The surface of the front baffle 11 is welded with a handle 12, and the bottom of the front baffle 11 is provided with an exhaust hole 13. The end of the first spring 21 is welded and fixed to the inner wall end of the slide slot 20, and the exhaust hole 13 is aligned with the opening position of the heat sink fin slot 23. The independent battery module 9 is supported by the module support assembly 3, and the module support assembly 3 after placement will tilt toward the rear, and it is not necessary to lock it to ensure that the placed independent battery will not fall easily. When the placed independent battery module 9 is disassembled and assembled, the module support assembly 3 can also be pulled to assist the operation, so that the heavier independent battery module 9 can slide from a high place to a low place and then be taken out, making the disassembly and assembly process of the independent battery module 9 more labor-saving and convenient.

[0031] Specifically, when installing the independent battery module 9, the front baffle 11 of the module support assembly 3 is manually pulled outward. Since the front baffle 11 is heavier when the independent battery module 9 is not placed, the weight of the front end of the module support assembly 3 is greater than that of the rear end. The front end of the module support assembly 3 is in a downward pressed state, and the rear end is in an upward tilted state. After the front baffle 11 is pulled out, it can present a downward tilted state, such as Figure 2As shown, at this time, the independent battery module 9 is placed on the module support assembly 3, and the handle 12 is manually pushed, and the tension of the first spring 21 is cooperated to assist in pushing the placed independent battery module 9 onto the support plate 10. At this time, the module support assembly 3 is continued to be manually embedded into the interior of the independent energy storage frame 1 to complete the placement of the independent battery module 9. At this time, since the independent battery module 9 is placed and the support shaft 18 is located below the support plate 10 near the front end, the influence of the self-weight of the front baffle 11 is reduced, and the center of gravity of the module support assembly 3 moves backward, which eventually causes the rear end of the entire module support assembly 3 to be pressed down and the front end to be tilted.

[0032] In this embodiment, the independent energy storage frame 1 includes a side plate 5 and a plug-in plate 7. The bottom of the side plate 5 is integrally formed with a base 6. The front end of the base 6 is provided with a locking screw hole 8. The rear end of the base 6 is integrally formed with a plug-in plate 7. The top of the plug-in plate 7 is provided with a connecting notch 37. The rear end of the independent energy storage frame 1 is provided with a guide channel 38. The inner wall of the side plate 5 is provided with a second docking hole 39, and the guide channel 38 is partially connected with each second docking hole 39. The arc plate 15 is used to cover the surface of the second docking hole 39. After the arc plate 15 rotates around the support shaft 18, the first docking hole 16 and the second docking hole 39 are aligned and connected with each other. The module support assembly 3 is used to support each independent battery module 9, and the support assembly with the independent battery module 9 placed thereon will automatically open the connection state with the inside of the guide channel 38 at the rear of the independent energy storage frame 1, so that it can further ensure that the cooling airflow is only applied to the area where the independent battery module 9 is installed, thereby improving the utilization rate of the low-temperature airflow.

[0033] Specifically, when the independent energy storage frame 1 is pushed toward the rear end by the loading and unloading unit 4, the plug-in plate 7 will be pressed against the pressure plate 31, and the pressure plate 31 will move backward, so that the top closing plate 32 is removed from the inside of the diverter groove 36, and the closing plate 32 is embedded in the inside of the telescopic groove 35. At this time, the diverter groove 36 can be connected with the inside of the plug-in plate 7 through the connecting notch 37. Therefore, the low-temperature airflow flowing in the guide groove 34 can enter each second docking hole 39 along the connecting notch 37 and the guide channel 38. In the area of ​​the conveying channel 25 where the independent energy storage frame 1 is not plugged in, the pressure plate 31 is not subjected to pressure. Therefore, the closing plate 32 will always block the diverter groove 36 in this area to ensure that the low-temperature airflow can all flow into the independent energy storage frame 1 in the above-mentioned usage state.

[0034] After each module support assembly 3 is placed with an independent battery module 9, the rear end will move downward, so the arc plate 15 will move away from the surface of the second docking hole 39, and finally align the first docking hole 16 with the second docking hole 39. Therefore, the low-temperature airflow inside the guide channel 38 can enter the interior of the heat dissipation fin groove 23 along the first docking hole 16 and the second docking hole 39, and finally be discharged outward from the exhaust hole 13 at the front end. As for the module support assembly 3 without the independent battery module 9 placed therein, the rear end is tilted, so the arc plate 15 closes the second docking hole 39, so the low-temperature airflow will not enter the unused module support assembly 3.

[0035] In this embodiment, the cooling system 2 includes a delivery channel 25 and a cooling airflow pipe 26, the end of the cooling airflow pipe 26 is connected to an external refrigeration device, a guide groove 34 is provided inside the delivery channel 25, and the other end of the cooling airflow pipe 26 is connected to the inside of the guide groove 34. A diverter groove 36 is provided at the bottom of the diverter groove 34, and a telescopic groove 35 is provided on the inner wall of the diverter groove 36, and a closing plate 32 is inserted at the bottom of the diverter groove 36. A pressure plate 31 is integrally formed at the front end of the closing plate 32, and a second spring 33 is welded to the rear end of the pressure plate 31, and the rear end of the second spring 33 is fixedly connected to the inner wall of the diverter groove 36, and the rear end of the closing plate 32 is embedded in the interior of the telescopic groove 35, and the surface of the pressure plate 31 is flush with the surface of the delivery channel 25, and the length of the pressure plate 31 is the same as the width of the independent energy storage frame 1. The loading and unloading unit 4 includes a hydraulic rod 27 and a transmission plate 28. The two ends of the hydraulic rod 27 are fixedly connected to the conveying channel 25 and the surface of the transmission plate 28 by screws. A plurality of locking screws 29 are inserted in the middle of the transmission plate 28. A hand wheel 30 is welded at one end of each locking screw 29. The locking screw 29 is used to be inserted into the locking screw hole 8. Each independent energy storage frame 1 is pushed by the loading and unloading unit 4 to control whether it is docked with the cooling system 2 at the rear. Therefore, the cooling airflow can be automatically and centrally guided according to the number of independent energy storage frames 1 built through this structure, so that the cooling airflow can all enter the independent energy storage frame 1 in use, and the plugging and removal process of the independent energy storage frame 1 is more labor-saving and efficient.

[0036] Specifically, after turning the hand wheel 30 to embed the locking screw 29 into the locking screw hole 8, the hydraulic rod 27 is controlled to perform telescopic movement in this state, which can synchronously drive the independent energy storage frame 1 after the lock connection to perform translational movement, and then control whether the independent energy storage frame 1 embeds the rear end plug-in board 7 into the interior of the conveying channel 25, and thus directly control the area of ​​the independent energy storage frame 1 that the low-temperature airflow transported in the cooling system 2 can enter.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
