Description

Technical Field

[0001] The invention relates to the technical field of battery packs, in particular to a heat dissipation mechanism for a large industrial energy storage battery pack. Background Art

[0002] Large-scale industrial energy storage battery packs play a vital role in the field of modern energy storage. These systems usually contain a large number of battery cells, which will generate a lot of heat during the charging and discharging process. If this heat is not dissipated in a timely and effective manner, the internal temperature of the battery will rise, which will affect the battery's performance and life, and may even cause safety problems.

[0003] Battery heat dissipation technology, also known as thermal management cooling technology, is essentially a heat exchange process that transfers the heat inside the battery to the external environment through a cooling medium, thereby reducing the internal temperature of the battery.

[0004] However, in some large-scale industrial energy storage battery packs, it is difficult to quickly and effectively dissipate the heat inside the module by relying solely on natural cooling, which can easily cause heat accumulation and affect the cycle life of the battery cell. It is also impossible to automatically obtain the temperature inside the battery box to servo-start the heat dissipation mechanism, which will cause the heat dissipation mechanism to be always running, which is not energy-efficient and lacks effective mechanisms and protection mechanisms to stabilize the battery body.

Further, when the battery body 4 is placed into the body of the battery box 1, when the knob 73 is rotated, the bidirectional screw rod 72 is rotated in cooperation with the square plate 71. In addition, a T-shaped block 74 is threadedly installed on the outer side of the bidirectional screw rod 72, and a long groove 75 is provided on the rectangular bar 64.

A limiting rod 79 is fixedly installed between the two groups of square plates 71 located at the rear end of the battery body 4. The two groups of T-shaped blocks 74 located at the rear end of the battery body 4 are both slidably fitted on the outside of the limiting rod 79, so that the battery body 4 is placed more stably, so that the T-shaped block 74 moves, so that the cylinder 76 moves inside the long groove 75, and cooperates with the deformation of the inner spring 77 and the round rod 78, so that more battery bodies 4 of different sizes can be fixed in the center, and cooperates with the limiting rod 79 to make the fixing effect better, so that the left and right ends of the battery body 4 can be well fixed, and then the stability of the battery pack body can be further improved.

[0043] In one embodiment of the present invention, a protection assembly 8 is provided on the battery box 1, and the protection assembly 8 includes a rack 81.

The rack 81 meshes with the adjusting gear 84, and a controller 85 is fixedly installed on the outside of the long plate 82. The adjusting gear 84 makes the controller 85 in different gears through the short rod 83. Further, when the T-shaped block 74 moves, the rack 81 is driven to move synchronously, thereby cooperating with the long plate 82 and the adjusting gear 85. The gear 84 causes the short rod 83 to rotate to different amplitudes, thereby placing the controller 85 in different gears. A servo slide 86 is fixedly installed on the outside of the battery box 1, and the controller 85 is electrically connected to the servo slide 86. A baffle 87 is slidably installed inside the servo slide 86, and the side wall of the baffle 87 slides and fits the outer wall of the heat sink 57. There are two groups of servo slides 86 and baffles 87, so that the distance between the two groups of baffles 87 can be adjusted in coordination with the servo slide 86. When the number of battery bodies 4 is small, the distance is closer, thereby controlling the area blocked by the heat sink 57, thereby effectively preventing external dust from entering the battery box 1, and then better protecting the battery pack body.

[0044] Working principle: First, when the battery body 4 is working, it will generate heat, which will increase the temperature inside the battery box 1. Then, in cooperation with the fixing rod 58, the through slot 510 and the through hole 511, the expansion airbag 512 in the rectangular box 59 will expand due to the heat, so that the slide plate 513 will move, so that the slide bar 515 will slide inside the rectangular plate 514, and at the same time, the spring 516 will stretch and deform, so that the slide bar 515 will squeeze and resist the push switch 517, so that it can automatically sense whether the battery body 4 is running. When the push switch 517 is squeezed, the servo motor 51 will be started, so that the rotating shaft 52 The transmission assembly 53 rotates, and the rotating rod 55 on the inner side of the fixing frame 54 rotates synchronously, so that the fan blade 56 rotates, so that the heat inside the battery box 1 is discharged through the heat sink 57. When the temperature drops, the slide bar 515 will move away from the push switch 517, so that the push switch 517 automatically resets, so that the servo motor 51 stops running, which can better dissipate heat for the battery pack body while saving energy. Further, when the battery body 4 is placed inside the battery box 1, the rectangular bar 64 is cooperated to make the rectangular block 62 slide inside the rectangular tube 61, and the reset spring 63 The compression deformation can be achieved by utilizing the elastic potential energy of the return spring 63 to fix the front and rear ends of the battery body 4 well, thereby making the battery pack body more stably fixed. Furthermore, after the battery body 4 is placed inside the battery box 1, the knob 73 is turned to cooperate with the square plate 71 to rotate the bidirectional screw rod 72, thereby moving the T-shaped block 74, thereby moving the cylinder 76 inside the long groove 75, and cooperating with the deformation of the inner spring 77 and the round rod 78, more battery bodies 4 of different sizes can be fixed, and the limiting rod 79 can make the fixing effect better, thereby being able to fix the battery body 4 The left and right ends are well fixed, which can further improve the stability of the battery pack body. Furthermore, when the T-shaped block 74 moves, it drives the rack 81 to move synchronously, so that the long plate 82 and the adjustment gear 84 can make the short rod 83 rotate to different amplitudes, so that the controller 85 is in different gears, so that the distance between the two sets of baffles 87 can be adjusted in cooperation with the servo slide rail 86. When the battery body 4 is less, the distance is closer, so that the area blocked by the heat sink 57 can be controlled, thereby effectively preventing external dust from entering the battery box 1, and then better protecting the battery pack body.

[0045] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
