[0024] The following is in conjunction with the appendix Figures 1 to 8 The present invention will be described in further detail, but this is not intended to limit the invention.

[0025] like Figure 1 and 2 As shown, in one embodiment of the present invention, the energy storage battery includes a housing 100, a first thermally conductive limiting component 200, a second thermally conductive limiting component 300, a battery assembly 400, and a heat extraction component 500. The first thermally conductive limiting component 200 and the second thermally conductive limiting component 300 are arranged side by side and are both connected to the interior of the housing 100. A first cavity 101, a third cavity 103, and a second cavity 102 are sequentially connected between the first thermally conductive limiting component 200 and the housing 100, respectively. A circulation through hole 110 is provided inside the housing 100. The two ends of the circulation through hole 110 are respectively connected to the first cavity 101 and the exterior of the housing 100. The battery assembly 400 is disposed inside the third cavity 103. The heat extraction component 500 is connected to the housing 100. The input end and the output end of the heat extraction component 500 are respectively connected to the second cavity 102 and the exterior of the housing 100.

[0026] The technical solution of this invention employs a first thermally conductive limiting component, a second thermally conductive limiting component, and a housing to form three sequentially connected and independent spaces: a first cavity, a third cavity, and a second cavity. This achieves the safety and protection of independent assembly of the battery module. Furthermore, the suction function of the heat extraction component guides the heat exchange airflow through the circulating through-holes sequentially through the first cavity, the third cavity, and the second cavity. This allows for heat extraction from the side of the battery module not facing the heat extraction component, the interior of the battery module, and the side of the battery module facing the heat extraction component. This helps reduce the uneven heat distribution within the battery module, thereby increasing the coverage area for heat conduction and dissipation, and improving the safety and stability of its use.

[0027] Specifically, in some implementations, such as Figure 1 and 2 As shown, the heat extraction component 500 includes a mounting plate 510 and a heat extraction fan 520 connected to the mounting plate 510; the heat extraction fan 520 is connected in communication with the second chamber 102. The mounting plate 510 is detachably connected to the housing 100 by screws or bolts to ensure smooth and stable heat extraction.

[0028] Specifically, in some implementations, such as Figure 1 and 2 As shown, the battery assembly 400 includes at least two clamping and mounting components 420 and a battery component 410 connected between the clamping and mounting components 420; and the two ends of the clamping and mounting components 420 respectively abut against the first thermally conductive limiting component 200 and the second thermally conductive limiting component 300; the two ends of the battery component 410 respectively abut against the first thermally conductive limiting component 200 and the second thermally conductive limiting component 300. As shown in Figure 2, there are two clamping and mounting components 420, which are symmetrically connected inside the housing 100. This structure, through the battery component 410 and its clamping and limiting clamping mounting components, ensures the assembly stability of the battery component 410 and achieves a separation effect between the housing 100 and its exterior, thereby improving the protection performance of the internal battery component 410. In addition, the two ends of the clamping mounting component 420 abut against the first thermally conductive limiting component 200 and the second thermally conductive limiting component 300, respectively, to achieve rapid heat transfer from the battery component 410 to the clamping mounting component 420. Combined with the fact that the two ends of the battery component 410 abut against the first thermally conductive limiting component 200 and the second thermally conductive limiting component 300, respectively, to achieve rapid heat transfer from the battery component 410, the speed and effect of heat dissipation are improved.

[0030] Specifically, in some implementations, such as Figure 1 and 5 As shown, the projection of the first heat-conducting channel 221 toward the first flow-guiding channel 413 at least partially overlaps with the first flow-guiding channel 413; the projection of the second heat-conducting channel 323 toward the first flow-guiding channel 413 at least partially overlaps with the first flow-guiding channel 413. In some embodiments, the projection of the first heat-conducting channel 221 toward the first flow-guiding channel 413 completely overlaps with the first flow-guiding channel 413; the projection of the second heat-conducting channel 323 toward the first flow-guiding channel 413 completely overlaps with the first flow-guiding channel 413. This structure, with its sequentially overlapping heat-conducting channels 221, 413, and 323, improves the orderliness and smoothness of heat flow, thereby helping to maintain the uniformity of heat distribution within the battery assembly 410, and ultimately improving the stability and safety of its use.

[0031] Specifically, in some implementations, such as Figure 2 As shown, the second thermally conductive limiting component 300 includes a thermally conductive vent plate 320 and a thermally insulating sealing plate 310 connected to at least one end of the thermally conductive vent plate 320; the thermally insulating sealing plate 310 is disposed between the thermally conductive vent plate 320 and the housing 100; the second thermally conductive channel 323 is disposed inside the thermally conductive vent plate 320. There are two thermally insulating sealing plates 310, symmetrically connected to the upper and lower ends of the thermally conductive vent plate 320; and the thermally insulating sealing plates 310 abut against the housing 100 to achieve the function of separating the heat of the housing 100, and to allow the heat of the battery component 410 to be extracted and discharged as evenly as possible along the thermally conductive vent plate 320 and its second thermally conductive channel 323, thereby improving the uniformity of heat distribution inside the battery component 410, and thus improving the stability and safety of use. Of course, the assembly method, materials, and other factors of the thermally insulating sealing plate 310 can be selected according to conventional techniques in the art, and are not limited here.

This structure, through the U-shaped or C-shaped structure formed by the second horizontal section 424, the first horizontal section 423, and the supporting longitudinal section 422, combined with the first thermally conductive limiting component 200 and the second thermally conductive limiting component 300 at the other two ends, achieves the circumferential assembly of the battery component 410; thereby ensuring assembly stability while improving heat dissipation.

The outer heat insulation layer and the inner heat conduction layer each have a supporting longitudinal section 422 and a second horizontal section 424 and a first horizontal section 423 connected to one side surface of the supporting longitudinal section 422; and the diameter direction of the second flow channel 415 is perpendicular to the diameter direction of the first flow channel 413; so that some of the horizontal heat is discharged from the clamping and mounting components 420 at both ends and their third flow channel and second heat conduction channel 323; and the heat insulation effect of the outer heat insulation layer avoids the influence of external heat on the battery component 410, thereby helping to improve the uniformity of heat inside the battery component 410 as much as possible, thereby improving the stability and safety of use.

[0036] Specifically, in some implementations, such as Figure 1 and 6 As shown, the battery component 410 includes a locking frame 411, at least two battery bodies 412, and at least one connecting assembly 414; the locking frame 411 has at least one locking groove 4111; each battery body 412 is connected to the interior of a corresponding locking groove 4111; the connecting assembly 414 is connected to two adjacent battery bodies 412; and an intersecting first flow channel 413 and a second flow channel 415 are formed between two adjacent battery bodies 412.
