Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to an energy storage battery box. Background Technology

[0002] Energy storage battery enclosures are battery structures that integrate multiple small batteries through stacking. This compact arrangement of batteries increases the load density of the enclosure, allowing for greater energy supply while reducing space requirements. However, existing energy storage battery enclosures generally rely on bottom-level natural heat dissipation. For layered stacked enclosures, heat accumulation occurs between layers, leading to significant temperature differences between batteries and reducing the lifespan of batteries in the warmer areas. Furthermore, the heat dissipation effect of energy storage battery enclosures is greatly affected by environmental factors. Higher external temperatures worsen heat dissipation, causing some batteries to operate at reduced power due to the high temperatures, thus reducing the overall operating power of the battery enclosure and impacting its usability.

[0003] Therefore, how to improve the operational safety and stability of energy storage battery boxes is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an energy storage battery housing with high operational safety and strong operational stability.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An energy storage battery housing, comprising:

[0007] A carrier module, wherein a plurality of the carrier modules are stacked along a first direction, and a plurality of battery cells are disposed within a single carrier module;

[0008] The heat dissipation fins and heat dissipation ducts are provided. The heat dissipation fins are fixedly disposed on one outer wall surface of the support module in the second direction. The heat dissipation ducts are fixedly connected to the outer wall of the support module and surround the heat dissipation fins. The heat dissipation ducts cover at least a portion of the side wall of the support module in the third direction and open on both sides in the first direction. The first direction, the second direction and the third direction are perpendicular to each other, and the second direction is the width direction of the support module.

[0009] A fan module is disposed on either side of the support module in the first direction, and the outflow direction of the fan module covers the opening of the heat dissipation duct in the first direction to blow airflow in the multiple sets of heat dissipation ducts along the first direction.

[0010] Preferably, in the above-mentioned energy storage battery housing, the air outlet of the fan module is provided with a guide frame, one side of the guide frame is attached to the outer wall surface of the supporting module in the first direction, and communicates with the opening of the heat dissipation duct.

[0026] The core of this utility model lies in disclosing an energy storage battery housing with high operational safety and strong operational stability.

[0027] To enable those skilled in the art to better understand the present invention, embodiments of the present invention will be described below with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the invention as described in the claims. Additionally, the complete contents of the configurations shown in the following embodiments are not limited to those necessary for the solution of the invention as described in the claims.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the energy storage battery housing provided in this embodiment mainly includes a support module 10, heat dissipation fins 20, heat dissipation ducts 30, and a fan module 40. Several support modules 10 are provided, and these support modules 10 are stacked along a first direction. It should be noted that the first direction is typically the vertical direction of the energy storage battery housing when it is placed. Figure 1 In the Z direction, the stacked arrangement of the support modules 10 refers to the complete overlap of the projections of two adjacent support modules 10 in the first direction. Several support modules 10 stacked and fitted together constitute the structure of the energy storage battery box. Each support module 10 contains multiple battery cells 110, forming a modular structure based on the support module 10. The energy storage battery box selects an appropriate number of support modules 10 for stacking and assembly according to capacity and functional requirements to meet usage needs. The modular support modules 10 are also easy to disassemble and assemble, enabling convenient expansion of functional requirements.

[0029] Based on this, the heat dissipation fins 20 are fixedly disposed on the outer wall of one side of the support module 10 in the second direction. It should be noted that the second direction is the width direction of the support module 10. Figure 1 In the Y direction, the outer wall surface of the carrier module 10 in the second direction has a larger wall area, thereby allowing for the provision of larger heat dissipation fins 20 to assist in heat dissipation of the battery cell 110 inside the carrier module 10. One section of the heat dissipation fin 20 is fixedly disposed on the outer wall of the carrier module 10 to carry away the heat generated by the battery cell 110 inside the carrier module 10 through heat conduction. Correspondingly, the heat dissipation duct 30 is a channel structure fixed to the outer wall surface of the carrier module 10. The heat dissipation duct 30 is preferably a U-shaped structure and is snapped onto the outer wall surface of the carrier module 10, and the channel formed by it and the carrier module 10 surrounds the heat dissipation fins 20. It should be noted that the heat dissipation duct 30 is used to provide an airflow path to assist in heat dissipation of the carrier module 10. The heat dissipation duct 30 covers at least a portion of the side wall of the carrier module 10 in the third direction and has openings on both sides in the first direction to form a duct structure, thereby optimizing heat dissipation of the covered portion of the side wall of the carrier module 10. It should also be noted that the third direction is the length direction of the carrier module 10, i.e. Figure 1The X direction. In the above structure, the first direction, the second direction, and the third direction are mutually perpendicular, i.e. Figure 1 The X, Y, and Z directions are adjusted to give the carrier module 10 a more regular, easier-to-manufacture, transport, and disassemble cuboid structure.

[0030] Correspondingly, to ensure the heat dissipation requirements of the support module 10 under any operating condition, the energy storage battery housing is equipped with a fan module 40 to drive airflow. Specifically, the fan module 40 is positioned on either side of the support module 10 in the first direction. That is, the stacked support modules 10 are first assembled into a single structure, and then the fan module 40 is positioned on at least one side of this single structure. Simultaneously, the fan's outflow direction at least covers the opening of the heat dissipation duct 30 in the first direction. It should be noted that while several support modules 10 are stacked in the first direction, the heat dissipation ducts 30 are connected end-to-end to form an airflow channel in the first direction. The fan module 40 can drive airflow along the first direction, passing through the airflow channel formed by multiple heat dissipation ducts 30, and carrying away the heat transferred by the heat dissipation teeth 20 within the heat dissipation ducts 30. This achieves heat dissipation of the support module 10, reduces the operating temperature of the battery cells 110 within the support module 10, and improves the lifespan and operating efficiency of the battery cells 110.

[0031] The energy storage battery housing provided in this embodiment features a modular support module 10 for supporting the battery cells 110, while also facilitating easy disassembly and assembly for quick functional expansion. Multiple heat dissipation fins 20 are fixedly mounted on the side wall of the support module 10 to dissipate heat generated by the battery cells 110 during operation. Correspondingly, the energy storage battery housing also includes a heat dissipation duct 30 and a fan module 40. The heat dissipation duct 30 is fixedly mounted on the outer wall of the support module 10. When the support modules 10 are stacked along a first direction, the heat dissipation ducts 30 are connected end-to-end to form an airflow channel in the first direction, simultaneously shielding and protecting the heat dissipation fins 20 to prevent external dust and debris from adhering and affecting their heat dissipation effect. The fan module 40 blows airflow along the first direction through the airflow channel formed by the multiple heat dissipation ducts 30, accelerating the airflow velocity around the heat dissipation fins 20 in the airflow channel, satisfying the heat dissipation needs of the heat dissipation fins 20 and the support module 10, thereby improving the operational safety and stability of the energy storage battery housing.

[0032] Furthermore, to reduce the airflow loss of the fan module 40 and improve the airflow effect of the fan module 40 on the area surrounding the heat dissipation fins 20, this embodiment provides a guide frame 50 in the air outlet area of ​​the fan module 40. One side of the guide frame 50 is connected to the air outlet in the first direction, and the other side is attached to the outer wall surface of the support module 10 in the first direction to form a diffusion structure. At the same time, since the outer wall surface of the support module 10 in the first direction is a closed structure, the side of the guide frame 50 that is attached to the support module 10 will only communicate with the opening of the heat dissipation duct 30. Correspondingly, all the airflow from the fan module 40 will pass through the heat dissipation duct 30 due to the guiding effect of the guide frame 50, so that it can be fully utilized for the heat dissipation and cooling needs of the heat dissipation fins 20.

[0033] Furthermore, it should be noted that the heat dissipation denticles 20 on one side of the support module 10 in the second direction can improve the heat dissipation effect of the internal battery cell 110 during operation. In a preferred embodiment of this utility model, heat dissipation denticles 20 are provided on both outer walls of the support module 10 in the second direction. That is, the heat dissipation denticles 20 on the two outer walls of the support module 10 respectively undertake part of the heat dissipation requirements to help achieve heat dissipation of the internal battery cell 110. Correspondingly, each heat dissipation denticle 20 on each side of the support module 10 in the second direction is provided with a corresponding heat dissipation air duct 30. Providing heat dissipation denticles 20 on the two opposite side walls of the support module 10 can also improve the structural uniformity of the support module 10 and improve its stability during installation.

[0034] Based on the above embodiments, in a single carrier module 10, the internally disposed battery cells 110 are arranged in a rectangular array to present a uniform row and column structure inside the carrier module 10. Simultaneously, the rectangular array arrangement of the battery cells 110 ensures that the number of battery cells 110 disposed between the central plane and the outer walls on both sides in the second direction is similar or equal. This results in similar heat generation from the battery cells 110 on both outer walls, allowing the heat dissipation fins 20 on both sides of the carrier module 10 to operate with similar heat generation, reducing the risk of excessive heat generation and heat dissipation difficulties in one side of the heat dissipation fin area, and improving the overall heat dissipation effect of the carrier module 10.

[0035] To further optimize the above technical solution, in this embodiment, the battery cells 110 are arranged in one or two rows along the second direction, i.e., the width direction of the support module 10, within the support module 10, while at least one column of battery cells 110 is arranged along the third direction, i.e., the length direction of the support module 10. Specifically, since heat dissipation teeth 20 are provided on both outer walls of the support module 10 in the second direction, the heat generated by the battery cells 110 arranged close to the outer walls of the support module 10 in the second direction can be transferred to the wall more quickly and discharged by the heat dissipation teeth 20. Therefore, the heat generated by the battery cells 110 arranged in one or two rows along the second direction under the action of the heat dissipation teeth 20 on both sides can be quickly discharged and carried away by the airflow blown out by the fan module 40. If there are two or more rows of battery cells 110, the presence of other battery cells 110 blocking the middle section of the battery cells 110 from the sidewall of the supporting module 10 will create heat shielding. This will prevent the heat generated by the middle section of the battery cells 110 from being transferred to the sidewall and heat dissipation fins 20 in a timely manner, thus causing the temperature of the supporting module 10 to rise and affecting the stable operation of the energy storage battery box. The arrangement of at least one row of battery cells 110 along a third direction is to ensure that the number of battery cells 110 within the supporting module 10 meets the energy storage and power supply requirements of the energy storage battery box.

[0036] To further improve the heat dissipation effect of the battery cells 110 within the carrier module 10, in this embodiment, in the third direction, the arrangement of the battery cells 110 within the carrier module 10 is all within the projection range of the heat dissipation duct 30, so that the heat dissipation of the battery cells 110 can be achieved within the effective range of the heat dissipation duct 30. It should be noted that the projection range of the heat dissipation duct 30 is the area covered by the projection of the heat dissipation duct 30 on the side wall of the battery cell 110 facing the heat dissipation duct 30, which can ensure that the battery cells 110 are all located in the airflow path blown out by the fan module 40, thereby improving their heat dissipation effect. At the same time, the heat dissipation teeth 20 are also set to fill the projection range of the heat dissipation duct 30. Specifically, this means that the heat dissipation duct 30 is set within the projection of the side wall of the carrier module 10 where the heat dissipation teeth 20 are set, and multiple heat dissipation teeth 20 are evenly arranged, so as to achieve a rapid heat dissipation effect on the battery cells 110 located within the projection range of the heat dissipation duct 30.

[0037] Furthermore, in this embodiment, the heat dissipation denticles 20 provided on the outer wall of the energy storage battery box can be configured as plate-like structures perpendicular to the outer wall of the supporting module 10, i.e., common heat dissipation plates. Preferably, adjacent heat dissipation denticles 20 are arranged in parallel to have the same spacing, thus achieving a uniform heat dissipation effect. In other embodiments, the heat dissipation denticles 20 can also be wave-shaped and uniformly arranged along a third direction. The wave-shaped structure can increase the surface area of ​​the heat dissipation denticles 20 while maintaining a certain thickness of the heat dissipation duct 30, thereby improving its heat transfer effect. At the same time, under the blowing effect of the fan module 40, the heat dissipation denticles 20 can have a larger airflow contact area, thereby accelerating its heat dissipation effect and improving the operational stability of the supporting module 10.

[0038] It should also be noted that the heat dissipation teeth 20 are preferably made of copper or aluminum to ensure good heat transfer and conduct heat to the battery cell 110.

[0039] Furthermore, in this embodiment, in order to ensure the operating effect of the fan module 40, it is preferable to arrange two fan modules 40 at intervals in the third direction. The two fan modules 40 can provide sufficient air volume and can also serve as backups for each other, so that when a single fan fails, the energy storage battery box can still achieve the blowing function of the fan module 40 to meet the heat dissipation requirements.

[0040] Considering the ease of assembly of the carrier module 10, in this embodiment, as... Figure 4 As shown, the heat dissipation duct 30 has a U-shaped structure, and the two sides of the heat dissipation duct 30 in the third direction are extended thin sliding plates 310. Correspondingly, the support module 10 has a corresponding sliding groove 120. The heat dissipation duct 30 slides relative to the support module 10 in the first direction, so that the sliding plates 310 slide into the sliding groove 120 in the first direction, thereby realizing the pre-installation of the heat dissipation duct 30 on the support module 10. At the same time, the heat dissipation duct 30 is fixed to the support module 10 by bolts. The above structure enables quick assembly of the heat dissipation duct 30 through the sliding structure, and the bolts maintain the fixing effect of the heat dissipation duct 30. The operation of adding or removing the support module 10 of the energy storage battery box is convenient, thereby improving the operation convenience of the energy storage battery box.
