Description

Technical Field

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

[0002] An energy storage combiner cabinet is a power device used to integrate multiple energy storage units. It plays an important role in new energy power generation systems and grid management systems. As a key link in power conversion and distribution, its performance and heat dissipation methods have a decisive impact on the stability and security of the entire system.

[0003] Utility model patent CN 222072553 U discloses an energy storage combiner cabinet. This cabinet uses natural airflow to drive rotating blades, which in turn drive a four-bladed fan to rotate synchronously, thus preventing heat accumulation inside the cabinet and maintaining airflow. In addition, a temperature sensor is installed to detect the internal temperature of the cabinet. When the temperature is too high, the fan assembly is activated to absorb and expel heat from both sides of the battery and controller, aiming to ensure effective heat dissipation while reducing energy consumption. However, although this design helps improve heat dissipation, its energy-saving effect is limited. Furthermore, due to the limited size of the fan assembly inside the cabinet, efficient heat dissipation cannot be achieved. Therefore, under high-temperature environments or high-load operating conditions, the internal temperature of the cabinet may still be too high, affecting the normal operation and lifespan of the equipment.

[0004] Therefore, given the shortcomings of existing technologies, we urgently need an energy storage combiner cabinet to solve this problem. This combiner cabinet should significantly improve heat dissipation efficiency and energy consumption control, while better meeting the needs of modern power systems and providing strong support for the sustainable development of new energy applications and grid management. Utility Model Content

[0005] The purpose of this utility model is to provide an energy storage combiner cabinet that solves the problem that its energy consumption reduction effect is limited, and that due to the limited size of the fan assembly inside the cabinet, it cannot achieve efficient heat dissipation, resulting in the cabinet's internal temperature still being too high under high temperature or high load conditions, which affects the normal operation and service life of the equipment.

[0006] To achieve the above objectives, this utility model provides an energy storage combiner cabinet, comprising a bottom mounting base, a top mounting base, and a cabinet body;

[0007] The cabinet is mounted on top of the bottom mounting base, and the top mounting base is mounted on top of the cabinet and connected to the top of the bottom mounting base via a support plate;

[0008] The top and bottom of the cabinet are provided with ventilation slots that communicate with the interior of the cabinet. Fans are installed inside the bottom mounting base and the top mounting base respectively. The two ventilation slots are respectively connected to two fans.

[0009] Both sides of the cabinet are detachably connected to side mounting plates that are connected to the support plate.

[0010] The bottom mounting base has support legs fixedly connected to the four corners of its bottom, and a dust filter structure that works with the fan is installed at the center of its bottom.

[0011] The top end of the support plate is fixedly connected to the bottom of the top mounting base with bolts, and the bottom end of the support plate is fixedly connected to the top of the bottom mounting base.

[0012] The dust filtration structure includes a mounting ring fixedly connected to the bottom of the bottom mounting base and a filter plate fixedly connected to the bottom of the mounting ring by bolts.

[0013] One end of the side mounting plate is fixedly connected to a fixing plate, and one side of the fixing plate is bolted to the side wall of the support plate.

[0014] The cabinet has a telescopic connecting cover at the top. The top of the telescopic connecting cover is connected to the bottom of the top mounting base via a mounting ring plate, and the bottom is connected to the top of the cabinet via a mounting ring plate.

[0015] This utility model discloses an energy storage combiner cabinet that achieves a more efficient forced ventilation cooling mechanism through fans installed in the bottom and top mounting bases. This not only overcomes the problem of low heat dissipation efficiency caused by the limited size of the fan assembly, but also allows for the use of more powerful fans, further improving heat dissipation efficiency and ensuring that the cabinet interior remains within a suitable operating temperature range even under high-temperature environments or high-load operating conditions. Furthermore, the rational design of the ventilation slots' position and size ensures smoother airflow, reducing energy loss and improving energy utilization efficiency. The removable design of the side mounting plates simplifies maintenance, reduces downtime, and lowers operating costs. Attached Figure Description

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Example 1

[0025] Please see Figure 1-5 As shown, an energy storage combiner cabinet of this embodiment includes a bottom mounting base 1, a top mounting base 3, and a cabinet body 2. The cabinet body 2 is located on top of the bottom mounting base 1, and the top mounting base 3 is located on top of the cabinet body 2 and connected to the top of the bottom mounting base 1 through a support plate 13. Ventilation slots 6 communicating with the interior of the cabinet body 2 are provided on both the top and bottom of the cabinet body 2. Fans 9 are installed inside both the bottom mounting base 1 and the top mounting base 3, and the two ventilation slots 6 are respectively connected to two fans 9. Side mounting plates 4 connected to the support plate 13 can be detachably connected to both sides of the cabinet body 2.

[0026] The energy storage combiner cabinet's operation begins with the bottom mounting base 1 and the top mounting base 3. These two parts not only support the cabinet body 2 but also house the internal fan 9. During operation, the fan 9 in the bottom mounting base 1 acts as an air intake device, drawing cooler outside air into the cabinet body 2 through the bottom ventilation slot 6. This cool air, once inside the cabinet, flows along a pre-defined path, carrying away heat generated by the battery pack, controller, and other heat-generating components. Simultaneously, the fan 9 in the top mounting base 3 acts as an exhaust device, expelling the heated air from the cabinet through the top ventilation slot 6, forming a complete air circulation system. The detachable connection between the side mounting plate 4 and the support plate 13 facilitates equipment maintenance and repair. The entire process ensures continuous airflow within the cabinet, effectively reducing the internal temperature.

[0027] Example 2

[0028] Please see Figure 1-5As shown in this embodiment, an energy storage combiner cabinet has support legs 5 fixedly connected to the four corners of the bottom of the bottom mounting base 1. A dust filter structure that cooperates with a fan 9 is installed at the center of the bottom of the bottom mounting base 1. Specifically, through the support legs 5 fixedly connected to the four corners of the bottom of the bottom mounting base 1 and the dust filter structure that cooperates with the fan 9 installed at the center of the bottom, the support legs 5 provide a stable foundation for the entire energy storage combiner cabinet during operation. At the same time, the filter plate 12 in the dust filter structure filters the air entering the bottom mounting base 1, preventing external dust from entering the cabinet 2. This achieves the effect of improving the overall stability of the equipment, reducing the impact of the external environment on the electrical components inside the cabinet, thereby extending the service life of the equipment and ensuring its long-term stable operation.

[0029] The dust filtration structure includes a mounting ring 11 fixedly connected to the bottom of the bottom mounting base 1 and a filter plate 12 bolted to the bottom of the mounting ring 11. Specifically, through the mounting ring 11 and the filter plate 12 fixedly connected to the bottom of the mounting ring 11, during operation, when the fan 9 in the bottom mounting base 1 operates as an air intake device, air is filtered through the filter plate 12 to remove dust particles before entering the cabinet. This effectively prevents dust from entering the cabinet and contaminating electrical components, further improving the equipment's reliability and heat dissipation efficiency.

[0030] Example 3

[0031] Please see Figure 1-5 As shown in this embodiment, in an energy storage combiner cabinet, the top end of the support plate 13 is fixedly connected to the bottom of the top mounting base 3 with bolts, and the bottom end of the support plate 13 is fixedly connected to the top of the bottom mounting base 1. Specifically, through the design of fixing the top end of the support plate 13 to the bottom of the top mounting base 3 with bolts, and fixing the bottom end of the support plate 13 to the top of the bottom mounting base 1, the support plate 13 not only serves to connect the top mounting base 3 and the bottom mounting base 1 during operation, but also enhances the overall structural rigidity, ensuring that the cabinet 2 remains stable under high load operation or frequent maintenance. This achieves the effect of enhancing the overall structural strength, simplifying the maintenance process, and reducing the risk of failure due to structural loosening.

[0032] A fixing plate 10 is fixedly connected to one end of the side mounting plate 4. One side of the fixing plate 10 is bolted to the side wall of the support plate 13. Specifically, the design of the fixing plate 10 fixedly connected to one end of the side mounting plate 4 and the bolted connection between the fixing plate 10 and the side wall of the support plate 13 allows for quick disassembly of the side mounting plate 4 during operation, facilitating easy access for personnel to inspect or repair the cabinet interior. This simplifies maintenance operations, reduces downtime, and improves system availability and efficiency.

[0033] A telescopic connecting cover 8 is installed on the top of cabinet 2. The top of the telescopic connecting cover 8 is connected to the bottom of the top mounting base 3 via a mounting ring plate 7, and the bottom is connected to the top of cabinet 2 via a mounting ring plate 7. Specifically, through the telescopic connecting cover 8 on the top of cabinet 2, the top of which is connected to the bottom of the top mounting base 3 via a mounting ring plate 7, and the bottom of which is connected to the top of cabinet 2 via a mounting ring plate 7, the telescopic connecting cover 8 achieves a flexible connection between cabinet 2 and top mounting base 3 during operation, allowing for a certain amount of displacement between them to adapt to installation requirements in different environments. This achieves the effect of protecting internal components from external vibration or displacement, while ensuring smooth airflow between ventilation slot 6 and fan 9, further improving heat dissipation efficiency and equipment durability.

[0034] This solution includes the following workflow:

[0035] The energy storage combiner cabinet's operation begins with the bottom mounting base 1 and the top mounting base 3. These two parts not only support the cabinet body 2 but also house the internal fan 9. During operation, the fan 9 in the bottom mounting base 1 acts as an air intake device, drawing in cooler outside air into the cabinet body 2 through the bottom ventilation slot 6. This cool air, once inside the cabinet, flows along a pre-defined path, carrying away the heat generated by the battery pack, controller, and other heat-generating components. Simultaneously, the fan 9 in the top mounting base 3 acts as an exhaust device, expelling the heated air from the cabinet through the top ventilation slot 6, forming a complete air circulation system. During this process, the support legs 5, which are fixedly connected to the four corners of the bottom mounting base 1, provide a stable foundation for the entire energy storage combiner cabinet, preventing the equipment from tipping over or the structure from loosening due to uneven ground or external vibrations. Simultaneously, the dust filtration structure installed at the center of the bottom, in conjunction with the fan 9, includes a mounting ring 11 fixedly connected to the bottom of the bottom mounting base 1 and a filter plate 12 bolted to the bottom of the mounting ring 11. This effectively filters dust particles from the air entering the cabinet, preventing external dust from contaminating the electrical components inside the cabinet. The design of the top end of the support plate 13 being bolted to the bottom of the top mounting base 3 and the bottom end being bolted to the top of the bottom mounting base 1 enhances the overall structural robustness, ensuring the cabinet 2 remains stable even under high load operation or frequent maintenance. The design of the side mounting plate 4, with a fixing plate 10 fixedly connected to one end and a bolted connection between one side of the fixing plate 10 and the side wall of the support plate 13, enables the side mounting plate 4 to be detachable, allowing staff to quickly remove it for inspection or maintenance inside the cabinet. In addition, the telescopic connecting cover 8 set on the top of the cabinet 2 is designed to connect the top to the bottom of the top mounting base 3 through the mounting ring plate 7 and the bottom to the top of the cabinet 2 through the mounting ring plate 7. This design realizes a flexible connection between the cabinet 2 and the top mounting base 3, allowing for a certain displacement margin between the two, adapting to the installation needs in different environments, and ensuring smooth airflow between the ventilation slot 6 and the fan 9.

[0036] The beneficial effects of this energy storage combiner cabinet are reflected in several aspects: The support legs 5, which are fixedly connected to the four corners of the bottom mounting base 1, and the dust filter structure installed at the bottom center in conjunction with the fan 9, improve the overall stability of the equipment and reduce the impact of the external environment on the electrical components inside the cabinet, thereby extending the service life of the equipment and ensuring its long-term stable operation; the design of the top part of the support plate 13 being fixedly connected to the bottom of the top mounting base 3 with bolts, and the bottom end being fixedly connected to the top of the bottom mounting base 1, enhances the overall structural strength, simplifies the maintenance process, and reduces the risk of failure due to structural loosening; the dust filter structure includes a mounting ring 11 fixedly connected to the bottom of the bottom mounting base 1 and bolts... The filter plate 12 attached to the bottom of the mounting ring 11 effectively prevents dust from entering the cabinet and contaminating electrical components, further improving the reliability and heat dissipation efficiency of the equipment. The design of fixing plate 10 fixedly connected to one end of the side mounting plate 4 and fixing plate 10 to the side wall of support plate 13 with bolts on one side simplifies maintenance operations, shortens downtime, and improves system availability and work efficiency. The telescopic connecting cover 8 set on the top of the cabinet 2 and the design of the top and bottom connected to the top mounting base 3 and the cabinet 2 respectively through the mounting ring plate 7 protect the internal components from external vibration or displacement, while ensuring smooth airflow between the ventilation slot 6 and the fan 9, further improving heat dissipation efficiency and equipment durability.
