Description

Technical Field

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

[0002] With the rapid development of the new energy industry, energy storage systems are being used more and more widely in the industrial and commercial sectors. As a key piece of equipment in energy storage systems, industrial and commercial energy storage cabinets are mainly used to house and protect core components such as energy storage battery modules, high-voltage boxes, and energy storage converters.

[0003] Currently, existing industrial and commercial energy storage cabinets typically house multiple energy storage battery modules inside the cabinet. These modules generate a significant amount of heat during charging and discharging. Although existing energy storage cabinets generally employ forced air cooling, uneven air distribution often leads to localized heat accumulation and excessively large temperature differences within the battery clusters. Utility Model Content

[0004] The main purpose of this utility model is to provide an industrial and commercial energy storage cabinet to solve the above-mentioned technical problems.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] A commercial and industrial energy storage cabinet includes: a cabinet body, on the side of which a refrigeration device is disposed; a support frame disposed within the cabinet body; and a sealing plate disposed between the refrigeration device and the support frame. The sealing plate has a plurality of ventilation hole groups, each ventilation hole group including a plurality of ventilation holes distributed along the height direction of the sealing plate. The ventilation holes communicate with the interior of the cabinet body, allowing the cold air from the refrigeration device to be distributed to different height positions within the cabinet body through the ventilation holes.

[0007] The cabinet contains two battery compartments spaced apart on the left and right sides. The plurality of ventilation hole groups include: a first ventilation hole group located in the middle of the sealing plate for ventilation to the area between the two battery compartments; a second ventilation hole group located on the left side of the sealing plate for ventilation to the battery compartment on the left side; and a third ventilation hole group located on the right side of the sealing plate for ventilation to the battery compartment on the right side.

[0008] In this configuration, the ventilation holes in the first, second, and third ventilation hole groups are evenly spaced along the height direction of the sealing plate, and adjacent ventilation holes in the first, second, and third ventilation hole groups along the width direction of the sealing plate are positioned at the same horizontal height.

[0009] The device also includes a cover plate, which is disposed between the refrigeration device and the sealing plate. The cover plate has a through opening that communicates with the air outlet of the refrigeration device. The cover plate and the sealing plate form a cavity, which communicates with the opening and the ventilation hole respectively.

[0010] The cavity is equipped with an air guide plate, which is used to divert the cold air flowing out of the opening to each of the ventilation holes.

[0011] The air guide plate is located on the side of the cavity away from the opening.

[0012] The air guide plate includes a first guide plate, a second guide plate, a third guide plate, and a fourth guide plate. The first and second guide plates are distributed vertically along the height of the sealing plate and are located in front of the opening to guide part of the cold air to the first ventilation hole group. The third guide plate is located on the left side of the opening and is used to guide part of the cold air to the third ventilation hole group. The fourth guide plate is located on the right side of the opening and is used to guide part of the cold air to the second ventilation hole group.

[0013] The air guide plate is disposed opposite to the first ventilation hole group, and the air guide plate is provided with a through hole, which is connected to a portion of the ventilation holes in the first ventilation hole group.

[0014] The battery compartment contains multiple energy storage battery modules arranged along its height, and an energy storage converter and a high-voltage box are located at the bottom of the battery compartment.

[0015] The beneficial technical effects of this utility model are as follows: By setting a sealing plate with multiple ventilation hole groups between the refrigeration device and the support frame, wherein each ventilation hole group includes multiple ventilation holes distributed along the height direction, the cold air generated by the refrigeration device can reach different height positions inside the cabinet through these distributed ventilation holes, thereby achieving uniform distribution of cold air inside the cabinet, effectively solving the problem of local heat accumulation in the prior art and reducing the temperature difference between batteries in the cluster.

Detailed Implementation

[0024] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0025] like Figures 1-6 As shown, the industrial and commercial energy storage cabinet provided in this embodiment includes: a cabinet body 100, a refrigeration device 300 disposed on the side of the cabinet body 100; a support frame 200 disposed inside the cabinet body 100; and a sealing plate 400 disposed between the refrigeration device 300 and the support frame 200. A plurality of ventilation hole groups 410 are provided through the sealing plate 400. Each ventilation hole group 410 includes a plurality of ventilation holes 411 distributed along the height direction of the sealing plate 400. The ventilation holes 411 are connected to the interior of the cabinet body 100 so that the cold air from the refrigeration device 300 can be distributed to different height positions inside the cabinet body 100 through the ventilation holes 411.

[0026] In this embodiment, the cabinet 100 includes a rear door panel 110, left and right side panels, and a front door panel (not shown in the attached drawings), used to house and protect the various internal components of the energy storage cabinet. A support frame 200 is installed inside the cabinet 100 to support and fix the various functional modules of the energy storage cabinet. The side where the rear door panel 110 is located is the rear side of the cabinet 100. A cooling device 300 is vertically fixed to the rear side (back) of the cabinet 100, and it has an air outlet (not shown in the attached drawings), specifically a cold air outlet. The cooling device 300 can be an industrial air conditioner or other equipment with cooling functions, used to cool the various functional modules inside the cabinet 100.

[0027] A sealing plate 400 is installed between the refrigeration unit 300 and the support frame 200. The sealing plate 400 primarily serves to physically separate the refrigeration unit 300 from the support frame 200. The sealing plate 400 is a plate-like structure that covers the rear side of the support frame 200. Multiple ventilation hole groups 410 are provided through the sealing plate 400. Each ventilation hole group 410 includes multiple ventilation holes 411 distributed along the height direction of the sealing plate 400. The ventilation holes 411 connect to the internal space of the cabinet 100, thus forming a cooling path. This design allows cold air to be evenly distributed at different height positions within the cabinet 100. When the refrigeration unit 300 is operating, cold air enters the cabinet 100 through the ventilation hole groups 410, cooling the various functional modules within the cabinet 100. This design improves cooling uniformity.

[0028] In one embodiment, the cabinet 100 is provided with two battery compartments 500 spaced apart from each other on the left and right. The plurality of ventilation hole groups 410 include: a first ventilation hole group 411a disposed in the middle of the sealing plate 400 for ventilation to the area between the two battery compartments 500; a second ventilation hole group 411b disposed on the left side of the sealing plate 400 for ventilation to the left battery compartment 500; and a third ventilation hole group 411c disposed on the right side of the sealing plate 400 for ventilation to the right battery compartment 500.

[0029] In this embodiment, as Figure 3 and Figure 4 As shown, two battery compartments 500 are symmetrically arranged on the support frame 200 for installing and fixing energy storage battery modules. This left-right distribution helps to achieve a centrally balanced center of gravity for the energy storage cabinet, and also facilitates group management and maintenance of the energy storage battery modules.

[0030] Multiple ventilation hole groups 410 are divided into three groups according to their orientation: a first ventilation hole group 411a facing the space between the two battery compartments 500, a second ventilation hole group 411b facing the left side of the left battery compartment 500, and a third ventilation hole group 411c facing the right side of the right battery compartment 500. This grouping arrangement design ensures that cold air can cool the battery compartments 500 from multiple directions, effectively improving the cooling effect inside the cabinet 100. Specifically, the first ventilation hole group 411a is mainly used to cool the area between the two battery compartments 500, while the second and third ventilation hole groups 411b and 411c are responsible for cooling the left and right battery compartments 500 respectively. This multi-directional distribution of cooling airflow effectively avoids the problem of localized heat accumulation inside the cabinet 100.

[0031] In one embodiment, the ventilation holes 411 in the first ventilation hole group 411a, the second ventilation hole group 411b, and the third ventilation hole group 411c are all evenly spaced along the height direction of the sealing plate 400, and the ventilation holes 411 adjacent to each other in the first ventilation hole group 411a, the second ventilation hole group 411b, and the third ventilation hole group 411c along the width direction of the sealing plate 400 are arranged at the same horizontal height.

[0032] In this embodiment, as Figure 3 and Figure 4 As shown, the first ventilation hole group 411a, the second ventilation hole group 411b, and the third ventilation hole group 411c each have multiple ventilation holes 411 arranged along the height direction of the sealing plate 400. The ventilation holes 411 in each ventilation hole group 410 are distributed along the height direction at a preset equal interval to ensure that the cold air can be evenly distributed at different heights within the cabinet 100.

[0033] Specifically, the first ventilation hole group 411a is arranged in the middle area of ​​the sealing plate 400, the second ventilation hole group 411b is arranged in the left side area of ​​the sealing plate 400, and the third ventilation hole group 411c is arranged in the right side area of ​​the sealing plate 400. In the width direction of the sealing plate 400, when the first ventilation hole group 411a is adjacent to the second ventilation hole group 411b, or when the first ventilation hole group 411a is adjacent to the third ventilation hole group 411c, the adjacent ventilation holes 411 are all located at the same horizontal height. This arrangement allows the ventilation holes 411 of each ventilation hole group 410 to form multiple horizontal ventilation layers, which is beneficial for forming a stable airflow path for cold air within the cabinet 100, thereby improving the cooling effect.

[0034] This embodiment sets multiple evenly distributed ventilation holes 411 on the sealing plate 400 and keeps adjacent ventilation holes 411 at the same horizontal height in the width direction, forming a regular airflow path. This ensures that the cold air can reach different heights inside the cabinet 100 and makes the airflow distribution more uniform and orderly, effectively improving the cooling effect inside the cabinet 100.

[0035] In one embodiment, a cover plate 600 is also included. The cover plate 600 is disposed between the refrigeration device 300 and the sealing plate 400. An opening 610 is provided through the cover plate 600 and communicates with the air outlet of the refrigeration device 300. The cover plate 600 and the sealing plate 400 form a cavity 620, which communicates with the opening 610 and the ventilation hole 411 respectively.

[0036] In this embodiment, as Figure 5 and Figure 6As shown, a cover plate 600 is also provided between the refrigeration device 300 and the sealing plate 400. The cover plate 600 is made of metal sheet and is used to cooperate with the sealing plate 400 to guide the cold air generated by the refrigeration device 300. The opening 610 on the cover plate 600 is connected to the air outlet of the refrigeration device 300. With this design, the cold air generated by the refrigeration device 300 can enter the cavity 620 through the opening 610.

[0037] A cavity 620 communicating with the opening 610 is formed between the cover plate 600 and the sealing plate 400. This cavity 620 serves as a collection space for cold air, receiving cold air from the cooling unit 300. Together with the ventilation hole group 410 on the sealing plate 400, it forms a guiding channel, achieving a reasonable distribution of cold air to each ventilation hole 411. This design not only improves cooling efficiency but also makes the cold air distribution more uniform.

[0038] In one specific embodiment, the cavity 620 is a cuboid-shaped space.

[0039] In one embodiment, a guide vane 630 is provided inside the cavity 620, which is used to divert the cold air flowing out of the opening 610 to each ventilation hole 411.

[0040] In this embodiment, as Figure 5 and Figure 6 As shown, a guide vane 630 is provided inside the cavity 620. The main function of the guide vane 630 is to guide the cold air from the opening 610, directing it towards the ventilation hole 411 in a preset direction. Through the guiding effect of the guide vane 630, the flow direction of the cold air can be better controlled, avoiding turbulence in the cavity 620, reducing flow resistance and energy loss, and improving cooling efficiency.

[0041] In one embodiment, the air guide plate 630 is disposed inside the cavity 620 on the side away from the opening 610.

[0042] In this embodiment, as Figure 5 and Figure 6 As shown, from the perspective of facing the rear door panel 110, the air guide plate 630 and the opening 610 are distributed in a front-to-back manner within the cavity 620. This arrangement causes the cold air flowing out of the opening 610 to be blocked and its flow direction changed by the air guide plate 630, thereby achieving a more reasonable airflow distribution.

[0043] In one embodiment, the air guide plate 630 includes a first guide plate 631, a second guide plate 632, a third guide plate 633, and a fourth guide plate 634; the first guide plate 631 and the second guide plate 632 are distributed vertically along the height direction of the sealing plate 400 and are located in front of the opening 610, for guiding part of the cold air to the first ventilation hole group; the third guide plate is located on the left side of the opening 610, for guiding part of the cold air to the third ventilation hole group; and the fourth guide plate is located on the right side of the opening 610, for guiding part of the cold air to the second ventilation hole group.

[0044] In this embodiment, as Figure 5 and Figure 6 As shown, the first guide plate 631 and the second guide plate 632 are located in front of the opening 610 and are arranged vertically to guide part of the cold air flow to the first ventilation hole group 411a, so that the cold air can enter the area between the two battery compartments 500. Specifically, the first guide plate 631 and the second guide plate 632 are directly arranged on the first ventilation hole group 411a. The third guide plate 633, located on the left side of the opening 610, is used to guide part of the cold air to the third ventilation hole group 411c to cool the right battery compartment 500; the fourth guide plate 634, located on the right side of the opening 610, is used to guide part of the cold air to the second ventilation hole group 411b to cool the left battery compartment 500. Through this arrangement of the air guide plates 630, the cold air can be reasonably distributed to ensure that all areas inside the cabinet 100 are effectively cooled.

[0045] The left and right battery compartments 500 are shown from the perspective of facing the front door panel (not shown in the attached diagram, but positioned opposite the rear door panel 110). The front, left, and right sides of the opening 610 are shown from the perspective of facing the rear door panel 110.

[0046] The angles of each guide plate can be adjusted according to the airflow path requirements, and can generally be set to an angle of 15°-45° with the vertical plane. This multi-plate combination air guiding structure improves the uniformity of cold air distribution and avoids turbulence when cold air blows into the cavity 620.

[0047] In one embodiment, the air guide plate 630 is disposed opposite to the first ventilation hole group 411a, and the air guide plate 630 is provided with a through hole 635, which communicates with a portion of the ventilation holes 411 of the first ventilation hole group 411a.

[0048] In this embodiment, as Figure 5 and Figure 6As shown, the air guide plate 630 is disposed on the first ventilation hole group 411a, and a through hole 635 is provided through the air guide plate 630. The through hole 635 communicates with some of the ventilation holes 411 of the first ventilation hole group 411a. This design allows some cold air to directly enter the area between the battery compartments 500 through the through hole 635, while the remaining cold air flows to other areas by the guidance of the air guide plate 630.

[0049] In one embodiment, a plurality of energy storage battery modules 510 are arranged in the battery compartment 500 along the height direction, and an energy storage converter 520 and a high voltage box 530 are arranged at the bottom of the battery compartment 500.

[0050] In this embodiment, as Figure 1 and Figure 2 As shown, these energy storage battery modules 510 are modularly arranged in an array within the cabinet 100. Specifically, there are two rows of energy storage battery modules 510, with at least 3-4 modules 510 in each row. An energy storage converter 520 and a high-voltage box 530 are located at the bottom of one of the battery compartments 500. The energy storage converter 520 is used to realize bidirectional energy conversion of the energy storage system. The high-voltage box 530 contains high-voltage electrical components, including but not limited to circuit breakers, contactors, and other protective devices. Positioning the energy storage converter 520 and the high-voltage box 530 at the bottom of the battery compartment 500 not only facilitates cooling but also lowers the overall center of gravity of the energy storage cabinet, improving its overall stability.

[0051] In summary, this embodiment of the invention, by setting a sealing plate 400 between the cooling device 300 and the supporting frame 200, and setting multiple ventilation hole groups 410 on the sealing plate 400, allows the cold air generated by the cooling device 300 to be distributed to different height positions within the cabinet 100 through the ventilation holes 411. Simultaneously, by setting a cover plate 600 and the sealing plate 400 to form a cavity 620, and arranging multiple air guide plates 630 within the cavity 620, directional distribution of cold air is achieved. The rational arrangement of the multiple ventilation hole groups 410, combined with the guiding effect of the air guide plates 630, allows the cold air to simultaneously cover the area between the battery compartments 500 and the left and right battery compartments 500, forming a complete cooling channel. Furthermore, the through holes 635 further optimize the flow path of the cold air, allowing some cold air to directly enter the target area, effectively increasing the flow path of the cold air. This multi-layered cooling structure not only improves the overall cooling efficiency of the energy storage cabinet but also effectively avoids local heat accumulation, ensuring the stable operation of the energy storage battery module 510 during charging and discharging. Meanwhile, by arranging the energy storage converter 520 and the high-voltage box 530 at the bottom of the battery compartment 500, cooling is facilitated and the center of gravity of the energy storage cabinet is lowered, improving the overall structural stability. This structural design solves the problem of uneven cooling in existing technologies, improving the cooling performance and operational reliability of industrial and commercial energy storage cabinets.

[0052] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
