Description

Technical Field

[0001] This application relates to the field of battery cabinet technology, specifically to an energy storage cabinet, and further to an energy storage system including the energy storage cabinet. Background Technology

[0002] An energy storage cabinet is a device used to store and release electrical energy. Its working principle is based on an electrochemical reaction. When there is a surplus of electricity, the energy storage cabinet converts the excess electrical energy into chemical energy and stores it in batteries. When energy demand increases, the energy storage cabinet converts the stored chemical energy into electrical energy and supplies it to the power grid or other equipment.

[0003] To maintain the batteries within a reasonable temperature range and ensure their normal operation, air conditioners are typically installed in energy storage cabinets to cool them. Currently, when installing air conditioners for heat dissipation in energy storage cabinets, a wall-mounted method is generally used, placing the air conditioner externally on the outside of the cabinet. A drain hole is created at the bottom of the air conditioner to allow condensate to drain. This installation method is unsightly because the air conditioner protrudes outwards and occupies external space in the energy storage cabinet. Another method is to integrate the air conditioner inside the cabinet, leaving a gap at the bottom of the cabinet door for drainage. While this solves the aesthetic problem from the outside, the condensate generated by the air conditioner flows down the inner wall of the cabinet door, leaving watermarks on the inner wall of the door panel over time, which is detrimental to long-term maintenance and upkeep. Furthermore, this installation method results in poor sealing between the cabinet door and the bottom of the cabinet, making it difficult to meet the sealing requirements of energy storage cabinets. Utility Model Content

[0022] In addition to one or more of the above, or as an alternative, in another embodiment, the air conditioning component is embedded inside the mounting housing and communicates with the airflow through the deflector window, and the bottom of the air conditioning component has a condensate outlet communicating with the deflector.

[0023] In addition to one or more of the above, or as an alternative, in another embodiment, the mounting housing includes:

[0024] Multiple mounting plates are configured to be fixedly arranged around the periphery of the flow guide window, and the flow guide opening is opened in one of the mounting plates located below the flow guide window.

[0025] In addition to one or more of the above, or as an alternative, in another embodiment, the mounting plate located below the flow guide window is inclined relative to the door body, and the flow guide opening is located at the bottommost position of the mounting plate near the door body.

[0031] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting an installation shell inside the cabinet, it is convenient to install the air conditioning component on the inner wall of the door, thereby embedding it inside the energy storage cabinet to improve the external aesthetics of the energy storage cabinet; by using the guide channel set inside the door, the door structure itself can be used as a flow channel for condensate; and the bottom of the installation shell has a guide port that communicates with the guide channel, so that the condensate generated by the air conditioning component inside the installation shell can be discharged after flowing through the guide port and the guide channel to the bottom of the door, realizing the concealed discharge of internal air conditioning condensate. Moreover, because the guide channel formed by the internal structure of the door is used, the sealing component attached to the inner wall of the door can be staggered with the outlet of the guide channel, so it will not affect the installation of the sealing component on the door, thus effectively ensuring the sealed connection between the cabinet door and the cabinet, which can meet the sealing level requirements of the energy storage cabinet.

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0044] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0045] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0046] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0048] In existing technologies, air conditioners are typically installed on the outer wall of the energy storage cabinet door. However, this arrangement affects the aesthetics of the energy storage cabinet. If the air conditioner is installed on the inner wall of the cabinet door, the drainage of internal condensate needs to be considered. If the condensate is drained directly along the outer wall of the cabinet door, scale will easily form on the outer wall of the cabinet over time, which also makes it difficult to solve the aesthetic problem. If the condensate is diverted to the inner wall of the cabinet door or a drainage pipe is installed inside, there will be interference with the sealing strip on the cabinet door, making it difficult to guarantee the sealing between the cabinet door and the cabinet body, and failing to meet the sealing level requirements of the energy storage cabinet. This application is proposed to address the above technical problems.

[0049] Figure 1This is a perspective view of an energy storage cabinet according to one embodiment of the present application. The energy storage cabinet can be used in an energy storage system and includes: a cabinet body 1, a door body 2 connected to the cabinet body 1, and further includes: a mounting housing 3 installed inside the door body 2 and configured to have a flow guide port 31 formed at the bottom; an air conditioning component 4 embedded inside the mounting housing 3 and communicating with external airflow; a flow guide channel 5 formed inside the door body 2; and a sealing member 6 fitted between the inner wall of the door body 2 and the cabinet body 1. The air conditioning component 4 is configured to have its condensate outlet connected to the flow guide port 31; the flow guide channel 5 is constructed to be hollow inside and its top end connected to the flow guide port 31, and the flow guide channel 5 extends from the flow guide port 31 to the bottom surface of the door body 2 and communicates with the outside; the sealing member 6 is configured to seal and fill the gap at the connection between the door body 2 and the cabinet body 1.

[0050] Under this arrangement, refer to Figures 1-5 The energy storage cabinet described in this article features an installation shell 3 inside the cabinet body 1, which facilitates the installation of the air conditioning component 4 on the inner wall of the door body 2, thus integrating it inside the energy storage cabinet to enhance its external aesthetics. A flow channel 5 inside the door body 2 allows the door body 2 itself to act as a condensate drainage channel. A flow port 31, connected to the flow channel 5, is formed at the bottom of the installation shell 3, allowing the condensate generated by the air conditioning component 4 inside the installation shell 3 to flow through the flow port 31 and the flow channel 5 and then drain from the bottom of the door body 2, achieving concealed drainage of internal air conditioning condensate. Furthermore, the flow channel 5 formed by the internal structure of the door body 2 allows the sealing component 6, which is attached to the inner wall of the door body 2, to be misaligned with the outlet of the flow channel 5, thus not affecting the installation of the sealing component 6 on the door body 2. This effectively ensures a sealed connection between the cabinet door and the cabinet body 1, meeting the sealing requirements of the energy storage cabinet.

[0051] It is easy to see that this application modifies the structure of the door 2 itself, so that the external structure of the cabinet door itself is not changed. The sealing component 6 is installed using the original cabinet door structure. Condensate flows out from the bottom of the door 2 along the guide channel 5. Therefore, the guide channel 5 will not interfere with the installation position of the sealing component 6. While realizing the concealed discharge of condensate, it effectively ensures the connection and sealing between the door 2 and the cabinet 1.

[0052] For example, the aforementioned flow channel 5 can be formed using the structure of the door body 2 itself, or a flow channel can be filled and installed inside the door body 2. As long as the aforementioned flow channel 5 is formed inside the door body 2, the specific setting method is not a limiting provision of this embodiment.

[0053] The following will illustrate further specific implementations or refinements of the board enclosure assembly through exemplary description, in order to further improve it or for other improvement considerations.

[0054] Based on this, refer to Figure 2 The door body 2 includes: a support frame 21 configured to form the flow channel 5 inside, and an inner plate 22 and an outer plate 23 configured to be spaced apart on the inner and outer sides of the support frame 21.

[0055] It can be seen that by setting the flow channel 5 inside the support frame 21, the flow channel 5 can be formed by the structure of the door body 2 itself. This not only ensures the structural strength of the door body 2 itself, but also eliminates the need to add other components to achieve built-in drainage of condensate. The structure is simple and the production cost of the cabinet door is reduced.

[0056] It is easy to see that, since this embodiment does not require the installation of other guide pipes or other covering components on the inner wall of the door 2, the guide channel 5 is located directly inside the door 2. Therefore, while ensuring the aesthetics of the cabinet door interior, it avoids occupying too much space inside the cabinet 1, providing a structural basis for placing other components inside the cabinet 1, thus having strong practicality.

[0057] In one embodiment, the support frame 21 includes: an outer frame 211 configured to surround the outer periphery of the inner plate 22; a transverse frame 212 extending horizontally and connected to the inner side of the outer frame 211; and a flow guide frame 213 extending vertically and connected to the outer frame 211 and the transverse frame 212. One end of the flow guide frame 213 is connected to the flow guide port 31, and the other end away from the flow guide port 31 extends beyond the bottom surface of the outer frame 211 by a certain length. The flow guide channel 5 is formed through the interior of the flow guide frame 213.

[0058] It can be known that, for reference Figure 2 , Figure 3 , Figure 4 and Figure 5 The outer frame 211 facilitates the formation of the main support structure of the door body 2, while the horizontal frame 212 extends horizontally to support the interior of the outer frame 211, and the guide frame 213 can support the interior of the outer frame 211 vertically, thereby improving the structural strength of the door body 2.

[0059] Based on this, refer to Figure 5 The flow guide frame 213 has a through-type flow guide channel 5, which facilitates the formation of the flow guide channel 5 using the structure of the support frame 21 itself, thereby realizing multiple uses of the support frame 21. In addition, the end of the flow guide frame 213 opposite to the flow guide port 31 extends beyond the bottom surface of the outer frame 211. Figure 5 It can also be seen that the end of the guide frame 213 extends beyond the outer frame 211 by a certain length and is connected to the outside. This ensures that the guide channel 5 can extend beyond the bottom surface of the outer frame 211 and be connected to the outside, so as to discharge the condensate to the outside of the door 2.

[0060] For example, the aforementioned flow guide frame 213 can be a square skeleton with a square cross-section, or a circular skeleton, or a shell structure with other cross-sectional shapes. The specific cross-sectional shape can be selected as needed, and this embodiment does not make specific limitations here.

[0061] In another embodiment, reference is made to... Figure 4 and Figure 5 The door body 2 also includes an insulation layer 24 configured to fill the space between the inner panel 22 and the outer panel 23.

[0062] It can be seen that by filling the interior of the door body 2 with an insulation layer 24, the insulation effect on the inside and outside of the door body 2 is improved, the insulation performance of the door body 2 is enhanced, and a thermal insulation basis is provided for the thermal management of the air conditioner.

[0063] For example, the above-mentioned insulation layer 24 can be a polystyrene foam, rock wool board, glass wool, fiber cotton and other insulation materials. By utilizing its good thermal insulation and fire resistance, the door body 2 can be thermally insulated. Of course, the above-mentioned insulation layer 24 can also be other materials. This embodiment does not make specific limitations here.

[0064] In actual operation, this embodiment should be referred to Figure 3 The sealing member 6 is configured as a sealing strip and is fixedly attached to the inner wall of the outer frame 211 near the cabinet 1.

[0065] It is easy to see that by setting the sealing component 6 as a sealing strip, it is convenient to seal the gap between the door 2 and the cabinet 1. The sealing strip is fixedly attached to the inner wall of the outer frame 211, which facilitates the installation of the sealing strip by using the outer frame 211 to support it, and also facilitates the sealing between the door 2 and the cabinet 1 from the outer frame 211 inward.

[0066] For example, the material of the sealing strip can be rubber, polyvinyl chloride, natural rubber, thermoplastic elastomer, foam material, etc., so as to achieve a sealed connection at the junction of the door 2 and the cabinet 1. Of course, the sealing strip can also be other sealing materials, but this embodiment does not make specific limitations here.

[0067] In one embodiment, reference is made to... Figure 1 The energy storage cabinet also includes a flow guide window 7 located at the position opposite to the air conditioning component 4 on the outer panel 23, and the flow guide window 7 is configured to communicate with the outside airflow.

[0068] It can be seen that by using the air guide window 7 set on the door 2 and opposite to the air conditioning component 4, it is easy to communicate with the outside airflow, so that the air conditioning component 4 can communicate with the outside airflow channel during external circulation, which facilitates exhaust and ventilation.

[0069] Based on this, refer to Figure 2 , Figure 6 and Figure 7 The air conditioning component 4 is embedded inside the mounting housing 3 and communicates with the outside airflow through the air guide window 7. The bottom of the air conditioning component 4 has a condensate outlet that communicates with the air guide port 31.

[0070] It is easy to see that by embedding the air conditioning component 4 inside the mounting housing 3, its stable operation is ensured. The condensate outlet at the bottom of the air conditioning component 4 is connected to the guide port 31, which also facilitates the timely discharge of the condensate generated by the air conditioning component 4 through the guide port 31 and the guide channel 5, thus ensuring the normal operation of the air conditioning component 4.

[0071] For example, the air conditioning component 4 can also be directly installed on the inner wall of the door 2, and the airflow can be connected to the outside air by using the air guide window 7 on the door 2. As long as the condensate outlet of the air conditioning component 4 is connected to the air guide channel 5, the specific installation method of the air conditioning component 4 is not a limiting provision of this embodiment.

[0072] In another scenario of this embodiment, reference is made. Figure 2 , Figure 6 and Figure 7 The mounting housing 3 includes a plurality of mounting plates 32, which are configured to be fixed to the inner wall of the outer plate 23 and surround the periphery of the flow guide window 7. The flow guide port 31 is opened in one of the mounting plates 32 located below the flow guide window 7.

[0073] It is easy to see that by setting the above-mentioned mounting housing 3 into a structure of multiple mounting plates 32 spliced ​​together, it is easy to install it around the air guide window 7. The air guide port 31 is opened on one of the mounting plates 32 located below the air guide window 7, so that the condensate generated by the air conditioning component 4 inside the mounting housing 3 during operation can be discharged in time by using the air guide port 31.

[0074] Based on this, one of the mounting plates 32 located below the flow guide window 7 is inclined downward in the direction toward the outer plate 23, and the flow guide 31 is opened at the bottommost position of the mounting plate 32 near the door 2.

[0075] It is easy to see that by installing the mounting plate 32 located below the air guide window 7 at an angle relative to the door 2, and setting the air guide port 31 at the bottom position, the condensate water generated by the air conditioning component 4 can be discharged into the air guide port 31 in a timely manner through the mounting plate 32, thereby achieving rapid discharge of condensate water.

[0076] Furthermore, the flow guide window 7 has multiple flow guide mesh holes extending through it along the thickness direction, and the lowest flow guide mesh hole extends vertically above the flow guide opening 31 by a certain distance.

[0077] Specifically, since the mounting plate 32 is located below the deflector window 7, and the deflector window 7 is provided with multiple deflector mesh holes, when the deflector port 31 is blocked by debris, the condensate above the mounting plate 32 can be discharged through the aforementioned deflector mesh holes, which is convenient to adapt to extreme scenarios and meet the condensate discharge requirements of the air conditioning component 4.

[0078] It should be noted that the lowest point of the guide mesh extends vertically above the guide port 31 by a certain distance, ensuring that condensate will only flow out of the guide port 31 if it is not blocked, thus enhancing the reliability of internal condensate drainage.

[0079] For example, the aforementioned mounting plate 32 may be four air conditioner mounting brackets that surround the air guide window 7 and are connected to each other, while the air guide port 31 is opened on the lowest air conditioner mounting bracket. The air conditioner component 4 is embedded inside the mounting housing 3 formed by splicing the aforementioned air conditioner mounting brackets, and the four outer edges of the air conditioner component 4 are fitted and connected to the outer wall of the aforementioned air conditioner mounting brackets to achieve effective fixation of the air conditioner component 4 and the mounting housing 3.

[0080] Of course, the aforementioned mounting housing 3 can also be made of four mounting plates 32 in one piece. The specific arrangement is not a limiting provision of this embodiment.

[0081] In addition, air guide nets are provided on the side of the air conditioning component 4 near the air guide window 7 and the side near the cabinet 1. By utilizing its own internal and external circulation, it can achieve gas exchange with the outside world while ensuring the airtightness between itself and the cabinet 1.

[0082] It should be noted that the air conditioning component 4 is an air circulation device, including components such as a compressor, condenser, evaporator, and expansion valve, which are built into the mounting housing 3 and are connected to the airflow through the guide window 7 and the cabinet 1 on both sides respectively. By utilizing its own air circulation, it can regulate the temperature inside the cabinet 1. Of course, the air conditioning component 4 can also be other types of cooling and heating devices, but this embodiment does not make specific limitations here.

[0083] In another embodiment, the system further includes a dehumidification unit 8 fixedly installed on the inner wall of the door 2, and a support frame 9 disposed at the bottom of the cabinet 1 near the door 2 and configured to fit against the sealing member 6. The dehumidification unit 8 is configured such that its liquid outlet is connected to the flow channel 5.

[0084] It can be seen that the dehumidification unit 8 facilitates dehumidification of the interior of the cabinet 1, and the liquid outlet of the dehumidification unit 8 is connected to the guide channel 5, so that the liquid collected during the dehumidification process can be discharged from the cabinet 1 in a timely manner through the guide channel 5; while the support bracket 9 set at the bottom of the cabinet 1 near the door 2 can cooperate with the sealing component 6 to achieve a sealed connection between the bottom of the cabinet 1 and the door 2, providing a structural basis for its installation.

[0085] For example, the dehumidification unit 8 can be a dehumidifier, which is connected to the flow channel 5 through a drain pipe. Of course, the dehumidification unit 8 can also be other dehumidification mechanisms, which are not specifically limited in this embodiment.

[0086] In actual operation, the door 2 is configured to be rotatably connected to the cabinet 1 via a hinge.

[0087] For example, the door 2 can also be connected to the cabinet 1 by other structures. Of course, the door 2 can also be directly fixed to the cabinet 1. Therefore, the connection method between the cabinet 1 and the door 2 is not a limiting provision of this embodiment.

[0088] This embodiment also discloses an energy storage system, including a battery pack, a battery management unit, and an energy storage cabinet as described above.

[0089] It can be seen that by setting the aforementioned energy storage cabinet inside the energy storage system, and by setting an installation shell 3 inside the cabinet 1, it is convenient to install the air conditioning component 4 on the inner wall of the door 2, thereby embedding it inside the energy storage cabinet to improve the external aesthetics of the energy storage cabinet; by using the guide channel 5 set inside the door 2, the structure of the door 2 itself can be used as a flow channel for condensate; and the bottom of the installation shell 3 has a guide port 31 that communicates with the guide channel 5, so that the condensate generated by the air conditioning component 4 located inside the installation shell 3 can flow through the guide port 31 and the guide channel 5 and then be discharged after passing through the bottom of the door 2, realizing the concealed discharge of internal air conditioning condensate. Moreover, because the guide channel 5 formed by the internal structure of the door 2 is used, the sealing component 6 attached to the inner wall of the door 2 can be misaligned with the outlet of the guide channel 5, so it will not affect the installation of the sealing component 6 on the door 2, thereby effectively ensuring the sealed connection between the door 2 and the cabinet 1, which can meet the sealing level requirements of the energy storage cabinet and achieve the sealing effect of the energy storage system.

[0090] The above examples primarily illustrate the energy storage cabinet and the energy storage system including the cabinet of this application. Although only some embodiments of this application have been described, those skilled in the art should understand that this application can be implemented in many other forms without departing from its spirit and scope. Therefore, the examples and embodiments shown are considered illustrative rather than restrictive, and this application may cover various modifications and substitutions without departing from the spirit and scope of the technical solution of this application.
