Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air conditioning unit for an energy storage container and an energy storage container. Background Technology

[0002] The energy storage industry is developing rapidly, and the country is strongly supporting the modular construction of energy storage. Modular energy storage containers have been recognized and accepted by the energy storage industry. Through the modular design of energy storage containers, they can be placed in any desired location.

[0003] Energy storage containers house built-in lithium-ion battery energy storage devices. These containers can store electricity generated by wind power or during off-peak hours at night, allowing for use during peak daytime demand. This achieves energy savings and reduces electricity costs. The operating environment of the lithium-ion batteries within the container significantly impacts their performance. Therefore, to ensure the reliability of the operating environment and improve the overall reliability of the energy storage container, air conditioning equipment needs to be installed.

[0004] The installation methods for conventional energy storage container air conditioning units are mainly internal side-mounted and external external-mounted. When using the external external-mounted method, the air conditioning unit is also installed on the side of the container. Both of these installation methods require a lot of internal or external space in the energy storage container, resulting in low space utilization and a large footprint, which is not conducive to the efficient use of the energy storage container. Utility Model Content

[0005] The main technical problem solved by this utility model is to provide an air conditioning unit for an energy storage container, which is installed on the top of the container without occupying the internal and external space of the energy storage container, and has good waterproof performance to ensure the safe and reliable operation of the air conditioning unit. At the same time, it also provides an energy storage container in which the air conditioning unit for the energy storage container is installed.

[0006] To solve the above-mentioned technical problems, the basic concept of the first technical solution adopted by this utility model is as follows:

[0007] An air conditioning unit for an energy storage container is provided. The air conditioning unit is installed on the top plate of the container. An air supply vent and a return vent are provided on the bottom plate of the air conditioning unit shell. A first air vent and a second air vent are provided on the top plate of the container corresponding to the air supply vent and the return vent. An upwardly protruding waterproof platform is provided around the first air vent and the second air vent respectively. The air supply vent and the return vent are connected to the corresponding waterproof platform and a sealing ring is installed in the middle. An upwardly protruding mounting platform is also provided on the top plate. The bottom plate and the mounting platform are fixedly connected by fasteners.

[0008] Further, the cross-section of the waterproof platform is an inverted L-shaped structure bent outward or a C-shaped structure, and the upper surface of the waterproof platform is an installation plane对接 with the bottom plate of the housing, and a ring of the sealing ring is installed between the installation plane and the bottom plate.

[0009] Further, a ring of convex protrusions is provided around the air supply port and the air return port, and a ring of downward concave grooves is correspondingly provided on the installation plane of the waterproof platform. After installation, the protrusions and the sealing rings at the corresponding positions are pressed into the grooves together.

[0010] Further, at least two installation platforms extending along the length direction of the housing of the air conditioner unit are provided on the top plate of the container, and the first air outlet and the second air outlet are placed between the two installation platforms.

[0011] Further, the installation platform is installed on the top plate of the container in a closed ring shape.

[0012] Further, the installation platform is a mouth-shaped beam or a "ji"-shaped beam, the installation platform is welded to the top plate, and a maintenance port is provided at the position corresponding to the connection point of the fastener on the outer side edge of the installation platform.

[0013] Further, a first cavity and a second cavity are separated in the housing along the length direction of the air conditioner unit, a middle condensation cavity and two evaporation cavities on both sides are separated in the first cavity along the width direction of the air conditioner unit, a compressor assembly and an electric control box are installed in the second cavity, an air supply port is opened on the bottom plate of the housing of the evaporation cavity, and an air return port is provided between the two air supply ports.

[0014] Further, an air return port is provided directly below the condensation cavity, a horizontal partition board and two inclined partition boards are provided above the air return port, the horizontal partition board and the two inclined partition boards separate the condensation cavity above, and the space below the horizontal partition board is communicated with the evaporation cavities on both sides to guide the air entering from the air return port to the evaporation cavities on both sides.

[0015] Further, a condensation fan is installed in the condensation cavity, and a set of condensers is provided on each side of the condensation fan, and the condensers are installed obliquely in the condensation cavity.

[0016] The basic concept of the second technical solution adopted by the present utility model is:

[0017] An energy storage container, and the above-mentioned container air conditioner unit is installed above the top plate of the energy storage container.

[0018] In summary, compared with the prior art, the air conditioner unit for an energy storage container and the energy storage container provided by the present utility model have the following advantages:

[0019] (1) This utility model installs the air conditioning unit on the top plate of the container, so that the air conditioning unit does not need to occupy the space inside and outside the energy storage container. This effectively solves the problem that the traditional air conditioning unit is installed inside the energy storage container and externally attached to the side of the container, which makes the air conditioning unit occupy a large space. This improves the utilization rate of the container's internal space and reduces the container's floor area.

[0020] (2) This utility model connects the waterproof platform with the bottom plate of the air conditioning unit housing by setting an upward protrusion at the first air outlet and the second air outlet, raising the sealing position between the first air outlet and the second air outlet on the container to a height higher than the surface of the top plate, and using the height difference for waterproofing. At the same time, a sealing ring is also set between the waterproof platform and the bottom plate, realizing a double waterproof effect at the air outlet connection, which greatly improves the sealing and waterproof performance of the top-mounted air conditioning unit and the container at the air outlet connection, ensuring the safe and reliable operation of all components inside the container.

[0021] (3) The internal structure layout of the air conditioning unit of this utility model is more reasonable, making the structure more compact. Under the premise of meeting the cooling and heating performance of the air conditioning unit, it is conducive to reducing the height of the air conditioning unit and realizing the ultra-thin design of the air conditioning unit. This can further reduce the space occupied by the container as a whole.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] like Figure 1 As shown, this embodiment provides an air conditioning unit for an energy storage container. The air conditioning unit 1 is installed entirely above the top plate 2a of the container 2. In this way, the air conditioning unit 1 does not need to occupy the space inside or on the outside of the energy storage container 2, effectively solving the problem that the traditional air conditioning unit 1 is installed inside the energy storage container 2 or externally mounted on the side of the container 2, resulting in a large space occupation. This improves the utilization rate of the internal space of the container 2 and reduces the footprint of the container 2.

[0036] like Figure 2 and Figure 3 As shown, in this embodiment, a first cavity 3 and a second cavity 4 are separated within the casing of the air conditioning unit 1 along its length using a partition. The first cavity 3 and the second cavity 4 are arranged side by side. Within the first cavity 3, a condensing cavity 5 is further separated into two evaporating cavities 6 on either side along the width of the air conditioning unit 1 using a partition. A condensing fan 7 and a condenser 8 are installed in the condensing cavity 5. An evaporator 9 and a blower 10 are installed in each evaporating cavity 6. Preferably, the condensing fan 7, condenser 8, evaporator 9, and blower 10 are arranged along the length of the air conditioning unit 1. A compressor assembly 11 and an electrical control box 12 are installed in the second cavity 4. Electrical components such as the controller and frequency converter are integrated into the electrical control box 12. The compressor assembly 11 and the electrical control box 12 are arranged along the width of the air conditioning unit 1 within the second cavity 4. An air outlet 13 is provided on the bottom plate 1a of the casing of each evaporating cavity 6, and at least one return air outlet 14 is provided between two air outlets 13.

[0037] This structural layout allows for a more compact structure for the air conditioning unit 1. While meeting the cooling and heating performance requirements of the air conditioning unit 1, it also helps to reduce the height of the air conditioning unit 1, enabling an ultra-thin design. This further reduces the space occupied by the container 2 as a whole.

[0038] Two return air inlets 14 can be arranged between the two air supply outlets 13 according to the layout. In this embodiment, it is preferred that only one return air inlet 14 is arranged between the two air supply outlets 13. The return air inlet 14 is located directly below the condensing chamber 5. Above the return air inlet 14, there is a horizontal partition 15 and two inclined partitions 16, which separate the upper condensing chamber 5. The horizontal partition 15 and the two inclined partitions 16 are welded together or formed by bending a metal plate. The space below the horizontal partition 15 is connected to the evaporating chambers 6 on both sides, guiding the air entering from the return air inlet 14 into the evaporating chambers 6 on both sides, where it exchanges heat with the two evaporators 9 respectively, and then is sent to the container 2 through the air supply outlets 13 on both sides. The structure of the inclined partitions 16 helps to reduce the flow resistance when the air flows from the return air inlet 14 to the evaporating chamber 6.

[0039] In this embodiment, preferably, two rows of condensers 8 are arranged in the condensing cavity 5, and condensing fans 7 are installed between the two rows of condensers 8. Preferably, multiple condensing fans 7 are installed, arranged along the length of the air conditioning unit 1. Similarly, the two rows of condensers 8 are also arranged along the length of the air conditioning unit 1. To further reduce the height of the air conditioning unit 1 while ensuring the heat exchange efficiency of the condensers 8, the condensers 8 are preferably installed at an angle in the condensing cavity 5, and the angle of the inclined partition 16 is the same as the angle of the condensers 8. On the top plate of the casing corresponding to the condensing cavity 5 (not shown in the figure), a condensing air outlet 17 is provided corresponding to the condensing fan 7, and a condensing air inlet 18 is provided corresponding to the condenser 8.

[0040] like Figure 1 and Figure 4 As shown, in this embodiment, two first air vents 19 and one second air vent 20 are provided on the top plate 2a of the container 2, corresponding to two air supply vents 13 and one air return vent 14. An upwardly protruding waterproof platform 21 is provided around the first air vent 19 and the second air vent 20 respectively. The air supply vent 13 and the air return vent 14 are connected to the waterproof platform 21 at the corresponding first air vent 19 and the second air vent 20, and a sealing ring 22 is installed in the middle. The sealing ring 22 is preferably made of sealing sponge with a certain thickness.

[0041] In this way, by setting upward-protruding waterproof platforms 21 at the positions of the first air vent 19 and the second air vent 20, and connecting them to the bottom plate 1a of the air conditioning unit casing, the sealing position between the first air vent 19 and the second air vent 20 on the container 2 is raised above the surface of the top plate 2a. This height difference provides waterproofing. Simultaneously, a sealing ring 22 is also provided between the waterproof platform 21 and the bottom plate 1a, achieving a double waterproofing effect at the air vent connection. This avoids the problem in existing technologies where only a single sealing ring at the air vent connection is used for sealing; if the air conditioning unit 1 experiences horizontal shaking, the sealing ring 22 may deform, causing leakage. This waterproof structure significantly improves the sealing effect at the air vent connection between the top-mounted air conditioning unit 1 and the container 2, ensuring the safe and reliable operation of all components inside the container 2.

[0042] In this embodiment, it is further preferred that the cross-section of the waterproof platform 21 is an inverted L-shaped structure bent outwards. The bottom of the waterproof platform 21 is welded to the top plate 2a along the edges of the first air vent 19 and the second air vent 20 to ensure a sealing effect at the connection. The upper surface of the waterproof platform 21 is an installation plane 21a that mates with the bottom plate 1a of the air conditioning unit housing. A sealing ring 22 is installed between the installation plane 21a and the bottom plate 1a. During installation, after the air conditioning unit 1 is placed on the top plate 2a, the bottom plates 1a at the air supply vent 13 and the return air vent 14 are respectively placed on the installation plane 21a of the waterproof platform 21 at the first air vent 19 and the second air vent 20, and the sealing ring 22 is pressed to achieve a seal.

[0043] For the structure of the waterproof platform 21, another implementation manner is also provided in this embodiment. The cross-section of the waterproof platform 21 is a C-shaped structure, and the top and bottom edges of the waterproof platform 21 both extend outwards. The bottom edge is welded to the top plate 2a. This is beneficial to increasing the connection area between the waterproof platform 21 and the top plate 2a. The upper surface of the top edge of the waterproof platform 21 is also an installation plane 21a for docking with the bottom plate 1a of the housing.

[0044] For the sealing structure between the waterproof platform 21 and the bottom plate 1a, another implementation manner is also provided in this embodiment. A convex protrusion (not shown in the figure) protruding downwards is provided in a circle around the air supply port 13 and the air return port 14. The cross-section of the protrusion is preferably hemispherical. A concave groove (not shown in the figure) corresponding to the installation plane 21a of the waterproof platform 21 is provided in a circle. The cross-section of the groove is also preferably hemispherical and has a diameter larger than that of the protrusion. After installation, the protrusion in a circle and the sealing ring 22 at the corresponding position are pressed into the groove together, which can further improve the sealing effect at the connection.

[0045] In this embodiment, an upwardly protruding installation platform 23 is also provided on the top plate 2a of the container 2. The bottom plate 1a of the housing of the air conditioner unit 1 and the installation platform 23 are fixedly connected by a plurality of fasteners 24. The fasteners 24 are preferably bolts.

[0046] In this embodiment, it is further preferably that at least two installation platforms 23 extending along the length direction of the housing of the air conditioner unit 1 are provided on the top plate 2a. The length of the installation platform 23 is the same as the length of the bottom plate 1a. The first air outlet 19 and the second air outlet 20 are placed between the two installation platforms 23. The bottom of the installation platform 23 is welded to the top plate 2a, and the installation platform 23 can also play a certain waterproof role.

[0047] In this embodiment, it is even more preferably that the installation platform 23 is installed on the top plate 2a in a closed ring structure. The installation platform 23 plays the role of the first waterproof barrier, further improving the waterproof effect at the connection between the air conditioner unit 1 and the container 2, and ensuring the safe and reliable operation of each component in the container 2.

[0048] In this embodiment, it is also further preferably that the installation platform 23 is a mouth-shaped beam or a "channel" - shaped beam, and a maintenance opening 25 is provided at the position corresponding to the connection point of the fastener 24 on the outer side surface of the installation platform 23. This can not only ensure the waterproof effect of the installation platform 23, but also facilitate the disassembly and assembly of the fastener 24.

[0049] The present utility model also simultaneously provides an energy storage container, and the container air conditioner unit 1 as described above is installed above the top plate 2a of the energy storage container 2.

[0050] After adopting the above technical solutions, the following beneficial effects are achieved:

[0051] 1. By installing the air conditioning unit entirely on top of the container, the air conditioning unit itself does not need to occupy the space inside or on the outside of the energy storage container. This effectively solves the problem of the traditional air conditioning unit being installed inside the energy storage container or attached to the side of the container, which results in the air conditioning unit occupying a large space. This improves the utilization rate of the container's internal space and reduces the container's floor area.

[0052] 2. By installing upward-protruding waterproof platforms at the first and second air vents and connecting them to the bottom plate of the air conditioning unit casing, the sealing position between the first and second air vents on the container is raised above the surface of the top plate. The height difference is used for waterproofing. At the same time, a sealing ring is also installed between the waterproof platform and the bottom plate, achieving a double waterproof effect at the air vent connection. This significantly improves the sealing and waterproof performance of the top-mounted air conditioning unit and the container at the air vent connection, ensuring the safe and reliable operation of all components inside the container.

[0053] 3. The internal structure of the air conditioning unit is more rational and compact. While meeting the cooling and heating performance requirements of the air conditioning unit, it is conducive to reducing the height of the air conditioning unit and realizing the ultra-thin design of the air conditioning unit. This can further reduce the space occupied by the container as a whole.

[0054] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
