Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, and in particular to a shell structure and energy storage device. Background Technology

[0002] With the increasing global demand for renewable energy, energy storage systems are playing an increasingly important role in the entire energy system as a key component in balancing electricity supply and demand and improving energy efficiency. Among numerous energy storage solutions, liquid-cooled containers have attracted widespread attention due to their excellent thermal management performance. Liquid cooling technology achieves efficient heat exchange by directly or indirectly contacting the cooling liquid with the battery pack. This not only significantly increases the overall energy density of the container but also effectively ensures the uniformity of cell temperature distribution, which is of great significance for extending battery life and ensuring safe operation.

[0003] However, despite the significant benefits that liquid cooling technology has brought to the energy storage industry, some unresolved issues have also emerged during practical applications. The most prominent of these is the risk of coolant leakage, a significant concern due to the complexity of liquid cooling systems and the potential for aging after long-term operation. A leak could not only directly impact the safe and stable operation of energy storage devices but also potentially lead to serious consequences such as environmental pollution.

[0004] In related technologies, a common method for dealing with container leaks is to design one or two drain holes at the bottom of the container to drain the leaked liquid. However, this method has significant limitations. First, the number of drain holes is limited, and when the leakage is large, it cannot quickly and effectively drain all the liquid, causing accumulation. Second, this open discharge method reduces the overall sealing and waterproofing of the container, increasing the possibility of external moisture entering the interior, which in turn affects the working environment of electrical equipment. Finally, and most importantly, the lack of an effective coolant recovery mechanism means that leaked liquid is usually directly discharged into the external environment, which not only wastes valuable resources but may also pollute soil and water sources, violating the original intention of green development.

[0020] The housing structure of this application includes a base plate and a collection pipe. The base plate supports the energy storage module and has a drain port. The collection pipe connects to the drain port. The base plate has a first position and a second position. The first plane is parallel to a horizontal plane.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0044] In related technologies, a common method for dealing with container leaks is to design one or two drain holes at the bottom of the container to drain the leaked liquid. However, because the liquid spreads on the bottom surface of the container without a directional drainage design, not only is the drainage efficiency low, but it also easily leads to the accumulation of waste liquid, which can affect the equipment inside the container.

[0045] The following is for reference. Figure 1 to Figure 7 This describes the housing structure and energy storage device according to embodiments of the present invention.

[0046] Reference Figure 1 and Figure 2 In some embodiments, the housing structure of this application is used for an energy storage device, which includes a base plate 100 and a collection pipe 200. The base plate 100 is mounted on the base frame 400 of the housing and is used to support the energy storage module. The base plate 100 is provided with a drain port 110. The collection pipe 200 connects to the drain port 110. The base plate 100 has a first position 120 and a second position 130. The first plane is parallel to the horizontal plane. Compared with the first plane, the height of the first position 120 is higher than that of the second position 130, and the height of the base plate 100 decreases along the direction from the first position 120 to the second position 130. The drain port 110 is located at the second position 130. The side of the first position 120 facing the second position 130 is adapted to support the energy storage module so that the waste liquid of the energy storage module flows to the second position 130.

[0047] Specifically, in this embodiment, the base plate 100 is designed as an inclined surface to guide the waste liquid generated by the energy storage module smoothly into the drain port 110. When the energy storage module generates waste liquid, due to gravity, the waste liquid will naturally flow along the inclined direction of the base plate 100 to the lowest point, i.e., the location of the drain port 110, thereby effectively preventing the waste liquid from accumulating on the base plate 100 and reducing safety hazards. It should be noted that the purpose of the inclined surface design of the base plate 100 in this application is to allow the waste liquid to flow downward along the surface of the base plate 100 located inside the housing. Therefore, only the surface of the base plate 100 in contact with the waste liquid needs to be inclined; the shape and degree of inclination of other surfaces of the base plate 100 are not limited.

[0048] This structural design allows for the efficient and complete collection and discharge of waste liquid, thereby maintaining the cleanliness of the energy storage device's interior and improving its safety and reliability. Furthermore, this design helps extend the lifespan of the energy storage device by reducing the risk of damage caused by waste liquid corrosion.

[0049] It is understood that the base plate 100 is the bottom wall of the shell, and the drain port 110 can be a through hole starting on the base plate 100, or a specially designed valve for allowing liquid to pass through, which can connect the shell to the collection pipe 200. The purpose of this application is to tilt the base plate 100 so that the waste liquid in the shell flows down along the tilt direction of the base plate 100 under gravity. Therefore, the second position 130 is not limited to a certain point. It is a general term for positions that are lower in height than the first position 120 or the energy storage module. That is, the drain port 110 can be set at any position that meets the aforementioned height conditions, so that the liquid can flow down smoothly.

[0050] Of course, the first position 120 is not limited to a certain point value position. For example, it can be an edge of the base plate 100, which is higher than the edge called the second position 130 relative to the horizontal plane.

[0051] In some embodiments, the first position 120 can be a point value position. For example, the base plate 100 can also be a structure similar to a conical surface, with the top of the cone being the first position 120 and the bottom of the cone being the second position 130.

[0052] Similarly, based on the concept of this application, the base plate 100 can be assembled from multiple panels with different degrees of inclination, or it can be composed of a single inclined panel. Furthermore, considering that the inclined design of the base plate 100 may lead to slippage of the energy storage module, in some embodiments, friction structures to prevent slippage are provided on the floor, such as multiple parallel ribs perpendicular to the inclination direction. In this case, the height combination of the multiple ribs may not necessarily satisfy the condition that the surface height of the base plate 100 always decreases (for example, some ribs protrude higher, and some ribs protrude lower), but the surface of the base plate 100 always maintains a downward slope. These structures added for special purposes are sufficient as long as they do not obstruct the flow of waste liquid along the surface of the base plate 100 towards the drain port 110 at the second position 130 under the influence of gravity.

[0053] The collection pipe 200 can be a flexible or rigid pipe, and in some embodiments, it can also be configured as a tank. The purpose of designing the collection pipe 200 is to collect waste liquid and prevent it from flowing into the environment and causing pollution. For example, the collection pipe 200 can be connected to an external guide pipe 500, where the waste liquid collects and is then guided to a dedicated collection device through the guide pipe 500.

[0054] It is understood that in some embodiments, the tilt angle of the base plate 100 can be adjusted according to actual needs. For example, when the working environment of the energy storage device is relatively humid or the waste liquid has poor flowability, the tilt angle of the base plate 100 can be appropriately increased to accelerate the flow rate of the waste liquid and ensure that the waste liquid can be discharged quickly. In addition, the material of the base plate 100 also affects the flow performance of the waste liquid. Selecting materials with good corrosion resistance (such as stainless steel or Teflon-coated metal) can further improve the durability of the base plate 100 and reduce the residue of waste liquid on the surface of the base plate 100.

[0055] In addition, the design of the base plate 100 can also incorporate anti-slip textures, especially at the first position 120, to prevent the energy storage module from sliding during placement. These anti-slip textures can be formed through machining or chemical etching, without affecting the tilting characteristics of the base plate 100, while providing additional safety.

[0056] Reference Figure 1 to Figure 4 In some embodiments, the height of the base plate 100 gradually decreases along the direction from the first position 120 to the second position 130. This gradual change in height creates a continuous inclined surface on the base plate 100, which helps the waste liquid flow more evenly to the drain port 110 and avoids local water accumulation.

[0057] In this embodiment, the height change of the base plate 100 is linear and gradual, meaning the height difference from the first position 120 to the second position 130 is uniformly distributed. This design ensures that the waste liquid flows uniformly across the entire base plate 100, preventing waste liquid stagnation due to abrupt height changes. Simultaneously, this linear and gradual design simplifies the manufacturing process of the base plate 100 and reduces production costs. This gradual design significantly improves the flow efficiency of the waste liquid and reduces its residence time on the base plate 100, thereby further enhancing the safety and reliability of the energy storage device. Furthermore, this design also helps reduce the manufacturing difficulty of the base plate 100 and improves production efficiency.

[0058] It is understood that in some embodiments, the height variation of the base plate 100 can be non-linear. For example, the height of the base plate 100 can vary according to a certain curve (such as a parabola or exponential curve) to adapt to the flow characteristics of different types of waste liquids. This non-linear design can better guide the flow of waste liquids in certain specific situations. For example, when the waste liquid contains a large number of solid particles, the flow of waste liquid can be accelerated by increasing the inclination angle of the middle section, reducing the risk of blockage.

[0059] Furthermore, the surface of the base plate 100 can be designed with micro-grooves or raised textures to increase its surface roughness. This design enhances the friction between the waste liquid and the surface of the base plate 100, preventing splashing caused by the waste liquid sliding rapidly on the base plate 100, while also helping the waste liquid to disperse better and avoid localized accumulation. These grooves or raised features can be achieved through molding or subsequent processing, without affecting the overall tilting characteristics of the base plate 100, while providing additional functionality.

[0060] Reference Figure 2 ,as well as Figure 4 to Figure 7 In some embodiments, the second plane is parallel to the vertical plane, and the base plate 100 has two sides symmetrical about the second plane. The first position 120 is located between the two sides, and the distances from the two sides to the first position 120 are equal. Specifically, the base plate 100 has two inclined surfaces formed about the second plane. Both inclined surfaces can be used to mount energy storage modules, and the waste liquid generated by each energy storage module flows down the inclined surface on its respective side and into the drain port 110.

[0061] This symmetrical design makes the base plate 100 resemble a roof drainage structure, with both sides maintaining the same structure and function. This ensures that waste liquid flows evenly to the drain outlet 110 from both sides, improving work efficiency and space utilization. The symmetrical design also helps improve the structural stability of the base plate 100, reducing stress concentration problems caused by asymmetry.

[0062] It is understood that, in some embodiments, the symmetrical design of the base plate 100 may not be limited to geometric symmetry, but may also include symmetry in material distribution. For example, the same material may be used on both sides of the base plate 100 to ensure consistent physical and chemical properties on both sides. Furthermore, the thickness of the base plate 100 may also remain consistent on both sides to further improve structural stability.

[0063] Reference Figure 2 ,as well as Figure 4 to Figure 7 In some embodiments, the first plane is parallel to the horizontal plane, the second plane is parallel to the vertical plane, and the first direction is parallel to both the first and second planes. Along the first direction, the base plate 100 is provided with multiple drain ports 110. In this embodiment, the base plate 100 is provided with multiple drain ports 110 along the first direction. The design of multiple drain ports 110 also helps to improve the redundancy of the system. Even if one drain port 110 fails, the other drain ports 110 can still work normally, ensuring the effective discharge of waste liquid and avoiding the problem of waste liquid accumulation caused by blockage of a single drain port 110. The arrangement of multiple drain ports 110 also helps to improve the efficiency of waste liquid discharge and reduce the residence time of waste liquid on the base plate 100, thereby improving the safety and reliability of the energy storage device.

[0064] In some embodiments, multiple energy storage modules can be arranged on the base plate 100 along the first direction, and the purpose of setting multiple drain ports 110 is to correspond one-to-one with each energy storage module. Of course, according to the foregoing, one energy storage module can also correspond to multiple drain ports 110 to avoid waste liquid accumulation caused by blockage of a single drain port 110 when only a single drain port 110 is set.

[0065] It is understood that in some embodiments, the distribution of the multiple drain ports 110 can be uniform or non-uniform. For example, depending on the flow characteristics of the waste liquid and the inclination angle of the base plate 100, more drain ports 110 can be provided in areas where waste liquid tends to accumulate, while fewer drain ports 110 can be provided in areas where the waste liquid flows faster. This non-uniform distribution design can better adapt to different usage environments and improve the efficiency of waste liquid discharge.

[0066] Furthermore, the shape and size of the drain port 110 can be adjusted according to actual needs. For example, the drain port 110 can be designed as circular, square, or elliptical to accommodate different waste liquid flow rates and flow characteristics. The diameter of the drain port 110 can also be optimized according to the viscosity and flow rate of the waste liquid to ensure smooth discharge. These designs can be achieved through molding or machining, without affecting the overall structure of the base plate 100, while providing better waste liquid discharge performance.

[0067] Reference Figure 2 ,as well as Figure 4 to Figure 7In some embodiments, the housing structure includes two symmetrically arranged collection pipes 200 about a second plane. Multiple drain ports 110 located on one side of the second plane are connected to one of the collection pipes 200, and multiple drain ports 110 located on the other side of the second plane are connected to the other collection pipe 200. In this embodiment, the base plate 100 has multiple drain ports 110 along a first direction, and these drain ports 110 are respectively connected to two symmetrically arranged collection pipes 200 about the second plane. This design ensures that waste liquid flows evenly from different positions on the base plate 100 to the collection pipes 200, avoiding waste liquid accumulation caused by blockage of a single collection pipe 200. The symmetrical collection pipe design also helps improve the stability and reliability of the system and reduces stress concentration problems caused by asymmetry.

[0068] This symmetrical design not only ensures effective wastewater discharge but also improves the structural stability of the base plate 100 and the collection pipe 200, reducing the risk of deformation and damage caused by structural asymmetry. Furthermore, the symmetrical design helps simplify the manufacturing process and improve production efficiency.

[0069] It is understood that in some embodiments, multiple drain ports 110 may be connected to a single collection pipe 200; in some embodiments, a portion of the drain ports 110 may be connected to a single collection pipe 200, and another portion of the drain ports 110 may be connected to another collection pipe 200; in other embodiments, each drain port 110 may correspond to a separate pipe, and these pipes converge at a device for storing waste liquid to guide the waste liquid into a designated device.

[0070] It is understood that, in some embodiments, the cross-sectional shape of the two manifolds 200 can be circular, rectangular, or other shapes suitable for waste liquid flow. For example, a circular cross-section can reduce the resistance of the waste liquid in the pipe and improve flow efficiency; a rectangular cross-section can better adapt to space constraints and improve space utilization. The selection of these cross-sectional shapes can be optimized according to the actual application scenario and the characteristics of the waste liquid.

[0071] Additionally, the inner wall of the manifold 200 can be designed with a smooth surface to reduce waste liquid residue within the pipe. A smooth inner wall can be achieved through electroplating, spraying, or other surface treatment processes. This design further improves waste liquid flow efficiency and reduces the risk of blockage. Furthermore, the material of the manifold 200 can be selected from materials with good corrosion resistance (such as stainless steel or Teflon-coated metal) to improve pipe durability and extend service life.

[0072] Reference Figure 2 ,as well as Figure 4 to Figure 7In some embodiments, the collecting pipe 200 includes a collection port. The collecting pipe 200 has a first end and a second end. The first end is higher than the second end relative to a first plane, and the collection port is located at the second end. In this embodiment, the first end of the collecting pipe 200 is higher than the second end, and the collection port is located at the second end. This design utilizes gravity to allow the waste liquid to flow naturally from the first end to the second end and finally be discharged through the collection port. This inclined design ensures smooth discharge of waste liquid and reduces the accumulation of waste liquid in the pipe. In addition, this design also helps to reduce the accumulation of air bubbles in the pipe and improves the stability of waste liquid discharge.

[0073] It is understood that, in some embodiments, the inclination angle of the manifold 200 can be adjusted according to actual needs. For example, when the viscosity of the waste liquid is high or its fluidity is poor, the inclination angle of the manifold 200 can be appropriately increased to accelerate the flow rate of the waste liquid and ensure that the waste liquid can be discharged quickly. In addition, the length and diameter of the manifold 200 can also be optimized according to the actual application scenario to adapt to different waste liquid flow and pressure requirements.

[0074] In some embodiments, the design of the collection port can incorporate a filter screen or filter element to prevent solid particles in the waste liquid from entering the collection port, reducing the risk of clogging. The filter screen or filter element can be installed at the collection port via threaded connection, snap-fit ​​fixing, or other methods, facilitating regular cleaning and replacement. This design can further improve the reliability and safety of waste liquid discharge. Furthermore, the outlet of the collection port can be designed in a funnel or cone shape to increase the discharge speed and range of the waste liquid, reducing waste liquid accumulation at the outlet. These designs can be achieved through molding or machining, without affecting the overall structure of the collection pipe 200, while providing better waste liquid discharge performance.

[0075] Reference Figure 2 ,as well as Figure 4 to Figure 7 In some embodiments, the extension direction of the collection pipe 200 is parallel to the first direction, and the opposite ends of the container along the first direction are respectively configured as the first end and the second end. In this embodiment, the extension direction of the collection pipe 200 is parallel to the first direction, and the opposite ends of the container along the first direction are respectively configured as the first end and the second end of the collection pipe 200. This design ensures that the layout of the collection pipe 200 is consistent with the inclination direction of the bottom plate 100, improving the discharge efficiency of waste liquid, reducing the accumulation of waste liquid on the bottom plate 100, and facilitating the flow of waste liquid from the high point to the low point of the bottom plate 100, and finally discharging it through the collection port. In addition, this parallel design also helps to simplify the installation and maintenance of the collection pipe 200 and improve the overall reliability of the system.

[0076] It is understood that, in some embodiments, the length of the collection pipe 200 can be adjusted according to the size of the base plate 100 and the waste liquid flow rate. For example, for a larger base plate 100, a longer collection pipe 200 can be designed to ensure that the waste liquid can be fully collected and discharged. In addition, the diameter of the collection pipe 200 can also be optimized according to the viscosity and flow rate of the waste liquid to ensure that the waste liquid can flow smoothly and reduce the risk of blockage.

[0077] In addition, the material of the manifold 200 can be selected from materials with good corrosion resistance and pressure resistance, such as stainless steel or Teflon-coated metal. These materials can improve the durability and lifespan of the manifold 200 and reduce leakage problems caused by material aging. Furthermore, the inner wall of the manifold 200 can be designed with a smooth surface to reduce waste liquid residue in the pipe and further improve the flow efficiency of waste liquid.

[0078] Reference Figure 1 and Figure 4 In some embodiments, the two manifolds 200 are symmetrical about a second plane. This symmetrical design ensures that waste liquid flows evenly from both sides of the base plate 100 to the manifolds 200, avoiding waste liquid accumulation caused by blockage on one side of the pipe. The symmetrical manifold design also helps improve the stability and reliability of the system and reduces stress concentration problems caused by asymmetry. In addition, the symmetrical design helps simplify the manufacturing process and improve production efficiency.

[0079] It is understood that, in some embodiments, the cross-sectional shape of the two manifolds 200 can be circular, rectangular, or other shapes suitable for waste liquid flow. For example, a circular cross-section can reduce the resistance of the waste liquid in the pipe and improve flow efficiency; a rectangular cross-section can better adapt to space constraints and improve space utilization. The selection of these cross-sectional shapes can be optimized according to the actual application scenario and the characteristics of the waste liquid.

[0080] Understandably, the connection method of the manifold 200 can be threaded, welded, or other reliable methods to ensure the sealing and stability of the pipeline. For example, a sealing ring or sealant can be used at the connection between the manifold 200 and the base plate 100 to prevent waste liquid leakage. The selection of these connection methods can be optimized according to the actual application scenario and the size of the pipeline to ensure the reliability and safety of the system.

[0081] Reference Figure 5 to Figure 7In some embodiments, the housing structure includes a floor drain 300, which is installed at the drain port 110. In this embodiment, the floor drain 300 is installed at the drain port 110 of the base plate 100. On the one hand, the design of the floor drain 300 can further improve the discharge efficiency of waste liquid, ensuring that waste liquid can flow smoothly from the base plate 100 into the collection pipe 200. On the other hand, the floor drain 300 typically includes a filter screen, which can prevent large particulate impurities from entering the collection pipe 200, reduce the risk of blockage, and improve the reliability of waste liquid discharge. In addition, the design of the floor drain 300 can also increase the sealing between the base plate 100 and the collection pipe 200, prevent waste liquid leakage, and improve the safety and stability of the system.

[0082] Understandably, in some embodiments, the filter screen of the drain 300 may be designed to be removable for easy regular cleaning and replacement. The pore size of the filter screen can be optimized according to the particle size of impurities in the waste liquid to ensure optimal filtration. Furthermore, the drain 300 can be made of materials with good corrosion resistance, such as stainless steel or Teflon-coated metal, to improve its durability and lifespan.

[0083] In addition, the floor drain 300 can be installed using threaded connections, snap-fit ​​fastening, or other reliable connection methods to ensure the sealing and stability between the floor drain 300 and the base plate 100. For example, a sealing ring or sealant can be used at the connection between the floor drain 300 and the base plate 100 to prevent waste liquid leakage. The selection of these connection methods can be optimized according to the actual application scenario and the size of the floor drain 300 to ensure the reliability and safety of the system.

[0084] Reference Figure 1 to Figure 7 The second aspect of this utility model provides an energy storage device, including the housing structure of any of the foregoing embodiments. The energy storage device also includes a battery mounted on a base plate 100. The design of the housing structure ensures that waste liquid generated during battery use can be smoothly discharged, reducing the accumulation of waste liquid on the base plate 100 and improving the safety and reliability of the energy storage device. The inclined design of the base plate 100, the arrangement of multiple drain ports 110, and the cooperation of the collection pipe 200 and the floor drain 300 together constitute an efficient waste liquid discharge system.

[0085] This design effectively manages the waste liquid generated during battery use, reducing its impact on the internal environment of the energy storage device and improving its safety and reliability. Furthermore, this design helps extend the lifespan of the energy storage device and reduces the risk of damage caused by waste liquid corrosion.

[0086] It is understood that, in some embodiments, the type and number of batteries can be selected and configured according to the actual needs of the energy storage device. For example, lithium-ion batteries, lead-acid batteries, or other types of batteries can be used to meet different energy density and power requirements. Furthermore, the batteries can be installed using fixed brackets, flexible clamps, or other reliable fixing methods to ensure the stability and safety of the batteries on the base plate 100.

[0087] In some embodiments, the housing structure of the energy storage device can be designed to be modular to facilitate maintenance and upgrades. For example, the housing structure can be divided into multiple removable parts, each of which can be replaced or repaired individually without affecting the normal operation of other parts. This modular design can improve the maintainability and flexibility of the energy storage device, and reduce maintenance costs and downtime.

[0088] In some embodiments, the control system of the energy storage device can be integrated into the housing structure to achieve intelligent management and monitoring of the battery. For example, the control system can monitor parameters such as battery temperature, voltage, and current, promptly detect abnormalities, and take corresponding measures to ensure the normal operation of the energy storage device. The control system can also be connected to external communication equipment to achieve remote monitoring and management, improving the intelligence level of the energy storage device.
