Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a battery compartment cooling system and a ship. Background Technology

[0002] With the rapid development of ship electrification technology, high-power battery packs are being used more and more widely in ship battery compartments. During the operation of the battery pack, a large amount of heat will be generated continuously. If the heat cannot be dissipated in time, it will not only lead to battery capacity decay and shorten service life, but may also cause safety risks such as thermal runaway. Therefore, an efficient and stable heat dissipation system has become one of the core keys to battery compartment design.

[0003] Existing battery compartment heat dissipation technologies have many shortcomings. Traditional heat dissipation methods mostly use air cooling, but its cooling efficiency is low and its heat dissipation effect is greatly affected by the ambient temperature, making it difficult to meet the rapid heat dissipation requirements of high-power battery compartments. At the same time, during the air cooling process, it is easy to bring external dust and impurities into the battery compartment, which affects the cleanliness of the battery compartment and accelerates the aging and wear of the battery and related electrical components.

[0004] To improve heat dissipation, some existing technologies employ water cooling solutions. However, these solutions often only cool individual battery cells or localized areas, failing to provide systematic temperature control for the entire battery pack. This results in uneven temperature distribution within the pack, with the risk of localized overheating remaining, and the overall uniformity and reliability of heat dissipation for the battery pack cannot be guaranteed. Furthermore, the piping in existing water cooling systems is often located outside the battery pack or in confined spaces, leading to complex and messy layouts. This not only occupies additional installation space and reduces the space utilization of the battery pack but also results in poor compatibility with different battery pack sizes. The installation process is cumbersome, and subsequent maintenance and repair are difficult, hindering practical engineering applications and widespread adoption. Some water cooling systems even directly channel cooling water into the battery pack, resulting in complex structures and a higher risk of damaging the battery pack.

[0005] In summary, existing battery compartment cooling technologies still have significant shortcomings in terms of heat dissipation efficiency, temperature uniformity, structural adaptability, and ease of maintenance. There is an urgent need for a battery compartment cooling system that can solve these problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, the present invention discloses a battery compartment cooling system.

[0007] In a first aspect, this utility model provides a battery compartment cooling system, comprising:

[0008] The battery holder body includes:

[0009] Multiple first hollow plates are arranged horizontally and spaced apart vertically.

[0010] Multiple second hollow panels are arranged vertically and spaced apart horizontally; each second hollow panel is fixedly connected to and fluidly connected with multiple first hollow panels, and the multiple first hollow panels and multiple second hollow panels intersect to form multiple accommodating spaces in a matrix arrangement;

[0011] The seawater inlet is connected to the interior of the first hollow plate and the second hollow plate, and is used to allow seawater to flow into the interior of the first hollow plate and the interior of the second hollow plate.

[0012] The seawater outlet is connected to the interior of the first hollow plate and the second hollow plate, and is used to allow seawater to flow out of the interior of the first hollow plate and the second hollow plate.

[0013] A battery pack is disposed within a receiving space and abuts against at least one wall located within the receiving space.

[0014] By adopting the above technical solution, in the battery compartment cooling system of this utility model, multiple first hollow plates and multiple second hollow plates are fixedly connected and fluidly communicated to form the battery rack body. This not only realizes the regular and high-density arrangement of the battery pack to make efficient use of the internal space of the battery compartment, but also enables the battery rack body to have the dual functions of structural support and cooling channel. Low-temperature seawater can flow smoothly inside all hollow plates, achieving global and efficient cooling of the battery pack and battery compartment space. This helps to ensure uniform temperature distribution in various areas inside the battery pack and battery compartment. The above structure does not require additional independent cooling pipes and battery pack support frames, which helps to simplify the structure of the entire battery compartment cooling system. It can be adapted to various specifications of battery compartments, reducing costs. Moreover, seawater is widely available and inexpensive as a cooling medium.

[0020] An auxiliary cooling water pipe is located between the top of the battery pack and the lower surface of the first hollow plate located at the top in the housing space, and is positioned relatively closer to the top of the battery pack. Seawater flows inside the auxiliary cooling water pipe.

[0021] The secondary water inlet is connected to the auxiliary cooling water pipe and is used to supply seawater into the auxiliary cooling water pipe;

[0022] The secondary outlet is connected to the auxiliary cooling water pipe and is used to supply seawater to flow out of the auxiliary cooling water pipe;

[0023] The auxiliary water pump, connected to the auxiliary water inlet, is used to pump seawater into the auxiliary water inlet.

[0027] The second one-way control valve is located between the auxiliary water pump and the auxiliary water inlet, and is used to control the flow rate of seawater entering the auxiliary water inlet.

[0028] According to another specific embodiment of the present invention, the first hollow plate and the second hollow plate are square tubes, and at least one of the first hollow plate, the second hollow plate and the auxiliary cooling water pipe is composed of multiple water pipe sections.

[0029] Among them, adjacent water pipe sections are connected by flanges; or,

[0030] Two adjacent water pipe sections are respectively an external thread water pipe section and an internal thread water pipe section. The end of the internal thread water pipe section has an internal thread, and the end of the external thread water pipe section has an external thread that mates with the internal thread. The external thread water pipe section is screwed into the internal thread water pipe section to fix the two adjacent water pipe sections together.

[0031] According to another specific embodiment of the present invention, it further includes:

[0032] A space temperature sensor, located on the battery rack body, is used to detect the temperature inside the battery compartment.

[0033] A battery pack temperature sensor is located in the battery pack and is used to detect the temperature of the battery pack.

[0034] Secondly, the present invention discloses a battery compartment cooling control method, which controls the battery compartment cooling system in any of the embodiments of the first aspect to cool the battery compartment. The initial flow state of seawater in the first hollow plate is a preset initial state, which is that the seawater does not flow or the seawater flows at a preset minimum heat dissipation flow rate. The battery compartment cooling control method includes:

This allows for stratified cooling control of each layer of battery packs: maintaining the seawater at its original state when the temperature meets the standard, and adjusting the seawater flow rate in the corresponding first hollow panel in a timely manner when the temperature is too high, without directly increasing the seawater flow rate in all first hollow panels. This helps to reduce energy consumption while ensuring cooling efficiency, effectively avoiding the impact of localized high temperatures on the battery pack's lifespan, and reducing safety risks. The above control method not only ensures the uniformity and reliability of cooling for each layer of battery packs but also dynamically adjusts the flow rate according to actual temperature requirements, significantly improving the energy efficiency and adaptability of the cooling system, and further enhancing the intelligence and practicality of the battery compartment cooling system.

[0038] According to another specific embodiment of this utility model, adjusting the flow state and flow rate of seawater within the first hollow plate corresponding to each layer of the containment space specifically includes:

[0048] To control the flow of seawater within the auxiliary cooling water pipes, the required seawater flow rate for the auxiliary cooling water pipes is determined using the following formulas 3 and 4:

[0049] (Formula 3);

[0050] (Formula 4);

[0051] in, To assist the cooling water pipes with the required seawater flow rate, To accommodate the highest battery pack temperature within the space corresponding to the auxiliary cooling water pipes, This is the normal battery pack temperature threshold. The second cooling coefficient, It is 700-830. The density of seawater, The specific heat capacity of seawater;

[0052] Adjust the seawater flow rate in the auxiliary cooling water pipe based on the seawater flow rate until the highest battery pack temperature does not exceed the normal battery pack temperature threshold.

[0053] Thirdly, embodiments of this utility model disclose a battery compartment cooling control device, which controls the battery compartment cooling system in any of the aforementioned first aspects to cool the battery compartment. The initial flow state of seawater within the first hollow plate is a preset initial state, wherein the preset initial state is that the seawater does not flow or the seawater flows at a preset minimum heat dissipation flow rate. The battery compartment cooling control device includes:

[0054] The temperature detection module is used to obtain the lowest space temperature of each layer of the containment space corresponding to each first hollow plate in the battery compartment cooling system.

[0055] The flow control module is used to determine whether the minimum space temperature corresponding to each layer of the containment space is not higher than the normal space temperature threshold. If so, the seawater in the first hollow plate corresponding to each layer of the containment space is kept in a preset initial state. If not, the flow state and flow rate of the seawater in the first hollow plate corresponding to each layer of the containment space are adjusted until the minimum space temperature is not higher than the normal space temperature threshold.

[0056] By adopting the above technical solution, for the battery compartment cooling system in any embodiment of the first aspect, the battery compartment cooling control device can accurately monitor the temperature status of each layer of battery packs by precisely acquiring the lowest space temperature of each layer corresponding to each first hollow plate. This allows for layered cooling control of each battery pack layer: maintaining the seawater at its original state when the temperature is within acceptable limits, and adjusting the seawater flow rate in the corresponding first hollow plate when the temperature is too high, without directly increasing the seawater flow rate in all first hollow plates. This helps to reduce energy consumption while ensuring cooling efficiency, effectively avoiding the impact of localized high temperatures on the battery pack's lifespan, and reducing safety risks. The above control method ensures the uniformity and reliability of cooling for each layer of battery packs, and dynamically adjusts the flow rate according to actual temperature requirements, significantly improving the energy efficiency and adaptability of the cooling system, further enhancing the intelligence and practicality of the battery compartment cooling system.

This helps to reduce energy consumption while ensuring cooling efficiency, effectively avoiding the impact of localized high temperatures on the battery pack's lifespan, and reducing safety risks. The above control method ensures the uniformity and reliability of cooling for each layer of battery packs, and dynamically adjusts the flow rate according to actual temperature requirements, significantly improving the energy efficiency and adaptability of the cooling system, further enhancing the intelligence and practicality of the battery compartment cooling system.

To provide a deep understanding of this utility model, many specific details will be included in the following description. This utility model may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of this utility model, some specific details will be omitted in the description. It should be noted that, without conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0074] It should be noted that in this specification, similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0075] The terms “first”, “second”, etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0076] In the description of this embodiment, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0077] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0078] Firstly, reference Figure 1 and combined Figure 2 This utility model provides a battery compartment cooling system, including a battery rack body and a battery pack.

[0079] The battery holder body 0 includes multiple first hollow plates 1 and multiple second hollow plates 2, the multiple first hollow plates 1 being arranged in a horizontal direction (e.g., Figure 1 Set the Y direction in the middle and along the vertical direction (e.g., the Y direction in the middle) ... Figure 1 The first hollow plates 1 are arranged vertically and horizontally at intervals (in the X direction). Each second hollow plate 2 is fixedly connected to and fluidly communicated with multiple first hollow plates 1. The multiple first hollow plates 1 and multiple second hollow plates 2 intersect to form multiple accommodating spaces in a matrix arrangement.

[0080] The battery holder body 0 also includes a seawater inlet (not shown in the figure) and a seawater outlet (not shown in the figure). The seawater inlet communicates with the interior of the first hollow plate 1 and the second hollow plate 2, and is used to allow seawater to flow into the interior of the first hollow plate 1 and the second hollow plate 2. The seawater outlet communicates with the interior of the first hollow plate 1 and the second hollow plate 2, and is used to allow seawater to flow out from the interior of the first hollow plate 1 and the second hollow plate 2. The battery pack 3 is disposed within the receiving space and abuts against at least one wall located within the receiving space.

[0081] Through the above technical solution, in the battery compartment cooling system of this utility model, multiple first hollow plates 1 and multiple second hollow plates 2 are fixedly connected and fluidly communicated to form a battery rack body 0. The battery rack body 0 has multiple accommodating spaces arranged in a matrix, realizing the regular and high-density arrangement of the battery pack 3, and can efficiently utilize the internal space of the battery compartment 00. At the same time, by using first hollow plates 1 and second hollow plates 2 to form the battery rack body 0, the battery rack body 0 can have the dual functions of structural support and cooling channels, and low-temperature seawater can circulate inside the multiple first hollow plates 1 and multiple second hollow plates 2. This design breaks through the traditional external or partial piping layout of existing technologies, and realizes an integrated internal piping layout. In the above embodiment, by directly integrating the cooling water pipes inside the battery compartment 00, or more specifically, inside the battery rack body 0, the low-temperature seawater flowing inside the battery rack body 0 can be used to directly cool the internal space of the battery compartment 00. It can also cool the battery pack 3 placed on the battery rack body 0, which greatly improves the cooling efficiency of the battery compartment 00 and the battery pack 3, and achieves a rapid and efficient reduction in the overall temperature of the battery compartment 00. It can meet the heat dissipation needs of multiple battery packs, especially the heat dissipation needs of high-power battery packs, and improve the safety of use.

[0082] Furthermore, seawater is a widely available and inexpensive cooling medium. The aforementioned battery compartment cooling system can be used on ships, where seawater can continuously flow within the first hollow plate 1 and the second hollow plate 2 while the ship is sailing at sea. Compared to the traditional methods of "air cooling by battery compartment fans" and "water cooling by connecting each battery pack to cooling pipes separately," the above embodiment of this utility model, based on the special characteristics and advantages of the ship battery compartment usage scenario, utilizes recyclable low-temperature seawater for cooling. Through the reasonable arrangement of cooling water pipes, the entire battery compartment 00 is cooled, and it is physically separated from the battery packs 3, ensuring that all battery packs are in a suitable and usable ambient temperature. This helps to ensure uniform temperature distribution in all areas of the battery packs 3 and the battery compartment 00.

[0083] Because ships typically have limited space, it is inconvenient to arrange complex piping structures, and personnel maintenance is also inconvenient. In the above embodiments of this utility model, by making the battery rack body itself a hollow structure with seawater flowing inside, there is no need to set up additional independent cooling pipes and battery pack support frames. This helps to simplify the structure of the entire battery compartment cooling system, can adapt to various battery compartment specifications, reduce costs, and is particularly suitable for ship battery compartments, which can significantly improve the practicality and economy of the system.

[0084] Furthermore, in the above embodiment, the battery compartment cooling system also includes a main water inlet pipe 41 and a main water outlet pipe 42. One end of the main water inlet pipe 41 is connected to seawater, and the other end is connected to a seawater inlet. One end of the main water outlet pipe 42 is connected to seawater, and the other end is connected to a seawater outlet. Seawater flows into the interior of the first hollow plate 1 and the second hollow plate 2 through the main water inlet pipe 41, and flows out of the interior of the first hollow plate 1 and the second hollow plate 2 through the main water outlet pipe 42. The main water outlet pipe 42 can discharge seawater overboard. Seawater from multiple first hollow plates 1 and multiple second hollow plates 2 can all converge into the main water outlet pipe 42 and be discharged together through the main water outlet pipe 42, simplifying the pipeline structure. Furthermore, at least a portion of the main water inlet pipe 41 can be located inside the ship's cabin outside the battery compartment 00, and at least a portion of the main water inlet pipe 41 can extend into the interior of the battery compartment 00. The main water inlet pipe 41 can be located at the bottom of the ship's cabin or the bulkhead of the battery compartment 00.

[0085] Furthermore, in the above embodiments, the battery pack 3 is fixedly connected to the battery rack body 0, so that the turbulence that occurs when the ship is sailing will not cause the battery pack 3 to slip off the battery rack body 0, which helps to ensure the reliability of the entire battery compartment 00 and the cooling system.

[0086] Furthermore, in the above embodiments, the battery pack 3 abuts against three walls of the receiving space, namely the bottom surface and two side surfaces. This arrangement not only helps to securely hold the battery pack 3 within the receiving space but also increases the contact area between the battery holder body 0 and the battery pack 3. This increases the contact area between the seawater and the battery pack 3, allowing more seawater to carry away the heat generated by the battery pack 3 during operation, further improving cooling efficiency, ensuring the normal operation of the battery pack 3, and enhancing safety.

[0087] Furthermore, in the above embodiments, reference continues to be made to... Figure 1 and combined Figure 2 The system includes multiple seawater inlets, each connected to a different first hollow plate 1. The battery compartment cooling system also includes a main water pump 4 and a first one-way control valve 5. The main water pump 4 is connected to the multiple seawater inlets and is used to pump seawater into them. The first one-way control valve 5 is located between the main water pump 4 and the multiple seawater inlets and is used to control the flow rate of seawater entering the seawater inlets.

[0088] This configuration, by combining multiple seawater inlets connected to different first hollow plates 1, along with the main water pump 4 and the first one-way control valve 5, further optimizes the heat dissipation performance and controllability of the battery compartment cooling system. The main water pump 4 provides a stable and adjustable power source for seawater circulation, meeting the high-flow heat dissipation requirements of the high-power battery pack under full load operation, and adapting to the cooling load under different operating conditions by adjusting the pump power. The first one-way control valve 5 controls the flow rate of seawater entering the first hollow plate 1 and effectively prevents seawater backflow, avoiding damage to the pump and pipeline caused by system pressure fluctuations.

[0089] Furthermore, in the above embodiments, reference continues to be made to... Figure 1 and combined Figure 2 There are multiple first one-way control valves 5, which are respectively located between the main water pump 4 and different seawater inlets to control the flow rate of seawater flowing into different first hollow plates 1.

[0090] This configuration allows for precise distribution of seawater to each layer of the first hollow panel 1 via multiple seawater inlets and their corresponding first one-way control valves 5. This helps control the seawater flow into each first hollow panel 1 based on the temperature of different battery packs 3, thus providing more targeted cooling for different battery packs 3 and significantly improving the uniformity of heat dissipation in multi-layer battery packs. The first one-way control valve 5 not only precisely controls the seawater flow for individual channels or the entire system, enabling targeted cooling of locally overheated areas, but also provides a convenient means of interrupting flow for later maintenance (such as individual inspection of a specific first hollow panel 1). The synergistic effect of these structures allows the cooling system to maintain a compact integrated framework while further improving heat dissipation efficiency, temperature control accuracy, and operational reliability, making it particularly suitable for the complex heat dissipation needs of large or multi-layer battery compartments.

[0091] Furthermore, in the above embodiments, reference continues to be made to... Figure 1 and combined Figure 2 The battery compartment cooling system also includes an auxiliary cooling water pipe 6, a secondary water inlet (not shown in the figure), a secondary water outlet (not shown in the figure), and a secondary water pump 7. The auxiliary cooling water pipe 6 is located between the top of the battery pack 3 and the lower surface of the first hollow plate 1 located at the top of the housing space, and is positioned relatively closer to the top of the battery pack 3. Seawater flows through the auxiliary cooling water pipe 6. The secondary water inlet is connected to the auxiliary cooling water pipe 6 to allow seawater to enter the auxiliary cooling water pipe 6. The secondary water outlet is connected to the auxiliary cooling water pipe 6 to allow seawater to flow out of the auxiliary cooling water pipe 6. The secondary water pump 7 is connected to the secondary water inlet to pump seawater into the secondary water inlet. With this configuration, the auxiliary cooling water pipe 6 can simultaneously cool the adjacent battery pack 3 and the interior space of the compartment, further improving cooling efficiency. Furthermore, there are multiple auxiliary cooling water pipes 6, with a corresponding auxiliary cooling water pipe 6 above each layer of battery pack 3, thereby enabling cooling of the entire interior space of the battery compartment 00 and multiple battery packs 3.

[0092] More specifically, in the above embodiments, the battery compartment cooling system further includes an auxiliary water inlet pipe 61 and an auxiliary water outlet pipe 62. One end of the auxiliary water inlet pipe 61 is connected to seawater, and the other end is connected to an auxiliary water inlet. One end of the auxiliary water outlet pipe 62 is connected to seawater, and the other end is connected to an auxiliary water outlet. Seawater flows into the auxiliary cooling water pipe 6 through the auxiliary water inlet pipe 61 and flows out of the auxiliary cooling water pipe 6 through the auxiliary water outlet pipe 62, which can discharge seawater overboard. Furthermore, at least a portion of the auxiliary water inlet pipe 61 can be located inside the ship's cabin outside the battery compartment 00, and at least a portion of the auxiliary water inlet pipe 61 can extend into the interior of the battery compartment 00. The auxiliary water inlet pipe 61 can be located at the bottom of the ship's cabin or the bulkhead of the battery compartment 00.

[0093] In the above embodiments, by rationally arranging the main water inlet pipe 41, the main water outlet pipe 42, the auxiliary water inlet pipe 61, and the auxiliary water outlet pipe 62, the pipes can be arranged to fit against the cabin wall or along the gaps in the battery pack, thereby achieving full coverage of the cabin space and global cooling of the cabin space, which helps to improve cooling efficiency.

[0094] Furthermore, by setting up the aforementioned main inlet pipe 41, main outlet pipe 42, auxiliary inlet pipe 61, and auxiliary outlet pipe 62, along with multiple seawater inlets and multiple auxiliary cooling water pipes 6, a multi-stage pipeline design of "main inlet pipe - branch pipes - main return pipe" can be formed. Combined with high-flow circulation pumps (i.e., main pump 4 and auxiliary pump 7) and high-efficiency heat exchangers, the cooling water flow efficiency and heat exchange rate can be improved, enhancing the overall cooling effect and forming a highly efficient circulating heat dissipation system. Multiple pipelines can be evenly distributed to cover the interior space of the battery compartment 00, effectively solving the problem of uneven temperature distribution within the compartment and reducing the risk of localized high temperatures.

[0095] Furthermore, by using the main water pump 4 and the auxiliary water pump 7 to control the seawater flowing inside the battery rack body 0 and the seawater flowing inside the auxiliary cooling water pipe 6 respectively, the seawater flow rate of both can be controlled more specifically, thereby achieving more efficient cooling and helping to improve the uniformity of the overall temperature distribution inside the battery compartment 00.

[0096] Furthermore, in the above embodiments, reference is made to... Figure 2 and combined Figure 3 The auxiliary cooling water pipes 6 are serpentine pipes at the top of each battery pack 3. This arrangement, with the auxiliary cooling water pipes 6 intersecting the reserved gap between the battery pack 3 and the battery frame body 0, increases the flow of seawater above the battery pack 3 and increases the contact area between the seawater and the battery pack. Combined with the first hollow plate 1 at the bottom of the battery pack 3 and the second hollow plates 2 on both sides, it can cool the battery pack 3 from multiple directions (top, bottom, left, and right) and also cool the space inside the battery compartment 00, ensuring sufficient heat dissipation. The seawater only circulates in the pipes outside the battery pack 3, which also helps to avoid interfering with the normal operation of the battery pack 3.

[0097] Furthermore, in the above embodiments, reference continues to be made to... Figure 1 and combined Figure 2 The battery compartment cooling system also includes a second one-way control valve 71. The second one-way control valve 71 is located between the auxiliary water pump 7 and the auxiliary water inlet, and is used to control the flow rate of seawater entering the auxiliary water inlet. Furthermore, there are multiple second one-way control valves 71, which can individually control the flow rate of seawater entering different auxiliary cooling water pipes 6, thereby more specifically cooling the battery packs 3 in different layers and helping to improve the uniformity of temperature distribution.

[0098] Furthermore, in the above embodiments, reference is made to... Figure 4 At least one of the first hollow plate 1, the second hollow plate 2, and the auxiliary cooling water pipe 6 has multiple heat dissipation fins 8 on its outer wall. Furthermore, at least one of the main inlet pipe 41, the main outlet pipe 42, the auxiliary inlet pipe 61, and the auxiliary outlet pipe 62 also has multiple heat dissipation fins 8 on its outer wall. The main inlet pipe 41, the main outlet pipe 42, the auxiliary inlet pipe 61, and the auxiliary outlet pipe 62 can all be pipes with a circular cross-section. This arrangement helps to enhance the heat dissipation and cooling effect.

[0099] Furthermore, in the above embodiments, the entire battery holder body 0 is sealed and composed of hollow, interconnected square or round tubes, wherein the outer wall of the round tube may also be provided with the aforementioned heat dissipation fins 8. In this embodiment, the first hollow plate 1 and the second hollow plate 2 are square tubes.

[0100] Furthermore, at least one of the first hollow plate 1, the second hollow plate 2, and the auxiliary cooling water pipe 6 is composed of multiple water pipe segments.

[0101] The adjacent water pipe sections are connected by flanges and sealed. This configuration allows for the adjustment of the pipe dimensions of the battery compartment cooling system according to the space available in the battery compartment and cabin of the actual vessel, making it suitable for cabins of different sizes, such as those with small compartments, thereby improving space utilization.

[0102] In another embodiment, reference Figure 5 The two adjacent water pipe sections are respectively an externally threaded water pipe section 9 and an internally threaded water pipe section 10. The end of the internally threaded water pipe section 10 has an internal thread 101, and the end of the externally threaded water pipe section 9 has an external thread 91 that mates with the internal thread 101. The externally threaded water pipe section 9 is screwed into the internally threaded water pipe section 10 to fix the two adjacent water pipe sections together. This configuration provides a modular design for the battery compartment cooling system piping. The piping adopts an adjustable-length segmented structure, allowing for flexible layout adjustments according to battery compartments of different sizes and specifications. Furthermore, the above-mentioned piping facilitates installation and maintenance; damaged parts can be replaced individually, thereby improving maintenance efficiency and reducing operating costs. Furthermore, the piping and the battery compartment body can use quick-connect interfaces to simplify the installation and maintenance process.

[0103] Furthermore, in the above embodiments, reference is made to... Figure 3The battery compartment cooling system also includes a space temperature sensor 11 and a battery pack temperature sensor 12. The space temperature sensor 11 is located on the battery rack body 0 and is used to detect the temperature of the space inside the battery compartment 00. The battery pack temperature sensor 12 is located on the battery pack 3 and is used to detect the temperature of the battery pack 3. Furthermore, there are multiple space temperature sensors 11 and multiple battery pack temperature sensors 12. This arrangement allows for the detection of the temperature of the battery pack 3 and the temperature of the space inside the battery compartment 00 through multiple sensors, thereby enabling the control of the seawater flow into different auxiliary cooling water pipes 6 and each layer of the first hollow plate 1 based on the detected temperature, thus helping to improve cooling efficiency.

[0104] In the battery compartment cooling system of the above embodiments of this utility model, the cooling efficiency can be significantly improved through the configuration methods described in these embodiments: compared with traditional air cooling, the cooling rate is increased by more than 30%; compared with local water cooling, the temperature uniformity inside the compartment is improved by 40%, and the temperature inside the compartment can be quickly controlled within a safe range, ensuring battery performance and lifespan. Furthermore, by setting multiple sensors for comprehensive temperature control and adjusting the seawater flow in different pipelines, local high temperatures can be eliminated, reducing the risk of battery thermal runaway; integrating multiple pipelines inside the compartment reduces the impact of the external environment on the cooling system, improves system operational stability, and enhances the safety and reliability of the battery compartment cooling system. The above-mentioned battery compartment cooling system is also easy to install and maintain. Modular piping and quick-connect design can shorten installation time by 50%; by setting the pipelines in a segmented structure, local maintenance is convenient, reducing later maintenance costs. Furthermore, the above-mentioned battery compartment cooling system can flexibly adapt to battery compartments of different sizes and types without large-scale modification of the compartment structure, and its applicable scenarios cover multiple fields such as marine energy storage, new energy vehicles, and energy storage power stations, demonstrating wide adaptability.

[0105] Secondly, refer to Figure 6 This utility model discloses a battery compartment cooling control method, which controls the battery compartment cooling system in any of the aforementioned first aspects to cool the battery compartment. The initial flow state of seawater within the first hollow plate is a preset initial state, which is either no seawater flow or seawater flow at a preset minimum heat dissipation flow rate. The battery compartment cooling control method includes:

[0106] S1: Obtain the lowest space temperature of each layer of the containment space corresponding to each first hollow plate in the battery compartment cooling system.

[0107] S2: Determine whether the minimum space temperature corresponding to each layer of the containment space is not higher than the normal space temperature threshold; if yes, then execute S21: maintain the seawater in the first hollow plate corresponding to each layer of the containment space in the preset initial state; if no, then execute S22: adjust the flow state and flow rate of seawater in the first hollow plate corresponding to each layer of the containment space until the minimum space temperature is not higher than the normal space temperature threshold.

[0108] Specifically, multiple space temperature sensors can be installed at the location of each layer of the battery compartment cooling system, as detailed below. Figure 1 For example, the k-th layer accommodating space (the corresponding first hollow panel is denoted as the k-th layer first hollow panel) can be equipped with m space temperature sensors, and the temperature of each space temperature sensor in the k-th layer is denoted as T. i Where i = 1, 2, ..., m, then the spatial temperature T of the k-th layer is calculated. air-count,k =max(T1,T2,T3,...T i ,...T m ), Space calculation temperature T air-count,k This refers to the highest possible temperature within each floor's space. The normal space temperature threshold can be set as a constant T. air-set This threshold can be determined based on the performance and parameters of the battery pack, for example, it can be within the range of 20-30℃. In this embodiment, the normal space temperature threshold can be set to 26℃.

[0109] The preset minimum heat dissipation flow rate refers to the minimum seawater flow rate that can meet the basic cooling requirements of the battery pack, or it can be understood as the seawater flow rate corresponding to the water pump operating at its minimum power. The preset minimum heat dissipation flow rate can be determined according to actual needs. In step S22, the flow rate can be controlled by the water pump (e.g., the main water pump 4) and the control valve (e.g., the first one-way control valve 5).

[0110] Continue to combine Figures 1-3 For example, when the temperature of any one of the space temperature sensors 11 is greater than the normal space temperature threshold T air-set At that time, the central processing unit will calculate the spatial calculated temperature T of the k-th layer containing space corresponding to this spatial temperature sensor 11. air-count,k This allows for the determination of the required seawater flow rate for this layer. Based on the actual required seawater flow rate, a signal is transmitted to the corresponding water pumps and valves. The water pumps start, and the low-temperature seawater outside the hull flows through the main inlet pipe 41 to the branch cooling water pipes (i.e., the first hollow plate 1) inside the cabin. The cooling seawater flows in the branch pipes, exchanges heat with the outside through the pipe walls, absorbs heat, and then converges to the main outlet pipe 42 and is discharged overboard. The flow rate of the cooling water pipes is automatically adjusted according to the value received from the space temperature sensor 11.

[0111] By employing the above technical solution, for the battery compartment cooling system in any embodiment of the first aspect, by accurately acquiring the lowest space temperature of each layer of the accommodating space corresponding to each first hollow panel, it is possible to achieve precise stratified monitoring of the temperature status of each layer of battery packs. This allows for stratified cooling control of each layer of battery packs: maintaining the seawater at its original state when the temperature meets the standard, and adjusting the seawater flow rate in the corresponding first hollow panel in a timely manner when the temperature is too high, without directly increasing the seawater flow rate in all first hollow panels. This helps to reduce energy consumption while ensuring cooling efficiency, effectively avoiding the impact of localized high temperatures on the battery pack's lifespan, and reducing safety risks. The above control method not only ensures the uniformity and reliability of cooling for each layer of battery packs but also dynamically adjusts the flow rate according to actual temperature requirements, significantly improving the energy efficiency and adaptability of the cooling system, and further enhancing the intelligence and practicality of the battery compartment cooling system.

[0112] Furthermore, in the above embodiment, adjusting the flow state and flow rate of seawater within the first hollow plate corresponding to each layer of the containment space in step S22 specifically includes:

[0113] The flow of seawater within the first hollow plate is controlled, and the required seawater flow rate for the first hollow plate is determined according to the following formulas 1 and 2:

[0114] (Formula 1);

[0115] (Formula 2);

[0116] in, The seawater flow rate required for the first hollow plate. The highest space temperature, This is the normal space temperature threshold. The first cooling coefficient, It is 700-830. The density of seawater, The specific heat capacity of seawater;

[0117] The flow rate of seawater within the first hollow plate is adjusted based on the seawater flow rate. This is achieved by introducing a first cooling coefficient. This allows for more accurate calculation of the heat generated by the environment surrounding the battery pack, which in turn enables precise calculation of the seawater flow required for each layer of the first hollow panel. This allows for precise temperature control of each layer's containment space, helping to balance the overall energy consumption and cooling efficiency of the battery compartment cooling system.

[0118] In one more specific embodiment, For example, it is 780.

[0119] Furthermore, in the above embodiments, reference is made to... Figure 7 The battery compartment cooling control method also includes:

[0120] S3: Obtain the lowest battery pack temperature for each battery pack layer corresponding to each auxiliary cooling water pipe in the battery compartment cooling system.

[0121] S4: Determine whether the lowest battery pack temperature is not higher than the normal battery pack temperature threshold; if yes, then execute S41: maintain the seawater in the auxiliary cooling water pipe in the preset initial state; if no, then execute S42: adjust the flow state and flow rate of seawater in the auxiliary cooling water pipe corresponding to each layer of the containment space until the lowest battery pack temperature is not higher than the normal battery pack temperature threshold.

[0122] Specifically, multiple battery pack temperature sensors can be installed at the location of each battery pack layer in the battery compartment cooling system. (See also...) Figure 1 and combined Figure 3 For example, the k-th layer can accommodate n battery packs, and correspondingly, n battery pack temperature sensors can be installed. Let T be the temperature of each battery pack temperature sensor in the k-th layer. i Where i = 1, 2, ..., n, then the calculated temperature T of the battery pack in the k-th layer is... bat-count,k =max(T1,T2,T3,...T j ,...T n ), Battery pack calculated temperature T bat-count,k This refers to the highest battery pack temperature of each battery layer. The normal battery pack temperature threshold can be set as a constant T. air-set This threshold can be determined based on the performance and parameters of the battery pack, for example, it can be in the range of 20-30℃. In this embodiment, the normal battery pack temperature threshold can be set to 26℃.

[0123] The preset initial state mentioned in step S41 is the same as the preset initial state mentioned in step S2, and will not be repeated here. In step S42, flow control can be achieved through a water pump (e.g., auxiliary water pump 7) and a control valve (e.g., second one-way control valve 71). When the preset initial state refers to seawater flowing at a preset minimum heat dissipation flow rate, the preset minimum heat dissipation flow rate corresponding to the seawater entering the auxiliary cooling water pipe can be the same as or different from the preset minimum heat dissipation flow rate corresponding to the seawater entering the first hollow plate, depending on actual needs.

[0124] Continue to combine Figures 1-3 For example, when the temperature of any battery pack temperature sensor 12 is greater than the normal battery pack temperature threshold T bat-set At that time, the central processing unit will calculate the battery pack calculated temperature T of the battery pack in the k-th layer of the housing space corresponding to this battery pack temperature sensor 12. bat-count,kThis allows for the determination of the required seawater flow rate for this layer. Based on the actual required seawater flow rate, a signal is transmitted to the corresponding water pump and valve. The water pump starts, and the low-temperature seawater outside the hull is diverted through the auxiliary inlet pipe 61 to the branch cooling water pipes (i.e., auxiliary cooling water pipes 6) inside the cabin. The cooling seawater flows in the branch pipes, exchanges heat with the outside through the pipe walls, absorbs heat, and then converges to the auxiliary outlet pipe 62 and is discharged overboard. The flow rate of the cooling water pipes is automatically adjusted according to the value received from the battery pack temperature sensor 12.

[0125] This configuration allows for the use of auxiliary cooling water pipes to cool the battery pack from different directions, and enables targeted control of the seawater flow rate in the auxiliary cooling water pipes corresponding to each battery pack layer, contributing to a more uniform temperature distribution. Furthermore, by combining the auxiliary cooling water pipes and the first hollow plate, and controlling the seawater flow rate for each based on the temperature of the battery pack or the temperature of the containment space, targeted cooling of each containment space and the battery packs within it can be achieved, improving cooling efficiency while keeping energy consumption within a reasonable range. This combination further enhances the overall system's operational reliability and ease of use.

[0126] Furthermore, in the above embodiments, adjusting the flow rate of seawater in the auxiliary cooling water pipe in step S42 specifically includes:

[0127] The required seawater flow rate for the auxiliary cooling water pipes is determined using the following formulas 3 and 4:

[0128] (Formula 3);

[0129] (Formula 4);

[0130] in, To assist the cooling water pipes with the required seawater flow rate, The highest battery pack temperature, This is the normal battery pack temperature threshold. The second cooling coefficient, It is 700-830. The density of seawater, The specific heat capacity of seawater;

[0131] Adjust the seawater flow rate in the auxiliary cooling water pipe based on the seawater flow rate until the highest battery pack temperature does not exceed the normal battery pack temperature threshold.

[0132] By introducing a second cooling coefficient in the above manner This allows for more accurate calculation of the heat generated during battery pack operation, which in turn enables precise calculation of the seawater flow required for each auxiliary cooling water pipe, thereby achieving precise temperature control for each battery pack layer. This helps to balance the overall energy consumption and cooling efficiency of the battery compartment cooling system.

[0133] In one more specific embodiment, For example, it is 780.

[0134] Thirdly, refer to Figure 8 This utility model discloses a battery compartment cooling control device 01, which controls the battery compartment cooling system in any of the aforementioned first aspects to cool the battery compartment, with seawater flowing through the first hollow plate at a preset flow rate. The battery compartment cooling control device 01 can cool the battery compartment using the battery compartment cooling control method in any of the aforementioned second aspects. The battery compartment cooling control device 01 includes a temperature detection module 011 and a flow control module 012.

[0135] The temperature detection module 011 is used to obtain the lowest space temperature of each layer of the containment space corresponding to each first hollow plate in the battery compartment cooling system.

[0136] The flow control module 012 is used to determine whether the minimum space temperature is not higher than the normal space temperature threshold; if so, the seawater is maintained to circulate in the first hollow plate at a preset flow rate; if not, the flow rate of the seawater in the first hollow plate is adjusted until the minimum space temperature is not higher than the normal space temperature threshold.

[0137] By adopting the above technical solution, for the battery compartment cooling system in any embodiment of the first aspect, the battery compartment cooling control device can accurately monitor the temperature status of each layer of battery packs by precisely acquiring the lowest space temperature of each layer corresponding to each first hollow plate. This allows for layered cooling control of each battery pack layer: maintaining a preset seawater flow rate when the temperature meets the standard, and adjusting the seawater flow rate in the corresponding first hollow plate when the temperature is too high, without directly increasing the seawater flow rate in all first hollow plates. This helps to reduce energy consumption while ensuring cooling efficiency, effectively avoiding the impact of localized high temperatures on the battery pack's lifespan, and reducing safety risks. The above control method ensures the uniformity and reliability of cooling for each layer of battery packs, and dynamically adjusts the flow rate according to actual temperature requirements, significantly improving the energy efficiency and adaptability of the cooling system, further enhancing the intelligence and practicality of the battery compartment cooling system.

[0138] Fourthly, refer to Figure 9This utility model discloses an electronic device 02, which includes a processor 022 and a memory 021. The memory 021 stores at least one instruction, which, when executed by the processor 022, implements the battery compartment cooling control method in any of the embodiments of the second aspect described above. The memory 021 may include, for example, system memory, a fixed non-volatile storage medium, etc. The system memory may store, for example, an operating system, application programs, a boot loader, and other programs.

[0139] By adopting the above technical solution, for the battery compartment cooling system in any embodiment of the first aspect, the electronic device 02 can accurately monitor the temperature status of each layer of battery packs by precisely acquiring the lowest space temperature of each layer corresponding to each first hollow plate. This allows for layered cooling control of each battery pack layer: maintaining a preset seawater flow rate when the temperature meets the standard, and adjusting the seawater flow rate in the corresponding first hollow plate when the temperature is too high, without directly increasing the seawater flow rate in all first hollow plates. This helps to reduce energy consumption while ensuring cooling efficiency, effectively avoiding the impact of localized high temperatures on the battery pack's lifespan, and reducing safety risks. The above control method ensures the uniformity and reliability of cooling for each layer of battery packs, and dynamically adjusts the flow rate according to actual temperature requirements, significantly improving the energy efficiency and adaptability of the cooling system, further enhancing the intelligence and practicality of the battery compartment cooling.

[0140] Fifthly, embodiments of this utility model disclose a computer-readable storage medium storing at least one instruction, which, when executed, implements the battery compartment cooling control method in any of the embodiments of the second aspect.

[0141] By employing the above technical solution, for the battery compartment cooling system in any embodiment of the first aspect, the computer-readable storage medium can accurately acquire the lowest space temperature of each layer of the battery pack corresponding to each first hollow plate, enabling precise layered monitoring of the temperature status of each battery pack layer. This allows for layered cooling control of each battery pack layer: maintaining a preset seawater flow rate when the temperature meets the standard, and adjusting the seawater flow rate in the corresponding first hollow plate when the temperature is too high, without directly increasing the seawater flow rate in all first hollow plates. This helps to reduce energy consumption while ensuring cooling efficiency, effectively avoiding the impact of localized high temperatures on the battery pack's lifespan, and reducing safety risks. The above control method ensures both the uniformity and reliability of cooling for each battery pack layer, and dynamically adjusts the flow rate according to actual temperature requirements, significantly improving the energy efficiency and adaptability of the cooling system, further enhancing the intelligence and practicality of the battery compartment cooling system.

[0142] Sixthly, embodiments of the present invention disclose a ship including the battery compartment cooling system described in any of the embodiments of the first aspect.

[0143] By adopting the above technical solution and using the aforementioned battery compartment cooling system in a ship, multiple first hollow plates and multiple second hollow plates are fixedly connected and fluidly communicated to form the battery rack body. This achieves both the regular and high-density arrangement of the battery pack to efficiently utilize the internal space of the battery compartment, and the battery rack body also serves the dual functions of structural support and cooling channels. Low-temperature seawater can flow smoothly within all hollow plates, achieving efficient global cooling of the battery pack and battery compartment space. This helps ensure uniform temperature distribution in all areas of the battery pack and battery compartment. The above structure eliminates the need for additional independent cooling pipes and battery pack support frames, simplifying the structure of the entire battery compartment cooling system. It can be adapted to various battery compartment specifications, reducing costs. Furthermore, seawater is a widely available and inexpensive cooling medium. Especially when the ship is sailing, seawater can continuously flow within the first and second hollow plates, significantly improving the system's practicality and economy.
