Description

Technical Field

[0001] This application relates to the field of battery compartment technology, and in particular to a ventilation device for a battery compartment of a new energy ship. Background Technology

[0002] In the field of new energy ships, the battery compartment, as a core component of the ship's power system, requires a safe and stable operating environment. The battery compartment typically needs to maintain good ventilation to ensure effective heat dissipation of the battery packs during operation and prevent safety accidents caused by overheating.

[0003] Existing battery compartment ventilation systems often employ a single intake and exhaust pattern, with inefficiently designed inlet and exhaust vents that result in poor airflow and dead zones. This not only affects the heat dissipation of the battery pack but may also accelerate battery aging and reduce its lifespan. Furthermore, some ventilation systems neglect airflow uniformity and stability during design and manufacturing, leading to uneven temperature distribution within the compartment and further exacerbating safety hazards.

[0004] Secondly, in terms of ease of maintenance, the number of ventilation devices in the existing battery compartment is relatively limited. If this ventilation equipment malfunctions and needs to be shut down for repair or replacement, the entire battery compartment ventilation system will be affected, resulting in a decrease in the heat dissipation effect of the battery compartment.

[0005] To address the aforementioned issues, a ventilation device for the battery compartment of new energy ships is now designed. Utility Model Content

[0006] This application provides a ventilation device for the battery compartment of a new energy ship, which solves the problem that existing battery compartment ventilation devices in the related technology often adopt a single air intake and exhaust mode, and the layout of the air intake and exhaust is not reasonable enough, resulting in poor air flow in the compartment and the existence of ventilation dead zones.

[0007] Firstly, a ventilation device for the battery compartment of a new energy ship is provided, comprising:

[0008] The cabin has several air supply components on one side, which are distributed along the length of the cabin. The air supply components are used to supply gas into the cabin. Several exhaust fans are provided on the other side of the cabin, which are used to extract gas from the cabin.

[0009] The air supply assembly includes a housing mounted on the cabin body, a fan installed inside the housing, an air supply pipe connected to the other end of the housing, and a filter installed inside the air supply pipe.

[0010] In some embodiments, the cabin is provided with a plurality of mounting frames, the shell is disposed on the corresponding mounting frame, a protective net is provided inside the mounting frame, and the shell is open on the side near the mounting frame.

[0011] In some embodiments, the air supply pipe is zigzag-shaped, and a demister is provided in the middle of the air supply pipe.

[0012] In some embodiments, the filter section includes a perforated metal mesh disposed at one end of the air supply pipe, a non-woven fabric filter screen disposed inside the air supply pipe, and an installation hole located above the non-woven fabric filter screen on the air supply pipe, with a sealing cap connected to the installation hole by bolts.

[0013] In some embodiments, the exhaust fan includes an exhaust pipe and a housing connected to each other. The housing is disposed on the cabin body, and the side of the housing connected to the cabin body is open. A second fan is disposed inside the housing, and the housing is connected to the exhaust pipe.

[0014] In some embodiments, a filter screen is provided at the other end of the exhaust pipe.

[0015] This application provides a ventilation device for the battery compartment of a new energy ship. By arranging multiple air supply components and exhaust fans along the length of the compartment, this device achieves uniform distribution and efficient circulation of air inside the compartment. This not only improves ventilation efficiency but also ensures sufficient air circulation in every corner of the compartment, effectively reducing the temperature of the battery pack and extending the battery's lifespan.

[0016] By employing a redundant design with multiple air supply components and exhaust fans, this device can still maintain a certain ventilation capacity even if a single component fails, thereby improving the reliability and stability of the entire ventilation system. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] This application provides a ventilation device for the battery compartment of a new energy ship, which can solve the problem that existing battery compartment ventilation devices in the related technology often adopt a single air intake and exhaust mode, and the layout of the air intake and exhaust is not reasonable, resulting in poor air flow in the compartment and the existence of ventilation dead zones.

[0026] Please see Figures 1-3 A ventilation device for a battery compartment of a new energy ship includes: a compartment 1, on one side of the compartment 1 are several air supply components 2, which are distributed along the length of the compartment 1 and are used to supply gas into the compartment 1; on the other side of the compartment 1 are several exhaust fans 3, which are used to extract gas from the compartment 1; the air supply components 2 include a housing 21 disposed on the compartment 1, a fan 22 disposed inside the housing 21, and an air supply pipe 23 connected to the other end of the housing 21, and a filter section 24 disposed inside the air supply pipe 23.

[0027] The chamber 1, serving as the main structure of the battery compartment, provides a sealed working environment for the battery pack. To maintain air circulation within the chamber, multiple air supply components 2 are installed along the length of one side of the chamber 1. These air supply components 2 operate via internal fans 22, drawing fresh external air into the chamber 1. Simultaneously, to prevent impurities or particulate matter in the intake air from damaging the battery pack, a filter 24 is specially installed inside the air supply pipe 23 to filter and purify the intake air.

[0028] On the other side of the cabin 1, the device is equipped with multiple exhaust fans 3. These exhaust fans 3 draw air from the cabin, forming an airflow path opposite to the air supply assembly 2, ensuring continuous and efficient air circulation within the cabin. When the fan 22 and the exhaust fans 3 operate simultaneously, a stable airflow field is formed inside the cabin 1, effectively removing heat and harmful gases generated by the battery pack, maintaining a safe and stable environment inside the cabin.

[0029] By arranging multiple air supply components 2 and exhaust fans 3 along the length of the cabin 1, this device achieves uniform distribution and efficient circulation of air within the cabin. This not only improves ventilation efficiency but also ensures sufficient airflow to every corner of the cabin, effectively reducing the temperature of the battery pack and extending its lifespan.

[0030] By employing a redundant design with multiple air supply components 2 and exhaust fans 3, this device can still maintain a certain ventilation capacity even when a single component fails, thereby improving the reliability and stability of the entire ventilation system.

[0031] The filter section 24 installed inside the air supply pipe 23 effectively filters out impurities and particulate matter in the air, preventing them from entering the battery compartment 1 and damaging the battery pack. This not only improves the cleanliness of the battery compartment but also reduces safety hazards caused by impurities.

[0032] Both the air supply component 2 and the exhaust fan 3 of this device adopt a modular design, which facilitates individual disassembly and replacement. This greatly reduces maintenance costs and allows maintenance personnel to maintain and repair individual components without affecting the normal operation of the entire ventilation system.

[0033] Specifically, in this embodiment, the cabin 1 is provided with a plurality of mounting frames 4, the shell 21 is mounted on the corresponding mounting frame 4, the mounting frame 4 is provided with a protective net 7, and the shell 21 is open on the side near the mounting frame 4.

[0034] On one side of the cabin 1, multiple mounting frames 4 are arranged along its length. The mounting frames 4 not only provide a stable mounting position for the air supply assembly 2, but also further enhance the safety of the ventilation device through the protective net 7 installed inside. The protective net 7 can effectively prevent large external debris or animals from entering the air supply assembly 2, avoiding damage to the fan 22 or the air supply pipe 23.

[0035] The housing 21 of the air supply assembly 2 is mounted on the corresponding mounting frame 4 by bolts or other fastening methods, and the side of the housing 21 closest to the mounting frame 4 is open. This design allows the fan 22 to smoothly draw outside air into the housing 21 and deliver it into the cabin 1 through the air supply pipe 23. The filter section 24 inside the air supply pipe 23 filters and purifies the drawn-in air, ensuring the air quality entering the cabin 1.

[0036] On the other side of the cabin 1, multiple exhaust fans 3 are installed. These exhaust fans 3 draw in air from the cabin and create convection with the air supply components 2 to achieve continuous air circulation inside the cabin. When the fan 22 and the exhaust fans 3 work simultaneously, a stable airflow field will be formed inside the cabin 1, effectively removing the heat and harmful gases generated by the battery pack.

[0037] Specifically, the air supply pipe 23 is zigzag-shaped, and a demister 5 is provided in the middle of the air supply pipe 23.

[0038] The main function of the demister 5 is to remove moisture and tiny droplets from the air, preventing them from entering the compartment 1 and damaging the battery pack. The demister 5 is particularly important in humid or rainy environments. It effectively prevents battery pack corrosion or short circuits caused by excessive air humidity. The air supply pipe 23 features a zigzag design to prevent backflow of filtered water mist.

[0039] In one embodiment, such as Figure 5 As shown, the filter section 24 includes a perforated metal mesh 241 disposed at one end of the air supply pipe 23. A non-woven fabric filter screen 242 is disposed inside the air supply pipe 23. An installation hole is opened on the air supply pipe 23 above the non-woven fabric filter screen 242. A sealing cap 243 is connected to the installation hole by bolts.

[0040] The fan 22 of the air supply assembly 2 draws in outside air through the opening in the housing 21. The air first passes through the perforated metal mesh 241, which is a preliminary filtration barrier that can prevent larger particles and impurities from entering the air supply pipe 23.

[0041] The air, after being initially filtered by the perforated metal mesh 241, continues to enter the air supply pipe 23. Inside the air supply pipe 23, a non-woven fabric filter 242 is installed. This is a more refined filtration barrier that can further filter out dust, fine particulate matter, and other impurities in the air, ensuring air quality.

[0042] By further improving the air filtration and defogging capabilities, a cleaner, safer, and more reliable working environment is provided for the battery compartments of new energy vessels. At the same time, the device also features excellent ease of maintenance and airflow uniformity, ensuring the long-term stable operation of the ventilation system.

[0043] In one embodiment, such as Figure 4 As shown, the exhaust fan 3 includes an exhaust pipe 31 and a housing 32 connected to each other. The housing 32 is mounted on the cabin 1. The side of the housing 32 connected to the cabin 1 is open. A second fan 33 is installed inside the housing 32. The housing 32 is connected to the exhaust pipe 31.

[0044] The outer casing 32 of the exhaust fan 3 is securely mounted on the chamber 1, and the side connected to the chamber 1 is open. This design ensures that the exhaust fan 3 can smoothly draw air from inside the chamber 1. Inside the outer casing 32, a second fan 33 is installed. When the second fan 33 is started, it generates a strong suction force, drawing air from inside the chamber into the outer casing 32.

[0045] The air drawn into the outer shell 32 is then directed to the exhaust pipe 31. The exhaust pipe 31 is connected to the interior of the outer shell 32, forming a smooth air passage. In this way, air can be smoothly discharged from the cabin 1 along the exhaust pipe 31 under the action of the fan 33.

[0046] When the fan 22 of the air supply assembly 2 and the fan 33 of the exhaust fan 3 operate simultaneously, they create a stable airflow field inside the cabin 1. The air supply assembly 2 continuously supplies outside air into the cabin, while the exhaust fan 3 continuously extracts air from the cabin, creating convection. This convection helps to quickly remove the heat and harmful gases generated by the battery pack, maintaining a clean and suitable environment inside the cabin.

[0047] Furthermore, a filter screen 6 is provided at the other end of the exhaust pipe 31.

[0048] In the further optimized ventilation device for the battery compartment of new energy ships, a filter screen 6 is added to the other end of the exhaust pipe 31. This not only retains the efficient exhaust function of the original exhaust fan 3, but also protects the exhaust pipe 31 and the interior of the outer shell 32, increasing the safety of the entire ventilation system.
