[0030] As mentioned in the background, the existing battery pack cooling method on the ship is mainly to use the water cooler to cool the cooling liquid and then send it into the ship to cool the battery of the ship, but this method has complex cooling liquid conveying pipeline and is easy to leak cooling liquid; in addition, the cooling method using the water cooler also needs a water cooler unit to cool the cooling liquid, which has high cost. Therefore, the present application provides a ship, which sets the battery pack at the bottom of the hull and seals it, at this time, the bottom of the battery pack is directly in contact with the water surface to achieve cooling, so that the production cost is reduced and the heat dissipation efficiency of the battery on the ship is improved. The ship of the present application will be described in detail below with reference to the accompanying drawings.

[0031] Referring to Figures 1 to 3 According to the embodiments of the present application, a ship is provided. Specifically, the ship includes a hull 10 and a battery pack 20.

[0032] In this embodiment, the bottom of the hull 10 is provided with a receiving cavity 11 and an opening 12, the opening 12 communicates with the receiving cavity 11; the battery pack 20 is installed in the receiving cavity 11, the battery pack 20 includes a battery module 21 and a closed shell part 22, the battery module 21 is arranged inside the shell part 22, and the shell part 22 is at least partially located at the opening 12 and seals the opening 12.

[0033] In the embodiment, the battery pack 20 is installed in the accommodating cavity 11 from the opening 12 by setting the accommodating cavity 11 and the opening 12 on the bottom of the hull 10, and the opening 12 communicates with the accommodating cavity 11. At this time, the bottom of the battery pack 20 can be used as part of the bottom of the hull 10, and when the ship is in water, the bottom of the battery pack 20 is directly in contact with water, and water can directly cool the battery pack 20, thereby reducing the production cost. Specifically, in the embodiment, the battery pack 20 includes a battery module 21 and a closed shell part 22, the battery module 21 is arranged inside the shell part 22, and the closed shell part 22 is made of high thermal conductivity material, so that the closed shell part 22 not only reduces the adverse effects of the external environment on the battery module 21, but also timely transfers the heat generated by the battery module 21 to the external environment. In addition, the shell part 22 is at least partially located at the opening 12 and seals the opening 12, so that water and other substances cannot enter the accommodating cavity 11 of the hull 10, thereby improving the working efficiency of the battery and ensuring the system stability of the ship.

[0034] That is, the ship in the embodiment eliminates the complex cooling liquid delivery pipeline and water cooler required when the water cooler is used in the prior art, avoids the risk of leakage of Freon in the cooling liquid and the water cooler, and reduces the production cost. The ship in the embodiment improves the cooling efficiency of the battery pack 20 and reduces the production cost under a simple structure design.

[0035] As shown in Figures 1 to 3 , the opening 12 is arranged on the bottom of the hull 10 to facilitate the installation of the battery pack 20. Specifically, the installation of the battery pack 20 on the bottom of the hull 10 includes two cases: the bottom of the battery pack 20 is flush with the bottom of the hull 10 or the bottom of the battery pack 20 at least partially protrudes from the bottom of the hull 10 from the opening 12. By using the two installation methods, direct use of water flow to cool the battery pack 20 can be achieved. The installation of the battery pack 20 is selected according to actual needs, and is not specifically limited in the application.

[0036] As shown in Figure 2 and Figure 3 , the ship further includes a sealing part 30 arranged between the hull 10 and the battery pack 20 to prevent substances outside the hull 10 from entering the accommodating cavity 11 from the gap between the opening 12 and the battery pack 20. By arranging the sealing part 30 in this way, when the ship is put into water, the sealing part 30 can effectively prevent water from entering the accommodating cavity 11 of the hull 10, thereby avoiding the influence of water on the safety and working efficiency of the battery pack 20, and improving the normal operation of the ship.

[0037] Further, the sealing part 30 can be a sealing glue layer, a sealing gasket, or both. In the present embodiment, the battery pack 20 is installed at the bottom of the ship body 10, and is directly in contact with water, so waterproof measures are very important. Specifically, a sealing glue or a sealing gasket can be arranged between the ship body 10 and the battery pack 20, so that a good sealing structure can prevent water from entering the accommodating cavity 11 of the ship body 10 or the inside of the battery pack 20, protect the electrical components from damage, and avoid short circuit or other electrical faults. For example, the sealing glue can be polyurethane sealing glue, modified silane sealing glue, epoxy resin sealing glue, etc.; the sealing gasket can be EDPM (ethylene-propylene-diene rubber) sealing gasket, silicone sealing gasket, polyurethane sealing gasket, modified silane sealing gasket, etc. Whether it is a sealing glue or a sealing gasket, when selecting, the special requirements of the use environment of the ship should be considered, including waterproof, moisture-proof, corrosion-resistant, vibration-resistant, and impact-resistant, etc. In the present embodiment, the type of the sealing part 30 is not specifically limited, and is determined according to the actual working conditions and technical requirements in the actual production process.

[0038] Again referring to Figures 1 to 3 In the present application, the accommodating cavity 11 has a first side wall 111 close to the bottom of the ship body 10, and the opening 12 is arranged on the first side wall 111, which is beneficial to make the battery pack 20 directly contact with water from the opening 12. At the same time, the annular outer flange 23 is arranged on the outer periphery of the shell part 22, and the shell part 22 is fixed to the first side wall 111 through the annular outer flange 23. In this way, the installation stability of the battery pack 20 and the ship body 10 is strengthened, and the working efficiency of the battery pack 20 is further improved. In the present embodiment, the sealing part 30 is arranged between the annular outer flange 23 and the first side wall 111, which can be a sealing glue or a sealing gasket. The annular outer flange 23 increases the contact area with the first side wall 111, so that the sealing material can better fit the first side wall 111, form a more effective water-tight barrier, and further prevent water from entering the inside of the battery pack 20. Specifically, the shape of the sealing part 30 between the annular outer flange 23 and the first side wall 111 can be a flat plate, or a 7-shaped, and of course in other embodiments of the present application, it can also be other shapes, as long as it is within the protection scope of the present application in the transformation of the present embodiment.

[0039] Further, the annular outer flange 23 and the sealing part 30 are adhered by a glue layer and fixed to the first side wall 111 by a locking member. Alternatively, the annular outer flange 23 and the sealing part 30 are directly fixed to the first side wall 111 by a locking member. In the embodiment, the annular outer flange 23, the sealing part 30 and the first side wall 111 are fixed by the locking member to ensure the sealing effect of the ship body 10 and the battery pack 20 and improve the mechanical stability of the ship as a whole. For example, the locking member in the embodiment includes a bolt and a nut, a T-shaped groove and a T-shaped bolt, a quick-lock buckle, a welding fixation and the like. In the embodiment, a flange surface is preferably used in cooperation with the bolt and the nut. The flange surface provides a flat contact surface to make the sealing part 30 better achieve the setting. The bolt and the nut exert a clamping force so that the sealing gasket or the sealing glue can be uniformly pressed, thereby improving the sealing effect.

[0040] Further, the shell part 22 includes a bottom shell 221 and an upper cover 222. The shell part 22 is arranged as a detachable bottom shell 221 and an upper cover 222. The upper cover 222 is buckled on the bottom shell 221, and the battery module 21 is installed in the bottom shell 221. Specifically, the side of the bottom shell 221 close to the upper cover 222 is provided with a first annular sealing flange 2211, and the side of the upper cover 222 close to the bottom shell 221 is provided with a second annular sealing flange 2221. The first annular sealing flange 2211 and the second annular sealing flange 2221 are fixedly connected and form an annular outer flange 23. The annular sealing flange is beneficial to realize the sealing of the battery pack 20. It is worth noting that a sealing layer 50 is arranged between the first annular sealing flange 2211 and the second annular sealing flange 2221. The sealing layer 50 can effectively prevent water and other substances in the external environment from entering the inside of the shell part 22, and avoid the risk of short circuit of the battery module 21. Specifically, the sealing layer 50 can be a sealing gasket or a sealing glue. In the embodiment, the sealing layer 50 is preferably a sealing gasket, which is convenient to operate when the battery module 21 needs to be replaced.

[0041] As Figure 3As shown, a heat-conducting layer 40 is arranged between the battery module 21 and the bottom shell 221. When the battery module 21 is installed in the bottom shell 221, the heat-conducting layer 40 is arranged in the bottom shell 221, which can provide a more uniform heat transfer path, reduce thermal resistance, and facilitate the timely transfer of heat generated by the battery module 21 to the bottom shell 221. Through the direct contact of the outside of the bottom shell 221 with water, heat exchange is achieved, so that the battery pack 20 is cooled in time, which helps to keep the working temperature of the battery pack 20 within a safe range, prevents overheating, prolongs the service life of the battery, and further enhances the system safety and mechanical stability of the ship. Generally, the contact surface between the battery module 21 and the bottom shell 221 is irregular, with tiny gaps or bubbles. The heat-conducting layer 40 can fill these gaps and provide better mechanical support, reducing the impact of vibration and impact on the battery pack 20. In this embodiment, the heat-conducting layer 40 can reduce production costs, eliminate the design of traditional complex water-cooling pipes, and reduce the space occupation in the battery pack 20, thereby improving the compactness of the system.

[0042] Further, the heat-conducting layer 40 includes a heat-conducting silica gel layer, which can also be a heat-conducting pad. Common materials for the heat-conducting layer 40 include heat-conducting silicone grease, heat-conducting pads, heat-conducting gels, and heat-conducting phase-change materials. The heat-conducting silica gel layer has good heat conductivity and fluidity, and is suitable for filling tiny gaps. The heat-conducting pad has uniform thickness and is easy to install, and is suitable for larger contact surfaces and has good mechanical stability and durability. In this application, the heat-conducting layer 40 is not specifically limited, and can be selected according to actual needs during production.

[0043] In this embodiment, the battery pack 20 and the opening 12 are both multiple, and the multiple battery packs 20 and the multiple openings 12 are arranged in a one-to-one correspondence. Multiple openings 12 can be arranged in the accommodation cavity 11. For example, the number of battery packs 20 can be 1, 2, 3, 4, etc.; the number of openings 12 can be 1, 2, 3, 4, etc.; and the specific number is not limited. However, the number of battery packs 20 and openings 12 needs to be arranged in a one-to-one correspondence, so that the battery pack 20 on the ship can be directly contacted with water through the opening 12 to achieve cooling, thereby prolonging the service life of the battery pack 20. The specific number of battery packs 20 and openings 12 is not specifically limited in this application, and can be determined according to actual work needs. Figure 1 and Figure 2 The case where the battery pack 20 and the opening 12 are both two is shown in FIGS. 1 and 2.

[0044] According to the above embodiment, it can be known that the ship of the present application realizes the cooling of the battery pack 20 by arranging the opening 12 on the bottom of the ship body 10 and installing the battery pack 20 at the opening 12, so that the bottom of the battery pack 20 is directly in contact with water. In the battery pack 20, the heat-conducting layer 40 is arranged between the battery module 21 and the bottom shell 221, which can effectively transfer the heat generated by the battery module 21 to the bottom shell 221. In actual installation, the bottom of the battery pack 20 is flush with the bottom of the ship body 10 or at least partially protrudes from the opening 12 to the bottom of the ship body 10, which is beneficial to the cooling of the battery pack 20 by water. In addition, the sealing part 30 is arranged between the annular outer flange 23 of the battery pack 20 and the first side wall 111 of the ship body 10, which improves the sealing effect and prevents water and other substances from entering the accommodating cavity 11 through the gap between the battery pack 20 and the ship body 10, thereby adversely affecting the battery pack 20.

[0045] In this way, the bottom shell 221 of the battery pack 20 can be directly in contact with the water surface, and the cooling of the battery pack 20 is realized by direct contact with water, so that a complex water cooling pipeline and a water cooling machine do not need to be arranged, the risk of leakage of the cooling liquid is reduced, the production cost is reduced, the heat dissipation efficiency of the battery pack 20 is improved, and the service life of the battery pack 20 is prolonged, thereby ensuring the system stability of the ship.
