Description

Technical Field

[0001] The present invention relates to the technical field of lithium batteries, and in particular to a solid-state lithium battery with a heat dissipation structure for ship propulsion. Background Art

[0002] During the operation of a ship, it is usually accompanied by high temperature, high humidity and high-frequency vibration. Such a harsh environment places extremely high demands on its internal power batteries. Currently, solid-state lithium batteries are widely used in the ship field because they use solid electrolytes instead of flammable liquid electrolytes, which can effectively avoid risks such as leakage and thermal runaway.

[0003] During the voyage of a ship, the power battery needs to discharge at a high rate for a long time, which will cause a sharp increase in the heat generated inside the battery pack. Therefore, existing solid-state lithium batteries for ships are equipped with liquid cooling or air cooling heat dissipation systems. When air cooling is used, due to the high humidity in the environment where the ship is located and the salt mist in the air, the gas containing salt mist will corrode the surface of the lithium battery and damage the structure of the lithium battery after being in contact with the lithium battery terminal for a long time. In addition, if the salt mist gas is in contact with the lithium battery terminal for a long time, the chloride ions in the salt mist will penetrate the metal surface protective layer, causing electrochemical corrosion, resulting in rust, peeling or mechanical strength reduction on the terminal surface. The corrosion products or salt crystal layer will also increase the contact resistance, affecting the current transmission efficiency. In extreme cases, it will cause local overheating or connection interruption. Summary of the Invention

[0020] An investigation found that most existing lithium batteries for ships are cooled by air cooling during use. Due to the high humidity and salt spray content of the sea air, if the sea air comes into contact with the terminals of the lithium battery, it will corrode the terminals. At the same time, long-term contact between the sea air and the lithium battery will also cause corrosion to its surface, causing damage to the lithium battery and affecting its use.

[0021] Example 1

[0022] This embodiment discloses a solid-state lithium battery with a heat dissipation structure for ship propulsion, which has the function of protecting the connection terminals of the lithium battery, thereby reducing the probability of corrosion of the connection terminals of the lithium battery.

A plurality of air vents 303 are provided on both the front and rear sides of the fixed inner shell 3. The air vents 303 on one side are used for air intake, and the air vents 303 on the other side are used for air exhaust. All the air vents 303 are connected to the heat dissipation cavity 302. A lithium battery module 4 is installed in the packaging shell 301 on the fixed inner shell 3. The fixed inner shell 3 is used to protect the lithium battery module 4 and wrap the lithium battery module 4 to reduce the probability of corrosion on the surface of the lithium battery module 4. Two adjacent lithium battery modules 4 are electrically connected (such as Figure 2 As shown, several temperature sensors (not shown in the figure) are installed in the fixed inner shell 3. All temperature sensors are evenly distributed and detect the temperature in the adjacent area packaging shell 301 respectively. The terminal of the lithium battery module 4 is located in the sealed cavity between the fixed inner shell 3 and the sealing cover plate 2. In this way, the terminal of the lithium battery module 4 is shielded from contact with the sea breeze, thereby reducing the probability of corrosion. All lithium battery modules 4 are divided into five columns distributed in an array, and the lithium battery modules 4 in two adjacent columns are staggered (as shown in the figure). Figure 2 and Figure 4 As shown), this distribution is used to guide the sea breeze entering the heat dissipation cavity 302, thereby increasing the degree of chaos of the sea breeze in the heat dissipation cavity 302.

[0024] Please compare Figure 4-Figure 8, the mounting shell 1 is slidably connected with six first air guide plates 21 distributed in an array and six second air guide plates 22 distributed in an array, the first air guide plates 21 and the second air guide plates 22 are staggered, the first air guide plates 21 and the corresponding second air guide plates 22 are respectively located on the left and right sides of a corresponding column of lithium battery modules 4, a tension spring is provided between the first air guide plates 21 and the corresponding second air guide plates 22, the first air guide plates 21 and the corresponding second air guide plates 22 are used to guide part of the wind entering the heat dissipation cavity 302, and a gap is left between the first air guide plates 21 and the second air guide plates 22 and the corresponding packaging shell 301, which provides air flow for the sea breeze Dynamic space, so that this part of the sea breeze flows in accordance with the corresponding column of lithium battery modules 4, thereby improving the heat dissipation effect of the corresponding column of lithium battery modules 4, a gas flow channel is formed between the first wind guide plate 21 and the corresponding second wind guide plate 22, and a part of all the air outlets 303 on the same side are respectively connected to the gas flow channel formed by the first wind guide plate 21 and the corresponding second wind guide plate 22, so that the sea breeze dissipates heat for the lithium battery modules 4, and another part of all the air outlets 303 on the same side are respectively connected to the gas flow channel between the first wind guide plate 21 and the adjacent second wind guide plate 22 (the gas flow channel is located between two adjacent columns of lithium battery modules 4).

[0025] Please compare Figure 5 and Figure 7-Figure 9 The first air guide plate 21 and the corresponding second air guide plate 22 are fixedly connected to the away sides thereof with five heat dissipation protrusions 31 distributed in a linear array, which are used to increase the surface area of ​​the first air guide plate 21 and the second air guide plate 22 to facilitate the dissipation of heat thereon.

[0026] Please compare Figure 5-Figure 7 The outer side of the packaging shell 301 is fixedly connected to an array of heat dissipating fins 41, which are used to absorb the heat of the packaging shell 301 and release the heat, thereby enhancing the heat dissipation effect of the lithium battery module 4. The first air guide plate 21 and the corresponding second air guide plate 22 are jointly fixedly connected to a plurality of heat dissipating fins 42. The heat dissipating fins 42 are used to absorb the heat of the heat dissipating fins 41. The heat dissipating fins 41 and the heat dissipating fins 42 are both metal sheets and are elastic. The heat dissipating fins 41 are squeezed and contacted with the heat dissipating fins 42 between the corresponding first air guide plate 21 and the second air guide plate 22. The heat dissipating fins 41 and the corresponding heat dissipating fins 42 squeeze each other, causing the two to vibrate, thereby facilitating the shaking off of impurities on them.

[0027] The working principle of a solid-state lithium battery with a heat dissipation structure for ship propulsion in this embodiment is as follows: During the use of this lithium battery, all temperature sensors on the fixed inner shell 3 are turned on to detect the temperature of all lithium battery modules 4. When the temperature is detected to exceed the suitable temperature range of the lithium battery module 4, the heat dissipation system is turned on, and then the outside sea breeze enters the heat dissipation system.

[0028] The sea breeze enters the gas flow channel between the corresponding first air guide plate 21 and the corresponding second air guide plate 22 through the rectangular hole of the mounting shell 1 and the air outlet 303 on the front side of the fixed inner shell 3. Figure 6 The parts inside are described, and the sea breeze blowing from the back to the front is taken as an example. After entering the gas flow channel, the sea breeze continues to flow forward. After the sea breeze contacts the packaging shell 301 on the rear side, the sea breeze flows back to the left and right sides under the guidance of the first wind guide plate 21 and the corresponding second wind guide plate 22. At this time, the sea breeze flows along the gap between the first wind guide plate 21 and the corresponding second wind guide plate 22 and the packaging shell 301. In this process, the sea breeze blows on the outer surface of the packaging shell 301 to cool it down, and transfers the heat of the corresponding lithium battery module 4 through the packaging shell 301, thereby realizing heat dissipation of the lithium battery module 4.

[0029] When the sea breeze flows along the gap (along the side of the packaging shell 301 ), the flow area is reduced, so that the flow velocity of the sea breeze increases, thereby improving the efficiency of heat dissipation for the packaging shell 301 .

[0030] After the sea breeze flows to the front side of the packaging shell 301, the sea breezes on the left and right sides begin to flow in opposite directions and form a counterflow, so that the sea breezes on the left and right sides are mixed, improving the uniformity of the sea breeze temperature distribution and facilitating uniform heat dissipation of the packaging shell 301 in the middle.

[0031] After the sea breeze hits, it continues to flow forward along the gap and contacts the middle packaging shell 301. Then part of the sea breeze flows forward along the gap, and the other part of the sea breeze flows to the right along the gap. In the process, the middle packaging shell 301 and the corresponding lithium battery module 4 are cooled.

[0032] As the sea breeze continues to flow, when the sea breeze flows to the front side of the middle packaging shell 301, the two parts of the sea breeze collide and mix again. Then, one part of the sea breeze flows to the left along the gap, and the other part of the sea breeze flows forward along the gap. During this process, the two parts of the sea breeze jointly dissipate heat to the front packaging shell 301 and the corresponding lithium battery module 4.

[0033] After the two parts of sea breeze flow to the front side of the front packaging shell 301, the two parts of sea breeze flow in opposite directions and flow along the gas flow channels of the first wind guide plate 21 and the corresponding second wind guide plate 22, and then are discharged through the corresponding air outlet 303, thereby completing the heat dissipation operation of one column of packaging shells 301 and the corresponding lithium battery modules 4. The heat dissipation operation of the remaining columns of packaging shells 301 and the corresponding lithium battery modules 4 is consistent with the above process.

[0034] During the process of the above-mentioned sea breeze passing through the lithium battery, since the lithium battery module 4 is located in the corresponding packaging shell 301, it is not exposed to the sea breeze, thereby reducing the probability of the outer surface of the lithium battery module 4 being eroded by the sea breeze. At the same time, the connection terminal of the lithium battery module 4 is located in the sealed cavity between the sealing cover plate 2 and the fixed inner shell 3, and is not exposed to the wind entering the heat dissipation cavity 302, thereby preventing the connection terminal of the lithium battery module 4 from being eroded by the sea breeze.

[0035] As the sea breeze flows, it passes through the heat dissipation fins 41 and heat dissipation tabs 42, facilitating the heat dissipation of the packaging shell 301 and the lithium battery module 4. However, as the sea breeze passes through the heat dissipation fins 41 and heat dissipation tabs 42, it may cause slight corrosion to the heat dissipation fins 41 and heat dissipation tabs 42, thereby forming corrosion impurities on the surfaces of the heat dissipation fins 41 and heat dissipation tabs 42. These impurities attached to the surfaces of the heat dissipation fins 41 and heat dissipation tabs 42 may affect the heat dissipation efficiency of the heat dissipation fins 41 and heat dissipation tabs 42. To reduce this impact, the specific operations are as follows: During the navigation of the ship, the ship will shake due to the action of waves. At this time, the ship drives all the first wind guide plates 21 and the second wind guide plates 22 to shake left and right through the installation outer shell 1 and the fixed inner shell 3, so that the first wind guide plates 21 and the second wind guide plates 22 slide relative to each other with the fixed inner shell 3, and the tension spring between the first wind guide plates 21 and the corresponding second wind guide plates 22 will be stretched accordingly. The first wind guide plates 21 and the second wind guide plates 22 both drive the heat dissipation plates 42 thereon to move synchronously, and the heat dissipation plates 42 and the corresponding heat dissipation fins 41 slide relative to each other and squeeze each other (the two deflect each other to store force), and the impurities on them are separated by the relative squeezing and friction between the two. After the two lose contact, the heat dissipation plates 42 and the heat dissipation fins 41 will vibrate, which facilitates the separation of impurities on the surfaces of the two.

[0036] Example 2

[0037] During a ship's voyage, the external temperature will change (due to the temperature difference between day and night or regional environmental factors). When sailing in a low-temperature area (the low temperature refers to the suitable operating temperature for lithium batteries), the activity of lithium ions in the lithium battery decreases, resulting in the inability to fully release the discharge capacity within the normal voltage range, and a significant decrease in power output. The following solutions are proposed: This embodiment discloses a solid-state lithium battery for ship propulsion. Based on the embodiment 1, it also has the function of keeping the lithium battery warm to prevent the lithium battery from failing to work due to excessively low temperature.

[0038] Please compare Figure 4 、 Figure 9 and Figure 10The first air guide plate 21 and the second air guide plate 22 are both fixedly connected to a mounting block 51, and a magnetic block 52 is fixedly connected to the upper side of the mounting block 51. The fixed inner shell 3 is installed with six electromagnetic modules 53 distributed in an array, and the electromagnetic module 53 is located between the corresponding first air guide plate 21 and the second air guide plate 22, and the magnetic block 52 and the corresponding electromagnetic module 53 are magnetically attracted to each other. When the electromagnetic module 53 is energized, the electromagnetic module 53 generates a magnetic attraction force or a magnetic repulsion force, thereby controlling the movement of the corresponding first air guide plate 21 and the second air guide plate 22, so that the first air guide plate 21 and the corresponding second air guide plate 22 move in opposite directions or back to back. The newly introduced parts in this section are all located on the front side of the fixed inner shell 3. The newly introduced parts in this section are also provided on the rear side of the fixed inner shell 3 in the present invention, thereby ensuring the smooth movement of the first air guide plate 21 and the second air guide plate 22.

[0039] The working principle of a solid-state lithium battery for ship propulsion in this embodiment is as follows: During the navigation of the ship, the temperature sensor in the fixed inner shell 3 always detects the temperature of the adjacent lithium battery module 4. When the temperature is lower than the appropriate range, all the electromagnetic modules 53 are turned on (hereinafter described as the parts on the front side of the fixed inner shell 3). The electromagnetic modules 53 generate magnetic repulsion to Figure 9 For example, under the action of the magnetic repulsion of the electromagnetic module 53, the corresponding two magnetic blocks 52 move back to back, and the two magnetic blocks 52 drive the first air guide plate 21 and the second air guide plate 22 to move respectively. The first air guide plate 21 and the second air guide plate 22 move back to back, and the tension spring between the first air guide plate 21 and the second air guide plate 22 is stretched, so that the gap between the first air guide plate 21 and the left side of the corresponding packaging shell 301 gradually increases, and the gap between the second air guide plate 22 and the right side of the corresponding packaging shell 301 gradually increases, thereby increasing the flow space of the gap on the left and right sides of the packaging shell 301, thereby reducing the speed of the sea breeze flowing in the gap on the left and right sides of the packaging shell 301.

[0040] During the movement of the first air guide plate 21 and the second air guide plate 22, the distances between the first air guide plate 21 and the second air guide plate 22 and the front and rear sides of the corresponding packaging shell 301 do not change. Therefore, after the sea breeze flows into the gaps on the left and right sides of the packaging shell 301, the flow speed of the sea breeze decreases, reducing the amount of heat removed from the packaging shell 301, thereby reducing the heat dissipation effect on the lithium battery module 4 and ensuring that the lithium battery module 4 is within an appropriate temperature range.

[0041] When the temperature sensor in the fixed inner shell 3 detects that the temperature of the lithium battery module 4 is higher than the appropriate range, the electromagnetic module 53 is turned off, so that the first air guide plate 21 and the corresponding second air guide plate 22 move toward each other under the action of the tension spring between the two until the first air guide plate 21 and the second air guide plate 22 are reset.

[0042] Example 3

[0043] This embodiment discloses a solid-state lithium battery with a heat dissipation structure for ship propulsion. Based on Example 2, it also has the function of dissipating heat from the first wind deflector 21 and the second wind deflector 22, thereby improving the efficiency of heat dissipation of the lithium battery.

[0044] Please compare Figures 4-10 , an array of central air guide plates 61 are slidably connected in the fixed inner shell 3, and the number of central air guide plates 61 is six. The central air guide plates 61 are located between the adjacent first air guide plates 21 and the adjacent second air guide plates 22, and the central air guide plates 61 separate the air outlets 303 corresponding to the first air guide plates 21 and the adjacent second air guide plates 22. The left and right sides of the central air guide plates 61 respectively form a gas flow channel with the adjacent first air guide plates 21 and the adjacent second air guide plates 22, providing a flow space for the sea breeze, that is, the sea breeze can enter the heat dissipation cavity 302 through the air outlet 303, and the central air guide plates 61 divert the sea breeze entering from the air outlet 303, dividing the sea breeze into two parts on the left and right, and making the sea breeze flow along the left and right sides of the central air guide plates 61. In the process of the sea breeze flowing along the gas flow channel, the sea breeze takes away the heat on the first air guide plates 21 and the second air guide plates 22, thereby achieving a cooling operation on the first air guide plates 21 and the second air guide plates 22.

[0045] Example 4

[0046] When the sea breeze passes through the first and second wind guide plates 21 and 22, it will cause slight corrosion on the surfaces of the first and second wind guide plates 21 and 22, resulting in the generation of corrosion impurities on the surfaces of both. This will reduce the heat dissipation efficiency of both. Based on this problem, the following solution is proposed: This embodiment discloses a solid-state lithium battery for ship propulsion. Based on Example 3, it also has the function of cleaning impurities on the surface of the first wind guide plate 21 and the corresponding second wind guide plate 22, thereby ensuring the heat conduction efficiency of the first wind guide plate 21 and the second wind guide plate 22.

[0047] Please compare Figure 4-Figure 7 、 Figure 9 and Figure 10The fixed inner shell 3 is equipped with two symmetrically distributed driving push rods 71. The driving push rods 71 ​​are existing electric push rods. The power output ends of the two driving push rods 71 ​​are fixedly connected to a driving frame 72. The driving frame 72 is composed of several round rods and several square frames, and the square frames and round rods are staggered. The driving frame 72 is slidingly connected to the fixed inner shell 3. The middle air guide plate 61 is fixedly connected with a connecting rod 73. The driving frame 72 is used to push the connecting rod 73 to move in the front and rear directions, and the connecting rod 73 is located in the square frame of the driving frame 72. Five grooves distributed in a linear array are provided on the middle air guide plate 61 for receiving the heat dissipation protrusions 31 on the corresponding first air guide plate 21 and the corresponding second air guide plate 22, so that the middle air guide plate 61 can fit with the corresponding first air guide plate 21 and the corresponding second air guide plate 22.

[0048] Please compare Figure 6-Figure 8 Several friction protrusions 81 are provided on both sides of the middle air guide plate 61. The friction protrusions 81 are used to increase the roughness of the surface of the middle air guide plate 61 to facilitate cleaning of the corresponding first air guide plate 21 and the corresponding second air guide plate 22.

[0049] The working principle of a solid-state lithium battery for ship propulsion in this embodiment is as follows: During the navigation of the ship, impurities on the surfaces of the first wind guide plate 21 and the second wind guide plate 22 are cleaned regularly. When both need to be cleaned, the driving push rod 71 is turned on to make the power output end of the driving push rod 71 move back and forth. The power output end of the driving push rod 71 drives the driving frame 72 to move back and forth. The driving frame 72 pushes all the connecting rods 73 thereon to move. The connecting rods 73 drive the adjacent middle wind guide plate 61 to move. The middle wind guide plate 61 drives the friction protrusions 81 thereon to move synchronously.

[0050] When the driving push rod 71 is turned on, all electromagnetic modules 53 are turned on synchronously, and all electromagnetic modules 53 generate magnetic repulsion, so that the corresponding two magnetic blocks 52 move backwards, and the corresponding two magnetic blocks 52 respectively drive the corresponding first air guide plate 21 and the second air guide plate 22 to move backwards (the tension spring between the two is stretched), until the first air guide plate 21 and the second air guide plate 22 contact the adjacent middle air guide plate 61, so that the magnetic repulsion of the electromagnetic module 53 remains constant.

[0051] When the first air guide plate 21 and the second air guide plate 22 are in contact with the adjacent middle air guide plate 61, as the middle air guide plate 61 moves back and forth, the first air guide plate 21 and the second air guide plate 22 move relative to the adjacent middle air guide plate 61, and the friction protrusion 81 moves relative to the adjacent first air guide plate 21 and the second air guide plate 22, thereby achieving the operation of scraping off impurities on the first air guide plate 21 and the second air guide plate 22.

[0052] After a single cleaning operation is completed, all the middle air guide plates 61 are reset by driving the push rod 71, and all the electromagnetic modules 53 are turned off, and all the first air guide plates 21 and the second air guide plates 22 are reset under the action of the tension springs thereon.

[0053] Example 5

[0054] This embodiment discloses a solid-state lithium battery with a heat dissipation structure for ship propulsion. On the basis of Example 4, it also has the function of further dissipating heat to the first wind guide plate 21 and the corresponding second wind guide plate 22, thereby ensuring the heat conduction efficiency of the first wind guide plate 21 and the second wind guide plate 22.

[0055] Please compare Figure 9 and Figure 10 , the upper side of the middle air guide plate 61 is fixedly connected with a fixed block 91, and the fixed block 91 is fixedly connected with a magnetic block 2 92. An elastic member is provided between the magnetic block 2 92 and the fixed inner shell 3, and the elastic member is a spring. Six pairs of electromagnetic modules 2 93 distributed in an array are fixedly connected in the fixed inner shell 3. The magnetic block 2 92 is located between adjacent pairs of electromagnetic modules 2 93. When the electromagnetic module 2 93 is energized, the electromagnetic module 2 93 generates a magnetic repulsion force and drives the corresponding magnetic block 2 92 to move. The newly introduced parts in this section are all located on the front side of the fixed inner shell 3. The newly introduced parts in this section are also provided on the rear side of the fixed inner shell 3 in the present invention, thereby ensuring the smooth movement of the middle air guide plate 61.

[0056] The working principle of a solid-state lithium battery with a heat dissipation structure for ship propulsion in this embodiment is as follows: During the operation of the temperature sensor in the fixed inner shell 3, when it is detected that the temperature of the lithium battery module 4 in a certain area increases, the temperature of the first air guide plate 21 and the second air guide plate 22 in the area increases synchronously. Figure 10 For example, the temperature of the second air guide plate 22 rises, and the electromagnetic module 2 93 on the right is turned on at this time. The electromagnetic module 2 93 generates a magnetic repulsion force. The electromagnetic module 2 93 drives the magnetic block 2 92 to move to the left through the magnetic repulsion force. The elastic part of the magnetic block 2 92 is stretched and stored, and the magnetic block 2 92 drives the middle air guide plate 61 to move to the left through the fixed block 91. At this time, the distance between the middle air guide plate 61 and the second air guide plate 22 increases, increasing the amount of sea breeze entering between the middle air guide plate 61 and the second air guide plate 22, thereby increasing the effect of cooling the second air guide plate 22. When the temperature of the second air guide plate 22 returns to the normal range, the electromagnetic module 2 93 is turned off, and the magnetic block 2 92 is reset under the action of the elastic part thereon, and drives the middle air guide plate 61 to reset. If the temperature of the first air guide plate 21 rises, the electromagnetic module 2 93 on the left is started to increase the distance between the first air guide plate 21 and the corresponding middle air guide plate 61, thereby cooling the first air guide plate 21.
