Description

Technical Field

[0001] This invention relates to the field of lithium battery heat dissipation technology, specifically to a solid-state lithium battery with a heat dissipation structure for marine propulsion. Background Technology

[0002] Solid-state batteries generate significant internal heat during high-power charging and discharging. If this heat cannot be dissipated in time, it may lead to uneven temperature distribution inside the battery, resulting in decreased interfacial stability between the solid electrolyte and electrode materials, accelerated lithium dendrite growth, and even thermal runaway. Meanwhile, marine propulsion systems often need to cope with continuous high-load conditions, so solid-state lithium batteries require specially designed heat dissipation structures for marine propulsion applications.

[0003] A search revealed Chinese patent CN120674733B, which includes a mounting housing with a sealing cover fixedly connected to it, and a fixed inner housing fixedly connected to it. The sealing cover and the fixed inner housing together form a sealed cavity. The fixed inner housing has several encapsulation shells and a heat dissipation cavity. A lithium battery module is installed within each encapsulation shell on the fixed inner housing. The terminals of the lithium battery module are located within the sealed cavity between the fixed inner housing and the sealing cover. This invention, by placing the lithium battery module within the encapsulation shells, isolates the lithium battery module from sea breeze, thereby reducing its probability of sea breeze corrosion. Simultaneously, sealing the lithium battery module within the sealed cavity between the sealing cover and the fixed inner housing prevents sea breeze from blowing onto the terminals of the lithium battery module, thus preventing corrosion of the terminals.

[0004] However, the above-mentioned solutions improve the heat dissipation of lithium batteries by increasing the heat dissipation area, but do not add other cooling mechanisms. Essentially, this is passive heat dissipation, and the peak heat dissipation efficiency largely depends on the ambient temperature. In summer or tropical regions with high ambient temperatures, the heat dissipation efficiency improved by increasing the flow channel area alone is still insufficient to meet the long-term high-load working requirements of lithium batteries. On the other hand, the above-mentioned solutions provide sealed protection for lithium batteries through the encapsulation shell. Although this achieves anti-salt spray effect, sea air is directly poured into the flow channel without treatment. Due to the complexity of the flow channel and the fact that impurities are shaken off by the fins and paddles, a large amount of impurities will accumulate at the bottom of the flow channel after long-term operation. Additional shutdown maintenance is required to open the shell for cleaning. Otherwise, it will become a dead zone for hygiene and corrosion. Especially at the corners at the bottom of the flow channel, the accumulated damp salt impurities may form a local corrosive environment, continuously eroding the shell or structure it contacts, resulting in limited anti-salt spray effect of the solution.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please see Figures 1 to 9 This invention provides a technical solution: a solid-state lithium battery with a heat dissipation structure for marine power, including a base plate 1, a filter assembly for anti-salt spray effect, and a heat dissipation assembly for flow channel purging. Side plates 11 are fixedly connected to both sides of the long side of the upper surface of the base plate 1, and multiple wind baffles 12 are fixedly connected to both sides of the short side of the upper surface of the base plate 1. The top ends of the side plates 11 and the wind baffles 12 are fixedly connected to the same top plate 13. An air inlet 14 is provided on one side of the base plate 1, and a dust collection box 15 is fixedly connected to one end of the air inlet 14. An exhaust end 16 is provided on the side of the base plate 1 away from the air inlet 14, and a louver 17 is provided inside the exhaust end 16. The filter assembly includes an air intake pipe 3 for achieving air intake effect. The air intake pipe 3 is fixedly connected to the inside of the air intake end 14 and a self-driven air pump is installed inside the air intake pipe 3. The heat dissipation component includes a positioning shaft 5 driven by a built-in motor, which is connected through and rotatably limited to the center of the bottom end of the top plate 13.

[0021] In this design, the base plate 1 and top plate 13 serve as the external frame structure of the battery module, isolating the electromagnetic module from the external environment. The wind deflector 12 isolates the inlet and outlet of the flow channel, thereby ensuring efficient airflow between multiple flow channels and effectively improving the heat dissipation efficiency of the design. The air inlet 14 and exhaust 16 restrict the airflow direction of the design, ensuring that the sea breeze enters from the air inlet 14, first passes through the filter assembly to remove impurities such as salt mist mixed inside, and then the filtered sea breeze completes the heat dissipation operation through the flow channel before being discharged from the exhaust 16. The dust collection box 15 is used to collect dust in the sea breeze filtration operation, collecting salt mist impurities in the sea breeze. The louvers 17 are used to prevent outside air from entering the interior of the base plate 1 in reverse, further ensuring the working environment of the battery module.

[0022] Example 2: The upper surface of the base plate 1 is provided with a plurality of lithium batteries 2. Each of the plurality of lithium batteries 2 is fitted with an encapsulation shell 21 on its outer contour. Each encapsulation shell 21 is fixedly connected to two ends of a current guide 22. Each current guide 22 has a plurality of semiconductor cooling chips 23 passing through its interior. The cold end of each semiconductor cooling chip 23 is in contact with the encapsulation shell 21, and the hot end of each semiconductor cooling chip 23 passes through the current guide 22 and is exposed to the outside.

[0023] The area between the bottom plate 1 and the top plate 13 is divided by multiple lithium batteries 2 to form a diamond-shaped mesh flow channel, and multiple wind deflectors 12 are adapted to the inlet and outlet of the flow channel to achieve isolation.

[0024] The heat dissipation effect of this solution includes two effects: heat dissipation by the filtered sea breeze and heat dissipation by the contact between the thermoelectric cooler 23 and the battery module. The lithium battery 2 is in close contact with the package shell 21 to conduct the heat generated during high-load operation to the surface of the package shell 21. The contact surface between the package shell 21 and the flow guide 22 is provided with a cavity, so that the heat on the surface of the package shell 21 accumulates in the cavity and comes into contact with the cold end of the thermoelectric cooler 23. The cold end of the thermoelectric cooler 23 achieves rapid cooling to meet the heat dissipation requirements of the lithium battery 2. At the same time, the flow of the filtered sea breeze in the flow channel continuously removes the heat dissipated by the hot end of the thermoelectric cooler 23, further ensuring the heat dissipation efficiency of the solution.

[0025] It should be noted that, due to the diamond array distribution among the battery modules, i.e., the flow channel has a diamond mesh structure, and the intersections and dispersion points of multiple flow channels are designed with large angles, the large angle design at the corners can effectively guide the flow direction of the gas when the filtered sea air passes through the flow channel. This further avoids the formation of turbulence at the corners, reduces the residence time of the gas in the flow channel, thereby effectively improving the heat dissipation efficiency of the solution and further avoiding the probability of impurities in the gas accumulating at the corners, thus effectively improving the heat dissipation quality of the solution.

[0026] Example 3: One end of the air intake pipe 3 is fixedly connected to a filter pipe 31, and the other end of the filter pipe 31 extends out of the air intake end 14 and communicates with the dust collection box 15. A flange ring 32 is nested at the bottom end of the filter pipe 31, and a centrifugal tube 33 is nested at the bottom end of the flange ring 32. An outlet end 34 is fixedly connected at the bottom end of the centrifugal tube 33. The bottom end of the outlet end 34 is fixedly connected to the end of the air intake pipe 3 away from the filter pipe 31. A sealing pin 35 is slidably connected inside the bottom end of the outlet end 34, and a buoyancy ball 36 is fixedly connected to the top end of the sealing pin 35.

[0027] The filter assembly also includes a sealing ring 4 fixedly connected inside the filter tube 31. The sealing ring 4 partially seals the connection between the filter tube 31 and the flange ring 32. A guide ring 41 is fixedly connected to the inner contour of the sealing ring 4. A guide vane 42 is fixedly connected to the outer contour of the middle section of the guide ring 41. A partition 43 is fixedly connected to the top of one side of the sealing ring 4 to separate the filter tube 31. A fixed shaft 44 is provided at the center of the sealing ring 4. The top of the fixed shaft 44 is fixedly connected to the inner wall of the filter tube 31. The bottom of the fixed shaft 44 extends out of the bottom of the guide ring 41 and is fixedly connected to a fixed plate 45. The fixed plate 45 is adapted to the size of the outlet end 34.

[0028] The air intake pipe 3 is connected to multiple air intakes formed by the flow channel being separated by the baffle plate 12.

[0029] First, the air intake is achieved by the air pump in the air intake pipe 3. The sea breeze enters through the filter pipe 31, is filtered, and then enters the flow channel. At the same time, the filtered impurities are discharged into the dust collection box 15 through the other end of the air intake pipe 3 to complete the collection.

[0030] After the sea breeze enters the filter tube 31 under the suction of the air pump, it is first blocked by the baffle 43 and cannot enter the intake pipe 3. At this time, the sealing ring 4 achieves a semi-closed connection between the filter tube 31 and the flange ring 32. That is, the end of the filter tube 31 near the intake pipe 3 is blocked from the flange ring 32, while the end of the filter tube 31 away from the intake pipe 3 is connected to the flange ring 32. At this time, the sea breeze enters the flange ring 32 through this gap and is retained in the centrifuge tube 33. When the sea breeze enters the centrifuge tube 33, it first passes through the guide vane 42. Under the cutting and turbulence action of the guide vane 42, the sea breeze forms a vortex between the centrifuge tube 33 and the guide ring 41. The vortex speed is controlled by the power of the air pump. The higher the power of the air pump, the higher the vortex speed, and the lower the power of the air pump, the lower the turbine speed.

[0031] Furthermore, the eddies generated by the sea breeze produce centrifugal force, the magnitude of which is synchronized with the eddy speed. The salt mist within the sea breeze is essentially composed of small droplets of salty liquid suspended in the air and tiny, dried salt crystals, whose density is far greater than that of air. When the salty air is forcibly drawn into the centrifuge tube 33 at high speed along the tangential direction of the guide vane 42, a high-speed rotating eddy is formed. Within this eddy, a centrifugal acceleration far greater than gravitational acceleration is generated. In this centrifugal force field, the outward force on the denser salt droplets and particles is far greater than that on the less dense air molecules. Therefore, the solid and liquid particles in the sea breeze are violently thrown against the inner wall of the centrifuge tube 33. The salt particles thrown against the inner wall lose kinetic energy and slide down the wall under gravity, thus achieving complete separation from the airflow.

[0032] That is, the sea breeze is subjected to centrifugal separation within the flange ring 32. The solid and liquid particles inside are located on the outside and slide down along the inner wall of the centrifuge tube 33. The airflow is located in the center of the inside. The clean air that has lost most of the particles forms an upward inner vortex in the central area, and then is discharged upward through the inside of the guide ring 41 to the inside of the filter tube 31. At this time, the clean air enters the inside of the air inlet pipe 3 from the filter tube 31 under the suction effect of the air pump, and then enters the flow channel to complete the heat dissipation operation.

[0033] On the other hand, the solid and liquid particles that slide down the centrifuge tube 33 fall into the outlet end 34 and accumulate at the bottom of the outlet end 34 to form a mixture. When the mixture accumulates to a large extent, it comes into contact with the buoyancy ball 36. Since the proportion of water molecules in the sea breeze is much greater than the proportion of salt particles, the mixture can be regarded as a high-salt water solution. The buoyancy ball 36 is essentially an air bladder. The buoyancy it experiences in the high-salt water solution is much greater than its own weight. Therefore, as the mixture gradually accumulates, it comes into contact with and is lifted by the buoyancy ball 36 and rises synchronously.

[0034] Furthermore, the buoyancy ball 36 drives the sealing pin 35 to rise synchronously. The top of the sealing pin 35 rises and releases the blockage on the bottom of the outlet end 34. At this time, the mixed liquid flows into the air inlet pipe 3 from the bottom of the outlet end 34 and is blown into the dust collection box 15 by the air pump to achieve collection.

[0035] The reduction of the mixed liquid in the outlet end 34 will cause the buoyancy ball 36 and the sealing pin 35 to descend. At this time, the top of the sealing pin 35 will block the outlet end 34 again, thereby dynamically controlling the discharge operation by the amount of mixed liquid and realizing the self-cleaning effect of the filter component in the scheme.

[0036] Example 4: A main gear 51 is fixedly connected to the outer contour of the positioning shaft 5. Both ends of the main gear 51 are meshed with secondary gears 52. A drive shaft 53 is fixedly connected to the center of each of the two secondary gears 52. The two drive shafts 53 are also connected through and rotatably to the bottom of the top plate 13. A chain 54 is connected to the outer contour of each of the two drive shafts 53. A drive shaft 55 is connected to the end of each chain 54 away from the drive shaft 53. The two drive shafts 55 are also connected through and rotatably to the bottom of the top plate 13. A fixing ring 56 is fixedly connected to the top of each of the two drive shafts 55. A chain 57 is connected to the outer contour of each fixing ring 56.

[0037] The heat dissipation assembly also includes transmission rings 6 connected to the inner contours of both ends of the chain 57. Each transmission ring 6 has a reciprocating screw 61 fixedly connected to its bottom end. Each reciprocating screw 61 has a fixing sleeve 62 screwed onto its outer contour. The reciprocating screw 61 is rotatably connected to the bottom end of the top plate 13. The bottom ends of multiple fixing sleeves 62 are fixedly connected to the same flow channel plate 63. The flow channel plate 63 has the same shape as the flow channel. Multiple sealing plates 64 are fixedly connected to both ends of the upper surface of the flow channel plate 63. The multiple sealing plates 64 are adapted to the inlet and outlet dimensions formed by the flow channel being separated by the baffle plate 12.

[0038] While the air pump is working, the positioning shaft 5 works synchronously and drives the main gear 51 to rotate. The main gear 51 further drives the secondary gear 52 to rotate. The secondary gear 52 drives the transmission shaft 55 to rotate synchronously via the transmission shaft 53 and the chain 54. The transmission shaft 55 further drives the transmission ring 6 to rotate synchronously via the fixed ring 56 and the chain 57. Since the transmission ring 6 is fixedly connected to the reciprocating screw 61, the rotation direction of the four transmission rings 6 and the reciprocating screw 61 is consistent at this time.

[0039] Furthermore, the fixed sleeve 62 is screwed to the outside of the reciprocating screw 61 and tends to rotate synchronously with the reciprocating screw 61. However, its bottom end is fixedly connected to the flow channel plate 63, which is embedded in the flow channel. Due to the contact restriction of the flow channel, the flow channel plate 63 cannot rotate, causing all the fixed sleeves 62 to be unable to rotate. Then, under the effect of the screw connection of the reciprocating screw 61, the rotation of the reciprocating screw 61 will drive the fixed sleeve 62 to extend downward. The fixed sleeve 62 further drives the flow channel plate 63 and the sealing plate 64 to descend synchronously. The descent of the flow channel plate 63 gradually compresses the flow channel space, and the descent of the sealing plate 64 gradually blocks the inlet and outlet of the flow channel formed by the baffle plate 12.

[0040] Furthermore, due to the double thread setting of the reciprocating screw 61, when the fixed sleeve 62 extends downward along the reciprocating screw 61 to the limit position, it automatically retracts upward and drives the flow channel plate 63 and the sealing plate 64 to rise. That is, the positioning shaft 5 drives the reciprocating screw 61 to rotate in one direction, thereby realizing the reciprocating lifting and lowering motion effect of the flow channel plate 63 and the sealing plate 64.

[0041] Since the filter components cannot completely remove water molecules and salt particles from the sea breeze, a small amount of impurities still remain in the filtered sea breeze. When the sea breeze passes through the flow channel, there is still a risk that the impurities will adhere to the inner wall of the flow channel, forming condensation and corroding the guide end 22 and the thermoelectric cooler 23. Therefore, the sealing plate 64 is pressed down to achieve the effect of periodically scraping and cleaning the outer wall of the guide end 22 and the thermoelectric cooler 23, scraping off the condensation adhering to the surface of the guide end 22 and the thermoelectric cooler 23 and dripping it to the bottom of the flow channel.

[0042] On the other hand, the downward pressure of the sealing plate 64 blocks the inlet and outlet of the flow channel. When the sealing plate 64 descends to its limit position, the space of the flow channel reaches its minimum range under the compression of the flow channel plate 63, and the inlet size of the flow channel is at its minimum value. At this time, according to Bernoulli's principle, the pressure on the gas when it enters the flow channel through the air inlet pipe 3 is reduced, so its flow velocity into the flow channel increases significantly. At this time, the filtered sea air flows at high speed in the flow channel. Through the high-speed flow of the gas, the condensate dripping at the bottom of the flow channel is blown and discharged from the flow channel, completing the self-cleaning effect of the flow channel. The blown-out condensate is discharged through the exhaust end 16. Since the louver 17 is only set in the upper part of the exhaust end 16, the louver 17 will not have an interception effect on the condensate at the bottom.

[0043] Furthermore, the dwell height of the flow channel plate 63 and the sealing plate 64 can be controlled by the start / stop positioning shaft 5 to adjust the size of the flow channel inlet / outlet and internal space. By changing the size of the flow channel space, the gas flow rate can be controlled. The faster the gas flows in the flow channel, the higher its heat dissipation efficiency. In combination with the power adjustment of the air pump and the current working state of the lithium battery 2, a dynamic balance of the heat dissipation power of the solution can be achieved.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
