Description

Technical Field

[0001] The present invention relates to the field of lithium batteries, and in particular to an intelligent lithium battery for communication backup power. Background Art

[0002] Smart lithium battery technology has been widely used in industry. In industrial production, smart lithium batteries can be used as a flexible on-board power supply to provide uninterrupted power supply, thereby ensuring production efficiency. However, in the south, the temperature is high all year round, and batteries often overheat. If the battery cannot be cooled in time, it is easy to cause safety hazards.

[0003] CN117895144A discloses a heat dissipation structure and a heat dissipation method of a lithium battery pack. The heat dissipation structure of the lithium battery pack uses a control mechanism to adjust the speed at which movable plates located on both sides of the lithium battery pack move toward the air outlet, and can adjust the flow pattern of gas in the outer shell, so that the cooling effect on both sides of the lithium battery pack is as consistent as possible.

[0004] However, when the air is taken in, the "air inlet" is likely to bring external dust into the "chamber", thereby covering the surfaces of the "lithium battery pack" and the "control mechanism" with a layer of dust, which may cause the heat in the "lithium battery pack" to be dissipated to the outside at a slower rate. The "first electromagnet" and the "second electromagnet" being covered with dust will more or less reduce their magnetism, slowing down the movement speed of the "movable plate", thereby weakening the cooling effect on the "lithium battery pack". If the "lithium battery pack" is at a higher temperature and cannot be cooled quickly, there will be certain safety hazards. For this reason, the present invention provides an intelligent lithium battery for communication backup power. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention is simple to operate and has obvious effects. The battery pack is cooled by the combination of the air cooling device and the liquid cooling device, thereby achieving a rapid cooling effect.

[0020] The heat absorbing tube moves up and down on the side of the battery pack, and the side of the battery pack is cooled by the fluid in the heat absorbing tube. Due to the up and down movement of the heat absorbing tube, the fluid in the heat absorbing tube is always in a flowing state. The pressure brought to the internal fluid by the lifting and lowering of the two container parts is used to make the fluid flow back and forth in the two container parts, which can improve the heat absorption effect of the heat absorbing tube on the battery pack; at the same time, the air volume generated by the fan not only cools the battery pack, but also takes away part of the heat of the fluid, so that the fluid can better cool the battery pack;

[0021] The cleaning brush moves up and down with the heat absorbing tube, which can keep the surface of the battery pack clean and help dissipate the heat inside the battery pack, so as to cool the battery pack;

[0022] The air inlet opens or closes automatically when the cooling system is turned on or off. It does not require manual operation, which is more convenient and can prevent dust from entering when not in use.

[0023] The push plate pushes the fluid on its upper side into the drive box to make the drive box descend, and the control component drives the air inlet plate to move up to open the air inlet. The unidirectional rotation of the limiting plate makes it easy to squeeze the fluid in the container part 2 into the drive box when the push plate moves up and down, so that the drive box is always in a downward state during the process of cooling the battery pack to ensure the opening of the air inlet. After the cooling is completed, the fluid in the drive box can flow into the container part 2 through the flow hole 1, so that the air inlet plate gradually moves down to close the air inlet.

[0024] The container part 2 faces the battery pack and can also absorb the heat generated by the battery pack. The fluid flows between the container part 2 and the drive box, and heat is dissipated during the fluid flow, thereby absorbing more heat generated by the battery pack and accelerating the cooling of the battery pack.

DETAILED DESCRIPTION

[0042] Embodiment 1:

[0043] See also Figure 1-Figure 14 The present invention provides a technical solution: Figure 1-Figure 3 As shown, a smart lithium battery for communication backup power includes a housing 1, a battery pack 2 located in the housing 1, and a heat dissipation system 3 arranged between the housing 1 and the battery pack 2, and the heat dissipation system 3 simultaneously performs air cooling and liquid cooling on the battery pack 2; the heat dissipation system 3 includes a liquid cooling device 31 and an air cooling device 32 that can be raised and lowered, the liquid cooling device 31 is distributed on both sides of the battery pack 2 in the length direction, the air cooling device 32 is arranged on the adjacent side of the liquid cooling device 31, and the liquid cooling device 31 is relatively fitted with the battery pack 2;

[0044] The air cooling device 32 includes an air cooling structure 321 and a lifting structure 322. The lifting structure 322 is meshed and connected with the air cooling structure 321, and moves up and down as the air cooling structure 321 is started. The lifting structure 322 is fixedly connected with the liquid cooling device 31. As the lifting structure 322 is lifted and lowered, the liquid cooling device 31 absorbs heat from the side of the battery pack 2.

[0045] An air inlet control structure 4 that can be raised and lowered is installed on the side wall of the shell 1 close to the air cooling device 32. The air inlet control structure 4 is fixedly connected to the lifting structure 322. When the lifting structure 322 is raised and lowered, the air inlet control structure 4 is driven to rise to open the air inlet 11 opened on the side wall of the shell 1, thereby supplying air to the air cooling structure 321.

[0046] like Figure 2-Figure 5 As shown, the liquid cooling device 31 includes a pair of liquid cooling components 311 located on both sides of the length direction of the battery pack 2, and the liquid cooling components 311 include a pair of liquid cooling boxes 312, a pair of retractable container parts 313 and a heat absorbing part 314. The liquid cooling boxes 312 are fixedly connected to the bottom of the shell 1, and the opposite sides of the pair of liquid cooling boxes 312 are open. The container parts 313 are filled with cooling fluid, such as water or coolant, and one of the container parts 313 is arranged on the lower side of one of the liquid cooling boxes 312. The first container 313 is provided with a liquid infusion tube 3131 at the lower side of the first container 313, and the liquid infusion tube 3131 extends out of the liquid cooling box 312 and communicates with the lower side of the heat absorbing member 314. Another first container 313 is arranged on the upper side of the other liquid cooling box 312 and is fixedly connected to the top of the liquid cooling box 312. The first container 313 is provided with a liquid infusion tube 3132 at the upper side of the first container 313, and the liquid infusion tube 3132 extends out of the liquid cooling box 312 and communicates with the lower side of the heat absorbing member 314. 4, so that the inside of a pair of container parts 1 313 and the heat absorbing part 314 are connected, so that the cooling fluid flows inside, the infusion tube 1 3131 and the infusion tube 2 3132 are respectively close to the two sides of the heat absorbing part 314, and the side of the heat absorbing part 314 away from the liquid cooling box 312 is attached to the side of the battery pack 2, and the heat absorbing part 314 is fixedly connected to the lifting structure 322, and the heat absorbing part 314 can follow the lifting structure 322 to rise and fall, thereby being able to drive the pair of container parts 1 313 to stretch or shrink Since the heat absorbing member 314 is connected to the lower side of one container member 313 and the upper side of the other container member 313 respectively through the infusion tube 1 3131 and the infusion tube 2 3132, the stretching or contraction direction between a pair of container members 1 313 is opposite, forcing the cooling fluid to circulate back and forth in the container member 1 313, the heat absorbing member 314, and the container member 1 313 to absorb heat and cool the side of the battery pack 2; the material of the container member 1 313 is flexible, so it can be stretched or contracted.

[0047] The heat absorption component 314 includes a plurality of heat absorption tubes 331, a plurality of connecting tubes 332 and a lifting plate 333. The plurality of heat absorption tubes 331 are arranged at intervals, preferably three heat absorption tubes 331. One side of the heat absorption tube 331 is in contact with the battery pack 2, and the other side of the heat absorption tube 331 located in the middle is fixedly connected to the lifting plate 333. The plurality of connecting tubes 332 are connected between adjacent heat absorption tubes 331. The heat absorption tube 331 near the bottom of the shell 1 is fixedly connected to the end of the infusion tube 1 3131 near the lifting structure 322, and the end is further extended and fixedly connected to the lifting structure 322. When the heat absorption tube 331 is extended, it bypasses the rotation range of the air-cooling structure 321 to prevent collision with the air-cooling structure 321 during lifting. The heat absorption tube 331 near the top of the shell 1 is fixedly connected to the infusion tube 2 3132, and the connection is located at the end of the heat absorption tube 331 away from the lifting structure 322. A fixing plate 3133 extends from the opposite side of a pair of container parts 313 toward the middle of a pair of liquid cooling boxes 312. The fixing plate 3133 is fixedly connected to the lifting plate 333, and the fixing plate 3133 is driven to rise or fall by the lifting plate 333. The two fixing plates 3133 are respectively fixedly connected to the upper side and the lower side of the pair of container parts 313.

[0048] A cleaning brush 334 is fixedly connected to the lower side of the heat absorption tube 331 . The cleaning brush 334 is in contact with the battery pack 2 . When the cleaning brush 334 moves along with the heat absorption tube 331 , it cleans the surface of the battery pack 2 to prevent the accumulation of impurities such as dust.

[0049] like Figure 4 and Figure 6 As shown, the air cooling structure 321 includes a motor 51 and a pair of fans 52. The motor 51 is a dual-axis motor. The motor 51 is remotely controlled by a mobile terminal. The driving shaft of the motor 51 is transmission-connected to the central shaft of the fan 52. The motor 51 and the fan 52 are both supported and mounted on the shell 1. The air volume generated by the rotation of the fan 52 is transported to the surroundings of the battery pack 2 to cool the battery pack 2. The air inlet 11 and the inlet control structure 4 are both a pair, and the number and position correspond to the fan 52.

[0050] The lifting structure 322 includes a main wheel 61, a pair of secondary wheels 62, a pair of meshing members 63 and a meshing plate 64. The pair of secondary wheels 62 are meshed and connected to both sides of the main wheel 61. The pair of meshing members 63 are correspondingly fixedly connected to the middle of the pair of secondary wheels 62. The rotation of the main wheel 61 drives the pair of secondary wheels 62 and the meshing members 63 to rotate in the opposite direction. The meshing plate 64 is located in the middle of the pair of meshing members 63 and always maintains a meshing connection state with only one of the meshing members 63, that is, one of the meshing members 63 drives When the engaging plate 64 descends, the other engaging member 63 drives the engaging plate 64 to rise (this is a conventional technical means and will not be elaborated on), and vice versa, so that the engaging plate 64 is always in a cyclic state of lifting and lowering movement; the main wheel 61 is fixedly connected to a rotating shaft in the middle of a side close to the battery pack 2, and the rotating shaft is transmission-connected to a vertical reversing rod 611, and the reversing rod 611 is transmission-connected to any drive shaft of the motor 51 to obtain power, and the reversing rod 611, the rotating shaft and the main wheel 61 are driven to rotate through the drive shaft.

[0051] like Figure 4 and Figure 8 As shown, the lower end of the engaging plate 64 is fixedly connected to a lifting rod 641, and both ends of the lifting rod 641 are fixedly connected to the extended ends of the heat absorption tube 331, thereby driving the heat absorption tube 331 on both sides of the battery pack 2 to move up and down; the upper side of the lifting rod 641 is fixedly connected to the bottom end of a pushing member 642, and the top end of the pushing member 642 is fixedly connected to the air intake control structure 4.

[0052] like Figure 8-Figure 13 As shown, the air inlet control structure 4 includes an air inlet plate 41, a driving component 42 and a control component 43. The air inlet plate 41 is slidably connected to the inner wall of the housing 1, and the lower end is rotatably connected to one end of the control component 43. The other end of the control component 43 is fixedly connected to the lower side of the driving component 42. The driving component 42 descends to drive the other end of the control component 43 to descend, and one end of the control component 43 rises to drive the air inlet plate 41 to rise to open the air inlet 11 (see Fig.13 );

[0053] The driving assembly 42 includes a liquid tank 421, a second container part 422 and a driving box 423. The liquid tank 421 is fixedly connected to the middle of the inner wall of the shell 1, and the side close to the fan 52 is open. The second container part 422 is slidably connected to the liquid tank 421. The second container part 422 is a flexible material container that can be extended and retracted, which is convenient for extension and retraction in the liquid tank 421. The second container part 422 is filled with fluid, preferably water. The middle of the second container part 422 is fixedly connected to a push plate 441, which extends to the outside of the liquid tank 421 and is fixedly connected to the top of the push member 642. The part of the push plate 441 located inside the second container part 422 is provided with a plurality of flow holes, and some of the flow holes are rotatably connected to a flow limiting plate 442 that can rotate toward the upper side through a torsion spring (see Fig.11), so that only one-way drainage from the inside to the outside is possible; the drive box 423 is slidably connected to the side wall of the shell 1 and is located on the upper side of the air inlet plate 41, the bottom of the drive box 423 is higher than the top of the container part 2 422, and the upper end of the container part 2 422 is fixedly extended with a fluid pipe 1 424 and a fluid pipe 2 425 and respectively connected to the top of the drive box 423 and the lower part of the side wall, so that the container part 2 422, the drive box 423, the fluid pipe 1 424 and the fluid pipe 2 425 are connected to the inside of the drive box 423, and the upper part of the container part 2 422 is compressed by moving the push rod 642 upward, and the fluid in the container part 2 422 flows to the drive box 4 through the fluid pipe 1 424 23. The driving box 423 is filled with water and moves downward. The inner diameter of the fluid tube 1 424 is much larger than the inner diameter of the fluid tube 2 425. When moving upward, more water will choose to be discharged from the fluid tube 1 424, and a small amount of water will be discharged from the fluid tube 2 425. When the push rod 642 moves downward, the fluid in the driving box 423 flows back to the container part 2 422 through the fluid tube 2 425, and the lower part of the container part 2 422 shrinks, and the fluid on the lower side of the push plate 441 rushes outward to open the flow limiting plate 442 and flows to the upper side of the push plate 441. When the container part 2 422 rises again, the flow limiting plate 442 closes the one-way flow hole and drives the fluid into the driving box 423.

[0054] The control assembly 43 includes a control rod 1 431 and a control rod 2 432. One end of the control rod 1 431 is fixedly connected to the lower side of the drive box 423, and the other end is rotatably connected to one end of the control rod 2 432. The control rod 1 431 is slidably connected to the side wall of the shell 1, and the other end of the control rod 2 432 is rotatably connected to the lower end of the air inlet plate 41. The middle part of the control rod 2 432 is rotatably connected to the side wall of the shell 1 (the rotation point is shown in FIG. Fig.12 ), the driving box 423 moves downward to drive the control rod 1 431 to move downward, so that the control rod 2 432 pushes the air inlet plate 41 to move upward around the rotation point to open the air inlet 11 (see Fig.13 ); When the pusher 642 drives the container part 422 to move downward, the fluid in the drive box 423 flows back to the container part 422 through the fluid pipe 425. When the container part 422 is at the starting point of being compressed upward again, the weight of the fluid in the drive box 423 is still greater than the weight of the air inlet plate 41, and the air inlet 11 is still in an open state.

[0055] A U-shaped limit opening 111 with an opening facing downward is formed on the side wall of the housing 1 along the upper side of the middle periphery of the air inlet 11. A limit plate 112 is fixedly connected to the limit opening 111 near the battery pack 2. A sliding plate 411 is fixedly connected to the top of the air inlet plate 41. The sliding plate 411 extends into the limit opening 111 and exceeds the limit plate 112.

[0056] The shell 1 has an abutment plate 114 protruding along the lower side of the outer periphery of the air inlet plate 41 for placing the air inlet plate 41, so that the air inlet plate 41 can only move vertically up and down between the abutment plate 114 and the limit opening 111 to ensure the stability of the movement of the air inlet plate 41 and to ensure that the air inlet 11 can be accurately opened. When the lower side of the air inlet plate 41 abuts against the abutment plate 114, the air inlet 11 is in a closed state; when the air inlet plate 41 moves upward and the sliding plate 411 abuts against the limit opening 111, the air inlet 11 is in an open state; the air inlet 11 is closed when it is misaligned with the air inlet channel on the surface of the air inlet plate 41, and is open when it is connected.

[0057] like Fig.14 As shown, a plurality of air outlets are provided on the side wall of the shell 1 away from the driving box 423 , and the air outlets are rotatably connected to a rotating plate 113 via a torsion spring, and the rotating plate 113 rotates toward the outside of the shell 1 to form a one-way air outlet.

[0058] Working principle: When the temperature of the battery pack 2 is too high, the operator starts the motor 51 through the mobile terminal, and the motor 51 drives the fan 52 to rotate, and also drives the reversing rod 611 to rotate, and the reversing rod 611 drives the main wheel 61, a pair of secondary wheels 62 and the meshing member 63 to rotate, and the meshing plate 64, the lifting rod 641 and the pushing member 642 are driven by the meshing member 63 to move up and down in a reciprocating manner;

[0059] When the lifting rod 641 moves upward, it drives the heat absorbing tube 331, the connecting tube 332 and the lifting plate 333 to move upward, and the lifting plate 333 drives a pair of fixing plates 3133 to move upward, one of the fixing plates 3133 pushes the container part 1 313 located on the upper side of the liquid cooling box 312 to compress, and the other fixing plate 3133 drives the container part 1 313 located on the lower side of the liquid cooling box 312 to stretch, thereby forcing the fluid in the container part 1 313 located on the upper side of the liquid cooling box 312 to flow into the liquid cooling box 312 through the infusion pipe 2 313. The liquid flows into the heat absorbing tube 331 and the connecting tube 332, and finally flows into the container part 1 313 located at the lower side of the liquid cooling box 312 through the lowermost heat absorbing tube 331 and the infusion tube 1 3131, so as to realize the flow of the fluid. When the heat absorbing tube 331 moves upward, the temperature of the battery pack 2 is taken away with the flow of the fluid. On the contrary, when the lifting plate 333 drives a pair of fixed plates 3133 to move downward, the fluid flows in the opposite direction, and the reciprocating cycle is used to drive the heat of the battery pack 2 and cool the battery pack 2.

[0060] At the same time, when the pushing member 642 moves upward, it drives the pushing plate 441 to move upward, thereby forcing the fluid in the container part 2 422 located on the upper side of the pushing plate 441 to enter the driving box 423 through the fluid pipe 1 424. When the pushing plate 441 moves upward, although part of the fluid flows to the lower side of the pushing plate 441 through the non-unidirectional flow hole, most of the remaining fluid can enter the driving box 423, and use the gravity of the fluid to force the driving box 423 to drive the control rod 1 431 to move downward, thereby driving the control rod 2 432 to rotate, and the air inlet plate 41 is pushed upward by the lever principle of the rotating point until the sliding plate 411 is completely embedded in the limit opening 111 to open the air inlet 11; conversely, when the pushing member 642 drives the pushing plate 441 to descend, the fluid in the driving box 423 flows to the container part 2 422 again through the fluid pipe 2 425. In the device 2 422, part of the fluid flows to the lower side of the push plate 441 through the non-unidirectional flow hole. As the push plate 441 continues to move downward, the flow limiting plate 442 is flushed open by the fluid on the lower side, and the fluid on the lower side of the push plate 441 flows to the upper side of the push plate 441 again through the unidirectional flow hole at the flow limiting plate 442. Since the inner diameter of the fluid tube 2 425 is much smaller than that of the fluid tube 1 424, when the push plate 441 descends, the fluid in the drive box 423 still keeps the drive box 423 in a downward state, that is, the air inlet 11 is in an open state. When the push plate 441 moves downward to the limit, the push member 642 drives the push plate 441 to move upward again, thereby squeezing the fluid on the upper side of the push plate 441 in the container device 2 422 into the drive box 423, so that the air inlet 11 is always in an open state when the push plate 411 moves up and down.

[0061] When the air inlet 11 is opened, the rotating fan 52 generates air to blow toward the side of the battery pack 2, cooling the battery pack 2 and the fluid in the container 313, thereby achieving simultaneous air cooling and liquid cooling of the battery pack 2. At the same time, the fluid can also be cooled by air cooling, so the heat absorption tube 331 has a better cooling effect on the battery pack 2, thereby maximizing the cooling of the battery pack 2 and eliminating the safety hazard caused by overheating of the battery pack 2; the cleaning brush 334 moves up and down with the heat absorption tube 331, avoiding dust and other impurities from being retained on the surface of the battery pack 2 after the air passes through the surface of the battery pack 2, ensuring the cleanliness of the surface of the battery pack 2 and being able to fully dissipate the internal heat for easy cooling; after the air flows to the side of the battery pack 2 away from the fan 52, it finally flows out from the air outlet;

[0062] After the temperature of the battery pack 2 drops to a safe range, the operator turns off the motor 51 through the mobile terminal, and the lifting rod 641, the heat absorption tube 331, the pushing member 642 and the pushing plate 441 gradually stop moving. At this time, the fluid in the drive box 423 will gradually flow into the container part 2 422 through the fluid tube 2 425, and part of it will flow to the lower side of the pushing plate 441 through the one-way flow hole. As the weight of the drive box 423 decreases, the air inlet plate 41 will gradually move downward, and the drive box 423 will be pushed upward in the opposite direction by the control rod 2 432 and the control rod 1 431 until the air inlet plate 41 closes the air inlet 11. At this time, the pushing plate 441 is submerged in the fluid in the container part 2 422.

[0063] Embodiment 2:

[0064] On the basis of Example 1, Fig.14 As shown, the side of the battery pack 2 away from the air cooling structure 321 is set as the air outlet side, and the air outlet side is also provided with a lifting structure 322, a reversing rod 611 and a lifting rod 641, so as to drive the heat absorption tube 331 to move from both sides of the heat absorption tube 331 at the same time to ensure the stability of the movement; the lifting structures 322 on both sides of the battery pack 2 are connected through the main rod transmission arranged at the bottom of the shell 1.

[0065] Embodiment 3:

[0066] On the basis of Example 2, Figure 15-16 As shown, an air guide 315 is fixedly connected to the side of one of the liquid cooling boxes 312 close to the fan 52. The air guide 315 is located on the side of the liquid cooling box 312 close to the battery pack 2 and is flush with the open side of the liquid cooling box 312. It is used to guide the flow of air to prevent the air from flowing to the open side of the other liquid cooling box 312, thereby reducing the loss of air.
