Description

Technical Field

[0001] The present invention belongs to the technical field of energy storage for new energy vehicle battery modules, and particularly relates to a distributed liquid-cooled energy storage cabinet. Background Art

[0002] A distributed liquid-cooled energy storage cabinet is an energy storage device that integrates and manages multiple energy storage units in a distributed manner and uses liquid-cooling technology to dissipate heat and control the temperature of the energy storage system. It can achieve energy storage and release. The liquid-cooled energy storage cabinet is mainly used for charging new energy vehicle battery modules. The battery modules are placed in the energy storage cabinet for charging, and the temperature reduction and monitoring of the battery modules are realized through liquid-cooling technology and temperature detection.

[0003] Existing distributed energy storage cabinets usually use non-immersion liquid cooling to cool the internal battery modules. Non-immersion liquid cooling; in a non-immersion liquid-cooling system, the liquid-cooling pipes usually do not directly contact the battery cells but are arranged as close to the batteries as possible. These pipes may be laid along the inner wall of the energy storage cabinet. When the battery generates heat, the heat is conducted to the nearby liquid-cooling pipes through media such as air, and then the coolant takes away the heat.

[0004] During the use of the existing energy storage cabinets, if the temperature of the pipes is much lower than the ambient temperature, then when the water vapor in the air meets the low-temperature pipe surface, the water vapor in the air will reach the saturation state due to the cold, and thus condense into small water droplets on the pipe surface, resulting in condensation of the pipes inside the cabinet (for example, in an environment with slightly higher humidity, if the pipe surface temperature is lower than the ambient temperature by more than 5°C, condensation is likely to occur). Since the battery cells are close to the pipes, the small water droplets are likely to penetrate into the battery interior and damage the battery. Summary of the Invention

[0005] The purpose of the present invention is to provide a distributed liquid-cooled energy storage cabinet in view of the deficiencies of the prior art to solve the technical problems in the prior art.

[0006] The object of the present invention can be achieved by the following technical solutions: A distributed liquid-cooled energy storage cabinet, which includes a cabinet body. A converter control unit, a central control unit, and a liquid-cooled unit are respectively installed inside the cabinet body. A battery pack is installed inside the cabinet body. The liquid-cooled unit dissipates heat from the battery pack through a heat dissipation pipe group. A battery seat is slidably installed inside the cabinet body, and the battery pack is placed on the battery seat. A cylinder is installed on the inner wall of the cabinet body, the output end of the cylinder is connected to the battery seat, and the battery seat is connected to an adjustment component; The liquid-cooled unit includes an outlet pipe and an inlet pipe. The heat dissipation pipe group includes a liquid distribution head and heat dissipation pipes. Liquid distribution heads are respectively installed on the outlet pipe and the inlet pipe. The liquid distribution heads are connected to the heat dissipation pipes through hoses, and the battery pack is close to the heat dissipation pipes; The adjustment component includes a limit block and a connecting rod. A slider is slidably installed on the inner wall of the cabinet body. The slider is connected to the limit block through the connecting rod, and the limit block is connected to the battery seat through a rope; When the cylinder pushes the battery seat to move, the battery seat drives the limit block to move through the rope, so that the limit block drives the slider to squeeze the hose through the connecting rod.

[0007] As a further optimization or improvement of this solution, a pressing head is installed on the slider, and the slider squeezes the hose through the pressing head.

[0008] As a further optimization or improvement of this solution, a chute is opened on the inner wall of the cabinet body. The slider is slidably matched with the chute through a sliding head, and the sliding head is connected to the inner wall of the chute through a first spring.

[0009] As a further optimization or improvement of this solution, a positioning baffle is installed on the inner wall of the cabinet body, and the outer wall of the hose fits against the positioning baffle; A pulley is installed on the inner wall of the cabinet body, and the rope passes through the pulley and is respectively connected to the limit block and the battery seat.

[0010] As a further optimization or improvement of this solution, a liquid absorption component is installed on the slider. The liquid absorption component includes a liquid absorption sleeve plate, and the liquid absorption sleeve plate is connected to the inner wall of the cabinet body through a second spring.

[0011] As a further optimization or improvement of this solution, a driven inclined block is installed on the back of the liquid absorption sleeve plate, a push plate is installed on the slider, the push plate abuts against the driven inclined block through a driving inclined block thereon, folding plates are installed on both sides of the liquid absorption sleeve plate, and a water absorption sponge is installed inside the liquid absorption sleeve plate.

[0012] As a further optimization or improvement of this solution, a slide bar is installed inside the cabinet body, and the slide bar is slidably matched with the battery seat.

[0013] The beneficial effects of the present invention: (1) In the present invention, a cylinder is used to push the battery holder, causing the battery holder and the battery pack to slide along the slide bar, so that the battery pack moves away from the heat dissipation pipe, preventing water droplets on the surface of the heat dissipation pipe from dripping onto the battery pack. During the movement of the battery holder, the battery holder pulls the limit block to move through a rope, and the limit block pushes the slider to slide along the chute through a connecting rod, so that the slider squeezes the hose through a pressing head, slowing down the flow rate of the liquid inside the heat dissipation pipe. The temperature of the heat dissipation pipe relatively increases, making the temperature of the heat dissipation pipe approach the ambient temperature and inhibiting the formation of water droplets. Specifically, when the slider slides along the chute, the slider drives the push plate thereon to move synchronously. Under the cooperation of the active inclined block and the driven inclined block, the push plate drives the liquid absorption sleeve plate to move closer to the heat dissipation pipe through the active inclined block, so that the water absorption sponge inside the liquid absorption sleeve plate wraps the heat dissipation pipe and absorbs the liquid beads on the heat dissipation pipe.

[0014] (2) In the present invention, a cylinder is used to push the battery holder and the battery pack to move synchronously, causing the battery pack to move away from the heat dissipation pipe. During this process, the battery holder pulls the limit block to move through a rope, and the limit block pushes the slider to slide along the chute through a connecting rod, so that the slider squeezes the hose through a pressing head, slowing down the flow rate of the liquid inside the heat dissipation pipe. The temperature of the heat dissipation pipe relatively increases, making the temperature of the heat dissipation pipe approach the ambient temperature and inhibiting the formation of water droplets. At the same time, the battery pack is pushed, causing the battery pack to slide along the guide bar on the battery holder, making the battery pack closer to the heat dissipation pipe, ensuring the heat dissipation effect of the battery pack while inhibiting the generation of water droplets on the surface of the heat dissipation pipe.

Specific implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0028] See Figures 1 - 7, A distributed liquid-cooled energy storage cabinet, which includes a cabinet body 1. Inside the cabinet body 1, a converter control unit 2, a central control unit 3, and a liquid-cooling unit 4 are respectively installed. A battery pack 5 is installed inside the cabinet body 1. The liquid-cooling unit 4 dissipates heat from the battery pack 5 through a heat dissipation pipe group 6. A battery seat 7 is slidably installed inside the cabinet body 1, and the battery pack 5 is placed on the battery seat 7. A cylinder 10 is installed on the inner wall of the cabinet body 1, and the output end of the cylinder 10 is connected to the battery seat 7. The battery seat 7 is connected to an adjustment component 8; the liquid-cooling unit 4 includes an outlet pipe 401 and an inlet pipe 402. The heat dissipation pipe group 6 includes a liquid distribution head 601 and heat dissipation pipes 602. Liquid distribution heads 601 are respectively installed on the outlet pipe 401 and the inlet pipe 402. The liquid distribution head 601 is connected to the heat dissipation pipes 602 through a hose 603, and the battery pack 5 is close to the heat dissipation pipes 602; the adjustment component 8 includes a limit block 801 and a connecting rod 802. A slider 803 is slidably installed on the inner wall of the cabinet body 1. The slider 803 is connected to the limit block 801 through the connecting rod 802. The limit block 801 is connected to the battery seat 7 through a rope 809; when the cylinder 10 pushes the battery seat 7 to move, the battery seat 7 drives the limit block 801 to move through the rope 809, so that the limit block 801 drives the slider 803 to squeeze the hose 603 through the connecting rod 802.

[0029] Specifically, a slide bar 11 is installed inside the cabinet body 1, and the slide bar 11 is slidably matched with the battery seat 7.

[0030] Specifically, a pressing head 804 is installed on the slider 803, and the slider 803 squeezes the hose 603 through the pressing head 804.

[0031] It should be noted that during the installation process of the battery pack 5, first place the battery pack 5 on the battery seat 7. The battery pack 5 is respectively connected to the converter control unit 2 and the central control unit 3 through lines, and the lines need to reserve a fixed length to meet the condition that the battery pack 5 can be displaced. A guide groove is opened at the bottom of the battery pack 5, and a guide bar is installed on the battery seat 7. The guide groove on the battery pack 5 is slidably matched with the guide bar on the battery seat 7.

[0032] In the initial state, see Figure 7 , the battery pack 5 is close to the heat dissipation pipes 602, and at the same time, the battery pack 5 is in contact with the limit block 801. At this time, a gap is reserved between the battery pack 5 and the heat dissipation pipes 602 to prevent the heat dissipation pipes 602 from being too cold to the battery pack 5 due to direct contact; in the initial state, the liquid absorption sleeve plate 901 is separated from the heat dissipation pipes 602.

[0033] The present invention uses a non-immersive liquid-cooling method to cool the battery pack 5, that is, the heat dissipation of the battery pack 5 is realized by the battery pack 5 being close to the heat dissipation pipes 602. The specific method is as follows; The liquid-cooling unit 4 outputs the liquid-cooling liquid through the outlet pipe 401 and returns it through the inlet pipe 402. At the same time, the liquid-cooling unit 4 controls the circulation of the liquid-cooling liquid. During this process, seeFigure 5 The liquid cooling liquid inside the liquid outlet pipe 401 is introduced into the liquid distribution head 601. The liquid distribution head 601 disperses the liquid cooling liquid to each heat dissipation pipe 602 through the hose 603. Then, the liquid inside the heat dissipation pipe 602 converges to the liquid distribution head 601 and is discharged from the liquid inlet pipe 402. Through this cycle, the purpose of cooling the battery pack 5 is achieved.

[0034] When the present invention is actually in use, if the temperature of the heat dissipation pipe 602 is much lower than the ambient temperature, when water vapor in the air encounters the surface of the low-temperature heat dissipation pipe 602, it is easy to condense into small water droplets. Since the battery pack 5 of this application is cooled by being close to the heat dissipation pipe 602, therefore, the water droplets are likely to drip on the battery pack 5, causing short-circuit damage to the battery pack 5.

[0035] Based on this, the present invention uses the cylinder 10 to push the battery seat 7, so that the battery seat 7 and the battery pack 5 slide along the slide bar 11, making the battery pack 5 move away from the heat dissipation pipe 602, and preventing the water droplets on the surface of the heat dissipation pipe 602 from dripping on the battery pack 5; During the movement of the battery seat 7, the battery seat 7 pulls the limit block 801 to move through the rope 809. The limit block 801 pushes the slider 803 to slide along the chute 805 through the connecting rod 802, so that the slider 803 squeezes the hose 603 through the pressing head 804, slowing down the liquid flow rate inside the heat dissipation pipe 602. The temperature of the heat dissipation pipe 602 relatively increases, making the temperature of the heat dissipation pipe 602 approach the ambient temperature and inhibiting the formation of water droplets; When the slider 803 slides along the chute 805, the slider 803 drives the push plate 904 thereon to move synchronously. Under the cooperation of the active inclined block 905 and the driven inclined block 903, the push plate 904 drives the liquid absorption sleeve plate 901 to move closer to the heat dissipation pipe 602 through the active inclined block 905, so that the water absorption sponge 907 inside the liquid absorption sleeve plate 901 wraps the heat dissipation pipe 602 and absorbs the liquid beads on the heat dissipation pipe 602.

[0036] Finally, the cylinder 10 drives the battery seat 7 and the battery pack 5 to reset. During the reset process of the battery seat 7, the rope 809 is relaxed, and under the action of the first spring 806, the slider 803 and the liquid absorption sleeve plate 901 are reset.

[0037] Another usage mode of the present invention is as follows. First, the cylinder 10 is used to push the battery holder 7 and the battery pack 5 to move synchronously, so that the battery pack 5 moves away from the heat dissipation pipeline 602. During this process, the battery holder 7 pulls the limit block 801 to move through the rope 809, and the limit block 801 pushes the slider 803 to slide along the chute 805 through the connecting rod 802, so that the slider 803 squeezes the hose 603 through the pressing head 804, slowing down the flow rate of the liquid inside the heat dissipation pipeline 602. The temperature of the heat dissipation pipeline 602 relatively increases, making the temperature of the heat dissipation pipeline 602 approach the ambient temperature and inhibiting the formation of water droplets. At the same time, the battery pack 5 is pushed, so that the battery pack 5 slides along the guide bar on the battery holder 7, making the battery pack 5 approach the heat dissipation pipeline 602 and making the battery pack 5 closer to the heat dissipation pipeline 602. While this method inhibits the generation of water droplets on the surface of the heat dissipation pipeline 602, it ensures the heat dissipation effect of the battery pack 5.

[0038] It should be noted that since the liquid outlet pipe 401, the liquid inlet pipe 402 and the liquid distribution head 601 do not directly participate in the heat dissipation operation, heat insulation sleeves can be sleeved on the liquid outlet pipe 401, the liquid inlet pipe 402 and the liquid distribution head 601, thereby improving the transportation efficiency of the refrigerant and avoiding the generation of water droplets on the liquid outlet pipe 401, the liquid inlet pipe 402 and the liquid distribution head 601. Since the heat dissipation pipeline 602 directly participates in the heat dissipation function, generally, the heat dissipation pipeline 602 does not need to be sleeved with a heat insulation sleeve to ensure the heat conduction efficiency of the heat dissipation pipeline 602.

[0039] See Figure 7 , a chute 805 is provided on the inner wall of the cabinet body 1, and the slider 803 is slidably matched with the chute 805 through a sliding head 811. The sliding head 811 is connected to the inner wall of the chute 805 through a first spring 806.

[0040] Specifically, a positioning baffle 810 is installed on the inner wall of the cabinet body 1, and the outer wall of the hose 603 is attached to the positioning baffle 810. A pulley 808 is installed on the inner wall of the cabinet body 1, and the rope 809 passes through the pulley 808 and is respectively connected to the limit block 801 and the battery holder 7.

[0041] It should be noted that after the dew removal of the present invention is completed, the cylinder 10 drives the battery holder 7 and the battery pack 5 to reset. During the reset process of the battery holder 7, the rope 809 is relaxed, and under the action of the first spring 806, the slider 803 and the liquid suction sleeve plate 901 are reset.

[0042] See Figures 7 - 10 , a liquid suction assembly 9 is installed on the slider 803. The liquid suction assembly 9 includes a liquid suction sleeve plate 901, and the liquid suction sleeve plate 901 is connected to the inner wall of the cabinet body 1 through a second spring 902.

[0043] Specifically, a driven inclined block 903 is installed on the back of the liquid absorption sleeve plate 901, a push plate 904 is installed on the slider 803, the push plate 904 abuts against the driven inclined block 903 through the active inclined block 905 thereon, folding plates 906 are installed on both sides of the liquid absorption sleeve plate 901, and a water absorption sponge 907 is installed inside the liquid absorption sleeve plate 901.

[0044] It should be noted that when the slider 803 slides along the chute 805, the slider 803 drives the push plate 904 thereon to move synchronously. Under the cooperation of the active inclined block 905 and the driven inclined block 903, the push plate 904 drives the liquid absorption sleeve plate 901 to move closer to the heat dissipation pipe 602 through the active inclined block 905, so that the water absorption sponge 907 inside the liquid absorption sleeve plate 901 wraps the heat dissipation pipe 602 and absorbs the liquid beads on the heat dissipation pipe 602, preventing the water droplets on the surface of the heat dissipation pipe 602 from dripping onto the battery pack 5.

[0045] The working principle of the present invention: The present invention uses a non-immersive liquid cooling method to cool the battery pack 5, that is, the battery pack 5 is cooled by being close to the heat dissipation pipe 602. The specific method is as follows; The liquid cooling unit 4 outputs the liquid cooling liquid through the liquid outlet pipe 401 and returns it through the liquid inlet pipe 402. At the same time, the liquid cooling unit 4 controls the circulation of the liquid cooling liquid. During this process, refer to Figure 5 , the liquid cooling liquid inside the liquid outlet pipe 401 is introduced into the liquid distribution head 601, and the liquid distribution head 601 disperses the liquid cooling liquid to each heat dissipation pipe 602 through the hose 603. Then, the liquid inside the heat dissipation pipe 602 converges to the liquid distribution head 601 and is discharged from the liquid inlet pipe 402, circulating in this way to achieve the purpose of cooling the battery pack 5.

[0046] When the present invention is actually used, if the temperature of the heat dissipation pipe 602 is much lower than the ambient temperature, when the water vapor in the air encounters the surface of the low-temperature heat dissipation pipe 602, it is easy to condense into small water droplets. Since the battery pack 5 of this application is cooled by being close to the heat dissipation pipe 602, therefore, the water droplets are easy to drip on the battery pack 5, causing the battery pack 5 to be short-circuited and damaged.

[0047] Based on this, the present invention uses the cylinder 10 to push the battery holder 7, so that the battery holder 7 and the battery pack 5 slide along the slide bar 11, so that the battery pack 5 is away from the heat dissipation pipe 602, preventing the water droplets on the surface of the heat dissipation pipe 602 from dripping onto the battery pack 5; During the movement of the battery holder 7, the battery holder 7 pulls the limit block 801 to move through the rope 809, and the limit block 801 pushes the slider 803 to slide along the chute 805 through the connecting rod 802, so that the slider 803 squeezes the hose 603 through the pressing head 804, slowing down the liquid flow rate inside the heat dissipation pipe 602, and the temperature of the heat dissipation pipe 602 relatively increases, making the temperature of the heat dissipation pipe 602 approach the ambient temperature and inhibiting the formation of water droplets; When the slider 803 slides along the chute 805, the slider 803 drives the push plate 904 thereon to move synchronously. Under the cooperation of the active inclined block 905 and the driven inclined block 903, the push plate 904 drives the liquid suction sleeve plate 901 to move closer to the heat dissipation pipe 602 through the active inclined block 905, so that the water-absorbing sponge 907 inside the liquid suction sleeve plate 901 wraps the heat dissipation pipe 602 and absorbs the liquid beads on the heat dissipation pipe 602. Finally, the air cylinder 10 drives the battery holder 7 and the battery pack 5 to reset. During the reset process of the battery holder 7, the rope 809 is relaxed, and the slider 803 and the liquid suction sleeve plate 901 are reset under the action of the first spring 806.

[0048] Another usage mode of the present invention is as follows. First, the air cylinder 10 is used to push the battery holder 7 and the battery pack 5 to move synchronously, so that the battery pack 5 moves away from the heat dissipation pipe 602. During this process, the battery holder 7 pulls the limit block 801 to move through the rope 809, and the limit block 801 pushes the slider 803 to slide along the chute 805 through the connecting rod 802, so that the slider 803 squeezes the hose 603 through the pressing head 804, slowing down the liquid flow rate inside the heat dissipation pipe 602. The temperature of the heat dissipation pipe 602 relatively increases, making the temperature of the heat dissipation pipe 602 approach the ambient temperature and inhibiting the formation of water beads. At the same time, the battery pack 5 is pushed, so that the battery pack 5 slides along the guide bar on the battery holder 7, making the battery pack 5 closer to the heat dissipation pipe 602 and ensuring the heat dissipation effect of the battery pack 5 while inhibiting the generation of water beads on the surface of the heat dissipation pipe 602.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
