Description

Technical Field

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

[0002] A distributed liquid-cooled energy storage cabinet integrates and manages multiple energy storage units in a distributed manner, using liquid cooling technology to dissipate heat and control the temperature of the energy storage system. It enables both energy storage and release. Liquid-cooled energy storage cabinets are primarily used for charging battery modules in new energy vehicles. Battery modules are placed in the cabinet for charging, and liquid cooling technology and temperature detection are used to cool and monitor the battery modules.

[0003] Existing distributed energy storage cabinets typically use non-immersive liquid cooling to cool the battery modules within. In non-immersive liquid cooling systems, the cooling pipes typically avoid direct contact with the battery cells, but are placed as close to them as possible. These pipes may be laid along the inner walls of the energy storage cabinet. When the batteries generate heat, the heat is transferred through a medium such as air to the nearby cooling pipes, where the coolant then removes the heat.

[0004] In conventional energy storage cabinets, if the pipe temperature is significantly lower than the ambient temperature during use, water vapor in the air will reach saturation when it encounters the cold pipe surface, condensing into small water droplets on the pipe surface. This can cause condensation in the pipes inside the cabinet (for example, in a slightly humid environment, condensation is likely to occur if the pipe surface temperature is more than 5°C lower than the ambient temperature). Because the battery cells are close to the pipes, these small water droplets can easily penetrate into the batteries and damage them. Summary of the Invention

[0005] The purpose of the present invention is to provide a distributed liquid-cooled energy storage cabinet to address the shortcomings of the existing technology and solve the technical problems in the existing technology.

[0006] The objectives of the present invention can be achieved through the following technical solutions: a distributed liquid-cooled energy storage cabinet, which includes a cabinet body, wherein a current conversion control unit, a central control unit and a liquid cooling unit are respectively installed in the cabinet body, a battery pack is installed in the cabinet body, and the liquid cooling unit dissipates heat to the battery pack through a heat dissipation pipe group. A battery seat is slidably installed in 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, and the output end of the cylinder is connected to the battery seat, and the battery seat is connected to an adjustment component; the liquid cooling unit includes a liquid outlet pipe and a liquid inlet pipe, and the heat dissipation pipe group includes a liquid distributor and a heat dissipation pipe. Liquid distributors are respectively installed on the liquid outlet pipe and the liquid inlet pipe, and the liquid distributor is connected to the heat dissipation pipe through a hose, and the battery pack is close to the heat dissipation pipe; 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 a 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 pressure head is installed on the slider, and the slider squeezes the hose through the pressure head.

[0008] As a further optimization or improvement of this solution, a sliding groove is provided on the inner wall of the cabinet, and the slider is slidably engaged with the sliding groove via a slider, and the slider is connected to the inner wall of the sliding groove via a spring.

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

[0010] As a further optimization or improvement of this solution, a liquid suction component is installed on the slider, and the liquid suction component includes a liquid suction sleeve, and the liquid suction sleeve is connected to the inner wall of the cabinet through spring 2.

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

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

[0013] Beneficial effects of the present invention:

[0014] (1) The present invention pushes the battery holder through the cylinder, so that the battery holder and the battery pack slide along the slide bar, so that the battery pack is away from the heat dissipation pipe, and water droplets on the surface of the heat dissipation pipe are prevented from dripping onto the battery pack; during the movement of the battery holder, the battery holder pulls the limit block to move through the rope, and the limit block pushes the slider to slide along the slide groove through the connecting rod, so that the slider squeezes the hose through the pressure head, slowing down the flow rate of the liquid inside the heat dissipation pipe, and the temperature of the heat dissipation pipe is relatively increased, so that the temperature of the heat dissipation pipe approaches the ambient temperature, and the formation of water droplets is suppressed;

[0015] Specifically, when the slider slides along the slide groove, the slider drives the push plate on it to move synchronously. With the cooperation of the active inclined block and the driven inclined block, the push plate drives the liquid absorption sleeve to move close to the heat dissipation pipe through the active inclined block, so that the water-absorbing sponge inside the liquid absorption sleeve covers the heat dissipation pipe and absorbs the liquid droplets on the heat dissipation pipe.

[0016] (2) The present invention uses a cylinder to push the battery holder and the battery pack to move synchronously, so that the battery pack is away from the heat dissipation pipe. During this process, the battery holder pulls the limit block to move through the rope, and the limit block pushes the slider to slide along the slide groove through the connecting rod, so that the slider squeezes the hose through the pressure head, slowing down the flow rate of the liquid inside the heat dissipation pipe, and the temperature of the heat dissipation pipe is relatively increased, so that the temperature of the heat dissipation pipe approaches the ambient temperature, and the formation of water droplets is suppressed; at the same time, the battery pack is pushed to slide along the guide bar on the battery holder, so that the battery pack is close to the heat dissipation pipe, and the battery pack is closer to the heat dissipation pipe. This method suppresses the formation of water droplets on the surface of the heat dissipation pipe while ensuring the heat dissipation effect of the battery pack. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] See also Figure 1-Figure 7A distributed liquid-cooled energy storage cabinet includes a cabinet 1, in which a converter control unit 2, a central control unit 3, and a liquid cooling unit 4 are installed respectively. A battery pack 5 is installed in the cabinet 1, and the liquid cooling unit 4 dissipates heat to the battery pack 5 through a heat dissipation pipe group 6. A battery holder 7 is slidably installed in the cabinet 1, and the battery pack 5 is placed on the battery holder 7. A cylinder 10 is installed on the inner wall of the cabinet 1, and the output end of the cylinder 10 is connected to the battery holder 7, and the battery holder 7 is connected to the adjustment component 8; the liquid cooling unit 4 includes a liquid outlet pipe 401 and a liquid inlet pipe 402, and the heat dissipation pipe group 6 includes a liquid distributor 601 and a heat dissipation pipe 602. The liquid outlet pipe 401 and the liquid inlet The liquid dispensing heads 601 are respectively installed on the tubes 402, and the liquid dispensing heads 601 are connected to the heat dissipation pipe 602 through the hose 603, and the battery pack 5 is close to the heat dissipation pipe 602; the adjustment component 8 includes a limit block 801 and a connecting rod 802, and a slider 803 is slidably installed on the inner wall of the cabinet 1, and the slider 803 is connected to the limit block 801 through the connecting rod 802, and the limit block 801 is connected to the battery holder 7 through the rope 809; when the cylinder 10 pushes the battery holder 7 to move, the battery holder 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.

[0036] Specifically, a slide bar 11 is installed inside the cabinet 1 , and the slide bar 11 is slidably matched with the battery holder 7 .

[0037] Specifically, a pressure head 804 is installed on the slider 803 , and the slider 803 squeezes the hose 603 through the pressure head 804 .

[0038] It should be noted that during the installation of the battery pack 5, the battery pack 5 is first placed on the battery holder 7. The battery pack 5 is connected to the converter control unit 2 and the central control unit 3 via wiring. The wiring requires a fixed length to ensure that the battery pack 5 can be moved. A guide groove is defined at the bottom of the battery pack 5, and a guide bar is installed on the battery holder 7. The guide groove on the battery pack 5 slides with the guide bar on the battery holder 7.

[0039] In the initial state, see Figure 7 , the battery pack 5 is close to the heat dissipation pipe 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 pipe 602 to avoid direct contact between the battery pack 5 and the heat dissipation pipe 602, which causes the heat dissipation pipe 602 to overcool the battery pack 5; in the initial state, the liquid absorption sleeve 901 is separated from the heat dissipation pipe 602.

[0040] The present invention uses a non-immersion liquid cooling method to cool the battery pack 5, that is, the heat dissipation of the battery pack 5 is achieved by placing the battery pack 5 close to the heat dissipation pipe 602. The specific method is as follows;

[0041] 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. Figure 5 The liquid cooling liquid inside the liquid outlet pipe 401 is passed into the liquid separation head 601, and the liquid separation 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 separation head 601 and is discharged from the liquid inlet pipe 402, thereby circulating to achieve the purpose of heat dissipation of the battery pack 5.

[0042] During actual use of the present invention, if the temperature of the heat dissipation pipe 602 is much lower than the ambient temperature, water vapor in the air will easily condense into small water droplets when encountering the low-temperature surface of the heat dissipation pipe 602. Since the battery pack 5 of the present application is cooled by being close to the heat dissipation pipe 602, water droplets can easily drip onto the battery pack 5, causing short circuit damage to the battery pack 5.

[0043] Based on this, the present invention pushes the battery holder 7 through the cylinder 10, 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, and prevents water droplets on the surface of the heat dissipation pipe 602 from dripping onto the battery pack 5;

[0044] During the movement of the battery holder 7, the battery holder 7 pulls the limit block 801 to move via the rope 809. The limit block 801 pushes the slider 803 to slide along the slide groove 805 via the connecting rod 802. The slider 803 squeezes the hose 603 via the pressure head 804, slowing down the flow rate of the liquid inside the heat dissipation pipe 602. The temperature of the heat dissipation pipe 602 rises relatively, making the temperature of the heat dissipation pipe 602 approach the ambient temperature, thereby preventing the formation of water droplets.

[0045] When the slider 803 slides along the slide groove 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 901 to move close to the heat dissipation pipe 602 through the active inclined block 905, so that the water-absorbing sponge 907 inside the liquid absorption sleeve 901 covers the heat dissipation pipe 602 and absorbs the liquid droplets on the heat dissipation pipe 602.

[0046] Finally, 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 the slider 803 and the liquid-absorbing sleeve 901 are reset under the action of the spring 1 806.

[0047] Another way of using the present invention is to first push the battery holder 7 and the battery pack 5 to move synchronously through the cylinder 10, so that the battery pack 5 is 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 slide groove 805 through the connecting rod 802, so that the slider 803 squeezes the hose 603 through the pressure head 804, slowing down the liquid flow rate inside the heat dissipation pipe 602, and the temperature of the heat dissipation pipe 602 is relatively increased, so that the temperature of the heat dissipation pipe 602 approaches the ambient temperature, and the formation of water droplets is suppressed; at the same time, the battery pack 5 is pushed to slide along the guide bar on the battery holder 7, so that the battery pack 5 is close to the heat dissipation pipe 602, so that the battery pack 5 is closer to the heat dissipation pipe 602. This method suppresses the formation of water droplets on the surface of the heat dissipation pipe 602 while ensuring the heat dissipation effect of the battery pack 5.

[0048] It should be noted that, since the liquid outlet pipe 401, the liquid inlet pipe 402 and the liquid separation head 601 are not directly involved in the heat dissipation operation, the liquid outlet pipe 401, the liquid inlet pipe 402 and the liquid separation head 601 can be covered with a thermal insulation sleeve, thereby improving the refrigerant delivery efficiency and avoiding the formation of water droplets on the liquid outlet pipe 401, the liquid inlet pipe 402 and the liquid separation head 601; since the heat dissipation pipe 602 is directly involved in the heat dissipation effect, the heat dissipation pipe 602 generally does not need to be covered with a thermal insulation sleeve to ensure the thermal conductivity efficiency of the heat dissipation pipe 602.

[0049] See also Figure 7 The inner wall of the cabinet 1 is provided with a slide groove 805 , and the slider 803 slides in cooperation with the slide groove 805 through a slider 811 , and the slider 811 is connected to the inner wall of the slide groove 805 through a spring 806 .

[0050] Specifically, a positioning baffle 810 is installed on the inner wall of the cabinet 1, and the outer wall of the hose 603 is in contact with the positioning baffle 810; a pulley 808 is installed on the inner wall of the cabinet 1, and a rope 809 passes through the pulley 808 and is connected to the limit block 801 and the battery holder 7 respectively.

[0051] 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 of the battery holder 7, the rope 809 is loosened, and the slider 803 and the liquid-absorbing sleeve 901 are reset under the action of the spring 1 806.

[0052] See also Figure 7-10 The liquid absorption component 9 is installed on the slider 803. The liquid absorption component 9 includes a liquid absorption cover plate 901. The liquid absorption cover plate 901 is connected to the inner wall of the cabinet 1 through a spring 902.

[0053] Specifically, a driven inclined block 903 is installed on the back of the liquid-absorbing sleeve 901, a push plate 904 is installed on the slider 803, and 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-absorbing sleeve 901, and a water-absorbing sponge 907 is installed inside the liquid-absorbing sleeve 901.

[0054] It should be noted that when the slider 803 slides along the slide groove 805, the slider 803 drives the push plate 904 thereon to move synchronously. With the cooperation of the active inclined block 905 and the driven inclined block 903, the push plate 904 drives the liquid absorption sleeve 901 to move close to the heat dissipation pipe 602 through the active inclined block 905, so that the water-absorbing sponge 907 inside the liquid absorption sleeve 901 covers the heat dissipation pipe 602 and absorbs the liquid droplets on the heat dissipation pipe 602, thereby preventing the water droplets on the surface of the heat dissipation pipe 602 from dripping onto the battery pack 5.

[0055] Working principle of the present invention:

[0056] The present invention uses a non-immersion liquid cooling method to cool the battery pack 5, that is, the heat dissipation of the battery pack 5 is achieved by placing the battery pack 5 close to the heat dissipation pipe 602. The specific method is as follows;

[0057] 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. Figure 5 The liquid cooling liquid inside the liquid outlet pipe 401 is passed into the liquid separation head 601, and the liquid separation 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 separation head 601 and is discharged from the liquid inlet pipe 402, thereby circulating to achieve the purpose of heat dissipation of the battery pack 5.

[0058] During actual use of the present invention, if the temperature of the heat dissipation pipe 602 is much lower than the ambient temperature, water vapor in the air will easily condense into small water droplets when encountering the low-temperature surface of the heat dissipation pipe 602. Since the battery pack 5 of the present application is cooled by being close to the heat dissipation pipe 602, water droplets can easily drip onto the battery pack 5, causing short circuit damage to the battery pack 5.

[0059] Based on this, the present invention pushes the battery holder 7 through the cylinder 10, 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, and prevents water droplets on the surface of the heat dissipation pipe 602 from dripping onto the battery pack 5;

[0060] During the movement of the battery holder 7, the battery holder 7 pulls the limit block 801 to move via the rope 809. The limit block 801 pushes the slider 803 to slide along the slide groove 805 via the connecting rod 802. The slider 803 squeezes the hose 603 via the pressure head 804, slowing down the flow rate of the liquid inside the heat dissipation pipe 602. The temperature of the heat dissipation pipe 602 rises relatively, making the temperature of the heat dissipation pipe 602 approach the ambient temperature, thereby preventing the formation of water droplets.

[0061] As the slider 803 slides along the chute 805, it drives the push plate 904 thereon to move synchronously. With the cooperation of the active and driven inclined blocks 905 and 903, the push plate 904, through the active inclined block 905, drives the liquid absorbing sleeve 901 to move closer to the heat dissipation pipe 602, causing the absorbent sponge 907 inside the liquid absorbing sleeve 901 to cover the heat dissipation pipe 602 and absorb the liquid droplets on the heat dissipation pipe 602. Finally, the cylinder 10 drives the battery holder 7 and battery pack 5 to return to their original position. During the return of the battery holder 7, the rope 809 relaxes, and the slider 803 and the liquid absorbing sleeve 901 are reset under the action of the spring 1 806.

[0062] Another way of using the present invention is to first push the battery holder 7 and the battery pack 5 to move synchronously through the cylinder 10, so that the battery pack 5 is 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 slide groove 805 through the connecting rod 802, so that the slider 803 squeezes the hose 603 through the pressure head 804, slowing down the liquid flow rate inside the heat dissipation pipe 602, and the temperature of the heat dissipation pipe 602 is relatively increased, so that the temperature of the heat dissipation pipe 602 approaches the ambient temperature, and the formation of water droplets is suppressed; at the same time, the battery pack 5 is pushed to slide along the guide bar on the battery holder 7, so that the battery pack 5 is close to the heat dissipation pipe 602, so that the battery pack 5 is closer to the heat dissipation pipe 602. This method suppresses the formation of water droplets on the surface of the heat dissipation pipe 602 while ensuring the heat dissipation effect of the battery pack 5.
