Description

Technical Field

[0001] The present invention relates to the field of liquid cooling technology, and in particular to a liquid cooling system and a liquid cooling energy storage container. Background Art

[0002] With the transformation of the global energy structure and the vigorous development of renewable energy, the share of new energy technologies in the energy market has continued to increase. However, the power supply process and power generation of new energy are usually carried out simultaneously, resulting in a large discrepancy between the power supply in the power grid and the actual power consumption. Energy storage technology has become a research hotspot, among which container energy storage systems have attracted widespread attention due to their high efficiency, safety and flexibility. However, during the use of container energy storage systems, a large amount of heat is generated due to the operation of various devices in the energy storage system. If the heat dissipation effect of the energy storage system is not good, it is easy to affect the normal operation of various devices and even cause damage to the energy storage system. In response to this, energy storage box systems that use liquid cooling for cooling have emerged in the existing technology.

[0003] Existing liquid-cooled energy storage containers cool the air inside the container by installing heat exchange pipes inside the container, through which coolant flows, thereby achieving the effect of cooling the battery pack inside the liquid-cooled energy storage container. However, since areas rich in solar energy are prone to large temperature differences between day and night, liquid-cooled energy storage containers used in conjunction with new energy power generation equipment have to solve the need to dissipate heat for the battery pack inside the energy storage container during the day and to keep the battery pack warm and heated at night. This ensures that the battery pack can be within the normal temperature range, thereby ensuring the service life of the battery pack. In order to solve this problem, existing liquid-cooled energy storage containers usually need to be equipped with liquid cooling and cooling devices and heat preservation and heating devices separately, which adds additional costs, and the heat absorbed by the liquid cooling and cooling devices during cooling will be wasted, resulting in low energy utilization. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a liquid cooling system and a liquid cooling energy storage container, aiming to solve the problem that existing energy storage containers need to be equipped with liquid cooling devices and thermal insulation and heating devices separately in areas with large temperature differences, resulting in high costs and low energy utilization.

[0005] According to an embodiment of the present invention, a liquid cooling system includes a bracket arranged in a box body, an electric slider arranged on the bracket, a liquid cooling component arranged on one side of the bracket, and a heat preservation component arranged on both sides of the box body, wherein the battery pack is placed above the electric slider; the liquid cooling component includes a first guide pipe arranged on the top of the box body, cooling pipes arranged on both sides of the electric slider, a telescopic pipe for connecting the cooling pipe and the first guide pipe, a heat exchanger connected to the first guide pipe, a first drive device connected to the first guide pipe, and a heat dissipation plate arranged at the bottom of the heat exchanger; the heat preservation component includes a first guide pipe arranged on the The second flow guide pipes on both sides of the box body, the water tank connected to the second flow guide pipes, the second drive device connected to the second flow guide pipes, and the valve arranged on the second flow guide pipes, the heat dissipation plate is at least partially placed in the water tank; a transmission component for connecting the electric slider and the valve is provided on one of the electric sliders near the valve, so that when the electric slider moves back and forth, the connection and disconnection between the second flow guide pipes and the water tank are controlled by the transmission component; the bracket is arranged in a compartment of the box body, and the first drive device, the second drive device, the heat exchanger and the water tank are arranged in another compartment of the box body.

[0006] The present invention provides a liquid cooling assembly and a thermal insulation assembly for dissipating heat and preserving heat from the battery packs of the energy storage container during the day and night, respectively, so that the battery packs of the energy storage container can operate at an appropriate temperature, thereby enabling the energy storage container to operate normally in areas with large temperature differences between day and night. Specifically, during the day, an electric slider drives multiple battery packs away from each other to increase the distance between adjacent battery packs and improve the heat dissipation effect of the battery packs. When the electric slider moves, one of the battery packs controls the separation between the second guide pipe and the water tank through a transmission component. Then, the first drive device allows the coolant to pass through the first guide pipe and enter the cooling pipes on both sides of the battery pack to dissipate heat for each battery pack, and then flow back to the heat exchanger, so that the coolant circulates in the first guide pipe. The heat exchanger then dissipates heat through the heat sink and transfers the heat to the water in the water tank, thereby both cooling the coolant and storing some heat in the water in the water tank. When the battery pack needs to be kept warm at night, the electric slider drives the battery packs toward each other and resets them, connecting the second guide tube to the water tank. The second drive device then drives the water in the water tank to circulate in the second guide tube. Since the water in the water tank is heated by the heat sink during the day, it insulates the battery pack and recycles the heat dissipated during the day, improving energy recovery efficiency. There is no need for additional heating equipment to heat and insulate the battery pack, reducing costs. Therefore, the present invention solves the problem that existing energy storage containers require separate liquid cooling and heating devices in areas with large temperature differences, resulting in high costs and low energy utilization.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] See also Figures 1 to 14 , which shows a liquid cooling system in an embodiment of the present invention, including a bracket 10 disposed in a box 70, an electric slider 20 disposed on the bracket 10, a liquid cooling assembly 30 disposed on one side of the bracket 10, and thermal insulation assemblies 40 disposed on both sides of the box 70. A battery pack 80 is placed above the electric slider 20, wherein:

[0037] The liquid cooling assembly 30 includes a first guide pipe 31 provided on the top of the box body 70, cooling pipes 32 provided on both sides of the electric slider 20, a telescopic pipe 33 for connecting the cooling pipe 32 and the first guide pipe 31, a heat exchanger 34 connected to the first guide pipe 31, a first driving device 35 connected to the first guide pipe 31, and a heat sink 36 provided at the bottom of the heat exchanger 34; the heat preservation assembly 40 includes a second guide pipe 41 provided on both sides of the box body 70, a water tank 42 connected to the second guide pipe 41, a second driving device 35 connected to the second guide pipe 41, and a heat sink 36 provided at the bottom of the heat exchanger 34. Device 43, and a valve 44 arranged on the second guide tube 41, the heat sink 36 is at least partially placed in the water tank 42; an electric slider 20 near the valve 44 is provided with a transmission component 21 for connecting the electric slider 20 and the valve 44, so that when the electric slider 20 moves back and forth, the connection between the second guide tube 41 and the water tank 42 is controlled by the transmission component 21; the bracket 10 is arranged in a compartment of the box body 70, and the first drive device 35, the second drive device 43, the heat exchanger 34 and the water tank 42 are arranged in another compartment of the box body 70.

[0038] It can be understood that by providing the liquid cooling component 30 and the thermal insulation component 40 for heat dissipation and thermal insulation of the battery pack 80 of the energy storage container during the day and night, respectively, the battery pack 80 of the energy storage container can operate at a suitable temperature, thereby allowing the energy storage container to operate normally in areas with large temperature differences between day and night. Specifically, during the day, the electric slider 20 drives multiple battery packs 80 away from each other to increase the distance between adjacent battery packs 80 and improve the heat dissipation effect of the battery packs 80. One of the battery packs 80 controls the partition between the second guide pipe 41 and the water tank 42 through the transmission component 21 when the electric slider 20 moves, and then the first driving device 35 allows the coolant to pass through the first guide pipe 31 into the cooling pipes 32 on both sides of the battery pack 80 to dissipate heat for each battery pack 80, and return to the heat exchanger 34, so that the coolant circulates in the first guide pipe 31, and the heat exchanger 34 then dissipates heat through the heat sink 36 and transfers the heat to the water in the water tank 42, thereby both cooling the coolant and storing part of the heat in the water in the water tank 42. When the battery pack 80 needs to be kept warm at night, the electric slider 20 drives the battery pack 80 to move closer together and reset, connecting the second guide tube 41 to the water tank 42. The second drive device 43 then drives the water in the water tank 42 to circulate in the second guide tube 41. Since the water in the water tank 42 is heated by the heat sink 36 during the day, it can keep the battery pack 80 warm and recycle the heat dissipated during the day, thereby improving energy recovery efficiency. There is no need to configure additional heating equipment to heat and keep the battery pack 80 warm, reducing costs. Therefore, the present invention solves the problem that existing energy storage containers need to be equipped with liquid cooling devices and heat preservation and heating devices separately in areas with large temperature differences, resulting in high costs and low energy utilization.

[0039] Specifically, two valves 44 are provided on one side of the water tank 42, and the two valves 44 are respectively used to control the flow between the water tank 42 and the two second flow guide tubes 41. The valve 44 includes a ball valve portion 441, a valve core portion 442 disposed within the ball valve portion 441, and a first column gear 443 disposed outside the ball valve portion 441 and connected to the valve core portion 442. The transmission component 21 includes a vertical rod 211 connected to the electric slider 20, a horizontal rod 212 disposed at both ends of the vertical rod 211, and a rack 213 disposed on the horizontal rod 212 and adapted to the first column gear 443. In a specific implementation, the movement of the electric slider 20 drives the transmission component 21 to move simultaneously, causing the rack 213 on the transmission component 21 to engage with the first column gear 443 on the valve 44, and driving the first column gear 443 to rotate, thereby driving the valve core portion 442 of the valve 44 to rotate, thereby achieving on-off control of the valve 44, and linking the electric slider 20 with the valve 44. During the day, when the battery packs 80 need to dissipate heat, adjacent battery packs 80 are spread out to improve the heat dissipation effect between the battery packs 80. The water tank 42 is separated from the second flow conduit 41. As the water in the water tank 42 dissipates heat from the heat exchanger 34 and stores heat, the heated water does not enter the second flow conduit 41 to heat the battery packs 80. When the battery packs 80 need to be heated at night, the electric slider 20 is used to bring the battery packs 80 closer together, and the water tank 42 is connected to the second flow conduit 41. This allows the water heated during the day in the water tank 42 to heat and maintain the battery packs 80, thereby improving energy utilization efficiency. In addition, the transmission component 21 uses two parallel cross bars 212, so that the electric slider 20 can simultaneously control the opening and closing of two valves 44, thereby reducing the number of components and reducing costs.

[0040] In addition, the cooling pipe 32 includes two symmetrically arranged vertical portions 321 and a curved portion 322 arranged between the two vertical portions 321. The multiple curved portions 322 are evenly distributed along the length direction of the vertical portions 321. The two ends of the curved portion 322 are respectively used to connect the two vertical portions 321. The cooling pipe 32 is arranged between the two heat exchange plates 37. In a specific implementation, multiple cooling sources are distributed outside the battery pack 80 by means of multiple evenly distributed curved portions 322, so as to improve the heat dissipation effect of the cooling pipe 32. In addition, by providing the curved portion 322, the contact area between the cooling pipe 32 and the outside world is larger within a limited space, that is, the heat exchange area is larger, thereby further improving the heat dissipation effect of the cooling pipe 32. In addition, by additionally providing a heat exchange plate 37, the heat exchange plate 37 is in direct contact with the cooling pipe 32, and a plurality of heat sinks are provided on the heat exchange plate 37, thereby further improving the cooling effect of the cooling pipe 32 by increasing the heat exchange area.

[0041] Specifically, the insulation component 40 also includes insulation plates 45 arranged on both sides of the box body 70, and the second flow guide tube 41 is distributed in a serpentine shape inside the insulation plate 45. In actual use, by providing the insulation plate 45, the interior of the energy storage box is isolated from the outside world, so as to prevent the outside temperature from having a great influence on the internal temperature. Then, during the day, after the internal temperature is quickly lowered by the liquid cooling component 30, the internal temperature is stably maintained within a specific range through the insulation plate 45. At night, after the battery pack 80 is heated by the insulation component 40, the internal temperature is prevented from losing quickly through the insulation plate 45. In addition, through the serpentine setting of the second flow guide tube 41, multiple large-area heat sources are provided in the box body 70, so that the temperature of each battery pack 80 can be quickly increased and maintained within a specific range at night.

[0042] By way of example and not limitation, in some optional embodiments, the liquid cooling system further includes an air flow assembly 50, which includes mounting frames 51 disposed on both sides of the housing 70, a plurality of fans 52 disposed on the mounting frames 51, guide rods 53 and screws 54 disposed on both sides of the mounting frames 51, and a third drive device 55 disposed on one side of the mounting frame 51. The mounting frame 51 is provided with guide holes 511 and threaded holes 512 that respectively mate with the guide rods 53 and screws 54. The third drive device 55 drives the screws 54 in forward and reverse rotation to move the mounting frame 51 up and down along the guide rods 53. Specifically, the transmission rod of the third drive device 55 and the bottom of the screw 54 are both provided with second column gears 56, which mesh with each other. In a specific implementation, a fan 52 and a third driving device 55 are provided on the mounting bracket 51, so that the third driving device 55 drives the two second column gears 56 to engage with each other and rotate through the transmission rod, thereby driving the screw 54 to rotate. Therefore, through the cooperation between the screw 54 and the threaded hole 512, the fan 52 will move up and down with the mounting bracket 51, so that the air in the box 70 is stirred by the fan 52, so as to improve the heat dissipation effect of the battery pack 80.

[0043] In addition, a third driving device 55 is fixed between two mounting plates 57. A transmission rod of the third driving device 55 passes through the mounting plate 57 and is provided with a turntable 58 on the top. A swing rod 59 is provided on the turntable 58. A stirring rod 46 connected to the swing rod 59 is provided in the water tank 42. The swing rod 59 includes a straight rod portion 591 and an arc portion 592 arranged at one end of the straight rod portion 591. A straight groove 593 is provided on the straight rod portion 591. A slider 581 adapted to the straight groove 593 is provided on the turntable 58. The center of the arc portion 592 is rotatably connected to the mounting plate 57 through a rotating shaft 594. An external tooth portion 595 is provided on the outer side of the arc portion 592. One end of the stirring rod 46 extends out of the water tank 42 and is provided with a straight tooth portion 461. The straight tooth portion 461 is adapted to the external tooth portion 595. When in use, a stirring rod 46 is further provided in the water tank 42, one end of which is supported by a support member extending from the box body 70, and is provided with a straight tooth portion 461 that cooperates with the outer tooth portion 595 of the swing rod 59, so that the third driving device 55 drives the screw 54, so that when the fan 52 moves up and down, the third driving device 55 will also drive the turntable 58 to rotate, so that the slider 581 on the turntable 58 cooperates with the linear groove 593, driving the swing rod 59 to rotate around the rotating shaft 594, so that the swing rod 59 swings back and forth, driving the stirring rod 46 to move back and forth in the water tank 42, so that during the daytime, the heat dissipation effect in the box body 70 is improved by the fan 52, and the water flow in the water tank 42 is stirred in cooperation with the stirring rod 46, so as to avoid the local temperature at the contact point between the heat sink 36 and the water tank 42 being too high, affecting the heat dissipation effect of the heat sink 36, thereby ensuring that the temperature of the coolant in the first guide pipe 31 is sufficiently low.

[0044] Specifically, the other end of the stirring rod 46 is provided with a plurality of staggered stirring rods 462. Furthermore, in a specific implementation, by providing a plurality of stirring rods 462 on the stirring rod 46, the stirring range is increased, and the stirring effect of the stirring rod 46 is improved. Furthermore, the staggered stirring rods 462 disrupt the stirring direction of the stirring rod 46, thereby generating turbulent or turbulent flow, thereby improving the stirring effect.

[0045] In addition, the liquid cooling system also includes a sealing assembly 60, which includes an elastic airbag ring 61, a piston cylinder 62 disposed in a housing 70, a connecting tube 63 connected to the airbag ring 61, and a piston rod 64 connected to the piston cylinder 62. The housing 70 and the housing door 71 are provided with a receiving groove 72 for accommodating the airbag ring 61. The piston rod 64 faces the housing door 71. When the housing door 71 is closed, the housing door 71 squeezes the piston rod 64, allowing gas to flow from the piston cylinder 62 to the airbag ring 61. In addition, in a specific implementation, by arranging the airbag ring 61 and the piston cylinder 62 to cooperate, when the housing 70 is closed, the piston rod 64 is squeezed, causing the gas in the piston cylinder 62 to flow to the airbag ring 61. Furthermore, when the housing door 71 is closed, the airbag ring 61 fills or even partially squeezes the receiving groove 72, so that the housing 70 is relatively sealed from the outside world, thereby ensuring the heat preservation effect within the housing 70. When the box body 70 is opened, the gas is squeezed back into the piston cylinder 62 under the action of the elastic restoring force of the airbag ring 61 itself, so that the piston rod 64 is reset.

[0046] In summary, the present invention provides a liquid cooling assembly 30 and a thermal insulation assembly 40 for heat dissipation and thermal insulation of the battery pack 80 of the energy storage container during the day and night, respectively, so that the battery pack 80 of the energy storage container can operate at a suitable temperature, thereby allowing the energy storage container to operate normally in areas with large temperature differences between day and night. Specifically, during the day, the electric slider 20 drives multiple battery packs 80 away from each other to increase the distance between adjacent battery packs 80 and improve the heat dissipation effect of the battery packs 80. One of the battery packs 80 controls the partition between the second guide pipe 41 and the water tank 42 through the transmission component 21 when the electric slider 20 moves, and then the first driving device 35 allows the coolant to pass through the first guide pipe 31 into the cooling pipes 32 on both sides of the battery pack 80 to dissipate heat for each battery pack 80, and return to the heat exchanger 34, so that the coolant circulates in the first guide pipe 31, and the heat exchanger 34 then dissipates heat through the heat sink 36 and transfers the heat to the water in the water tank 42, thereby both cooling the coolant and storing part of the heat in the water in the water tank 42. When the battery pack 80 needs to be kept warm at night, the electric slider 20 drives the battery pack 80 to move closer together and reset, connecting the second guide tube 41 to the water tank 42. The second drive device 43 then drives the water in the water tank 42 to circulate in the second guide tube 41. Since the water in the water tank 42 is heated by the heat sink 36 during the day, it can keep the battery pack 80 warm and recycle the heat dissipated during the day, thereby improving energy recovery efficiency. There is no need to configure additional heating equipment to heat and keep the battery pack 80 warm, reducing costs. Therefore, the present invention solves the problem that existing energy storage containers need to be equipped with liquid cooling devices and heat preservation and heating devices separately in areas with large temperature differences, resulting in high costs and low energy utilization.

[0047] The present invention also provides a liquid-cooled energy storage container, which includes the aforementioned liquid cooling system. By way of example and not limitation, in some optional embodiments, the interior of the liquid-cooled energy storage container's housing 70 is divided into two compartments by a partition. One compartment is provided with a bracket 10, a motorized slider 20 mounted on the bracket 10, and a battery pack 80 mounted on the motorized slider 20. A door 71 is provided on one side of the compartment. The other compartment is provided with a first drive device 35, a second drive device 43, a third drive device 55, a water tank 42, and a heat exchanger 34. Furthermore, adjustable shutters can be provided on the sides of the compartment to control whether the compartment is open to the outside world for heat dissipation or isolated from the outside world to maintain internal temperature, depending on demand. Furthermore, in specific implementations, the installation of a heating device can be determined based on actual conditions to prevent insufficient heat stored in the water tank 42 during the day, resulting in a sudden drop in temperature due to a sudden change in weather, which would prevent the battery pack 80 from maintaining a sufficient temperature under the action of the insulation assembly 40.
