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 been increasing. However, the power supply process of electric energy in new energy is usually carried out simultaneously with power generation, resulting in a large difference between the supply of electric energy in the power grid and the actual power consumption. In response to this, 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 will be 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 appeared in the prior art.

[0003] Existing liquid-cooled energy storage containers cool the air in the box by setting up heat exchange pipes in the box, and coolant flows through the heat exchange pipes, so as to achieve the effect of cooling the battery pack in 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 in the energy storage container during the day and to keep the battery pack warm and heated at night. To ensure 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 insulation and heating devices respectively, which adds additional costs, and the heat absorbed by the liquid cooling and cooling device 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 the existing energy storage containers need to be equipped with liquid cooling devices and thermal insulation and heating devices respectively in areas with large temperature differences, resulting in high costs and low energy utilization.

[0005] A liquid cooling system according to an embodiment of the present invention comprises 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 a battery pack is placed above the electric slider; the liquid cooling component comprises 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 driving device connected to the first guide pipe, and a heat sink arranged at the bottom of the heat exchanger; the heat preservation component comprises a first guide pipe arranged on the A second flow guide pipe on both sides of the box body, a water tank connected to the second flow guide pipe, a second drive device connected to the second flow guide pipe, and a valve arranged on the second flow guide pipe, the heat sink is at least partially placed in the water tank; a transmission component for connecting the electric slider and the valve is provided on an electric slider close to the valve, so that when the electric slider moves back and forth, the second flow guide pipe and the water tank are controlled to be on and off 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, by setting a liquid cooling component and a heat preservation component for heat dissipation and heat preservation of the battery pack of the energy storage container during the day and night, enables the battery pack of the energy storage container to work at a suitable temperature, thereby enabling the energy storage container to operate normally in areas with large temperature differences between day and night. Specifically, during the day, multiple battery packs are driven away from each other by an electric slider to increase the distance between adjacent battery packs and improve the heat dissipation effect of the battery packs. One of the battery packs controls the partition between the second guide pipe and the water tank through a transmission component when the electric slider moves, and then the first driving device allows the coolant to pass through the first guide pipe into the cooling pipes on both sides of the battery pack to dissipate heat for each battery pack, and then flows back to the heat exchanger, so that the coolant circulates in the first guide pipe, and the heat exchanger dissipates heat through the heat sink, and transfers the heat to the water in the water tank, thereby both cooling the coolant and storing part of the heat in the water in the water tank. When the battery pack needs to be kept warm at night, the battery pack is driven to reset close to each other by the electric slider, so that the second guide pipe is connected to the water tank, and then the water in the water tank is driven to circulate in the second guide pipe by the second driving device. Since the water in the water tank is heated by the heat sink during the day, the battery pack is kept warm, and the heat dissipated during the day is recycled, thereby improving the energy recovery efficiency. And there is no need to configure additional heating equipment for heating and keeping the battery pack warm, which reduces the cost. Therefore, the present invention solves the problem that the existing energy storage container needs to be equipped with a liquid cooling device and a heat preservation and heating device in areas with large temperature differences, resulting in high costs and low energy utilization.

[0020] 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 component 30 disposed on one side of the bracket 10, and a heat preservation component 40 disposed on both sides of the box 70, and a battery pack 80 is placed above the electric slider 20, wherein: The liquid cooling assembly 30 includes a first guide pipe 31 disposed on the top of the box body 70, cooling pipes 32 disposed 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 disposed at the bottom of the heat exchanger 34; the heat preservation assembly 40 includes a second guide pipe 41 disposed 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 disposed at the bottom of the heat exchanger 34. Device 43, and a valve 44 arranged on the second guide pipe 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 pipe 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.

[0021] It can be understood that by providing the liquid cooling assembly 30 and the heat preservation assembly 40 for heat dissipation and heat preservation 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 is used to drive multiple battery packs 80 to move 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 tube 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 tube 31 into the cooling tubes 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 tube 31, and the heat exchanger 34 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 reset close to each other, so that the second guide pipe 41 is connected to the water tank 42, and then the second driving device 43 drives the water in the water tank 42 to circulate in the second guide pipe 41. Since the water in the water tank 42 is heated by the heat sink 36 during the day, the battery pack 80 is kept warm, and the heat dissipated during the day is recycled, thereby improving the energy recovery efficiency. There is no need to configure additional heating equipment for heating and keeping the battery pack 80 warm, which reduces costs. Therefore, the present invention solves the problem that the existing energy storage container needs to be equipped with a liquid cooling device and a heat preservation and heating device in areas with large temperature differences, resulting in high costs and low energy utilization.

[0022] Specifically, two valves 44 are provided on one side of the water tank 42, and the two valves 44 are used to control the on-off between the water tank 42 and the two second flow guide pipes 41, respectively. The valve 44 includes a ball valve portion 441, a valve core portion 442 disposed in 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 specific implementation, the transmission component 21 is driven to move simultaneously by the movement of the electric slider 20, so that the rack 213 on the transmission component 21 and the first column gear 443 on the valve 44 are meshed, and the first column gear 443 is driven to rotate, thereby driving the valve core portion 442 of the valve 44 to rotate, thereby realizing the on-off control of the valve 44, so that the electric slider 20 and the valve 44 are linked. When the battery pack 80 needs to dissipate heat during the day, the adjacent battery packs 80 are spread out to improve the heat dissipation effect between the battery packs 80, and the water tank 42 is separated from the second guide tube 41, so that when the water in the water tank 42 dissipates heat to the heat exchanger 34 and stores heat, the heated water will not enter the second guide tube 41 to heat the battery pack 80. When the battery pack 80 needs to be heated at night, the electric slider 20 is used to bring the battery packs 80 closer to each other, and the water tank 42 is connected to the second guide tube 41, so that the battery pack 80 is heated and kept warm by the water heated during the day in the water tank 42, thereby improving energy utilization efficiency. In addition, the transmission component 21 is provided with two parallel cross bars 212, so that the two valves 44 can be controlled to be on and off at the same time through one electric slider 20, so as to reduce the setting of parts and reduce costs.

[0023] In addition, the cooling pipe 32 includes two symmetrically arranged vertical parts 321 and a curved part 322 arranged between the two vertical parts 321. The multiple curved parts 322 are evenly distributed along the length direction of the vertical parts 321. The two ends of the curved part 322 are respectively used to connect the two vertical parts 321. The cooling pipe 32 is arranged between the two heat exchange plates 37. In the specific implementation, multiple cooling sources are distributed outside the battery pack 80 through multiple evenly distributed curved parts 322 to improve the heat dissipation effect of the cooling pipe 32. In addition, by setting the curved part 322, the contact area between the cooling pipe 32 and the outside is larger in 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 setting the heat exchange plate 37, the heat exchange plate 37 is in direct contact with the cooling pipe 32, and the heat exchange plate 37 is provided with multiple heat sinks, so that the cooling effect of the cooling pipe 32 is further improved by increasing the heat exchange area.

[0024] 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 serpentinely distributed in the insulation plate 45. In actual use, by setting the insulation plate 45, the inside of the energy storage box is isolated from the outside world, so as to avoid 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, a plurality of 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.

[0025] By way of example but not limitation, in some optional embodiments, the liquid cooling system further comprises an air flow assembly 50, the air flow assembly 50 comprises a mounting frame 51 disposed on both sides of the box body 70, a plurality of fans 52 disposed on the mounting frame 51, guide rods 53 and screw rods 54 disposed on both sides of the mounting frame 51, and a third driving device 55 disposed on one side of the mounting frame 51, the mounting frame 51 is provided with a guide hole 511 and a threaded hole 512 respectively adapted to the guide rod 53 and the screw rod 54, and the third driving device 55 drives the screw rod 54 to rotate forward and reversely so that the mounting frame 51 moves up and down along the guide rod 53. Specifically, the transmission rod of the third driving device 55 and the bottom of the screw rod 54 are both provided with a second column gear 56, and the two second column gears 56 are meshed with each other. In a specific implementation, a fan 52 and a third driving device 55 are arranged on the mounting frame 51, so that the third driving device 55 drives the two second column gears 56 to mesh and rotate with each other through the transmission rod, and then drives the screw 54 to rotate, so that through the cooperation of the screw 54 and the threaded hole 512, the fan 52 will move up and down with the mounting frame 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.

[0026] 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, and 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 a straight tooth portion 461 is provided to cooperate 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 coordination 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, and thus ensuring that the temperature of the coolant in the first guide pipe 31 is low enough.

[0027] Specifically, a plurality of staggered stirring rods 462 are provided at the other end of the stirring rod 46. In addition, 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. In addition, by staggered stirring rods 462, the stirring direction of the stirring rod 46 is disturbed, so that turbulence or turbulence is generated to improve the stirring effect.

When the housing door 71 is closed, the housing door 71 squeezes the piston rod 64 so that the gas flows from the piston cylinder 62 to the airbag ring 61. In addition, in a specific implementation, by arranging the cooperation between the airbag ring 61 and the piston cylinder 62, the piston rod 64 is squeezed when the housing 70 is closed, so that the gas in the piston cylinder 62 flows to the airbag ring 61, and then 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, thereby ensuring the heat preservation effect in 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.

[0029] In summary, the present invention provides a liquid cooling component 30 and a 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, so that the battery pack 80 of the energy storage container can work 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 is used to drive multiple battery packs 80 to move 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 tube 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 tube 31 into the cooling tubes 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 tube 31, and the heat exchanger 34 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 reset close to each other, so that the second guide pipe 41 is connected to the water tank 42, and then the second driving device 43 drives the water in the water tank 42 to circulate in the second guide pipe 41. Since the water in the water tank 42 is heated by the heat sink 36 during the day, the battery pack 80 is kept warm, and the heat dissipated during the day is recycled, thereby improving the energy recovery efficiency. There is no need to configure additional heating equipment for heating and keeping the battery pack 80 warm, which reduces costs. Therefore, the present invention solves the problem that the existing energy storage container needs to be equipped with a liquid cooling device and a heat preservation and heating device in areas with large temperature differences, resulting in high costs and low energy utilization.

[0030] In addition, the present invention also provides a liquid-cooled energy storage container, which includes the above-mentioned liquid cooling system.

In addition, in the specific implementation, it can also be determined whether to set a heating device according to the actual situation to prevent the insufficient heat stored in the water tank 42 during the day, and the sudden change in weather causes the temperature to drop sharply, so that the battery pack 80 cannot maintain a sufficient temperature under the action of the insulation component 40.
