Description

Technical Field

[0001] The present invention relates to the technical field of energy storage cabinets, and more particularly to an energy storage cabinet for a cooling system. Background Art

[0002] Energy storage cabinets are devices used to store energy. Lithium batteries are the core components of energy storage systems and have strict operating temperature requirements. Typically, the tightly packed battery packs within the energy storage cabinet generate significant heat during charging and discharging. If this heat cannot be quickly dissipated, heat can accumulate between the battery packs and lead to large operating temperature differences. This necessitates reliable heat dissipation to maintain normal system operation. Currently, the most common cooling method for energy storage cabinets is air cooling, with some using liquid cooling. Air cooling offers a simple structure, ease of installation, and low cost, but it cannot meet the heat dissipation requirements of large-capacity energy storage systems. Liquid cooling is superior to air cooling, but the system is complex, bulky, expensive, and difficult to install and maintain, making it impractical for widespread use. Existing phase change material cooling technology, which coats the battery surface with phase change material or sandwiches it between adjacent batteries, has demonstrated good thermal efficiency in experiments, making it an optimal green and environmentally friendly solution for energy conservation and environmental protection. Chinese patent publication number CN117712589A discloses a thermal runaway-resistant energy storage cabinet. This cabinet provides excellent water-cooling and heat dissipation for each battery module. It also automatically adjusts the cooling water flow rate within the cooling pipes based on the surface temperature of each battery module, resulting in more efficient and effective heat dissipation. However, while this cabinet can dissipate heat for each battery module, as cooling water flows in through the water inlet pipe and dissipates heat from both sides of the battery module, the cooling water temperature gradually increases due to the temperature of the battery module. This results in a relatively lower temperature on the battery module side of the water inlet pipe than on the water outlet pipe side. This long-term trend leads to uneven heat dissipation across the battery module, shortening its service life. Summary of the Invention

[0003] The purpose of the present invention is to address the shortcomings of the existing technology and provide an energy storage cabinet with a cooling system. This system effectively dissipates heat from the battery modules through phase change materials while simultaneously using a thermostatic component to exchange heat between the cold liquid and hot liquid in the first water inlet pipe and the first water outlet pipe, and the second water inlet pipe and the second water outlet pipe, respectively. The flow rate of the cold liquid is regulated by a regulating component to reduce the temperature difference on both sides of the battery modules and evenly dissipate heat from the battery modules. The technical solutions of the present invention are as follows:

[0006] As a preferred embodiment, the first cooling assembly also includes a first cooling box fixedly arranged on the energy storage cabinet body, a first water supply pipe and a first return pipe fixedly connected to both sides of the first cooling box, a first water pump fixedly connected to the first return pipe, two symmetrically arranged first cooling pipes fixedly connected to the top and bottom of each placement slot, two symmetrically arranged first U-shaped pipes fixedly connected between the two first cooling pipes, a first connecting pipe fixedly arranged in an array on the first water supply pipe, and a second connecting pipe fixedly arranged in an array on the first return pipe, the other ends of the first connecting pipe and the second connecting pipe are respectively fixedly connected to the side walls of the first U-shaped pipes on both sides, and the first water inlet pipe is fixedly connected to the first U-shaped pipe and the first cooling pipe on one side.

[0007] As a preference, the second cooling assembly also includes a second cooling box fixedly arranged on the energy storage cabinet body, a second water supply pipe and a second return water pipe fixedly connected to both sides of the second cooling box, a second water pump fixedly connected to the second return water pipe, two symmetrically arranged second cooling pipes fixedly connected to the top and bottom of each placement slot, two symmetrically arranged second U-shaped pipes fixedly connected between the two second cooling pipes, a third connecting pipe fixedly arranged in an array on the second water supply pipe, and a fourth connecting pipe fixedly arranged in an array on the second return water pipe, the other ends of the third connecting pipe and the fourth connecting pipe are respectively fixedly connected to the side walls of the second U-shaped pipes on both sides, and the second water inlet pipe is fixedly connected to the second U-shaped pipe and the second cooling pipe on one side.

[0008] As a preference, the constant temperature assembly also includes a first exchange tube fixedly connected to the first cooling tube and the constant temperature tube, a second exchange tube fixedly connected to the second cooling tube and the constant temperature tube, the second water outlet pipe fixedly connected to the first U-shaped tube and the first cooling tube, and the first water outlet pipe fixedly connected to the second U-shaped tube and the second cooling tube.

[0009] The control valve of described outer combustion gas heating unit is connected with the control valve in the forward end of each end face of described outer combustion gas heating unit, and the control valve is connected with the control valve in the forward end face.

[0010] As a preference, the regulating valve is configured as a conical structure.

[0011] As a preferred embodiment, mercury is provided in the cylinder.

[0012] The beneficial effects of the present invention are

[0013] The present invention is provided with a first cooling component, a second cooling component and a constant temperature component. When the battery module is to be cooled, the first water pump injects the cold liquid in the first cooling box into the first water inlet pipe and the first cooling pipe through the first water supply pipe, and flows from the first U-shaped pipe through the first connecting pipe into each first cooling pipe below to dissipate heat for the battery module. After the cold liquid absorbs heat, its temperature increases. Subsequently, the hot liquid passes through the first exchange pipe to reach the constant temperature pipe, and flows from the first water outlet pipe and the second connecting pipe into the first U-shaped pipe and the first return pipe on the other side and the first cooling box to be cooled and circulated for heat dissipation. At the same time, the second water pump injects the cold liquid in the second cooling box into the first water inlet pipe and the first cooling pipe through the second water supply pipe. The water pipe is injected into the second water inlet pipe and the second cooling pipe, and flows from the second U-shaped pipe through the third connecting pipe into the second cooling pipes below to dissipate heat for the battery module. After the cold liquid absorbs heat, its temperature increases. Then the hot liquid passes through the second exchange pipe to reach the constant temperature pipe, and flows from the second water outlet pipe and the fourth connecting pipe into the second U-shaped pipe and the second return pipe and the second cooling box on the other side for cooling and then circulation to dissipate heat. Since there are the first water inlet pipe and the second water inlet pipe in the constant temperature pipe, the cold liquid flowing out of the first water inlet pipe and the second water inlet pipe can exchange heat with the hot liquid in the first water outlet pipe and the second water outlet pipe. This method can reduce the temperature difference on both sides of the battery module.

[0014] The present invention is provided with a regulating assembly. When there is a temperature difference between the hot liquid in the first water outlet pipe and the second water outlet pipe, the mercury in the regulating tube and the cylinder on the side with the higher temperature expands more, thereby pushing the piston, piston rod, connecting rod, sliding rod and regulating valve to move to the side away from the cylinder. Here, the conical head of the regulating valve is away from the inlet of the cold liquid, so that the water flow of the cold liquid is larger, thereby performing heat exchange with the hot liquid. At the same time, the conical head of the regulating valve on the other side is pushed close to the inlet of the cold liquid, so that the water flow of the cold liquid becomes smaller, thereby balancing the temperatures on both sides, making the temperatures on both sides consistent, and ensuring uniform cooling and heat dissipation of the battery module.

[0015] In summary, the present invention has the advantages of good heat dissipation effect and high speed, and is suitable for the technical field of energy storage cabinets. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings. Example 1

[0033] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention. Figures 1 to 14 As shown, an energy storage cabinet of a cooling system includes an energy storage cabinet body 1, a placement assembly 2 is provided in the energy storage cabinet body 1, a first cooling assembly 3 is provided in the placement assembly 2, the first cooling assembly 3 includes a first water inlet pipe 31, a second cooling assembly 4 is provided on one side of the first cooling assembly 3, the second cooling assembly 4 includes a second water inlet pipe 41, and the first cooling assembly 3 and the second cooling assembly 4 are both provided with a constant temperature assembly 5, the constant temperature assembly 5 includes a constant temperature pipe 51 provided on the first water inlet pipe 31 and the second water inlet pipe 41, and a first water outlet pipe 52 and a second water outlet pipe 53 provided on the constant temperature pipe 51, the constant temperature pipe 51 is used to heat exchange hot liquid in the first water outlet pipe 52 and the second water outlet pipe 53 with cold liquid in the first water inlet pipe 31 and the second water inlet pipe 41, respectively; an adjustment assembly 6 is provided on the constant temperature assembly 5, the first cooling assembly 3 and the second cooling assembly 4 are both used to cool a plurality of battery modules 7 on the placement assembly 2, and the adjustment assembly 6 is used to adjust the water flow of the cold liquid in the first water inlet pipe 31 and the second water inlet pipe 41.

[0034] like Figure 2 As shown, the placement assembly 2 includes a placement rack 21 fixedly arranged in the energy storage cabinet body 1 and a placement slot 22 opened on the placement rack 21 , and the battery module 7 is placed in the placement slot 22 .

[0035] like Figure 7 and Figure 8As shown, the first cooling assembly 3 also includes a first cooling box 32 fixedly arranged on the energy storage cabinet body 1, a first water supply pipe 33 and a first return pipe 34 fixedly connected to both sides of the first cooling box 32, a first water pump 35 fixedly connected to the first return pipe 34, two symmetrically arranged first cooling pipes 36 fixedly connected to the top and bottom of each placement slot 22, two symmetrically arranged first U-shaped pipes 37 fixedly connected between the two first cooling pipes 36, a first connecting pipe 38 fixedly arranged in an array on the first water supply pipe 33, and a second connecting pipe 39 fixedly arranged in an array on the first return pipe 34. The other ends of the first connecting pipe 38 and the second connecting pipe 39 are respectively fixedly connected to the side walls of the first U-shaped pipe 37 on both sides, and the first water inlet pipe 31 is fixedly connected to the first U-shaped pipe 37 and the first cooling pipe 36 on one side. When the cold liquid in the first water inlet pipe 31 and the second water inlet pipe 41 starts to flow at the same time, the temperature of the cold liquid is the lowest when it just contacts the battery module 7, and it absorbs during the flow. The heat of the battery module 7 causes the temperature of the battery module 7 to rise, which will cause the overall temperature of the battery module 7 to be uneven, with the temperature on both sides being lower than that in the middle, affecting the service life and effect of the battery module 7. During use, when the battery module 7 is to be cooled, the first water pump 35 injects the cold liquid in the first cooling box 32 into the first water inlet pipe 31 and the first cooling pipe 36 through the first water supply pipe 33, and flows from the first U-shaped pipe 37 through the first connecting pipe 38 into the first cooling pipes 36 below to dissipate heat from the battery module 7. After the cold liquid absorbs heat, its temperature rises. Subsequently, the hot liquid passes through the first exchange pipe 54 and reaches the constant temperature pipe 51, and flows from the second water outlet pipe 53 and the second connecting pipe 39 into the first U-shaped pipe 37 and the first return pipe 34 on the other side, and the first cooling box 32 for cooling and then circulation to dissipate heat. Since there is a second water inlet pipe 41 in the constant temperature pipe 51, the cold liquid flowing out of the second water inlet pipe 41 can exchange heat with the hot liquid in the second water outlet pipe 53. This method can reduce the temperature difference on both sides of the battery module 7.

[0036] like Figures 12 to 14As shown, the second cooling assembly 4 also includes a second cooling box 42 fixedly arranged on the energy storage cabinet body 1, a second water supply pipe 43 and a second return pipe 44 fixedly connected to both sides of the second cooling box 42, a second water pump 45 fixedly connected to the second return pipe 44, two symmetrically arranged second cooling pipes 46 fixedly connected to the top and bottom of each placement slot 22, two symmetrically arranged second U-shaped pipes 47 fixedly connected between the two second cooling pipes 46, a third connecting pipe 48 fixedly arranged in an array on the second water supply pipe 43, and a fourth connecting pipe 49 fixedly arranged in an array on the second return pipe 44. The other ends of the third connecting pipe 48 and the fourth connecting pipe 49 are respectively fixed to the side walls of the second U-shaped pipe 47 on both sides. The second water inlet pipe 41 is fixedly connected to the second U-shaped tube 47 and the second cooling tube 46 on one side. During use, when the battery module 7 is cooled, the second water pump 45 injects the cold liquid in the second cooling box 42 into the second water inlet pipe 41 and the second cooling tube 46 through the second water supply pipe 43, and flows from the second U-shaped tube 47 through the third connecting tube 48 into the second cooling tubes 46 below to dissipate heat for the battery module 7. After the cold liquid absorbs heat, its temperature increases. Then, the hot liquid passes through the second exchange tube 55 and reaches the constant temperature tube 51. It flows from the first water outlet pipe 52 and the fourth connecting tube 49 into the second U-shaped tube 47 and the second return water pipe 44 and the second cooling box 42 on the other side for cooling and then circulates to dissipate heat.

[0037] like Figures 3 to 9 As shown, the thermostatic assembly 5 also includes a first exchange tube 54 fixedly connected to the first cooling tube 36 and the thermostatic tube 51, a second exchange tube 55 fixedly connected to the second cooling tube 46 and the thermostatic tube 51, a first water outlet pipe 52 fixedly connected to the first U-shaped tube 37 and the first cooling tube 36, and a second water outlet pipe 53 fixedly connected to the second U-shaped tube 47 and the second cooling tube 46. The thermostatic assembly 5 can reduce the temperature difference on both sides of the battery module 7 to ensure uniform heat dissipation of the battery module 7 as a whole.

[0038] like Figures 9 to 14As shown, the regulating assembly 6 includes a regulating tube 61 fixedly arranged on the first water inlet pipe 31 and the second water inlet pipe 41, a chute 62 provided on the regulating tube 61, a slide rod 63 slidably provided in the chute 62, a regulating valve 64 fixedly provided on the slide rod 63, a first telescopic plate 65 slidably provided in the chute 62, a through groove 66 provided on the thermostatic tube 51, a second telescopic plate 67 slidably provided in the through groove 66, a fixed tube 68 fixedly arranged on the first water outlet pipe 52 and the second water outlet pipe 53, a cylinder 69 fixedly provided on the fixed tube 68, a piston 70 slidably provided in the cylinder 69, and a piston fixedly provided on the piston 70. The piston rod 71, the connecting rod 72 fixedly set on the piston rod 71, the sliding rod 63 passes through the first telescopic plate 65 and the second telescopic plate 67 and is fixedly connected to one side of the first telescopic plate 65 and the second telescopic plate 67, and the other sides of the first telescopic plate 65 and the second telescopic plate 67 are fixedly connected to the inner wall of the slide groove 62 and the through groove 66 respectively. A spring 73 is sleeved on the piston rod 71 and the spring 73 is fixedly connected between the piston 70 and the cylinder 69. The sliding rod 63 is fixedly connected to the connecting rod 72. The two sliding rods 63 are fixedly connected by a fixing rod 74. Among them, the initial positions of the two regulating valves 64 are both in the middle of the regulating pipe 61. When the first water outlet pipe 52 When there is no difference in temperature between the hot liquid in the first outlet pipe 52 and the hot liquid in the second outlet pipe 53, the two regulating valves 64 are in a stationary state. When there is a difference in temperature between the hot liquids, the mercury at the regulating valve 64 on the side with the higher temperature absorbs heat and expands more, thereby adjusting the water flow of the cold liquid in the first water inlet pipe 31 and the second water inlet pipe 41. When in use, when there is a difference in temperature between the hot liquid in the first outlet pipe 52 and the second outlet pipe 53, the mercury in the regulating pipe 61 and the cylinder 69 on the side with the higher temperature expands more, thereby pushing the piston 70, the piston rod 71, the connecting rod 72, the sliding rod 63 and the regulating valve 64 to move to the side away from the cylinder 69. Here, the regulating valve 64 The conical head is away from the inlet of the cold liquid, so that the water flow of the cold liquid is larger, thereby performing heat exchange with the hot liquid. At the same time, the conical head of the regulating valve 64 on the other side is pushed closer to the inlet of the cold liquid, so that the water flow of the cold liquid becomes smaller, thereby balancing the temperatures on both sides and making the temperatures on both sides consistent, ensuring uniform cooling and heat dissipation of the battery module 7. In addition, when the slide bar 63 moves to one side, the first telescopic plate 65 and the second telescopic plate 67 on the same side of the slide bar 63 are driven to contract, and the first telescopic plate 65 and the second telescopic plate 67 on the opposite side are driven to extend, ensuring that the slide groove 62 and the through groove 66 are always in a closed state to prevent liquid from flowing out.

[0039] like Figure 13 As shown, the regulating valve 64 is configured as a conical structure to better regulate the flow of the cold liquid.

[0040] like Figure 13 and Figure 14As shown, mercury is provided in the cylinder 69, and the temperature difference between the hot liquid in the first water outlet pipe 52 and the second water outlet pipe 53 is reduced by the principle of mercury absorbing heat and expanding, thereby ensuring that the temperature difference on both sides of the battery module 7 is reduced and heat is evenly dissipated.

[0041] Working process

[0042] When the battery module 7 is to be cooled, the first water pump 35 injects the cold liquid in the first cooling box 32 into the first water inlet pipe 31 and the first cooling pipe 36 through the first water supply pipe 33, and flows from the first U-shaped pipe 37 through the first connecting pipe 38 into the first cooling pipes 36 below to dissipate heat for the battery module 7. After the cold liquid absorbs heat, its temperature increases. Then, the hot liquid passes through the first exchange pipe 54 to reach the constant temperature pipe 51, and flows from the first water outlet pipe 52 and the second connecting pipe 39 into the first U-shaped pipe 37 and the first return pipe 34 on the other side and the first cooling box 32 for cooling and circulation. At the same time, the second water pump 45 injects the cold liquid in the second cooling box 42 into the second water inlet pipe 41 and the second cooling pipe 46 through the second water supply pipe 43, and flows from the second U-shaped pipe 47 through the third connecting pipe 48 into the second cooling pipes 46 below to dissipate heat for the battery module 7. After the cold liquid absorbs heat, its temperature increases. Then, the hot liquid passes through the second exchange pipe 55 to reach the constant temperature pipe 51, and flows from the second water outlet pipe 53 and the fourth connecting pipe 39 into the second cooling pipe 46. The liquid flows from the tube 49 into the second U-shaped tube 47, the second return pipe 44, and the second cooling box 42 on the other side, where it is cooled and then circulated for heat dissipation. Since the thermostatic tube 51 has a second water inlet pipe 41, the cold liquid flowing out of the second water inlet pipe 41 can exchange heat with the hot liquid in the first water outlet pipe 52. This method can reduce the temperature difference between the two sides of the battery module 7. When the temperature of the hot liquid in the first water outlet pipe 52 and the second water outlet pipe 53 differs, the mercury in the regulating tube 61 and the cylinder 69 on the side with the higher temperature expands more, thereby pushing the piston 70, the piston rod 71, the connecting rod 72, the sliding rod 63 and the regulating valve 64 to move to the side away from the cylinder 69. Here, the conical head of the regulating valve 64 is away from the inlet of the cold liquid, so that the water flow of the cold liquid is larger, thereby performing heat exchange with the hot liquid. At the same time, the conical head of the regulating valve 64 on the other side is pushed closer to the inlet of the cold liquid, so that the water flow of the cold liquid is reduced, thereby balancing the temperatures on both sides, making the temperatures on both sides consistent, and ensuring uniform cooling and heat dissipation of the battery module 7.
