Description

Technical Field

[0001] The utility model belongs to the technical field of energy storage, and in particular relates to a pipeline arrangement structure of a battery cooling system in an energy storage project. Background Art

[0002] Battery cooling systems are a critical component of energy storage projects. Batteries generate heat during charging and discharging. Failure to dissipate this heat promptly and effectively can lead to reduced battery performance, shortened lifespan, and even safety hazards. Traditional battery cooling systems primarily remove heat generated by the batteries by circulating coolant through pipes. However, existing pipe layouts present several issues.

[0003] First, the design and layout of pipelines often fail to fully consider fluid dynamics, resulting in uneven coolant flow. Some batteries may not be effectively cooled due to insufficient coolant flow, affecting the efficiency and safety of the overall energy storage system. Second, improper pipeline layout can increase the difficulty of maintenance and repair. Once a pipeline becomes clogged or fails, the detection and repair process is complex and time-consuming. Furthermore, traditional cooling systems lack effective monitoring methods, making it impossible to monitor and adjust coolant flow and temperature in real time.

[0004] Therefore, a new battery cooling duct layout is urgently needed to address these issues in existing technologies and improve the stable operation and long-term reliability of energy storage systems. This new structure should provide more optimized coolant flow distribution to ensure that each battery cell receives sufficient and even cooling. Furthermore, it should facilitate monitoring and maintenance, allowing for quick identification and resolution of potential cooling system issues.

[0005] In response to the above problems, this utility model proposes a battery cooling pipe layout structure for energy storage projects, aiming to improve cooling efficiency by optimizing pipe design, while simplifying maintenance procedures and ensuring system reliability and safety. Utility Model Content

[0006] This utility model aims to solve the problems of low cooling efficiency and uneven cooling caused by the pipe layout in the existing energy storage project battery cooling system. To achieve the above purpose, this utility model adopts the following technical solutions:

[0007] A battery cooling pipe arrangement structure for an energy storage project includes a chiller. The chiller cools a refrigerant, which is then diverted to a secondary water inlet pipe through a ball valve and the primary pipes in each box. The refrigerant then passes through a tee connector to a tertiary water inlet pipe and the next section of the secondary water inlet pipe. The tertiary water inlet pipe then flows into a battery cooling plate to cool the battery. The water then flows out of the tertiary return pipe to the secondary return pipe, passes through a tee connector to the primary pipe, and then flows back to the chiller for further cooling. The structure is characterized in that a first flow regulating device is added to the secondary water inlet pipe, and a second flow regulating device is added to the tertiary water inlet pipe.

[0008] In the above energy storage project, by adding a first flow regulating device to the secondary water inlet pipeline and a second flow regulating device to the tertiary water inlet pipeline, when the refrigerant reaches the secondary water inlet pipeline through the primary pipeline, the first flow regulating device in the secondary water inlet pipeline adjusts the flow of the secondary water inlet pipeline to achieve uniform distribution, and then adding a second flow regulating device to the tertiary water inlet pipeline to achieve uniform distribution of the flow of the refrigerant in the tertiary water inlet pipeline, thereby achieving hydraulic balance and making the flow of the refrigerant through each battery cooling plate the same, thereby achieving consistent cooling effect, and preventing poor cooling effect of some batteries due to uneven distribution, thereby affecting battery operation.

[0009] Furthermore, the flow regulating device includes a flow meter and a regulating valve.

[0010] Furthermore, the battery cooling plates in the energy storage project are stacked vertically at intervals, one side of which is connected to the tertiary water inlet pipeline, and the other side is connected to the tertiary return water pipeline. The secondary water inlet pipeline is located on the side close to the tertiary water inlet pipeline and is connected to the tertiary water inlet pipeline, and the secondary return water pipeline is located on the side close to the tertiary return water pipeline and is connected to the tertiary return water pipeline.

[0011] Furthermore, in the data center project, the data center is stacked vertically at intervals, one side of which is connected to a tertiary water inlet pipeline, and the same side is also connected to a tertiary return pipeline, the secondary water inlet pipeline and the secondary return pipeline are arranged side by side on the same side, the tertiary water inlet pipeline and the secondary water inlet pipeline are connected, and the tertiary return pipeline and the secondary return pipeline are connected.

[0012] Furthermore, an inlet exhaust valve and a return exhaust valve are respectively provided at the top of the secondary water inlet pipeline and the top of the secondary water return pipeline.

[0013] Furthermore, the flow control device has the dual functions of displaying and regulating flow. This device can display the flow rate of the fluid in real time and adjust the flow rate as needed. It can be an electric flow control valve that can adjust the flow rate through an electronic control system and is equipped with a sensor or display to display flow data in real time.

[0014] In the data center project, by adding a second flow meter to the tertiary water inlet pipeline, the refrigerant reaches the secondary water inlet pipeline through the primary pipeline and is then distributed to the tertiary water inlet pipeline. The second flow meter can then be observed to determine whether there is refrigerant passing through the pipeline. When the pipeline is blocked, maintenance personnel can quickly determine which pipeline is blocked through the flow meter and repair it in time.

[0015] Compared with the existing technology, the technical solution adopted by this utility model has the following key advantages:

[0016] Current energy storage projects only have corresponding pipelines, but no flow meters to control the flow in the pipelines. It is impossible to understand the flow conditions of each pipeline. The flow in the tertiary pipelines may not be evenly distributed, and the condensate flow of some batteries is too small, which will lead to insufficient cooling effect for these batteries and affect battery operation.

[0017] Current data center projects also only have pipelines, and there is no way to determine whether the refrigerant flow in the pipeline is normal, no real-time detection is possible, and no quick judgment can be made when a blockage occurs. The battery cooling pipeline layout structure for energy storage projects provided by the present invention can effectively achieve precise control and real-time monitoring of the coolant flow by adding flow regulating devices to the secondary and tertiary pipelines. Such a design optimizes the efficiency of the cooling system, ensures that each unit of the battery pack is evenly cooled, and thus improves the working performance and life of the battery. At the same time, in data center projects, the setting of the flow meter also helps to quickly discover and solve refrigerant flow problems, improve system stability and ease of maintenance, and thus enhance the reliability and efficiency of the entire system.

[0021] The technical solution of the present utility model is further explained below with reference to the accompanying drawings.

[0022] A battery cooling pipe arrangement structure for an energy storage project includes a chiller, which cools the refrigerant. The refrigerant is then diverted to the secondary water inlet pipe 9 through a ball valve 4 and the primary pipe 3 in each box, and then diverted to the tertiary water inlet pipe 8 and the next section of the secondary water inlet pipe 9 through a three-way connector. The tertiary water inlet pipe 8 then flows into the battery cooling plate 14 to cool the battery, and then flows out of the tertiary return pipe 11 to the secondary return pipe 13, through the three-way connector to the primary pipe 3, and then flows back to the chiller for further cooling. The characteristic of the structure is that a first flow regulating device 5 is added to the secondary water inlet pipe 9, and a second flow regulating device 7 is added to the tertiary water inlet pipe 8.

[0023] In the above energy storage project, by adding a first flow regulating device 5 to the secondary water inlet pipeline 9 and a second flow regulating device 7 to the tertiary water inlet pipeline 8, when the refrigerant reaches the secondary water inlet pipeline 9 through the primary pipeline 3, the first flow regulating device 5 in the secondary water inlet pipeline 9 adjusts the flow rate in the secondary water inlet pipeline 9 to achieve uniform distribution. Then, by adding the second flow regulating device 7 to the tertiary water inlet pipeline 8, the flow rate of the refrigerant in the tertiary water inlet pipeline 8 is evenly distributed, achieving hydraulic balance and ensuring that the flow rate of the refrigerant through each battery cooling plate is the same, thereby achieving a consistent cooling effect and preventing uneven distribution from causing poor cooling effect on some batteries, thereby affecting battery operation. The flow regulating device includes a flow meter and a regulating valve.

[0024] In the energy storage project, the battery cooling plates 14 are stacked vertically at intervals, one side of which is connected to the tertiary water inlet pipeline 8, and the other side is connected to the tertiary return water pipeline 11. The secondary water inlet pipeline 9 is located on the side close to the tertiary water inlet pipeline 8 and is connected to the tertiary water inlet pipeline 8, and the secondary return water pipeline 13 is located on the side close to the tertiary return water pipeline 11 and is connected to the tertiary return water pipeline 11.

[0025] In the data center project, the data center 22 is stacked vertically at intervals, one side of which is connected to the tertiary water inlet pipeline 8, and the same side is also connected to the tertiary return water pipeline 11. The secondary water inlet pipeline 9 and the secondary return water pipeline 13 are arranged side by side on the same side, the tertiary water inlet pipeline 8 and the secondary water inlet pipeline 9 are connected, and the tertiary return water pipeline 11 and the secondary return water pipeline 13 are connected.

[0026] The top ends of the secondary water inlet pipe 9 and the secondary water return pipe 13 are provided with a water inlet exhaust valve 10 and a water return exhaust valve 12 respectively.

[0027] The flow control device has the dual functions of displaying and regulating flow. This device can display the fluid flow rate in real time and adjust the flow rate as needed. It can be an electric flow control valve that adjusts the flow rate through an electronic control system and is equipped with a sensor or display to display flow data in real time.

[0028] In data center projects, by adding a second flow meter 24 to the tertiary water inlet pipeline 8, refrigerant flows through the primary pipeline to the secondary water inlet pipeline 9 and then to the tertiary water inlet pipeline 8. The second flow meter 24 can then be used to determine whether refrigerant is flowing through the pipeline. If a pipeline is clogged, maintenance personnel can quickly determine which pipeline is blocked using the flow meter and conduct timely repairs. The figure shows the refrigerant return pipeline 21 and the refrigerant inlet pipeline 20.
