Description

Technical Field

[0001] The utility model relates to the technical field of flow regulation, and particularly relates to a flow control component and an energy storage container system. Background Art

[0002] An energy storage container system is usually equipped with facilities such as an inverter, a battery pack management system, a power distribution cabinet, an air conditioner or an access control. According to different usage scenarios, it can select energy storage strategies on the user side or the power generation side to achieve functions such as peak shaving and valley filling, and power smoothing to improve the drastic fluctuations of the power grid load. At present, the energy storage container system has the characteristics of large capacity and high voltage. However, the internal battery modules have certain safety risks. Especially during high-rate charging and discharging, the battery modules themselves are prone to generate more heat. If the heat generated during the operation of the battery modules cannot be taken away in time, it will cause the battery temperature to continue to rise, and then there may be a potential risk of thermal runaway and further fire and explosion.

[0003] At present, water cooling is commonly used to cool down lithium batteries. However, the flow regulation of the energy storage container system is achieved by adjusting the inner diameter of a tee or by using a switch ball valve to adjust the flow rate of the tee branch. Although using a switch ball valve is very convenient, it cannot quantitatively control the flow rate, and at the same time, it will increase the production cost of the energy storage container system. Although the method of changing the inner diameter of the tee can be quantitative, it will increase the types of valves and the mold opening cost. Therefore, the above methods increase the cost of flow regulation. Summary of the Utility Model

[0004] Embodiments of the utility model provide a flow control component and an energy storage container system, which can improve the technical problem of high cost in flow regulation in related technologies.

[0005] In a first aspect, embodiments of the utility model provide a flow control component, which includes: a valve body having a main flow channel and a branch flow channel communicating with the main flow channel; a flow limiting member disposed in the main flow channel and / or the branch flow channel, the flow limiting member having a flow limiting hole, the aperture of the flow limiting hole being smaller than the inner diameter of the main flow channel and / or the branch flow channel, and the flow limiting hole communicating with the main flow channel and / or the branch flow channel to limit the flow rate in the main flow channel and / or the branch flow channel.

[0006] In one embodiment, the radial cross-sections of the flow limiting member, the main flow channel and the branch flow channel are all circular. The outer diameter of the flow limiting member is R1, the inner diameter of the main flow channel is R2, and the inner diameter of the branch flow channel is R3, where R3≤R2<R1.

[0007] In one embodiment, 0.05mm≤R1 - R2≤0.1mm.

[0008] In one embodiment, 0.05mm≤R1 - R3≤0.1mm.

[0009] In one embodiment, the flow-limiting member includes a first flow-limiting cylinder and a second flow-limiting cylinder.

The inner diameter of the main flow channel is greater than that of the branch flow channel, and the outer diameter of the first flow-limiting cylinder is greater than that of the second flow-limiting cylinder.

[0010] In one embodiment, the flow-limiting hole includes a variable-diameter structure.

[0011] In one embodiment, the axis of the flow-limiting hole is parallel to the axis of the main flow channel and / or the branch flow channel.

[0012] In one embodiment, the material of the flow-limiting member includes aluminum.

At the same time, a flow-limiting member is disposed in the main flow channel and / or the branch flow channel, and the flow-limiting hole is connected to the main flow channel and / or the branch flow channel. When the fluid flows through the main flow channel and the branch flow channel, the flow-limiting hole of the flow-limiting member can limit the flow rate of the fluid in the main flow channel and / or the branch flow channel. Therefore, by setting flow-limiting members with different-sized flow-limiting holes in the main flow channel and / or the branch flow channel of different valve bodies, quantitative control of the flow rate in the main flow channel and / or the branch flow channel of different valve bodies can be achieved without changing the size of the valve body. Compared with the related technical solutions, not only can quantitative control of the flow rate be realized, but also no additional mold opening cost is required. Therefore, the cost of flow rate adjustment will not increase, which is beneficial to reducing the use cost of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of the present utility model.

[0029] As Figures 1 - 5 shown, in the first aspect, an embodiment of the present utility model provides a flow control assembly 1, and the flow control assembly 1 includes: a valve body 10 having a main flow channel 11 and a branch flow channel 12 communicating with the main flow channel 11; a flow limiting member 20 disposed in the main flow channel 11 and / or the branch flow channel 12, the flow limiting member 20 having a flow limiting hole 21, the aperture of the flow limiting hole 21 being smaller than the inner diameter of the main flow channel 11 and / or the branch flow channel 12, and the flow limiting hole 21 communicating with the main flow channel 11 and / or the branch flow channel 12 to limit the flow rate in the main flow channel 11 and / or the branch flow channel 12.

[0030] Applying the technical solution of the present utility model, the valve body 10 includes a main flow channel 11 and a branch flow channel 12 communicating with the main flow channel 11. At the same time, a flow limiting member 20 is arranged in the main flow channel 11 and / or the branch flow channel 12, and a flow limiting hole 21 communicates with the main flow channel 11 and / or the branch flow channel 12. When the fluid flows through the main flow channel 11 and the branch flow channel 12, the flow limiting hole 21 of the flow limiting member 20 can limit the flow rate of the fluid in the main flow channel 11 and / or the branch flow channel 12. Therefore, by arranging flow limiting members 20 with different-sized flow limiting holes 21 in the main flow channel 11 and / or the branch flow channel 12 of different valve bodies 10, quantitative control of the flow rate in the main flow channel 11 and / or the branch flow channel 12 of different valve bodies 10 can be achieved without changing the size of the valve body 10. Compared with the related technical solutions, not only can quantitative control of the flow rate be realized, but also no additional mold opening cost is required. Therefore, the cost of flow rate adjustment will not increase, which is beneficial to reducing the use cost of the device.

[0031] In this application, the valve body 10 is made of PE material, that is, polyethylene. Since the PE material has good chemical stability, it can remain stable in a variety of chemical substance environments and is not easily corroded and damaged. This characteristic makes it widely used in the production process. Specifically, the PE material can resist the erosion of most acids, alkalis, organic solutions, and hot water, but it should be noted that it is not resistant to specific chemicals such as oxidizing acids (such as concentrated nitric acid). The PE material also exhibits good corrosion resistance and can withstand the erosion of a variety of chemical substances. Therefore, it can extend the service life of the flow control component 1 and further reduce the use cost of the flow control component 1.

[0032] Furthermore, the PE material is easy to process and can be conveniently cut, drilled, bent, welded, bonded, etc., and the processing cost is relatively low. This characteristic makes it widely used in various processing and manufacturing industries, greatly simplifying the processing process and reducing the production cost. At the same time, the PE material is relatively light, but it has high strength and stiffness and can withstand large pressures and bending stresses. This characteristic makes the PE material perform well in application scenarios that need to bear a certain load. Moreover, the PE material is an excellent insulating material with good electrical insulation and dielectric properties. Therefore, it can ensure the use stability of the flow control component 1.

[0033] Specifically, the PE material is an environmentally friendly and non-toxic material and will not cause harm to human health and the environment. Therefore, the safety and hygiene of the flow control component 1 can be ensured. And the PE material also has good low-temperature performance and impact resistance and can maintain good toughness and impact resistance in low-temperature environments, thereby further extending the service life of the flow control component 1.

[0034] In one embodiment, the radial cross-sections of the flow limiter 20, the main flow channel 11, and the branch flow channel 12 are all circular. The outer diameter of the flow limiter 20 is R1, the inner diameter of the main flow channel 11 is R2, and the inner diameter of the branch flow channel 12 is R3, where R3 ≤ R2 < R1. By setting the above structure, the inner diameter of the main flow channel 11 is set to be greater than or equal to the inner diameter of the branch flow channel 12, so that the flow rate of the main flow channel 11 can be ensured to be greater than or equal to the flow rate of the branch flow channel 12. When the inner diameter of the main flow channel 11 is larger, the flow resistance of the fluid in the main flow channel 11 is relatively small. This helps the fluid to flow more smoothly, reduces energy loss, and improves the overall efficiency of the system. At the same time, the larger inner diameter of the main flow channel 11 can make the velocity distribution of the fluid more uniform before entering the branch flow channel 12, avoiding excessive velocity gradients or vortices at the branch inlet, thereby improving the flow state of the fluid. Due to the larger inner diameter of the main flow channel 11, the flow of the fluid in the main flow channel 11 is more stable and not easily affected by external disturbances, which helps to ensure the stable operation of the entire fluid system. And the design of the inner diameter of the main flow channel 11 being larger than the inner diameter of the branch flow channel 12 can also make the distribution of the fluid in the system more reasonable, avoiding excessive pressure drop or uneven flow distribution in the branch flow channel 12.

[0035] And the outer diameter of the flow limiter 20 is set to be greater than the inner diameter of the main flow channel 11 and the inner diameter of the branch flow channel 12, so that the flow limiter 20 and the main flow channel 11 and / or the branch flow channel 12 are in an interference fit, which can avoid the problem that the flow limiter 20 is washed away by the fluid during the use of the flow control assembly 1, thereby ensuring the stability of the flow control assembly 1 during use.

[0036] In one embodiment, 0.05 mm ≤ R1 - R2 ≤ 0.1 mm. When R1 - R2 > 0.1 mm, the difference between the outer diameter of the current-limiting member 20 and the inner diameter of the main flow channel 11 is too large. After the current-limiting member 20 and the main flow channel 11 are assembled, the degree of fit between the two is too high. Since the material of the main flow channel 11 is PE, it is easy to damage the inner wall structure of the main flow channel 11, thereby reducing the service life of the valve body 10. When R1 - R2 < 0.05 mm, the difference between the outer diameter of the current-limiting member 20 and the inner diameter of the main flow channel 11 is too small. After the current-limiting member 20 and the main flow channel 11 are assembled, the current-limiting member 20 and the main flow channel 11 are assembled loosely. After long-term use, the current-limiting member 20 may be washed away by the fluid, thereby reducing the stability of the valve body 10 during use. Therefore, setting 0.05 mm ≤ R1 - R2 ≤ 0.1 mm can not only ensure the degree of fit between the two, is not easy to damage the inner wall structure of the main flow channel 11, thereby improving the service life of the valve body 10, but also will not cause the current-limiting member 20 to be washed away by the fluid, thereby ensuring the stability of the valve body 10 during use. Optionally, R1 - R2 can be set to values such as 0.05 mm, 0.08 mm, or 0.1 mm. The specific setting should be selected according to the use environment of the valve body 10 and is not specifically limited here.

[0037] In one embodiment, 0.05 mm ≤ R1 - R3 ≤ 0.1 mm. When R1 - R3 > 0.1 mm, the difference between the outer diameter of the current-limiting member 20 and the inner diameter of the branch flow channel 12 is too large. After the current-limiting member 20 and the branch flow channel 12 are assembled, the degree of fit between the two is too high. Since the material of the branch flow channel 12 is PE, it is easy to damage the inner wall structure of the branch flow channel 12, thereby reducing the service life of the valve body 10. When R1 - R3 < 0.05 mm, the difference between the outer diameter of the current-limiting member 20 and the inner diameter of the branch flow channel 12 is too small. After the current-limiting member 20 and the branch flow channel 12 are assembled, the current-limiting member 20 and the branch flow channel 12 are assembled loosely. After long-term use, the current-limiting member 20 may be washed away by the fluid, thereby reducing the stability of the valve body 10 during use. Therefore, setting 0.05 mm ≤ R1 - R3 ≤ 0.1 mm can not only ensure the degree of fit between the two, is not easy to damage the inner wall structure of the branch flow channel 12, thereby improving the service life of the valve body 10, but also will not cause the current-limiting member 20 to be washed away by the fluid, thereby ensuring the stability of the valve body 10 during use. Optionally, R1 - R3 can be set to values such as 0.05 mm, 0.08 mm, or 0.1 mm. The specific setting should be selected according to the use environment of the valve body 10 and is not specifically limited here.

[0038] In one embodiment, the flow limiter 20 includes a first flow limiting cylinder and a second flow limiting cylinder. The first flow limiting cylinder is disposed within the main flow channel 11 and / or the second flow limiting cylinder is disposed within the branch flow channel 12. The inner diameter of the main flow channel 11 is greater than the inner diameter of the branch flow channel 12, and the outer diameter of the first flow limiting cylinder is greater than the outer diameter of the second flow limiting cylinder. By providing the above structure, the main flow channel 11 and / or the branch flow channel 12 can be provided with their respective corresponding flow limiters 20, thereby further improving the applicability of the flow control assembly 1. At the same time, the flow limiter 20 can be customized according to different flow requirements, thereby being able to improve the applicability and the applicable range of the flow control assembly 1 as much as possible.

[0039] In one embodiment, the flow limiting hole 21 includes a variable diameter structure. By means of the processing method of the variable diameter hole, the processing accuracy can be effectively improved, so that the size of the processed flow limiting hole 21 is more accurate. At the same time, the variable diameter structure can change the flow rate and pressure inside the flow limiting hole 21. By adjusting the size of the variable diameter structure, the flow rate can be repositioned, and the flow velocity of the fluid inside the flow limiting hole 21 can be changed, thereby facilitating the control of the pressure inside the flow limiting hole 21. This ability makes the flow control assembly 1 more flexible and capable of adapting to different working requirements. And the design of the variable diameter hole helps to improve the transmission efficiency of the flow limiting hole 21. By optimizing the size and shape of the hole, the resistance loss of the fluid in the flow limiting hole 21 can be reduced, making the flow rate more stable and the transmission efficiency higher. The processing process of the variable diameter hole can improve the integrity of the flow limiting hole 21 and reduce the energy consumption of the flow limiting hole 21. At the same time, by optimizing the fluid flow state inside the flow limiting hole 21, the noise level of the flow limiting hole 21 system can be reduced, and the working environment of the flow control assembly 1 can be improved.

[0040] In one embodiment, the axis of the flow limiting hole 21 is parallel to the axis of the main flow channel 11 and / or the branch flow channel 12. With such a setting, the fluid flow can be made more stable. In the present application, the axis of the flow limiting hole 21 coincides with the axis of the main flow channel 11 and / or the branch flow channel 12.

[0041] In one embodiment, the material of the flow limiter 20 includes aluminum. Since the density of aluminum is about 2.7 g / cm 3 , which is much lower than that of steel (about 7.83 g / cm 3 ) and copper (about 8.93 g / cm 3 ), aluminum products are light in weight and convenient for handling and installation. This characteristic is particularly important, which can significantly reduce the weight of the flow limiter 20 and improve the installation and handling efficiency of the flow limiter 20. At the same time, aluminum can be quickly oxidized in the air to form a dense aluminum oxide protective film, and this protective film can resist further corrosion by air, water and chemical substances. This naturally formed protective layer is transparent, colorless and pollution-free, endowing the flow limiter 20 with good corrosion resistance, thereby being able to further improve the service life of the flow limiter 20.

[0042] Furthermore, aluminum has good plasticity and ductility and is easy to be processed into various shapes and specifications by means of rolling, extrusion, stretching, casting, etc. This makes the production cost of the flow limiter 20 relatively low and can meet diverse design requirements.

[0043] Optionally, the material of the flow limiter 20 can also be selected as iron, cobalt, nickel alloy, etc., as long as it can meet the usage requirements of the flow limiter 20. The specific setting should be selected according to the usage environment of the device, so as to improve the applicability and scope of application of the flow limiter 20.

[0044] In this application, the aluminum flow limiter 20 is preheated and then inserted into the PE plastic pipe to complete the installation of the flow limiter 20.

[0045] In an embodiment, the valve body 10 includes a three-way structure or a four-way structure. Such a setting can improve the applicability and scope of application of the flow limiter 20 to meet the flow limiting function in different valve bodies 10, thereby improving the applicability and scope of application of the flow limiter 20.

[0046] In a second aspect, an embodiment of the present utility model provides an energy storage container system, which includes the above-mentioned flow control assembly 1; a liquid cooling plate 30; and a fluid pipeline 40, and the fluid pipeline 40 is used to connect the liquid cooling plate 30 with the flow control assembly 1.

[0047] Applying the technical solution of the present utility model, the valve body 10 includes a main flow channel 11 and a branch flow channel 12 connected to the main flow channel 11. At the same time, a flow limiter 20 is arranged in the main flow channel 11 and / or the branch flow channel 12, and a flow limiting hole 21 is connected to the main flow channel 11 and / or the branch flow channel 12. When the fluid flows through the main flow channel 11 and the branch flow channel 12, the flow limiting hole 21 of the flow limiter 20 can limit the flow rate of the fluid in the main flow channel 11 and / or the branch flow channel 12. Therefore, by arranging flow limiters 20 with different flow limiting holes 21 of different sizes in the main flow channel 11 and / or the branch flow channel 12 of different valve bodies 10, quantitative control of the flow rate in the main flow channel 11 and / or the branch flow channel 12 of different valve bodies 10 can be achieved without changing the size of the valve body 10. Compared with the related technical solutions, not only can quantitative control of the flow rate be realized, but also no additional mold opening cost is required. Therefore, the cost of flow regulation will not be increased, which is beneficial to reducing the usage cost of the device.
