Description

Technical Field

[0001] This utility model relates to the field of cooling water filtration technology, and more specifically to a filter suitable for data center cooling water systems. Background Technology

[0002] Driven by technologies and businesses such as artificial intelligence, big data, machine learning, high-definition video, AR, and VR, the demand for data center construction will continue to accelerate. Energy conservation, emission reduction, and strict PUE control are becoming increasingly important, with data centers focusing on energy saving (PUE) and carbon saving (CUE) throughout their entire lifecycle. Currently, data center air conditioning primarily uses water cooling. As data center heat dissipation designs increase, air conditioning pipe diameters also grow. Given the limited space in cooling rooms, pipe arrangement is becoming increasingly congested. Water treatment filters, as indispensable components of air conditioning systems, need structural adjustments to reduce installation space while maintaining functionality, and to optimize installation. How to further reduce the installation space of filtration systems is a pressing technical problem that needs to be solved. Utility Model Content

[0003] This invention addresses the aforementioned technical problems by proposing a filter suitable for data center cooling water systems.

[0004] The technical means adopted in this utility model are as follows:

[0005] A filter suitable for data center cooling water systems includes a filter tank, an inlet pipe, an outlet pipe, and a drain pipe. The inlet pipe, the outlet pipe, and the drain pipe are all connected to the filter tank. The drain pipe is connected to the bottom of the filter tank. The filter tank also has a turbulence device connected to the output end of the inlet pipe. The inlet pipe is a straight pipe, with its upper end located on the outer side of the top of the filter tank to form an inlet pipe interface. The lower end of the inlet pipe passes through the outlet chamber inside the filter tank and enters the turbulence chamber at the bottom of the filter tank, where it connects to the turbulence device.

[0006] Furthermore, the filter tank is equipped with a water distributor, which divides the filter tank into an outlet chamber and a turbulent flow chamber.

[0007] The water distributor includes a water distributor base plate and multiple water diffusers. The multiple water diffusers are evenly distributed on the water distributor base plate located on one side of the turbulent flow cavity. Each water diffuser is a frustum conical structure with its larger end fixedly connected to the water distributor base plate. The water distributor base plate and the water diffusers are provided with water distribution through holes that connect the turbulent flow cavity and the water outlet cavity.

[0008] Furthermore, the water distribution through-hole is a tapered hole with an inner diameter that gradually increases from the turbulence cavity side to the water outlet cavity side.

[0009] Furthermore, the turbulence device includes a first guide section and a second guide section;

[0010] The first guide section is a cylindrical structure, the upper end of the first guide section is connected to the lower end of the water inlet pipe, and a plurality of first water outlet holes are evenly distributed on the side wall of the first guide section.

[0011] The lower end of the first guide section is connected to the second guide section. The second guide section is a conical structure with a diameter that gradually increases from one end connected to the first guide section to the other end. The other end of the second guide section is an arc-shaped closed end. Multiple second water outlet holes are evenly distributed on the side wall of the second guide section.

[0012] Furthermore, the bottom of the filter tank is also provided with an adjustable support leg. The adjustable support leg includes a first support rod fixedly connected to the bottom of the filter tank and a second support rod connected to the lower end of the first support rod. The first support rod and the second support rod are threaded together. The second support rod is provided with a turning part for turning the second support rod.

[0017] Furthermore, the top of the filter tank is also provided with an exhaust pipe interface.

[0018] Compared with the prior art, the filter for data center cooling water systems disclosed in this utility model has the following advantages: Since the inlet pipe of the filter for data center cooling water systems disclosed in this application is a straight pipe and the upper end of the inlet pipe is set on the outer side of the top of the filter tank to form an inlet pipe interface, the inlet pump can be directly set above the filter and connected to the inlet pipe, reducing the number of connecting pipes and thus effectively reducing the volume and installation space of the filtration system.

[0025] like Figure 1 As shown, the present invention discloses a filter for a data center cooling water system, comprising a filter tank 1, an inlet pipe 10, an outlet pipe, and a drain pipe 12. The inlet pipe 10, the outlet pipe, and the drain pipe 12 are all connected to the filter tank 1. The drain pipe 12 is connected to the bottom of the filter tank 1. The filter tank 1 is also provided with a turbulence device 2 connected to the output end of the inlet pipe 10. The inlet pipe 10 is a straight pipe. The upper end of the inlet pipe 10 is located on the outer side of the top of the filter tank 1 to form an inlet pipe interface 13. The lower end of the inlet pipe 10 passes through the outlet cavity 14 inside the filter tank 1 and enters the turbulence cavity 15 at the bottom of the filter tank 1, and is connected to the turbulence device 2.

[0026] Specifically, such as Figure 5 The diagram shows the structure of an existing filtration system filter, including a filter tank 1, an inlet pipe 10, an outlet pipe, and a drain pipe 12. The inlet pipe 1 of the filter tank 1 is a bend. Both the inlet pipe interface 13 and the outlet pipe interface 11 are located on the side of the filter tank. When this filtration system is connected to a data center cooling system, the data center cooling system's drain pipe needs to be connected to the inlet pipe interface via a bend or similar structure. This not only complicates the structure but also results in a large volume and requires significant installation space. Figure 1As shown, the filter disclosed in this application for data center cooling water systems has an inlet pipe 10 that is a straight pipe. The upper end of the inlet pipe 10 is located on the outer side of the top of the filter tank 1 to form an inlet pipe interface 13. The lower end of the inlet pipe 10 passes through the outlet chamber 14 inside the filter tank and enters the turbulence chamber 15 at the bottom of the filter tank 1, where it is connected to the turbulence device. This allows the drain pipe of the data center cooling system to be directly connected to the inlet pipe interface at the top of the filter tank, thus eliminating the need for bends and other connecting structures. At the same time, it allows the filter tank to be directly installed below the drain pipe of the data center cooling system, which not only simplifies the installation structure but also reduces the installation space.

[0027] Furthermore, the filter tank 1 is provided with a water distributor 3, which divides the filter tank 1 into an outlet chamber 14 and a turbulent flow chamber 15.

[0028] The water distributor 3 includes a water distributor base plate 30 and a plurality of water diffusers 31. The plurality of water diffusers 31 are evenly distributed on the water distributor base plate 30 on one side of the turbulent flow cavity 15. Each water diffuser 31 is a frustum conical structure with its larger end fixedly connected to the water distributor base plate 30. The water distributor base plate 30 and the water diffusers 31 are provided with water distribution through holes 32 that connect the turbulent flow cavity 15 and the water outlet cavity 14.

[0029] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, a water distributor 3 is provided inside the filter tank 1. The water distributor 3 can be fixed inside the filter tank 1 by welding or other means. The water distributor 3 divides the filter tank 1 into an outlet chamber 14 and a turbulent flow chamber 15. The water distributor 3 includes a water distributor base plate 30 and multiple water diffusers 31. The multiple water diffusers 31 are evenly distributed on one side of the water distributor base plate 30 located in the turbulent flow chamber 15. The water diffuser 31 is a frustum conical structure with its larger end fixedly connected to the water distributor base plate 30. The water distributor base plate 30 and the water diffusers 31 are provided with water distribution through holes 32 that connect the turbulent flow chamber 15 and the outlet chamber 14. In this embodiment, due to the provision of the water distributor 3, the cooling water in the turbulent flow chamber 15 can slowly enter the outlet chamber 14 through the water distributor, making the water flow in the outlet chamber 14 more stable, which is beneficial to the stable operation of the water pump connected to the filter tank and more energy-efficient. Meanwhile, since the water distributor base plate 30 is provided with a water diffuser 31, which is a truncated cone structure, the cooling water in the upper part of the turbulent flow chamber 15 can collide with the outer wall of the water diffuser 31 during the rising process, thereby reducing the water flow speed (the movement speed of the small particles). The reduction in the speed of the small particles accelerates their natural sedimentation, which is beneficial to improving the filtration effect of the filter tank.

[0030] Furthermore, the water distribution through-hole is a tapered hole with an inner diameter that gradually increases from the turbulence cavity side to the water outlet cavity side.

[0031] Specifically, in this embodiment, such as Figure 3 As shown, the water distribution hole 32 is a conical hole, which makes the outlet area of ​​the cooling water in the upper part of the turbulent flow chamber 15 gradually increase as it enters the outlet chamber through the water distribution hole 32. This makes the water flow more stable when the cooling water enters the outlet chamber, which is conducive to further improving the stable operation of the water pump connected to the filter tank and making it more energy-efficient.

[0032] Furthermore, the turbulence device 2 includes a first guide section 20 and a second guide section 21;

[0033] The first guide section 20 has a cylindrical structure. The upper end of the first guide section 20 is connected to the lower end of the water inlet pipe 10. A plurality of first water outlet holes 22 are evenly distributed on the side wall of the first guide section 20.

[0034] The lower end of the first guide section 20 is connected to the second guide section 21. The second guide section 21 is a conical cylinder structure with a diameter that gradually increases from one end connected to the first guide section 20 to the other end. The other end of the second guide section 21 is an arc-shaped closed end. Multiple second water outlet holes 23 are evenly distributed on the side wall of the second guide section 21.

[0035] Specifically, such as Figure 1 As shown, in this embodiment, the turbulence device 2 includes a first guide section 20 with a cylindrical structure (uniform outer diameter) and a second guide section 21 with a conical structure (outer diameter gradually increases from one end connected to the first guide section to the other end). The first guide section 20 and the second guide section 21 are respectively provided with a first water outlet 22 and a second water outlet 23. The lower end of the second guide section 21 is an arc-shaped closed end. The upper end of the first guide section 20 is connected to the lower end of the inlet pipe 10 by welding or threaded connection. After the cooling water to be filtered enters the turbulence device 2 through the inlet pipe 10, a portion is injected into the turbulence chamber 15 through the first water outlet 22 on the first guide section 20, and a portion is injected into the turbulence chamber 15 through the second water outlet 23 on the second guide section 21. The flow direction of the cooling water injected into the turbulence chamber 15 through the first water outlet 22 is horizontal. Figure 1 As indicated by arrow A in the middle, the cooling water injected into the turbulent flow chamber 15 through the second water outlet 23 flows at a certain angle to the horizontal direction. Figure 1As indicated by arrow B in the middle, the cooling water flow injected into the turbulent flow chamber 15 through the second water outlet 23 converges with the cooling water flow injected into the turbulent flow chamber 15 through the first water outlet, thereby forming a turbulent region 150 in the upper part of the turbulent flow chamber 15. The turbulence accelerates the deposition rate of impurities such as particulate matter or willow catkins in the cooling water. At the same time, the lower end of the second guide section 21 is an arc-shaped closed end, thereby forming a stable region 151 in the lower part of the second guide section 21. This allows impurities such as particulate matter or willow catkins to be effectively deposited at the bottom of the filter tank 1 without being disturbed by the water flow injected into the inlet pipe. This turbulence device can effectively improve the filtration effect and filtration speed of the filter tank.

[0036] Furthermore, the bottom of the filter tank 1 is also provided with an adjustable support leg 4. The adjustable support leg 4 includes a first support rod 40 fixedly connected to the bottom of the filter tank 1 and a second support rod 41 connected to the lower end of the first support rod 40. The first support rod 40 and the second support rod 41 are threadedly connected. The second support rod 41 is provided with a turning part 42 for turning the second support rod 41. The second support rod 41 is also provided with a locking nut 43 for locking the positions of the first support rod 40 and the second support rod 41.

[0037] Specifically, such as Figure 4 As shown, in this embodiment, the bottom of the filter tank 1 is fixed with multiple first support rods 40 by welding or other means. The lower end of the first support rod 40 is provided with a threaded hole arranged in the axial direction. The upper end of the second support rod 41 is machined with external threads. The second support rod 41 can be threadedly connected to the first support rod 40. By adjusting the length of the threaded connection between the first support rod 40 and the second support rod 41, the height of the filter tank 1 can be adjusted, thereby realizing the support and height adjustment of the filter tank 1, so as to facilitate the connection between the filter tank 1 and other components. In this embodiment, the lower end of the second support rod 41 is provided with a foot. The diameter of the foot is larger than the diameter of the support leg, so as to increase the contact area with the ground and thus improve the stability of the support. The second support rod 41 is also provided with a turning part 42. The turning part 42 can be a polygonal structure machined on the second support rod 41 or a welded nut, so as to facilitate clamping and turning it with tools such as wrenches. The second support rod 41, with its externally threaded portion, is also equipped with a locking nut 43. After the first support rod 40 and the second support rod 41 are connected and the support length is adjusted, rotating the locking nut 43 causes it to abut against the end of the first support rod 40, thereby preventing the connection between the first and second support rods from loosening and ensuring stable support for the filter tank. In this embodiment, the support legs are adjustable, allowing for direct ground installation and facilitating on-site implementation.

[0038] Furthermore, a drain valve 120 is provided on the drain pipe 12.

[0039] Specifically, in this embodiment, the drain pipe 12 is located at the bottom of the filter tank 1 so that impurities such as willow catkins or particulate matter deposited in the filter tank 1 can be discharged through the drain pipe 12. At the same time, a drain valve 120 is provided on the drain pipe 12 so that the drain pipe can be easily controlled. The drain valve can close the drain pipe during sedimentation filtration, and open the drain valve when sewage needs to be discharged so that the deposited impurities can be discharged through the drain pipe.

[0040] Furthermore, a cleaning pipe interface 16 is provided on the filter tank 1 at the position corresponding to the turbulence cavity 15.

[0041] Specifically, in this embodiment, a cleaning pipe interface 16 is provided at the lower part of the filter tank 1, corresponding to the turbulence chamber 15, to facilitate connection with a cleaning pipe. The inner side of the cleaning pipe interface 16 is opposite to the turbulence device 2. Clean water can be injected into the filter tank 1 through the cleaning pipe interface 16, and the injected clean water can be effectively sprayed onto the turbulence device 2 and the water distributor base plate 30 to flush the water outlet of the turbulence device 2 and the water distributor, thereby ensuring the effectiveness of the filter tank during normal filtration. There can be one or more cleaning pipe interfaces 16. Preferably, there are two cleaning pipe interfaces, which are symmetrically arranged on the filter tank 1 to effectively flush the inside of the filter tank 1.

[0042] Furthermore, the top of the filter tank 1 is also provided with a hoisting component 17.

[0043] Specifically, in this embodiment, the upper part of the filter tank 1 is provided with multiple lifting lugs, generally 2-4 in number. The lifting lugs can be fixed to the top of the filter tank 1 by welding or other methods, so as to facilitate lifting or installation by lifting devices such as hooks.

[0044] Furthermore, a pressure sensor 18 is also provided on the filter tank 1.

[0045] Specifically, multiple pressure sensors 18 are provided on the inner wall of the filter tank 1 along its height direction. The pressure sensors can detect the pressure inside the filter tank in real time, so as to transmit the obtained pressure to the controller. The controller controls the opening and closing of the valves on the inlet and outlet pipes to control the speed of water inflow and outflow, thereby effectively ensuring the filtration effect.

[0046] Furthermore, the top of the filter tank 1 is also provided with an exhaust pipe interface 19.

[0047] Specifically, an exhaust pipe interface is provided at the top of the filter tank 1. The exhaust pipe interface is used to connect with the exhaust pipe. An exhaust valve can also be installed on the exhaust pipe. By setting the exhaust pipe interface 19 to connect to the exhaust pipe, the gas in the filter tank can be effectively discharged, thereby maintaining the pressure in the filter tank, so that the filtered cooling water can be effectively discharged from the outlet pipe.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
