Description

Technical Field

[0001] This utility model relates to the field of fluid processing, and in particular to a quick-install tubular fine filter for high-cleanliness filtration of liquid-cooled fluids. Background Technology

[0002] Liquid cooling is widely used in industries such as information technology and new energy. To ensure effective heat dissipation, protect critical components such as heat exchangers and connectors, and extend the service life of equipment and pipelines, filtration devices are needed to effectively remove particulate matter and impurities from the liquid. Traditional Y-type filters have a small effective flow area and high flow resistance when using high-mesh filters; T-type filters are easy to achieve high-precision filtration, but have drawbacks such as excessive space requirements. Therefore, there is an urgent need to develop a filter that occupies less space, is easy to install and maintain, and can effectively reduce flow resistance while ensuring filtration accuracy.

[0036] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0037] Example 1

[0038] like Figures 1-3As shown, this embodiment 1 provides a quick-connect tubular fine filter for high-cleanliness filtration of liquid-cooled fluids, comprising a first filter tube 100 and a second filter tube 200. A filter core 300 is detachably connected within the first filter tube 100, and the first filter tube 100 and the second filter tube 200 are coaxially slidably connected along their length to accommodate high-cleanliness filtration of different workspace sizes. Specifically:

[0039] The first filter tube 100 is a hollow cylinder with both ends open, and its inner and outer walls are of appropriate thickness; the area surrounded by its inner wall is its inner cavity; at the opening on one side of the first filter tube 100, it narrows inward toward the central axis to form a fluid outlet 101, and the fluid outlet 101 and its inner cavity are provided with an annular stepped surface, and the mounting base 500 is coaxially engaged in the fluid outlet 101 and placed at the annular stepped surface; the mounting base 500 is a hollow cylinder with both ends open, and its inner wall is provided with internal threads for engaging the filter core 300.

[0040] The filter core 300 includes a filter basket 302 and a filter screen 301 covering the outer peripheral surface of the filter basket 302.

[0041] The filter basket 302 is a cylinder with a hollow inner cavity and several filter holes on its circumference. The inner cavity of the filter basket 302 is the inner cavity of the filter element. One end of the filter basket 302 is provided with a circular filter element outlet 3021. In order to facilitate engagement with the mounting base 500, the outer circumference of the filter element outlet 3021 is provided with external threads. The other end of the filter basket 302 is provided with a circular filter basket baffle 3022. The end of the filter element 300 near the filter basket baffle 3022 passes through the mounting base 500 and is placed inside the first filter tube 100. The external thread of the filter element outlet 3021 engages with the internal thread of the mounting base 500, so that the mounting base 500 can be detachably placed inside the mounting base 500.

[0042] In addition, the mesh size and material of filter screen 301 can be selected according to the application scenario, and the thickness and mesh size of filter basket 302 can be designed according to the liquid flow rate and pressure loss without any special restrictions; the length of filter screen 301 and filter basket 302 can be adapted to different flow rates and filtration accuracy requirements. The larger the flow rate and the higher the filtration accuracy requirement, the longer the length of filter screen 301 and filter basket 302 will be.

[0043] Preferably, the filter cartridge outlet 3021 and the mounting base 500 are also provided with sealing rings to ensure their sealing function.

[0044] Furthermore, the outer peripheral surface of the first filter tube 100 includes a floating tube portion 102 and a fixed tube portion 103. The fluid outlet portion 101 is located at the end of the fixed tube portion 103. The outer diameter of the floating tube portion 102 is smaller than the outer diameter of the fixed tube portion 103, and the inner diameters of the two are the same.

[0045] The second filter tube 200 is a hollow cylinder with both ends open, and its inner and outer walls have an appropriate thickness; the area surrounded by its inner wall is its inner cavity; and the inner diameter of the second filter tube 200 is larger than the outer diameter of the floating tube part 102. On the inner wall of the second filter tube 200, two arc-shaped limiting grooves are provided at intervals, and a circular sealing ring 400 is engaged in each limiting groove.

[0046] The floating tube portion 102 of the first filter tube 100 is coaxially sleeved inside the second filter tube 200 along its length direction. Each sealing ring 400 is sealed on the outer surface of the floating tube portion 102, and the inner wall of the second filter tube 200 is tightly attached to the outer surface of the floating tube portion 102. At this time, the inner cavities of the first filter tube 100 and the second filter tube 200 are in communication.

[0047] In this embodiment 1, the sealing ring 400 can be made of EPDM, PTFE, FPM or silicone.

[0048] In addition, to facilitate quick connection and installation with upstream and downstream fluid pipelines, quick-connect clamps 700 are connected to the openings on the opposite sides of the first filter pipe body 100 and the second filter pipe body 200. Specifically, a quick-connect clamp 700 is connected to the opening on the fluid outlet 101 side of the first filter pipe body 100. The quick-connect clamp 700 on the first filter pipe body 100 is connected to the pipe clamp on the downstream fluid pipeline, and then the first filter pipe body 100, the quick-connect clamp 700, and the downstream fluid pipeline are clamped and sealed together by a heavy-duty clamp 701. Similarly, the quick-connect clamp 700 on the second filter pipe body 200 is connected to the pipe clamp on the upstream fluid pipeline, and then the second filter pipe body 200, the quick-connect clamp 700, and the upstream fluid pipeline are clamped and sealed together by a heavy-duty clamp 701. The quick-connect clamp 700 and the heavy-duty clamp 701 are existing technologies and will not be described in detail here.

[0049] Furthermore, to ensure a sealing effect, each quick-release chuck 700 is also equipped with a chuck sealing ring 702 between the pipe chucks.

[0050] Preferably, the fixed tube portion 103 on the first filter tube 100 is provided with a maintenance port 800, which communicates with the inner cavity of the first filter tube 100. An observation sight glass 801 can be installed at the maintenance port 800 to observe the filtration status. A drain valve 802 can also be installed at the maintenance port 800 to discharge the filter residue in the first filter tube 100 and the second filter tube 200. A sensor 803 can also be installed at the maintenance port 800 to monitor the fluid in the filter of this utility model.

[0051] The operation process of this embodiment 1 is as follows:

[0052] Based on the dimensions of the pre-working space, the first filter tube 100, which is fitted inside the second filter tube 200, is stretched or compressed so that the total length of the first filter tube 100 and the second filter tube 200 is compatible with the dimensions of the working space.

[0053] The fluid to be filtered flows into the inner cavity of the second filter tube 200 and the inner cavity of the first filter tube 100 through the upstream fluid pipe. After being filtered by the filter screen 301 and the filter basket 302, the fluid flows sequentially through the inner cavity of the filter element to the filter element outlet 3021 and the fluid outlet 101, and then flows into the downstream fluid pipe. Among them, the solid particles in the fluid to be filtered are deposited at the bottom of the inner cavity of the first filter tube 100 or the inner cavity of the second filter tube 200 under their own gravity, while the suspended matter in the fluid to be filtered is attached to the outer wall of the filter screen, thereby achieving high-cleanliness filtration.

[0054] Example 2

[0055] like Figures 4-5 As shown, the difference between Embodiment 2 and Embodiment 1 is that a protective cap 600 is attached to the filter basket baffle 3022 of the filter core 300 within the inner cavity of the first filter tube 100. The protective cap 600 has an inner cavity with its opening facing the filter basket baffle 3022. Several fluid gaps are provided on the circumferential surface of the inner cavity. The filter basket baffle 3022 and the filter screen 301 near the end of the filter basket baffle 3022 are located within the inner cavity of the cap. The outer circumferential surface of the inner cavity of the protective cap 600 is attached to the inner cavity of the first filter tube 100. The protective cap 600 provides a circumferential fixing force for the filter basket 302, further enhancing the stability of the filter core 300. On the other hand, the fluid to be filtered can enter the circumferential surface of the filter core 300 evenly from the fluid gaps on its circumferential surface, preventing solid particles in the fluid to be filtered from directly impacting the filter screen 301. Specifically:

[0056] The protective cap 600 in Embodiment 2 includes two grippers 601, each gripper 601 being a rectangular C-shape. The openings of both grippers 601 face the direction of the filter basket baffle 3022, and their middle ends are connected in a cross-shaped manner. The space surrounded by the two ends of the grippers constitutes the inner cavity of the cap, and the space where the two grippers intersect constitutes the fluid gap.

[0057] In addition, Example 2 uses two grippers as an example. In actual use, the number of grippers can be determined according to the liquid flow rate and pressure loss design, and there is no particular limitation.

[0058] The other components and connections in Example 2 are the same as those in Example 1, and will not be described again here.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
