[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] The invention provides a filtering device.

[0054] Please refer to Figures 1 to 3 , in one embodiment of the present invention, the filtering device comprises a filter box 4, a filter element 5 and a guide device 6;

[0055] The filter element 5 includes a spacer 51 and two filter tubes 52. The spacer 51 is installed in the filter box 4 and divides the interior of the filter box 4 into a liquid inlet chamber 401 and a liquid discharge chamber 402. The two filter tubes 52 are embedded in the spacer 51 at intervals, and the pipe openings of the filter tubes 52 are flush with the spacer 51.

[0056] The guide device 6 includes a pusher 61 and two guide boxes 62. The two guide boxes 62 are slidably disposed in the liquid inlet cavity 401 and the liquid discharge cavity 402, respectively. A preset distance is left between each guide box 62 and the bottom plate of the filter box 4. A first connecting hole 621 is provided on the guide box 62.

[0057] The backwash inlet pipe 421 and the backwash outlet pipe 410 are both connected to the filter box 4, the backwash inlet pipe 421 is connected to the liquid inlet chamber 401, the backwash outlet pipe 410 is connected to the liquid discharge chamber 402, and the filter box outlet pipe 412 and the filter box inlet pipe 411 are respectively connected to the two guide boxes 62;

[0058] In the initial state, the first connecting holes 621 of the two guide boxes 62 are both connected to one of the filter tubes 52; the pushing member 61 is used to drive the two guide boxes 62 to move along the spacer block 51, so that the first connecting holes 621 of the two guide boxes 62 are switched to be connected to the other filter tube 52, and the backwash inlet tube 421, the liquid inlet chamber 401, one of the filter tubes 52, the liquid discharge chamber 402 and the backwash outlet tube 410 are connected in sequence.

[0059] Please refer again Figure 2It can be understood that, in this embodiment, a directional closed chamber is formed between the guide box 62, the filter box 4 and the spacer block 51 to ensure that the liquid flows along a fixed path and does not leak from the guide box 62 into the filter box 4.

[0060] Please refer again Figure 1 In this embodiment, the filter box outlet pipe 412 is connected to the liquid inlet pipe 2 of the liquid cooling cabinet, and the filter box inlet pipe 411 is connected to the coolant source, so that the coolant continuously enters the liquid cooling cabinet through the filtering device and the liquid inlet pipe 2 to cool and dissipate heat for the equipment in the liquid cooling cabinet.

[0061] Please refer to Figure 5 (a) and Figure 5 (d) When it is necessary to clean the filter tube 52 currently in use, the pusher 61 pushes the two guide boxes 62 to move toward the other filter tube 52, so that the first connecting hole 621 is aligned with the other filter tube 52 on the spacer 51, and at this time, the filter box inlet pipe 411 and the filter box outlet pipe 412 are still connected to the two guide boxes 62 respectively; the coolant continues to be input, and after being filtered by the other filter tube 52, the coolant enters the liquid cooling cabinet 1 through the guide box 62, the filter box outlet pipe 412 and the liquid inlet pipe 2.

[0062] See also Figure 5 (f), at the same time, the backwashing liquid is introduced into the liquid inlet chamber 401 of the filter box 4 through the backwashing inlet pipe 421, and then discharged into the liquid discharge chamber 402 through the filter tube 52 to be cleaned, and finally discharged through the backwashing outlet pipe 410. Since the original flow direction of the coolant through the filter tube 52 is from the liquid discharge chamber 402 to the liquid inlet chamber 401, the backwashing liquid can flow from the non-filtering side to the filtering side of the filter tube 52 to flush the impurities on the filter tube 52. The flushing liquid drives the impurities to be discharged through the backwashing outlet pipe 410, which is convenient for cleaning the filter tube 52. It does not affect the continuous delivery of the coolant to the liquid cooler 1, and can also realize regular backwashing and cleaning of the filter tube 52, thereby increasing the service life of the filter tube 52 and reducing the number of shutdowns for maintenance.

[0063] In this embodiment, the filter tube 52 includes a mounting tube and a filter screen. The filter screen is detachably mounted on the mounting tube, and the pipe is embedded in the spacer block 51 .

[0064] As an optional manner of this embodiment, the number of the first connecting hole 621 on the guide box 62 may be one, and the hole diameter of the first connecting hole 621 is larger than the tube diameter of the filter tube 52 .

[0065] Please refer again Figure 3As another optional manner of this embodiment, the number of the first connection holes 621 on the guide box 62 is two, and the two first connection holes 621 are arranged at intervals.

[0066] The diameter of the first connecting hole 621 may be greater than or equal to the diameter of the filter tube 52 .

[0067] Please refer again Figure 5 When backwashing a filter tube 52 currently in use, the pusher 61 pushes the two guide boxes 62 toward the other filter tube 52, so that the current first connecting hole 621 is separated from the filter tube 52 to be cleaned, and the other first connecting hole 621 is aligned with the other filter tube 52. By setting two first connecting holes 621, the distance that the pusher 61 pushes the guide box 62 to move can be reduced, and the pushing stroke of the pusher 61 and the size of the filter box 4 can be reduced.

[0068] In one embodiment, the filter box 4 can be set as a box structure, the backwash inlet pipe 421 is directly connected to the liquid inlet chamber 401, and the backwash outlet pipe 410 is directly connected to the liquid discharge chamber 402; wherein, the backwash inlet pipe 421 can be connected to the output end of the backwashing equipment, and the backwash outlet pipe 410 is connected to the collection container.

[0069] For example, the backwashing equipment includes a water pump, a water tank, cleaning liquid and a pipeline. The input end of the water pump is connected to the water tank through a pipeline, and the output end of the water pump is connected to the backwashing inlet pipe 421 through a pipeline. The cleaning liquid is stored in the water tank.

[0070] During filtration, the water pump works to introduce the backwash liquid into the liquid inlet chamber 401 through the backwash inlet pipe 421 . The backwash liquid flows from the non-filtering side to the filtering side of the filter tube 52 to be cleaned and then enters the liquid discharge chamber 402 , and is finally discharged through the backwash outlet pipe 410 .

[0071] Please refer to Figures 2 to 4 In another embodiment, the filter box 4 includes a box body 41 and a box body 42, the box body 41 and the box body 42 are connected up and down, and the spacer 51 divides the interior of the box body 41 into the liquid inlet chamber 401 and the liquid discharge chamber 402;

[0072] The liquid outlet pipe 422 and the backwash inlet pipe 421 are both connected to the box body 42. A through hole 413 is provided on the bottom plate of the box body 41 to connect the liquid inlet cavity 401 with the box body 42. The backwash outlet pipe 410 passes through the bottom plates of the box body 42 and the box body 41 in sequence and is connected to the liquid discharge cavity 402.

[0073] The filtering device further comprises a second switching member 8 and two first switching members 7 . In an initial state, the two first switching members 7 are respectively used to control the closing of the backwash outlet pipe 410 and the through hole 413 , and the second switching member 8 is used to control the opening of the liquid outlet pipe 422 .

[0074] Please refer again Figure 1 In this embodiment, the backwash inlet pipe 421 is connected to the drain pipe 3 of the liquid cooling cabinet. The above structure can realize that the coolant discharged from the liquid cooling cabinet is used as the cleaning liquid of the filter tube 52.

[0075] It can be understood that the box body 41 is an openable storage structure, and the box body 41 and the box body 42 can be detachably connected.

[0076] The specific usage principles are as follows:

[0077] Please refer to Figure 4 and Figure 5 When it is necessary to clean the filter tube 52 currently in use, the pusher 61 pushes the two guide boxes 62 to move, switches the position of the first connecting hole 621, separates one first connecting hole 621 from the filter tube 52 to be cleaned, and aligns the other first connecting hole 621 with the other filter tube 52 to ensure continuous delivery of the coolant; the first switching member 7 opens the through hole 413 to connect the liquid inlet cavity 401 and the box body 42, the first switching member 7 opens the recoil outlet pipe 410, and the second switching member 8 closes the liquid outlet pipe 422.

[0078] During the cooling liquid circulation process, the liquid discharged from the drain pipe 3 enters the interior of the box body 42 through the backwash inlet pipe 421, then enters the liquid inlet cavity 401 of the box body 41 through the through hole 413, and then flows into the drain cavity 402 through the filter tube 52 to be cleaned, and the filter tube 52 is backwashed, and the impurities washed away are discharged from the backwash outlet pipe 410 along with the cooling liquid;

[0079] When cleaning is completed, the first switching member 7 closes the through hole 413 and the recoil outlet pipe 410, and the second switching member 8 opens the liquid outlet pipe 422. At this time, during the coolant circulation process, the coolant is discharged through the drain pipe 3, enters the box body 42 through the recoil inlet pipe 421, and then is discharged from the liquid outlet pipe 422.

[0080] Therefore, the filter tube 52 can be backwashed by utilizing the coolant discharged from the liquid cooling cabinet, without the need to set up additional backwashing equipment.

[0081] The liquid outlet pipe 422 can be connected to a subsequent coolant treatment device to cool the coolant. The recoil outlet pipe 410 is connected to a collection container through a pipeline to collect the coolant carrying impurities. The collection container can be regularly treated and the coolant can be recycled.

[0082] As an optional method of this embodiment, the first switching member 7 and the second switching member 8 may use electromagnetic valves or electric valves respectively. A pipeline may be arranged at the position corresponding to the through hole 413 to facilitate the assembly of the second switching member 8.

[0083] Please refer to Figure 3 and Figure 4 As another optional method of this embodiment, the first switching member 7 includes an upper sealing plate 71 and a connecting shaft 73, and two switching holes 72 are respectively provided at both ends of the upper sealing plate 71, and the connecting shaft 73 is used to connect the upper sealing plate 71 and the guide box 62; wherein, the two first switching members 7 are respectively located in the liquid inlet chamber 401 and the liquid discharge chamber 402.

[0084] A second connection hole 622 is formed on each of the guide boxes 62 , and one of the second connection holes 622 is located between two of the first connection holes 621 .

[0085] The above-mentioned structure can realize backwashing of the two filter tubes 52 in sequence and prevent the impurities from backwashing from entering the filter box outlet pipe 412, thereby further improving the service life of the filter device and reducing the number of shutdowns for maintenance.

[0086] The specific working principle is as follows:

[0087] Please refer to Figure 5 (a) to Figure 5 (c) and Figure 6 (a) to Figure 6 (c) When one filter tube 52 is in the filtering state and the other filter tube 52 is in the ready-to-use state, at this time, the upper sealing plate 71 in one first switching member 7 blocks the through hole 413, and the upper sealing plate 71 in the other first switching member 7 blocks the recoil outlet pipe 410, and at the same time, the second switching member 8 opens the liquid outlet pipe 422.

[0088] Please refer to Figure 5 (d) to Figure 5 (f) and Figure 6 (d) to Figure 6 (f) When one filter tube 52 is switched to a filtering state and the other filter tube 52 is switched to a backwashing state, the pusher 61 pushes the two guide boxes 62 so that the second connection holes 622 on the two guide boxes 62 are aligned with the filter tube 52 to be used, the two first connection holes 621 are staggered with the filter tube 52 to be cleaned, and the spacer 51 closes the two first connection holes 621;

[0089] During the movement of the two guide boxes 62, the upper sealing plate 71 of a first switching member 7 is driven to move upward or downward through the connecting shaft 73, so that the switching hole 72 at the upper end or the switching hole 72 at the lower end of the upper sealing plate 71 in the first switching member 7 is aligned with the through hole 413, so that the box body 41 is connected with the box body 42; the switching hole 72 at the upper end or the switching hole 72 at the lower end of the upper sealing plate 71 in the other first switching member 7 is aligned with the backwash outlet pipe 410 and connected, and at the same time the second switching member 8 closes the liquid outlet pipe 422.

[0090] In the process of using the pusher 61 to push the guide box 62 to switch the use status of the two filter tubes 52 , the two first switching members 7 can be driven simultaneously to adjust the switch status of the through hole 413 and the backwash outlet tube 410 .

[0091] See also Figure 6 (f) The liquid discharged from the drain pipe 3 enters the interior of the box body 42 through the backwash inlet pipe 421, then enters the liquid inlet chamber 401 of the box body 41 through the through hole 413, and then flows into the drain chamber 402 through the filter tube 52 to be cleaned, and the filter tube 52 is backwashed. The impurities flushed are discharged from the backwash outlet pipe 410 along with the coolant; the impurities flushed will not enter the filter box outlet pipe 412, nor will they enter the liquid cooling cabinet.

[0092] Please refer to Figure 3 and Figure 4 , a strip-shaped hole 414 is also provided on the bottom plate of the box body 41;

[0093] The second switching member 8 includes a lower sealing plate 81 and a connecting arm 83. Two drainage holes 82 are spaced apart on the lower sealing plate 81. The lower sealing plate 81 is attached to the bottom plate of the box body 42. One of the drainage holes 82 is connected to the liquid outlet pipe 422. One end of the connecting arm 83 is connected to the lower sealing plate 81, and the other end of the connecting arm 83 is connected to an upper sealing plate 71 through the strip hole 414. The upper sealing plate 71 covers and closes the strip hole 414.

[0094] See also Figure 5 (b) or Figure 6 (b), when one filter tube 52 is in a filtering state and the other filter tube 52 is in a ready-to-use state, the drainage hole 82 at the upper end or the lower end of the lower sealing plate 81 is connected to the liquid outlet pipe 422;

[0095] See also Figure 5 (e) or Figure 6(e) When switching one filter tube 52 to a filtering state and the other filter tube 52 to a backwashing state, the pusher 61 pushes the two guide boxes 62 so that the second connecting holes 622 on the two guide boxes 62 are aligned with the filter tube 52 to be used. Similarly, when the two guide boxes 62 drive the corresponding upper sealing plates 71 to move through the connecting shaft 73, an upper sealing plate 71 drives a lower sealing plate 81 to follow the movement through the connecting arm 83, so that the switching hole 72 at the upper end or the switching hole 72 at the lower end of the upper sealing plate 71 in the first switching member 7 is aligned with the through hole 413, so that the liquid inlet chamber 401 is connected to the box body 42; the switching hole 72 at the upper end or the switching hole 72 at the lower end of the upper sealing plate 71 in the second switching member 8 is aligned and connected with the backwashing outlet pipe 410, and the lower end or the upper end of the lower sealing plate 81 blocks the liquid outlet pipe 422.

[0096] Therefore, in the process of using the pusher 61 to push the guide box 62 to switch the use status of the two filter tubes 52, the first switching member 7 and the second switching member 8 can be driven simultaneously to adjust the connection status of the through hole 413, the backwash outlet tube 410 and the liquid outlet tube 422.

[0097] In this embodiment, the upper sealing plate 71 covers and closes the strip hole 414, and the strip hole 414 is always located below the upper sealing plate 71, thereby preventing the strip hole 414 from connecting the box body 41 and the box body 42, and preventing the coolant discharged through the liquid outlet pipe 422 from entering the box body 41 through the strip hole 414 when not in the backwashing state.

[0098] Please refer again Figure 2 The pushing member 61 includes a pushing cylinder 611 and an F-shaped frame 612. The pushing cylinder 611 is installed on the box body 41. The first end of the F-shaped frame 612 is installed on the output end of the pushing cylinder 611. The second end and the third end of the F-shaped frame 612 pass through the filter box 4 and are respectively connected to the two guide boxes 62.

[0099] When the guide box 62 needs to be moved, the push cylinder 611 pulls or pushes the F-shaped frame 612 , and the F-shaped frame 612 drives the two guide boxes 62 to move along the spacer block 51 .

[0100] In this embodiment, the F-shaped frame 612 and the filter box 4 are mechanically sealed at the penetration point.

[0101] In other embodiments, the pushing member 61 includes a pushing cylinder 611, an L-shaped frame and a U-shaped rod. The pushing cylinder 611 is installed on the filter box 4 through the L-shaped frame, and the U-shaped rod is installed at the output end of the pushing cylinder 611. The two ends of the U-shaped rod pass through the box body 41 and are correspondingly connected to the two guide boxes 62.

[0102] The invention also provides a liquid cooling cabinet.

[0103] Please refer to Figure 1 , Figure 7 and Figure 8 , In one embodiment of the present invention, the liquid cooling cabinet comprises: a liquid cooling cabinet 1, a liquid inlet pipe 2, a liquid discharge pipe 3 and the filtering device;

[0104] The liquid inlet pipe 2 is connected to the liquid cooling cabinet 1 and the filter box outlet pipe 412 , and the liquid discharge pipe 3 is connected to the liquid cooling cabinet 1 and the backwash inlet pipe 421 .

[0105] When the coolant is circulated, the coolant enters the interior of the guide box 62 through the filter box inlet pipe 411 through the opening side of the corresponding guide box 62, and then enters the corresponding filter tube 52 through the first connecting hole 621. After filtering the coolant through a corresponding filter tube 52, it enters the interior of the guide box 62 through the first connecting hole 621 on the other guide box 62, and enters the filter box outlet pipe 412 through the opening of the guide box 62, and then enters the interior of the liquid cooling cabinet 1 through the liquid inlet pipe 2. After the coolant is heat exchanged by the equipment inside the liquid cooling cabinet 1, it is discharged through the drain pipe 3, the backwash inlet pipe 421 and the liquid outlet pipe 422, and flows into the subsequent coolant treatment device for heat exchange and cooling, and finally circulates back and enters through the filter box inlet pipe 411 to form circulating cooling.

[0106] In this embodiment, water pumps (not shown) are provided on both the liquid inlet pipe 2 and the liquid discharge pipe 3. The water pump on the liquid inlet pipe 2 is used to pump the coolant into the liquid cooling cabinet 1 at a preset speed. By providing a water pump on the liquid discharge pipe 3, the discharge speed of the coolant can be controlled to match the entry speed of the coolant.

[0107] At the same time, by arranging a water pump on the drain pipe 3, sufficient impact force can be provided when backwashing the filter tube 52 to ensure the cleaning effect.

[0108] Among them, the specific structure of the filtering device refers to the above embodiments. Since the liquid cooling cabinet uses all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0109] See also Figure 1 The liquid inlet pipe 2 includes a main pipe 21 and a plurality of branch pipes 22 and a regulating valve 23. The branch pipes 22 and the regulating valves 23 are arranged one by one. The plurality of branch pipes 22 are arranged at intervals on one side of the liquid cooling cabinet 1. The branch pipes 22 connect the main pipe 21 and the liquid cooling cabinet 1.

[0110] The plurality of branch pipes 22 divide the interior of the liquid cooling cabinet 1 into a plurality of cooling areas; each cooling area is provided with at least one temperature sensor.

[0111] When the equipment inside the liquid cooling cabinet 1 is working, the temperature sensors in the corresponding areas monitor the temperature conditions of their respective areas. When the temperature detected by the temperature sensor in a certain area is higher than that in other areas, the regulating valve 23 on the corresponding branch pipe 22 is adjusted to increase the flow rate of the liquid inside the branch pipe 22. When there is a preset temperature difference between the temperatures of multiple areas, the regulating valves 23 on the multiple branch pipes 22 adjust the flow rate of the coolant inside each branch pipe 22 according to the temperature. The flow rate is adjusted accordingly according to the corresponding temperature, so that the flow rate of the coolant can be controlled in different areas according to the different regional temperatures, thereby realizing targeted heat dissipation and cooling functions, and improving the cooling and heat dissipation effect of the equipment.

[0112] See also Figure 1 In this embodiment, the number of the branch pipes 22 is no less than three.

[0113] When the number of branch pipes 22 is three, the interior of the corresponding liquid cooling cabinet 1 is divided into three cooling areas, and each cooling area is provided with at least two temperature sensors, which are respectively provided on both sides of the liquid cooling cabinet 1, namely, the liquid inlet side and the liquid discharge side.

[0114] The regulating valve 23 may be a solenoid valve or an electric valve.

[0115] See also Figure 7 The drain pipe 3 is connected to the liquid cooling cabinet 1 through a plurality of connecting pipes 31 .

[0116] The number of connecting pipes 31 corresponds to the number and position of branch pipes 22. Through the corresponding multiple connecting pipes 31, the coolant entering the branch pipes 22 in the corresponding area is discharged through the corresponding connecting pipes 31, thereby avoiding the situation where the coolant in each area flows to one outlet when one outlet is set, and the coolant after heat exchange contacts with equipment in other areas, resulting in poor heat exchange effect.

[0117] Please refer again Figure 1 , perforated frames 101 are installed on both sides of the liquid cooling cabinet 1.

[0118] The perforated rack 101 is used to install the equipment to be cooled and dissipated. The perforated rack 101 is provided to facilitate the installation of the equipment to be cooled and dissipated. A spacing is left between the perforated rack 101 and the side wall of the liquid cooling cabinet 1 to facilitate the coolant to enter the interior of the liquid cooling cabinet 1 through the branch pipe 22 and be discharged through the drain pipe 3.

[0119] Please refer again Figure 8 A shell 9 is provided on the outside of the liquid cooling cabinet 1 ; a top cover 10 is provided on the top of the liquid cooling cabinet 1 to prevent external debris from falling into the interior of the liquid cooling cabinet 1 .

[0120] The invention also provides a cooler component with a wet film.

[0121] See also Fig. 9 The cooler assembly with wet film includes the liquid cooling cabinet, the cooling box 30, the exhaust fan 20, two spray devices 40, a wet film 50 and a coil 60, the exhaust fan 20 is installed on the top of the cooling box 30, and the two coils 60 are installed inside the cooling box 30 at intervals. The spray device 40, the wet film 50 and the coil 60 are arranged in a one-to-one correspondence, one spray device 40 is arranged toward one coil 60, and one wet film 50 is located between a corresponding spray device 40 and a corresponding coil 60; wherein, the two ends of the coil 60 are respectively connected to the filter box inlet pipe 411 and the liquid outlet end of the liquid cooling cabinet.

[0122] In this embodiment, the liquid outlet end of the liquid cooling cabinet is the liquid outlet pipe 422 .

[0123] In this embodiment, the two coils 60 are in a V-shape. In the present invention, the cooler assembly with wet film is a cooling liquid processing device.

[0124] After the coolant passes through the liquid cooling cabinet 1 to exchange heat with the equipment inside the liquid cooling cabinet 1, it flows into the coil 60 through the drain pipe 3, the filter box 4 and the pipeline, exchanges heat with the coolant through the coil 60 and then flows back to the liquid cooling cabinet 1.

[0125] When the coolant is exchanged with heat through the coil 60, the spray device 40 sprays liquid onto the wet film 50, and the liquid adheres to the wet film 50. At the same time, the exhaust fan 20 works to make the air flow pass through the wet film 50 and the coil 60 in sequence, and then be discharged through the exhaust fan 20. When the air flow passes through the wet film 50, it exchanges heat with the liquid on the wet film 50 to pre-cool the gas. The pre-cooled air flow then exchanges heat with the coil 60 to take away the heat on the coil 60, so that the coil 60 can continuously exchange heat with the coolant.

[0126] Wherein, air inlets are provided on both sides of the cooling box 30, so that when the exhaust fan 20 is working, air flow can enter through the air inlet holes and pass through the wet film 50 and the coil 60 in sequence to achieve further heat exchange.

[0127] Among them, the specific structure of the filtering device refers to the above embodiments. Since the cooler assembly with wet film uses all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0128] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
