Description

Technical Field

[0001] This invention relates to the field of computer room cooling technology, and in particular to a computer room cooling device, cooling system and cooling method. Background Technology

[0002] Dust accumulates on the dust filters of computer room cooling units after prolonged use. This dust buildup not only reduces heat dissipation efficiency but can also cause equipment malfunctions. To ensure effective heat dissipation and dust prevention, the dust filters must be easily removable for cleaning. However, removing and cleaning the dust filters can cause temporary shutdowns of the cooling system, affecting its cooling performance and potentially causing damage to the system upon restarting. Summary of the Invention

[0003] Therefore, there is a need to provide a computer room cooling device, cooling system, and cooling method to solve the technical problem that the removal and cleaning of existing dust screens can easily cause temporary shutdowns of the cooling device, which not only affects the cooling effect of the cooling device, but may also cause damage to the cooling device when it is restarted.

[0004] To achieve the above objectives, in a first aspect, the present invention provides a computer room cooling device, comprising:

[0005] The refrigeration mechanism includes a refrigeration unit and a dust filter. The refrigeration unit has an air inlet on the back and a dust filter installed at the air inlet. The refrigeration unit has an air outlet on the front.

[0006] The dust removal mechanism includes a moving component, an adhesive component, and a winding component. The moving component includes a linear module and a limiting slide bar, which are installed on the back of the refrigeration unit along the height direction of the refrigeration unit and located on both sides of the dustproof net. The adhesive component includes a mounting box and an adhesive roller, with the linear module and the limiting slide bar installed on both sides of the mounting box. The mounting box is open on the side closest to the dustproof net, and the adhesive roller is rotatably connected inside the mounting box. The adhesive roller has two or more layers of adhesive tape, with the adhesive side of the tape facing the dustproof net. The winding component includes a winding frame, a winding roller, and a winding motor. The winding frame is installed on the back of the refrigeration unit and located directly above the mounting box. The winding roller is installed on the winding frame, and the first end of the adhesive tape is pasted and fixed on the winding roller. The winding motor is installed on the winding frame, and the output end of the winding motor is connected to the winding roller. The winding motor drives the winding roller to wind up.

[0007] The control mechanism is communicatively connected to both the refrigeration mechanism and the dust removal mechanism.

[0008] The linear module drive mounting box moves up and down along the height of the refrigeration unit, and the tape adheres to the dust on the dustproof net.

[0009] Unlike existing technologies, the above-mentioned technical solution incorporates a dust removal mechanism at the dustproof screen. The adhesive roller, driven by a moving component, unfolds and adsorbs dust from the screen, thus periodically and effectively cleaning the dust and automatically cleaning the refrigeration unit. This prevents dust accumulation and clogging of the dustproof screen, and the cleaning process does not require removing the dustproof screen, thus not affecting refrigeration operation and avoiding restarting the refrigeration unit. This ensures continuous and effective operation and prevents additional wear and tear on the refrigeration unit. Furthermore, the adhesive roller has multiple layers of adhesive tape, with the tape-covered ends attached to the take-up roller, enabling automatic tape rewinding and replacement without manual intervention, making it more convenient to use.

[0010] As one embodiment of the present invention, the dust removal mechanism further includes a first camera, which is installed at the bottom of the mounting box, and is aimed at the dustproof net. The first camera is used to detect the dust coverage rate on the dustproof net and is communicatively connected to the control mechanism.

[0011] When the first camera detects that the dust coverage rate on the dustproof net exceeds the first preset coverage rate, the control mechanism controls the moving component to operate, and the adhesive roller moves downward along the height direction of the refrigeration unit to the bottom. At the same time, the adhesive tape unfolds and adheres to the dust on the dustproof net.

[0012] When the adhesive roller moves upward along the height direction of the refrigeration unit, the winding motor drives the winding roller to wind synchronously. The first camera detects the dust coverage rate on the dustproof net. If the dust coverage rate on the dustproof net detected by the first camera still exceeds the first preset coverage rate, the control mechanism controls the moving component to continue running until the dust coverage rate on the dustproof net is lower than the first preset coverage rate.

[0013] In this way, by setting up a first camera, the number of times the adhesive roller needs to be cleaned can be accurately determined based on the dust coverage rate on the dustproof net, avoiding over-cleaning and waste of adhesive tape.

[0014] In one embodiment of the present invention, the adhesive assembly further includes an adhesive motor and a coupling. The adhesive motor and the coupling are both installed in the mounting box. The output end of the adhesive motor is connected to the adhesive roller through the coupling, and the adhesive motor drives the adhesive roller to rotate.

[0015] In this way, the adhesive motor is connected to the adhesive roller through a coupling, which ensures that the adhesive roller can run idle while also rotating under the action of the adhesive motor to assist in the unfolding or rewinding of the adhesive tape.

[0016] As one embodiment of the present invention, the dust removal mechanism also includes a second camera, which is installed inside the refrigeration unit. A detection hole is opened in the middle of the dustproof net, and the second camera is aligned with the detection hole. The second camera is used to detect the dust coverage rate on the unfolded adhesive tape. The second camera is communicatively connected to the control mechanism.

[0017] When the second camera detects that the dust coverage on the unfolded tape does not exceed the second preset coverage rate, the control mechanism controls the adhesive motor to run, and the adhesive roller rewinds the unfolded tape that has descended to the bottom.

[0018] When the second camera detects that the dust coverage on the unfolded tape exceeds the second preset coverage rate, the control mechanism controls the winding assembly to wind up the unfolded tape that has descended to the bottom.

[0019] In this way, by setting a second camera to detect the dust coverage on the unfolded tape, the tape that is not fully used can be reused, thereby reducing tape consumption and saving costs.

[0020] As one embodiment of the present invention, the dust removal mechanism further includes an adjustment component, which includes two limiting rails, two slides and two elastic elements. The two limiting rails extend along the width direction of the refrigeration unit and are respectively installed on the inner walls of both sides of the mounting box. Each limiting rail corresponds to one slide and one elastic element. The slide slides in the limiting rail. An elastic element is installed between the slide and the limiting rail. An adhesive roller is engaged between the two slides.

[0021] The adjusting component adjusts the position of the adhesive roller along the width of the refrigeration unit so that the adhesive tape always adheres tightly to the outside of the dustproof net.

[0022] Thus, under the elastic force of the elastic element, the slide block drives the adhesive roller to move, ensuring that the adhesive roller always adheres tightly to the outer side of the dustproof net. Consequently, as the moving component moves along the height direction of the refrigeration unit, the adhesive roller rolls under the action of friction, causing the adhesive tape to adhere to the dust on the dustproof net, thereby cleaning the dustproof net.

[0023] In one embodiment of the present invention, the mounting box includes a semi-enclosed box, a protective cover, and two blocking blocks. The protective cover is detachably installed on the top of the semi-enclosed box, and blocking blocks are installed on both sides of the bottom of the protective cover. The blocking blocks correspond to the opening of the slide block and are used to abut against the adhesive roller to prevent the adhesive roller from falling off the slide block.

[0024] Thus, the semi-enclosed box has a removable protective cover on top, making it easy to replace the adhesive roller. Furthermore, a stop block prevents the adhesive roller from detaching from the slide.

[0025] As one embodiment of the present invention, the dust removal mechanism further includes a thickness detection sensor, which is installed on the inner wall of the mounting box. The detection end of the thickness detection sensor is aligned with the side of the adhesive roller, and the thickness detection sensor is used to detect the thickness of the adhesive roller.

[0026] If the thickness detection sensor detects that the thickness of the adhesive roller is lower than the preset thickness, the adhesive tape on the adhesive roller will run out and needs to be replaced.

[0027] In this way, by setting a thickness detection sensor, the thickness of the adhesive tape can be detected in real time, and an alarm will be triggered to prompt replacement when the thickness of the adhesive roller is lower than the preset thickness, thus avoiding cleaning interruption.

[0028] In one embodiment of the present invention, a slit is provided at the bottom of the mounting box near the adhesive roller.

[0029] In this way, dust can easily pass through the gaps, and then the adhesive tape on the adhesive roller will stick and absorb the passing dust.

[0030] In one embodiment of the present invention, the winding assembly further includes a protective cover that covers the outside of the winding roller.

[0031] Thus, by setting up a protective cover to protect the take-up roller, the external environment can be prevented from affecting the function of the take-up assembly.

[0032] To achieve the above objectives, in a second aspect, the present invention also provides a computer room cooling system, including a computer room cooling device as described above by the inventors.

[0033] To achieve the above objectives, in a third aspect, the present invention also provides a method for cooling a computer room, comprising a computer room cooling device as described in any of the above-mentioned claims, and further comprising the following steps:

[0034] S1: The linear module drives the mounting box to move downwards along the height of the refrigeration unit. The first end of the adhesive tape remains fixed. The adhesive tape on the adhesive roller unfolds as the mounting box moves downwards and adheres to the dust on the dustproof net.

[0035] S2: When the mounting box moves down to the bottom, the unfolded tape covers the entire dustproof net. The control mechanism controls the linear module to drive the mounting box to move upward along the height direction of the refrigeration unit. At the same time, the control mechanism controls the winding motor to run synchronously, and the winding roller winds up the unfolded tape.

[0036] S3: Repeat steps S1 to S2 until all dust adheres to the dust screen.

[0037] Unlike existing technologies, the adhesive tape on the adhesive roller unfolds and adheres to dust on the dustproof net as the mounting box moves downwards, thus enabling regular and effective cleaning of the dust on the dustproof net. Furthermore, the take-up roller can rewind the used adhesive tape, automatically rewinding and replacing it, achieving automated cleaning under the control of the mechanism.

The control mechanism is communicatively connected to the refrigeration unit 1 and the dust removal unit 2 respectively. The linear module 211 drives the mounting box 221 to move up and down reciprocally along the height direction Z of the refrigeration unit, and the adhesive tape 2221 adheres to the dust on the dustproof net 12.

[0068] According to some embodiments of this application, please refer to Figure 1 This application provides a computer room cooling system, including a computer room cooling device 100.

[0069] The computer room cooling unit 100 includes a chiller 11, which is an existing computer room cooling indoor unit. Specifically, the chiller 11 includes an indoor unit casing and an evaporator fan 111, an evaporator 112 and a compressor 113 installed in the indoor unit casing. The air inlet of the evaporator fan 111 is connected to the evaporator 112, and the refrigerant outlet of the evaporator 112 is connected to the air intake of the compressor 113.

[0070] The computer room cooling system also includes a computer room cooling outdoor unit 6. The computer room cooling outdoor unit 6 includes an outdoor unit casing, two air-to-water heat exchangers 61, two dry coolers 62, a condenser fan 63, a spray assembly 64, a water collection tank 65, a water-to-refrigerant heat exchanger 66, a circulating water pump 67, a refrigerant pump 68, and an electronic expansion valve 69. The two air-to-water heat exchangers 61 are respectively installed on both sides of the outdoor unit casing, with their air inlets open to the outside air. The two dry coolers 62 are installed in a V-shape in the middle of the outdoor unit casing. A condenser fan 63 is installed on the top of the outdoor unit casing above the dry coolers 62, with its air outlet open to the outside air.

The outlet of the electronic expansion valve 69 is connected to the refrigerant inlet of the evaporator 112.

[0071] The working principle of the computer room cooling system is as follows: The refrigerant first passes through the evaporator 112 for heat exchange, lowering the internal temperature of the computer room. Next, the low-temperature, low-pressure refrigerant gas after heat exchange in the evaporator 112 is compressed by the compressor 113 into a high-temperature, high-pressure refrigerant gas. Then, the high-temperature, high-pressure refrigerant, after compression by the compressor 113, passes through the water-refrigerant heat exchanger 66 for heat exchange and cooling, transferring heat to the water flowing in from the water collection tank 65. The heated water then passes through the air-water heat exchanger 61, transferring the heat of the water to the air, and the hot air is then blown out by the condenser fan 63. Next, the refrigerant, after being cooled by the water-refrigerant heat exchanger 66, passes through the dry cooler 62 for further cooling, transferring heat to the air, and the hot air is then blown out by the condenser fan 63. Finally, the refrigerant, cooled by the water-refrigerant heat exchanger 66 and the dry cooler 62, flows through the electronic expansion valve 69 for throttling before returning to the evaporator 112 for heat exchange.

[0072] According to some embodiments of this application, please refer to Figures 2 to 13This embodiment relates to a computer room cooling device 100, including a cooling mechanism 1, a dust removal mechanism 2, and a control mechanism. The cooling mechanism 1 includes a refrigeration unit 11 and a dustproof net 12. An air inlet is provided on the back of the refrigeration unit 11, and the dustproof net 12 is installed at the air inlet. An air outlet is provided on the front of the refrigeration unit 11. The dust removal mechanism 2 includes a moving component 21, an adhesive component 22, and a winding component 23. The moving component 21 includes a linear module 211 and a limiting slide bar 212. The linear module 211 and the limiting slide bar 212 are installed on the back of the refrigeration unit 11 along the height direction Z of the refrigeration unit and are located on both sides of the dustproof net 12. The adhesive component 22 includes a mounting box 221 and an adhesive roller 222. The two sides of the mounting box 221 are respectively mounted on the linear module 211 and the limiting slide bar 212. The side of the mounting box 221 closest to the dustproof net 12 is open. An adhesive roller 222 is rotatably connected inside the refrigeration unit 21. The adhesive roller 222 has two or more turns of adhesive tape 2221, with the adhesive side of the tape 2221 facing the dustproof net 12. The winding assembly 23 includes a winding frame 231, a winding roller 232, and a winding motor 233. The winding frame 231 is installed on the back of the refrigeration unit 11 and is located directly above the mounting box 221. The winding roller 232 is installed on the winding frame 231. The first end of the adhesive tape 2221 is pasted and fixed on the winding roller 232. The winding motor 233 is installed on the winding frame 231. The output end of the winding motor 233 is connected to the winding roller 232, and the winding motor 233 drives the winding roller 232 to wind up. The control mechanism is communicatively connected to the refrigeration unit 1 and the dust removal unit 2 respectively. The linear module 211 drives the mounting box 221 to move up and down reciprocally along the height direction Z of the refrigeration unit, and the adhesive tape 2221 adheres to the dust on the dustproof net 12.

[0073] An air inlet is provided on the back of the refrigerator 11, and an air outlet is provided on the front of the refrigerator 11. The air outlet is positioned opposite to the air inlet, thus forming an air duct. A dustproof net 12 is provided at the air inlet to prevent external dust from entering.

[0074] The height of the moving component 21 along the height direction Z of the refrigeration unit is greater than the height of the dustproof net 12 along the height direction Z of the refrigeration unit, and the length of the moving component 21 along the length direction X of the refrigeration unit is greater than the length of the dustproof net 12 along the length direction X of the refrigeration unit. The linear module 211 is an existing structure and will not be described further. In this embodiment, the linear module 211 drives the mounting box 221 to move up or down reciprocally along the height direction Z of the refrigeration unit, and the stability of the movement of the mounting box 221 is improved under the action of the limiting slide bar 212. The mounting box 221 has an opening on the side near the dustproof net 12, which is used for the adhesive roller 222 to protrude, so that the adhesive tape 2221 can absorb dust on the dustproof net 12. Optionally, the mounting box 221 is made of transparent material, so that the user can easily observe the use of the adhesive tape 2221 on the adhesive roller 222.

[0075] A take-up roller 232 is mounted on the take-up frame 231. The first end of adhesive tape 2221 is adhered to the take-up roller 232. The take-up roller 232 is fixed in place, and the initial position of the adhesive assembly 22 is the highest point of the moving assembly 21. Thus, the adhesive tape 2221 on the adhesive roller 222 unfolds under the traction of the moving assembly 21, allowing the adhesive tape 2221 to directly peel off dust through physical adhesion, without secondary pollution. The take-up motor 233 drives the take-up roller 232 to rotate counterclockwise to wind up the unfolded adhesive tape 2221. In this embodiment, the dustproof net 12 can be set to a size of 1200mm × 800mm, and the width of the adhesive tape 2221 can be 820mm.

[0076] The control mechanism is connected to the refrigeration mechanism 1 and the dust removal mechanism 2 respectively, and plays a role in coordinating the intelligent start and stop of each mechanism to achieve fully automated cleaning.

[0077] The above technical solution includes a dust removal mechanism 2 at the dustproof net 12. The adhesive roller 222, under the action of the moving component 21, can unfold and adsorb dust on the dustproof net 12, thereby periodically and effectively cleaning the dust on the dustproof net 12. This achieves automatic dust removal for the refrigeration unit 11, preventing dust accumulation and clogging of the dustproof net 12. Furthermore, the dustproof net 12 does not need to be removed during cleaning, thus not affecting the refrigeration operation and avoiding the need to restart the refrigeration unit 11, ensuring its continuous and effective operation and preventing additional wear and tear. In addition, the adhesive roller 222 has multiple loops of adhesive tape 2221, and the take-up roller 232 has the beginnings of the adhesive tape 2221 attached, enabling automatic winding and replacement of the adhesive tape 2221 without manual intervention, making it more convenient to use.

[0078] Existing cleaning rollers tend to scatter dust everywhere during the cleaning process of dust filters, potentially even causing it to enter the refrigeration equipment. Furthermore, some solutions require water to clean the rollers, resulting in wastewater contaminating the surrounding environment. In contrast, this application directly adheres the dust to the adhesive tape 2221 during the dust filter cleaning process, preventing dust from entering the refrigeration equipment and avoiding pollution of the surrounding environment.

[0079] like Figure 6As shown, the dust removal mechanism 2 also includes a first camera 3, which is installed at the bottom of the mounting box 221. The first camera 3 is aimed at the dustproof net 12 and is used to detect the dust coverage rate on the dustproof net 12. The first camera 3 is communicatively connected to the control mechanism. When the first camera 3 detects that the dust coverage rate on the dustproof net 12 exceeds the first preset coverage rate, the control mechanism controls the moving component 21 to run. The adhesive roller 222 moves downward along the height direction Z of the refrigeration unit to the bottom. At the same time, the adhesive tape 2221 unfolds and adheres to the dust on the dustproof net 12. When the adhesive roller 222 moves upward along the height direction Z of the refrigeration unit, the winding motor 233 drives the winding roller 232 to wind synchronously. The first camera 3 detects the dust coverage rate on the dustproof net 12. If the first camera 3 detects that the dust coverage rate on the dustproof net 12 still exceeds the first preset coverage rate, the control mechanism controls the moving component 21 to continue running until the dust coverage rate on the dustproof net 12 is lower than the first preset coverage rate.

[0080] In this embodiment, the camera is installed at the bottom of the mounting box 221 at the end away from the dustproof net 12, so that the camera has a wider angle and can capture a larger area of ​​the dustproof net 12, thereby better detecting the dust coverage on the dustproof net 12.

[0081] In actual use, a preset first coverage rate of 70% can be set. Initially, when the first camera 3 detects a dust coverage rate of 75%, the control mechanism controls the moving component 21 to operate, and the adhesive roller 222 moves downward along the height direction Z of the refrigeration unit to the bottom. At the same time, the adhesive tape 2221 unfolds and adheres to the dust on the dustproof net 12. Afterward, the adhesive roller 222 moves upward along the height direction Z of the refrigeration unit under the action of the moving component 21. During this process, the take-up roller 232 performs synchronous take-up, and the first camera 3 is activated to continue detection. When the first camera 3 detects that the dust coverage rate of the dustproof net 12 still exceeds 70% after the first cleaning, the control mechanism continues to control the moving component 21 to operate until the dust coverage rate on the dustproof net 12 is lower than 70%.

[0082] In this way, by setting the first camera 3, the number of times the adhesive roller 222 needs to be cleaned can be accurately determined according to the dust coverage on the dustproof net 12, avoiding over-cleaning and waste of the adhesive tape 2221.

[0083] like Figure 5 As shown, the adhesive assembly 22 also includes an adhesive motor 223 and a coupling 224. The adhesive motor 223 and the coupling 224 are both installed in the mounting box 221. The output end of the adhesive motor 223 is connected to the adhesive roller 222 through the coupling 224, and the adhesive motor 223 drives the adhesive roller 222 to rotate.

[0084] The adhesive motor can rotate forward (counter-clockwise) or reverse (clockwise). When the adhesive motor rotates forward, it assists in unfolding the adhesive tape 2221. When the adhesive motor rotates in reverse, it winds the unfolded adhesive tape 2221 onto the adhesive roller 222. The speed of the adhesive motor 223 during forward and reverse rotation can be set according to actual conditions. In particular, the speed of the adhesive motor 223 during reverse rotation can be consistent with the moving speed of the moving component 21.

[0085] Thus, the adhesive motor 223 is connected to the adhesive roller 222 via the coupling 224, which ensures that the adhesive roller 222 can rotate idling while the adhesive tape 2221 on the adhesive roller 222 is unfolded under the traction of the moving component 21; it can also rotate under the action of the adhesive motor 223 to assist in the unfolding or rewinding of the unfolded adhesive tape 2221.

[0086] like Figure 4 and Figure 6 As shown, the dust removal mechanism 2 also includes a second camera 4, which is installed inside the refrigeration unit 11. A detection hole 121 is provided in the middle of the dustproof net 12. The second camera 4 is aligned with the detection hole 121 and is used to detect the dust coverage rate on the unfolded adhesive tape 2221. The second camera 4 is communicatively connected to the control mechanism. When the second camera 4 detects that the dust coverage rate on the unfolded adhesive tape 2221 does not exceed the second preset coverage rate, the control mechanism controls the adhesive motor 223 to run, and the adhesive roller 222 winds up the unfolded adhesive tape 2221 that has descended to the bottom. When the second camera 4 detects that the dust coverage rate on the unfolded adhesive tape 2221 exceeds the second preset coverage rate, the control mechanism controls the winding assembly 23 to wind up the unfolded adhesive tape 2221 that has descended to the bottom.

[0087] The second camera 4 can be mounted inside the refrigeration unit 11 via a camera mounting bracket. Without interfering with the cleaning of dust from the dustproof net 12 by the adhesive tape 2221, the second camera 4 can capture images of the unfolded adhesive tape 2221 through the detection hole 121. Optionally, the size of the detection hole 121 can be set larger than the size of the mesh openings on the dustproof net 12, thereby allowing the second camera 4 to obtain a wider angle and capture a larger area of ​​the unfolded adhesive tape 2221.

[0088] Optionally, the second camera 4 can be used in conjunction with the first camera 3. The first camera 3 detects the dust coverage rate on the dustproof net 12, while the second camera 4 detects the dust coverage rate on the unfolded adhesive tape 2221. The two cameras do not interfere with each other, and their detection times are different. The first camera 3 detects the dust coverage rate at the beginning of the cleaning operation and during the process of the adhesive tape 2221 moving upward on the adhesive roller 222 after adhesive application. The second camera 4 detects the dust coverage rate when the adhesive tape 2221 is half-unfolded, when the adhesive tape 2221 is fully unfolded, or in real time during the process of the adhesive tape 2221 gradually unfolding as the adhesive roller 2222 moves downward.

[0089] In actual use, a second preset coverage rate of 60% can be set. When the second camera 4 detects that the dust coverage rate on the unfolded tape 2221 is 50%, the control mechanism controls the adhesive motor 223 to run, and the adhesive roller 222 winds up the unfolded tape 2221 that has descended to the bottom, until the second camera 4 detects that the dust coverage rate on the unfolded tape 2221 exceeds 60%. At this time, the control mechanism controls the winding assembly 23 to wind up the unfolded tape 2221 that has descended to the bottom.

[0090] In this way, by setting a second camera 4 to detect the dust coverage on the unfolded tape 2221, the tape 2221 that is not fully used can be reused, thereby reducing the consumption of tape 2221 and saving costs.

[0091] like Figures 7 to 10 As shown, the dust removal mechanism 2 also includes an adjustment component 24, which includes two limiting rails 241, two slides 242, and two elastic elements 243. The two limiting rails 241 extend along the width direction Y of the refrigeration unit and are respectively installed on the inner walls of both sides of the mounting box 221. Each limiting rail 241 corresponds to one slide 242 and one elastic element 243. The slide 242 slides within the limiting rail 241, and the elastic element 243 is installed between the slide 242 and the limiting rail 241. An adhesive roller 222 is engaged between the two slides 242. The adjustment component 24 adjusts the position of the adhesive roller 222 along the width direction Y of the refrigeration unit so that the adhesive tape 2221 is always tightly attached to the outside of the dustproof net 12.

[0092] The elastic element 243 is elastic, and can elastically contract when subjected to pressure, and can return to its initial shape when the pressure is removed. The elastic element 243 can be made of metallic elastic materials such as metal springs, or it can be made of non-metallic elastic materials such as rubber and silicone.

[0093] In this embodiment, the limiting track 241 is U-shaped, and the slide block 242 slides within the U-shape. Optionally, the slide block 242 includes a hollow slider 2421 and a support base 2422. The hollow slider 2421 slides within the limiting track 241, and the support base 2422 is fixed to one side of the hollow slider 2421. A U-shaped notch 2423 is provided at the top of the support base 2422, and the roller heads on both sides of the adhesive roller 222 are inserted into the corresponding U-shaped notches 2423. An elastic element 243 is installed between the hollow slider 2421 and the inner wall of one end of the limiting track 241. The hollow slider 2421 is also U-shaped, and the two U-shaped structures are complementary, ensuring the stability of the slide block 242's sliding. In some embodiments, such as... Figure 10 As shown, there are two elastic elements 243 spaced apart along the height direction Z of the refrigerator, and the length of each elastic element 243 is between the maximum compressed length and half of the original length.

[0094] In this way, the elastic element 243 is always in a compressed state. Under the elastic force of the elastic element 243, the slide 242 drives the adhesive roller 222 to move, thereby ensuring that the adhesive roller 222 is always in close contact with the outer side of the dustproof net 12. Thus, when the moving component 21 moves along the height direction Z of the refrigeration unit, the adhesive roller 222 rolls under the action of friction, thereby causing the adhesive tape 2221 to adhere the dust on the dustproof net 12, achieving the cleaning of the dustproof net 12.

[0095] like Figures 11 to 13 As shown, the mounting box 221 includes a semi-enclosed box 2211, a protective cover 2212, and two blocking blocks 2213. The protective cover 2212 is detachably installed on the top of the semi-enclosed box 2211. Blocking blocks 2213 are installed on both sides of the bottom of the protective cover 2212. The blocking blocks 2213 correspond to the opening of the slide 242. The blocking blocks 2213 are used to abut against the adhesive roller 222 to prevent the adhesive roller 222 from falling off the slide 242.

[0096] The semi-enclosed box 2211 has an opening on the side near the dustproof net 12, and the top of the semi-enclosed box 2211 can be detachably connected to the protective cover 2212 via fasteners. Optionally, the semi-enclosed box 2211 and the protective cover 2212 can be made of transparent material to facilitate observation of the application of the adhesive tape 2221 on the adhesive roller 222.

[0097] When installing the adhesive roller 222, directly align the roller head of the adhesive roller 222 with the opening of the slide block 242 (which can be a U-shaped bayonet 2423). This makes it easy to set the adhesive roller 222 inside the slide block 242. Then, use the blocking block 2213 to block the opening of the slide block 242 to prevent the adhesive roller 222 from coming off the slide block 242.

[0098] In this embodiment, as Figure 12 and Figure 13As shown, a first external protrusion 2214 is fixed to both sides of the semi-enclosed box 2211, and a second external protrusion 2216 is fixed to both sides of the protective cover 2212. The first external protrusion 2214 and the second external protrusion 2216 have the same structure and are stacked one on top of the other. The first external protrusion 2214 and the second external protrusion 2216 are connected by a bolt assembly 25. The bolt assembly 25 has a structure similar to a hand-tightening screw. By controlling the position of the bolt assembly 25, the combination or separation state of the semi-enclosed box 2211 and the protective cover 2212 can be switched. When the semi-enclosed box 2211 and the protective cover 2212 are combined, the adhesive roller 222 is prevented from coming out of the semi-enclosed box 2211. When the semi-enclosed box 2211 and the protective cover 2212 are separated, the adhesive roller 222 can be installed or replaced.

[0099] Specifically, a first threaded hole 2215 is formed at the top of the first outer protrusion 2214, a groove 2217 is formed at the bottom of the second outer protrusion 2216, and a second threaded hole 2218 communicating with the groove 2217 is formed at the top of the second outer protrusion 2216. The inner diameter of the groove 2217 is larger than the diameter of the first threaded hole 2215, the diameter of the first threaded hole 2215 is larger than the diameter of the second threaded hole 2218, and the height of the groove 2217 along the height Z direction of the refrigerator is greater than the height of the first threaded hole 2215 along the height Z direction of the refrigerator.

[0100] The bolt assembly 25, from bottom to top along the height Z direction of the refrigeration unit, includes a first screw 251, a second screw 252, and an end head 253. The first screw 251 is threaded into a first threaded hole 2215, the second screw 252 is threaded into a second threaded hole 2218, and the end head 253 has threads on its periphery for easy rotation. The first screw 251, the second screw 252, and the end head 253 are integrally cast. In actual use, rotating the end head 253 counterclockwise allows the first screw 251 to be fully positioned within the slot 2217, enabling the separation of the semi-enclosed box 2211 from the protective cover 2212. The bolt assembly 25 will not detach from the protective cover 2212, preventing its loss. Rotating the end 253 clockwise causes the first screw 251 to be screwed into the first threaded hole 2215, which can close the semi-enclosed box 2211 and the protective cover 2212, improving the convenience of using the protective cover 2212.

[0101] Thus, by providing a detachable protective cover 2212 to the top of the semi-enclosed box 2211, it is convenient to replace the adhesive roller 222. In addition, the blocking block 2213 prevents the adhesive roller 222 from falling off the slide 242 and fixes the adhesive roller 222 at the Z position in the height direction of the refrigeration unit.

[0102] like Figure 6As shown, the dust removal mechanism 2 also includes a thickness detection sensor 5. The thickness detection sensor 5 is installed on the inner wall of the mounting box 221. The detection end of the thickness detection sensor 5 is aligned with the side of the adhesive roller 222. The thickness detection sensor 5 is used to detect the thickness of the adhesive roller 222. If the thickness detection sensor 5 detects that the thickness of the adhesive roller 222 is lower than the preset thickness, the adhesive tape 2221 on the adhesive roller 222 is used up and needs to be replaced.

[0103] The thickness detection sensor 5 can be a laser triangulation sensor or a third camera. The preset thickness can be 40mm. In some embodiments, the dust removal mechanism 2 also includes an alarm, which is communicatively connected to the control mechanism. The alarm can alert personnel.

[0104] Thus, by setting the thickness detection sensor 5, the thickness of the adhesive tape 2221 can be detected in real time, and an alarm will be triggered to prompt replacement when the thickness of the adhesive roller 222 is lower than the preset thickness, so as to avoid cleaning interruption.

[0105] like Figure 9 As shown, a slit 2219 is provided at the bottom of the mounting box 221 near the adhesive roller 222.

[0106] Optionally, the width of the gap 2219 along the width direction Y of the refrigeration unit is less than half the width of the mounting box 221 along the width direction Y of the refrigeration unit.

[0107] In this way, dust can easily pass through the gap 2219, and then the adhesive tape 2221 on the adhesive roller 222 will stick and absorb the passing dust.

[0108] like Figure 6 As shown, the take-up assembly 23 also includes a protective cover 234, which covers the take-up roller 232.

[0109] The protective cover 234 can be easily opened or closed to remove the wound tape 2221 on the take-up roller 232 or to re-attach new tape 2221. Optionally, the protective cover 234 can be made of transparent material to facilitate observation of the wound tape 2221 on the take-up roller 232.

[0110] Thus, by setting up a protective cover 234 to protect the take-up roller 232, the take-up roller 232 is prevented from being affected by the external environment (such as rainy weather), thereby affecting the function of the take-up assembly 23.

[0111] According to some embodiments of this application, this embodiment also relates to a computer room cooling method, including a computer room cooling device 100, and further includes the following steps:

[0112] S1: The linear module 211 drives the mounting box 221 to move downward along the height direction Z of the refrigerator. The first end of the adhesive tape 2221 remains fixed. The adhesive tape 2221 on the adhesive roller 222 unfolds as the mounting box 221 moves downward and adheres to the dust on the dustproof net 12.

[0113] S2: When the mounting box 221 moves down to the bottom, the unfolded tape 2221 covers the entire dustproof net 12. The control mechanism controls the linear module 211 to drive the mounting box 221 to move upward along the height direction Z of the refrigeration unit. At the same time, the control mechanism controls the winding motor 233 to run synchronously, and the winding roller 232 winds up the unfolded tape 2221.

[0114] S3: Repeat steps S1 to S2 until all dust adheres to the dustproof net 12.

[0115] In step S2, it is important to note that the winding speed of the take-up motor 233 is matched with the moving speed of the linear module 211 to prevent the adhesive tape 2221 from loosening or tearing. In some embodiments, the winding speed of the take-up motor 233 may also be set to be slower than the moving speed of the linear module 211.

[0116] The technical solution of this application allows the adhesive tape 2221 on the adhesive roller 222 to unfold and adhere to the dust on the dustproof net 12 as the mounting box 221 moves downward, thereby periodically and effectively cleaning the dust on the dustproof net 12. In addition, the take-up roller 232 can take up the used adhesive tape 2221, automatically taking up and replacing the adhesive tape 2221, and realizing automated cleaning under the action of the control mechanism.

[0117] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection of the present invention. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of the present invention, or equivalent structural or procedural transformations made using the content of the present invention's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of patent protection of the present invention.
