Description

Technical Field

[0001] This utility model relates to the field of computer room heat dissipation technology, and in particular to a computer room water cooling device. Background Technology

[0002] As an important component of data centers, server clusters, and other high-performance computing facilities, computer rooms contain multiple server racks. The equipment inside these racks generates a significant amount of heat during operation. Water cooling technology, as an efficient heat dissipation method, has been widely used in the field of computer room cooling. Water cooling systems typically include core components such as water-cooled heat exchange pipes. Through the circulation of coolant within the water-cooled heat exchange pipes, the heat generated by the equipment is carried away and dissipated into the external environment, thereby effectively cooling the equipment in the computer room. Compared with traditional air cooling, water cooling has significant advantages such as high heat dissipation efficiency and low noise, and can better meet the requirements of computer rooms for heat dissipation performance and operating environment.

[0003] In some existing computer room water cooling solutions, heat exchange tubes are arranged inside the computer chassis, and cooling water flows through the heat exchange tubes to remove heat. The cooled water, after absorbing heat, is then cooled down through structures such as cooling towers. This type of solution can use ordinary water as the cooling water, resulting in lower construction and operating costs. However, because the cooling water needs to come into contact with the external environment during cooling, some impurities can be introduced into the cooling water. Over long-term use, these impurities can easily remain or adhere to the inside of the heat exchange tubes, leading to a reduction in heat exchange efficiency.

[0004] Therefore, a water-cooling device for computer rooms is proposed. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 5 This utility model provides a technical solution:

[0028] A water-cooling device for a computer room includes a chassis 1, a heat exchange tube 2 is installed inside the chassis 1, the heat exchange tube 2 is arranged in a serpentine manner, an inlet pipe 3 and an outlet pipe 4 are respectively installed at both ends of the heat exchange tube 2, an automatic cleaning mechanism 5 is installed in the middle of the inlet pipe 3, and a collection and recycling mechanism 6 is installed in the middle of the outlet pipe 4.

[0029] The automatic cleaning mechanism 5 includes a cleaning pipe 51 located in the middle of the liquid inlet pipe 3, a conveying pipe 52 located on the side wall of the cleaning pipe 51, a vertical pipe 53 located at the top of the conveying pipe 52, a first electric push rod 54 located at the top of the cleaning pipe 51, a feeding head 55 located in the middle of the cleaning pipe 51, a feeding trough 56 located in the middle of the feeding head 55, a sponge ball 57 located inside the feeding trough 56, the diameter of the sponge ball 57 being larger than the diameter of the heat exchange tube 2, the feeding head 55 being fixedly connected to the output end of the first electric push rod 54, and a conveying assembly 58 located in the middle of the conveying pipe 52.

[0030] Specifically, such as Figure 4 As shown, the conveying assembly 58 includes a conveying rod 581 threadedly connected to one end of the conveying pipe 52. A conveying head 582 is installed at one end of the conveying rod 581. A conveying groove 583 is provided on the side wall of the conveying head 582. The conveying groove 583 is adapted to the sponge ball 57.

[0031] Specifically, such as Figure 4 As shown, a limit block 7 is provided at the bottom of the cleaning tube 51, and a buffer pad 8 is provided at the top of the limit block 7.

[0032] Specifically, such as Figure 4 As shown, sealing rings 9 are provided at both ends of the feeding head 55, and the sealing rings 9 are in contact with the side wall of the cleaning pipe 51.

[0033] Specifically, such as Figure 4 As shown, one end of the feeding trough 56 is provided with an expansion groove 10, which is horn-shaped.

[0034] Specifically, such as Figure 4 As shown, a sealing cap 11 is provided at the top of the vertical tube 53.

[0035] During operation, the coolant enters the heat exchange tube 2 normally through the inlet pipe 3 and flows out through the outlet pipe 4, completing the heat dissipation cycle of the equipment in the machine room. When cleaning of the heat exchange tube 2 is required, the conveying assembly 58 starts working, and the sponge ball 57 falls from the vertical pipe 53 into the conveying pipe 52. The rotating conveying rod 581 moves in a spiral motion, and the conveying head 582 rotates together with the conveying rod 581. Because the conveying trough 583 is adapted to the moving conveying head 582, the moving conveying head 582 can effectively guide the sponge ball 57 to move along the conveying pipe 52, ensuring that the sponge ball 57 can smoothly enter the heat exchange tube 52. The cleaning pipe 51 reaches the feeding head 55, at which point the sponge ball 57 enters the feeding trough 56. The first electric push rod 54 is activated, and its output pushes the feeding head 55 downwards within the cleaning pipe 51. The feeding head 55 moves the sponge ball 57 inside it along with it. When the feeding head 55 reaches the bottom of the cleaning pipe 51, the sponge ball 57 follows the water flow into the heat exchange tube 2. The sealing rings 9 at both ends of the feeding head 55 are in close contact with the sidewall of the cleaning pipe 51, preventing coolant leakage during feeding and ensuring... The cleaning process proceeds smoothly because the expansion slot 10 at one end of the feeding trough 56 is flared, which allows the sponge ball 57 to be guided more smoothly into the feeding trough 56. After entering the heat exchange tube 2, the sponge ball 57 moves inside the heat exchange tube 2 with the flow of coolant. Due to the good adsorption and friction properties of the sponge ball 57, it can fully contact the inner wall of the heat exchange tube 2 during movement, adsorbing and scraping off scale, impurities, etc. on the inner wall, thereby cleaning the heat exchange tube 2. During the cleaning process, the coolant continues to flow, which not only carries away the dirt cleaned by the sponge ball 57, but also provides the power for the sponge ball 57 to move. In this way, the automatic cleaning mechanism 5 can clean the heat exchange tube 2 regularly or irregularly according to actual needs, and can clean it in time before the impurities inside the heat exchange tube 2 accumulate to the point of affecting the system performance. This effectively avoids the large accumulation of impurities inside the heat exchange tube 2, ensures the heat transfer efficiency of the heat exchange tube 2, and enables the water cooling heat dissipation system to always maintain high-efficiency heat dissipation performance, thereby ensuring the stable operation of the computer room equipment in a suitable temperature environment and extending the service life of the equipment.

[0036] Specifically, such as Figure 5 As shown, the collection and recycling mechanism 6 includes a cleaning tank 61 located in the middle of the outlet pipe 4. A filter screen 62 is provided on the inner wall of the cleaning tank 61. A horizontal pipe 63 is fixedly connected to the bottom of the cleaning tank 61. A cleaning port 64 is provided at one end of the horizontal pipe 63. A second electric push rod 65 is provided on the side wall of the horizontal pipe 63. A cleaning block 66 is fixedly connected to the output end of the second electric push rod 65. The cleaning block 66 is movably disposed inside the horizontal pipe 63. A cleaning groove 67 is provided on the side wall of the cleaning block 66. A cleaning assembly 68 is provided on the top of the cleaning tank 61.

[0037] Specifically, such as Figure 5As shown, the cleaning assembly 68 includes a top cover 681 disposed on the top of the cleaning tank 61, a cleaning rod 682 movably disposed in the middle of the top cover 681, a top plate 683 disposed on the top of the cleaning rod 682, a support spring 684 disposed between the top plate 683 and the top cover 681, and a cleaning brush 685 disposed at the bottom of the cleaning rod 682, the cleaning brush 685 being adapted to the filter screen cylinder 62.

[0038] During use, the coolant, carrying the sponge balls 57 and scale and impurities scraped from the heat exchange tube 2, flows out from the outlet pipe 4 of the heat exchange tube 2 and enters the cleaning tank 61 located in the middle of the outlet pipe 4. The filter screen 62 installed on the inner wall of the cleaning tank 61 blocks the sponge balls 57 and larger particles of impurities from passing through, while the coolant can pass smoothly through the filter screen 62. The sponge balls 57 and impurities are intercepted and retained inside the filter screen 62, thereby achieving the collection of the sponge balls 57 and impurities. The sponge balls 57 accumulated in the filter screen 62... Impurities gradually fall into the horizontal tube 63 at the bottom of the cleaning tank 61. When it is necessary to clean the sponge balls 57 and impurities in the horizontal tube 63, the second electric push rod 65 is activated. The second electric push rod 65 pushes the cleaning block 66 to move inside the horizontal tube 63. The cleaning block 66 has a cleaning groove 67 on its side wall. During the movement of the cleaning block 66, the cleaning groove 67 can collect and push the sponge balls 57 and impurities. When the cleaning block 66 moves to the cleaning port 64 at one end of the horizontal tube 63, the impurities in the cleaning groove 67 are collected and pushed. The sponge ball 57 and impurities are discharged from the cleaning tank 61 through the cleaning port 64, thus completing the cleaning and recycling of the sponge ball 57 and impurities. After cleaning, the second electric push rod 65 drives the cleaning block 66 to reset for the next cleaning operation. When the filter cylinder 62 needs to be cleaned, the top plate 683 is pressed down to compress the support spring 684. At this time, the cleaning rod 682 drives the cleaning brush 685 to move downward. The cleaning brush 685 brushes the inner wall of the filter cylinder 62, brushing off the impurities attached to the inner wall of the filter cylinder 62, preventing impurities from clogging the pores of the filter cylinder 62, and ensuring the filtration performance of the filter cylinder 62. In this way, the collection and recycling mechanism 6, through the cooperation of the cleaning tank 61 and the filter cylinder 62, can efficiently separate the sponge ball 57 and impurities carried in the coolant from the coolant, achieving precise collection of the sponge ball 57 and impurities, avoiding the spread of the sponge ball 57 and impurities throughout the water cooling system, reducing the potential damage of impurities to other components of the water cooling system, and ensuring the stable operation of the water cooling system.

[0039] By adopting the above technical solution, the problem that the existing computer room water cooling device cannot automatically clean the heat exchange tube 2 is solved. During long-term use, the heat exchange tube 2 is prone to residual or adhering impurities in the water, which reduces the heat exchange efficiency of the heat exchange tube 2.

[0040] Working Principle: In use, the coolant first enters the heat exchange tube 2 normally through the inlet pipe 3 and flows out through the outlet pipe 4, completing the heat dissipation cycle of the equipment in the machine room. When cleaning of the heat exchange tube 2 is required, the first electric push rod 54 is activated. The output end of the first electric push rod 54 pushes the feeding head 55 downwards within the cleaning tube 51. The feeding head 55 moves the sponge balls 57 inside it along with the water flow. When the feeding head 55 reaches the bottom of the cleaning tube 51, the sponge balls 57 follow the water flow into the heat exchange tube 2. After entering the heat exchange tube 2, the sponge balls 57 move within the heat exchange tube 2 with the flow of coolant. Due to the good adsorption and friction properties of the sponge balls 57, during the movement, the sponge balls 57 can fully contact the inner wall of the heat exchange tube 2, adsorbing and scraping away scale, impurities, etc., on the inner wall. This process cleans the heat exchange tube 2. The coolant, carrying the sponge balls 57 and the scale and impurities scraped off inside the heat exchange tube 2, flows out from the outlet pipe 4 of the heat exchange tube 2 and enters the cleaning tank 61 located in the middle of the outlet pipe 4. The filter screen 62 installed on the inner wall of the cleaning tank 61 blocks the sponge balls 57 and larger particles of impurities from passing through, while the coolant can pass smoothly through the filter screen 62. The sponge balls 57 and impurities are intercepted and left inside the filter screen 62, thus achieving the collection of the sponge balls 57 and impurities. The sponge balls 57 and impurities accumulated in the filter screen 62 will gradually fall into the horizontal pipe 63 at the bottom of the cleaning tank 61.
