Description

Technical Field

[0001] The utility model relates to the technical field of computer cooling fans, and more specifically to an anti-blocking computer cooling fan. Background Art

[0002] A cooling fan needs to be installed inside the computer mainframe case to dissipate heat for a series of devices such as the computer's motherboard, CPU, and graphics card. When the cooling fan is used for a long time, a lot of dust will be attached to it, which seriously affects the cooling performance of the cooling fan.

[0003] After searching, the utility model patent with announcement number CN219695722U discloses an anti-blocking computer cooling fan, including a cooling fan base, wherein the left and right sides of the top of the cooling fan base are fixedly connected with an inverted L-shaped clamping plate, the inner top end of the inverted L-shaped clamping plate is fixedly connected with a telescopic sleeve, the outer side of the telescopic sleeve is sleeved with a compression spring, the bottom of the telescopic sleeve is fixedly connected with a buckle, and a dustproof mechanism is arranged between the inverted L-shaped clamping plates. Through the provided dustproof mechanism, the cooling fan base is installed on the inner wall inside the computer host for heat dissipation. When the user performs maintenance work on the computer host, the side sliding cover of the host is opened to expose the cooling fan base, and the dustproof plate can be taken out for cleaning by grabbing the hand pull block. There is no need to remove the entire fan body, which brings convenience to the user. At the same time, it can also increase the service life of the cooling fan and prevent the cooling fan from being blocked.

[0004] However, the above patents still have the following shortcomings: it is not convenient to clean the dust filtered on the dustproof plate by yourself during use; and when the water in the water cooling pipe is used to cool the inside of the chassis, the water in the water cooling pipe contains impurities such as scale after long-term use, and the impurities easily cause the water cooling pipe to be blocked. For this reason, we propose an anti-blocking computer cooling fan. Utility Model Content

[0029] For details, please refer to Figure 1 , Figure 2 and Figure 4The water cooling mechanism 2 includes a plurality of fixing seats 13 fixedly connected to the inner wall of the mounting frame 1, a heat exchange tube 14 is fixedly sleeved on the plurality of fixing seats 13, a filter box 15 is fixedly sleeved at one end of the heat exchange tube 14, a sealing door 18 is hinged on the outer side of the filter box 15, a filter cotton 17 is placed on the inner wall of the filter box 15, and a water inlet pipe 16 is fixedly sleeved at the end of the filter box 15.

[0030] In this embodiment, the filter cotton 17 can be replaced by opening the sealing door 18 , and the impurities filtered out of the filter cotton 17 can also be cleaned.

[0031] For details, please refer to Figure 3 Two slide bars 21 are fixedly sleeved between the mounting seat 9 and the collecting box 8, and the slide bars 21 and the scraper 11 are movably sleeved.

[0032] In this embodiment, the scraper 11 is limited by the cooperation between the scraper 11 and the slide rod 21 , so that the scraper 11 can only move along the axial direction of the reciprocating screw 10 .

[0033] For details, please refer to Figure 2 Two air exhaust holes 24 are provided on the back of the installation frame 1 , and an air inlet slot 23 is provided on the front of the installation frame 1 .

[0034] In this embodiment, the cooperation between the air inlet slot 23 and the air exhaust hole 24 facilitates the fan body 3 to exhaust air.

[0040] In this embodiment, it is ensured that the filter cotton 17 can completely filter the cooling water passing through the inner cavity of the filter box 15 .

[0041] Working principle: when the computer is running, the fan body 3 is started so that the external air passes through the filter 7 and the mounting frame 1 and blows into the inside of the chassis, thereby taking away the heat inside the chassis. At the same time, the filter 7 is used to filter out dust and other impurities in the air to prevent dust from entering the chassis. In addition, when the weather is hot, the water required for water cooling is introduced into the filter box 15 from the water inlet pipe 16 by a water pump, and the impurities in the water flowing through the filter box 15 are filtered by the filter cotton 17. The filtered water enters the heat exchange tube 14, and the water in the heat exchange tube 14 is used to exchange heat with the air passing through the mounting frame 1 to achieve air cooling, ensuring that the temperature of the wind entering the chassis for heat dissipation is low. In addition, the other end of the heat exchange tube 14 guides the water after heat exchange back to the water cooling tank;

[0042] When the computer stops running, the computer host controls the servo motor 12 to run for a fixed time, and uses the servo motor 12 to drive the reciprocating screw 10 to rotate a fixed number of circles, and uses the cooperation between the reciprocating screw 10 and the scraper 11 to drive the scraper 11 to move back and forth up and down for a cycle. When the scraper 11 moves downward, the inner side of the scraper 11 pushes the dust filtered from the filter 7 into the collection box 8 for collection, so as to avoid clogging of the filter 7 and ensure the filtering effect of the filter 7. When a lot of dust is collected in the collection box 8, the card plate 6 and the collection box 8 are directly pulled out from the card seat 4, so as to clean the dust collected in the collection box 8.

[0043] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the utility model according to the technical solution and improved ideas of the utility model, which should be included in the protection scope of the utility model.
