Description

Technical Field

[0001] This utility model relates to the field of fans, and more specifically, to a computer fan with a self-cleaning function. Background Technology

[0002] The electronic components inside a computer typically generate heat during operation, which can raise their temperature and affect their normal operation. Therefore, it is necessary to install a heat dissipation device to ensure that the components operate normally at an appropriate temperature.

[0003] A search revealed an existing patent (publication number: CN1499335A) that discloses a computer cooling fan, including a housing and a heat sink. The heat sink is encapsulated in the housing, which is fixed to the computer chassis. The housing has an oblong hole through which the heat sink is fixed to the housing using bolts. The housing also has an oblong hole on its end face corresponding to the chassis, through which the cooling device is fixed to the chassis using bolts. The cooling device can be adjusted according to the position of the components. Therefore, this cooling device is suitable for different computer models. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Existing computer fans often only have a single heat dissipation fin or fan, resulting in limited heat dissipation. At the same time, the air intake grille of the fan will accumulate a lot of dust during long-term use, which will affect the air intake efficiency. Currently, computer fans often need to be manually disassembled to clean the air intake grille, and do not have an automatic cleaning function.

[0005] Therefore, a computer fan with a self-cleaning function is proposed to address the above problems. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a computer fan with a self-cleaning function, comprising a first heat dissipation fin, a first fan disposed on one side of the first heat dissipation fin, the first fan being connected to the first heat dissipation fin by bolts, a second heat dissipation fin being connected to the side of the first fan away from the first heat dissipation fin, a heat-conducting seat being connected to the side of the first fan by fixing bolts, heat pipes being arranged and connected along the edges of the heat-conducting seat, the heat pipes being disposed through the middle of the first and second heat dissipation fins, a second fan being disposed on the side of the second heat dissipation fin away from the first fan, sound-absorbing pads being disposed along the edges of both the second and first fans, a fixing frame being connected to the side of the second fan away from the second heat dissipation fin by bolts, and an air intake grille being arranged in the middle of the fixing frame.

[0008] Preferably, a threaded rod is connected to one side of the fixed frame via a bearing, and a movable block is threadedly connected to the outer wall of the middle part of the threaded rod. A strip groove is provided on the inner wall of one side of the fixed frame, and a slider is connected to the outer wall of the movable block near the strip groove. The slider is embedded in the strip groove.

[0009] Preferably, a cleaning strip is connected to the side of the moving block away from the slider, and a through groove is arranged in the middle of the cleaning strip, with multiple sets of air intake grilles passing through the through groove.

[0010] Preferably, the inner wall of the through groove is provided with a cleaning cotton block, which abuts against the outer wall of the air intake grille.

[0011] Preferably, a servo motor is provided on the top side of the fixed frame. The output end of the servo motor is connected to the threaded rod. The servo motor drives the threaded rod to rotate. The rotation of the threaded rod drives the moving block to move up and down and translate. The movement of the moving block drives the slider and the cleaning strip to move synchronously.

[0012] Preferably, a temperature sensor is provided on one side of both the first and second heat dissipation fins, and a controller is provided on one side of the heat conduction base. The controller is connected to the temperature sensor, the first fan, and the second fan via wires.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. Compared with the existing technology, this computer fan with self-cleaning function improves heat dissipation efficiency by setting two sets of heat conduction mechanisms, namely No. 1 heat dissipation fins and No. 2 heat dissipation fins, and two sets of cooling fans, namely No. 1 fan and No. 2 fan. While dissipating heat from No. 2 heat dissipation fins, No. 2 fan accelerates the airflow into No. 1 fan, thereby making the airflow blown out by No. 1 fan stronger and saving the power consumption of No. 1 fan.

[0015] 2. Compared with the existing technology, this computer fan with self-cleaning function is driven by a servo motor to rotate a threaded rod. The rotation of the threaded rod drives a moving block to move up and down and translate. The movement of the moving block drives the slider and the cleaning strip to move synchronously. The cleaning cotton block can move synchronously with the movement of the cleaning strip. By moving the cleaning cotton block, the dust on the outer wall of the air intake grille can be cleaned and removed, thereby improving the cleanliness of the air intake grille and preventing the air intake efficiency of the fan from being affected by the accumulation of dust in the air intake grille, thus improving the fan's heat dissipation efficiency.

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.

[0022] Example 1

[0023] As attached Figures 1 to 3The computer fan shown includes a first heat sink 1, a first fan 2 on one side of the first heat sink 1, the first fan 2 and the first heat sink 1 are connected by bolts, a second heat sink 3 is connected to the side of the first fan 2 away from the first heat sink 1, a heat conduction seat 4 is connected to the side of the first fan 2 by fixing bolts 5, heat pipes 6 are arranged and connected along the edge of the heat conduction seat 4, the heat pipes 6 are arranged through the middle of the first heat sink 1 and the second heat sink 3, a second fan 7 is arranged on the side of the second heat sink 3 away from the first fan 2, sound-absorbing pads 8 are arranged at the edge of the second fan 7 and the first fan 2, a fixing frame 9 is connected to the side of the second fan 7 away from the second heat sink 3 by bolts, and an air intake grille 10 is arranged in the middle of the fixing frame 9.

[0024] Specifically: By installing the heat-conducting base 4 at the connection point with the computer motherboard, heat can be conducted to the heat pipe 6 through the heat-conducting base 4. Both the first set of heat dissipation fins 1 and the second set of heat dissipation fins 3 are in contact with the heat pipe 6, thereby increasing the surface area for heat dissipation and improving the contact opportunity between heat and air, thus accelerating heat transfer and improving heat dissipation efficiency. The first fan 2 and the second fan 7 blow air onto the surfaces of the first set of heat dissipation fins 1 and the second set of heat dissipation fins 3 respectively. When the high-speed airflow passes over the heat dissipation fins, it carries away the heat transferred from the heat pipe 6, achieving effective heat dissipation. The system incorporates two sets of heat conduction mechanisms, namely heat dissipation fin 1 and heat dissipation fin 3, along with two sets of cooling fans, namely fan 2 and fan 7, thereby improving heat dissipation efficiency. While dissipating heat from heat dissipation fin 3, fan 7 accelerates the airflow into fan 2, resulting in a stronger airflow from fan 2 and saving power consumption. Sound-absorbing pad 8 reduces fan noise, fixed frame 9 provides fixation, and air intake grille 10 controls and guides airflow into the fan for more effective heat dissipation.

[0025] Example 2

[0026] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

A slider 14 is connected to the outer wall of the movable block 12 near the strip groove 13. The slider 14 is embedded in the strip groove 13. Furthermore, the threaded rod 11 can rotate within the fixed frame 9. The rotation of the threaded rod 11 can drive the movable block 12 to perform translational movement. The slider 14 slides within the strip groove 13, thereby limiting the movement of the movable block 12.

[0028] In a preferred embodiment, a cleaning strip 15 is connected to the side of the movable block 12 away from the slider 14. A through groove 16 is arranged in the middle of the cleaning strip 15, and multiple sets of air intake grilles 10 pass through the through groove 16. Furthermore, the cleaning strip 15 can clean the air intake grilles 10 to prevent dust from adhering to the air intake grilles 10 during long-term use and affecting the air intake efficiency.

[0029] In a preferred embodiment, the inner wall of the through groove 16 is provided with a cleaning cotton block 20, which abuts against the outer wall of the air intake grille 10; furthermore, the cleaning cotton block 20 can move synchronously with the movement of the cleaning strip 15, and the dust on the outer wall of the air intake grille 10 can be cleaned and removed by the cleaning cotton block 20.

[0030] In a preferred embodiment, a servo motor 17 is provided on one side of the top of the fixed frame 9. The output end of the servo motor 17 is connected to the threaded rod 11. The servo motor 17 drives the threaded rod 11 to rotate, and the rotation of the threaded rod 11 drives the moving block 12 to move up and down and translate. The movement of the moving block 12 drives the slider 14 and the cleaning strip 15 to move synchronously. Furthermore, the servo motor 17 drives the threaded rod 11 to rotate, and the rotation of the threaded rod 11 drives the moving block 12 to move up and down and translate. The movement of the moving block 12 drives the slider 14 and the cleaning strip 15 to move synchronously. The cleaning cotton block 20 can move synchronously with the movement of the cleaning strip 15. By moving the cleaning cotton block 20, the dust on the outer wall of the air intake grille 10 can be cleaned and removed, thereby improving the cleanliness of the air intake grille 10 and preventing the air intake efficiency of the fan from being affected by the accumulation of dust in the air intake grille 10, thus improving the fan's heat dissipation efficiency.

[0031] In a preferred embodiment, a temperature sensor 18 is provided on one side of both the first heat dissipation fin 1 and the second heat dissipation fin 3, and a controller 19 is provided on one side of the heat conduction base 4. The controller 19 is connected to the temperature sensor 18, the first fan 2, and the second fan 7 via wires. Furthermore, the temperature sensor 18 can detect the current temperature. When a high temperature is detected, a signal can be transmitted to the controller 19. The controller 19 controls the start of the first fan 2 and the second fan 7 to perform heat dissipation. Different temperatures detected by the temperature sensor 18 allow the controller 19 to adjust the power of the first fan 2 and the second fan 7 to achieve energy saving.

[0032] The working process of this utility model is as follows: First, the heat-conducting base 4 is installed at the connection point with the computer motherboard. The heat-conducting base 4 can conduct heat to the heat pipe 6. Both the first heat dissipation fin 1 and the second heat dissipation fin 3 are connected to the heat pipe 6, thereby increasing the surface area of ​​heat dissipation and improving the contact opportunity between heat and air, thus accelerating heat transfer and improving heat dissipation efficiency. The first fan 2 and the second fan 7 blow air onto the surfaces of the first heat dissipation fin 1 and the second heat dissipation fin 3 respectively. The high-speed airflow over the heat dissipation surface... When the fins are in place, they carry away the heat transferred from the heat pipe 6, achieving effective heat dissipation. By setting up two sets of heat conduction mechanisms (one set of heat dissipation fins 1 and 3) and two sets of cooling fans (one set of fans 2 and 7), the heat dissipation efficiency is improved. While cooling the second heat dissipation fin 3, the second fan 7 accelerates the airflow into the first fan 2, making the airflow from the first fan 2 stronger and saving its power consumption. The sound-absorbing pad 8 reduces fan noise. The fixing frame 9... The air intake grille 10 serves a fixing function and controls and guides airflow into the fan for more effective heat dissipation. A servo motor 17 drives a threaded rod 11 to rotate, which in turn moves a moving block 12 up, down, and horizontally. The moving block 12 then moves a slider 14 and a cleaning strip 15 synchronously. The cleaning cotton block 20 moves synchronously with the cleaning strip 15, cleaning dust from the outer wall of the air intake grille 10, thus improving its cleanliness and preventing dust accumulation from affecting the fan's air intake efficiency, thereby improving the fan's heat dissipation efficiency. When a high temperature is detected, a signal is transmitted to the controller 19, which then activates the first fan 2 and the second fan 7 for heat dissipation. Different temperatures detected by the temperature sensor 18 allow the controller 19 to adjust the power of the first fan 2 and the second fan 7, achieving energy savings. This is the working principle of this self-cleaning computer fan.
