Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology, and in particular to a split-type laptop fan heat sink. Background Technology

[0002] When a laptop is in use, it generates heat. The cooling fan built into the laptop is often insufficient to dissipate the heat, so a fan cooler is usually placed at the bottom of the laptop. The airflow blown out by the fan cooler dissipates heat from the laptop. The fan cooler mainly consists of a casing, a cross-flow fan, a battery, and a motor. When the fan cooler is in use, the motor drives the cross-flow fan to rotate. As the cross-flow fan rotates, airflow enters from the top of the casing, passes through the cross-flow fan, and is blown out from the side of the casing onto the bottom of the laptop, thus dissipating heat from the laptop.

[0003] During use, the fan cooler accelerates airflow, which achieves heat dissipation for the laptop. However, during the heat dissipation process, dust in the air will enter the laptop with the airflow and adhere to the cooling fan. This will increase the fan load, causing the fan speed to drop or even make noise, thereby reducing the heat dissipation efficiency and potentially causing the laptop to overheat. Therefore, this application provides a split-type laptop fan cooler to meet the needs. Utility Model Content

[0004] This invention provides a split-type laptop fan cooler to solve the problem of dust entering the laptop and causing it to overheat.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A split-type laptop fan cooler includes a cooling fan and two brackets. The cooling fan has an air inlet on its top and an air outlet on its side. The two brackets are mounted on the side of the cooling fan and located at the air outlet. The cooler also includes:

[0007] The dust removal mechanism includes a cylinder installed at the air inlet of a cooling fan. A crossbeam is fixed to the inner wall of the cylinder near the top center. Arc-shaped adsorption plates are symmetrically installed on the inner wall of the cylinder. The surface of the arc-shaped adsorption plates is coated with an adhesive layer. A flexible connecting strip is fixed to the side of the crossbeam. A baffle is fixed to the side of the flexible connecting strip. A flow channel is formed between the baffle and the arc-shaped adsorption plate. An adjustment component is provided on the crossbeam. The adjustment component is used to adjust the tilt angle of the baffle. As the baffle tilts downward, the opening of the flow channel gradually increases.

[0008] Preferably, a positioning frame is fixed at the top air inlet of the cooling fan, and an arc-shaped guide surface is provided at the opening of the positioning frame. In use, the cylinder is placed inside the positioning frame and located at the top of the cooling fan.

[0009] Preferably, a magnetic ring one is fixed to the inner wall of the positioning frame, and a magnetic ring two is fixed to the bottom of the cylinder. In use, the magnetic ring two is magnetically attracted to the top of the magnetic ring one.

[0010] Preferably, the adjusting assembly includes a screw threaded through the middle of the crossbeam, a support plate fixed to the bottom of the screw, and the support plate supporting the bottom of the baffle. When adjusting the baffle, rotating the screw causes the support plate to rotate the baffle downwards.

[0011] Preferably, a handwheel is fixed to the top of the screw, and anti-slip stripes are provided on the side of the handwheel.

[0012] Preferably, the top of the arc-shaped adsorption plate is integrally formed with an upper baffle, and when the cooling fan is not in use, the baffle is horizontally attached to the bottom of the upper baffle.

[0013] Preferably, the surface of the arc-shaped adsorption plate is provided with a plurality of protrusions, which are arc-shaped.

[0014] Preferably, a cleaning groove is provided at the top of the cylinder, and when the cooling fan is not in use, the top of the baffle and the bottom of the inner wall of the cleaning groove are in the same plane.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above solution, by setting up a cylinder, baffle, arc-shaped adsorption plate, and adjustment components, the airflow passes through the channel between the baffle and the arc-shaped adsorption plate during use. When the airflow passes through the arc-shaped adsorption plate, the adhesive layer on its surface directly captures dust in the air, which not only prevents dust from adhering to the inside of the cooling fan, but also blocks dust from entering the laptop body, avoiding the impact of dust on the laptop's heat dissipation efficiency. In addition, when it is necessary to increase the air intake, by rotating the screw in the adjustment component, the screw will drive the support plate to move downward, and the baffle will tilt downward under its own gravity, thereby increasing the opening of the airflow channel. Conversely, if there is a lot of dust in the environment, the opening of the airflow channel can be reduced to improve the dust capture rate; if the laptop has a high load and the heat dissipation demand increases, the opening of the airflow channel can be increased to increase the air intake, meeting the usage needs in different scenarios.

[0017] By adding protrusions, the contact area between the air and the arc-shaped adsorption plate can be increased, and the contact time between the air and the arc-shaped adsorption plate can be extended, thereby improving the dust collection efficiency.

[0018] By setting up an upper baffle, when the cooling fan is not in use, the support plate moves the baffle to fit against the bottom of the upper baffle, blocking the flow channel. At this time, the baffle is set horizontally to prevent dust from entering the cooling fan from the flow channel.

[0019] By setting up a cleaning slot, when the cooling fan has been idle for a long time, dust will fall onto the top of the baffle. Before use, the dust can be wiped away towards the cleaning slot and discharged from there. The cleaning slot prevents the cylinder from blocking the dust discharge and improves the convenience of cleaning operations.

[0020] By setting up a positioning frame, magnetic ring one, and magnetic ring two, the positioning frame can position the cylinder, making it easy to place the cylinder at the air inlet of the cooling fan and preventing horizontal displacement of the cylinder during use. Secondly, the magnetic force of magnetic ring one and magnetic ring two can increase the connection strength between the cylinder and the cooling fan, and the disassembly and installation of the cylinder are very convenient.

[0027] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of this utility model. However, this is only for illustrative purposes and is not intended to limit this utility model to the specific structure, device and environment. According to specific needs, those skilled in the art can adjust or modify these devices and environments, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0028] The present invention provides a split-type laptop fan cooler in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0029] like Figures 1-5 As shown, an embodiment of this utility model provides a split-type laptop fan cooler, including a cooling fan 1 and two brackets 2. The cooling fan 1 has an air inlet on its top and an air outlet on its side. The two brackets 2 are mounted on the side of the cooling fan 1 and located at the air outlet. The device also includes:

[0030] The dust removal mechanism 3 includes a cylindrical body 6 installed at the air inlet of the cooling fan 1. A crossbeam 8 is fixed to the inner wall of the cylindrical body 6 near the top center. Arc-shaped adsorption plates 15 are symmetrically installed on the inner wall of the cylindrical body 6. The surface of the arc-shaped adsorption plates 15 is coated with an adhesive layer. A flexible connecting strip 9 is fixed to the side of the crossbeam 8, and a baffle 10 is fixed to the side of the flexible connecting strip 9. A flow channel is formed between the baffle 10 and the arc-shaped adsorption plates 15. An adjustment component is provided on the crossbeam 8 to adjust the tilt angle of the baffle 10. As the baffle 10 tilts downward, the opening of the flow channel gradually increases. The cooling fan 1 draws in air through the air inlet and discharges air through the air outlet, thus providing airflow for the pen. The laptop cooling system includes a stand 2 to support the laptop and ensure efficient heat dissipation, a cylinder 6 to provide installation space for dust removal components, and an adhesive layer on the surface of the arc-shaped adsorption plate 15, typically a dustproof adhesive that can be replaced periodically. This layer captures dust from the air, preventing it from accumulating inside the cooling fan 1 or entering the laptop with the airflow. The flexible connecting strap 9 can deform flexibly with the baffle 10 to ensure a sealed flow channel and prevent unfiltered air from directly entering the cooling fan 1. The adjustment component allows for adjustment of the flow channel opening size by adjusting the tilt angle of the baffle 10: the opening is reduced when there is a lot of dust and enlarged when the heat dissipation demand is high, balancing dust removal and heat dissipation to adapt to different usage scenarios.

[0031] like Figure 2 As shown in this embodiment, a positioning frame 4 is fixed at the top air inlet of the cooling fan 1. An arc-shaped guide surface is provided at the opening of the positioning frame 4. In use, the cylinder 6 is placed inside the positioning frame 4 and located at the top of the cooling fan 1. The positioning frame 4 fixes the cylinder 6 directly above the air inlet by physical limiting, which prevents the cylinder 6 from shifting due to vibration when the fan is working, and ensures that all intake air is filtered through the flow channel. The arc-shaped guide surface can guide the cylinder 6 to be quickly put into the positioning frame 4, shortening the installation time and improving the ease of operation.

[0032] like Figures 2-4As shown in this embodiment, a magnetic ring 5 is fixed to the inner wall of the positioning frame 4, and a magnetic ring 7 is fixed to the bottom of the cylinder 6. In use, the magnetic ring 7 is magnetically attracted to the top of the magnetic ring 5, and the magnetic ring 5 and the magnetic ring 7 are fixed by magnetic attraction, which further enhances the connection strength between the cylinder 6 and the positioning frame 4.

[0033] like Figure 4 As shown in this embodiment, the adjusting component includes a screw 13 threaded through the middle of the crossbeam 8, and a support plate 14 fixed to the bottom of the screw 13. The support plate 14 is supported on the bottom of the baffle 10. When adjusting the baffle 10, the screw 13 is rotated, and the support plate 14 drives the baffle 10 to rotate downward. The screw 13 and the crossbeam 8 are threaded together to achieve lifting and lowering. The force is transmitted through the support plate 14 to drive the baffle 10 to smoothly adjust the tilt angle.

[0034] like Figure 4 As shown in this embodiment, a handwheel 12 is fixed to the top of the screw 13. The side of the handwheel 12 is provided with anti-slip stripes. The handwheel 12 increases the force application radius of the screw 13, allowing the operator to easily rotate the screw 13.

[0035] like Figure 5 As shown in this embodiment, the top of the arc-shaped adsorption plate 15 is integrally formed with an upper baffle 17. When the cooling fan 1 is not in use, the baffle 10 is horizontally attached to the bottom of the upper baffle 17. The upper baffle 17 and the baffle 10 cooperate to form a "sealed structure". When the fan is not in use, the baffle 10 is horizontally attached to the upper baffle 17, completely blocking the flow channel and preventing dust in the air from entering the interior of the cooling fan 1 or the laptop through the air inlet, ensuring that the interior of the cooling fan 1 is clean. The upper baffle 17 can also limit the maximum lifting angle of the baffle 10, preventing the baffle 10 from being overly tilted during adjustment, which would cause the flexible connecting strip 9 to tear, protect the dust removal mechanism 3 components, and extend their service life.

[0036] like Figure 5 As shown in this embodiment, the surface of the arc-shaped adsorption plate 15 is provided with a number of protrusions 16. The protrusions 16 are arc-shaped. The arc-shaped protrusions 16 can increase the contact area between the air and the arc-shaped adsorption plate 15, prolong the residence time of the air in the flow channel, and make the adhesive layer capture dust more fully, thereby improving the capture effect.

[0037] like Figure 4 As shown in this embodiment, a cleaning groove 11 is provided on the top of the cylinder 6. When the cooling fan 1 is not in use, the top of the baffle 10 and the bottom of the inner wall of the cleaning groove 11 are in the same plane. The cleaning groove 11 provides a channel for cleaning dust on the top of the baffle 10. When the fan is not in use, the baffle 10 and the bottom of the cleaning groove 11 are flush. The operator can use a brush or cloth to wipe along the baffle 10, and finally the dust is discharged from the cleaning groove 11.

[0038] Working principle: Before use, align the magnetic ring 2 7 at the bottom of the cylinder 6 with the magnetic ring 1 5 inside the positioning frame 4 at the top air inlet of the cooling fan 1. With the help of the arc-shaped guide surface at the opening of the positioning frame 4, the magnetic ring 2 7 is magnetically attracted to the top of the magnetic ring 1 5, thus completing the installation of the cylinder 6 and the cooling fan 1.

[0039] Adjust the tilt angle of the baffle 10 according to the usage environment. If the environment is dusty, turn the handwheel 12 to drive the screw 13 to move upward, and the support plate 14 will move upward accordingly. The baffle 10 will rotate upward under the action of the flexible connecting belt 9, and the flow channel opening will decrease. If it is necessary to increase the air intake, turn the handwheel 12 in the opposite direction, and the screw 13 will drive the support plate 14 to move downward. The baffle 10 will tilt downward, and the flow channel opening will increase. The flow channel is formed by the baffle 10 and the arc-shaped adsorption plate 15.

[0040] When the cooling fan 1 is turned on, air enters from the top of the cylinder 6 and flows along the flow channel through the arc-shaped adsorption plate 15. The protrusion 16 increases the contact area, and the adhesive layer captures dust in the air. The airflow enters the cooling fan 1 through the air inlet and is then discharged from the side air outlet to cool the laptop. During the process, the positioning frame 4 prevents the cylinder 6 from shifting horizontally.

[0041] If the cooling fan 1 is temporarily stopped, turn the handwheel 12 to make the baffle 10 fit horizontally against the bottom of the upper baffle 17 on the top of the arc-shaped adsorption plate 15, blocking the flow channel and preventing dust from entering the cooling fan 1.

[0042] If the baffle 10 has not been used for a long time, dust may accumulate on the top of the baffle 10. Wipe the top of the baffle 10 in the direction of the cleaning groove 11 on the top of the cylinder 6, and the dust will be discharged from the cleaning groove 11. If there is a lot of dust on the adhesive layer of the arc-shaped adsorption plate 15, separate the magnetic ring 15 and the magnetic ring 27, remove the cylinder 6, unscrew the screws on the side of the cylinder 6, rotate the screw 13, and the screw 13 will drive the support plate 14 to move down. The baffle 10 will tilt downwards, and the arc-shaped adsorption plate 15 can be removed. Replace the new arc-shaped adsorption plate 15 and fix the new arc-shaped adsorption plate 15 inside the cylinder 6 with screws to complete the replacement.

[0043] After replacement, reinstall the cylinder 6 in the positioning frame 4, adjust the angle of the baffle 10 as needed, and the cooling fan 1 can be started again.

[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
