Description

Technical Field

[0001] This utility model belongs to the field of laptop cooling technology, and in particular relates to a high-efficiency, low-noise fan for laptops. Background Technology

[0002] With advancements in technology and increasing user demands for computing performance, the operating frequencies and integration levels of key components such as CPUs and GPUs within laptops are constantly increasing. This leads to greater heat generation, and efficient heat dissipation is crucial for maintaining the stable operation of these electronic components. Poor heat dissipation can cause system overheating, automatic frequency throttling, or even shutdown, severely impacting user experience and hardware lifespan.

[0003] Traditional laptop cooling solutions typically rely on small axial fans in conjunction with heat sinks or heat pipes to dissipate heat. However, traditional fans have some significant limitations: ordinary fan setups may not provide sufficient airflow to meet the cooling needs of high-performance hardware; to increase airflow, fan speed needs to be increased, but this results in greater operating noise, affecting the user experience; and some traditional fans lack the ability to intelligently adjust their speed based on temperature changes, failing to achieve optimal energy efficiency.

[0004] To address these issues, we provide a high-efficiency, low-noise fan for laptops. Utility Model Content

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

[0006] This utility model is a high-efficiency, low-noise fan for laptops, including a fan body. The fan body includes a frame, a counterweight fixed to the periphery of the frame, a splitter plate fixed to the front of the frame, a base fixed to the back of the frame via a support arm, fan blades connected to the output shaft of the base, and a guide strip disposed on the surface of the fan blades.

[0007] The present invention is further provided with mounting holes at the corners of the frame and triangular rubber pads at the ends of the frame.

[0008] The present invention is further configured such that the flow divider covers the outside of the fan blade, and the flow divider is provided with a plurality of triangular grooves around it.

[0009] The present invention is further configured such that adjacent guide strips are spaced apart to form a guide channel, and the guide strips and fan blades are made of carbon fiber composite material.

[0010] The present invention is further configured such that the base has a built-in brushless DC motor and a controller, and the controller is connected to temperature sensors installed on key heat-generating components such as the CPU and GPU.

[0011] The present invention is further configured such that the surface of the diverter plate is coated with multiple layers of sound-absorbing material.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model enhances the directionality and speed of airflow by using fan blades and guide strips made of carbon fiber composite materials, as well as optimized airflow path settings (such as triangular grooves on the splitter plate), thereby improving heat dissipation efficiency. This helps ensure that the laptop maintains stable operation under high-performance workloads and avoids performance degradation or hardware damage caused by overheating.

[0014] 2. This utility model effectively absorbs the noise generated when the fan is running by coating the surface of the distributor plate with multiple layers of sound-absorbing material. At the same time, the setting of the counterweight reduces the vibration and noise caused by rotational imbalance. These features work together to provide users with a quieter operating environment, which is especially suitable for applications that require long-term computer use or are sensitive to noise.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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.

[0023] Example

[0024] Please see Figure 1-3 This utility model is a high-efficiency, low-noise fan for laptops, including a fan body 100. The fan body 100 includes a frame 101, a counterweight 102 fixed to the periphery of the frame 101, a splitter plate 103 fixed to the front of the frame 101, a base 106 fixed to the back of the frame 101 via a support arm 110, fan blades 108 connected to the output shaft of the base 106, and guide strips 109 disposed on the surface of the fan blades 108. Adjacent guide strips 109 form a guide channel at intervals. The guide strips 109 and the fan blades 108 are made of carbon fiber composite material.

[0025] Specifically, the diverter plate 103 covers the outside of the fan blade 108, and the diverter plate 103 is surrounded by several triangular grooves. The surface of the diverter plate 103 is coated with multiple layers of sound-absorbing material.

[0026] Furthermore, the base 106 has a built-in brushless DC motor and controller, and the controller is connected to temperature sensors installed on key heat-generating components such as the CPU and GPU.

[0027] Furthermore, mounting holes 104 are provided at the corners of the frame 101, and triangular rubber pads 105 are provided at the ends of the frame 101.

[0028] The frame 101 serves as the basic framework of the entire fan structure. It not only provides mechanical support but also protects the internal components. The mounting holes 104 on it ensure that the fan body 100 can be securely fixed inside the laptop, while the triangular rubber pads 105 at the ends help reduce the transmission of vibration to the computer casing, thereby reducing operating noise and protecting the internal components of the computer from unnecessary wear.

[0029] The counterweight 102 is used to balance the centrifugal force generated when the fan blade 108 rotates, and a reasonable counterweight distribution can significantly reduce vibration and noise caused by imbalance, while improving the service life of the fan body 100.

[0030] The airflow path is optimized by the surrounding triangular grooves of the splitter plate 103, so that the air blown out by the fan body 100 can be more evenly distributed. The multi-layer sound-absorbing material coated on its surface can not only absorb the sound generated by the operation of the fan, but also reduce wind noise, providing users with a quieter operating environment.

[0031] The frame 106 integrates a brushless DC motor. This type of motor has no brush contact, which reduces friction loss and maintenance requirements, and also reduces electromagnetic interference. The built-in controller can intelligently adjust the fan speed according to the data from the temperature sensor to achieve precise temperature control, ensuring heat dissipation while also taking energy saving into account.

[0032] The fan blades 108 and the air guide strips 109 are made of carbon fiber composite material, which has a high strength-to-weight ratio, reducing the overall weight without sacrificing strength. The air guide strips 109 increase the airflow guidance, and the spacing between adjacent air guide strips 109 forms an efficient airflow channel, enhancing the speed and direction control of airflow and improving heat dissipation efficiency.

[0033] Working principle

[0034] When a laptop is in operation, key components such as the CPU and GPU generate heat. Temperature sensors monitor temperature changes in these areas in real time and send this information to the controller inside the fan. The controller then adjusts the fan blade speed accordingly to maintain an ideal temperature range. Specifically:

[0035] Under low temperature conditions, the fan blade 108 may remain stationary or operate at a very low speed to save power; when the temperature rises to a certain threshold, the fan blade 108 begins to accelerate, increasing the airflow to carry away more heat; if the temperature continues to rise, the fan blade 108 will accelerate further until it reaches the maximum safe speed to ensure that the electronic components do not overheat and be damaged.

[0036] In addition, the special design of the splitter plate 103 and the presence of the guide strip 109 help improve airflow characteristics, making the cooling process more efficient and stable. At the same time, by using a brushless DC motor and sound-absorbing materials, the fan body 100 can maintain a relatively quiet working environment while ensuring good heat dissipation performance.
