Description

Technical Field

[0001] This utility model belongs to the field of notebook heat dissipation technology, and in particular relates to a notebook extended heat sink. Background Technology

[0002] External laptop coolers, also known as laptop extension coolers, are external devices designed to compensate for the limitations of a laptop's built-in cooling system. They are widely used in scenarios requiring prolonged high-load operation. Existing traditional laptop coolers generally enhance cooling performance by increasing airflow space and improving airflow efficiency, such as using multi-fan bases to blow air upwards or having a perforated bottom to increase airflow. However, this design has a significant drawback: the cool air entering the laptop absorbs heat and is difficult to expel quickly. A large amount of hot air tends to remain in the gaps between the laptop chassis and the cooler, or inside the chassis, forming localized heat buildup. Even with increased airflow, the lack of a directional exhaust path significantly reduces cooling efficiency. Especially when running demanding games or performing high-performance tasks such as video rendering, laptops are still prone to issues like throttling and stuttering due to insufficient cooling.

[0003] Therefore, it is essential to invent an extended cooling system for laptops. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a laptop extended heat sink, comprising a support frame, a tray, anti-slip platforms, limiting protrusions, a converging box, a cooling fan, an airflow channel, an air intake, a connecting hole, and a positioning groove. The tray and the converging box are fixedly installed on the lower sides of the support frame, respectively. At least two anti-slip platforms are fixedly installed on the lower surface of the tray, with a limiting protrusion fixedly installed in the middle above it. A cooling fan is installed on the converging box. Corresponding air intakes are provided on the airflow channel inside the support frame, and connecting holes are provided on both the support frame and the airflow channel. A positioning groove is provided on the inner side of the support frame.

[0005] Preferably, the support frame has an inclined "U"-shaped structure with an "L"-shaped cross-section. The limiting protrusion on the tray on one side of the support frame can restrict the laptop from sliding downwards, and the horizontal protrusion of the laptop's base can be placed into the positioning groove opened in the support frame.

[0006] Preferably, the airflow channel provided on the inner side of the support frame is a "U"-shaped structure made of rubber with both ends sealed, and its cross-section is a hollow rectangle. The low surface of the support frame inside the airflow channel can provide support for the side of the laptop base plate.

[0007] Preferably, the air intakes on the inner surface of the airflow channel are divided into a rear intake and a side intake, which correspond to the rear and side heat dissipation holes of the laptop. The rear intake is located on the inner side of the horizontal portion of the airflow channel, and the side intake is located on the inner side of the vertical portion of the airflow channel.

[0008] Preferably, a connecting hole is provided through the bottom of the inner side of the transverse portion of the airflow channel, and is located between the two rear inlets, with the connecting hole through the airflow channel and the support frame corresponding to each other.

[0009] Preferably, the connecting hole communicates with the converging box, and the converging box has a rectangular structure with its upper opening communicating with the connecting hole provided on the support frame.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This invention achieves precise heat absorption and rapid heat dissipation through a synergistic structure of an airflow channel, air intake, connecting hole, converging box, and cooling fan. The rear and side intake ports inside the airflow channel correspond to the rear and side heat dissipation holes of the laptop, directly drawing in hot air exhausted from the chassis. Guided by the airflow channel, the hot air enters the converging box through the connecting hole and is finally rapidly exhausted by the cooling fan, forming a closed-loop airflow path of "directional intake - concentrated flow - efficient exhaust," effectively preventing hot air from lingering at the bottom of the laptop and around the chassis, and significantly improving heat dissipation efficiency.

[0012] In addition, the airflow channel of this utility model is made of rubber material, whose elasticity can buffer the contact pressure between the laptop and the support frame and prevent the body from being scratched; the "U"-shaped structure with both ends sealed and the hollow rectangular cross section can not only provide stable support for the side of the laptop base, but also adapt to the side contours of laptops of different thicknesses, thus improving device compatibility.

[0013] This utility model's support frame adopts an inclined "U"-shaped structure and an "L"-shaped cross-section. Combined with the anti-slip platform, limiting protrusions, and inner positioning groove on the tray, it can fix the laptop from multiple dimensions: the limiting protrusions prevent the laptop from sliding downwards, the positioning groove adapts to the horizontal protrusions of the laptop base, and the anti-slip platform enhances the friction between the tray and the placement surface. The three work together to prevent the device from shifting, ensure that the air intake and the laptop's heat dissipation holes are always accurately aligned, and reduce the risk of falling.

[0021] As attached Figure 1 To be continued Figure 3 As shown:

[0022] This utility model provides a laptop extended heat sink, comprising a support frame 1, a tray 2, an anti-slip platform 3, a limiting protrusion 4, a converging box 5, a cooling fan 6, an airflow channel 7, an air intake 8, a connecting hole 9, and a positioning groove 10. The tray 2 and the converging box 5 are fixedly installed on the lower sides of the support frame 1, respectively. At least two anti-slip platforms 3 are fixedly installed on the lower surface of the tray 2, and the limiting protrusion 4 is fixedly installed in the middle of its upper part. The cooling fan 6 is installed on the converging box 5. The airflow channel 7 provided on the inner side of the support frame 1 has a corresponding air intake 8. Both the support frame 1 and the airflow channel 7 have connecting holes 9. The positioning groove 10 is provided on the inner side of the support frame 1.

[0023] Furthermore, the support frame 1 is integrally injection molded from ABS engineering plastic, and its overall shape is an ergonomically designed inclined "U" shape with an "L" shaped cross-section, balancing support strength and lightweight characteristics. One side of the support frame 1 is fixedly connected to the tray 2 by bolts. The limiting protrusion 4 on the tray 2 is integrally vulcanized from high-elasticity silicone material. When the laptop is placed on the support frame 1, the limiting protrusion 4 can tightly fit the bottom edge of the laptop, effectively preventing the laptop from sliding downwards. The inner wall of the support frame 1 has a positioning groove 10 with rounded edges, which facilitates precise insertion of the laptop's base lateral protrusion and prevents scratches on the laptop casing.

[0024] Furthermore, an airflow channel 7 is fixed to the inner side of the support frame 1 via a snap-fit ​​structure. The airflow channel 7 is made of high-temperature resistant food-grade silicone, possessing excellent temperature resistance and elasticity. Its overall structure is a "U"-shaped structure with both ends integrally vulcanized and sealed, and its cross-section is a hollow rectangle. The appropriate wall thickness ensures structural stability and elastic cushioning capacity. The lower surface of the support frame 1 inside the airflow channel 7 is slightly lower than the inner surface of the airflow channel 7, and this lower surface is frosted. This allows it to stably support the side of the laptop's bottom plate, preventing the laptop's weight from directly acting on the airflow channel 7, thus protecting the channel structure and ensuring the reliability of the support.

[0025] Furthermore, the air intakes 8 on the inner surface of the airflow channel 7 are designed as rear and side intakes, based on the common locations of laptop cooling vents. The rear intakes are evenly distributed on the inner side of the horizontal portion of the airflow channel 7, corresponding to the common rear cooling vents of laptops; the side intakes are located on the inner side of the vertical portion of the airflow channel 7, with their tilt angle consistent with the tilt direction of the laptop's side cooling vents, enabling precise alignment and enhancing the efficiency of hot air intake. The edges of all intakes 8 are smoothed to reduce airflow turbulence.

[0026] Furthermore, a connecting hole 9 is provided through the bottom of the inner side of the horizontal portion of the airflow channel 7, centrally located between the two rear intake ports, and its hole wall is integrally vulcanized with the airflow channel 7. A corresponding connecting hole 9 is also provided on the support frame 1, and the two are precisely connected by a positioning pin. The connection is sealed with a silicone sealing ring to ensure that hot air can flow without leakage.

[0027] Furthermore, the connecting hole 9 is directly connected to the internal space of the converging box 5. The converging box 5 is injection molded from ABS engineering plastic. Its top opening edge is fixedly connected to the bottom of the support frame 1 by screws. The shape of the opening matches the distribution area of ​​the connecting hole 9 on the support frame 1. An annular step is provided on the inner side of the opening, which is tightly fitted with the sealing gasket at the bottom of the support frame 1, thus achieving a sealed connection between the connecting hole 9 and the converging box 5. This ensures that all hot air can enter the converging box 5 and be discharged by the cooling fan 6.

[0028] The working principle is as follows: First, the laptop is placed on the support frame 1. At this time, the horizontal protrusion of the laptop base will be precisely embedded in the positioning groove 10 on the inner side of the support frame 1. The limiting protrusion 4 on the tray 2 fits tightly against the bottom edge of the laptop. Together with the inclined "U"-shaped structure of the support frame 1, the displacement of the laptop is restricted in both the horizontal and vertical directions. At the same time, the anti-slip platform 3 under the tray 2 increases the friction with the placement surface, ensuring that the laptop is placed stably during use and will not slide or fall.

[0029] When the laptop starts up and generates heat, the hot air exhausted by its built-in cooling system is released from the ventilation holes on the rear and sides. It can also actively draw air out of the laptop through the ventilation holes. Since the rear intake and side intake 8 inside the airflow channel 7 are precisely aligned with the laptop's ventilation holes, and the cooling fan 6 on the converging box 5 starts working, the hot air is quickly drawn into the intake 8 by the suction of the fan and enters the hollow cavity of the airflow channel 7.

[0030] Subsequently, the hot air entering the converging box 5 is rapidly exhausted outward under the continuous action of the cooling fan 6, forming a complete airflow cycle from the laptop's cooling vents → intake port 8 → airflow channel 7 → connecting hole 9 → converging box 5 → cooling fan 6. During this process, the lower surface of the support frame 1 inside the airflow channel 7 provides stable support for the side of the laptop's bottom plate, preventing the laptop's gravity from affecting the airflow channel structure. At the same time, the rubber material of the airflow channel can also buffer vibrations, ensuring the continuous and efficient operation of the cooling system, ultimately achieving directional and rapid heat dissipation for the laptop and effectively reducing the body temperature.

[0031] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
