Description

Technical Field

[0001] This invention relates to the field of computer technology, and more particularly to a notebook computer. Background Technology

[0002] Like traditional desktop computers, laptop computers consist of a monitor, keyboard / mouse, processor, memory, and hard drive. However, with the same components, laptops are smaller, lighter, and more portable, making them convenient for both work and travel. Therefore, laptops are popular and widely used in people's daily work and life.

[0003] Existing laptops typically include: a bottom shell, a front shell rotatably connected to the bottom shell, a keyboard and touchpad disposed on the side surface of the bottom shell near the front shell, a display screen disposed on the side surface of the front shell near the bottom shell, and components such as a motherboard, a heat dissipation module, and a battery module disposed inside the bottom shell.

[0004] With the development of the electronics industry, the operating speed of electronic components is increasing day by day, and the heat generated by them is also increasing accordingly. In order for electronic components to operate at high speed, the heat generated needs to be dissipated as soon as possible. Otherwise, the electronic components will not work properly and may even be burned out by high temperature. Therefore, laptops need to be equipped with heat dissipation modules to accelerate the heat dissipation of electronic components and ensure that the electronic components work properly.

[0005] Current laptop cooling modules typically include a fan with an exhaust vent, a heatsink fin assembly located at the fan's exhaust vent, and a heat pipe connecting the heatsink fin assembly to the heat-generating electronic components. This cooling module transfers heat generated by the heat-generating electronic components to the heatsink fin assembly via the heat pipe, and then uses the airflow generated by the fan to dissipate the heat from the heatsink fin assembly into the surrounding air, thus satisfying the heat dissipation requirements of the heat-generating electronic components to a certain extent.

[0006] Typically, only a few high-heat-generating electronic components on the motherboard have heat pipes attached to their surfaces, such as the CPU, for forced cooling. Other heat-generating components on the motherboard are left to dissipate heat naturally. However, during operation, all heat-generating components continuously emit heat. Sometimes, natural cooling cannot dissipate the heat generated by other components in time, causing heat to accumulate and exceeding the normal operating temperature of the components. This affects the normal operation of the motherboard, impacting the stability of the laptop and consequently affecting the user experience. This problem has long existed, but the industry has yet to find a solution. Summary of the Invention

[0007] The purpose of this invention is to provide a laptop computer that has a side air outlet on the side wall of the centrifugal fan housing, and an electrically operated cover for opening or closing the side air outlet. When it is necessary to dissipate heat from the heat-generating components facing the side air outlet, the cover is electrically opened to allow the airflow from the centrifugal fan to flow through the side air outlet to these heat-generating components. Thus, while the centrifugal fan is dissipating heat normally through the main air outlet, it can also ensure the heat dissipation of related heat-generating components, ensuring the stable operation of the laptop computer and improving the user experience.

[0008] To achieve the above objectives, the present invention provides a laptop computer, including a base, a motherboard disposed on the base, and a plurality of fans disposed on the motherboard and electrically connected to the motherboard; the fans are centrifugal fans; The fan includes a housing; the housing has a bottom wall and a side wall located at the edge of the bottom wall, the side wall is provided with a main air outlet and several side air outlets, and the side wall is provided with a cover plate that can be rotatably installed on the side wall and can cover the side air outlet, and a motor that can drive the cover plate to rotate and is electrically connected to the main board.

[0009] The fan includes a circuit board disposed within a housing, a motor disposed within a housing and electrically connected to the circuit board, fan blades disposed within a housing and mounted on the motor, and a cover mounted on the housing.

[0010] The circuit board is connected to the motherboard via a ribbon cable to obtain power and signal feedback to control the rotation of the motor, thereby controlling the rotation of the fan blades.

[0011] The motor is connected to the circuit board via a connecting wire, and the circuit board is electrically connected to the main board to obtain power and signal feedback to control the rotation of the motor, thereby controlling the rotation of the cover plate.

[0012] The motor is a miniature motor.

[0013] The motor is fixed to the side wall.

[0014] The cover plate has a rotating shaft on each of its two top sides. The side walls on the top sides of the side air outlets have recesses to accommodate and support the rotating shafts. The side wall has a groove that connects to one of the recesses. The motor is accommodated and fixed in the groove and is fixedly connected to the rotating shaft accommodated in the connected recess. Thus, the rotation of the motor drives the rotation of the shaft connected to it, which in turn drives the cover plate to rotate. The other rotating shaft rotates accordingly, so that the cover plate can be rotatably installed on the side wall of the fan.

[0015] The several side air outlets are considered as one.

[0016] The number of fans is two.

[0017] The side exhaust vent of the fan on the motherboard is positioned to face several heat-generating components on the motherboard. Based on the temperature of the area where the heat-generating components are located and the working status of the heat-generating components, the motor is automatically turned on and off via EC control, thereby realizing the automatic opening and closing of the cover.

[0018] The beneficial effects of this invention are as follows: This invention provides a laptop computer with a side air vent that can be automatically opened and closed on the side wall of a centrifugal fan. The opening and closing degree of the side air vent is automatically adjusted according to the working state of different heat-generating components facing the vent and the temperature of the area where the heat-generating components are located, thereby automatically controlling the provided airflow and dissipating heat in a targeted manner. This ensures that all heat-generating components meet temperature requirements, improves heat dissipation efficiency, guarantees stable operation of the motherboard, and enhances the user experience.

[0023] To further illustrate the technical means and effects of the present invention, the following detailed description is provided in conjunction with the preferred embodiments of the present invention and their accompanying drawings.

[0024] Please see Figures 1 to 3 This invention provides a laptop computer, including a base 2, a motherboard 4 disposed on the base 2, and a plurality of fans 6 disposed on and electrically connected to the motherboard 4. The fans 6 are centrifugal fans. In this embodiment, there are two fans 6.

[0025] The fan 6 includes a housing 60, a circuit board 62 disposed within the housing 60, a motor 64 disposed within the housing 60 and electrically connected to the circuit board 62, fan blades 66 disposed within the housing 60 and mounted on the motor 64, and a cover 68 mounted on the housing 60.

[0026] The housing 60 has a bottom wall 600 and side walls 602 located at the edge of the bottom wall 600. The side walls 602 are provided with a main air outlet 603 and several side air outlets 604. For each side air outlet 604, the side walls 602 are provided with a cover plate 606 rotatably mounted on the side walls 602 and capable of covering the side air outlet 604, and a motor 608 electrically connected to the main board 4 that drives the cover plate 606 to rotate. In this embodiment, the several side air outlets 604 are considered as one. In actual use, the number can be increased accordingly as needed.

[0027] When airflow from a particular side outlet 604 is not required, the cover plate 606 covers the corresponding side outlet 604, thereby blocking the airflow generated by the fan blades 66 from flowing out of that side outlet 604. When airflow from a particular side outlet 604 is required, the motor 608 drives the cover plate 606 to rotate, thereby exposing the side outlet 604, at which point part of the airflow generated by the fan blades 66 flows out from that side outlet 604. The angle of rotation of the cover plate 606 driven by the motor 608 is controlled according to the required airflow rate, thereby controlling the size of the exposed side outlet 604 to meet the required airflow rate.

[0028] The circuit board 62 is connected to the main board 4 via a ribbon cable 620 to obtain power and signal (positive, negative, FG signal, PWM signal) feedback to control the rotation of the motor 64, thereby controlling the rotation of the fan blade 66. Similarly, the motor 608 is connected to the circuit board 62 via a connecting cable 6080, and the circuit board 62 achieves electrical connection with the main board 4 to obtain power and signal (positive, negative, FG signal, PWM signal) feedback to control the rotation of the motor 608, thereby controlling the rotation of the cover plate 606.

[0029] The motor 608 is a micro motor, which is fixed on the side wall 602 and connected to the circuit board 62 of the fan 6 via the connecting wire 6080, thereby obtaining power and signals to control the motor to turn on and off.

[0030] The cover plate 606 has rotating shafts 6060 on its top sides. Recesses 6020 are provided on the side walls 602 on the top sides of the side air outlet 604 to accommodate and support the rotating shafts 6060. Each side wall 602 has a groove 6022 connecting to one of the recesses 6020. The motor 608 is accommodated and fixed within the groove 6022 and is fixedly connected to the rotating shaft 6060 housed in the connected recess 6020. Rotation of the motor 608 drives the rotation of the connected rotating shaft 6060, which in turn drives the cover plate 606 to rotate. The other rotating shaft 6060 rotates accordingly, allowing the cover plate 606 to be rotatably mounted on the side wall 602 of the fan 6. The motor 608 can be fixed in the groove 6022 of the side wall 602 by adhesive application or other methods. The cover plate 606 is relatively fixed in position by the motor 608. Of course, this is only one implementation method, and the cover plate 606 can also be relatively fixed in position using other existing technologies. As long as the motor 608 can control the cover plate 606 to rotate within the side air outlet 604 to open and close the side air outlet 604, any configuration method can be adopted as needed.

[0031] The side exhaust vent 604 of the fan 6 on the motherboard 4 is positioned facing several heat-generating components on the motherboard 4. Preferably, based on the temperature of the area where the heat-generating components are located and the operating status of the heat-generating components, the motherboard 4 can control the motor 608 to automatically open and close via an EC (embedded controller), thereby automatically opening and closing the cover 606. This allows the cover 606 to be opened as needed to provide airflow to the heat-generating components from the side exhaust vent 604, thus preventing the accumulation of heat emitted by the heat-generating components and avoiding affecting their operation. This ensures the stable operation of the motherboard 4 and improves the user experience. When the side exhaust vent is opened to its maximum, the fan speed can be automatically increased if more airflow is required.

[0032] In summary, this invention provides a laptop computer that features an automatically opening and closing side vent on the side wall of a centrifugal fan. The opening and closing degree of the side vent is automatically adjusted according to the operating state of different heat-generating components facing the vent and the temperature of the area where the heat-generating components are located, thereby automatically controlling the provided airflow and dissipating heat in a targeted manner. This ensures that all heat-generating components meet temperature requirements, improves heat dissipation efficiency, guarantees stable motherboard operation, and enhances the user experience.

[0033] As described above, those skilled in the art can make various other corresponding changes and modifications based on the technical solutions and concepts of this invention, and all such changes and modifications should fall within the protection scope of the claims of this invention.
