[0021] The exemplary embodiments of the present application will be described in detail with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

[0022] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the present application should be understood as their common meanings to those skilled in the art to which the present application pertains.

[0023] The embodiments of the present application provide a fan assembly, such as Figure 1 As shown, the fan assembly comprises a cover plate 1, a bottom plate 2, and a side plate 3, the cover plate 1 and the bottom plate 2 and the side plate 3 enclose a cavity, a rotating body 4 is arranged in the cavity, the rotating body 4 can form an air flow by rotating; the side plate 3 is provided with a first air outlet 301, the cover plate 1 is provided with a second air outlet 101, the air flow can be guided out through the first air outlet 301 for heat dissipation of a first heat generating area of an electronic device, and the air flow can be guided out through the second air outlet 101 for heat dissipation of a second heat generating area of the electronic device.

[0024] The fan assembly can be applied to an electronic device, which can be a notebook computer, an electronic keyboard, a server, a television, etc. The cover plate 1, the bottom plate 2, and the side plate 3 jointly enclose a cavity. The cover plate 1 and the bottom plate 2 are respectively located at the top and the bottom of the cavity, and the side plate 3 connects the cover plate 1 and the bottom plate 2 to form the side of the cavity. The rotating body 4 is located in the cavity and can rotate to form an air flow. The rotating body 4 can be a fan blade or a similar rotating device, which generates an air flow by rotating. The side plate 3 can be provided with a first air outlet 301, and the cover plate 1 can be provided with a second air outlet 101, and the two air outlets are respectively used to guide the air flow to different heat generating areas of the electronic device.

[0025] The air flow generated by the rotating body 4 is guided to the first heating area and the second heating area from the first air outlet 301 and the second air outlet 101 respectively, so that the fan assembly can simultaneously cool two different heating areas of the electronic device, ensuring that each area can obtain sufficient air flow for cooling, thereby effectively improving the cooling efficiency.

[0026] In some embodiments, the side of the rotating body 4 and the side plate 3 can form a flow guide channel 5, and the second air outlet 101 is arranged corresponding to the range of the flow guide channel 5.

[0027] The rotating body 4 can be a centrifugal fan, an axial fan, a mixed flow fan, etc., and the fan blades can be arc-shaped, linear, airfoil-shaped, etc. The rotating body 4 can be connected to a motor, which is used to drive the rotating body 4 to rotate. The motor can be located at the center position of the bottom of the cavity. Taking a centrifugal fan as an example, the cover plate 1 and the bottom plate 2 located at the center position of the centrifugal fan can be respectively provided with an air inlet 103. In the rotating state of the centrifugal fan, air is sucked from the air inlet 103 and then thrown out radially along the fan blades under the action of centrifugal force. Therefore, a flow guide channel 5 is naturally formed between the side of the rotating body 4 and the side plate 3. By concentrating and guiding the air flow into the flow guide channel 5, a strong wind area of the fan assembly is formed, thereby improving the flow efficiency of the air flow. The second air outlet 101 can be arranged on the cover plate 1, and its position corresponds to the range of the flow guide channel 5, so that the air flow can smoothly pass through the second air outlet 101 from the flow guide channel 5.

[0028] In some embodiments, the fan assembly can further include a flow guide plate 6, which can be connected to the cover plate 1 at the second air outlet 101. Part of the flow guide plate 6 can extend into the cavity and form an angle with the direction of the air flow. At least part of the air flow can be guided out of the second air outlet 101 under the blockage of the flow guide plate 6.

[0029] The flow guide plate 6 can be located at the second air outlet 101 and connected to the cover plate 1. Part of the flow guide plate 6 can extend into the cavity and form an angle with the direction of the air flow. The flow guide plate 6 can be an inclined flat plate, an arc-shaped plate or other shapes. In the case that the rotating body 4 rotates to generate air flow, the air flow flows in the flow guide channel 5 and flows along the inner wall of the side plate 3 to the first air outlet 301, which is used to cool the first heating area of the electronic device. Since the flow guide plate 6 extends into the cavity and forms an angle with the direction of the air flow, the air flow is partially blocked and changes direction when encountering the flow guide plate 6. The blocked air flow can be guided out of the second air outlet 101 under the guidance of the flow guide plate 6, which is used to cool the second heating area of the electronic device. Through the blockage and guidance of the flow guide plate 6, the air flow can more concentratedly flow to the second heating area, thereby enhancing the cooling effect of the area and avoiding local overheating.

[0030] In some embodiments, the first air outlet and the second air outlet can be rectangular, square, circular, polygonal or other customized shapes, and the appropriate air outlet shape can be selected according to the design requirements.

[0031] In some embodiments, such as Figure 1 As shown, the fan assembly may also include multiple baffles 7, and the portions of the multiple baffles 7 and the guide plate 6 located outside the cavity may be arranged together around the second air outlet 101.

[0032] Multiple baffles 7 and guide vanes 6, located outside the cavity, are arranged around the second air outlet 101. The baffles 7 can be flat plates, curved plates, or other shapes perpendicular to the cover plate 1. The baffles 7 and guide vanes 6 together form a guiding channel around the second air outlet 101, further constraining and concentrating the airflow. Through the cooperation of the baffles 7 and guide vanes 6, the concentration of airflow is significantly enhanced, airflow dispersion and energy loss are reduced, allowing the airflow to flow more efficiently to the second heat-generating area, improving heat dissipation efficiency in that area, and preventing localized overheating.

[0033] In some embodiments, the deflector 6 includes a first surface, which is disposed facing the airflow direction and can form an angle with the airflow direction, which can be an obtuse angle.

[0034] The deflector 6 includes a first surface that is positioned opposite to the direction of airflow, i.e., the first surface faces the direction of airflow. The first surface and the airflow direction can form an obtuse angle (i.e., an angle greater than 90 degrees). For example, the angle can be 100 degrees, 120 degrees, or greater, and the specific angle can be optimized according to the airflow speed and heat dissipation requirements.

[0035] When the rotating body 4 generates airflow, the airflow can flow within the cavity and move towards the second air outlet 101. When the airflow encounters the first surface of the guide plate 6, since the first surface forms an obtuse angle with the airflow direction, the airflow is not abruptly blocked upon encountering the guide plate 6, but is gently guided and its direction is changed. This design reduces the energy loss of the airflow, allowing the airflow to pass through the second air outlet 101 more smoothly and improving the airflow extraction efficiency.

[0036] In some embodiments, such as Figure 2 As shown, the fan assembly may further include: a connecting plate 8, a guide plate 6 which can be slidably connected to the cover plate 1 via the connecting plate 8, the connecting plate 8 being located inside the second air outlet 101 and arranged parallel to the cover plate 1, and the connecting plate 8 being slidable relative to the cover plate 1 to cover at least a portion of the second air outlet 101.

[0037] The connecting plate 8 can be located in the second air outlet 101 and arranged parallel to the cover plate 1. One end of the connecting plate 8 can be connected with the guide plate 6, and the other end can be slidably connected with the cover plate 1. The connecting plate 8 can be connected with the cover plate 1 through a sliding mechanism (such as a sliding rail, a sliding groove, etc.), so that it can slide relative to the cover plate 1. The guide plate 6 is slidably connected with the cover plate 1 through the connecting plate 8. In the case of sliding of the connecting plate 8, the guide plate 6 will also move. The sliding of the connecting plate 8 can cover at least part of the area of the second air outlet 101, so as to adjust the effective opening area of the second air outlet 101. In the case of sliding of the connecting plate 8 to cover part of the area of the second air outlet 101, the amount of air flow discharged will be correspondingly reduced, so as to realize dynamic adjustment of the air flow.

[0038] By sliding the connecting plate 8, the user can manually or automatically adjust the opening size of the second air outlet 101. For example, in the case of needing to enhance heat dissipation, the connecting plate 8 can be slid to completely open the second air outlet 101. In the case of needing to reduce noise or air flow, the connecting plate 8 can be slid to partially cover the second air outlet 101. By adjusting the opening size of the second air outlet 101, unnecessary energy consumption can be reduced, and the energy efficiency of the fan assembly can be improved.

[0039] In some embodiments, one side wall in the second air outlet 101 can extend inwardly to form a sliding groove 102, the connecting plate 8 includes oppositely arranged first and second ends, the first end can extend into the sliding groove 102 and be slidably connected with the cover plate 1, and the second end can be connected with a second surface of the guide plate 6; the second surface is arranged opposite to the first surface.

[0040] The sliding groove 102 can be formed on the inner side wall of the second air outlet 101 and extend inwardly (i.e., a groove or track structure extending inwardly to the inside of the cover plate 1 body). The sliding groove 102 can extend parallel to the cover plate 1 to guide the sliding path of the connecting plate 8. The connecting plate 8 includes first and second ends, wherein the first end can extend into the sliding groove 102 and be slidably connected with the sliding groove 102 to realize linear movement of the connecting plate 8 relative to the cover plate 1. The second end can be fixedly connected with the second surface of the guide plate 6 (the second surface is opposite to the first surface of the guide plate 6, i.e., the other side surface of the guide plate 6).

[0041] In the case of the connecting plate 8 sliding through the sliding groove 102, the second end of the connecting plate 8 can drive the deflector 6 to move synchronously. The movement of the deflector 6 changes the position of the deflector 6 in the cavity. In the case of the connecting plate 8 sliding to the outside of the sliding groove 102, the connecting plate 8 can partially or completely cover the second air outlet 101, reducing the amount of air flow. In the case of the connecting plate 8 sliding to the inside of the sliding groove 102, the second air outlet 101 is gradually opened, increasing the amount of air flow. The extension of the sliding groove 102 provides a stable sliding track for the connecting plate 8, avoiding the deflector 6 from deviating or shaking during movement, and ensuring the accurate adjustment of the position of the deflector 6.

[0042] In some embodiments, as shown in FIG. 1, the fan assembly can further include a resilient member 9. The resilient member 9 can be arranged in the sliding groove 102 and connected to the first end of the connecting plate 8 and the cover plate 1 respectively. The elastic force direction of the resilient member 9 can be parallel to the sliding direction of the connecting plate 8. Figure 2

[0043] The resilient member 9 can be arranged in the sliding groove 102, connected to the first end of the connecting plate 8 at one end and connected to the cover plate 1 at the other end. The elastic force direction of the resilient member 9 is parallel to the sliding direction of the connecting plate 8, i.e. the extension direction of the resilient member 9 is consistent with the movement direction of the connecting plate 8. In the case of the connecting plate 8 being subjected to external force (such as manual adjustment or automatic control), the resilient member 9 will be compressed or stretched. The elastic force of the resilient member 9 will provide a restoring force opposite to the direction of the external force, so that the connecting plate 8 can automatically return to the preset position in the absence of external force.

[0044] The size of the elastic force of the resilient member 9 can be designed according to actual needs to ensure that the connecting plate 8 can slide stably and automatically reset. The material of the resilient member 9 can be selected from metal springs, rubber elastic bodies or other structures with elasticity.

[0045] The resilient member 9 enables the connecting plate 8 to be compressed in the case of increased wind force, thereby increasing the second air outlet 101 and enabling more gas to be blown to the second heating area. In the absence of external force or in the case of reduced wind force, the connecting plate 8 automatically returns to the preset position, thereby achieving automatic adjustment of the opening size of the second air outlet 101. The design of the resilient member 9 makes the sliding of the connecting plate 8 more flexible, enabling the opening size of the second air outlet 101 to be adjusted according to the size of the wind force, thereby flexibly controlling the amount of air flow.

[0046] In some embodiments, the resilient member 9 can have a first state and a second state. In the first state, the deflector 6 can be located in the middle of the second air outlet 101. In the second state, the deflector 6 can abut against the side wall of the sliding groove 102 of the second air outlet 101.

[0047] ​In the first state, the elastic member 9 can be in a natural state, and the guide plate 6 is located in the middle of the second air outlet 101, that is, the second air outlet 101 is partially opened, and the air flow is moderate. In the second state, the elastic member 9 can be compressed to the limit state, and the guide plate 6 abuts against the side wall of the sliding groove 102 of the second air outlet 101, that is, the guide plate 6 completely opens the second air outlet 101. By switching the state of the elastic member 9, the opening size of the second air outlet 101 can be quickly adjusted, so that the air flow is flexibly controlled, and different heat dissipation requirements are adapted.

[0048] In some embodiments, the second air outlet 101 can be rectangular, the width of the guide plate 6 is adapted to the width of the second air outlet 101, and the sliding direction of the connecting plate 8 can be the length direction of the second air outlet 101.

[0049] The second air outlet 101 can be rectangular, and has a clear width and length direction. The width of the guide plate 6 can be adapted to the width of the second air outlet 101, that is, the width of the guide plate 6 is the same as or slightly smaller than the width of the second air outlet 101, so that the guide plate 6 can smoothly slide in the second air outlet 101, reducing friction and resistance in the sliding process. The sliding direction of the connecting plate 8 is the length direction of the second air outlet 101, that is, the connecting plate 8 slides along the length direction of the second air outlet 101, so that the sliding track of the connecting plate 8 is increased, and the air outlet area of the second air outlet 101 can be more flexibly and accurately adjusted.

[0051] The circuit board can be provided with a plurality of heat generating modules (such as CPU, GPU, power module, etc.), and the area formed by the heat generating modules is a first heat generating area. At least part of the area where the keyboard or display screen is located can be a second heat generating area.

The second air outlet 101 can be arranged on the cover plate 1, and another part of the air flow is guided out through the second air outlet 101, which is used to guide the air flow to the area where the keyboard or display screen is located.

[0052] By guiding the air flow from the first air outlet 301 and the second air outlet 101 to different heat generating areas respectively, it is ensured that each area can obtain sufficient air flow for cooling, and the problem of local overheating is avoided. Especially, the heat dissipation of the keyboard or display screen area can reduce the surface temperature, avoid the user from feeling uncomfortable during use, and improve the user experience.
