Description

Technical Field

[0001] This utility model belongs to the technical field of computer heat dissipation devices, specifically a silent integrated heat dissipation device. Background Technology

[0002] During computer operation, the central processing unit (CPU), graphics processing unit (GPU), chipset on the motherboard, and other electronic components generate a lot of heat. If this heat cannot be dissipated effectively and in a timely manner, it may not only lead to performance degradation and system instability, but may even cause hardware failure or permanent damage. Therefore, users usually install cooling fans in the computer case. The airflow generated by the fan rotation effectively exhausts the heat from the heat-generating components outside the case, while reducing the overall temperature inside the case to prevent overheating and ensure system stability and hardware safety.

[0003] There is a cooling device that enhances the heat dissipation performance of a computer by integrating three fans. For example, Chinese patent document "CN109164900A, a cooling device for a communication computer" includes a first fan bracket, a second fan bracket fixedly installed on the right outer surface of the first fan bracket, a third fan bracket fixedly installed on the right outer surface of the second fan bracket, motor mounting brackets fixedly installed on the rear outer surfaces of the first, second, and third fan brackets, a fan blade connector movably installed on the front outer surface of the motor mounting bracket, a fan motor fixedly installed on the inner surface of the fan blade connector, and one end of the fan motor connected to the motor mounting bracket, multiple fan blades provided on the outer surface of the fan blade connector, a motor power cord fixedly installed on the rear outer surface of the motor mounting bracket, a three-in-one adapter provided at one end of the motor power cord away from the motor mounting bracket, and multiple plugs fixedly installed on the bottom outer surface of the three-in-one adapter to achieve compatibility with different power interfaces. The main advantage of this design is that it integrates three fans into one unit, which not only improves the stability of the overall structure but also helps to reduce noise during operation.

[0004] However, this design, with its solid internal structure for the fan bracket, increases the weight of the entire cooling device, potentially causing inconvenience in installation and use. Furthermore, the motor power cable is directly exposed outside the fan bracket, which not only affects the product's aesthetics but also complicates power cable management, especially when dealing with multiple fan connection cables, making organization and maintenance more difficult. Utility Model Content

[0005] The purpose of this invention is to provide a silent integrated heat dissipation device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A silent integrated heat dissipation device includes three integrally formed fan brackets: a first fan bracket, a second fan bracket, and a third fan bracket. Each of the three fan brackets has a mounting hole at its center. A base frame is fixedly mounted on the rear side of each mounting hole. A heat dissipation component is fixedly mounted on the front side of each base frame. A groove is provided at the rear corner of each of the three fan brackets, located on the outer periphery of the mounting hole. A reinforcing rib is provided on each groove, with one end of the reinforcing rib connected to the fan bracket and the other end connected to the side wall of the mounting hole.

[0008] Furthermore, each of the heat dissipation components includes a motor, the output end of which is equipped with a connector, the connector having fan blades, the motor being electrically connected to a power cord, and the other end of the power cord having a plug.

[0009] Furthermore, the base frame includes a fixed base, and the outer periphery of the fixed base is evenly provided with four arc-shaped extensions, the ends of two of which extend to the side wall above the mounting hole, and the ends of the other two extensions extend to the side wall below the mounting hole. The two extensions located below the mounting hole are provided with multiple vertically staggered fixing blocks along their extension path. The corresponding fixing blocks on the extensions form a wiring channel. The side wall of the mounting hole is provided with a wiring groove corresponding to the wiring channel. The reinforcing rib located below the mounting hole is provided with a wire-passing groove. Fan frame one, fan frame two, and fan frame three all include horizontal plates located above and below the mounting hole and vertical plates located on both sides of the mounting hole. The vertical plates are all provided with wire-passing grooves. A wire-concealing groove is provided between the mounting hole and the horizontal plate. The wiring channel, wiring groove, wire-passing groove, wire-passing groove, and wire-concealing groove are all used for power cord routing.

[0010] Furthermore, the base frame is integrally formed with the sidewall of the mounting hole.

[0011] Furthermore, the fan bracket one, fan bracket two, and fan bracket three are placed in parallel.

[0012] Furthermore, fixing screw holes are provided at the corners of the fan bracket one, fan bracket two, and fan bracket three.

[0013] The beneficial effects of this utility model are:

[0014] This invention utilizes a one-piece molding technology to manufacture three fan frames, which not only improves the product's durability but also effectively reduces the vibration and noise generated by the fans during rotation.

[0015] The overall weight of the heat dissipation device is reduced by setting grooves. The grooves are located on the outer periphery of the mounting holes and are equipped with reinforcing ribs. One end of the reinforcing ribs is connected to the fan bracket, and the other end is connected to the side wall of the mounting hole, thus forming a stable support structure. This ensures that the fan bracket maintains extremely high structural strength and stability while being lightweight, effectively preventing deformation or loosening that may be caused by long-term use or high-speed operation, and improving the durability and reliability of the product.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please refer to Figure 1-5 ;

[0025] A silent integrated heat dissipation device includes three one-piece molded fan brackets: fan bracket 1, fan bracket 2, and fan bracket 3. The use of one-piece molding technology to manufacture the three fan brackets not only improves the product's durability but also effectively reduces vibration and noise generated during fan rotation. Each of the fan brackets 1, 2, and 3 has a mounting hole 4 at its center. A base frame 5 is fixedly installed on the rear side of each mounting hole 4, and a heat dissipation component 7 is fixedly installed on the front side of each base frame 5. The heat dissipation component 7 cools the interior of the chassis. Each of the fan brackets 1, 2, and 3 has a groove 6 at its rear corner. The groove 6 reduces the overall weight of the heat dissipation device. The groove 6 is located on the outer periphery of the mounting hole 4 and has reinforcing ribs 61. One end of the reinforcing rib 61 is connected to the fan bracket, and the other end is connected to the side wall of the mounting hole 4, forming a stable support structure. This ensures that the fan brackets maintain extremely high structural strength and stability while being lightweight, effectively preventing deformation or loosening that may occur due to long-term use or high-speed operation, thus improving the product's durability and reliability.

[0026] In this embodiment, the heat dissipation assembly 7 includes a motor 71. The output end of the motor 71 is equipped with a connector 72. The connector 72 is provided with fan blades 73. The motor 71 is electrically connected to a power cord 74. The other end of the power cord 74 is provided with a plug 75. The plug 75 is used to connect to an external power source. When the power source is connected, the motor 71 starts to rotate, driving the connector 72 to rotate continuously. This causes the fan blades 73 on the connector 72 to rotate and generate airflow, blowing external air into the interior of the chassis to cool down the high temperature generated inside the chassis.

[0027] In this embodiment, the base frame 5 includes a fixed base 51. Four arc-shaped extensions 52 are evenly distributed around the outer periphery of the fixed base 51. The ends of two extensions 52 extend to the side wall above the mounting hole 4, and the ends of the other two extensions 52 extend to the side wall below the mounting hole 4. The two extensions 52 located below the mounting hole 4 have multiple vertically staggered fixing blocks 53 along their extension paths. These fixing blocks 53 on the extensions 52 form a wiring channel. The vertically staggered fixing blocks 53 can restrict the power cord 74, preventing it from tilting and being broken by the fan blades 73 when they rotate. The side wall of the mounting hole 4 is provided with... The wiring channel corresponding to the wiring groove 41 is used for the passage of power cables 74. The reinforcing rib 61 below the mounting hole 4 is provided with a wire-passing groove 62. Fan bracket 1, fan bracket 2 and fan bracket 3 all include horizontal plates 12 located above and below the mounting hole 4 and vertical plates 11 located on both sides of the mounting hole 4. Each vertical plate 11 is provided with a wire-passing groove 13. A wire-concealing groove 14 is provided between the mounting hole 4 and the horizontal plate 12. The wiring channel, wiring groove 41, wire-passing groove 62, wire-passing groove 13 and wire-concealing groove 14 are all used for the routing of power cables 74, providing a dedicated routing channel for power cables 74, and routing the three power cables 74 from inside the fan bracket, ensuring the neatness of the heat dissipation device.

[0028] For example, the motor power cable on fan bracket 1 is designated as power cable one, the motor power cable on fan bracket 2 is designated as power cable two, and the motor power cable on fan bracket 3 is designated as power cable three. Power cable one first passes through the wiring channel, wiring groove, wire threading groove, and wire passage groove on fan bracket 1, then continues through the concealed wire groove, wire threading groove, and wire passage groove on fan bracket 2, and then continues through the concealed wire groove and wire threading groove on fan bracket 3, finally exiting from the wire passage groove on fan bracket 3, with the plug protruding outside fan bracket 3; power cable two follows the same pattern. After passing through the wiring channel, wiring groove, wire threading groove, and wire passage groove of fan bracket 2, the wire then passes through the concealed wire groove and wire threading groove of fan bracket 3, and finally exits from the wire passage groove of fan bracket 3, with the plug 75 extending outside fan bracket 3. As for power cord 3, it only needs to pass through the wiring channel, wiring groove, and wire threading groove of fan bracket 3, and finally exit from the wire passage groove. This design can prevent power cord 74 from being exposed, improve the overall aesthetics of the heat dissipation device, and greatly simplify the management of power cord 74, making maintenance more convenient.

[0029] In this embodiment, the base frame 5 and the side wall of the mounting hole 4 are integrally formed, which improves the service life of the heat dissipation device, simplifies the assembly process, and improves production efficiency.

[0030] In this embodiment, fan bracket 1, fan bracket 2, and fan bracket 3 are placed in parallel, so that the fan blades are also parallel, ensuring uniform airflow distribution and improving heat dissipation efficiency.

[0031] In this embodiment, fan bracket 1, fan bracket 2 and fan bracket 3 are all provided with fixing screw holes 15 at their corners. The inner surface of the fixing screw hole 15 is provided with threads for screwing in screws. When the screw is fully screwed into the fixing screw hole 15, a suitable length will extend out of the screw hole. This extended distance is used to install the heat dissipation device on the chassis.
