Description

Technical Field

[0001] This utility model relates to the field of cooling fan technology, and in particular to a PCB integrated cooling fan. Background Technology

[0002] Cooling fans are common devices used in industry and daily life to reduce equipment and ambient temperatures. They work by creating air convection in a localized area through the simple rotation of their blades, thereby dissipating hot air and achieving cooling. Especially in today's rapidly developing technological world, cooling fans, as peripheral devices for electronic products, play an indispensable role in dissipating the heat generated during operation.

[0003] In existing technologies, modular cooling fans typically have a mounting plate in the middle of the frame, with the PCB and drive motor mounted on the plate. Male and female connectors are located on opposite sides of the frame, and connecting cables are used to connect the male and female connectors to the PCB to establish circuit continuity. However, the use of connecting cables makes assembly of the PCB, male and female connectors inconvenient. After assembly, the cables need to be secured with clips or straps, further reducing assembly efficiency. Furthermore, the cables are prone to breakage during assembly. Therefore, improvements are urgently needed to address these issues. Utility Model Content

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] Please see Figures 1 to 5A PCB integrated cooling fan includes a cooling base frame 100, a PCB board 200, a motor module 300, fan blades 400, and a cooling faceplate 500. A mounting base 110 is provided in the middle of the cooling base frame 100, and the mounting base 110 is connected to the cooling base frame 100 via several ribs 120. The PCB board 200 is mounted on the mounting base 110 and has two integrally formed legs 210, which extend along the ribs 120 to both sides of the cooling base frame 100. One leg 210 has an electrical connection to a male connector 600 at its extended end, and the other leg 210 has an electrical connection to a female connector 700 at its extended end. The motor module 300 is electrically connected to the PCB board 200, and the fan blades 400 are connected to the motor module 300. The motor module 300 can drive the fan blades 400 to rotate. The cooling faceplate 500 and the cooling base frame 100 are mutually capped and connected.

[0020] Specifically, in this embodiment, the PCB board 200 has two integrally formed support legs 210. The male connector 600 and the female connector 700 are respectively soldered to the extended ends of the two support legs 210. At the same time, the motor module 300 is soldered to the PCB board 200, thereby forming a whole with the PCB board 200, the motor module 300, the male connector 600 and the female connector 700. This whole is then directly assembled onto the heat dissipation base frame 100, so that the PCB board 200 and the motor module 300 are located on the fixing base 11. At position 0, the support 210 is located at the rib 120, while the male connector 600 and female connector 700 are located on both sides of the heat dissipation base frame 100, which makes the heat dissipation fan easier and simpler to assemble and improves assembly efficiency. At the same time, the integral molding of the PCB board 200 and the support 210 ensures that the PCB board 200 will not easily break after being connected to the male connector 600 and female connector 700 respectively, thus ensuring the connection stability between the PCB board 200, the male connector 600 and the female connector 700.

[0021] In addition, in order to assemble the cooling fan, in this embodiment, a first limiting groove 111 is provided in the fixing base 110, and a fixing shaft 112 is provided in the middle of the fixing base 110. At the same time, a second limiting groove 121 is provided in the rib 120 for the extension of the support leg 210, and the second limiting groove 121 communicates with the first limiting groove 111. After the PCB board 200, motor module 300, male connector 600 and female connector 700 are soldered, the resulting assembly can be directly assembled. The motor module 300 is interference-fitted onto the fixed shaft 112, and the PCB board 200 is placed in the first limiting groove 111, the support leg 210 is placed in the second limiting groove 121, and the male connector 600 and female connector 700 are located on both sides of the heat dissipation base frame 100. This enables the assembly of the PCB board 200, motor module 300, male connector 600 and female connector 700 in a one-piece assembly, making the assembly of the cooling fan convenient and simple.

[0022] For further details, please refer to Figure 2 In this embodiment, to facilitate the assembly of the male connector 600 and the female connector 700, a first slot 130 is provided on one side of the heat dissipation base frame 100, and a second slot 140 is provided on the other side of the heat dissipation base frame 100. When the PCB board 200, motor module 300, male connector 600, and female connector 700 are assembled as a whole, the male connector 600 will snap into the first slot 130, and the female connector 700 will snap into the second slot 140. Within the slot 140, the first slot 130 and the second slot 140 can be used to position the male connector 600 and the female connector 700, thereby facilitating their assembly. After assembly, the first slot 130 and the second slot 140 can effectively prevent the male connector 600 and the female connector 700 from easily breaking from the PCB board 200, thereby improving the connection stability between the PCB board 200, the male connector 600 and the female connector 700.

[0023] Please see Figures 2 to 5 Since the cooling fan in this embodiment is a modular fan, in order to achieve the modular design, the cooling front frame 500 and the cooling bottom frame 100 can form a cooling frame after being closed. At the same time, a modular buckle 800 is provided on one side of the cooling frame, and a modular slot 900 corresponding to the modular buckle 800 is provided on the other side of the cooling frame. When two or more cooling fans are modularly connected, the modular buckle 800 of one cooling fan is fastened into the modular slot 900 of another cooling fan, so that the modular connection between multiple cooling fans can be achieved. The modular buckle 800 and the modular slot 900 are existing technologies, so they will not be described in detail here.

[0024] In addition, to facilitate the assembly of the heat dissipation frames, in this embodiment, a fastening platform 150 is provided on the heat dissipation bottom frame 100, and a fastening groove 510 corresponding to the fastening platform 150 is provided on the heat dissipation front frame 500. By fastening the fastening platform 150 into the fastening groove 510, the heat dissipation front frame 500 and the heat dissipation bottom frame 100 can be connected, making the connection convenient and simple. Of course, screw fixing or other methods can also be used, which are not limited here.

[0025] Finally, to facilitate the installation of the cooling fan on electronic devices, bolt through holes 1000 are provided at the four corners of the heat dissipation frame in this embodiment. Bolts can be inserted through the bolt through holes 1000 to install and fix the cooling fan. At the same time, to ensure the stability after installation, soft rubber pads 2000 are provided at the four corners of the bottom surface of the heat dissipation base frame 100 and the four corners of the top surface of the heat dissipation front frame 500. The soft rubber pads 2000 can dampen the cooling fan during use, thereby effectively reducing the noise generated by the cooling fan during use, ensuring its installation stability, and improving the practicality of the cooling fan.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description; however, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model; furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
