Description

Technical Field

[0001] The utility model relates to a heat dissipation module and a fan assembly, in particular to a heat dissipation module and a fan assembly provided with fasteners. Background Art

[0002] With the rapid advancement of technology, the computing power of electronic components has increased significantly, generating significant amounts of heat. To protect electronic components from damage due to excessive heat, fans are installed in electronic products to dissipate excess heat and maintain their operation within a certain temperature range.

[0003] Fans are typically installed in liquid cooling systems or computer cases to dissipate heat from electronic components. For example, in liquid cooling systems, fans are typically secured to the unit using screws. Specifically, the operator must locate and obtain the screws, then use hand tools to tighten the screws to secure the fan to the mounting fixture. However, if the operator cannot find the screws, tightening the screws immediately becomes impossible, making fan assembly inconvenient. Therefore, improving fan assembly ease is a key issue for developers. Utility Model Content

[0044] The heat dissipation module 10 of this embodiment is used to dissipate heat from a heat source (not shown), and includes a fan assembly 20 and a fixing device 30. The fan assembly 20 includes a fan 21, a plurality of fasteners 22, and a plurality of stoppers 23. The fan 21 includes a fan frame 211 and a fan blade 212. The fan blade 212 is rotatably disposed on the fan frame 211. The fan frame 211 is, for example, rectangular. The corners of the fan frame 211 are provided with a plurality of first assembly parts 2111 and a plurality of second assembly parts 2112. These first assembly parts 2111 correspond to these second assembly parts 2112, respectively, and each corresponding first assembly part 2111 and second assembly part 2112 are arranged along the axial direction of the fan blade 212.

[0045] These fasteners 22 are, for example, screws. These fasteners 22 are movably inserted into these first assembly parts 2111 and these second assembly parts 2112, respectively. In detail, each fastener 22 includes a head 221, a first fastening part 222, and a connecting part 223. The head 221 and the first fastening part 222 are respectively connected to opposite ends of the connecting part 223. The diameter of the head 221 is, for example, larger than the diameter of the first fastening part 222 and the diameter of the connecting part 223. The head 221 abuts against the first assembly part 2111. The first fastening part 222 passes through the second assembly part 2112. The connecting part 223 is at least partially located between the first assembly part 2111 and the second assembly part 2112. Each stopper 23 is, for example, mounted on the connecting part 223 in a clamping manner and is located between the first assembly part 2111 and the second assembly part 2112, so as to build the fastener 22 into the sash frame 211. In this way, the stopping member 23 can be stopped between the first assembling portion 2111 and the second assembling portion 2112 to prevent the fastener 22 from falling off from the fan frame 211 .

[0046] In this embodiment, the connecting portion 223 may further include an assembly groove 2231. The assembly groove 2231 is located between the first assembly portion 2111 and the second assembly portion 2112. Each stopper 23 is mounted in the assembly groove 2231, for example, by clamping. This allows the stopper 23 to be positioned in the assembly groove 2231 of the connecting portion 223, preventing the stopper 23 from sliding relative to the connecting portion 223.

[0047] After the first fastening portion 222 passes through the second assembly portion 2112, it can be fastened to the fixing device 30. In detail, the fixing device 30 is, for example, a liquid cooling device, and includes an assembly rack 31, a plurality of heat pipes 32 and a fin group 33. The assembly rack 31 is arranged on the fan frame 211, and includes a frame body 311 and a plurality of second fastening portions 312. These second fastening portions 312 protrude from the frame body 311 and are inserted into the fan frame 211. These first fastening portions 222 are fastened to these second fastening portions 312, respectively. The fin group 33 is arranged on these heat pipes 32. These heat pipes 32 and the fin group 33 are located on the side of the assembly rack 31 away from the fan frame 211. By providing a liquid cooling device, the heat source can be further dissipated.

[0048] In this embodiment, since the fan assembly 20 includes a fastener 22 and a stopper 23, and the fastener 22 is internally mounted on the fan frame 211 of the fan assembly 20 by being stopped by the stopper 23 and does not fall off the fan frame 211, when the operator wishes to install the fan assembly 20 on the fixing device 30, there is no need to find additional external fasteners for fastening. Instead, the fastener 22 internally mounted on the fan frame 211 can be used to immediately secure the fan assembly 20 to the fixing device 30. This improves the ease of assembly between the fan assembly 20 and the fixing device 30.

[0049] Furthermore, since the connecting portion 223 has an assembly groove 2231 and the stopper 23 is mounted in the assembly groove 2231, the stopper 23 can be positioned in the assembly groove 2231 to prevent the stopper 23 from sliding relative to the connecting portion 223. In this way, when the fastener 22 moves relative to the sash frame 211, the stopper 23 can be prevented from falling off the connecting portion 223, thereby further preventing the fastener 22 from falling off the sash frame 211.

[0050] In this embodiment, the number of first assembly parts 2111, the number of second assembly parts 2112, the number of fasteners 22, the number of stoppers 23, the number of heat pipes 32, and the number of second fastening parts 312 are each multiple, but the present invention is not limited thereto. In other embodiments, the number of first assembly parts, the number of second assembly parts, the number of fasteners, the number of stoppers, the number of heat pipes, and the number of second fastening parts may each be only one.

[0051] In this embodiment, the first assembly parts 2111 and the second assembly parts 2112 are provided at the corners of the fan frame 211, but the present invention is not limited thereto. In other embodiments, the first assembly parts and the second assembly parts may also be provided at other locations such as the side of the fan frame.

[0052] In this embodiment, the connecting portion 223 has an assembly groove 2231, and each stopper 23 is installed in the assembly groove 2231, but the present invention is not limited thereto. In other embodiments, the connecting portion may not have an assembly groove, and each stopper may be directly installed in the connecting portion.

[0053] In this embodiment, the fixing device 30 is a liquid cooling device, but the present invention is not limited thereto. In other embodiments, the fixing device may also be other devices such as a housing, as long as the fan assembly can be installed thereon.

[0054] According to the heat dissipation module and fan assembly of the above embodiment, since the fan assembly includes fasteners and a stopper, and the fasteners are retained by the stopper and are built into the fan frame of the fan assembly, preventing them from falling off the frame, when the operator wishes to install the fan assembly on a fixture, there is no need to look for additional external fasteners to secure it. Instead, the fasteners built into the fan frame can be used to instantly secure the fan assembly to the fixture. This improves the ease of assembly of the fan assembly and the fixture.

[0055] Furthermore, since the connecting portion has an assembly groove and the stopper is mounted in the assembly groove, the stopper can be positioned in the assembly groove to prevent the stopper from sliding relative to the connecting portion. This prevents the stopper from falling off the connecting portion when the fastener moves relative to the sash frame, further preventing the fastener from falling off the sash frame.

[0056] Although the present invention is disclosed above with reference to the aforementioned embodiments, they are not intended to limit the present invention. Any person skilled in the art may make slight changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention shall be determined by the scope of protection of the claims attached to this application.
