Description

Technical Field

[0001] This utility model relates to the field of computer technology, and in particular to a fan bracket and heat dissipation module suitable for computer graphics cards. Background Technology

[0002] High-end computer graphics cards on the market are often equipped with excellent heat dissipation designs. A very important aspect of this is the selection and design of the cooling fan. The design of the fan bracket is to enable the cooling fan to better match the heat dissipation module.

[0003] Therefore, in order to achieve better heat dissipation and improve the performance of high-end computer graphics cards, or in order for manufacturers to gain a unique advantage in the market for their high-end computer graphics cards, the demand for fan brackets will increase and the requirements will become more stringent, making the research on fan brackets an inevitable trend.

[0004] In existing technology, traditional fan brackets are usually 120° triangular brackets. Therefore, the cable management position needs to be opened separately on the traditional fan bracket. Usually, this design requires the traditional fan bracket to be attached to the pre-set heatsink. At this time, holes need to be made in the heatsink profile. For high-end computer graphics cards, making holes in the heatsink profile will undoubtedly affect the heat dissipation performance and stability of the entire heat dissipation module.

[0013] In some embodiments, the base has opposing first and second surfaces in its axial direction; the first groove is recessed from the first surface toward the direction of the second surface;

[0014] The crossbeam has an upper surface and a lower surface opposite each other in the axial direction of the base, and the lower surface of the crossbeam is flush with the second surface of the base.

[0015] In some embodiments, both the second groove and the third groove are recessed from the lower surface of the crossbeam toward the upper surface of the crossbeam.

[0023] A thermally conductive layer is coated on the second surface of the base.

[0024] Secondly, this utility model provides a heat dissipation module. The heat dissipation module includes:

[0025] Heat sink with heat dissipation fins, cooling fan, module cover, fasteners, and the aforementioned fan bracket;

[0026] At least a portion of the fastener extends through a mounting hole on the crossbeam of the fan bracket to the module cover, so that the fan bracket can be detachably mounted to the module cover;

Furthermore, the cross-locking design of the first and second cable management sections not only facilitates cable management but also reduces the risk of cracking. In addition, this fan bracket has the advantages of simple structure, convenient processing, and ease of operation. Attached Figure Description

[0049] Figure 1 This is a schematic diagram of the structure of the cooling fan and fan bracket when they are used together, according to an embodiment of the present invention. Figure 2 A schematic diagram of the structure of the fan bracket provided in this embodiment of the utility model (I). Figure 3 A schematic diagram (II) of the structure of the fan bracket provided in this embodiment of the utility model.

Figure 5 Provided for the embodiments of this utility model Figure 3 A magnified view of a section at point B.

[0050] Please see Figures 1-5 The fan bracket 100 includes: a base 1 and four crossbeams 2.

[0051] The aforementioned fan bracket 100 can be used to fix the cooling fan 200, which can be understood as the axial fan of a computer graphics card.

[0052] In this embodiment, the fan bracket 100 can not only fix the cooling fan 200, but also be installed on the module cover of the cooling module, thereby enabling the cooling module using the fan bracket 100 to obtain better heat dissipation effect, and thus improving the market competitiveness of the computer graphics card configured with the cooling module.

[0053] Four crossbeams 2 are symmetrically arranged on the base 1, and each crossbeam 2 extends from the outer edge of the base 1 in a direction away from the base 1.

[0054] Traditional fan brackets are typically 120° triangular brackets, which requires a separate opening on the traditional fan bracket for cable management. Furthermore, the 120° triangular bracket needs to be attached to a pre-installed heatsink, necessitating holes in the heatsink profile. These holes negatively impact the overall heat dissipation performance and stability of the heatsink module. Therefore, compared to traditional fan brackets, this fan bracket 100 offers superior heat dissipation performance and stability while maintaining a simpler structure, easier manufacturing, and greater ease of operation.

[0055] In addition, the base 1 is provided with a first groove 101 and a wire outlet 102; the first groove 101 is coaxially arranged with the base 1, and the wire outlet 102 is connected to the first groove 101.

[0056] In addition, a second groove 201 is provided on one of the four crossbeams 2 corresponding to the outlet notch 102, and a third groove 202 is provided on the other three crossbeams 2.

[0057] It should be noted that the third groove 202 and the second groove 201 are located on the same side, and the two grooves and the first groove 101 are arranged opposite each other in the axial direction of the base 1.

[0058] It is understood that the second groove 201 is provided with a first thread-arranging part 203 and a second thread-arranging part 204, and the second groove 201 has a first sidewall 2011 and a second sidewall 2012 opposite to each other.

[0059] In this embodiment of the application, one end of the first cable management portion 203 is connected to the first sidewall 2011, and the other end extends toward the second sidewall 2012; one end of the second cable management portion 204 is connected to the second sidewall 2012, and the other end extends toward the first sidewall 2011.

[0060] In some embodiments, such as Figures 1-5As shown, the base 1 has a first surface 103 and a second surface 104 opposite each other in its axial direction; the first groove 101 is recessed from the first surface 103 toward the direction of approaching the second surface 104.

[0061] Specifically, the crossbeam 2 has an upper surface 205 and a lower surface 206 opposite to each other in the axial direction of the base 1, and the lower surface 206 of the crossbeam 2 is flush with the second surface 104 of the base 1.

[0062] In some embodiments, in conjunction with Figure - Figure 5 It can be seen that the second groove 201 and the third groove 202 are both recessed from the lower surface 206 of the crossbeam 2 toward the upper surface 205 of the crossbeam 2.

[0063] In some embodiments, according to Figures 1-5 It can be seen that the first thread-arranging part 203 has a first bottom surface 2031 and a first top surface 2032 opposite to each other in the axial direction of the base 1, and the second thread-arranging part 204 has a second bottom surface 2041 and a second top surface 2042 opposite to each other in the axial direction of the base 1.

[0064] To further explain, both the first bottom surface 2031 and the second bottom surface 2041 are flush with the lower surface 206 of the crossbeam 2, and there are preset clamping gaps between the first top surface 2032 and the bottom surface of the second groove 201, and between the second top surface 2042 and the bottom surface of the second groove 201.

[0065] In some embodiments, by Figures 1-5 It can be seen that one of the four crossbeams 2, corresponding to the outlet gap 102, has a first opening 207 and a second opening 208.

[0066] Specifically, the first opening 207 can expose the first thread arrangement part 203, and the second opening 208 can expose the second thread arrangement part 204.

[0067] In some embodiments, refer to Figures 1-5 It can be seen that the end of the crossbeam 2 away from the base 1 is provided with a mounting hole 209.

[0068] In some embodiments, please refer to Figures 1-5 The fan bracket 100 also includes a raised ring 3 and a heat-conducting layer 4.

[0069] The protruding ring 3 protrudes from the first surface 103 of the base 1 and is coaxially arranged with the base 1; a notch is provided on the protruding ring 3 and the position of the notch corresponds to the wire outlet notch 102.

[0070] In addition, the thermally conductive layer 4 is coated on the second surface 104 of the base 1.

[0071] Figure 6This is a schematic diagram of the structure of a fan impeller provided in an embodiment of the present invention.

[0072] Please see Figures 1-6 The heat dissipation module (only the cooling fan 200 and fan bracket 100 of the heat dissipation module are shown in the figure) includes:

[0073] A heat sink with heat dissipation fins (not shown in the figure), a cooling fan 200, a module cover (not shown in the figure), fasteners (not shown in the figure), and the aforementioned fan bracket 100.

[0074] At least a portion of the fastener extends through the mounting hole 209 on the crossbeam 2 of the fan bracket 100 to the module cover, so that the fan bracket 100 can be detachably mounted to the module cover.

[0075] It is understandable that the cooling fan 200 is fixedly connected to the fan bracket 100, and at this time the heat-conducting layer 4 on the base 1 of the fan bracket 100 abuts against the heat dissipation fins of the heat sink.

[0076] In some embodiments, combined with Figures 1-6 It can be seen that the cooling fan 200 includes: a fan body with a wiring harness (not shown in the figure) and a fan impeller 2001.

[0077] It should be noted that at least a portion of the fan body is disposed in the first groove 101 of the base 1. At this time, the wire harness enters the second groove 201 from the wire outlet 102 of the base 1 and is clamped by the first wire management part 203 and the second wire management part 204 of the fan bracket 100.

[0078] Specifically, the fan impeller 2001 is mounted on the fan body.

[0079] To further explain, the cross-locking design of the first wire management section 203 and the second wire management section 204 not only facilitates the reasonable arrangement of the wire harness, but also makes it less likely to crack the wire harness.

[0080] Furthermore, when the wire harness enters the second groove 201 from the wire exit notch 102, the wire harness can be sequentially stopped on the first wire management section 203 and the second wire management section 204 under the guidance of the second groove 102. Therefore, the design of adding the second groove 102 provides the advantage of easy wire exit.

[0081] In summary, when this fan bracket 100 is placed on the heat sink, there is no need to drill holes in the heat sink profile. This allows the fan bracket 100 to facilitate cable management without reducing the heat sink's heat dissipation effect, thereby improving the overall heat dissipation performance of the heat dissipation module.

[0082] In some embodiments, such as Figure 6As shown, the fan impeller 2001 includes: a base 2002 and several blades 2003.

[0083] Among them, a number of blades 2003 are arranged in a predetermined manner along the circumference of the base 2002, and each blade 2003 extends from the outer edge of the base 2002 in a direction away from the base 2002.

[0084] In addition, when the fan impeller 2001 is mounted on the fan body, one end of the base 2002 is close to the protruding ring 3 of the fan bracket 100, so that a sealed receiving space is formed between the base 2002 and the protruding ring 3; the fan body is housed in the receiving space.

[0085] It should be noted that the raised ring 3 can serve as a dustproof structure for the cooling fan 200, preventing external dust from damaging the fan body located in the aforementioned containment space. By incorporating the raised ring 3, the dustproof rating of the cooling fan 200 can reach IP5X, thereby meeting the user's needs and satisfying the structural design requirements of the computer graphics card for the fan bracket.

[0086] Understandably, IP5X indicates a dustproof rating of level 5, meaning it can block most dust, but a small amount of dust may still enter the device, so it cannot completely prevent dust from entering the device. However, the amount of dust entering the device will not affect the normal operation or safety of the device.

[0087] Specifically, when the fan bracket 100 is placed on the heatsink, the lower surfaces 206 of the four crossbeams 2 are close to the heatsink, and the second groove 201 and the third groove 202 can keep the entire fan bracket 100 horizontal after it is installed on the heatsink.

[0088] In summary, the fan bracket and heat dissipation module provided by this utility model embodiment, through the addition of a base and four crossbeams symmetrically arranged on the outer edge of the base, with a cable exit notch on the base, a second groove on one of the four crossbeams corresponding to the cable exit notch, and a third groove on the other three crossbeams, allows for cable management without the need for a separate opening on the fan bracket. This design also facilitates cable exit, ensures the fan bracket can be placed horizontally, and ensures even stress distribution. Furthermore, the cross-locking design of the first and second cable management sections not only facilitates cable management but also reduces the risk of cracking. In addition, this fan bracket has the advantages of simple structure, convenient processing, and ease of operation. Therefore, the fan bracket provided by this utility model embodiment has a certain degree of novelty compared to traditional fan brackets.

[0089] The above description, in conjunction with specific / preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and all of these fall within the protection scope of the present invention.
