Description

Technical Field

[0001] This utility model relates to the field of chassis heat dissipation technology, and in particular to a fan mounting bracket, a fan assembly, and a chassis. Background Technology

[0002] To ensure adequate heat dissipation, server and other equipment chassis typically have multiple fans installed inside.

[0003] However, due to factors such as the need for cable routing on the side of the fan, there is usually a certain gap between two adjacent fans, resulting in a low fan density, which cannot make the most of the internal space of the chassis and has limited heat dissipation efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a fan mounting bracket, fan assembly, and chassis to address the above problems, thereby increasing fan density and improving heat dissipation efficiency.

[0005] This utility model first provides a fan mounting bracket, comprising: a housing including a first sidewall and a second sidewall arranged opposite to each other, with a first mounting position for mounting a first fan formed between the first sidewall and the second sidewall; and a bracket disposed between the first sidewall and the second sidewall, with a second mounting position for mounting a second fan formed between the bracket and the first sidewall, the second mounting position being adjacent to the first mounting position, a wiring cavity formed between the bracket and the second sidewall, and the bracket having a wiring hole communicating with the wiring cavity and the first mounting position and / or the second mounting position; wherein, the first sidewall and the second sidewall are each provided with a first ventilation opening corresponding to the first mounting position and the second mounting position, and the bracket is provided with a second ventilation opening corresponding to the second mounting position.

[0006] In the aforementioned fan mounting bracket, since the thickness of the second mounting position is smaller than that of the first mounting position, the thickness difference between the second and first mounting positions can be utilized to arrange the cable routing cavity and the second mounting position in layers, making full use of the space inside the housing and avoiding increasing the overall volume of the fan mounting bracket. After the first and second fans are installed in the first and second mounting positions respectively, the cables of the first and second fans are passed through the cable routing holes into the cable routing cavity, allowing the first and second fans to be arranged without gaps. The first and second fans are limited by the edges of adjacent fans, thereby increasing the arrangement density of the first and second fans, improving heat dissipation efficiency, and maximizing the use of the internal space of the housing, simplifying the internal structure of the housing.

[0007] In one embodiment, the wiring hole is located on the edge of the bracket near the first mounting position.

[0008] With this configuration, the wiring hole is positioned close to the first mounting position, making it easier for the cable of the first fan to pass through the wiring hole into the wiring cavity.

[0009] In one embodiment, the bracket includes a frame and a stop, the wiring hole and the second ventilation opening are disposed on the frame, the stop is disposed on one side of the frame facing the second sidewall and located at the edge of the wiring hole and / or the second ventilation opening; and / or, the bracket includes a frame and a flange, the wiring hole and the second ventilation opening are disposed on the frame, the flange is disposed on one side of the frame facing the second sidewall and located at the edge of the bracket near the first mounting position.

[0010] With this design, the baffle can prevent cables passing through the cable routing cavity from accidentally falling into the second mounting position through the cable routing hole and the second ventilation opening and being caught in the second fan; the flange can prevent cables passing through the cable routing cavity from accidentally falling into the first mounting position through the edge of the bracket near the first mounting position and being caught in the first fan.

[0011] In one embodiment, there are multiple first mounting positions and multiple second mounting positions. The first mounting positions are arranged in rows, with the first mounting positions in the same row adjacent to each other. The second mounting positions are arranged in rows, with the second mounting positions in the same row adjacent to each other. Each row of first mounting positions is adjacent to at least one row of second mounting positions.

[0012] This arrangement ensures that each first fan is positioned close to the wiring cavity, making it easy to pass the first fan's cable through the wiring hole into the wiring cavity.

[0013] In one embodiment, the fan mounting bracket further includes a separator disposed on the inner wall surface of the first sidewall and / or the inner wall surface of the second sidewall; at least one separator is provided between each pair of adjacent first mounting positions, and / or at least one separator is provided between each pair of adjacent second mounting positions.

[0014] This design allows the separator to prevent the airflow generated by adjacent first and second fans from interfering with each other, and also improves the stability of the first and second fans within the housing, thus integrating the fan mounting bracket, the first fan, and the second fan into one unit.

[0015] In one embodiment, the housing further includes a third sidewall with its two ends adjacent to the first sidewall and the second sidewall, respectively, and the third sidewall is provided with an interface communicating with the wiring cavity.

[0016] With this configuration, the cables running through the cabling cavity can extend to the interface and connect electrically to external components.

[0017] In one embodiment, a wiring cavity is formed between the first sidewall, the second sidewall, and the third sidewall, and the wiring cavity is connected to the wiring cavity and the interface; the fan mounting bracket also includes a control board disposed in the wiring cavity.

[0018] This configuration allows for easier electrical connection of the first and second fans to external components via the control board, without exposing the control board.

[0019] In one embodiment, the fan mounting bracket further includes a shielding spring disposed on the outer wall surface of the housing; and / or, the housing includes a first shell and a second shell detachably connected, the first shell including a first sidewall and the second shell including a second sidewall.

[0020] With this configuration, the shielding spring is used for conductive bonding, protecting each component from external electromagnetic interference. The shielding spring also provides elastic restraint for the fan mounting bracket. The first and second housings are detachable, making it easy for users to disassemble or repair the components inside the housings.

[0021] This utility model also provides a fan assembly, including a first fan, a second fan and the aforementioned fan mounting bracket, wherein the first fan is mounted at the first mounting position and the second fan is mounted at the second mounting position.

[0022] This utility model also provides a chassis, including the aforementioned fan assembly. Attached Figure Description

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

[0036] To ensure adequate heat dissipation, server and other equipment chassis typically house multiple fans. However, due to factors such as cable management on the sides of the fans, there is usually a gap between adjacent fans, resulting in a low fan density. This fails to maximize the use of internal chassis space and limits heat dissipation efficiency.

[0037] To solve the above problems, such as Figures 1 to 6 As shown, this utility model provides a fan mounting bracket to increase the fan arrangement density and improve heat dissipation efficiency.

[0038] like Figures 2 to 4 As shown, specifically, the fan mounting bracket includes a housing 1 and a support 2, wherein: the housing 1 includes a first sidewall 111 and a second sidewall 121 arranged opposite to each other, and a first mounting position 13 for mounting a first fan 6 is formed between the first sidewall 111 and the second sidewall 121; the support 2 is disposed between the first sidewall 111 and the second sidewall 121, and a second mounting position 14 for mounting a second fan 7 is formed between the support 2 and the first sidewall 111, the second mounting position 14 is adjacent to the first mounting position 13, a wiring cavity 15 is formed between the support 2 and the second sidewall 121, and the support 2 is provided with a wiring hole 211 connecting the wiring cavity 15 with the first mounting position 13 and the second mounting position 14; both the first sidewall 111 and the second sidewall 121 are provided with a first ventilation opening 16 corresponding to the first mounting position 13 and the second mounting position 14, and the support 2 is provided with a second ventilation opening 212 corresponding to the second mounting position 14.

[0039] In the fan mounting bracket provided in this embodiment of the utility model, the first mounting position 13 can be used to install the first fan 6 with a larger thickness, and the second mounting position 14 can be used to install the second fan 7 with a smaller thickness. Since the thickness of the second mounting position 14 is smaller than that of the first mounting position 13, the thickness difference between the second mounting position 14 and the first mounting position 13 can be used to arrange the wiring cavity 15 and the second mounting position 14 in layers, making full use of the space inside the housing 1 and avoiding increasing the overall volume of the fan mounting bracket; after the first fan 6 and the second fan 7 are respectively installed to the first mounting position 13 and the second mounting position 14, the first fan... The cables 9 of the first fan 6 and the second fan 7 are passed through the cable routing hole 211 into the cable routing cavity 15, so that the first fan 6 and the second fan 7 can be arranged without gaps. The first fan 6 and the second fan 7 are limited by the edges of the adjacent fans, thereby increasing the arrangement density of the first fan 6 and the second fan 7, improving the heat dissipation efficiency, and making the most of the internal space of the housing 1, simplifying the internal structure of the housing 1. Furthermore, after the cable routing cavity 15 and the second mounting position 14 are separated by the bracket 2, it can also prevent the cables 9 from being caught in the first fan 6 and the second fan 7, ensuring that the first fan 6 and the second fan 7 can work normally.

[0040] like Figure 3 As shown, in one embodiment, there are multiple first mounting positions 13 and multiple second mounting positions 14. The first mounting positions 13 are arranged in rows, with the first mounting positions 13 in the same row adjacent to each other. The second mounting positions 14 are arranged in rows, with the second mounting positions 14 in the same row adjacent to each other. Each row of first mounting positions 13 is adjacent to at least one row of second mounting positions 14. When there are two rows of first mounting positions 13 and one row of second mounting positions 14, one row of second mounting positions 14 is located between the two rows of first mounting positions 13. This ensures that each first fan 6 is positioned close to the wiring cavity 15, facilitating the routing of the cable 9 of the first fan 6 through the wiring hole 211 into the wiring cavity 15. It can be understood that when there are multiple rows of second mounting positions 14, there can also be multiple brackets 2. Each bracket 2 forms at least one row of second mounting positions 14 between itself and the first sidewall 111, and each bracket 2 forms a wiring cavity 15 between itself and the second sidewall 121. Of course, in other embodiments, the first mounting position 13 may also be arranged around the second mounting position 14, or the first mounting position 13 and the second mounting position 14 may be arranged alternately, as long as each first mounting position 13 is adjacent to at least one second mounting position 14. This utility model embodiment does not impose specific limitations here.

[0041] like Figures 4 to 5As shown in the illustrated embodiment, the wiring hole 211 is located on the edge of the bracket 2 near the first mounting position 13. The wiring hole 211 communicates with both the first mounting position 13 and the second mounting position 14, and its proximity to the first mounting position 13 allows the cable 9 of the first fan 6 to pass more easily through the wiring hole 211 into the wiring cavity 15, preventing the cable 9 of the first fan 6 from being caught in the second fan 7. Since fans typically use side wiring, placing the wiring hole 211 on the edge of the bracket 2 also allows the cable 9 of the second fan 7 to pass more easily through the wiring hole 211 into the wiring cavity 15. Furthermore, there can be multiple wiring holes 211, ensuring that the cable 9 of each of the first fan 6 and second fan 7 can pass through the nearest wiring hole 211 into the wiring cavity 15, further preventing the cable 9 from being caught in the first fan 6 and second fan 7. Of course, in other embodiments, some of the wiring holes 211 may be connected to the first mounting position 13, so that the cable 9 of the first fan 6 can pass through these wiring holes 211 into the wiring cavity 15; the remaining wiring holes 211 may be connected to the second mounting position 14, so that the cable 9 of the second fan 7 can pass through these wiring holes 211 into the wiring cavity 15.

[0042] like Figures 4 to 5 As shown, the bracket 2 includes a frame 21, a stop 22, and a flange 23. A cable routing hole 211 and a second ventilation opening 212 are located on the frame 21. The stop 22 is located on the side of the frame 21 facing the second sidewall 121, and is situated at the edge of the cable routing hole 211 and the second ventilation opening 212. The stop 22 prevents the cable 9 passing through the cable routing cavity 15 from accidentally falling into the second mounting position 14 through the cable routing hole 211 and the second ventilation opening 212 and being caught in the second fan 7, thus protecting the cable 9. The flange 23 is located on the side of the frame 21 facing the second sidewall 121, and is situated at the edge of the bracket 2 near the first mounting position 13. The flange 23 also prevents the cable 9 passing through the cable routing cavity 15 from accidentally falling into the first mounting position 13 through the edge of the bracket 2 near the first mounting position 13 and being caught in the first fan 6, thus also protecting the cable 9. Furthermore, the baffle 22 and the flange 23 can guide the direction of cable 9, prevent cables 9 from getting tangled together, and thus ensure that cables 9 are neatly routed in the cable routing cavity 15.

[0043] like Figures 2 to 4As shown, in one embodiment, the housing 1 further includes a third sidewall 112, with its two ends adjacent to the first sidewall 111 and the second sidewall 121 respectively. The third sidewall 112 has an interface 1121 communicating with the wiring cavity 15. Cables 9 passing through the wiring cavity 15 can extend to the interface 1121 and be electrically connected to external power supplies, controllers, and other components to control the individual or simultaneous operation of each first fan 6 and each second fan 7. By placing the interface 1121 on the third sidewall 112, the space occupied by the interface is not required on the first sidewall 111 and the second sidewall 121, thus avoiding an increase in the overall volume of the housing 1.

[0044] like Figures 3 to 4 As shown in the illustrated embodiment, a wiring cavity 17 is formed between the first sidewall 111, the second sidewall 121, and the third sidewall 112. The wiring cavity 17 communicates with the wiring cavity 15 and the interface 1121. The fan mounting bracket also includes a control board 4 disposed within the wiring cavity 17. Specifically, the control board 4 includes a first terminal 41 and a second terminal 42. The first terminal 41 is located at the interface 1121 and is electrically connected to an external power supply, controller, or other components. There can be multiple second terminals 42. Each cable 9 passing through the wiring cavity 15 extends into the wiring cavity 17 and is electrically connected to each of the second terminals 42. Furthermore, the control board 4 can be detachably fixed to the first sidewall 111 or the second sidewall 121 using fasteners 8 such as screws and bolts. In this way, the first fan 6 and the second fan 7 can be more conveniently electrically connected to an external power supply, controller, or other components via the control board 4. Furthermore, no through holes are opened at the positions of the first sidewall 111 and the second sidewall 121 corresponding to the wiring cavity 17, so that the control board 4 is not exposed, thereby protecting the control board 4 and ensuring that the fan mounting bracket has a neat appearance.

[0045] Of course, in other embodiments, the interface 1121 may also be provided at other locations on the first side wall 111, the second side wall 121 or the housing 1 as needed, so that the cable 9 passing through the wiring cavity 15 can extend to the interface 1121 and be electrically connected to the external power supply, controller and other components, without affecting the normal operation of the first fan 6 and the second fan 7. This utility model embodiment does not impose specific limitations here.

[0046] like Figure 2As shown, housing 1 includes a first housing 11 and a second housing 12 that are detachably connected. The first housing 11 includes a first sidewall 111, and the second housing 12 includes a second sidewall 121. The first housing 11 and the second housing 12 can be detachably fixed together using fasteners 8 such as screws and bolts to ensure the stability and reliability of the connection between the first housing 11 and the second housing 12, while also facilitating the user to disassemble or repair other components inside housing 1, such as the first fan 6, the second fan 7, the control board 4, and cables 9. Specifically, when housing 1 has a square structure, the first housing 11 or the second housing 12 also includes a third sidewall 112, a fourth sidewall 113, and a fifth sidewall 114. The third sidewall 112 and the fourth sidewall 113 are arranged opposite each other, and the two fifth sidewalls 114 are arranged opposite each other.

[0047] like Figures 3 to 4 As shown in the illustrated embodiment, the housing 1 also includes a handle 18 disposed on the fourth side wall 113. Users can hold the handle 18 and push or pull the fan mounting bracket into or out of the chassis, making operation simple and convenient. Furthermore, the handle 18 is arranged opposite to the interface 1121, so that when the fan mounting bracket is pushed into the chassis, the first terminal 41 at the interface 1121 can connect with the terminals of other components such as the power supply and controller inside the chassis. Of course, in other embodiments, the handle 18 can also be disposed at other positions on the housing 1, such as the first side wall 111, the second side wall 121, the third side wall 112, or the fifth side wall 114, as needed; this embodiment of the present invention does not impose specific limitations here.

[0048] like Figure 6 As shown, the fan mounting bracket also includes a partition 3 disposed on at least one of the inner wall surfaces of the first side wall 111 and the second side wall 121; at least one partition 3 is provided between each pair of adjacent first mounting positions 13, and at least one partition 3 is provided between each pair of adjacent second mounting positions 14. The partition 3 can be a insulating material. The partition 3 abuts against the edges of the first fan 6 and the second fan 7, preventing airflow interference between adjacent first fans 6 and second fans 7, further improving heat dissipation. Furthermore, the partition 3 also prevents the first fan 6 and the second fan 7 from vibrating within the housing 1, thereby improving the stability of the first fan 6 and the second fan 7 within the housing 1, achieving integration of the fan mounting bracket, the first fan 6, and the second fan 7.

[0049] like Figures 1 to 2As shown, the fan mounting bracket also includes a shielding spring 5, which is disposed on the outer wall surface of the housing 1. The shielding spring 5 is used for conductive contact, protecting the fan mounting bracket and other components inside the chassis from external electromagnetic interference. Furthermore, the shielding spring 5 is elastic; when the fan mounting bracket is pushed into the chassis, the shielding spring 5 is compressed, thus providing elastic restraint for the fan mounting bracket and ensuring its stability and reliability within the chassis. The shielding spring 5 can be an EMS spring or an EMC spring, etc., to meet electromagnetic susceptibility or electromagnetic compatibility requirements. The shielding spring 5 can be fixed to the outer wall surface of the housing 1 using snap-fit ​​fasteners 8 or other methods.

[0050] like Figures 1 to 2 As shown, this embodiment of the present invention also provides a fan assembly, including a first fan 6, a second fan 7, and the aforementioned fan mounting bracket. The first fan 6 is mounted in a first mounting position 13, and the second fan 7 is mounted in a second mounting position 14. The first fan 6 and the second fan 7 can be detachably fixed to the first sidewall 111 or the second sidewall 121 using fasteners 8 such as screws and bolts. The bracket 2 can be detachably fixed to the second fan 7 or the second sidewall 121 using fasteners 8 such as screws and bolts.

[0051] This embodiment of the invention also provides a chassis including the aforementioned fan assembly. When the fan assembly is pushed into the chassis, the first fan 6 and the second fan 7 can be electrically connected to other components inside the chassis, such as the power supply and controller, to control each of the first fans 6 and each of the second fans 7 to work individually or simultaneously. The chassis can be a server chassis or other equipment requiring fan cooling; this embodiment of the invention does not impose specific limitations on this.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
