Description

Technical Field

[0001] This invention relates to a fan mount, and more particularly to an adjustable fan mount and an electronic device comprising the same. Background Technology

[0002] With the increasing demand for cloud services and artificial intelligence, servers need to process increasingly larger amounts of data. In order to maintain or improve the operating performance and lifespan of electronic components, it is necessary to continuously cool the servers.

[0003] Using fans to generate airflow within a computer chassis to remove heat is the most common cooling method today. Some server chassis provide fan mounts to arrange multiple fans in an array, thereby providing specific airflow distribution within the chassis. Although different areas within the chassis may require different airflow volumes due to variations in component or heat source configurations, traditional fan mounts can only support a single fan size. Therefore, to ensure sufficient airflow to the areas most in need of cooling, fan mounts suitable for larger fan sizes are often installed. However, this approach can lead to some fans providing excessive airflow to areas with lower cooling requirements. In other words, traditional fan mounts force users to install more expensive, larger fans in areas with low airflow demands, making it difficult to reduce overall cooling costs.

[0004] Therefore, there is a need to provide a fan holder and the electronic device containing it to solve the above problems. Summary of the Invention

[0005] In view of this, one object of the present invention is to provide a fan holder and an electronic device therein, thereby solving the aforementioned problems.

[0006] According to an embodiment of the present invention, a fan holder is disclosed, which is adapted to at least a first fan and a second fan. The first fan is larger than the second fan. The fan holder includes a frame and an adjusting member. The frame surrounds a first receiving portion. The size of the first receiving portion corresponds to the size of the first fan. The adjusting member is movably disposed in the frame to switch between a lying position and a vertical position within the first receiving portion. When the adjusting member is in the vertical position, the adjusting member stands upright in the first receiving portion, so as to, together with the frame, surround a portion of the first receiving portion around a second receiving portion, wherein the size of the second receiving portion corresponds to the size of the second fan.

[0007] An electronic device according to an embodiment of the present invention is adapted to at least a first fan and a second fan. The first fan is larger than the second fan. The electronic device includes a chassis and a fan mount. The fan mount is disposed in the chassis. The fan mount includes a frame and an adjustment member. The frame surrounds a first receiving portion. The size of the first receiving portion corresponds to the size of the first fan. The adjustment member is movably disposed in the frame to switch between a lying position and a vertical position within the first receiving portion. When the adjustment member is in the vertical position, the adjustment member stands upright in the first receiving portion to, together with the frame, surround a portion of the first receiving portion around a second receiving portion, wherein the size of the second receiving portion corresponds to the size of the second fan.

[0008] According to the fan bracket and electronic device including it disclosed in the foregoing embodiments of the present invention, since the bracket body is provided with an adjustment member to divide its larger first accommodating portion into a smaller second accommodating portion, the fan bracket can switch between different states without tools by means of the adjustment member, so as to support fans of different sizes or types. Therefore, when this fan bracket is applied to a server, the user can configure a fan array with optimal heat dissipation efficiency and cost considerations for the airflow requirements of different areas using one or more fan brackets.

[0056] Additionally, the term "at least one" may be used below to describe the quantity of the element referred to, but unless otherwise expressly stated, it should not be limited to the case where the quantity is "only one". The term "and / or" may also be used below, which should be understood to include any of the listed items and all combinations of one or more.

[0057] First, please refer to Figure 1 One embodiment of the present invention provides a fan mount 1 and an electronic device 2 comprising the fan mount 1. The electronic device 2 may be, but is not limited to, a computer or server, and may have a chassis 3 for housing one or more fan mounts 1 and other related devices and electronic components (not shown). The fan mount 1 is adapted to house one or more fans of the same (or corresponding) or different sizes (e.g., ...). Figure 1 First Fan 91, Subsequent Figure 9 The second fan 92 or Figure 12 The third fan 93), and one or more fan brackets 1 can be simultaneously housed within a support housing 8, so as to be mounted together with the chassis 3 of the electronic device 2. However, the support housing 8 is optional, and in some embodiments, the fan brackets 1 can also be directly mounted within the chassis 3 by other suitable fixing means.

[0058] Furthermore, it should be noted that, unless otherwise specified, the term "same size (or corresponding size)" as used herein describes an object whose length, width, height (or thickness) is substantially equal to, slightly less than, or slightly greater than that of another object, while "different size" describes an object that differs significantly from another object in only one of its length, width, or height (or thickness). For example, the first fan 91, the second fan 92, and the third fan 93 illustrated in this or subsequent figures may be, but are not limited to, three fans with the same frontal size but different thicknesses, whose dimensions may be, for example, 60×60×38, 60×60×56, and 60×60×76 (in millimeters), respectively. However, these dimensions are merely examples for illustrating the fan frame 1 and do not limit the invention in any way.

[0059] The following will describe fan bracket 1; please refer to [link / reference]. Figures 2-6 ,in Figure 2 This is a 3D schematic diagram of fan bracket 1. Figure 3 This is a side view of fan bracket 1. Figure 4 This is a 3D exploded view of fan bracket 1. Figure 5 This is an exploded side view of fan bracket 1, and Figure 6 This is a partially enlarged side view of the adjusting member 20 of the fan bracket 1 in the first position. It should be noted that the fan bracket 1 in this embodiment is illustrated for example, in a form that supports a 1×2 fan array, but the invention is not limited thereto. Furthermore, to maintain the simplicity of the drawing, Figures 2-6 Only one first fan 91 is shown in the fan bracket 1, and this is used as an example to illustrate the details of the fan bracket 1 in this embodiment.

[0060] In this embodiment, the fan bracket 1 may include a frame 10, at least one adjusting member 20, and a cover 30. Generally, the frame 10 is the part of the fan bracket 1 primarily used to house one or more fans, and it can be made of any suitable metal or plastic material, but the invention is not limited thereto. As shown in the figure, the frame 10 may include a front plate 11, a top plate 12, a bottom plate 13, and a side plate 14. The top plate 12, bottom plate 13, and side plate 14 may all be substantially perpendicular to the front plate 11 and respectively connected to the three adjacent sides of the front plate 11. The top plate 12 and bottom plate 13 are opposite each other, while the side plate 14 connects between the top plate 12 and bottom plate 13. In this configuration, the front plate 11, top plate 12, bottom plate 13, and side plate 14 can collectively form a box-like structure.

[0061] Furthermore, the frame 10 may also include a partition 15, which may be connected to the inner side of the front panel 11 and / or the side panel 14. The partition 15 is substantially perpendicular to the front panel 11 and the side panel 14 and is located between the top panel 12 and the bottom panel 13, thereby dividing the internal area of ​​the frame 10 into two first accommodating portions S for accommodating two fans of the same or different sizes. Correspondingly, the front panel 11 may have at least one first vent 111, which corresponds to and communicates with these first accommodating portions S to facilitate airflow for the fans.

[0062] Taking the first fan 91 shown in the figure as an example, the first fan 91 is adapted to be housed in one of the first receiving portions S. In order to further position the first fan 91, in this embodiment, the inner surface of the front plate portion 11 of the frame 10 may be provided with a plurality of positioning posts 17 protruding inward. These posts can be used to insert into the mounting holes MH at the four corners of the first fan 91 to stabilize the position of the first fan 91 in the first receiving portion S. The mounting holes MH of the first fan 91 may be blind holes or through holes on a general fan housing for screws or bolts to pass through. In addition, the frame 10 in this embodiment may also include a plurality of buffer members 18, which may be, but are not limited to, made of a material with elastic recovery force (such as rubber). The buffer members 18 may be respectively fitted onto the positioning posts 17 so that they are inserted into the holes of the first fan 91 together with the positioning posts 17, thereby buffering and reducing the impact of external forces or vibrations on the first fan 91. However, the positioning posts 17 and the buffer members 18 are optional, and the present invention is not limited by their number and position.

[0063] Additionally, the frame 10 may include at least one first engaging arm 16, connected to the front panel portion 11 and / or the partition portion 15. The first engaging arm 16 is substantially perpendicular to the front panel portion 11 and can be used for assembling and fixing the adjusting member 20. Specifically, the first engaging arm 16 may have at least one assembly slot 161. The adjusting member 20 may include a baffle portion 21 and at least one assembly portion 22. The assembly portion 22 may be integrally formed on one end of the baffle portion 21, and the assembly portion 22 is movably inserted into the assembly slot 161, thereby allowing the adjusting member 20 to be movably connected to the first engaging arm 16. In this embodiment, the adjusting member 20 can slide relative to the frame 10 to a first position (as will be discussed later) via the assembly slot 161 of the first engaging arm 16. Figure 6 As shown), a second position (as follows) Figure 7 (as shown) and a third position (as follows) Figure 10 As shown), and can also be swung relative to the frame 10 at various positions to switch to a lying position (as shown later). Figure 6 , 7 (or as shown in 10) or a vertical state (as shown later) Figure 8 (or as shown in 11).

[0064] It should be further noted that when the adjusting member 20 is switched to the vertical position, it can function as the front panel 11. Therefore, the adjusting member 20 has a first vent 111 similar to the front panel 11. In this embodiment, the baffle portion 21 of the adjusting member 20 may have a second vent 211, so that when the adjusting member 20 is switched to the vertical position, it is aligned with the first vent 111 of the front panel 11, thereby exposing the corresponding fan to maintain smooth airflow. In addition, similar to the positioning post 17 on the front panel 11, in this embodiment, at least one positioning post 23 may also be protruding on the surface of the adjusting member 20, so that it can be inserted into the assembly hole at the corner of the fan when the adjusting member 20 is switched to the vertical position, thereby stabilizing the position of the fan. However, the positioning post 23 may also be optional, and the present invention is not limited to its number and position.

[0065] In addition, to ensure that the adjusting member 20 can be reliably switched to a specific position, in this embodiment, the first engaging arm 16 may also have multiple stop points 162. In one embodiment, the stop points 162 are elastic structures and protrude from the inner edge forming the assembly groove 161. The stop points 162 can be divided into three groups, located at opposite ends and the middle region of the assembly groove 161, respectively, to divide the assembly groove 161 into three engaging holes 1611 and two guide grooves 1612 connecting these engaging holes 1611. As shown in the figure, these three engaging holes 1611 are located at opposite ends and the middle region of the assembly groove 161, respectively, and are at different distances from the first vent 111, and are connected via the guide grooves 1612. Correspondingly, the assembly part 22 of the adjusting member 20 can be a protruding pillar structure. The assembly part 22 can selectively slide along the guide groove 1612 to the engaging hole 1611 in any direction. When the assembly part 22 is subjected to force and passes one of the stops 162 of one set, it can enter one of the engaging holes 1611 and be stopped by the stop 162 of that set to maintain its current position. Furthermore, the assembly part 22 can rotate in the engaging hole 1611 so that the adjusting member 20 can swing and switch between a flat or vertical state regardless of whether it is in the first, second, or third position.

[0066] On the other hand, in order to keep the adjusting member 20 in a vertical state, in this embodiment, the top plate portion 12 of the frame 10 may have at least one slot 121, as shown in the figure. The position of the slot 121 corresponds to two of the engagement holes 1611 on the assembly slot 161 that are relatively far away from the front plate portion 11. Thereby, when the adjusting member 20 moves to one of the two engagement holes 1611 and flips to a vertical state, the end edge of the baffle portion 21 of the adjusting member 20 that is relatively far away from the assembly portion 22 can be engaged into the corresponding slot 121, and the opposite ends of the adjusting member 20 can be fixed to the top plate portion 12 of the frame 10 and the first engagement arm 16, respectively, thereby maintaining the fixed state.

[0067] The cover 30 is detachably assembled to one side of the frame 10 to clamp the fan together with the front plate 11 or the vertically positioned adjustment member 20 of the frame 10. Specifically, the cover 30 may include a rear plate 31 and at least one second engaging arm 32, which is connected to one side of the rear plate 31 and substantially perpendicular to the rear plate 31. The rear plate 31 and the second engaging arm 32 can engage with the top plate 12, the side plate 14, and the first engaging arm 16 of the frame 10. Therefore, in this embodiment, the rear plate 31 may have at least one engaging structure 312, which extends and protrudes from the rear plate 31 and the second engaging arm 32 toward the frame 10, respectively. Correspondingly, the side plate 14 may have at least one engaging structure 141, and the first engaging arm 16 may also have an engaging structure 163. In detail, the engaging structure 312 can be one of a flexible barb structure and a matching locking hole, while the engaging structures 141 and 163 are the other of a flexible barb structure and a matching locking hole. Thus, the cover 30 can be detachably engaged with the engaging structures 141 and 163 of the frame 10 by the engaging structure 312, respectively, and thus fixed to the frame 10. Here, to maintain airflow for the fan, the rear panel 31 can have a third vent 311, corresponding to the first vent 111 of the front panel 11, which exposes the other side of the fan to facilitate airflow.

[0068] First, taking the installation of the first fan 91 as an example, the size of the first fan 91 is actually slightly smaller than the size of the first receiving portion S. In order for the first fan 91 to be installed into the first receiving portion S, the assembly part 22 of the adjusting member 20 can be held in the engagement hole 1611 on the assembly slot 161, which is relatively close to the front plate part 11 (that is, the adjusting member 20 is in the first position), and the adjusting member 20 is held in a flat state, so that the adjusting member 20 is substantially parallel to the extension direction of the assembly slot 161 to maintain the integrity of the first receiving portion S, thereby allowing the first fan 91 to be placed into the first receiving portion S. Next, the cover 30 is assembled and connected to the frame 10, and the first fan 91 can be securely clamped between the frame 10 and the cover 30 to complete the installation of the first fan 91.

[0069] In this embodiment, the fan bracket 1 can also be adjusted via the adjustment member 20 to accommodate fans of other sizes. Please continue reading here. Figures 7-9 , Figure 7 This is a partially enlarged side view of the adjusting component 20 of the fan bracket 1 when it is switched to the second position. Figure 8 This is a schematic diagram illustrating the operation of adjusting component 20 of fan bracket 1 from the second position to a vertical position. Figure 9 This is a schematic diagram of fan bracket 1 accommodating fans of different sizes. For this purpose, the cover 30 can be removed first, and then, as... Figure 7This allows the adjusting member 20 to slide in the direction of the arrow, causing its assembly part 22 to slide via the guide groove 1612 to the engagement hole 1611 in the middle region of the assembly groove 161 (i.e., causing the adjusting member 20 to slide to the second position). Next, as... Figures 8-9 The adjusting member 20 can be rotated from a lying position to a vertical position in the direction of the arrow, so that the edge of its baffle portion 21, which is away from the assembly portion 22, can be inserted into one of the slots 121 of the top plate portion 12, thereby maintaining the adjusting member 20 in its current state. At this time, the adjusting member 20 is substantially perpendicular to the extension direction of the assembly slot 161 and stands upright in the first receiving portion S, so that together with the top plate portion 12, the side plate portion 14, and the partition portion 15 of the frame 10, it surrounds a portion of the first receiving portion S to form a second receiving portion S'. The size of this second receiving portion S' is smaller than the size of the first fan 91, but substantially equal to or slightly larger than the size of the second fan 92. The user can put the second fan 92 into the second receiving portion S'. When it is positioned, the second fan 92 can abut against the adjusting member 20, and the positioning post 23 of the adjusting member 20 can be inserted into the assembly holes MH at the four corners of the second fan 92 to further stabilize the position of the second fan 92. The position and distribution of the assembly holes MH of the second fan 92 are substantially the same as those of the assembly holes MH of the first fan 91. Next, the cover 30 can be assembled onto the frame 10 to clamp the second fan 92 together with the frame 10, thus completing the installation of the second fan 92.

[0070] Furthermore, by adjusting the adjusting member 20, it can also be adapted to accommodate a fan that is thinner or shorter than the second fan 92. For example, please refer to [further details]. Figures 10-12 , Figure 10 This is a partially enlarged side view of the adjusting member 20 of the fan bracket 1 when it is switched to the third position according to an embodiment of the present invention. Figure 11 This is a schematic diagram illustrating the operation of adjusting component 20 of fan bracket 1 from the third position to a vertical position. Figure 12 This is a schematic diagram of fan bracket 1 accommodating fans of different sizes. For this purpose, the cover 30 can be removed first, and then, as... Figure 10 This allows the adjusting member 20 to slide in the direction of the arrow, causing its assembly part 22 to slide via the guide groove 1612 to the engagement hole 1611 furthest from the front plate part 11 in the assembly groove 161 (i.e., causing the adjusting member 20 to slide to the third position). Next, as... Figures 11-12The adjusting member 20 can be rotated from a lying position to a vertical position in the direction of the arrow, so that the edge of its baffle portion 21, which is away from the assembly portion 22, can be engaged into another slot 121 of the top plate portion 12, thereby maintaining the adjusting member 20 in its current state. At this time, the second receiving portion S' is further reduced to a third receiving portion S'", and the size of this third receiving portion S' is smaller than the size of the second fan 92, but substantially equal to or slightly larger than the size of the third fan 93. When the user places the third fan 93 into the third receiving portion S' and positions it, the third fan 93 can abut against the adjusting member 20, and the positioning post 23 of the adjusting member 20 can be inserted into the assembly holes MH at the four corners of the third fan 93 to further stabilize the position of the third fan 93. The position and distribution of the assembly holes MH of the third fan 93 are substantially the same as those of the assembly holes MH of the first fan 91. Next, the cover 30 can be assembled to the frame 10 to clamp the third fan 93 together with the frame 10 to complete the installation of the third fan 93.

[0071] Therefore, it can be understood that the fan bracket 1 of this embodiment can be switched between different states without tools via the adjustment member 20 to support fans of different sizes or types. It is also understood that the other adjustment member 20 can be adjusted according to the foregoing description to selectively accommodate the required fan. Furthermore, in applications where this fan bracket 1 is used in the support housing 8 to form a fan array, the user can utilize the adjustability of the fan bracket 1 to configure a fan array with optimal heat dissipation efficiency and cost considerations based on the airflow requirements of different areas.

[0072] However, it should be noted that the adjustment member 20 in the aforementioned embodiment is merely illustrative and not intended to limit the present invention. Any mechanism capable of switching the position of the aforementioned adjustment member relative to the frame should be applicable to the present invention. For example, please refer to... Figures 13-15 ,in Figure 13 This is an exploded perspective view of the adjustment member 20' according to another embodiment of the present invention. Figure 14 This is a partially enlarged side sectional view of the adjusting part 20', and Figure 15 This is a partially enlarged schematic diagram of the frame 10' used in conjunction with the adjustment component 20'. For the purpose of brief explanation, the following description only focuses on the differences between this embodiment and the previous embodiments. Similar or identical parts can be understood by referring to the corresponding content above and will not be described again.

[0073] In this embodiment, the assembly part 22' of the adjusting member 20' may include a pin 221, an elastic member 222, and a sleeve 223. The pin 221 may include an abutting protrusion 2211, an annular protrusion 2212, and a through post 2213. The annular protrusion 2212 is connected between the through post 2213 and the abutting protrusion 2211. The sleeve 223 may be fixed to the baffle part 21 of the adjusting member 20' by any suitable means. The through post 2213 is movably inserted into the sleeve 223. The elastic member 222 is, for example, a compression spring, which may be sleeved on the through post 2213 and sandwiched between the annular protrusion 2212 and the inner wall surface of the sleeve 223 to drive the abutting protrusion 2211 to protrude from the baffle part 21 of the adjusting member 20'. The portion of the abutment protrusion 2211 that protrudes from the baffle portion 21 under the action of the elastic member 222 has a gradually tapering shape and has two opposing abutment slopes 22111 at an angle to each other. A midline 22112 is connected between the abutment slopes 22111, and the midline 22112 is a relatively flat or slightly curved narrow surface between the abutment slopes 22111.

[0074] Accordingly, the guide groove 1612' between the engagement hole 1611' of the assembly groove 161' of the first engaging arm 16' of the frame 10' does not penetrate the first engaging arm 16', but is only a slight indentation from the inner surface of the first engaging arm 16'. See here. Figure 16 To assemble the adjusting member 20' onto the frame 10', for example, the assembly part 22' of the adjusting member 20' can be selectively engaged with one of the engagement holes 1611'. Specifically, the abutting slope 22111 of the ejector pin 221 of the adjusting member 20' can abut against the first engagement arm 16'. The force between the two can force the ejector pin 221 to retract inward toward the sleeve 223, so that the ejector pin 221 can pass over the solid part of the first engagement arm 16' and move into one of the engagement holes 1611'.

[0075] Next, please refer to Figures 17-18When the adjusting member 20' is in a flat position, the abutting slope 22111 of its ejector pin 221 is substantially facing the guide groove 1612'. In other words, the abutting slope 22111 is arranged along the extension direction of the guide groove 1612', and the center line 22112 between the abutting slopes 22111 is perpendicular to the extension direction of the guide groove 1612'. Therefore, applying a force to the ejector pin 221 in the direction of the guide groove 1612' will cause the periphery of the engaging hole 1611' to abut the abutting slope 22111, thereby forcing the ejector pin 221 to retract inward, so that the ejector pin 221 can enter the guide groove 1612' on the inner wall of the first engaging arm 16'. However, when the adjusting member 20' is in a vertical state, the abutting slope 22111 of its ejector pin 221 does not face the guide groove 1612'. In other words, the abutting slope 22111 is arranged along the extension direction perpendicular to the guide groove 1612', and the center line 22112 between the abutting slopes 22111 turns to a position parallel to the extension direction of the guide groove 1612'. Therefore, applying a force to the ejector pin 221 along the direction of the guide groove 1612' cannot force the ejector pin 221 to retract. That is to say, when the adjusting member 20' is in a vertical state, the design of the assembly part 22' of the adjusting member 20' can prevent the adjusting member 20' from undergoing unexpected displacement due to external force. The phrase "the abutting inclined surface 22111 is substantially facing the guide groove 1612'" means that the normal of the imaginary symmetry plane of the abutting inclined surface 22111 is substantially parallel to the extension direction of the guide groove 1612', while "the abutting inclined surface 22111 is not facing the guide groove 1612'" means that the normal of the imaginary symmetry plane of the abutting inclined surface 22111 is substantially perpendicular to the extension direction of the guide groove 1612'.

[0076] Furthermore, the fan bracket of this invention can also be adjusted according to other needs. For example, please refer to... Figure 19 In another embodiment of the present invention, a fan holder 1' is provided, which differs from the fan holder of the aforementioned embodiment in that the position of the positioning post 23 of one of the adjusting members 20” of the fan holder 1' is adjusted to the side of the adjusting member 20” facing the first receiving portion S. Therefore, when the adjusting member 20” is switched to a vertical state, it is suitable to accommodate a fan of a corresponding size (such as the third fan 93 shown in the figure) in the space between the adjusting member 20” and the front plate portion 11 of the frame 10' (such as the third receiving portion S” shown in the figure). In other words, in this embodiment, the fan can be clamped and positioned by the frame 10' and the adjusting member 20”, thereby eliminating the need for the cover of the aforementioned embodiment.

[0077] Finally, it should be noted that the fan bracket of the present invention can be adjusted to support different fan array configurations as needed. For example, in other embodiments, the fan bracket may be reduced in size to support only a single fan; or in other embodiments, the fan bracket may be increased in overall size to support a larger number of N×M fan arrays, where N and M can be positive integers greater than 2. Furthermore, the present invention is not limited to the size or type of fan that the fan bracket can support, but the number of engaging holes and guide slots in the assembly slot can be adjusted according to the required number of fan sizes. For example, in some other embodiments of the fan bracket, the assembly slot may have only two engaging holes, allowing the adjusting member to switch between a flat or vertical position only between a first and a second position. In this case, the fan bracket may only be suitable for supporting two different sizes of fans.

[0078] According to the fan bracket disclosed in the foregoing embodiments of the present invention, different states can be switched without tools by means of an adjustment component to support fans of different sizes or types. Therefore, in server applications where this fan bracket is installed, users can configure fan arrays with optimal cooling efficiency and cost considerations for the airflow requirements of different areas using one or more fan brackets.

[0079] While the present invention has been disclosed above with reference to the foregoing embodiments, it is not intended to limit the invention. Modifications and alterations made by those skilled in the art without departing from the spirit and scope of the invention are all within the scope of patent protection of the present invention. For the scope of protection defined by the present invention, please refer to the appended claims.
