[0019] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with embodiments of the present invention.

[0020] The preferred embodiments of this utility model will now be described with reference to the accompanying drawings. It should be noted that the terms "upper," "lower," and similar expressions used herein are for illustrative purposes only and are not intended to be limiting.

[0021] In this document, ordinal numbers such as “first” and “second” used in this invention are merely identifiers and do not include any other meaning, such as a specific order.

[0022] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may also include other embodiments.

[0023] Please refer to Figures 1 to 9 In the embodiments of this application, the support device 170 is configured to mount a fan 111 and an air guide shroud 112. The support device 170 includes a fan mounting bracket 120, a frame 130, and a base plate 140. The fan 111 is connected to the fan mounting bracket 120. The frame 130 is connected to the side of the fan mounting bracket 120 where the fan 111 is connected. The base plate 140 is connected to the side of the frame 130 opposite to the fan mounting bracket 120. The air guide shroud 112 is connected to the base plate 140. The fan mounting bracket 120 is connected to only one fan 111. The base plate 140 is connected to only one air guide shroud 112. The fan 111 is connected to the air guide shroud 112.

[0024] As can be seen from the above structure, firstly, the structural arrangement of the fan mounting bracket 120 and the base plate 140 can provide a mounting reference surface for the fan 111 and the air guide shroud 112 to fix the fan 111 and the air guide shroud 112; one end of the frame 130 is connected to the fan mounting bracket 120, and the other end is connected to the base plate 140. Thus, the overall frame formed by the three can not only support the fan 111 and the air guide shroud 112 well to improve the connection stability of the fan 111, the air guide shroud 112 and the support device 170, but also maintain the relative position between the fan 111, the air guide shroud 112 and the support device 170 during the operation of the fan 111. This can effectively improve the situation where the fan 111 is displaced due to vibration during the operation of the fan 111, which is beneficial to improving the reliability of the fan 111 during operation.

[0025] Secondly, the fan mounting bracket 120 is connected to only one fan 111, and the base plate 140 is connected to only one air guide shroud 112. Therefore, the support device 170 can define a dedicated installation space for "one fan 111 + one air guide shroud 112," thereby improving the situation in the prior art where multiple fans share a single support device 170. This structural design effectively improves the vibration transmission generated by different fans during operation in the prior art, thus effectively mitigating the technical problem of noise caused by mutual interference between multiple fans. Therefore, this structural design can effectively reduce noise by reducing vibration transmission during the operation of the fan 111.

[0026] Among them, fan 111 can be a transformer fan or other fans, and there is no restriction here.

[0027] In one embodiment of this application, the fan mounting bracket 120 includes a mounting frame 123, a connecting portion 122, and a mounting plate 124. The connecting portion 122 is connected to the mounting frame 123. The connecting portion 122 extends toward the fan 111. The mounting plate 124 is connected to the connecting portion 122. The fan 111 is disposed on the side of the mounting plate 124 away from the connecting portion 122. In this application, the structure of the mounting plate 124 increases the connection area with the fan 111, thereby improving the connection stability between the fan 111 and the fan mounting bracket 120. The structure of the mounting frame 123 increases the contact area between the bracket device 170 and other connecting structures, thereby improving the connection stability between the bracket device 170 and other connecting structures.

[0028] The projected area of ​​the mounting plate 124 on the base plate 140 is smaller than the area enclosed by the outer contour of the projected area of ​​the mounting frame 123 on the base plate 140. Therefore, by setting the fan mounting bracket 120 as a tapered structure facing the fan 111, the external airflow converges into the fan 111's inlet after being contracted by the inner wall of the mounting frame 123. This effectively reduces airflow separation and eddy current generation, which helps to reduce frictional noise caused by airflow turbulence during the fan 111's intake process, thereby improving the smoothness of airflow entering the fan 111.

[0029] On the other hand, since the stress on a tapered structure is often more concentrated than that on a straight structure, and its rigidity is stronger, by setting the fan mounting bracket 120 as a tapered structure, the resonance of the fan mounting bracket 120 itself can be reduced when the fan 111 is running, thereby further reducing the vibration noise generated by the overall structure.

[0030] Specifically, such as Figure 1 and Figure 5 As shown, the mounting frame 123 is a square flat frame structure, horizontally positioned, with its frame enclosing the central mounting area. The connecting part 122 is a square frustum-shaped frame structure, specifically formed by four inclined planes. The end of the connecting part 122 away from the fan 111 is fixedly connected to the inner edge of the mounting frame 123, and the inner wall of the connecting part 122 extends downward in a gradually tapering incline along the height direction D1 of the support device 170, with the end away from the mounting frame 123 connected to the fan 111. The inclined arrangement of the connecting part 122 not only guides the air intake of the fan 111 but also improves the connection strength between the mounting frame 123, the mounting plate 124, and the fan 111.

[0031] Specifically, the connecting portion 122 includes four flat plates 125. The four flat plates 125 include a first flat plate, a second flat plate, a third flat plate, and a fourth flat plate. The first flat plate, second flat plate, third flat plate, and fourth flat plate are connected circumferentially to form a circumferentially closed annular structure. The first flat plate and the third flat plate have the same inclination angle but opposite inclination directions. The second flat plate and the fourth flat plate have the same inclination angle but opposite inclination directions. The connecting portion 122, formed by the four flat plates 125, has greater rigidity and can more effectively reduce the vibration of the fan 111 during operation.

[0032] Optionally, the fan mounting bracket 120 is a sheet metal part. The connecting part 122 can be a sheet metal part formed by sheet metal processing. The mounting plate 124 is a flat plate structure. The plane of the mounting plate 124 is perpendicular to the height direction D1 of the support device 170. The flat plate structure of the mounting plate 124 is simple.

[0033] In one embodiment of this application, as Figure 1 and Figure 7 As shown, the mounting plate 124 has multiple fan mounting holes 121 around its upper perimeter for fixing the fan 111. Furthermore, the fan mounting holes 121 allow fasteners 110 to pass through them, thus securing the fan 111 to the mounting plate 124. This method not only facilitates installation but also enhances the flexibility of the bracket device 170, allowing users to select different models of fans 111 according to their needs.

[0034] The distance H2 between any fan mounting hole 121 and its corresponding mounting frame edge 126 ranges from 177mm to 178mm. By setting the distance H2 between the fan mounting hole 121 and its corresponding mounting frame edge 126 within the range of 177mm-178mm, on the one hand, it can improve the situation of fan 111 offset during installation, thereby improving the installation positioning accuracy of fan 111; on the other hand, it can also make the central axis of fan 111 basically coincide with the central axis of mounting frame 123 (the axis of the circle extending through the center of multiple fan mounting holes 121), that is, it can improve the coaxiality of fan 111 and mounting frame 123, thereby improving the eccentric vibration caused by low coaxiality during operation of fan 111, and thus reducing the noise generated by eccentric vibration.

[0035] It should be noted that the minimum distance between the center of the fan mounting hole 121 and the corresponding edge 126 of the mounting frame is the smallest among the minimum distances between the center of the fan mounting hole 121 and all the edges 126 of the mounting frame.

[0036] Optionally, the distance H2 between the fan mounting hole 121 and the corresponding mounting frame edge 126 can be 177mm, 177.2mm, 177.3mm, 177.4mm, 177.6mm, 177.7mm, 177.9mm, 178mm, etc., and there is no limitation here.

[0037] It should be noted that, in the embodiments of this application, a total of four fan mounting holes 121 are provided, and the lines connecting the four fan mounting holes 121 form a square structure. The four fan mounting holes 121 are located exactly at the four apex corners of the square structure, and the distance between each fan mounting hole 121 at each apex and the edge 126 of the mounting frame on its corresponding side should be between 177mm and 178mm. Preferably, the square structure is a square, in which case the central axis of the fan 111 coincides with the central axis of the mounting frame 123, the coaxiality between the two is the highest, and the noise generated during the operation of the fan 111 is also the lowest.

[0038] In one embodiment of this application, as Figure 5 and Figure 9 As shown, the support device 170 also includes an elastic pad 160. The elastic pad 160 is disposed on the side of the base plate 140 away from the fan mounting bracket 120, and the end of the air guide shroud 112 connected to the base plate 140 is located between the base plate 140 and the elastic pad 160.

[0039] The elastic pad 160 serves two purposes. First, it absorbs some of the vibrations generated by the fan 111 and the air guide shroud 112 during operation, thereby further reducing the noise generated by the fan 111. Second, the elastic pad 160 also prevents the support device 170 from directly contacting other metal parts. This not only reduces the noise generated by the collision between the support device 170 and other metal parts, but also provides some protection for the support device 170, thus effectively extending its service life.

[0040] Among them, the elastic pad 160 can be a rubber part made of rubber, or a structure made of other elastic materials, which will not be described in detail here.

[0041] The elastic pad 160 can be connected to the base plate 140 by means of adhesive, fasteners, etc., and there are no restrictions on this.

[0042] In one embodiment of this application, the base plate 140 has air guide shroud mounting holes 141 with an axial direction parallel to the height direction D1 of the support device 170, for connecting an air guide shroud 112 via fasteners 110. Multiple air guide shroud mounting holes 141 are spaced apart on the base plate 140. The distance H1 between the air guide shroud mounting holes 141 and their corresponding side edges 142 of the base plate ranges from 45mm to 46mm. This arrangement allows the central axis of the air guide shroud 112 to substantially coincide with the central axis of the base plate 140 (the axis of the circle extending through the multiple air guide shroud mounting holes 141). Since the central axis of the base plate 140 substantially coincides with the central axis of the mounting frame 123, the central axis of the air guide shroud 112 can substantially coincide with the central axis of the mounting frame 123. Consequently, the central axis of the air guide shroud 112 can substantially coincide with the central axis of the fan 111, which helps improve the coaxiality of the air guide shroud 112 and the fan 111, thereby helping to reduce the noise generated by the fan 111 during operation.

[0043] In addition, by setting the distance H1 between the air guide shroud mounting hole 141 and the corresponding edge 142 of the base plate to between 45mm and 46mm, the installation accuracy between the air guide shroud 112 and the base plate 140 can be effectively improved, thereby improving the stability of the air guide shroud 112.

[0044] It should be noted that the minimum distance between the center of the air guide mounting hole 141 and the corresponding edge 142 of the base plate is the smallest among the minimum distances between the center of the air guide mounting hole 141 and all the edges 142 of the base plate.

[0045] The distance H1 between the air guide shroud mounting hole 141 and the corresponding bottom plate edge 142 can be 45mm, 45.1mm, 45.3mm, 45.5mm, 45.7mm, 45.9mm, 46mm, etc., and there is no restriction here.

[0046] It should be noted that in the embodiments of this application, the base plate 140 is a rectangular plate structure, and a circular hole is provided on the base plate 140 for airflow; the elastic pad 160 is an annular structure, which is disposed on the side of the base plate 140 away from the mounting frame 123, and the central axis of the elastic pad 160 coincides with the central axis of the circular hole on the base plate 140, so as to achieve axial sealing of the circular hole.

[0047] In this embodiment, the orthographic projections of the four mounting frame edges 126 onto the base plate 140 correspond one-to-one with the four base plate edges 142. The orthographic projections of the corresponding mounting frame edges 126 onto the base plate 140 coincide with the base plate edges 142.

[0048] There are four air guide shroud mounting holes 141, evenly spaced on the base plate 140, and each air guide shroud mounting hole 141 corresponds to one edge of the base plate 140. Preferably, in this application, the base plate 140 is a square plate structure, and the four air guide shroud mounting holes 141 are located at the midpoints of the four edges of the square.

[0049] In addition, the base plate 140 is fixedly connected to the frame 130, together forming the load-bearing structure of the support device 170. The air guide shroud 112 is connected to the base plate 140 through the air guide shroud mounting hole 141 and is attached to the elastic pad 160.

[0050] In one embodiment of this application, the support device 170 further includes a reinforcing pad 150. The reinforcing pad 150 is disposed between the fan 111 and the mounting plate 124. The reinforcing pad 150 has a transition hole 151. The fan 111 is connected to the mounting plate 124 by fasteners 110 passing through the fan mounting hole 121 and the transition hole 151 in sequence.

[0051] Specifically, such as Figures 3 to 5 ,as well as Figure 8 As shown, multiple transition holes 151 and multiple fan mounting holes 121 are provided in a one-to-one correspondence. Fasteners 110 pass through the fan mounting holes 121 and transition holes 151 in sequence and are then threaded onto the fan 111, so that the fan 111 is connected to the mounting plate 124 by the fasteners 110 passing through the fan mounting holes 121 and transition holes 151 in sequence.

[0052] The reinforcement plate 150 can increase the connection strength between the fan mounting bracket 120 and the fan 111, reduce the vibration of the fan 111 during operation, and thus reduce the noise of the fan 111 during operation.

[0053] Optionally, the reinforcing pad 150 can be a steel plate or a floor-like structure of other materials, without limitation.

[0054] In one embodiment of this application, the thickness of the reinforcing pad 150 along the height direction D1 of the support device 170 ranges from 9mm to 11mm. When the thickness of the reinforcing pad 150 is less than 9mm, the connection strength between the fan mounting bracket 120 and the fan 111 is relatively weak, resulting in relatively large vibrations and thus higher noise when the fan 111 is operating. Conversely, when the thickness of the reinforcing pad 150 is greater than 11mm, the excessive thickness not only wastes internal space of the support device 170 but also increases material costs. Therefore, when the thickness of the reinforcing pad 150 is between 9-11mm, it not only enhances the connection strength between the fan mounting bracket 120 and the fan 111 but also effectively reduces vibration and noise, without wasting internal space of the support device 170, and also effectively reduces material costs.

[0055] Optionally, the thickness of the reinforcing pad 150 can be 9mm, 9.2mm, 9.4mm, 9.6mm, 9.7mm, 10.2mm, 10.5mm, 10.7mm, 10.9mm, 11mm, etc., and there is no limitation here.

[0056] Furthermore, the parallelism of the two opposing surfaces 152 of the reinforcing pad 150 along the height direction D1 of the support device 170 is ≤0.1mm.

[0057] The parallelism of the two opposing sides 152 of the reinforcing pad 150 is set to ≤0.1mm. When the fan 111 is installed on the mounting plate 124, the positional accuracy of the fan 111 on the mounting plate 124 is high, which makes it easy to adjust the coaxiality of the fan 111 and the air guide shroud 112.

[0058] In one embodiment of this application, the thickness of the elastic pad 160 ranges from 8mm to 10mm along the height direction D1 of the support device 170. During operation, the vibration of the fan 111 causes the air guide shroud 112 to vibrate as well. When the thickness of the elastic pad 160 is less than 8mm, its ability to absorb the vibration of the air guide shroud 112 is often insufficient, failing to effectively reduce the noise generated by the fan 111 during operation. Conversely, when the thickness of the elastic pad 160 is greater than 10mm, its thickness makes it prone to mismatches between the support device 170 and external structures, increasing the difficulty of connecting the support device 170 to other external structures. By setting the thickness of the elastic pad 160 to 8mm to 10mm, the elastic pad 160 can not only effectively absorb the vibration of the air guide shroud 112, thereby further reducing the noise generated by the fan 111 during operation, but also improve the connection efficiency between the support device 170 and external structures.

[0059] Optionally, the thickness of the elastic pad 160 can be 8mm, 8.1mm, 8.3mm, 8.4mm, 8.6mm, 8.9mm, 9.2mm, 9.4mm, 9.7mm, 9.9mm, 10mm, etc., and there is no limitation here.

[0060] In one embodiment of this application, the frame 130 includes a first sub-frame 131, a second sub-frame 132, and a connecting beam 133. The first sub-frame 131 is connected to the mounting frame 123. The second sub-frame 132 is connected to the base plate 140. One end of the connecting beam 133 is connected to the first sub-frame 131. The other end of the connecting beam 133 is connected to the second sub-frame 132.

[0061] The aforementioned structure of frame 130 offers several advantages. Firstly, frame 130 possesses high strength. Secondly, the gap between adjacent connecting beams 133 facilitates the installation of the fan 111 and the air guide shroud 112 onto the support assembly 170, and also allows for easy adjustment of the coaxiality of the fan 111 and the air guide shroud 112. Furthermore, the support assembly 170 is both strong and lightweight.

[0062] like Figures 1 to 5 As shown, specifically, frame 130 can be an integral structure formed by welding profiles (such as angle steel). When processing frame 130, after cutting the profiles, welding the profiles completes the processing of frame 130, making the processing of frame 130 convenient.

[0063] The first subframe 131 can be detachably connected to the fan mounting bracket 120 via fasteners 110. The first subframe 131 and the fan mounting bracket 120 can be connected by providing connection holes for the fasteners 110 to pass through, and the structure of the first subframe 131 and the fan mounting bracket 120 is simple.

[0064] like Figure 5 As shown, optionally, the first sub-frame 131 and the second sub-frame 132 are rectangular frames, and the connecting beam 133 connects to the corners of the first sub-frame 131 and the second sub-frame 132, so that the frame 130 is a roughly cuboid structure. The mounting frame 123 is a rectangular structure. The four edges of the mounting frame 123 overlap with the four edges of the first sub-frame 131 respectively. The cuboid frame 130 and the rectangular mounting frame 123 have simple structures.

[0065] This application also provides a fan device 180. The fan device 180 includes a fan 111, an air guide shroud 112, and the aforementioned support device 170. The fan 111 and the air guide shroud 112 are respectively connected to both ends of the support device 170, and the coaxiality between the fan 111 and the air guide shroud 112 is ≤0.1mm. Specifically, since the fan device 180 includes the support device 170 described in the above embodiment, it also has the beneficial effects of the aforementioned support device 170.

[0066] The installation process of the fan equipment 180 in this embodiment is as follows.

[0067] Step 1: Connect the base plate 140 to the frame 130.

[0068] Step 2: Install the air guide cover 112 and elastic pad 160 onto the base plate 140 using fasteners 110.

[0069] Step 3: Install the reinforcing pad 150 and the fan 111 onto the fan mounting bracket 120 using fasteners 110.

[0070] Step 4: Install the fan mounting bracket 120 onto the frame 130 using fasteners 110, and connect the fan 111 to the air guide shroud 112.

[0071] Step 5: Adjust the coaxiality of the fan 111 and the air guide shroud 112 to ensure that the coaxiality of the fan 111 and the air guide shroud 112 meets the requirements.
