Technical Field

[0001] The exemplary embodiments disclosed herein generally relate to the field of compressor technology, and particularly to a fan assembly and a compressor. Background Technology

[0002] Fans are used to guide airflow and are typically deployed in equipment such as compressors. However, existing fan installation methods are not very convenient and are quite difficult, which hinders the improvement of fan assembly and maintenance efficiency.

Detailed Implementation

[0017] Preferred embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0018] The term "comprising" and its variations as used herein signify open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "at least partially based on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "first", "second", etc., may refer to different or the same objects.

[0019] As mentioned earlier, fans are used to guide airflow and are typically required in equipment such as compressors. Fan installation and removal are crucial steps in the production and maintenance of equipment like compressors. Some existing fan installation processes involve inverting the air guide cover on the ground and mounting the fan onto it. Then, the fan and air guide cover are flipped and hoisted onto the equipment for connection. This installation method not only occupies floor space, but the flipping process for the fan and air guide cover is also quite difficult. Especially when the fan and air guide cover are heavy and large, the flipping process is not only difficult to operate but also poses safety risks, resulting in poor convenience for equipment inspection and maintenance.

[0020] Some devices have brackets below the air guide shroud for temporary fan mounting. During fan installation, the air guide shroud is first installed on the device (e.g., the compressor housing). The fan is then lifted under the air guide shroud and temporarily secured using the brackets. Finally, the fan and air guide shroud are connected using fasteners such as bolts. However, the space under the air guide shroud is usually limited. When the fan itself is relatively large, the available operating space is very small, making installation difficult, time-consuming, and labor-intensive, hindering assembly and maintenance efficiency. If the fan is also relatively heavy, lifting equipment is needed to support it, further complicating the operating space, making the fan assembly and disassembly process less user-friendly, and compromising safety.

[0021] To address, or at least partially address, the aforementioned problems or other potential problems existing in conventional technologies, embodiments of this disclosure provide a fan assembly. In this improved solution, the fan assembly includes a fan and an air guide shroud. The fan includes a fan body and a plurality of first connecting portions spaced circumferentially along the fan body, the plurality of first connecting portions connecting to and protruding from the outer periphery of the fan body. The air guide shroud is provided with an air inlet adapted for the fan body to pass vertically through, and a plurality of connecting members corresponding to the plurality of first connecting portions and arranged circumferentially spaced along the air inlet. Each connecting member includes a first notch, a second connecting portion, and a support bracket. The first notch is formed at the periphery of the air inlet and adapted for the corresponding first connecting portion to pass vertically through. The first notch and the second connecting portion are arranged circumferentially along the air inlet, and the second connecting portion is detachably connected to the corresponding first connecting portion to connect the fan body to the air inlet. The support bracket is located below the first notch and the second connecting portion and is connected to the air guide shroud, the support bracket being adapted to support the first connecting portion located below the first notch or the second connecting portion.

[0022] During the assembly of the fan and air guide cover, the air guide cover can be arranged laterally, for example, it can be attached to the compressor housing. The fan is hoisted above the air guide cover, aligning the fan body with the air inlet, and aligning the multiple first connecting parts with the multiple first notches. The fan height is gradually lowered, with the fan body at least partially passing through the air inlet, and the multiple first connecting parts passing through the multiple first notches and supported by multiple support brackets, thus temporarily supporting the fan at the air inlet. Then, the fan is rotated so that the multiple first connecting parts are aligned with the multiple second connecting parts. Connecting the multiple first connecting parts to the multiple second connecting parts completes the assembly of the fan and air guide cover. This method reduces the difficulty of fan assembly, especially for fans that are relatively heavy and large, and also improves the safety of the fan assembly process, facilitating easier assembly and maintenance. Furthermore, since the air guide cover does not need to be placed on the ground and the fan is installed from top to bottom, it also saves floor space.

[0023] Figure 1 and Figure 2 Perspective views of fan assemblies according to various embodiments of the present disclosure are shown from different viewpoints. To facilitate the illustration of the first connecting portion of the fan and the connecting parts disposed on the air guide shroud, in... Figure 1 and Figure 2 The fan casing and impeller are partially obscured. See also Figure 1 and Figure 2 As shown, the fan assembly of an embodiment of this disclosure includes a fan 100 and an air guide shroud 200. These components will be described below with reference to the accompanying drawings and examples.

[0024] The fan 100 includes a fan body 110 and a plurality of first connecting portions 120 arranged circumferentially along the fan body 110. The plurality of first connecting portions 120 are connected to and protrude from the outer periphery of the fan body 110.

[0025] In some examples, the fan body 110 may include a housing, an impeller disposed within the housing, and a fan drive motor driven by the impeller. As an example, the housing may employ a grille structure. Thus, driven by the impeller, airflow flows into the housing from one side of the housing via the grille structure, and then flows out of the housing from the other side of the housing via the grille structure (e.g., out into the air guide shroud 200).

[0026] Multiple first connecting portions 120 are used to connect to the air guide shroud 200. In practical applications, the first connecting portions 120 can adopt any suitable structure. In some examples, the first connecting portion 120 may include a lug protruding from the outer periphery of the fan body 110, and the lug may have a through hole or a screw hole. The lug can be connected to the air guide shroud 200 by fasteners such as screws, bolts, or rivets. As an example, the outer periphery of the fan body 110 may be provided with a U-shaped lug, the middle of which defines a through hole. Of course, the first connecting portion 120 may also include other suitable structures such as a snap-fit ​​structure.

[0027] The air guide shroud 200 is provided with an air inlet 204 suitable for the fan body 110 to pass through vertically, and a plurality of connecting members corresponding to a plurality of first connecting portions 120 and arranged circumferentially at intervals along the air inlet 204. In some embodiments, combined with Figure 1 and Figure 2 As shown, the air guide shroud 200 may include an end wall 201 and a peripheral wall 202 surrounding the end wall 201, with the bottom end of the peripheral wall 202 connected to the outer periphery of the end wall 201. The end wall 201 and the peripheral wall 202 together define the inner cavity 203 of the air guide shroud 202. The end wall 201 is provided with an air inlet 204 communicating with the inner cavity 203 and a plurality of connecting components arranged circumferentially along the air inlet 204.

[0028] As an example, continue to combine Figure 1 and Figure 2 As shown, the end wall 201 can be rectangular or square, and a circular air inlet 204 can be provided in the middle of the end wall 201. Multiple connecting components can be deployed at the periphery of the air inlet 204, and these components can be spaced apart circumferentially along the air inlet 204. The peripheral wall 202 can include four sidewalls, which are connected to form a cuboid-shaped peripheral wall 202. The bottom end of the peripheral wall 202 can be connected to the outer periphery of the end wall 201 to jointly form a cuboid-shaped air guide shroud 200 with a top opening 225. It should be understood that the air guide shroud 200 described above is merely exemplary. In practical applications, the air guide shroud 200 can also adopt any other suitable structure, such as an arc-shaped or hemispherical shape, etc. The embodiments disclosed herein do not limit this.

[0029] In some embodiments, continue to combine Figure 1 and Figure 2 As shown, at least one flange 240 can be provided at the top of the peripheral wall 202, and the flange 240 is provided with a third through hole 241 and / or a positioning pin 242. The air guide shroud 200 can be connected to the housing 300 of equipment such as a compressor through the flange 240. As an example, the tops of a pair of opposite sidewalls of the four sidewalls can be provided with flanges 240 that bend outwards, and a plurality of third through holes 241 and a plurality of positioning pins 242 can be provided at intervals on these two flanges 240. The tops of another pair of opposite sidewalls of the four sidewalls can be provided with flanges 240 that bend inwards.

[0030] In some embodiments, the air guide shroud 200 may be provided with multiple connecting members at equal or approximately equal intervals along the circumference of the air inlet 204. Each of the multiple connecting members may correspond one-to-one with a multiple of the first connecting portions 120. For example, four connecting members may be provided at the four corners near the end wall 201 and near the periphery of the air inlet 204.

[0031] Figure 3 A perspective view of an air guide shroud 200 according to some embodiments of the present disclosure is shown. (In conjunction with...) Figures 1 to 3As shown, the connecting components include a first notch 205, a second connecting portion 210, and a support bracket 220. The first notch 205 is formed at the periphery of the air inlet 204 and is adapted to allow the corresponding first connecting portion 120 to pass vertically through it. The first notch 205 and the second connecting portion 210 can be arranged circumferentially along the air inlet 204; for example, the second connecting portion 210 can be arranged clockwise or counterclockwise from the first notch 205. The second connecting portion 210 is detachably connected to the corresponding first connecting portion 120 to connect the fan body 110 to the air inlet 204. The support bracket 220 is located below the first notch 205 and the second connecting portion 210 and is connected to the air guide shroud 200. The support bracket 220 is adapted to support the first connecting portion 120 located below the first notch 205 or the second connecting portion 210.

[0032] In some embodiments, the position of the first notch 205 may correspond to the position of the first connecting portion 120, and the vertical projection of the first notch 205 may cover the vertical projection of the first connecting portion 120 to allow the corresponding first connecting portion 120 to pass vertically through the first notch 205. As an example, the air inlet 204 may be circular, the first notch 205 may be U-shaped or semi-circular, and the first connecting portion 120 may also be U-shaped or semi-circular. The size of the first notch 205 may be larger than the size of the first connecting portion 120 so that the vertical projection of the first notch 205 covers the first connecting portion 120.

[0033] In some embodiments, the second connection portion 210 may be located on one side of the first notch 205 in the clockwise direction, or on one side of the first notch 205 in the counterclockwise direction. Figure 4 A perspective view of a portion of the structure of an air guide shroud 200 according to some embodiments of the present disclosure is shown. Figure 3 and Figure 4 As shown, in some embodiments, the second connecting portion 210 may include a first through hole 212 penetrating the air guide shroud 200 and a fastener matching the first through hole 212. The fastener and the first through hole 212 cooperate to connect with the first connecting portion 120. In some examples, the fastener may include a bolt (not shown) passing through the first through hole 212 and the first connecting portion 120, and a nut connected to the bolt. As an example, the nut 211 may be disposed above the end wall 201, and the nut 211 may be fixedly connected to the end wall 201 (e.g., by welding). It is understood that the above-described second connecting portion 210 is merely exemplary, and any suitable first connecting portion 120 and second connecting portion 210 can be selected according to actual needs to achieve the connection between the fan 100 and the air guide shroud 200. Furthermore, the fastener is not limited to bolts and nuts 211, but may also include, for example, screws, rivets, pins, or clips, etc.

[0034] In some embodiments, combined with Figure 2 and Figure 4 As shown, the connecting component may further include a reinforcing rib 230, with the second connecting portion 210 connected to the reinforcing rib 230. This improves the load-bearing capacity of the air guide shroud 200 and enhances the stability (or robustness) of the fan assembly. In some examples, the reinforcing rib 230 may be independent of the air guide shroud 200. In this case, the reinforcing rib 230 may be positioned above the air guide shroud 200, and the second connecting portion 210 may be connected to the reinforcing rib 230. As an example, in conjunction with Figure 4, the reinforcing rib 230 may include a reinforcing member with an L-shaped cross-section, such as a steel bar with an L-shaped cross-section. This reinforcing member may be positioned above the end wall 201 (e.g., welded to the end wall 201), and may have a second through hole opposite the first through hole 212. Thus, the first connecting portion 120 of the fan 100 can be connected to the reinforcing rib 230 and the air guide shroud 200 via bolts, for example, passing through the first and second through holes.

[0035] In some embodiments, combined with Figure 3 and Figure 4 As shown, the support bracket 220 may include a support portion 221 and a third connecting portion 222. The support portion 221 is located below the air guide shroud 200 and opposite the first notch 205 and the second connecting portion 210. A gap 224 suitable for accommodating the first connecting portion 120 is formed between the support portion 221 and the air guide shroud 200. The bottom end of the third connecting portion 222 is connected to the end of the support portion 221 near the second connecting portion 210, and the top end of the third connecting portion 222 is connected to the air guide shroud 200 to seal the end of the gap 224 near the second connecting portion 210. Thus, the support bracket 220 can not only be connected to the air guide shroud 200 through the third connecting portion 222, but also prevent the first connecting portion 120 from rotating out of the gap 224 during the installation of the fan 100, thereby preventing the fan 100 from falling.

[0036] In some examples, continue to combine Figure 3 and Figure 4As shown, the support bracket 220 can extend along or approximately along the tangent direction of the air inlet 204. This improves the load-bearing capacity of the support bracket 220. As an example, the support portion 221 may include a long strip-shaped first plate that extends along the tangent direction of the air inlet 204. The surface of the first plate can be perpendicular to the end wall 201, and one end of the first plate near the first connecting portion 120 can extend vertically upward to form a second plate. The top of the second plate can be connected to a third plate parallel to the end wall 201 (e.g., formed by bending). The third plate can abut against the end wall 201 and can be connected to the end wall 201, for example, by welding. This allows the support bracket 220 to be securely connected below the air guide shroud 200.

[0037] In some embodiments, the end of the support bracket 220 near the first notch 205 separates from the air guide shroud 200 to form an opening 225, which is adapted to allow the first connecting portion 120 to move out of the gap 224 via the opening 225. In this case, if it is necessary to disassemble the fan 100, the first connecting portion 120 can be detached from the second connecting portion 210, and the first connecting portion 120 can be supported by the support bracket 220 to temporarily support the fan 100 under the air guide shroud 200. Then, the fan 100 is rotated in the opposite direction to that during installation, and the first connecting portion 120 is moved out of the gap 224 via the opening 225 to complete the disassembly of the fan 100. For example, if the fan 100 is rotated clockwise during installation, it is rotated counterclockwise during disassembly.

[0038] In some embodiments, combined with Figure 3 and Figure 4 As shown, the support portion 221 near the first notch 205 has a stop portion 223 protruding towards the air guide shroud 200, forming an opening 225 between the stop portion 223 and the air guide shroud 200 that communicates with the gap 224. During the disassembly of the fan 100, the fan 100 is rotated in the opposite direction to the installation process. After the first connecting portion 120 is rotated to abut against the stop portion 223, the fan 100 needs to be slightly lifted upwards so that the first connecting portion 120 is higher than the stop portion 223. Continuing to rotate the fan 100, the first connecting portion 120 can be rotated out of the gap 224 through the opening 225 to complete the disassembly process. This prevents the fan 100 from falling off the support bracket 220 uncontrollably, thus improving the safety of the fan 100.

[0039] As an example, combined Figure 4As shown, the support portion 221 may include a long strip-shaped first plate, with one end of the first plate near the first notch 205 protruding vertically upward to form a stop portion 223. There may be a certain gap between the top of the protrusion and the end wall 201 to form an opening 225.

[0040] It should be noted that the above-described method for disassembling the fan 100 is merely exemplary. In practical applications, the fan 100 can also be disassembled in the reverse order of its installation. Specifically, the first connecting part 120 can be detached from the second connecting part 210. The fan 100 is rotated, for example, counterclockwise, so that the first connecting part 120 of the fan 100 aligns with the first notch 205. The fan 100 is then lifted vertically upward using, for example, a hoisting device, with the fan body 110 passing through the air inlet 204 and the multiple first connecting parts 120 passing through their respective first notches 205, thereby removing the fan 100 from the air guide cover 200.

[0041] In some examples, combined Figure 2 and Figure 4 As shown, the air inlet 204 can be circular, and the reinforcing rib 230 can extend along the tangent direction of the air inlet 204. This improves the load-bearing capacity of the reinforcing rib 230, thereby enhancing the stability of the fan 100.

[0042] As an example, continue to combine Figure 2 and Figure 4 As shown, a circular air inlet 204 can be provided in the middle of the end wall 201. Four first notches 205 are provided at the four corners near the end wall 201. The second connecting part 210 may include a nut 211 and a first through hole 212 penetrating the end wall 201. The first through hole 212 may be located on one side of the corresponding first notch 205 in a clockwise direction. An L-shaped reinforcing member is provided above the end wall 201 and extends along the tangent direction of the air inlet 204. The reinforcing member may be provided with a second notch 231 opposite to the first notch 205 to avoid the first notch 205. The reinforcing member may also be provided with a second through hole opposite to the first through hole 212 so that it can be connected to the first connecting part 120. The nut 211 may be connected (e.g., welded) above the reinforcing member and opposite to the first through hole 212 and the second through hole.

[0043] Alternatively, the reinforcing rib 230 can also be formed from a portion of the structure of the air guide shroud 200 itself. For example, a groove structure, such as one formed by stamping, can be provided on the periphery of the end wall 201 near the air inlet 204 to form the reinforcing rib 230. Of course, the above-described reinforcing rib 230 is merely exemplary, and the reinforcing rib 230 can also be formed by any other suitable structure.

[0044] The installation process of the fan 100 will be described by way of example below with reference to the accompanying drawings. The disassembly process of the fan 100 will then be described by way of example below with reference to the accompanying drawings. Figures 5 to 9 Perspective views are shown respectively of fan 100 and air guide shroud 200 in different relative positions according to some embodiments of the present disclosure. Figure 5 and Figure 9 The image shows a portion of the compressor housing 300. Figures 6 to 8 The compressor casing 300 is hidden in the middle.

[0045] During the installation of the fan 100, the air guide shroud 200 is first connected laterally to the compressor housing 300. Using hoisting equipment, the fan 100 is lifted above the air guide shroud 200. The fan body 110 is aligned with the air inlet 204, and the multiple first connecting parts 120 are respectively aligned with the multiple first notches 205, as shown below. Figure 5 As shown.

[0046] The height of the fan 100 is gradually lowered, the fan body 110 passes vertically through the air inlet 204, multiple first connecting parts 120 pass vertically through multiple first notches 205, and multiple supporting brackets 220 support the multiple first connecting parts 120, so that the fan 100 is temporarily supported at the air inlet 204. Figure 6 As shown. In this case, the hoisting equipment can be disconnected from the fan 100. At this time, the plurality of first connecting parts 120 are still aligned with their respective first notches 205.

[0047] Slowly rotate the fan 100 clockwise until the plurality of first connecting parts 120 are aligned with their respective second connecting parts 210, for example, until the plurality of lugs of the fan 100 are aligned with the plurality of first through holes 212 formed on the end wall 201. Figure 7 As shown.

[0048] Multiple first connecting parts 120 are respectively connected to their corresponding second connecting parts 210. For example, bolts can be used to pass through the lugs, the first through holes 212 and the second through holes, and then the bolts are connected to the nuts 211 located above the reinforcing ribs 230 to achieve the purpose of connecting the fan 100 and the air guide shroud 200. Figure 1 and Figure 2 As shown. At this time, the multiple first connecting parts 120 may disengage from the multiple supporting brackets 220 respectively. Of course, even if the multiple first connecting parts 120 remain in contact with their respective supporting brackets 220, all or part of the weight of the fan 100 will be directly applied to the air guide shroud 200, and no longer to the supporting brackets 220. That is, the weight of the fan 100 will be directly borne by the air guide shroud 200, and the fan 100 will no longer be supported by the supporting brackets 220.

[0049] During the disassembly of fan 100, combined with Figure 1 , Figure 2 and Figure 7 As shown, firstly, each first connecting part 120 is disconnected from its corresponding second connecting part 210, for example, the bolt can be disconnected from its corresponding nut 211. Then, the height of the fan 100 decreases, and the multiple first connecting parts 120 are respectively attached to their respective supporting brackets 220, which temporarily support the fan 100.

[0050] Rotating the fan 100 counterclockwise, each of the first connecting parts 120 aligns with the corresponding first notch 205, such as... Figure 6 As shown. In this case, one method of disassembly is to use a hoisting device to lift the fan 100, so that the fan body 110 passes vertically upward through the air inlet 204, and so that the multiple first connecting parts 120 pass through their respective corresponding first notches 205, as shown. Figure 5 As shown. The disassembly process of fan 100 in this disassembly method is actually the exact opposite of the fan 100 installation process described above.

[0051] Another way to disassemble is, in Figure 6 In the indicated state, continue rotating the fan 100 counterclockwise until each of the first connecting parts 120 abuts against the stop part 223 of the corresponding support bracket 220. Slightly lift the fan 100 upwards so that the height of the first connecting part 120 is higher than the height of the stop part 223. In this state, continuing to rotate the fan 100 counterclockwise will allow the first connecting part 120 to be rotated out of the gap 224 between the support part 221 and the air guide shroud 200, as shown. Figure 8 As shown.
