[0040] The embodiments of the present application provide a fan guide rail, an air duct assembly, and an electrical device to reduce vibration of the fan and the air duct, thereby reducing the probability of resonance between the fan and the air duct.

[0041] To facilitate understanding of the solution, the electrical equipment and air duct components are first described in detail below.

[0042] The electrical device provided in the embodiments of the present application may be a power electronic device or other electrical device. For example, the electrical device is a power converter. The embodiments of the present application do not limit the type of electrical device.

[0043] like Figure 1 As shown, the electrical device 100 includes an electrical device body 6 and an air duct assembly 10 arranged on the electrical device body 6 .

[0044] The electrical equipment body 6 may include a housing (not shown in the figure) and components (not shown in the figure) disposed in the housing, and the air duct assembly 10 may be disposed on the housing.

[0045] The air duct assembly 10 is used to dissipate heat from the electrical device body 6. The air duct assembly 10 includes: an air duct 1, a fan bracket 2, a fan 3 and a fan guide rail 4.

[0046] Air duct 1 is a heat dissipation duct. It can be fixed to the electrical device body 6, communicating with the interior of the housing of the electrical device body 6. To facilitate installation and removal, the air duct 1 and the housing of the electrical device body 6 are removably fixedly connected. Exemplarily, the air duct 1 and the housing are removably fixedly connected using fasteners or a snap-fit ​​structure.

[0047] The specific structure and shape of the air duct 1 are designed according to actual conditions and are not limited in this embodiment of the present application.

[0048] The fan guide rail 4 is fixed to the air duct 1. In order to reduce noise, the fan guide rail 4 and the air duct 1 are welded or riveted. Of course, the fan guide rail 4 can also be fixed to the air duct 1 in other ways.

[0049] The fan bracket 2 and the fan guide rail 4 are slidably matched, the fan bracket 2 and the air duct 1 are fixedly connected, and the fan 3 is fixed to the fan bracket 2. It should be noted that the fan bracket 2 and the fan 3 can both be understood as part of the fan assembly.

[0050] During installation, the fan bracket 2 slides from one end of the fan guide rail 4 into the fan guide rail 4, that is, into the air duct 1. After the fan bracket 2 slides to a set position, the fan bracket 2 is fixed in the air duct 1.

[0051] In order to facilitate installation and removal, the fan bracket 2 and the air duct 1 are detachably fixedly connected by fasteners, which also facilitates installation, removal, maintenance and repair of the fan 3. Exemplarily, the fan bracket 2 and the air duct 1 are detachably fixedly connected by screws 5.

[0052] The fan 3 is welded to the fan bracket 2, or the fan 3 is fixed to the fan bracket 2 by fasteners, or the fan 3 is fixed to the fan bracket 2 by other means, which is not limited in the embodiment of the present application.

[0053] In actual situations, the air duct assembly 10 may also not include the fan bracket 2 and the fan 3, and is not limited to Figure 1 The structure shown.

[0054] To facilitate the following description, a coordinate system is established. The axial direction of fan 3 is defined as the first direction, a direction perpendicular to the axial direction of fan 3 is defined as the second direction, and another direction perpendicular to the axial direction of fan 3 is defined as the third direction. It is understood that the first direction is perpendicular to the second direction, and both the first and second directions are perpendicular to the third direction. For example, the first direction is horizontal and the second direction is vertical; alternatively, the first direction is vertical and the second direction is horizontal.

[0055] In the second direction, the fan rails 4 are distributed on both sides of the air duct 1; both ends of the fan bracket 2 in the second direction are slidably engaged with the fan rails 4. Of course, in the second direction, the fan rails 4 can be distributed on one side of the air duct 1, and one end of the fan bracket 2 in the second direction is slidably engaged with the fan rails 4.

[0056] The structure of the fan rail 4 will be described in detail below.

[0057] like Figure 2-Figure 4 As shown, the fan guide rail 4 includes a guide rail 41 and a vibration damping member 42 .

[0058] The guide rail 41 can be made of aluminum alloy or carbon steel to maintain the strength of the fan guide rail 4. The guide rail 41 has a groove 413 to ensure that the fan guide rail 4 accommodates the fan bracket 2, and the fan guide rail 4 and the fan bracket 2 are slidably matched.

[0059] It should be noted that the width direction of the groove 413 is the first direction, the depth direction of the groove 413 is the second direction, and the length direction of the groove 413 is the third direction.

[0060] like Figure 4 As shown, in some embodiments, the guide rail 41 includes a first guide rail plate a and two second guide rail plates b, wherein one second guide rail plate b, the first guide rail plate a, and the other second guide rail plate b are sequentially connected to form a groove 413. It should be noted that the first guide rail plate a and the second guide rail plate b are perpendicular to each other, or the first guide rail plate a and the second guide rail plate b are inclined relative to each other, which can be understood as: an angle is formed between the first guide rail plate a and the second guide rail plate b.

[0061] Exemplarily, in the second direction, the two second guide rail plates b are located on the same side of the first guide rail plate a, the two second guide rail plates b are distributed along the first direction, one second guide rail plate b is connected to one end of the first guide rail plate a, and the other second guide rail plate b is connected to the other end of the first guide rail plate a.

[0062] The first guide rail plate a and the two second guide rail plates b may be an integrated structure or a split structure.

[0063] In other embodiments, the guide rail 41 may also have other structures and is not limited to the above embodiment.

[0064] Continue to refer Figure 4 The surface of the guide rail 41 may include an inner wall 411 and an outer wall 412, wherein the inner wall 411 forms a groove 413, and the outer wall 412 is located outside the groove 413. It can be understood that the inner wall 411 is the groove wall of the groove 413.

[0065] As mentioned above, the guide rail 41 includes a first guide rail plate a and two second guide rail plates b, the inner wall 411 includes the inner plate surface of the first guide rail plate a and the inner plate surface of the second guide rail plate b, and the outer wall 412 includes the outer plate surface of the first guide rail plate a and the outer plate surface of the second guide rail plate b.

[0066] The groove walls of groove 413 include a first groove wall a1 and two second groove walls b1. The first groove wall a1 can be understood as the inner surface of the first guide plate a, and the second groove wall b1 can be understood as the inner surface of the second guide plate b. Accordingly, the inner wall 411 can be understood as including the first groove wall a1 and the second groove wall b1. It should be noted that the first groove wall a1 and the second groove wall b1 are arranged along the first direction and are perpendicular or relatively inclined to each other, which can be understood as: the first groove wall a1 and the second groove wall b1 have an angle therebetween.

[0067] The guide rail 41 is fixed to the air duct 1. In order to reduce noise, the guide rail 41 and the air duct 1 are welded or riveted. Of course, the guide rail 41 can also be fixed to the air duct 1 in other ways.

[0068] In order to facilitate the fixed connection between the guide rail 41 and the air duct 1, the first guide rail plate a of the guide rail 41 can be selected to be fixedly connected to the air duct 1. In actual practice, other parts of the guide rail 41 can also be selected to be fixedly connected to the air duct 1, and this embodiment of the application does not limit this.

[0069] Vibration dampers 42 are provided on guide rails 41, providing fan guide rails 4 with a vibration-damping function. Since vibrations from fan 3 and fan bracket 2 are transmitted to air duct 1 via fan guide rails 4, vibration dampers 42 can reduce the vibrations transmitted to air duct 1 by fan 3 and fan bracket 2, thereby reducing the vibration of air duct 1 and the noise generated by the vibration of air duct 1.

[0070] Correspondingly, the vibration damper 42 can also reduce the vibration of the fan 3 and the fan bracket 2, as well as reduce the noise generated by the vibration of the fan 3 and the fan bracket 2; since the vibration damper 42 reduces the vibration of the air duct 1, the fan 3 and the fan bracket 2, the vibration damper 42 also reduces the probability of resonance between the fan 3 and the air duct 1.

[0071] The fan guide rail 4 reduces the vibration of the fan 3 and the fan bracket 2 , effectively improves the stability of the fan 3 during operation, and extends the service life of the fan 3 .

[0072] In actual situations, after the electrical equipment using the above-mentioned fan guide rail 4 has been running for a long time, if the noise of the fan 3 becomes louder, the corresponding noise problem can be solved directly by replacing the fan guide rail 4, which reduces the difficulty of solving the noise problem.

[0073] It should be noted that, since the fan guide rail 4 is fixed to the air duct 1, in order to facilitate replacement of the fan guide rail 4, the air duct 1 and the fan guide rail 4 can be replaced together. Based on this, a detachable fixed connection is required between the air duct 1 and the electrical equipment body 6.

[0074] The relative positions of the vibration damper 42 and the guide rail 41 are designed based on actual needs. As previously mentioned, the fan guide rail 4 and the fan bracket 2 are slidably fitted together. To effectively reduce the vibration transmitted from the fan 3 and the fan bracket 2 to the fan guide rail 4, the vibration damper 42 is positioned within the groove 413, or a portion of the vibration damper 42 is positioned within the groove 413. This allows the vibration damper 42 to directly contact the fan guide rail 4, enhancing the vibration damping effect of the vibration damper 42.

[0075] Of course, the vibration damping member 42 may also be located outside the groove 413 and is not limited to the above distribution method.

[0076] The fan bracket 2 is located in the fan guide rail 4. The first groove wall a1 and the second groove wall b1 of the groove 413 both correspond to the fan bracket 2. Based on this, Figure 5-Figure 8 As shown, the vibration damper 42 can be distributed on at least the first guide rail plate a and the second guide rail plate b of the guide rail 41, so that the vibration damper 42 can be in direct contact with the fan bracket 2; or, the first groove wall a1 and the two second groove walls b1 of the groove 413 both correspond to the fan bracket 2. Based on this, the vibration damper 42 can be distributed on the first guide rail plate a and the two second guide rail plates b of the guide rail 41, so that the vibration damper 42 can be in direct contact with the fan bracket 2. In this case, since the first groove wall a1 and the second groove wall b1 are distributed along the first direction, the depth direction of the groove 413 is the second direction, and the second direction is perpendicular to the first direction, the vibration damping member 42 corresponding to the first groove wall a1 and the two second groove walls b1 can reduce the vibration of the fan 3, the fan bracket 2 and the air duct 1 in the first direction and the second direction. Since the first direction is the axial direction of the fan 3, the vibration damping member 42 can reduce the vibration of the fan 3, the fan bracket 2 and the air duct 1 in the axial direction of the fan 3, as well as the vibration in the direction perpendicular to the axial direction of the fan 3, thereby further reducing the vibration of the fan 3, the fan bracket 2 and the air duct 1.

[0077] The above-mentioned fan guide rail 4 reduces the vibration of the fan 3 in the first direction and the second direction, effectively improves the stability of the fan 3 during operation, and extends the service life of the fan 3; it also reduces the vibration transmitted from the fan 3 to the air duct 1, and reduces the possibility of resonance between the fan 3, the fan bracket 2, the fan guide rail 4 and the air duct 1.

[0078] The specific structure of the vibration damper 42 is selected according to actual conditions. The vibration damper 42 can be a buffer elastic member, for example, a rubber member, a silicone member, or a plastic member; the vibration damper 42 can be other vibration damping structures.

[0079] In some embodiments, the vibration damper 42 includes at least one of a buffer layer 421 and a vibration absorber 422 . The buffer layer 421 at least covers a portion of the guide rail 41 , and the vibration absorber 422 is disposed on the guide rail 41 .

[0080] Exemplarily, the vibration damper 42 includes a buffer layer 421, which covers at least a portion of the guide rail 41; or, the vibration damper 42 includes a vibration damper 422, which is disposed on the guide rail 41; or, the vibration damper 42 includes a buffer layer 421 and a vibration damper 422, which covers at least a portion of the guide rail 41, and the vibration damper 422 is disposed on the guide rail 41. Figure 2-Figure 8 As shown, in order to effectively improve the vibration reduction effect of the vibration reduction member 42 , the vibration reduction member 42 may include a buffer layer 421 and a vibration absorber 422 .

[0081] In the above embodiment, by providing the buffer layer 421, the assembly gap between the fan guide rail 4 and the fan bracket 2 can be reduced, thereby reducing the vibration of the fan bracket 2 and the fan 3, and reducing the vibration of the air duct 1; at the same time, the buffer layer 421 can also reduce the vibration transmitted to the air duct 1 by the fan bracket 2 and the fan 3, thereby reducing the vibration of the air duct 1.

[0082] In the above embodiment, by providing a vibration damper 422, the vibration transmitted to the air duct 1 by the fan bracket 2 and the fan 3 is reduced by the vibration damper 422, thereby reducing the vibration of the air duct 1; moreover, by providing a buffer layer 421 and a vibration damper 422, the vibration of the air duct 1, as well as the vibration of the fan bracket 2 and the fan 3 can be reduced under the dual action of the buffer layer 421 and the vibration damper 422.

[0083] The buffer layer 421 will be described below.

[0084] The buffer layer 421 may be a rubber layer, a silicone layer, a plastic layer, etc., which is not limited in this embodiment of the present application.

[0085] As described above, the entire vibration damper 42 is located in the groove 413 or a portion of the vibration damper 42 is located in the groove 413 . Based on this, the entire buffer layer 421 is located in the groove 413 or a portion of the buffer layer 421 is located in the groove 413 .

[0086] In some embodiments, as Figure 5-Figure 8 As shown, in order to effectively improve the vibration reduction effect of the buffer layer 421 , the buffer layer 421 at least covers the inner wall 411 of the guide rail 41 .

[0087] For example, the first groove wall a1 and the second groove wall b1 of the groove 413 correspond to the fan bracket 2, and the buffer layer 421 covers the first groove wall a1 and the second groove wall b1 of the groove 413. This can be understood as the buffer layer 421 covering a portion of the inner wall 411 of the guide rail 41. In this way, the buffer layer 421 can reduce vibration of the fan 3, the fan bracket 2, and the air duct 1 in both the first and second directions, thereby enhancing the vibration reduction effect of the buffer layer 421.

[0088] For example, the first groove wall a1 and the two second groove walls b1 of the groove 413 correspond to the fan bracket 2, and the buffer layer 421 covers the first groove wall a1 and the two second groove walls b1 of the groove 413. This can be understood as: the buffer layer 421 covers the entire inner wall 411 of the guide rail 41. In this way, the buffer layer 421 can reduce the vibration of the fan 3, the fan bracket 2, and the air duct 1 in the first and second directions, thereby improving the vibration reduction effect of the buffer layer 421.

[0089] Exemplarily, the buffer layer 421 covers the inner wall 411 of the guide rail 41 , and the buffer layer 421 covers a portion of the outer wall 412 of the guide rail 41 , or the buffer layer 421 covers both the inner wall 411 and the outer wall 412 of the guide rail 41 .

[0090] like Figure 5-Figure 8 As shown, in order to reserve a connection position between the guide rail 41 and the air duct 1, a buffer layer 421 can be selected to cover the inner wall 411 of the guide rail 41, and the buffer layer 421 covers a portion of the outer wall 412 of the guide rail 41, with the other portion of the outer wall 412 of the guide rail 41 exposed outside the buffer layer 421. In this way, the buffer layer 421 can reduce the vibration of the fan 3, the fan bracket 2, and the air duct 1 in the first and second directions, thereby improving the vibration reduction effect of the buffer layer 421. Moreover, the buffer layer 421 covers a larger area of ​​the guide rail 41, and the vibration reduction effect of the buffer layer 421 is better. At the same time, the other portion of the outer wall 412 of the guide rail 41 exposed outside the buffer layer 421 can be fixedly connected to the air duct 1, facilitating the fixed connection between the fan guide rail 4 and the air duct 1.

[0091] Continue to refer Figure 5-Figure 8 The buffer layer 421 has a first buffer layer end 4211 and a second buffer layer end 4212, and the first buffer layer end 4211 and the second buffer layer end 4212 are sequentially distributed along the first direction. The positions of the first buffer layer end 4211 and the second buffer layer end 4212 in the second direction are selected according to actual conditions. Exemplarily, the end surface of the first buffer layer end 4211 and the end surface of the second buffer layer end 4212 are both flush with the outer plate surface of the first guide rail plate a, or the end surface of the first buffer layer end 4211 and the end surface of the second buffer layer end 4212 are both at a preset distance from the outer plate surface of the first guide rail plate a.

[0092] In some embodiments, the first end 4211 and the second end 4212 of the buffer layer are both located on the second guide rail plate b, and the buffer layer 421 extends along a plane on the second guide rail plate b. This makes it more likely that the first end 4211 and the second end 4212 of the buffer layer will be flanged.

[0093] In other embodiments, to reduce the probability of flange formation at the first end 4211 and the second end 4212 of the buffer layer, a notch 414 is provided on the outer wall of the guide rail 41. This notch 414 can be understood as being located outside the groove 413. Notches 414 are located on both sides of the groove 413 in the first direction. Both the first end 4211 and the second end 4212 of the buffer layer are located within the notch 414. Exemplarily, notch 414 is located in the first guide rail plate a; alternatively, notch 414 is located at the junction of the first guide rail plate a and the second guide rail plate b; alternatively, notch 414 is located in the second guide rail plate b.

[0094] In the above embodiment, the first end 4211 of the buffer layer cooperates with the notch 414 and the second end 4212 of the buffer layer cooperates with the notch 414, thereby reducing the probability of flanging of the first end 4211 of the buffer layer and the second end 4212 of the buffer layer.

[0095] To further reduce the probability of flange formation, the notch 414 is located at the end of the guide rail 41 that is away from the notch of the groove 413. In this way, the first end 4211 and the second end 4212 of the buffer layer can be located between the guide rail 41 and the air duct 1, further reducing the probability of flange formation at the first end 4211 and the second end 4212 of the buffer layer.

[0096] Next, the shock absorber 422 will be described.

[0097] The vibration absorber 422 can be a piezoelectric vibration absorber, a damping vibration absorber, an air vibration absorber, or a magnetic flow vibration absorber, etc. In order to improve the vibration reduction effect of the vibration absorber 422, the vibration absorber 422 can be selected as a piezoelectric vibration absorber. Moreover, the piezoelectric vibration absorber is smaller in size and is easy to adapt to the smaller fan guide rail 4.

[0098] In some embodiments, as Figure 5-Figure 7 As shown, the vibration damper 422 is located on the inner wall 411 of the guide rail 41. Since the fan bracket 2 and the fan guide rail 4 cooperate, the vibration damper 422 is arranged close to the fan bracket 2, thereby improving the vibration reduction effect of the vibration damper 422 on the fan bracket 2 and the fan 3.

[0099] like Figure 5-Figure 7As shown, the inner wall 411 of the guide rail 41 may be provided with a first recessed portion 4111, and the vibration damper 422 is located within the first recessed portion 4111. This can be understood as the vibration damper 422 being embedded in the guide rail 41. The vibration damper 422 and the first recessed portion 4111 are flush with each other, thus reducing the impact of the vibration damper 422 on the surface of the guide rail 41.

[0100] like Figure 7 As shown, the first recessed portion 4111 does not extend to the outer wall 412 of the guide rail 41, and there is a preset distance between the shock absorber 422 and the outer wall 412 of the guide rail 41. Figure 5 and Figure 6 As shown, the first recessed portion 4111 extends to the outer wall 412 of the guide rail 41 , and the shock absorber 422 also extends to the outer wall 412 of the guide rail 41 .

[0101] In actual situations, the shock absorber 422 may also protrude from the first recessed portion 4111 or be sunken into the first recessed portion 4111 . This may also reduce the impact of the shock absorber 422 on the surface of the guide rail 41 .

[0102] In actual situations, the inner wall 411 of the guide rail 41 may not be provided with the first recessed portion 4111 , and the entire shock absorber 422 protrudes from the inner wall 411 .

[0103] In some other embodiments, the vibration damper 422 is located on the outer wall 412 of the guide rail 41. Since the fan guide rail 4 is disposed in the air duct 1, the vibration damper 422 is disposed close to the air duct 1, thereby improving the vibration damping effect of the vibration damper 422 on the air duct 1.

[0104] like Figure 5 and Figure 6 As shown, the outer wall 412 of the guide rail 41 can be provided with a second recessed portion 4121, and the vibration damper 422 is located in the second recessed portion 4121. This can be understood as the vibration damper 422 being embedded in the guide rail 41. The vibration damper 422 and the second recessed portion 4121 are arranged flush. This reduces the impact of the vibration damper 422 on the surface of the guide rail 41.

[0105] like Figure 5 and Figure 6 As shown, the second recessed portion 4121 extends to the inner wall 411 of the guide rail 41, and the vibration absorber 422 also extends to the inner wall 411 of the guide rail 41. Of course, it is also possible to choose that the second recessed portion 4121 does not extend to the inner wall 411 of the guide rail 41, and there is a preset distance between the vibration absorber 422 and the inner wall 411 of the guide rail 41.

[0106] It should be noted that the first recessed portion 4111 extends to the outer wall 412 of the guide rail 41, which can be understood as: in the distribution direction of the inner wall 411 and the outer wall 412 of the guide rail 41, the first recessed portion 4111 penetrates the guide rail 41, and the shock absorber 422 can also penetrate the guide rail 41; the second recessed portion 4121 extends to the inner wall 411 of the guide rail 41, which can be understood as: in the distribution direction of the inner wall 411 and the outer wall 412 of the guide rail 41, the second recessed portion 4121 penetrates the guide rail 41, and the shock absorber 422 can also penetrate the guide rail 41.

[0107] When the first recess 4111 extends to the outer wall 412 of the guide rail 41 and the second recess 4121 extends to the inner wall 411 of the guide rail 41, the first recess 4111 and the second recess 4121 can be understood as the same recess, and the vibration damper 422 is located on both the inner wall 411 and the outer wall 412 of the guide rail 41, which can be understood as: the vibration damper 422 penetrates the guide rail 41. In this way, the vibration damper 422 is located near both the fan bracket 2 and the air duct 1, effectively reducing the vibration transmitted to the air duct 1 by the fan 3 and the fan bracket 2, and improving the vibration reduction effect of the vibration damper 422.

[0108] In actual situations, the shock absorber 422 may also protrude from the second recessed portion 4121 or be sunken into the second recessed portion 4121 . This can also reduce the impact of the shock absorber 422 on the surface of the guide rail 41 .

[0109] In actual situations, the outer wall 412 of the guide rail 41 may not be provided with the second recessed portion 4121 , and the entire shock absorber 422 may protrude from the outer wall 412 .

[0110] In actual practice, the vibration absorbers 422 may be located on both the inner wall 411 and the outer wall 412 of the guide rail 41. In addition to the aforementioned arrangement where the vibration absorbers 422 penetrate the guide rail 41 in the distribution direction of the inner wall 411 and the outer wall 412 of the guide rail 41, it is also possible to arrange a portion of the vibration absorbers 422 only on the inner wall 411 and another portion only on the outer wall 412.

[0111] In some other embodiments, such as Figure 8 As shown, the vibration damper 422 is located between the outer wall 412 and the inner wall 411 of the guide rail 41. In this way, the vibration of the fan 3 and the fan bracket 2 can be transmitted to the vibration damper 422 through the guide rail 41, and the vibration damper 422 reduces the vibration, thereby reducing the vibration transmitted to the air duct 1 by the fan 3 and the fan bracket 2.

[0112] The specific position of the shock absorber 422 on the guide rail 41 is selected according to the actual situation. Figure 6-Figure 8As shown, when both first groove wall a1 and second groove wall b1 of groove 413 correspond to fan bracket 2, vibration damper 422 corresponds to first groove wall a1 and second groove wall b1 of groove 413. This can be understood as vibration damper 422 being distributed on first guide plate a and second guide plate b. In this way, vibration damper 422 can reduce vibration of fan 3, fan bracket 2, and air duct 1 in both the first and second directions, thereby enhancing the vibration reduction effect of vibration damper 422.

[0113] When the first groove wall a1 and the two second groove walls b1 of the groove 413 correspond to the fan bracket 2, the vibration damper 422 corresponds to the first groove wall a1 and the two second groove walls b1 of the groove 413. This can be understood as: the vibration damper 422 is distributed on the first guide plate a and the two second guide plates b. In this way, the vibration damper 422 can reduce the vibration of the fan 3, the fan bracket 2, and the air duct 1 in the first direction and the second direction, thereby improving the vibration reduction effect of the vibration damper 422.

[0114] In order to facilitate the correspondence between the vibration damper 422 and the first groove wall a1 and the second groove wall b1, the vibration damper 422 includes a first vibration damper 4221 and a second vibration damper 4222. The first vibration damper 4221 corresponds to the first groove wall a1, and the second vibration damper 4222 corresponds to the second groove wall b1. Figure 6 and Figure 8 As shown, the first shock absorber 4221 and the second shock absorber 4222 can be a split structure; or, as shown in FIG. Figure 7 As shown, 4221 and the second shock absorber 4222 are an integrated structure.

[0115] It should be noted that the position of the first shock absorber 4221 on the guide rail 41 can refer to the position of the shock absorber 422 on the guide rail 41 mentioned above; the position of the second shock absorber 4222 on the guide rail 41 can refer to the position of the shock absorber 422 on the guide rail 41 mentioned above. The positions of the first shock absorber 4221 and the second shock absorber 4222 on the guide rail 41 are independent of each other and do not affect each other. Exemplarily, the first shock absorber 4221 and the second shock absorber 4222 are both located on the inner wall 411 of the guide rail 41; or, the first shock absorber 4221 and the second shock absorber 4222 are both located on the outer wall 412 of the guide rail 41; or, of the first shock absorber 4221 and the second shock absorber 4222, one is located on the inner wall 411 of the guide rail 41 and the other is located on the outer wall 412 of the guide rail 41; or, the first shock absorber 4221 and the second shock absorber 4222 both pass through the guide rail 41.

[0116] In actual situations, if Figure 5As shown, the vibration damper 422 may also be selected to correspond to the first groove wall a1 of the groove 413. It can be understood that the vibration damper 422 is distributed on the first guide rail plate a, so that the vibration damper 422 can reduce the vibration of the fan 3, fan bracket 2 and air duct 1 in the second direction.

[0117] In practical applications, the vibration damper 422 can also be aligned with the second groove wall b1 of the groove 413. This can be understood as follows: the vibration damper 422 is distributed on the second guide plate b. For example, the vibration damper 422 is distributed on one or two second guide plates b. In this way, the vibration damper 422 can reduce the vibration of the fan 3, the fan bracket 2, and the air duct 1 in the first direction.

[0118] The above description about the vibration damper 422 can be applied to the case where the vibration damper 42 includes the buffer layer 421 , and can also be applied to the case where the vibration damper 42 does not include the buffer layer 421 .

[0119] The following describes the relative positional relationship between the buffer layer 421 and the vibration absorber 422 according to an embodiment in which the vibration damping member 42 includes a vibration absorber 422 and a buffer layer 421. In some embodiments, as Figure 5-Figure 8 As shown, the buffer layer 421 covers at least a portion of the vibration absorber 422 .

[0120] For example, the buffer layer 421 covers at least a portion of the inner wall 411 of the guide rail 41, and the shock absorber 422 is located on the inner wall 411 of the guide rail 41. Figure 5-Figure 7 As shown, the buffer layer 421 can cover the portion of the inner wall 411 of the guide rail 41 that covers the entire shock absorber 422; or the portion of the inner wall 411 of the guide rail 41 that covers the buffer layer 421 can cover a portion of the shock absorber 422. The buffer layer 421 covers at least a portion of the outer wall 412 of the guide rail 41, and the shock absorber 422 is located on the outer wall 412 of the guide rail 41. Figure 6 As shown, the buffer layer 421 can cover a portion of the outer wall 412 of the guide rail 41 and a portion of the shock absorber 422 ; or, the buffer layer 421 can cover a portion of the outer wall 412 of the guide rail 41 and the entire shock absorber 422 .

[0121] In some other embodiments, the buffer layer 421 does not cover the vibration damper 422. For example, the buffer layer 421 and the vibration damper 422 are respectively located at different positions on the inner wall 411 of the guide rail 41; or, the buffer layer 421 and the vibration damper 422 are respectively located at different positions on the outer wall 412 of the guide rail 41; or, one of the buffer layer 421 and the vibration damper 422 is located on the inner wall 411 of the guide rail 41 and the other is located on the outer wall 412 of the guide rail 41; or, the vibration damper 422 is located between the inner wall 411 and the outer wall 412 of the guide rail 41. In this case, the buffer layer 421 is randomly distributed.

[0122] Since the fan guide rail 4 provided in the above embodiment has the above technical effects, the air duct assembly 10 and the electrical device 100 provided in the above embodiment also have corresponding technical effects, which will not be described in detail here.

[0123] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
