[0003] However, most current fan compressor motors typically use a split air intake structure, such as the common louvered air intake structure. The louvered ventilation structure can easily cause direct external radiation of noise from the compressor motor and internal cooling fan, resulting in excessive overall fan noise.

[0030] The embodiments described in this specification will now be described in detail.

[0031] Please refer to Figure 1 and Figure 3 As shown, this application provides an air intake assembly that can be used to reduce the noise generated by a compressor motor connected to the air intake assembly. The air intake assembly includes an air inlet 10, an air inlet channel, and an air outlet 20 connected in sequence. The air blown out through the air outlet 20 is directed towards the compressor motor. The air inlet 10 and the air outlet 20 do not overlap in the axial direction of the compressor motor, and there is at least a misalignment in the vertical and / or horizontal directions.

[0032] The air intake assembly provided in this application, by setting an air inlet 10 and an air outlet 20 that do not overlap in the axial direction of the compressor motor, and by staggering the air outlet 20 and the air inlet 10 in the vertical and / or horizontal directions, provides an additional independent and multi-reflective air intake channel between the compressor motor and the fan air inlet, which can better reduce the noise generated by the compressor motor and provide independent cooling air intake for the compressor motor, thereby improving the heat dissipation efficiency of the compressor motor.

[0033] The air intake assembly connected to the compressor motor provided in this application is only one embodiment. The air intake assembly provided in this application can also be connected to a device installed in the fan that generates a lot of noise or needs air intake during operation, so as to reduce noise and improve heat dissipation efficiency.

[0034] Please refer to Figure 1 and Figure 2 As shown, the air intake assembly includes a first air intake section 30 and a second air intake section 40 connected to each other. The first air intake section 30 is connected to a compressor motor. An air outlet 20 is disposed in the first air intake section 30, and an air inlet 10 is disposed in the second air intake section 40 on the side away from the first air intake section 30.

[0035] The air intake assembly features an interconnected first air intake 30 and a second air intake 30, forming a double-layered sound-absorbing structure. This structure effectively absorbs and isolates noise across different frequency ranges, making it suitable for environments with multiple noise sources and complex conditions. The second air intake 40 absorbs noise, while the first air intake 30 provides sound insulation and isolates noise transmission through cavities between the layers.

[0036] The second air inlet 40 includes a first air inlet branch 41 and a second air inlet branch 42. The second air inlet branch 42 is connected to the first air inlet 30. The first air inlet branch 41 is disposed below the second air inlet branch 42 and is integrally formed with or connected to the second air inlet branch 42. Preferably, the first air inlet branch 41 and the second air inlet branch 42 can be connected by rivets or bolts.

[0037] The first air inlet branch 41 has a first cavity inside, and the second air inlet branch 42 has a second cavity inside. The first cavity and the second cavity are interconnected. The air inlet 10 is located on the side of the first air inlet branch 41 away from the first air inlet section 30.

[0038] By splitting the second air inlet 40 into a first air inlet branch 41 and a second air inlet branch 42, a three-layer air inlet assembly is formed with the first air inlet 30, which can more effectively absorb noise. The noise generated when the compressor motor is working is transmitted from the first air inlet 30, through the second air inlet branch 42, and finally out through the first air inlet branch 41. After being weakened by the three layers of silencing chambers, a good noise reduction effect can be achieved. At the same time, each layer of silencing chamber can provide a more precise sound absorption effect for noise in different frequency ranges, thereby achieving better noise control. In addition, the three-layer air inlet assembly can also reduce the vibration transmission of noise in the direction of noise vibration transmission, thereby effectively reducing noise.

[0039] Please refer to Figure 2 and Figure 4As shown, the second air inlet 40 has an opening on the side away from the first air inlet 30. The second air inlet 40 includes a door panel 43. The door panel 43 closes the opening of the second air inlet 40 and has an air inlet 10. The door panel 43 has two air inlets 10, each including multiple sub-air inlets separated by grilles. The air inlets 10 are located on the lower side of the door panel 43. The door panel 43 connects the first air inlet branch 41 and the second air inlet branch 42.

[0040] Please refer to Figure 2 and Figure 3 As shown, along the axial direction of the compressor motor, the thickness of the first air inlet branch 41 is greater than the thickness of the second air inlet branch 42. At least a portion of the second air inlet branch 42 is located directly above the first air inlet branch 41, and at least a portion of the first air inlet branch 30 is located directly above the first air inlet branch 41. Along the axial direction perpendicular to the compressor motor, the width of the first air inlet branch 41 is greater than the width of the second air inlet branch 42.

[0041] The portion of the first air intake branch 41 that is wider than the second air intake branch 42 forms a reflux cavity, which can reduce the pressure fluctuation of the airflow entering from the air inlet 10 and accelerate the airflow velocity of the cavity at the connection between the first air intake branch 41 and the second air intake branch 42, thereby improving the air intake efficiency of the compressor motor.

[0042] Sound-absorbing material is provided on the inner walls of the first air inlet 30, the second air inlet 40, the air inlet 10, and the air outlet 20. The sound-absorbing material is a porous mineral wool board made of mineral fibers, polyurethane foam, foam glass, porous polyester fiber, or polymer sound-absorbing sponge. Preferably, this application uses a sound-absorbing sponge with a thickness of 25 mm or more and 50 mm or less.

[0043] The air intake assembly provided in this application also includes a seal 50. The seal 50 includes a first seal 51 disposed between the compressor motor and the first air intake section 30 and a second seal 52 disposed between the first air intake section 30 and the second air intake branch 42.

[0044] The sealing element 50 is a component used to enclose a soundproof space and prevent noise transmission. In this application, the first sealing element 51 seals the gap between the compressor motor and the first air inlet 30, and the second sealing element 52 seals the gap between the first air inlet 30 and the second air inlet 40, thereby playing a role in filling and sealing, preventing noise leakage, and resisting the intrusion of moisture, dust and other pollutants.

[0045] The sealing element 50 provided in this application may be made of sealing cotton, including mineral wool, clay wool, polyester fiber wool, spandex wool, or silicone wool. The sealing element 50 may also be made of rubber, polyurethane foam, aluminum sealing strips, sealing rubber strips, or sealing films.

[0046] The air intake assembly includes an air guide vane 21 disposed between the air outlet 20 and the compressor motor. The air guide vane 21 has multiple sub-air outlets, which are connected to the air outlet 20.

[0047] Please refer to Figure 5 and Figure 6 As shown, the air guide vane 21 includes a main air guide vane 211 and multiple auxiliary air guide vanes 212. The main air guide vane 211 is located in the middle of the air outlet 20, and the multiple auxiliary air guide vanes 212 are located on the upper and lower sides of the main air guide vane 211. The auxiliary air guide vanes 212 located above the main air guide vane 211 have an inclination direction opposite to that of the auxiliary air guide vanes 212 located below the main air guide vane 211. The thickness of the auxiliary air guide vanes 212 is greater than or equal to 1.5 mm and less than or equal to 2 mm. A sound-absorbing part with a thickness of greater than or equal to 25 mm and less than or equal to 50 mm is provided on the side of the auxiliary air guide vane 212 facing the compressor motor. The sound-absorbing part is made of polymer sound-absorbing sponge.

[0048] Please refer to Figure 7 As shown, this application provides another embodiment in which the air guide vane 21 divides the air outlet 20 into multiple sub-air outlets. The air guide vane 21 has a zigzag structure and is evenly distributed at the air outlet 20, thereby forming a louvered air inlet channel.

[0049] Please refer to Figure 8 As shown, this application provides another embodiment. In this embodiment, the main air guide 211 is disposed in the middle of the air outlet 20 and is conical. A plurality of secondary air guides 212 are in the form of a ring and are arranged around the main air guide 211 with the main air guide 211 as the center.
