Definitions

  • the disclosure relates to a fan device, and more particularly to a fan device having a casing body and a porous plate to define a noise-reduction room.
  • auxiliary noise-reduction devices have been developed to be used with the fan, as disclosed for example in GB2284448 A .
  • a conventional noise-reduction fan assembly includes a fan 10 and a noise-reduction device 1 mounted to the fan 10.
  • the noise-reduction device 1 includes a casing 11 connected to the fan 10, a plurality of drivenable fan blades 12, a surrounding plate 13, and a sound-absorbing member 14.
  • the casing 11 defines an inner space 110.
  • the drivenable fan blades 12 are made of a sound-absorbing material and disposed in the inner space 110.
  • the surrounding plate 13 is disposed in the inner space 110 and divides the inner space 110 into a central room 132 for receiving the drivenable fan blades 12 and a sound-absorbing room 130 surrounding the central room 132.
  • the sound-absorbing member 14 is filled in the sound-absorbing room 130.
  • the surrounding plate 13 has a plurality of through holes 131 to spatially communicate the central room 132 with the sound-absorbing room 130. Airflow generated by the fan 10 will drive rotation of the drivenable fan blades 12 and then the airflow will be guided into the central room 132. The airflow is also guided from the central room 132 into the sound-absorbing room 130 through the through holes 131 of the surrounding plate 13. The noise generated by the fan 10 can be partially absorbed by the drivenable fan blades 12 and partially absorbed by the noise-absorbing member 14 filled in the sound-absorbing room 130.
  • the aforementioned conventional noise-reduction fan assembly requires installation of the drivenable fan blades 12, and the drivenable fan blades 12 are required to be adjusted based on a few parameters of the fan 10, such as rotational performance and an integral structural configuration.
  • the design and manufacturing of the conventional noise-reduction device 1 is relatively complicated.
  • another conventional noise-reduction fan assembly includes a fan 20 and a noise-reduction device 2 connected to the fan 20.
  • the noise-reduction device 2 includes a resonator 21 and a status indication unit 220.
  • the fan 20 is exemplified to be a heat-dissipating fan for dissipating heat of an electronic apparatus, such as a central processing unit 22.
  • the status indication unit 220 is connected between the resonator 21 and the central processing unit 22, and is capable of indicating an operational status of the central processing unit 22.
  • the resonator 21 includes a casing 211 that defines an inner chamber 210 in spatial communication with the fan 20, a clapboard 212, an elastic component 213, and two thermoelectric components 214 capable of detecting noise through noise-responsive deformation.
  • the clapboard 212 is disposed in the inner chamber 210, and divides the inner chamber 210 into a space 201 in spatial communication with the fan 20 and a resonance room 200.
  • the elastic component 213 is received in the resonance room 200 and is connected to the clapboard 212 and the casing 211 so that the clapboard 212 is movable relative to the casing 211.
  • thermoelectric components 214 are disposed in the resonance room 200 and located respectively on two symmetrical sides of the clapboard 212.
  • the thermoelectric component 214 is in signal communication with the status indication unit 220 and is deformable accordingly. Deformation of the thermoelectric components 214 will move the clapboard 212 to adjust a resonance volume of the resonance room 200 so as to eliminate the noise generated by the fan 20.
  • the aforementioned conventional noise-reduction fan assembly also has complicated structure and signal communication. Hence, there is plenty of room for improvement in the structural design of the conventional noise-reduction fan assembly.
  • an object of the disclosure is to provide a fan device that can alleviate at least one of the drawbacks of the prior art.
  • a fan device includes a casing unit and a fan impeller unit mounted in the casing unit.
  • the casing unit has an axis and includes a casing body, a porous plate, and an air-entering tube.
  • the casing body is formed with a receiving space and an air outlet port in spatial communication with the receiving space.
  • the porous plate is formed with a plurality of through holes and is disposed in the receiving space to divide the receiving space into an air-flowing room and a noise-reduction room aligned with and spaced apart from each other along the axis.
  • the air-entering tube is connected to the casing body and is in spatial communication with the air-flowing room.
  • the fan impeller unit is disposed in the air-flowing room of the receiving space and is rotatable about the axis to generate airflow that partially flows from the air-flowing room into the noise-reduction room through the through holes of the porous plate.
  • a first embodiment of a fan device includes a casing unit 3 and a fan impeller unit 4 that is mounted in the casing unit 3.
  • the casing unit 3 has an axis (A) and includes a casing body 31, a porous plate 32, an air-entering tube 33, and an air guiding member 34.
  • the casing body 31 is formed with a receiving space 310 and an air outlet port 318 in spatial communication with the receiving space 310.
  • the casing body 31 of the casing unit 3 includes a base 312 and a cover 311 connected to the base 312 to cooperatively define the receiving space 310.
  • the porous plate 32 is formed with a plurality of through holes 329 and is disposed in the receiving space 310 to divide the receiving space 310 into an air-flowing room 301 and a noise-reduction room 302 aligned with and spaced apart from each other along the axis (A).
  • the base 312 cooperates with the porous plate 32 to define the noise-reduction room 302.
  • the cover 311 cooperates with the porous plate 32 to define the air-flowing room 301.
  • the porous plate 32 is further formed with an inner tube-communicating through hole 321 spaced apart from the through holes 329.
  • the air-entering tube 33 is connected to the casing body 31 and is in spatial communication with the air-flowing room 301.
  • the air-entering tube 33 peripherally and outwardly extends from and is in spatial communication with the inner tube-communicating through hole 321.
  • the air guiding member 34 is disposed at the air outlet port 318 of the casing body 31 and is in spatial communication with the receiving space 310 of the casing body 31.
  • the air guiding member 34 may peripherally protrude from the air outlet port 318 of the casing body 31 and tapered along a direction away from the casing body 31, such that an airflow flowing through the air guiding member 34 can be collectively pressurized to have an increased air pressure.
  • the fan impeller unit 4 is disposed in the air-flowing room 301 of the receiving space 310 and is rotatable about the axis (A) to generate an airflow that partially flows from the air-flowing room 301 into the noise-reduction room 302 through the through holes 329 of the porous plate 32.
  • the fan impeller unit 4 when the fan impeller unit 4 is in operation, ambient air is guided into the air-flowing room 301 through the air-entering tube 33 and the inner tube-communicating through hole 321 of the porous plate 21.
  • the airflow is generated from the air flowing into the air-flowing room 301.
  • a main stream of the airflow mainly flows from the air-flowing room 301 toward the air outlet port 318.
  • a tributary of the airflow flows from the air-flowing room 301 into the noise-reduction room 302 through the through holes 329 of the porous plate 32.
  • the configuration of the casing unit 3, such as the shape and the internal volume of the noise-reduction room 302 is designed in accordance with the noise frequency of the fan impeller unit 4.
  • the airflow flowing into the noise-reduction room 302 through the through holes 329 of the porous plate 32 is dispersed by the through holes 329 before entering the noise-reduction room 302, so that wind shear produced and concentrated at a certain position can be avoided to reduce the noise.
  • the fan device of the second embodiment further includes a sound-absorption member 5 disposed in the noise-reduction room 302.
  • the sound-absorption member 5 is porous.
  • the noise is further absorbed by the sound-absorption member 5.
  • the volume and the shape of the noise-reduction room 302 can be adjusted by the filling manner of the sound-absorption member 5 therein in compliance with the desired configuration of the casing unit 3.
  • the base 312 includes a bottom plate 316 that is distal to the cover 311 and that is formed with an outer tube-communicating through hole 317.
  • the air-entering tube 33 peripherally and outwardly extends from and is in spatial communication with the outer tube-communicating through hole 317.
  • a fourth embodiment of the fan device according to the disclosure is illustrated.
  • the fourth embodiment is structurally similar to that of the first embodiment.
  • the casing body 31 of the casing unit 3 is formed with an outer tube-communicating through hole 317' in spatial communication with the receiving space 310.
  • the outer tube-communicating through hole 317' and the porous plate 32 are located at two opposite sides of the fan impeller unit 4 along the axis (A), such that the noise-reduction room 302 is distal to the air-entering tube 33.
  • the air-entering tube 33 peripherally and outwardly extends from and is in spatial communication with the outer tube-communicating through hole 317'.
  • the airflow generated by the fan impeller unit 4 partially flows from the air-flowing room 301 into the noise-reduction room 302 through the porous plate 32, and the airflow is simultaneously dispersed by the porous plate 32 to reduce wind shear. Therefore, the noise generated by the fan impeller unit 4 of the fan device according to the disclosure can be reduced.
