摘要： In a high-speed, high-volume ventilation fan, a noise attenuating housing structure (10) includes a perforated inner casing (44) contained within a solid-walled outer casing (12). Filling the space between inner and outer casings is a porous, sound-absorbing material (48a, 48b). To prevent loss of downstream pressure, and therefore operational efficiency, due to leakages of air through the sound absorbing material from the downstream side at the fan blades (36) to the upstream side thereof, an annular anti-flow barrier (54, 58) is situated in the space between the inner and outer casings slightly downstream of the fan blades. The structure thus provides a high degree of noise attenuation without sacrificing operational efficiency.

摘要： Air distribution systems and more particularly an apparatus for extracting air from a main supply duct to a branch duct. In conventional air distribution systems in a building, the air is branced from the main air supply duct to the various branch ducts through openings in the wall of the main duct. In such configurations, the noise level at the entrance to the branch duct is substantially the same as the noise level in the main duct. To reduce the noise level, a silencer is typically used of quite large dimensional characteristics at the exist or inlet of the fan in the main supply duct which has the obvious disadvantage of being costly, bulky, and requiring a large amount of space. To obviate such noted problems, a composite branch take-off silencer device is set forth that includes a static pressure regain (SPR) section (100) and a channel section (101) adapted for coupling air flow from an input duct (102A) to an output duct (102B) and at least one branch duct (106, 108). The outer wall of the SPR section and the inner and outer path-defining walls of the channel section define a perimeter channel, with the outer walls having a composite cross section characterized by a continous curve, and the inner wall having a cross section characterized by a continuous curve, where both continuous curves have radial direction components.

摘要： Silencing equipment is provided for an air-cooling assembly in a large off-road vehicle having wheels, traction motors for the wheels that operate in a motoring mode to propel the vehicle and a power generating dynamic braking mode, resistor grids for dissipating the dynamic braking power, and a blower for moving cooling air past the grids to cool them. The silencing equipment may include a resistor grid housing (24) and at least one upper inlet (22) for passing cooling air to the interior of the housing. The inlet includes noise-absorbing material. A conduit (28) is provided for directing cooling air from the upper inlet through a transition chamber to reach the blower and at least one resistor grid in the housing. The conduit is lined with noiseabsorbing material. A removable cover (30) is provided in the conduit for accessing the air blower in the housing through the transition chamber, whereby servicing of the blower may be performed without removal of the entire upper inlet. In another aspect, the silencing equipment includes at least one outlet (31) for exhausting air from the resistor grid housing. This outlet includes a plurality of exhaust vanes positioned at an angle relative to a stream of exhaust air to impart a deflection to the exhaust air into a desired direction. The plurality of exhaust vanes includes noise-adsorbing material whereby this one outlet combines air deflection and silencing in a single device.

摘要： A compact air handling system includes an inlet channel which defines an inlet flow path in a first direction along a flow axis and a discharge channel which defines a discharge flow path in a second direction, opposite to the first direction along the flow axis. Air enters the air handling system through an inlet port and is discharged via a discharge port. The inlet channel is provided with acoustical buffering to attenuate inlet noise. The discharge channel is also provided with acoustical buffering in the form of a discharge silencer to attenuate noise in the discharge channel. The discharge silencer is disposed between the inlet channel and the discharge channel. An acoustical inlet plenum couples the inlet channel to the discharge channel. The cross-sectional area of the discharge channel adjacent the discharge port is larger than the cross-sectional area of the discharge channel adjacent the acoustical inlet plenum. If the inlet ports are not substantially equally distributed about the air handling system a transfer passage can be provided between the inlet ports and the inlet channel to provide equalization of the air flow.
