Wind passage housing is fixed, and the circular arc profiled orifice plate is arranged between resonance cavity shell and air intake passage housing.
Further preferred structure, the circular arc profiled orifice plate are the arc-shaped platy structure of section, the circular arc profiled orifice plate
Cylindrical air intake passage is surrounded between inside and air intake passage housing, resonant cavity is surrounded between outside and resonance cavity shell, it is described
Several circular holes are opened up on circular arc profiled orifice plate.Air intake passage original structure is not changed, windage is small.
Further preferred structure, it is described resonance cavity shell include outside plate and with outside plate side plate connected vertically, the side
Plate outer is the arcuate structure to match with circular arc profiled orifice plate section arc.
Further preferred structure, on the outside of the circular arc profiled orifice plate, resonant cavity case inside be respectively equipped with two it is corresponding
Cross-rib, by resonant cavity separation be split into four different size of chambers.
Further preferred structure, the resonance cavity shell outer be equipped with for the fixed lifting lug of air intake passage housing.
Further preferred structure, the air intake passage housing one side set hatch frame, the hatch frame end face be with
Resonate the fixed sealing surface of cavity shell.
Further preferred structure, the circular arc profiled orifice plate are equipped with to avoid the escape groove of peripheral component.
Further preferred structure, a diameter of 3-10mm of the circular hole.
The present invention is not in the case where changing the performances such as former air-conditioning assembly overall dimension and air quantity, only by air-conditioning
Resonant cavity is set on assembly inlet channel, can effectively reduce air-conditioning assembly overall noise, the noise that can be also directed to air-conditioning assembly is special
Property, by changing the size of resonant cavity, realize the peak noise for reducing low and medium frequency section, promote timbre matter.
