Existing automotive air-conditioning system is due to lightweight, integrated requirement, therefore it is small to be limited to arrangement space, and sound poor quality is mainly asks Topic.Since surrounding enviroment part has been cured, the improvement of noise can only carry out under existing boundaries.
The content of the invention
The defects of purpose of the present invention is aiming at the prior art provides a kind of air-conditioning assembly resonant cavity denoising structure.
The technical solution adopted by the present invention is:Including air intake passage housing, along air inlet side in the air intake passage housing To passage be equipped with resonant cavity, the resonant cavity is surrounded by the circular arc profiled orifice plate cavity shell that shakes together, the resonance cavity shell with into 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.
