The invention relates to a silencer and a vehicle-mounted air conditioner silencing system, in the using process, fluid is introduced into an input pipe, such as a refrigerant in a vehicle-mounted airconditioner. The introduced fluid flows into a first insertion pipe from the input pipe, and then flows into a silencing cavity through the first insertion pipe. Due to the fact that the first insertion pipe is located in the silencing cavity, the cross section between the first insertion pipe and the silencing cavity changes suddenly to cause acoustic impedance changes, and an expansion type silencing structure is formed. Then, the fluid flowing into the silencing cavity sequentially flows through all split cavities through flow guide holes in partition plates; and finally, the fluid flows into an output pipe from the last split cavity and flows out of the output pipe. Due to the fact that silencing holes are formed in the partition plates, the silencing holes and the split cavities in the two sides of the silencing holes form a resonance type sound absorption structure, and noise in the silencing cavity is further weakened. Meanwhile, the silencer has the advantages of being simplein structure, low in manufacturing cost, convenient to use and the like, and large-scale application and popularization of the silencer are facilitated.

    本发明涉及一种消声器及车载空调消声系统,在使用过程中,将流体通入输入管中,比如车载空调内的冷媒。通入的流体从输入管中流入第一插入管中;再经由第一插入管中流入消声腔内。由于第一插入管位于消声腔内,因此,第一插入管与消声腔之间的截面突变会引起声阻抗变化,构成扩张式消声结构。接着,流入消声腔内的流体通过分隔板上的导流孔,依次流经各个分体腔内;最后,流体从最后一个分体腔内流入输出管中,并由输出管流出。由于分隔板上设有消声孔,因此,该消声孔与其两侧的分体腔构成共振式吸声结构,使得消声腔内的噪声得到进一步削弱。同时,本消声器具有结构简单、制作成本低、使用方便等特点,便于该消声器大规模推广运用。
