Embodiment
As shown in Figure 1 and Figure 2, the present embodiment provides a kind of refrigeration compressor muffler, the second housing 2 overlap joint first
First housing 1 and the second housing 2 are separated into two independent sealed chambers by housing 1, dividing plate 3, are first independent close in the first housing 1
Chamber 6 is sealed, is the second independent sealed chamber 7 in the second housing 2.The first independent sealed independent sealed arranged in series of chamber 7 of chamber 6 and second,
Noise reduction frequency range is widened, improves erasure effect.Inner connecting tube 4 sequentially passes through the first housing 1, the housing 2 of dividing plate 3 and second, inner connecting tube 4
Cross-sectional area is respectively less than the first housing 1, the cross-sectional area of the second housing 2, and inner connecting tube 4 is in the first housing 1, the second housing 2
Part offers several through holes 5.The ratio and second of the cross-sectional area of first housing 1 and the cross-sectional area of inner connecting tube 4
The ratio of the cross-sectional area of housing 2 and the cross-sectional area of inner connecting tube 4 is referred to as divergence ratio, and divergence ratio is bigger, the sound-damping qualities of muffler
It is bigger.The second independent sealed chamber 7 in the first independent sealed housing 2 of chamber 6 and second in first housing 1 is cylindrical cavity
