Afterbody is provided with dividing plate two, and top is provided with cylindrical dilatation hole one；The U-tube front lower portion is provided with dividing plate three, middle part
Dividing plate four is provided with, rear portion is provided with penetrating rectangle expanded bore two；Dividing plate one, the dividing plate two of the coiled pipe are respectively engaged with
On the neck one and neck two of lower cavity wall, in lower intracavitary formation resonant cavity one, the dividing plate four of the U-tube is connected to lower intracavitary
On the neck three of wall, in lower intracavitary formation resonant cavity two；Between raised dividing plate in the middle of the U-tube dividing plate three and cavity of resorption bottom
Through hole is formed, the through hole both sides are in lower intracavitary formation resonant cavity three and resonant cavity four.
The internal diameter of the coiled pipe is 7mm.
The internal diameter of the U-tube is 8mm.
The aperture in the cylindrical dilatation hole one is 7mm.
A length of 6mm of the rectangle expanded bore two, a width of 5mm.
The equivalent diameter of the through hole is 6mm.
The quantity of the oil leaking hole is 4, a diameter of 1.5mm.
The utility model can simplify mould, be conducive to the demoulding of mould by simplifying muffler cavity of resorption and bend pipe, so that
The cost of injection is reduced, after being verified by using analog simulation and experiment to this muffler, it is found that the noise of compressor can
With average reduction 3.27dB.Because the muffler is reasonable in design, simple in construction, easy to use, thus it is empty with wide market
Between.

Embodiment
As Figure 1-4, it is a kind of to reduce the muffler of freezer compressor noise, including epicoele 1, cavity of resorption 2, by half-and-half two
The coiled pipe 3 of part merging, the U-tube 4 merged by double of two parts, the epicoele 1 are welded on down by iron wire
The top of chamber 2, the coiled pipe 3 is connected to the right side that the left side inside cavity of resorption 2, U-tube 4 are connected to inside cavity of resorption 2, the cavity of resorption
The raised dividing plate 8 for being molded with that height is 4mm in the middle of neck 1, neck 26, neck 37, bottom, bottom plate are molded with 2 inwalls
On be molded with 4, a diameter of 1.5mm oil leaking hole 9；The front end of coiled pipe 3 is molded with dividing plate 1, afterbody and is molded with dividing plate
2 11, top is molded with the cylindrical dilatation hole 1 that aperture is 7mm；The front lower portion of U-tube 4 is molded with length for 23mm
Dividing plate 3 19, middle part is molded with dividing plate 4 13, and rear portion is molded with penetrating a length of 6mm, a width of 5mm rectangle expanded bore two
14；Dividing plate 1, the dividing plate 2 11 of the coiled pipe 3 are respectively engaged with the neck 1 and neck 26 of the inwall of cavity of resorption 2, under
Resonant cavity 1 is formed in chamber 2, the dividing plate 1 is relative with the air entry of cavity of resorption 2 to be connect；The clamping of dividing plate 4 13 of the U-tube 4
On the neck 37 of the inwall of cavity of resorption 2, resonant cavity 2 15 is formed in cavity of resorption 2；In the U-tube dividing plate 3 19 and the bottom of cavity of resorption 2
Between raised dividing plate 8 between be formed with the through hole 18 that equivalent diameter is 6mm, the both sides of through hole 18 form resonance in the cavity of resorption 2
Chamber 3 16 and resonant cavity 4 17, the mouth of pipe at the top of dividing plate 3 19 is relative with the exhaust outlet of epicoele 1 to be connect.
Operation principle of the present utility model is：Sound is entered by the exhaust outlet of epicoele 1, is delivered to the U-tube that internal diameter is 8mm
In 4, when sound passes through resonant cavity 2 15, under the expansion sound deadening of rectangle expanded bore 2 14, the energy of sound reduces one
Part, sound continues to be delivered in resonant cavity 4 17, and sound is expanded in bigger cavity from the pipeline that internal diameter is 8mm, sound
The energy of sound reduces a part again, and the rest may be inferred, when sound is reached in resonant cavity 3 16 by through hole 18, then from resonant cavity three
Shunk in 16 and pass through cylindrical reaming one 12 of the internal diameter for 7mm coiled pipe 3 and 7mm into resonant cavity 1, most afterwards through cavity of resorption 2
Air entry be delivered in compressor.Sound shrinks by four constantly expansions, the substantial amounts of loss of energy so that sound is significantly
Reduction, so as to reach the effect of noise reduction.
It is described above, only the utility model preferably embodiment, but the utility model protection domain not office
It is limited to this, for example, equivalent substitution or change is subject to according to the technical solution of the utility model and its inventive concept, should all covers
Within protection domain of the present utility model.
