Embodiment 1

[0064] like Figure 1 to Figure 10 As shown, the embodiment of the first aspect of the present invention proposes a muffler 100 comprising a first housing 110 and a second housing 120, that is, the muffler 100 comprises two independent housings, when the first housing 110 When assembling with the second housing 120 , the respective structures of the first housing 110 and the second housing 120 are used to cooperate to achieve the purpose of enclosing a muffler cavity 130 .

[0065] The first housing 110 is provided with an air inlet 112 , and the second housing 120 is provided with an air outlet 122 , and both the air inlet 112 and the air outlet 122 communicate with the muffler cavity 130 . In this way, the gaseous refrigerant enters the muffler 100 through the air inlet 112 , flows through the muffler cavity 130 and then flows out of the muffler 100 through the gas outlet 122 . Since the size of the air inlet 112 and the air outlet 122 is smaller than the size of the muffle...

Embodiment 2

[0071] According to an embodiment of the present invention, it includes the features defined in any of the above embodiments, and further: the inner surface of the first housing 110 is recessed to form a part of the sound-absorbing cavity 130, and the inner surface of the second housing 120 is recessed to form Another part of the muffler cavity 130 . That is, the structural features of the first housing 110 and the second housing 120 are used to enclose an independent muffler chamber 130, so that the refrigerant suffers less resistance in the muffler chamber 130 during the suction process of the compressor, and the refrigerant flows It is smoother, while ensuring the noise reduction performance, it greatly reduces the pressure loss of the refrigerant flow, which is conducive to improving the cooling efficiency. This setting reduces the component parts of the muffler 100 and simplifies the assembly process of the muffler 100 , thereby improving the assembly efficiency of the pr...

Embodiment 3

[0073] like figure 1 , figure 2 , Figure 7 , Figure 8 and Figure 10As shown, according to an embodiment of the present invention, it includes the features defined in any of the above embodiments, and further: the muffler 100 also includes a first fitting part 140 and a second fitting part 150, a first housing 110 and a second fitting part One of the housings 120 is provided with a first matching portion 140 , and the other housing is provided with a second matching portion 150 , by setting the first matching portion 140 and the second matching portion 150 . When the first housing 110 and the second housing 120 are assembled, at least part of the first matching portion 140 is accommodated in the second matching portion 150 to connect the first housing 110 and the second housing 120 together. That is to say, at least a part of the first fitting part 140 is inserted into the second fitting part 150, this setting can ensure the airtightness of the fitting place of the firs...

Abstract

The invention provides a silencer, a compressor and refrigeration equipment. The silencer comprises a first shell and a second shell; and the first shell is provided with an air inlet; and the second shell is provided with an air outlet, a silencing cavity is defined by the first shell and the second shell, and the air inlet and the air outlet both communicate with the silencing cavity. The silencer is of a single-silencing-cavity structure, resistance borne by a refrigerant in the silencing cavity in the air suction process of the compressor is smaller, flowing of the refrigerant is smoother, the silencing performance is guaranteed, meanwhile, pressure loss of flowing of the refrigerant is greatly reduced, the refrigeration efficiency can be improved, and in other words, the refrigeration performance is optimized while the silencing performance of the silencer is guaranteed, and the effect of considering the working efficiency and the noise elimination effect of a product is achieved. And the silencing cavity is defined by the first shell and the second shell, so that the silencer has the advantages of few parts and easiness in processing and assembling, and the production cost of a product is reduced.
