In addition, can also between air-breathing end cap inner wall 1 and suction end cover outer wall 2 stuffed heat insulated device, to further prevent
In the heat transfer to suction end cover outer wall 2 of air-breathing end cap inner wall 1, and suction end cover outer wall 2 is made the appearance of the problem of condensation occur.
It can be thermal insulation board for heat-proof device, as long as being able to achieve heat-insulated device in protection scope.
In one embodiment, the gap between air-breathing end cap inner wall 1 and suction end cover outer wall 2 can be with compressor
Refrigerant flow path is connected to the import of compressor compresses chamber.Settable refrigerant flow path in gap disclosed herein, with
It is connected to the refrigerant flow path inside compressor, refrigerant enters the refrigerant flow path in gap to motor after cooling, to system
Cryogen is integrated, and then enters compression chamber by the compression chamber import of compressor again.Above-mentioned set-up mode can not only be to system
The flow path of cryogen is integrated, and can improve Flow Field Distribution reduces flow resistance, and the also absorbable thermal energy of the refrigerant in gap,
Alleviate the dew condensation phenomenon of suction end cover outer wall 2, also absorbable noise reduces entire compressor and passes to extraneous noise pollution.
In addition, the refrigerant in refrigerant flow path inside compressor can also directly pass through compressor after cooling to motor
The import of compression chamber, which enters in compression chamber, to be compressed.
In further embodiment, outer wall 2 is fixedly mounted on inner wall 1, and inner wall 1 have can be connected to shape with gap
At the notch of vibration damping chamber 4.Specifically, the gap between the outer wall 2 and inner wall 1 is connected to the notch of inner wall 1, i.e., so that gap with
Inner cavity connection.When the section of the inner wall 1 of air-breathing end cap mutates, the damping chamber 4 with damping and silencing effect will form, from
And achieve the purpose that damping and silencing.For variable section shape at vibration damping chamber 4 shock absorption principle and Helmholtz resonator importing
The variable cross-section of access is identical.And the size of outer wall 2 can be set according to different, and in protection scope.
Specifically, outer wall 2 is the circumferential direction that inner wall 1 is arranged in, and the bulge loop of outwardly convex.Since the vibration damping chamber 4 is air-breathing
The circumferential cross-section of end cap outer wall 2, which is mutated, to be formed, therefore, when bulge loop to the direction protrusion far from air-breathing end cap inner wall 1, vibration damping
Chamber 4 is connected to gap.In practice, it is circumferential to close to air-breathing end cap inner wall vibration damping chamber 4 can also to be set to suction end cover outer wall 2
The bulge loop of 1 direction protrusion.The size of vibration damping chamber 4 can be set according to different, and in protection scope.
It is in further embodiment that suction end cover outer wall air inlet 21 and air-breathing end cap inner wall air inlet 11 is not opposite
Arrangement, and the air inlet of the two is connected to by gap, and the filter 3 of compressor is mounted on air-breathing end cap inner wall air inlet 11,
In addition, the filter 3 of the compressor is also mountable in suction end cover outer wall air inlet 21.By by suction end cover outer wall air inlet
21 are staggeredly arranged with air-breathing end cap inner wall air inlet 11, and the gas direction entered is made to change, and with the flow velocity of mitigation of gases, increase
The heat exchange efficiency of the gas in gas and compressor in wide arc gap.In addition, suction end cover outer wall air inlet 21 and air-breathing end cap
Gap between inner wall air inlet 11 can form vibration damping chamber 4, achieve the purpose that damping noise reduction.For suction end cover outer wall air inlet
21 and the position of air-breathing end cap inner wall air inlet 11 can be changed according to the frequency of noise to be eliminated, and in protection scope.
In preferred embodiment, by the axis of the axis of suction end cover outer wall air inlet 21 and air-breathing end cap inner wall air inlet 11
Line is arranged vertically, i.e., the direction of two air inlets is vertical.In direction and air-breathing end cap for suction end cover outer wall air inlet 21
The direction of wall air inlet 11 according to different can set, and in protection scope.
Disclosed herein as well is a kind of compressors, including air-breathing end cap, wherein air-breathing end cap is as public in above-described embodiment
