Embodiment
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
The special baffler of a kind of refrigeration system, comprises suction port and air outlet that baffler cylindrical shell and this two ends, baffler cylindrical shell left and right arrange respectively; As depicted in figs. 1 and 2, baffler cylindrical shell is made up of the right end socket 203 of the left end socket of baffler 201 of housing 202 with housing two ends, in baffler cylindrical shell, the first baffler dividing plate 301, second baffler dividing plate 302 is installed from suction port to air outlet successively, first baffler dividing plate 301 is provided with first-class circulation passage 401, the second baffler dividing plate 302 is provided with second circulation passage 402.
Inner barrel is divided into three cavitys i.e. the first baffler dividing plate 301, forms the first cavity 501 between left side end socket 201 and housing 202 by two the baffler dividing plates arranged in described baffler cylindrical shell; The second cavity 502 is formed between first baffler dividing plate 301, second baffler dividing plate 302 and housing 202; Second baffler dividing plate 302, between right side end socket 203 and housing formed the 3rd cavity 503.These three cavitys are the silencing cavity of this baffler.
Each baffler dividing plate is equipped with circulation passage; Suction port is provided with suction tude 101, air outlet is provided with steam outlet pipe 102.Refrigerant gas enters the first cavity 501 of baffler by suction tude 101, by the sudden change of actual internal area, cause sound wave reflection, projection acoustic energy is reduced, the second cavity 502 is entered by first-class circulation passage 401 after reducing acoustic energy, after reflection noise abatement, enter the 3rd cavity 503 by second circulation passage 402, finally by refrigeration agent steam outlet pipe 102 exhaust silencer.
Reduce resistance for ease of refrigeration agent circulation, in the adapter of flow of refrigerant warp, the two ends of circulation passage all arrange groove, and groove angle is preferably 45 °, to reduce energy loss.
For avoiding refrigeration oil to deposit in the filter, be all provided with a breach in the bottom of described baffler dividing plate.And breach surrounding chamfer polishing.Breach can be generally triangle, rectangle or circle.In order to ensure the structural strength of dividing plate, generally breach is made triangle.Respective figure, namely respectively offers a breach 601 at the first baffler dividing plate 301 and the second baffler dividing plate 302 bottom, and does 45 ° of chamfer polishing process.When the horizontal installation of baffler, this breach is arranged on bottom, is beneficial to refrigeration oil flowing, increase the probability that compressor taken back by refrigeration oil by refrigerant air-flow.
It should be noted that, one end that described steam outlet pipe is connected with described air outlet is stretched in baffler cylindrical shell cavity.Near the circulation passage of described suction port, to be symmetrically arranged on the baffler dividing plate at its place.And the circulation passage near described air outlet, be arranged on the side away from described air outlet on the baffler dividing plate corresponding to it.Better can reach the effect of turbulent noise reduction.Certainly, the center-biased that the center of circulation passage is equivalent to described baffler cylindrical shell arranges and can realize better turbulent effect.
It should be noted that, suction tude 101 and steam outlet pipe 102 preferably can adjustablely be arranged on baffler cylindrical shell, concrete, namely by the distance between suction tude 101 and first-class circulation passage 401, and the distance between second circulation passage 402 and steam outlet pipe 102 can regulate, and can reduce the acoustic energy of different frequency noise.
Or, according to different demands, by the distance between suction tude 101 and first-class circulation passage 401, and the distance adjustment between second circulation passage 402 and steam outlet pipe 102 becomes incoordinate size, like this, just change baffler cavity glottis neoplasms, thus reduce the natural frequency of baffler, make the baffler of equal length and diameter in original design can obtain lower noise reduction frequency, the noise of same characteristic frequency can be eliminated.
The utility model sound-deadening and noise-reducing Be very effective, acoustic energy enters in baffler cylindrical shell by suction port, entered three cavitys that inner barrel is separated by two baffler dividing plates, overwhelming majority acoustic energy is all converted into potential energy, and produce turbulent flow, acoustic energy along pipe transmmision then partly turns back, and effectively can reduce noise like this, avoid the hydrodynamic noise of refrigeration agent in refrigerant line.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
