As shown in the drawings, the oil-gas separation assembly of the present application includes a fixed scroll 1 and a head cover 2. The top cover 2 is arranged on the fixed scroll 1 through bolts, a cavity 3 is formed between the fixed scroll 1 and the top cover 2, and a first baffle 31, a second baffle 32 and a third baffle 33 are arranged in the cavity 3. The first baffle 31, the second baffle 32 and the third baffle 33 form an oil gas passage 34. The fixed scroll 1 has an oil return passage 11, the head cover 2 has an exhaust port 21, and the oil-air passage 34 communicates the oil return passage 11 and the exhaust port 21, respectively.
In particular, the oil and gas passage 34 includes a first passage 341, a second passage 342, a third passage 343, and a fourth passage 344. The first baffle 31 forms a first passage 341 with a sidewall of the head cover 2, and the first baffle 31 surrounds the discharge valve 13 of the fixed scroll 1. The second baffle 32 surrounds the first baffle 31, the second baffle 32 and the side wall of the top cover 2 form a second channel 342, and the second channel 342 is communicated with the first channel 341. The third baffle, the second baffle 32 and the side wall of the top cover 2 form a third channel 343, and the third channel 343 is respectively communicated with the second channel 342 and the exhaust port 21 of the top cover 2. The first baffle 31, the third baffle 33 and the side wall of the top cover 2 form a fourth channel 344, and the fourth channel 344 is respectively communicated with the second channel 342 and the oil return channel 11.
Preferably, one side surface of the third baffle 33 faces one end of the second baffle 32, and an extension line of the second baffle 32 makes an angle α with an extension line of the third baffle 33. When the refrigerant flows from the second channel 342 to the third baffle 33, the refrigerant directly impacts the third baffle 33, the gas in the refrigerant reversely flows under the blocking action of the third baffle 33 and is discharged through the third channel 343 and the exhaust port 21 in sequence, and the refrigeration oil in the refrigerant adheres to the third baffle 33, so that the oil and gas are separated, and the separated refrigeration oil sequentially flows through the fourth channel 344 and the oil return channel 11 under the action of self gravity and returns to the oil pool of the compressor shell for recycling.
Preferably, alpha is more than or equal to 45 degrees and less than or equal to 135 degrees, thus being beneficial to improving the oil-gas separation effect.
Preferably, the third baffle 33 is inclined at an angle β, specifically, an acute angle β, to the oil storage chamber 12 of the fixed scroll 1, so that the refrigerant oil separated from the refrigerant flows into the oil storage chamber 12 by gravity, and then flows through the fourth passage 344 and the oil return passage 11 in sequence to return to the oil sump of the compressor housing.
Preferably, the volume of the oil storage chamber 12 is more than one third of the oil filling amount of the scroll compressor, so as to ensure good oil-gas separation effect of the scroll compressor.
