The ratio of the distance between the lowest end of the second refrigerant outlet 140 and the highest end of the first refrigerant outlet 130 to the inner diameter of the second refrigerant outlet 140 is greater than or equal toAnd the ratio is less than or equal to +.>In this way, when the liquid refrigerant in the accommodating cavity 110 is more, the liquid refrigerant exceeds the lowest end of the second refrigerant outlet 140 to flow out from the second refrigerant outlet 140, and the flow path of the gaseous refrigerant can be reduced, so that the gaseous refrigerant can flow out from the second refrigerant outlet 140 in time after being separated, and the gas-liquid separation effect is improved.
In some alternative embodiments, the ratio between the distance between the lowest end of the second refrigerant outlet 140 and the highest end of the first refrigerant outlet 130 and the inner diameter of the second refrigerant outlet 140 may be Or->Etc.
Illustratively, as shown in fig. 1-3, the second refrigerant outlet 140 is provided in a circumferential sidewall of the liquid separation tube segment 100.

Further, as shown in fig. 1 to 3, the refrigerant inlet 120 is provided on the circumferential side wall of the liquid separation pipe section 100.
Further, in the case where the second refrigerant outlet 140 and the refrigerant inlet 120 are both disposed on the circumferential side wall of the liquid separation pipe section 100, the connecting line between the second refrigerant outlet 140 and the center of the liquid separation pipe section 100 is a first line segment, the connecting line between the refrigerant inlet 120 and the center of the liquid separation pipe section 100 is a second line segment, and the angle range of the angle between the first line segment and the second line segment is 0 to 90 degrees.
In this embodiment, the refrigerant inlet 120 is disposed on the circumferential side wall of the liquid separation tube segment 100, and after the two-phase refrigerant enters the accommodating cavity 110 through the refrigerant inlet 120, the two-phase refrigerant can collide with the circumferential side wall of the liquid separation tube segment 100 on the opposite side of the refrigerant inlet 120 due to the flowing action of the two-phase refrigerant. In this embodiment, along the radial direction of the liquid separation tube segment 100, the line connecting the second refrigerant outlet 140 and the center of the liquid separation tube segment 100 is a first line segment, the line connecting the refrigerant inlet 120 and the center of the liquid separation tube segment 100 is a second line segment, and the angle of the break angle between the first line segment and the second line segment is 0 to 90 degrees. As shown in fig. 2 and 3, in this way, the second refrigerant outlet 140 may be disposed on the same side of the refrigerant inlet 120 along the radial direction of the liquid separation tube segment 100, so that the second refrigerant outlet 140 may be reduced from being disposed on the circumferential side wall of the liquid separation tube segment 100 opposite to the refrigerant inlet 120, resulting in that two-phase refrigerant may directly flow out of the accommodating cavity 110 through the second refrigerant outlet 140, and the gas-liquid separation effect is poor, thereby improving the gas-liquid separation effect of the gas-liquid separation device.
In some alternative embodiments, as shown in fig. 1 to 3, the liquid separation tube segment 100 is further provided with a third refrigerant outlet 150, where the third refrigerant outlet 150 is disposed at a position higher than the refrigerant inlet 120, and the third refrigerant outlet 150 is used for flowing out the gaseous refrigerant.

At this time, the two-phase refrigerant can be buffered, and the gaseous refrigerant flows upward and the liquid refrigerant flows downward due to self gravity. In this way, the rising gaseous refrigerant can flow out of the accommodating chamber 110 through the third refrigerant outlet 150 to enhance the gas-liquid separation effect.
Further, as shown in fig. 1 to 3, the second refrigerant outlet 140 is disposed at a position lower than the refrigerant inlet 120.

In this embodiment, the third refrigerant outlet 150 is provided at the top wall of the liquid separation tube segment 100, so that the gaseous refrigerant separated after collision can directly flow out of the accommodating cavity 110 through the third refrigerant outlet 150.
In another embodiment, the third refrigerant outlet 150 is provided in a circumferential sidewall of the liquid separation tube segment 100.
Further, in the case where the third refrigerant outlet 150 and the refrigerant inlet 120 are both disposed on the circumferential side wall of the liquid separation pipe section 100, the line connecting the third refrigerant outlet 150 and the center of the liquid separation pipe section 100 is a third line segment, the line connecting the refrigerant inlet 120 and the center of the liquid separation pipe section 100 is a second line segment, and the angle of the break angle between the third line segment and the second line segment is 0 to 90 degrees along the radial direction of the liquid separation pipe section 100.

In this embodiment, along the radial direction of the liquid separation tube segment 100, the line connecting the third refrigerant outlet 150 and the center of the liquid separation tube segment 100 is a third line segment, the line connecting the refrigerant inlet 120 and the center of the liquid separation tube segment 100 is a second line segment, and the angle between the third line segment and the second line segment ranges from 0 degrees to 90 degrees. In this way, along the radial direction of the liquid separation tube 100, the third refrigerant outlet 150 can be disposed on the same side of the refrigerant inlet 120, so that the third refrigerant outlet 150 can be reduced from being disposed on the circumferential side wall of the liquid separation tube 100 opposite to the refrigerant inlet 120, which results in that two-phase refrigerant can directly flow out of the accommodating cavity 110 through the third refrigerant outlet 150, the gas-liquid separation effect is poor, and the gas-liquid separation effect of the gas-liquid separation device is improved.
