Referring to fig. 4, the oil separator further includes a flow distribution plate 4, the flow distribution plate 4 includes a plurality of through hole portions 41 penetrating through upper and lower surfaces of the flow distribution plate 4, and a boss portion 42 protruding along a lower end of the through hole portions 41, the number of the through hole portions 41 is plural (8 through hole portions are provided in the drawing), the plurality of through hole portions 41 are distributed along a circumferential direction of the flow distribution plate 4, and the through hole portions 41 can be uniformly distributed on the flow distribution plate 4, so that the boss portion 42 can guide the gas-oil mixed refrigerant more uniformly.
The bottom of the flow distribution plate 4 is provided with 1/4 spherical plate-shaped boss portion 42, the 1/4 spherical plate-shaped boss portion 42 can be directly formed on the flow distribution plate 4 by punching to form a hollow 1/2 spherical plate-shaped protrusion, and then half of the protrusion is cut to obtain 1/4 spherical plate-shaped hollow boss portion 42, due to the arrangement of the boss portion 42, after the gas-oil mixed refrigerant flows to the flow distribution plate 4, the gas-oil mixed refrigerant can flow to the inner wall of the device body 1 under the guiding action of the boss portion 42, it is noted that the boss portion 42 can be integrally formed on the flow distribution plate 4 by metal punching or the like, or can be fixedly connected to the flow distribution plate 4 by welding or the like, and the flow guide portion 42 is not limited to 1/4 spherical plate-shaped structure, as long as the gas-oil mixed refrigerant can flow to the inner wall of the device body 1, for example, an, The arc-shaped panel-shaped structure, certainly, the 1/4 spherical panel-shaped boss part 42 is easy to process on one hand, and the 1/4 spherical panel-shaped boss part 42 has a spherical inner wall and has a good flow guiding effect; in addition, the 1/4 spherical external spherical surface can reduce the flow resistance as much as possible, and reduce the influence on the stable flow of the gas-oil mixed refrigerant.
The flow distribution plate 4 is fixedly connected or limited to the barrel 1, and referring to fig. 2 specifically, the shape of the flow distribution plate 1 is adapted to the shape of the barrel 12, in this embodiment, the barrel 12 is circular, the flow distribution plate 4 is also circular, and in addition, the outer diameter of the flow distribution plate 4 is larger than the inner diameter of the barrel 12, so that the upper end surface of the barrel 12 can support the flow distribution plate 4, and the flow distribution plate 4 does not fall off.
Referring to fig. 3 specifically, the first end cover portion 12 includes a connecting portion 111 and a pressing portion 112, the connecting portion 111 and the pressing portion 112 may be integrally formed, in the oil separator provided in this embodiment, the connecting portion 111 is sleeved on the outer surface of the cylindrical body portion 12 and is fixedly connected with the outer surface of the cylindrical body portion 12 in a welding manner, so that the first end cover portion 11 is fixedly connected with the cylindrical body portion 12, and the connecting portion 111 and the pressing portion 112 may be substantially vertically arranged or may be arranged at other angles.
The connecting portion 111 of the first end cover portion 11 is sleeved on the outer surface of the barrel portion 12 and fixedly connected to the outer surface of the barrel portion 12 in a welding manner, and then the lower surface of the abutting portion 112 contacts with the upper surface of the flow distribution plate 4, so that the flow distribution plate 4 abuts against the abutting portion 112, and in addition, the flow distribution plate 4 is supported on the upper end surface of the barrel portion 12, so that the flow distribution plate 4 is limited between the first end cover portion 11 and the barrel portion 12.
Besides, in a form that the flow distribution plate 4 is limited between the first end cover 11 and the barrel 12, the flow distribution plate 4 of the oil separator provided in this embodiment may also be fixedly connected to the first end cover 11 and the barrel 12, specifically, the flow distribution plate 4 may be fixedly connected to the barrel 12 in a welding manner, and at the same time, fixedly connected to the first end cover 11 in a welding manner, and may also be set as follows: the flow distribution plate 4 is fixedly connected to one of the cylinder 12 and the first end cover 11 by welding, and the flow distribution plate 4 abuts against the other of the cylinder 12 and the first end cover 11.
Because the abutting between the abutting portion 112 of the first end cover portion 11 and the dividing plate 4 is tight, and in addition, the contact surface between the abutting portion 112 and the dividing plate 4 can also basically meet the requirement of air tightness, no matter the form of direct abutting or welding is adopted between the first end cover portion 11 and the dividing plate 4, the requirement of air tightness can be met, so that the gas-oil mixed refrigerant entering the device body 1 from the inlet pipe 2 can not or rarely enter the lower part of the dividing plate 4 through the gap between the abutting portion 112 and the dividing plate 4 (not through the through hole portion 41 arranged on the dividing plate 4), and therefore, no matter the dividing plate 4 is fixedly connected or limited to the device body 1, the principle is feasible.
Generally, the axial projection area of the through hole portion 41 is larger than the axial projection area of the boss portion 42, at this time, a part of the gas-oil mixed refrigerant does not collide with the inner wall of the device body 1 by the guiding action of the boss portion 42 to generate a centrifugal flow, but directly passes through the through hole portion 41, at this time, the part of the gas-oil mixed refrigerant does not collide with the device body 1 by the guiding action of the boss portion 42 to generate a centrifugal flow, in order to avoid or reduce the occurrence of this situation to improve the oil separation effect, the pressing portion 112 of the embodiment is configured to abut against the flow dividing plate 4, besides the pressing portion 112, a part of the flow area of the through hole portion 41 is covered by the pressing portion 112, please refer to fig. 5 specifically, wherein S5 is an inner edge line of the pressing portion 112, at this time, the axial projection area of the pressing portion 112 covers the axial projection area of the through hole portion 41, the covered portion is located, with this arrangement, the flow area of the through hole 41 is reduced, and the flow area of the through hole 41 is reduced, so that the air-oil mixed refrigerant passing through the through hole 41 is more easily guided by the boss 42, and more easily collides with the inner wall of the body 1 to generate a centrifugal flow.
Through the above arrangement mode, after entering the device body 1 through the inlet pipe 2, the gas-oil mixed refrigerant can be diffused into the cavity between the first end cover part 11 and the flow distribution plate 4, and then the gas-oil mixed refrigerant can pass through the through hole part 41 arranged on the flow distribution plate 4, flows to the inner wall of the device body 1 under the flow guide effect of the boss part 42, and generates centrifugal flow after colliding with the inner wall of the device body 1, so that oil drops are separated from gaseous refrigerant more easily under the action of centrifugal force, oil drop carrying is reduced, and the oil separation effect can be relatively improved.
