Abstract

PURPOSE: An oil separator is provided to optimize by simplifying a structure, to improve the performance of separating oil and to simply perform an assembling process. CONSTITUTION: Oil particles combined into a bubble type by a separating net(13) are firstly splashed by flowing upon flowing in an oil separation chamber(8) and secondly separated from mixed gas and a centrifugal force by a baffle(11) upon U-turn. The separated oil is collected at a lower part of the oil separation chamber and flowed to an absorption side of a compressor through an oil discharge hole(10a). Herein, fine particles generated by the corrosion of a cooling line and mechanic friction are flowed in the collected oil at the lower floor of the oil separation chamber while circulating with a coolant. In addition, the impurities are not flowed in the compressor by being filtered by a filter(12) combined on an end of the oil discharge hole.

Description

오일분리기Oil separator

본 발명은 차량 공조장치에 이용되는 냉각시스템에 있어서, 압축기에서 토출되는 냉매.오일혼합기체로부터 오일과 냉매를 분리하고 분리된 오일을 압축기로 환원하는 오일분리기에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil separator for separating oil and refrigerant from a refrigerant and an oil mixture gas discharged from a compressor and reducing the separated oil to a compressor in a cooling system used in a vehicle air conditioner.

일반적으로 압축기는 냉매가스에 미스트형으로 분산된 오일에 의해 압축운전중에 있는 압축기내의 습동부의 윤활을 도모하고 있다.Generally, the compressor seeks to lubricate the sliding parts in the compressor during the compression operation by oil dispersed in the mist type in the refrigerant gas.

그러나 오일이 압축기의 기계적인 마찰로 인해 필수적이기는 하나 열교환기측으로 흐를 경우 냉매와 혼합된 오일이 냉매의 열용량을 흡수하므로 고압측의 온도를 하강시키고 반대로 저압측에서는 온도를 높이는 등 열교환기의 열교환 효율을 떨어뜨리게 된다. 또한 열교환기를 흐르는 오일이 열교환기의 전열표면에 대류함으로써 냉매의 유동분배가 균일하지 못해 압력강하가 커지게 된다.However, although oil is essential due to mechanical friction of the compressor, when the oil flows to the heat exchanger side, the oil mixed with the refrigerant absorbs the heat capacity of the refrigerant. Therefore, the heat exchange efficiency of the heat exchanger is increased by lowering the temperature at the high pressure side and increasing the temperature at the low pressure side. Dropped. In addition, since the oil flowing through the heat exchanger convections to the heat transfer surface of the heat exchanger, the flow distribution of the refrigerant is not uniform, resulting in a large pressure drop.

이런점을 감안하여 압축 운전중에 토출냉매가스에 포함된 오일을 오일분리기에서 분리하여 저유실에 저장하도록 하고 있다. 오일분리기는 압축기에 일체로 형성된 내장형과 압축기의 토출측과 응축기사이에 개재되는 분리형이 있다.In view of this, the oil contained in the discharged refrigerant gas during the compression operation is separated from the oil separator and stored in the oil storage chamber. The oil separator has a built-in type integrally formed in the compressor and a separate type interposed between the discharge side of the compressor and the condenser.

종래의 분리형 오일분리기의 일예로 일본국 특개형 9-187617호는 압축기와 응축기 사이의 고압측 냉매.오일 혼합기체로부터 오일을 분리하는 오일분리기를 예시하고 있다. 2중 원통형 구조로서 비교적 복잡하고 제작하기에 어려우며 오일분리기의 크기가 커서 좁은 공간에 장착하기에 어려운 단점이 있다.As an example of a conventional oil separator, Japanese Patent Laid-Open No. 9-187617 illustrates an oil separator for separating oil from a high-pressure side refrigerant / oil mixture gas between a compressor and a condenser. As a double cylindrical structure, it is relatively complicated and difficult to manufacture, and the size of the oil separator is large, making it difficult to mount in a narrow space.

다른 예의 오일분리기는 오일분리 효율이 비교적 우수한데 반해 체적이 커지며 조립공수가 많은 단점이 있다.The oil separator of another example has the disadvantage that the oil separation efficiency is relatively good while the volume is large and the assembly labor is many.

본 발명의 목적은 구조를 단순화하여 최적화시키고 오일분리 성능을 향상시키며 조립공정을 간편히 행할 수 있는 오일분리기를 제공하는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide an oil separator that can simplify and optimize the structure, improve oil separation performance, and simplify the assembly process.

상기 목적을 달성하기 위한 본 발명은 상.하부가 개구되고 외주면 상부에 입구공 및 출구공이 서로 대향하여 형성된 관체형상의 오일분리실을 갖는 본체; 상기 본체의 상부 개구부를 밀폐하는 상캡; 상기 본체의 하부 개구부를 밀폐하며 중앙에 두께방향으로 오일배출구가 관통된 하캡; 상기 상캡의 저면 중앙으로부터 오일분리실 내부 하방으로 소정길이 돌설되며 폭방향 양측면이 상기 오일분리실 내주면과 접면되어 상기 입구공을 통해 유입된 냉매.오일 혼합기체가 Ｕ자 형태의 유동경로를 갖도록 하는 배플; 및 상기 오일분리실에 형성된 입구공과 배플사이에 나선형상으로 권면되어 냉매.오일 혼합기체로부터 오일을 분리하는 분리망;을 포함하는 것을 특징으로 한다.The present invention for achieving the above object is a main body having a tubular oil separation chamber formed in the upper and lower openings and the inlet and outlet holes on the outer circumferential surface facing each other; An upper cap for sealing an upper opening of the main body; A lower cap sealing the lower opening of the main body and having an oil outlet through the thickness in the center thereof; A predetermined length protrudes downward from the center of the bottom surface of the upper cap to the inside of the oil separation chamber, and both sides of the width direction are in contact with the inner circumferential surface of the oil separation chamber so that the refrigerant and oil mixed gas introduced through the inlet hole have a U-shaped flow path. baffler; And a separation net that is spirally wound between the inlet hole and the baffle formed in the oil separation chamber to separate the oil from the refrigerant and the oil mixture gas.

이러한 구성에 의하면, 압축기에서 유입된 냉매.오일혼합기체는 분리망에 의해 1차로 오일이 분리되며, 배플에 의해 Ｕ턴하면서 그 원심력에 의해 2차로 오일을 분리하게 된다. 냉매.오일 혼합기체로부터 분리된 오일은 자중에 의해 오일분리실 하부로 낙하되어 오일배출구를 통해 증발기로부터 유입된 액냉매와 혼합되어 압축기의 흡입측으로 환원된다.According to this configuration, the refrigerant and oil mixture gas introduced from the compressor are separated by the primary oil by the separation network, and are separated by the centrifugal force while being turned by the baffle. The oil separated from the refrigerant / oil mixture gas is dropped into the lower part of the oil separation chamber by its own weight, mixed with the liquid refrigerant introduced from the evaporator through the oil outlet, and reduced to the suction side of the compressor.

이하, 본 발명의 바람직한 실시예를 첨부된 도면을 통해 설명한다. 도 1은 본 발명의 실시예에 대한 오일분리기가 설치된 냉각싸이클을 보인 것으로, 압축기(1)의 토출측과 흡입측 사이에 외장형 오일분리기(2)를 설치하여 냉매와 함께 유동하는 압축기 윤활오일을 냉매.오일 혼합기체로부터 분리하여 압축기(1)로 다시 환원시키도록 한다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. 1 shows a cooling cycle in which an oil separator is installed according to an embodiment of the present invention, wherein an external oil separator 2 is installed between a discharge side and a suction side of a compressor 1 to cool a compressor lubricating oil flowing with the refrigerant. Separate from oil mixture gas and return to compressor (1).

오일분리기(2)에서 분리된 기냉매는 응축기(3)를 통해 수액기(4), 팽창밸브(5), 증발기(6)를 경유하면서 열교환을 행한 후 압축기(1)로 유입되는 싸이클을 행하게 되고 동시에 오일분리기(2)에서 분리된 오일은 오일반환통로를 통해 압축기(1)의 흡입측으로 유동하면서 증발기(6)에서 압송된 냉매와 함께 혼합되어 재차 압축기(1)로 유입된 후 압축기의 습동부분을 윤할하게 된다.The air refrigerant separated from the oil separator (2) undergoes a heat exchange while passing through the condenser (3) through the receiver (4), the expansion valve (5), and the evaporator (6), and then cycles into the compressor (1). And at the same time, the oil separated from the oil separator (2) flows to the suction side of the compressor (1) through the oil return passage, is mixed with the refrigerant pumped from the evaporator (6), flows into the compressor (1) again, and then the compressor slides. The part is polished.

도 2는 본 발명에 따른 오일분리기의 평단면도이고, 도 3은 오일분리기의 종단면도를 보이고 있다.Figure 2 is a plan sectional view of an oil separator according to the present invention, Figure 3 shows a longitudinal sectional view of the oil separator.

전체를 부호 2로 표시한 오일분리기는 상,하부가 개구된 관체형상의 본체(7)를 갖으며, 외주면에 양측에는 입구파이프(14)와 출구파이프(15)가 결합되는 입구공(7a)과 출구공(7b)이 서로 대향하고 있다.The oil separator, which is indicated by the entire symbol 2, has a tubular body 7 having upper and lower openings, and an inlet hole 7a to which an inlet pipe 14 and an outlet pipe 15 are coupled to both sides on an outer circumferential surface thereof. And the exit hole 7b face each other.

본체(7)의 개구부는 각각 상캡(9)과 하캡(10)에 의해 밀폐시켜 오일분리실(8)의 공간을 형성하고 있다.The opening of the main body 7 is sealed by the upper cap 9 and the lower cap 10, respectively, to form a space of the oil separation chamber 8.

상캡(9)의 저면 중앙에는 오일분리실(8)을 수직으로 구획하는 배플(11)이 하방으로 돌설되어 있으며, 상기 배플(11)의 끝단은 오일분리실(8)의 저면으로부터 소정거리 이격되어 오일분리실(8)의 내부 단면이 Ｕ자형의 오일.냉매 혼합기체의 유동 경로를 갖게 된다.A baffle 11 for vertically dividing the oil separation chamber 8 protrudes downward in the center of the bottom of the upper cap 9, and an end of the baffle 11 is spaced a predetermined distance from the bottom of the oil separation chamber 8. Thus, the inner cross section of the oil separation chamber 8 has a flow path of the U-shaped oil-refrigerant mixture gas.

이러한 Ｕ형의 경로는 냉매.오일 혼합기체가 배플(11)의해 Ｕ턴할 때 원심력에 의해 오일을 분리하게 된다.This X-shaped path separates the oil by centrifugal force when the refrigerant / oil mixture gas is turned by the baffle 11.

하캡(10)은 중앙에 두께방향으로 오일배출구(10a)가 형성되어 있으며, 오일배출구(10a)의 단부에는 필터(12)를 체결하여 오일속에 포함된 이물질을 여과함으로써 오일통로가 막히는 것을 방지하도록 하고 있다.The lower cap 10 has an oil outlet 10a formed in the thickness direction at the center thereof, and fastens the filter 12 at the end of the oil outlet 10a to filter foreign substances contained in the oil to prevent the oil passage from being blocked. Doing.

오일분리실(8)에는 압축기(1)로부터 토출된 냉매.오일 혼합기체로부터 냉매와 오일을 분리하기 위한 분리망(13)이 설치되어 있다.The oil separation chamber 8 is provided with a separation network 13 for separating the refrigerant and oil from the refrigerant / oil mixture gas discharged from the compressor 1.

더욱이 분리망(13)은 미세한 세선을 직조한 것으로 일측이 입구파이프(14)의 내부로 삽입되고, 타측이 배플(11)에 접하고 있으며, 도 4와 같이 나선형상으로 감긴채로 설치함으로써 오일분리 성능을 높일 수 있다.In addition, the separation net 13 is a fine fine wire woven, one side is inserted into the inlet pipe 14, the other side is in contact with the baffle 11, oil separation performance by installing in a spiral wound as shown in FIG. Can increase.

도면중 미설명 부호 16,17은 압축기의 토출측과 입구파이프(14)를 연결하고, 또한 출구파이프(15)와 응축기(3)의 흡입측과 연결하기 위한 연결블록들을 도시한 것이다.In the drawings, reference numerals 16 and 17 show connection blocks for connecting the discharge side of the compressor and the inlet pipe 14, and also for connecting the outlet pipe 15 and the suction side of the condenser 3.

이하, 작용을 설명한다. 압축기(1)에서 배출되는 고온.고압의 냉매.오일 혼합기체에서 오일은 안개와 같이 작은 방울로 섞여 유동한다. 오일분리기(2)의 내부는 입구파이프(14)에 비해 유동단면적이 확대되는 형상으로 되어 있어 오일분리실(8)로 유입된 냉매.오일 혼합기체는 유속이 감속되면서 분리망(13)을 통과하므로써 오일의 작은 입자들이 뭉치게 된다.The operation will be described below. In the high-temperature, high-pressure refrigerant / oil mixture gas discharged from the compressor (1), the oil is mixed into small droplets such as mist and flows. The inside of the oil separator 2 has a shape in which the cross sectional area of the oil separator 2 is enlarged compared to the inlet pipe 14, and the refrigerant and oil mixed gas introduced into the oil separation chamber 8 passes through the separation network 13 while the flow rate is reduced. This causes small particles of oil to clump together.

더욱이 분리망(13)은 나선형상으로 감겨진 상태로 설치되므로 상대적으로 냉매.오일 혼합기체가 분리망(13)에 접하는 면적이 증대되어 오일분리력이 높아진다.Furthermore, since the separation net 13 is installed in a spirally wound state, the area in which the refrigerant / oil mixture gas contacts the separation net 13 is increased, thereby increasing the oil separation force.

이와 같이 뭉쳐진 오일은 오일방울을 형성하면서 비산되거나 중력에 의해 오일분리실(8)로 하부로 낙하된다. 이때 비산된 오일방울은 오일분리실(8)의 벽면이나 배플(11)에 달라 붙고 이들은 중력에 의해 하방으로 이동하면서 오일분리실(8) 하부에 집유된다.The oil thus aggregated is scattered while forming oil droplets or falls downward into the oil separation chamber 8 by gravity. At this time, the scattered oil droplets are attached to the wall or baffle 11 of the oil separation chamber 8 and they are collected under the oil separation chamber 8 while moving downward by gravity.

오일방울중 일부는 혼합기체의 흐름에 따라 유동하게 되는데 오일분리실(8) 중앙에 형성된 배플(11)에 의해 Ｕ턴 하면서 이때 발생하는 강한 원심력에 의해 이탈되어 낙하하게 된다.Some of the oil droplets are flowed according to the flow of the mixed gas, but by the baffle 11 formed in the center of the oil separation chamber 8 is separated by the strong centrifugal force generated at this time to fall.

혼합기체가 유동하는 Ｕ턴 부위는 유동 단면적이 줄어 들기 때문에 상대적으로 유속이 빨라 강한 원심력이 나타난다. 혼합기체가 입구파이프(14)를 지나서 오일분리실(8)로 유입될 때 공간이 넓어지므로 유동의 속도가 감속하면서 분리망(13)에 의해 안개상태의 오일이 방울로 뭉치게 되고 오일분리실(8)의 하방으로 Ｕ턴 할 때 유속이 증가되면서 원심력이 극대화 된다.Because of the reduced cross sectional area, the flow area of the Ｕton where the mixed gas flows has a relatively high flow velocity, resulting in strong centrifugal force. When the mixed gas enters the oil separation chamber 8 through the inlet pipe 14, the space becomes wider, so that the oil flows in a mist by the separation network 13 as the flow velocity decreases, and the oil separation chamber At the bottom of (8), the flow rate increases and the centrifugal force is maximized.

따라서 오일방울은 원심력에 혼합기체의 경로로부터 이탈하여 하부로 낙하되고 동시에 기냉매는 오일분리실(8)의 출구파이프(15)를 향해 유동한다.Therefore, the oil droplets are separated from the path of the mixed gas by centrifugal force and fall downward, and at the same time, the air coolant flows toward the outlet pipe 15 of the oil separation chamber 8.

즉, 본 발명은 혼합기체로부터 오일을 분리함에 있어서, 분리망(13)에 의해 방울형태로 뭉쳐진 오일입자들은 오일분리실(8) 유입시 유동에 의해 1차적으로 비산되고 2차적으로 배플(11)에 의해 Ｕ턴시 원심력과 오일방울의 중력에 의해 혼합기체로부터 분리된다.That is, in the present invention, in the oil separation from the mixed gas, the oil particles aggregated in the form of droplets by the separation network 13 are first scattered by the flow when the oil separation chamber 8 is introduced and the baffle 11 is secondary. It is separated from the mixed gas by the centrifugal force at the nominal force and the gravity of the oil droplets.

원심력과 중력은 모두 질량에 비례하는 힘으로 냉매.오일 혼합기체에서 고온.고압의 냉매기체에 비해 오일방울의 질량이 크므로 원심력과 중력이 크게 작용하게 된다. 또한 원심려과 중력이 작용하는 바향이 오일분리실(8) 하부를 향한 방향과 일치하므로 오일분리 성능이 극대화된다.Centrifugal force and gravity are both proportional to the mass, so the mass of oil droplets in the refrigerant / oil mixture gas is higher than that of the high-temperature / high pressure refrigerant gas. In addition, the direction in which the centrifugal lift and gravity acts coincide with the direction toward the bottom of the oil separation chamber 8 to maximize oil separation performance.

이상과 같은 원리에 의해 냉매.오일 혼합기체로부터 분리된 오일은 오일분리실(8) 하부에 집유된 후 오일배출구(10a)를 통해 압축기(1)의 흡입측으로 유동하게 된다. 이때 오일분리실(8) 저면에 집유된 오일에는 에어컨 가동시 발생하는 불순물 즉, 압축기(1)의 구동샤프트가 회전하면서 기계적 마찰 및 냉매라인의 부식에 의해 발생하는 미세입자들이 냉매와 함께 순환하면서 유입되어 오일속에 존재하게 되는데 본 발명은 오일배출구(10a)의 단부에 체결된 미세하게 직조된 필터(12)에 의해 필터링됨으로써 불순물이 압축기(1)로의 유입되지 않는다.According to the above principle, the oil separated from the refrigerant / oil mixture gas is collected in the lower portion of the oil separation chamber 8 and then flows to the suction side of the compressor 1 through the oil outlet 10a. At this time, the oil collected in the bottom surface of the oil separation chamber 8 contains impurities generated during the operation of the air conditioner, that is, fine particles generated by mechanical friction and corrosion of the refrigerant line as the driving shaft of the compressor 1 rotates, circulating together with the refrigerant. The present invention is introduced into the oil, but the present invention is filtered by the finely woven filter 12 fastened to the end of the oil outlet 10a so that impurities are not introduced into the compressor 1.

이후, 오일은 냉매회로를 순환하여 유입되는 냉매와 함께 혼합되어 압축기(1)의 흡입측으로 환원하는 순환과정을 연속적으로 반복하게 된다.Thereafter, the oil is continuously mixed with the refrigerant introduced by circulating the refrigerant circuit and reduced to the suction side of the compressor 1.

이상에서 설명한 바와 같이 본 발명은 비교적 구조가 간단한 오일분리기를 제작할 수 있고, 더욱이 분리망을 나선형상으로 감아 설치함으로써 오일분리 성능을 향상시킬 수 있다.As described above, the present invention can manufacture an oil separator having a relatively simple structure, and can further improve oil separation performance by installing the separation network in a spiral shape.
