Description
본 고안은 냉동설비에 사용되는 압축기의 실린더에 결합되는 냉매 흡입튜브에 관한 것으로, 특히 실린더 인입구에 강도가 우수한 강재로 구성된 흡입튜브를 직접 압입시킴으로서 자재비를 절감하고, 압입시 발생될 수 있는 스크래치를 방지하기 이하여 외면으로 무전해 니켈 코팅층을 형성하여 종래 동관에서 나타나는 연질에 의한 기밀성의 저하와 산화녹 발생을 예방토록 한 것이다.The present invention relates to a refrigerant suction tube coupled to a cylinder of a compressor used in a refrigeration system. In particular, by directly injecting a suction tube made of steel with high strength into the cylinder inlet, material costs can be reduced, and scratches that can be generated during indentation can be achieved. In order to prevent this, an electroless nickel coating layer was formed on the outer surface to prevent a decrease in airtightness due to the softness and the occurrence of rust oxide caused by the conventional copper tube.
종래에는 도 1에 도시된 바와 같이 압축기 실린더(10)로 삽착되어지는 흡입튜브(20)는 소정의 길이를 가지는 동관의 일단부를 상기 실린더(10)에 내접토록 한 후 상기 흡입튜브(20) 보다 약 0.05 밀리미터 정도의 큰 외경을 가지는 압입튜브(30)를 압입함으로서 내접된 실린더(10)와 흡입튜브(20)간에는 기밀이 유지되도록 하였다.Conventionally, as shown in FIG. 1, the suction tube 20 to be inserted into the compressor cylinder 10 has an end portion of the copper tube having a predetermined length internally in contact with the cylinder 10 and then the suction tube 20. The press-fit tube 30 having a large outer diameter of about 0.05 millimeter was press-fitted to maintain airtightness between the inscribed cylinder 10 and the suction tube 20.
이는 흡입튜브가 동관이기 때문에 압입시 정확한 기밀이 유지된 상태에서 압입되지 못하기 때문에 반듯이 압입튜브를 흡입튜브의 내측에 결합함으로서 기밀이 유지된 상태에서 결합토록 한 것이다.This is because the suction tube is a copper tube and cannot be press-fitted in a state where accurate air tightness is maintained, so the press-fit tube is coupled to the inside of the suction tube so that the airtight state is coupled.
그러나 이와 같은 흡입튜브 연결구조는 비교적 고가인 동관으로 제작된 흡입튜브(20)를 사용함으로서 제조 단가가 높다는 문제점과 별도로 가공된 압입튜브(30)를 필요로 한다는 문제점 및 압입튜브(30) 압입시 흡입튜브(20)가 쉽게 손상되는 문제점이 있었다.However, such a suction tube connection structure has a problem that the manufacturing cost is high by using a suction tube 20 made of a relatively expensive copper tube and requires a press-fit tube 30 that is processed separately, and press-fit the press-fit tube 30. There was a problem that the suction tube 20 is easily damaged.
본 고안은 상기한 종래의 문제점을 해결하기 위하여 안출한 것으로서, 비교적 저렴한 강재로 구성된 흡입 튜브의 외경을 실린더 내경보다 약간 크게 제조하고 그 외주면에 코팅층을 형성하여 외접되는 실린더와의 기밀성을 향상시키고 재료비의 절감을 이루도록 한 것이다.The present invention has been made to solve the above-described problems, the outer diameter of the suction tube made of relatively inexpensive steel is made slightly larger than the inner diameter of the cylinder and the coating layer is formed on the outer peripheral surface to improve the airtightness with the outer cylinder and material cost To achieve the savings.

이하에서는 첨부 도면을 참조하여 본 고안의 가장 바람직한 일 실시 예를 상세히 설명하기로 한다. 우선, 각 도면을 설명함에 있어, 동일한 구성 요소들에 한해서는 비록 다른 도면상에 도시되더라도 가능한 한 동일한 참조부호를 갖는다.Hereinafter, with reference to the accompanying drawings will be described in detail the most preferred embodiment of the present invention. First, in describing each of the drawings, the same components have the same reference numerals as much as possible even though they are shown in different drawings.
제 2도에 도시한 바와 같이 본 고안에 따른 압축기 흡입 튜브는 양단부의 직경이 상이하게 제작된 강재의 흡입튜브(20)가 압축기 실린더(10) 개구부에 내삽되어지는 구성이다.As shown in FIG. 2, the compressor suction tube according to the present invention has a configuration in which a suction tube 20 made of steel having different diameters at both ends is inserted into the compressor cylinder 10 opening.
상기 흡입튜브(20)의 외면에는 표면경도를 높이고 기밀성을 높이기 위해 무전해 니켈 코팅을 행함으로서 코팅층(24)이 형성된다.On the outer surface of the suction tube 20, the coating layer 24 is formed by performing electroless nickel coating to increase the surface hardness and the airtightness.
이때 상기 흡입 튜브(20)의 외면으로 형성되는 코팅층(24)은 삽입되는 일부에 형성되거나 튜브 전체에 균일하게 형성될 수도 있는 것이다.In this case, the coating layer 24 formed on the outer surface of the suction tube 20 may be formed on a part to be inserted or uniformly formed on the entire tube.
무전해로 행하여지는 니켈코팅층(24)은 모재에 내열성과 열전도성, 용접성, 납땜성 및 변색 등을 방지하는 열적 특성이 부가됨으로서 니켈코팅층(24)을 가지는 강관으로 이루어진 흡입튜브(20)는 압축기 실린더(10) 내로의 압입시 표면으로 일어나는 흠집의 발생을 억제함으로서 냉매의 누설이 방지될 수 있도록 한 것이다.The electroless nickel coating layer 24 is made of a steel tube having the nickel coating layer 24 by adding a thermal property to the base material to prevent heat, thermal conductivity, weldability, solderability, and discoloration. It is to prevent the leakage of the refrigerant by suppressing the occurrence of scratches occurring on the surface during the press-fit into the cylinder (10).
또한 상기 무전해 니켈 코팅층(24)은 코팅층을 형성하기 위한 방법으로 전해에 의한 방법을 사용할 수도 있으나 균일하고 후박한 두께를 갖도록 할 수 있는 무전해 코팅 방법이 바람직하다 할 것이나 도금 기술의 발달 등으로 인하여 변경될 수도 있는 것이다.In addition, the electroless nickel coating layer 24 may be an electrolytic method as a method for forming a coating layer, but an electroless coating method that may have a uniform and thick thickness may be preferable, but due to the development of plating technology, etc. It may be changed.
상기 코팅층(24)을 이루는 니켈은 이와 동등한 접합성과 기밀성을 향상시킬 수 있고 열변형을 방지할 수 있도록 한 구리 또는 복합은 등을 사용하여 피복되어질 수도 있으나 현재로서는 비교적 저렴한 니켈의 사용이 바람직하다.Nickel constituting the coating layer 24 may be coated using a copper or a composite silver or the like to improve the equivalent bonding and airtightness and to prevent thermal deformation, but at this time it is preferable to use a relatively inexpensive nickel.
상기 흡입튜브(20)의 큰 직경을 가지는 단부는 압축기 케이스(100) 측벽에 형성된 흡입공(120)으로 삽입되어지고 작은 직경을 가지는 단부는 압축기실린더(10)에 내접되어 압입되어진다.The end having the large diameter of the suction tube 20 is inserted into the suction hole 120 formed in the side wall of the compressor case 100 and the end having the small diameter is inscribed in the compressor cylinder 10 and press-fitted.
이때 작은 직경의 흡입튜브(20) 외경은 실린더 내경보다 약간 크게(약 0.05밀리미터) 형성됨으로서 압입 후 순환되는 냉매가 누설되지 않도록 되어있다.At this time, the outer diameter of the small diameter suction tube 20 is slightly larger (about 0.05 millimeter) than the inner diameter of the cylinder, so that the refrigerant circulated after the press-fitting does not leak.
상술한 바와 같이 행하여진 압축기 흡입튜브는 실린더에 압입되는 흡입튜브의 재질을 강재로 구성하여 제작 단가를 낮추고 별도로 제조되어 소요되던 압입튜브의 사용을 필요없도록 함으로서 제작비가 절감되는 효과와 공정 단축의 효과가 있는 것이다.Compressor suction tube made as described above is made of the material of the suction tube press-fitted to the cylinder made of steel to reduce the manufacturing cost and to eliminate the need for the use of the press-fitted tube that was manufactured separately, the effect of reducing the manufacturing cost and the effect of shortening the process There is.
상술한 바와 같이 본 고안의 압축기 흡입튜브는 부품수를 절감하고 비교적 저렴한 강재의 사용으로 제작단가를 낮추고 제조공정을 단축하여 생산성을 높일 수 있다는 효과가 있는 것이다.As described above, the compressor suction tube of the present invention has the effect of reducing the number of parts and using a relatively inexpensive steel to lower the manufacturing cost and shorten the manufacturing process to increase productivity.
