이하, 본 발명의 바람직한 일실시예를 첨부도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

참고적으로, 이하에서 설명될 본 발명의 구성들 중 종래기술과 동일한 구성 에 대해서는 전술한 종래기술을 참조하기로 하고 별도의 상세한 설명은 생략한다.For reference, among the configurations of the present invention to be described below, the same configuration as the prior art will be referred to the above-described prior art, and a detailed description thereof will be omitted.

도 2는 본 발명의 바람직한 실시예에 따른 모세관 사시도이다.2 is a perspective view of a capillary tube according to a preferred embodiment of the present invention.

도 2에 도시된 바와 같이, 본 실시예의 모세관은, 제1권선부(103)와, 상기 제1권선부(103)의 권선되는 축(A)과 엇갈리는 축(B)을 중심으로 권선되는 제2권선부(104)를 포함하여 이루어진다.As shown in FIG. 2, the capillary tube according to the present embodiment includes a first winding part 103 and a winding wound about an axis B that is crossed with a winding axis A of the first winding part 103. It consists of two windings 104.

제1권선부(103)는 입구(101)에 근접하도록 배치되며, 권선되는 축(A)이 수평하게 배치된다.The first winding part 103 is disposed to be close to the inlet 101, and the winding axis A is disposed horizontally.

제1권선부(103)는 동일한 권선반경(r)을 가진 원형상으로 복수번 권선되어 코일형상으로 형성된다.The first winding part 103 is wound a plurality of times in a circular shape having the same winding radius r to form a coil shape.

제1권선부(103)의 출구측 관은 후방으로 절곡되어 절곡부(105)가 형성된다.The outlet side pipe of the first winding part 103 is bent backward to form a bent part 105.

절곡부(105)의 끝단에 제1권선부(103)의 권선되는 축(A)과 엇갈리는 축(B)을 중심으로 권선되는 제2권선부(104)가 연결된다. 즉, 제2권선부(104)의 축(B)은 제1권선부(103)의 축(A)과 평행하지 않게 형성된다. 바람직하게는, 본 실시예에서와 같이 제2권선부(104)의 축(B)은 제1권선부(103)의 축(A)과 수직하게 형성된다. 이와 같이 제1권선부(103)는 제2권선부(104)보다 상류에 배치되어, 냉매의 회전력 및 진동을 더욱 효과적으로 감소시킨다.At the end of the bent portion 105, a second winding portion 104 wound around the axis A of the first winding portion 103 and the crossing axis B is connected. That is, the axis B of the second winding part 104 is formed not to be parallel to the axis A of the first winding part 103. Preferably, as in the present embodiment, the axis B of the second winding portion 104 is formed perpendicular to the axis A of the first winding portion 103. In this manner, the first winding part 103 is disposed upstream of the second winding part 104 to more effectively reduce the rotational force and vibration of the refrigerant.

제2권선부(104)는 제1권선부(103)의 입구측 근접하도록 배치된다. 따라서, 제2권선부(104)의 입구는 제2권선부(104)의 출구보다 하부에 배치된다.The second winding part 104 is disposed to be close to the inlet side of the first winding part 103. Therefore, the inlet of the second winding part 104 is disposed below the outlet of the second winding part 104.

또한, 제1권선부(103)의 권선횟수보다 제2권선부(104)의 권선횟수가 작도록 제2권선부(104)는 동일한 권선반경(R)으로 권선된다.In addition, the second winding unit 104 is wound with the same winding radius R so that the winding number of the second winding unit 104 is smaller than the winding number of the first winding unit 103.

나아가, 제1권선부(103)의 권선반경(r)은 제2권선부(104)의 권선반경(R)보다 작도록 제2권선부(104)는 형성된다.Further, the second winding part 104 is formed such that the winding radius r of the first winding part 103 is smaller than the winding radius R of the second winding part 104.

제2권선부(104)의 관직경은 최소 5mm로 형성되어, 제1권선부(103)의 직경보다 크게 형성된다.The tubular diameter of the second winding part 104 is formed to be at least 5mm, larger than the diameter of the first winding part 103.

도 4에 도시된 바와 같이, 제2권선부(104)는 동심원형상으로 권선되도록 권선반경(R)이 점점 작아지도록 권선되도록 할 수 있다. As shown in FIG. 4, the second winding part 104 may be wound so that the winding radius R becomes smaller to be wound in a concentric shape.

또는, 도 5에 도시된 바와 같이, 제2권선부(104)의 권선형상을 타원형으로 권선시켜 유속이 더욱 효과적으로 감소되도록 할 수 있다.Alternatively, as shown in FIG. 5, the winding shape of the second winding part 104 may be wound in an elliptical shape so that the flow velocity may be more effectively reduced.

이러한 모세관은 냉매가 제1권선부(103)를 통과하면서 감압 팽창되게 되고, 이어서 제2권선부(104)를 통과하면서 유속이 감속되어 도 3의 실험데이터(개선후)에 나타나는 바와 같이 와류 및 진동, 냉매 유음이 발생되는 것을 방지된다.The capillary tube expands under reduced pressure as the refrigerant passes through the first winding part 103, and then decreases in flow velocity as it passes through the second winding part 104, as shown in the experimental data (after improvement) of FIG. 3. Vibration and coolant noise are prevented from occurring.
