Description

냉매 공급관{REFRIGERANT SUPPLY PIPE}Refrigerant supply pipe {REFRIGERANT SUPPLY PIPE}

본 발명은 냉매 공급관에 관한 것으로서, 더욱 상세하게는 냉매관과 모세관이 이음부가 없는 단일체로 이루어진 냉매 공급관에 관한 것이다.The present invention relates to a refrigerant supply pipe, and more particularly, to a refrigerant supply pipe made of a single body in which a refrigerant pipe and a capillary tube have no joint.

일반적으로 냉장고, 에어컨, 정수기 등에는 냉각을 위하여 냉동 사이클이 제공된다. 통상적으로 사용되고 있는 냉동 사이클은 압축기와 응축기가 파이프로 연결되고, 응축기와 증발기는 냉매 공급관을 거쳐 모세관으로 연결되며, 증발기와 압축기는 흡입파이프로 연결된다.In general, refrigerators, air conditioners, water purifiers, etc. are provided with a refrigeration cycle for cooling. Commonly used refrigeration cycle is a compressor and a condenser is connected to the pipe, the condenser and the evaporator is connected to the capillary via a refrigerant supply pipe, the evaporator and the compressor is connected to the suction pipe.

이러한 냉동 사이클은 압축기에서 압축되어 토출된 고온,고압의 냉매가스는 응축기로 유입되고, 응축기로 유입된 냉매가스는 응축기에서 방열을 하여 냉매온도가 낮추어 지며, 냉매가 응축기의 고압을 저압으로 낮추는 모세관으로 다시 토출되어 압력이 낮아진 냉매가 다시 증발기로 유입되는 과정으로 진행된다.In this refrigeration cycle, the high-temperature and high-pressure refrigerant gas discharged from the compressor is introduced into the condenser, and the refrigerant gas introduced into the condenser radiates heat from the condenser to lower the refrigerant temperature. The refrigerant is discharged again and the pressure is lowered to proceed to the evaporator flows back.

이와 같은 모세관이 포함된 종래의 냉매 공급관은 도 1에 도시된 바와 같이 냉매관(10)과, 이 냉매관(10)과 연결되는 연결관(20)과, 이 연결관(20)과 연결되는 모세관(30)으로 이루어진다.As shown in FIG. 1, the conventional refrigerant supply pipe including the capillary is connected to the refrigerant pipe 10, the connection pipe 20 connected to the refrigerant pipe 10, and the connection pipe 20. It consists of a capillary tube 30.

상기 냉매관(10), 연결관(20), 모세관(30)은 동 파이프 등으로 이루어지며, 상기 냉매관(10)의 내경은 연결관(20) 외경보다 크게 이루어지며, 상기 모세관()의 외경은 연결관()의 내경보다 작게 이루어진다.The refrigerant pipe 10, the connection pipe 20, the capillary tube 30 is made of a copper pipe, etc., the inner diameter of the refrigerant pipe 10 is made larger than the outer diameter of the connection pipe 20, the The outer diameter is made smaller than the inner diameter of the connecting pipe ().

이러한 냉매 공급관은 냉매관(10)의 일측 내부로 연결관(20)을 삽입한 상태로 용접하여 냉매관(10)과 연결관(20)을 연결하고, 연결관(20)의 타측 내부로 모세관(30)을 삽입한 상태로 용접하여 연결한다.The refrigerant supply pipe is welded in a state where the connecting pipe 20 is inserted into one side of the refrigerant pipe 10 to connect the refrigerant pipe 10 and the connection pipe 20, and the capillary pipe into the other side of the connection pipe 20. (30) is inserted and welded.

상기에서 연결관(20)을 사용하는 이유는 냉매관(10)과 모세관(30)의 관로 직경이 큰 차이가 나므로 이들을 용접으로 서로 연결할 수 없어 연결관을 사용하게 된다.The reason for using the connection pipe 20 in the above is because the diameter of the pipe line of the refrigerant pipe 10 and the capillary tube 30 is large difference, so they can not be connected to each other by welding, the connection pipe is used.

그러나 이와 같은 냉매 공급관은 서로 관로의 직경이 다른 냉매관(10), 연결관(20), 모세관(30)을 용접으로 서로 연결하게되므로 냉매 공급관의 제작에 많은 시간이 소요되며, 또 제작된 냉매 공급관에 외부 충격 등이 가해지면 용접으로 연결된 부위에 틈이 생겨 냉매가 유출될 가능성이 있다.However, since such refrigerant supply pipes connect the refrigerant pipes 10, the connection pipes 20, and the capillary tube 30 having different diameters to each other by welding, it takes a lot of time to produce the refrigerant supply pipes. If an external shock or the like is applied to the supply pipe, a gap may be generated in the welded part and the refrigerant may leak out.

본 발명은 상기한 바와 같은 종래의 문제점을 해결하기 위하여 제안된 것으로서, 본 발명의 목적은 냉매관과 모세관이 연결관 없이 단일관으로 이루어진 냉매 공급관을 제공하는데 있다.The present invention has been proposed to solve the conventional problems as described above, an object of the present invention is to provide a refrigerant supply pipe consisting of a single pipe without a refrigerant pipe and a capillary tube.

본 발명이 제안하는 냉매 공급관은,The refrigerant supply pipe proposed by the present invention,

냉동 사이클에 제공되어 냉매가 흐르는 냉매관 및 이 냉매관의 일측에 연결 되는 모세관을 포함하고,A refrigerant pipe provided in the refrigeration cycle and a refrigerant pipe through which the refrigerant flows, and a capillary tube connected to one side of the refrigerant pipe,

상기 냉매관과 모세관은 관로의 내경이 다르게 이루어지면서 이음부가 없는 단일관으로 형성된 것을 특징으로 하는 냉매 공급관을 제공한다.The refrigerant pipe and the capillary tube are provided with a refrigerant supply pipe, characterized in that the inner diameter of the pipe is made different, formed as a single tube without a joint.

상기 냉매관과 모세관 사이는 연결부로 이루어지며, 이 연결부는 경사면으로 형성된다.The refrigerant pipe and the capillary are formed by a connecting portion, and the connecting portion is formed as an inclined surface.

본 발명에 의한 냉매 공급관은, 냉매관과 모세관이 연결부위 없이 단일관로로 이루어지므로 제조를 간단하게 할 수 있으면서, 아울러 연결부가 없어 외력이 가해져도 냉매가 유출될 가능성이 없다.In the refrigerant supply pipe according to the present invention, since the refrigerant pipe and the capillary tube are made up of a single pipe without a connecting portion, the refrigerant can be simplified, and there is no possibility that the refrigerant flows out even when an external force is applied without a connecting portion.

이하, 본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 더욱 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in more detail.

도 2는 본 발명에 의한 냉매 공급관의 정면도이고, 도 3은 본 발명에 의한 냉매 공급관의 주요부분 확대 단면도로서, 본 발명에 의한 냉매 공급관은 냉매관(2)과, 이 냉매관(2)의 일측으로 연장되는 모세관(4)을 포함한다.FIG. 2 is a front view of the refrigerant supply pipe according to the present invention, and FIG. 3 is an enlarged cross-sectional view of a main portion of the refrigerant supply pipe according to the present invention. The refrigerant supply pipe according to the present invention includes a refrigerant pipe 2 and the refrigerant pipe 2. It includes a capillary tube 4 extending to one side.

상기 냉매관(2)과 모세관(4)은 동 파이프 등으로 이루어지며 통상적인 냉매 사이클에서 사용될 수 있다.The refrigerant tube 2 and the capillary tube 4 are made of copper pipes and the like, and can be used in a conventional refrigerant cycle.

상기 냉매관(2)은 모세관(4)에 비하여 큰 내경을 갖추며, 냉매관(2)과 모세관(4) 사이는 연결부(6)로 연결되어 있다.The coolant tube 2 has a larger inner diameter than the capillary tube 4, and is connected between the coolant tube 2 and the capillary tube 4 by a connecting portion 6.

본 발명의 특징은 이와 같은 냉매 공급관이 단일체로 이루어진다. 즉 냉매 관(2)과 모세관(4)은 하나의 관로로 이루어지면서 내경이 다른 연결부(6)로 연결된 형태로 이루어진다.Characteristic of the present invention is such a refrigerant supply pipe is made of a single body. That is, the refrigerant pipe (2) and the capillary tube (4) is made of a single pipe, while the inner diameter is connected to the other connecting portion (6).

따라서 이러한 냉매관(2) 모세관(4)은 연결부(6)로 연결된 단일체로 이루어진다. 상기 연결부(6)는 경사면으로 형성되어 냉매관(2)과 모세관(4)이 일체로 이루어지면서 서로 연결되도록 되어있다.Therefore, the refrigerant pipe (2) capillary (4) is made of a single body connected by the connecting portion (6). The connecting portion 6 is formed in an inclined surface so that the refrigerant pipe 2 and the capillary tube 4 are integrally formed and connected to each other.

이와 같은 냉매 공급관의 제작은, 소정의 직경을 갖는 동 파이프를 점차적으로 좁아지도록 내측에 테이퍼 면을 갖는 인발용 다이스를 통과시켜 인발하면 냉매관(2)으로부터 소정의 직경으로 줄어들면서 모세관(4)이 형성된다. 그리고 냉매관(2)과 모세관(4) 사이는 경사면으로 이루어진 연결부(6)로 형성된다.In the production of such a coolant supply pipe, the capillary tube 4 is reduced to a predetermined diameter from the coolant tube 2 when drawn through a drawing die having a tapered surface inside so as to gradually narrow a copper pipe having a predetermined diameter. Is formed. And between the refrigerant tube 2 and the capillary tube 4 is formed by a connecting portion 6 consisting of an inclined surface.

이렇게 냉매관(2)과 모세관(4)이 연결부위 없이 일체형으로 이루어지면 냉매 공급관의 제작을 간단하게 할 수 있고, 또 연결부분이 없어 냉매 공급관에 외부 충격 등이 가해지더라도 틈이 생기지 않아 냉매의 유출 가능성이 없다.Thus, if the refrigerant pipe 2 and the capillary tube 4 are integrally formed without connecting parts, the production of the refrigerant supply pipe can be simplified, and there is no connection part, so even if an external shock or the like is applied to the refrigerant supply pipe, there is no gap. There is no possibility of leakage.

이러한 냉매 공급관의 냉매관(2)은 도시되지 않은 냉동 사이클의 응측기 쪽에 연결되고 모세관(4)은 증발기 쪽에 연결하면 된다.The refrigerant pipe 2 of the refrigerant supply pipe may be connected to the side of the condenser of the refrigeration cycle (not shown), and the capillary tube 4 may be connected to the evaporator side.

이렇게 연결된 냉매 공급관은 응측기에서 변화된 고온고압의 액체냉매가 냉매관(2)을 통하여 연결관(6)을 거쳐 모세관(4)을 지나면서 팽창되어 저온저압의 액체냉매로 변화되어 공급되므로 소정의 냉각효과를 발휘하게 된다.The connected refrigerant supply pipe is a high temperature and high pressure liquid refrigerant, which is changed in the condenser, expands through the connection pipe 6 through the refrigerant pipe 2, passes through the capillary tube 4, and is converted into a low temperature low pressure liquid refrigerant. Cooling effect is exerted.
