본 발명은 냉각장치용 파이프에 관한 것으로서, 보다 상세하게는 콤팩트한 크기로 제작되어도 열교환이 효과적으로 이루어지도록 된 새로운 구조의 열교환기에 관한 것이다. The present invention relates to a pipe for a cooling device, and more particularly, to a heat exchanger having a new structure such that heat exchange is effectively performed even when manufactured in a compact size.

열교환기는 고온유체가 가진 열에너지를 저온유체로 보내는 장치로, 흔히, 가열기·냉각기·증발기·응축기 등에 사용된다. 이러한 열교환기는 유체의 종류에 따라 다양한 타입이 제공되고 있기는 하지만, 일반적으로는 내관체와 외관체의 이중관체로 이루어져서 내관체와 외관체 내부로 유체가 이송됨에 따라 열교환이 이루어지도록 구성된다. Heat exchangers are devices that send the thermal energy of a high-temperature fluid to a low-temperature fluid, and are commonly used in heaters, coolers, evaporators, condensers, and the like. Although various types of heat exchangers are provided according to the type of fluid, the heat exchanger is generally composed of a double tube of an inner tube and an outer body so that heat exchange occurs as the fluid is transferred into the inner tube and the outer body.

이러한 열교환기에 있어서 열교환효율은 고온유체와 저온유체의 접촉시간과 접촉면적 등에 영향을 받는데, 전술한 바와 같은 단순한 이중관체타입은 고온유체와 저온유체가 각각 직선상으로 이송되므로 유체들이 상대적으로 넓은 전열면적을 확보하지 못하므로 효과적으로 열교환이 이루어지지 못하는 단점이 있다. In such a heat exchanger, the heat exchange efficiency is influenced by the contact time and the contact area of the high temperature fluid and the low temperature fluid. In the simple double tube type as described above, since the high temperature fluid and the low temperature fluid are transferred in a straight line, the fluids are relatively large in heat transfer. There is a disadvantage that the heat exchange can not be made effectively because the area is not secured.

그리고 이러한 문제점으로 인해 종래의 열교환기는 유체들이 넓은 전열면적을 확보하도록 하기 위해 열교환기의 길이가 길게 연장 형성되는 등 열교환기의 부피가 크게 제작된다. And, due to this problem, the heat exchanger of the conventional heat exchanger has a large volume of the heat exchanger, such that the length of the heat exchanger is extended to be formed to secure a large heat transfer area.

본 발명은 상기의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 고온유체와 저온유체가 이송되는 경로가 우회로를 이루도록 되어 유체들이 상대적으로 넓은 전열면적을 확보할 수 있도록 되어 콤팩트한 크기로 제작되어도 열교환효율이 우수한 새로운 구조의 열교환기를 제공하는 것이다.
The present invention is to solve the above problems, the object of the present invention is to make the path to the high temperature fluid and the low temperature fluid is bypassed so that the fluids can secure a relatively large heat transfer area even if manufactured in a compact size It is to provide a heat exchanger of a new structure with excellent heat exchange efficiency.

본 발명에 따르면, 제1열매체가 이송되는 내관체(10)와, 상기 제1열매체에 의해 열교환되는 제2열매체가 이송되며 상기 내관체(10)의 둘레부에 씌워지는 외관체(20)와, 상기 내관체(10)의 외주면과 외관체(20)의 내주면에 접하도록 상기 외관체(22) 내에 나선형상으로 구비되는 가이드부재(30)를 포함하여 이루어져서, 상기 유로(22)로 이송되는 제2열매체는 상기 가이드부재(30)에 의해 나선형의 우회로를 형성하도록 된 것을 특징으로 하는 열교환기가 제공된다. According to the present invention, the inner tube body 10 to which the first heat medium is conveyed, the second heat medium which is heat-exchanged by the first heat medium are conveyed, and the outer body body 20 covered by the circumference of the inner tube body 10 and And a guide member 30 provided in a spiral shape in the exterior body 22 so as to be in contact with the outer peripheral surface of the inner tube body 10 and the inner peripheral surface of the exterior body 20, thereby being transferred to the flow path 22. The second heat medium is provided with a heat exchanger, characterized in that to form a spiral bypass by the guide member (30).

본 발명의 다른 특징에 따르면, 상기 가이드부재(30)는 이중스크류 또는 관체로 이루어져서, 상기 유로(22)내에는 제2열매체가 순방향으로 이송되는 제1유로(23)와, 상기 제1유로(23)사이에 형성되어 이 제1유로(23)를 통해 이송된 제2열매체가 역방향으로 이송되는 제2유로(24)가 형성되는 것으로 특징으로 하는 열교환기가 제공된다. According to another feature of the invention, the guide member 30 is made of a double screw or tubular body, the first flow path 23 and the second flow path in which the second heat medium is forwarded in the flow path 22, and the first flow path ( A heat exchanger is provided, characterized in that a second flow passage (24) formed between the first flow passages (23) and the second heat medium transferred through the first flow passage (23) is formed in a reverse direction.

이하, 본 발명의 바람직한 실시예를 첨부한 도면에 의거하여 설명하면 다음과 같다. 도 1은 본 발명의 일 실시예를 보인 단면도로서, 본 발명은 도시된 바와 같이, 제1열매체가 이송되는 내관체(10)와, 상기 제1열매체에 의해 열교환되는 제2열매체가 이송되는 유로(22)가 상기 내관체(10)의 둘레부에 형성되도록 상기 내관체(10)에 씌워지는 외관체(20)와, 상기 내관체(10)의 외주면과 외관체(20)의 내주면에 접하도록 상기 유로(22) 내에 결합되는 나선형태의 가이드부재(30)를 포함하여 이루어진 열교환기이다. Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. 1 is a cross-sectional view showing an embodiment of the present invention, as shown in the present invention, the inner tube body 10, the first heat medium is transported, and the flow path for transporting the second heat medium heat exchanged by the first heat medium The outer body 20 which is overlaid on the inner tube body 10 so that 22 is formed at the circumference of the inner tube body 10, and the outer circumferential surface of the inner tube body 10 and the inner circumferential surface of the outer body 20. It is a heat exchanger comprising a guide member 30 of the spiral shape coupled to the flow passage 22 to.

상기 내관체(10)는 내부로 제1열매체가 이송되며, 상기 제1열매체는 냉매가스 등의 저온유체를 칭하는 것이다. 이러한 내관체(10)의 둘레부에는 외관체(20)가 씌워지며, 이 외관체(20)에 의해 내관체(10)의 둘레부에는 제2열매체가 이송되는 유로(22)가 형성된다. 상기 제2열매체는 제1열매체 의해 냉각되는 고온유체를 칭하하는 것이다. The inner tube body 10 transfers a first heat medium therein, and the first heat medium refers to a low temperature fluid such as refrigerant gas. The outer body 20 is covered with a circumference of the inner tube body 10, and a flow path 22 through which the second heat medium is transferred is formed at the circumference of the inner tube body 10 by the outer body 20. The second thermal medium refers to a high temperature fluid cooled by the first thermal medium.

그리고 상기 유로(22) 내에는 나선형태의 가이드부재(30)가 배치되는데, 가이드부재(30)는 내관체(10)의 외주면과 외관체(20)의 내주면에 접하도록 내관체(10)와 외관체(20)에 결합된다. 따라서 상기 유로(22) 내에는 가이드부재(30)에 의해 나선형의 우회로가 형성되고, 제2열매체는 이 우회로를 따라 이송된다. 이와 같이 제2열매체가 이송되는 유로(22)가 우회로를 형성함에 따라 제1열매체와 제2열매체이 상대적으로 넓은 면적으로 접촉되므로 열매체들의 전열면적이 넓게 확보되어제1, 2열매체 사이에 효과적인 열교환이 이루어진다.In addition, a spiral guide member 30 is disposed in the flow path 22, and the guide member 30 is in contact with an inner circumferential surface of the inner tube body 10 and an inner circumferential surface of the outer body 20. It is coupled to the exterior body 20. Accordingly, a spiral bypass is formed in the flow path 22 by the guide member 30, and the second thermal medium is transferred along the bypass. As the flow path 22 through which the second heat medium is transported forms a bypass, the first heat medium and the second heat medium are in contact with each other in a relatively large area, so that the heat transfer area of the heat medium is secured to widen the effective heat exchange between the first and second heat medium. Is done.

본 발명의 다른 실시예에 따르면, 상기 유로(22)는 나선형의 우회로를 형성함과 더불어 제2열매체가 순방향으로 이송되는 제1유로(23)와 다시 역방향으로 이송되는 제2유로(24)가 형성되어 열매체들의 상대적으로 더 넓은 전열면적을 가지도록 구성된다. 도 2는 그 일례를 보인 것으로, 상기 가이드부재(30)가 관체로 되어 이 가이드부재(30) 내부가 제2열매체가 순방향으로 이송되는 제1유로(23)가 되며, 상기 가이드부재(30)에 의해 내관체(10)와 외관체(20) 사이에 형성되는 나선형의 우회로는 상기 제1유로(23)를 통해 이송된 제2열매체가 역방향으로 이송되는 제2유로(24)가 된다. 따라서 제2열매체는 제1유로(23)인 가이드부재(30) 내부를 따라 나선형으로 이송되다가 제2유로(24)로 리턴되어 역방향으로 이송되므로 제1열매체와 제2열매체의 전열면적이 훨씬 더 넓어지므로 열교환효율이 상승된다. According to another embodiment of the present invention, the flow passage 22 forms a spiral bypass and the second flow passage 24, which is conveyed in the reverse direction from the first flow passage 23, in which the second heat medium is transferred in the forward direction. Formed and configured to have a relatively larger heat transfer area of the heating medium. 2 shows an example, wherein the guide member 30 is a tubular body, and the inside of the guide member 30 is a first flow path 23 through which the second heat medium is transferred in the forward direction, and the guide member 30. The spiral bypass formed between the inner tube body 10 and the outer body body 20 becomes a second channel 24 through which the second heat medium transferred through the first channel 23 is transferred in the reverse direction. Therefore, since the second heat medium is helically transferred along the inside of the guide member 30, which is the first flow path 23, and then returned to the second flow path 24, the heat transfer area of the first heat medium and the second heat medium is much higher. As it becomes wider, heat exchange efficiency is increased.

도 3은 가이드부재(30)가 관체로 이루어지지 않고 이중 스크류형태로 이루어져서, 제2열매체가 순방향으로 이송되는 제1유로(23)와, 역방향으로 이송되는 제2유로(24)가 형성되도록 된 구성이다. FIG. 3 shows that the guide member 30 is not made of a tubular body but has a double screw shape, such that a first flow path 23 through which the second heat medium is transferred in the forward direction and a second flow path 24 through which the reverse direction is formed are formed. Configuration.

도 4는 본 발명의 또 다른 실시예를 보인 것으로, 외관체(20)의 둘레부에 제1열매체가 리싸이클되는 유로(14)가 형성된 것이다. 이 경우에도 제1열매체와 제2열매체가 내관체(10)의 외주면과 외관체(20)의 외주면에서 전열되므로 전열면적이 상당히 넓게 확보되어 열매체 사이에 열교환이 한층 더 효과적으로 이루어진다. 가이드부재(30)가 스크류형태나 이중 스크루형태로 된 경우에도 제1열매체가 리싸이클되는 유로가(14) 형성되도록 구성될 수도 있다. 4 illustrates another embodiment of the present invention, in which a flow path 14 through which a first heat medium is recycled is formed at a circumference of an exterior body 20. Even in this case, since the first heat medium and the second heat medium are heat-transferred from the outer circumferential surface of the inner tube body 10 and the outer circumferential surface of the outer body 20, the heat transfer area is secured to be considerably wider, so that heat exchange is more effectively performed between the heat medium. Even when the guide member 30 is in the form of a screw or a double screw, the flow path 14 through which the first heat medium is recycled may be formed.

이상에서는 내관체(10)가 직선관으로 이루어진 것을 예로 들어 설명하였으 나, 경우에 따라서는 내관체(10)가 나선형관으로 이루어질 수도 있는데, 내관체(10)가 나선형관으로 이루어진 경우에는 내관체(10)가 직선관으로 이루어진 경우에 비해 제1열매체와 제2열매체의 전열면적이 상대적으로 더 넓게 확보되므로 열교환효율이 상승된다. In the above description, the inner tube body 10 is formed of a straight tube as an example, but in some cases, the inner tube body 10 may be formed of a spiral tube, but when the inner tube body 10 is formed of a spiral tube, the inner tube body Compared to the case where 10 is a straight tube, the heat transfer area of the first heat medium and the second heat medium is relatively wider, so that the heat exchange efficiency is increased.

이상에서와 같이 본 발명에 의하면, 고온유체와 저온유체가 이송되는 경로가 우회로를 이루도록 되어 유체들의 전열면적이 넓어짐으로써, 열교환효율이 상승되며, 이에 따라 열교환기의 전체적인 크기가 크지 않아도 소요되는 수준의 열교환효율을 얻을 수 있으므로 콤팩트한 크기를 갖는 열교환기를 제공할 수 있다.
As described above, according to the present invention, a path through which the hot fluid and the low temperature fluid are transported makes a bypass so that the heat transfer area of the fluids is widened, so that the heat exchange efficiency is increased. Since the heat exchange efficiency can be obtained, it is possible to provide a heat exchanger having a compact size.
