본 발명은 현열교환, 증발, 응축 등의 열교환작용을 위한 열교환기에 관한 것으로서, 보다 상세하게는 열교환을 위한 전열매체를 안내하는 열교환코일이 사형식으로 형성된 사형식 착탈 열교환기 및 그 제조방법에 관한 것이다.The present invention relates to a heat exchanger for heat exchange action such as sensible heat exchange, evaporation, condensation, and more particularly, to a sand-type removable heat exchanger having a heat exchange coil for guiding a heat transfer medium for heat exchange in a sand shape, and a manufacturing method thereof. will be.

열교환기는 공기, 물 등을 이용한 열교환작용에 의해 전열매체(예컨대, 냉각수, 온수, 냉매 등)를 가열 또는 냉각하기 위한 것으로서, 가정용 에어컨, 냉장고를 비롯하여 산업용 냉동기의 응축기에 사용하는 냉각용수를 재차 사용하기 위하여 냉각용수를 실외공기와 열교환시켜 냉각시키는 냉각탑 등에서 많이 사용되고 있다.The heat exchanger is for heating or cooling the heat transfer medium (e.g., cooling water, hot water, refrigerant, etc.) by heat exchange using air, water, etc., and uses the cooling water used in the condenser of the industrial refrigerator, including domestic air conditioners and refrigerators. To this end, it is widely used in cooling towers for cooling cooling water by exchanging heat with outdoor air.

이러한 열교환기는 사용용도, 용량 등에 따라 다양한 구조로 이루어지고 있으며, 특히 대용량이 요구되는 냉각탑 등에서는 다음과 같은 사형식 착탈 열교환기를 사용하고 있는 것이 현실정이다.The heat exchanger is made of various structures according to the use purpose, capacity, and the like, and in particular, in a cooling tower requiring a large capacity, it is practical to use a sand-type removable heat exchanger as follows.

도 1은 종래 기술에 따른 사형식 착탈 열교환기의 측단면도이다.1 is a side cross-sectional view of a sand type removable heat exchanger according to the prior art.

도 1에 도시된 바와 같이 종래 기술에 따른 사형식 착탈 열교환기는 전열매체를 안내하는 열교환코일(10)이 뱀처럼 구불구불한 형상으로 형성되어 프레임(20)에 의해 지지된 구성을 취한다. 사형식 착탈 열교환기의 열교환코일(10)은 압출 성형에 의해 일체로 제조되거나 용접 접합 등에 의해 하나로 연결된 긴 코일을 사형식으로 굽히는 공정에 의해 제조되고 있다.As illustrated in FIG. 1, the sand type detachable heat exchanger according to the related art has a configuration in which a heat exchange coil 10 for guiding a heat transfer medium is formed in a serpentine-like serpentine shape and supported by the frame 20. The heat exchange coil 10 of the sand type detachable heat exchanger is manufactured by a process of bending a long coil connected in one form by extrusion molding or being integrally connected by welding or the like.

그런데, 종래의 사형식 착탈 열교환기는 다음과 같은 문제점이 지적되고 있다.However, the following problems are pointed out in the conventional sand type removable heat exchanger.

열교환코일(10) 내부가 부식되면, 이로 인해 열교환코일(10) 내부에 부식층이 발생하여 열교환성능이 저하되며, 열교환코일(10)의 수명이 급격히 감소하여, 열교환코일(10)을 일정 주기로 교체해야된다. 특히, 동절기에 열교환코일(10)의 동파 방지를 위해 열교환코일(10) 내 전열매체를 배출시키는 경우, 전열매체 배출 및 재충전시 열교환코일(10)의 내부가 개방되는데, 이때 열교환코일(10)이 산소에 반응하여 열교환코일(10)의 내부가 급격히 부식할 수 있기 때문에, 열교환코일(10)의 외부는 물론 내부도 부식이 방지될 수 있어야 한다.When the inside of the heat exchange coil 10 is corroded, this causes a corrosion layer to be generated inside the heat exchange coil 10, thereby degrading the heat exchange performance, and the life of the heat exchange coil 10 is drastically reduced, thereby replacing the heat exchange coil 10 at regular intervals. Should be. In particular, when the heat transfer medium in the heat exchange coil 10 is discharged in order to prevent freezing of the heat exchange coil 10 in winter, the inside of the heat exchange coil 10 is opened when the heat transfer medium is discharged and recharged. Since the inside of the heat exchange coil 10 may be rapidly corroded in response to the oxygen, the inside and the outside of the heat exchange coil 10 should be prevented from being corroded.

따라서, 특히 냉각탑 등에 적용되는 열교환기는 대용량이기 때문에 유지보수가 용이하지 않으며 이에 따른 비용이 상당히 소요되며, 또한 하나의 열교환코일(10) 전체를 유지보수, 교체해야된다.Therefore, in particular, a heat exchanger applied to a cooling tower is not easy to maintain due to its large capacity, and thus a considerable cost is required, and one whole heat exchange coil 10 needs to be maintained and replaced.

그러데, 열교환코일(10)은 아연도금, 부식방지코팅의 파손 문제 때문에 아연도금, 부식방지코팅 후 사형식으로 제조되기 위한 용접 작업이나 굽힘 작업 등이 불가능하다. 그리고, 사형식 열교환코일(10)이 완성되고 난 후에는, 사형식 열교환코일(10)이 매우 길고 구불구불하기 때문에, 사형식 열교환코일(10)의 내부를 아연 도금하거나 부식방식 코팅하는 것이 현실적으로 불가능하다. 또한, 열교환코일(10)은 프레임(20)의 강봉(22)에 걸쳐진 상태에서 위치 고정될 수 있도록 용접 접합되기 때문에 아연도금, 부식방지코팅이 현실적으로 불가능하며, 특히 용접부분이 부식되기 쉽다. 따라서, 종래의 사형식 착탈 열교환기는 부식에 매우 취약하다.However, the heat exchange coil 10 is not possible due to the problem of galvanizing, anti-corrosion coating, welding or bending work to be manufactured in a sand form after galvanizing, anti-corrosion coating. After the sand-type heat exchange coil 10 is completed, since the sand-type heat exchange coil 10 is very long and meandering, it is practical to galvanize or corrode the inside of the sand-type heat exchange coil 10. impossible. In addition, since the heat exchange coil 10 is weld-bonded to be fixed in a position spanning the steel bar 22 of the frame 20, galvanizing and anti-corrosion coating are practically impossible, and in particular, weld parts are easily corroded. Therefore, the conventional sand type removable heat exchanger is very vulnerable to corrosion.

하여, 현실정에서는 다음과 같이 열교환코일(10)의 부식을 방지하기 위한 방안이 제시되고 있다.Thus, in reality, a method for preventing corrosion of the heat exchange coil 10 is proposed as follows.

전열매체가 유체인 수냉식인 경우, 열교환기가 여름철에만 가동되고 동절기에는 가동되지 않기 때문에, 열교환코일(10) 내부에 전열매체와 함께 에틸렌글리콜과 같은 부동액과 부식억제제를 주입하고 있다.When the heat transfer medium is a fluid-cooled liquid, the heat exchanger is operated only during the summer season and not during the winter season. Thus, an antifreeze such as ethylene glycol and a corrosion inhibitor are injected into the heat exchange coil 10 together with the heat transfer medium.

그런데, 부동액과 부식억제제 주입으로 인해 초기투자비용이 증가하며, 주기적으로 부동액과 부식억제제를 첨가해야 하므로 유지관리비도 증가하고 부동액과 부식억제제를 교체하는 경우 발생하는 폐기물에 의한 환경 훼손의 문제점이 지적되고 있다.However, the initial investment cost is increased due to the injection of antifreeze and corrosion inhibitor, and it is necessary to add antifreeze and corrosion inhibitor on a regular basis. Therefore, maintenance costs increase and the problem of environmental damage caused by waste generated when replacing antifreeze and corrosion inhibitor is pointed out. It is becoming.

또한, 비열이 적은 부동액과 부식억제제 주입하여 열교환기를 가동할 경우, 부동액과 부식억제제를 주입하지 않은 경우와 비교하여 효율이 낮아지므로, 이러한 효율저하를 보완하기 위해 열교환기를 더 큰 용량으로 설계할 수밖에 없다. 열교환기의 용량이 증가하면, 전열매체의 순환유량도 함께 증가하여 펌프 용량도 커져야 하고, 냉각팬 모터 동력도 커져야 하기 때문에, 결국 초기투자비용은 물론 운전비가 급격히 상승하는 문제점이 지적되고 있다.In addition, when the heat exchanger is operated by injecting an antifreeze and a corrosion inhibitor having a low specific heat, the efficiency is lower than that when an antifreeze and a corrosion inhibitor are not injected. Therefore, the heat exchanger has to be designed with a larger capacity to compensate for this efficiency decrease. none. As the capacity of the heat exchanger is increased, the circulation flow rate of the heat transfer medium is also increased to increase the pump capacity, and the power of the cooling fan motor must be increased. Therefore, the initial investment cost and the operating cost are rapidly increased.

그러므로 열교환코일(10)의 부식을 보다 효율적으로 방지할 수 있는 연구 방안이 절실히 요구되고 있는 실정이다.Therefore, there is an urgent need for a research method that can more effectively prevent corrosion of the heat exchange coil 10.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 내부도 아연도금, 부식방지코팅 등이 용이하게 이루어질 수 있는 사형식 착탈 열교환기 및 그 제조방법을 제공함을 그 목적으로 한다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a sand-type removable heat exchanger and a method for manufacturing the same, which can be easily galvanized, anti-corrosion coating inside.

또한, 본 발명은 상기의 사형식 착탈 열교환기의 제조방법으로서, 상기 프레임의 지지부에 의해 직선코일이 지지될 수 있도록 상기 프레임에 복수의 직선코일을 설치한 상태로 도금용액 또는 코팅용액에 담수시켜 도금/코팅작업을 실시하는 단계; 상기 도금/코팅작업 후, 상기 프레임에 설치된 직선코일에 연결코일을 끼움 결합시켜 열교환코일을 완성하는 단계를 포함하는 것을 특징으로 하는 사형식 착탈 열교환기의 제조방법을 함께 제시할 수 있다.In addition, the present invention is a manufacturing method of the sand-type removable heat exchanger, by desalination in a plating solution or a coating solution while a plurality of linear coils are installed in the frame so that the linear coil is supported by the support of the frame Performing plating / coating operations; After the plating / coating operation, it can be presented together with the manufacturing method of the sand type removable heat exchanger comprising the step of completing the heat exchange coil by fitting the coupling coil to the linear coil installed in the frame.

이상에서 살펴본 바와 같은 본 발명의 과제해결 수단에 의하면 다음과 같은 사항을 포함하는 다양한 효과를 기대할 수 있다. 다만, 본 발명이 하기와 같은 효과를 모두 발휘해야 성립되는 것은 아니다.As described above, according to the present invention, various effects including the following can be expected. However, the present invention does not necessarily achieve the following effects.

열교환코일이 직선코일과 연결코일로 분리 구성됨에 따라, 프레임에 직선코일만을 설치한 상태에서 도금, 코팅 작업을 함에 따라, 직선코일의 외주면은 물론 내주면도 충분히 용이하게 도금, 코팅될 수 있다.As the heat exchange coil is separated into a linear coil and a connecting coil, the plating and coating operations are performed in a state where only the linear coil is installed in the frame, so that the outer circumferential surface as well as the inner circumferential surface of the linear coil can be easily plated and coated.

또한, 열교환코일이 직선코일과 연결코일로 분리된 구조이며 서비스가 가능한 착탈 내식성 코일로서, 열교환코일의 분리가 용이하게 이루어질 수 있어, 열교환코일의 부분 유지보수, 교체가 가능하다. In addition, the heat exchange coil is a structure that is separated into a linear coil and a connection coil and is a removable corrosion resistant coil that can be serviced, and the separation of the heat exchange coil can be easily performed, thereby enabling partial maintenance and replacement of the heat exchange coil.

또한, 열교환코일의 직선코일과 연결코일이 상호 용접 접합 대신 끼움 결합될 수 있기 때문에, 직선코일의 도금, 코팅이 파손되는 것을 방지할 수 있다.In addition, since the linear coil and the connection coil of the heat exchange coil can be fitted instead of mutual welding, the plating and coating of the linear coil can be prevented from being damaged.

또한, 프레임의 지지부에 직선코일이 안착되는 홈 또는 홀이 형성됨에 따라 직선코일의 설치 위치가 결정될 수 있으며 직선코일의 흔들림이 방지될 수 있다.In addition, as the groove or the hole in which the linear coil is seated is formed at the support of the frame, the installation position of the linear coil may be determined, and the shaking of the linear coil may be prevented.

또한, 프레임의 지지부의 홀이 펀칭되어 돌출됨으로써 직선코일을 보다 안정적으로 지지할 수 있으며, 이 부분이 열교환코일의 진동, 충격을 흡수하는 스프링 역할을 할 수 있다. 특히, 프레임의 지지부의 돌출된 펀칭부분이 홀의 둘레방향을 따라 복수로 분리되도록 절개됨에 따라, 스프링 특성이 보다 향상될 수 있다.In addition, the hole of the support portion of the frame is punched out to protrude, so that the linear coil can be more stably supported, and this portion can serve as a spring for absorbing vibration and shock of the heat exchange coil. In particular, as the protruding punching portions of the support of the frame are cut apart in a plurality along the circumferential direction of the hole, the spring characteristics can be further improved.

또는, 프레임의 지지부의 홀과 직선코일 사이에 부시가 개재됨으로써, 부시가 스프링 역할을 할 수 있으며, 프레임과 직선코일의 소재가 다른 경우 이종 재질의 접촉으로 인한 부식 등을 방지할 수 있다.Alternatively, the bush may act as a spring between the hole and the straight coil of the support of the frame, and when the material of the frame and the straight coil is different, corrosion due to contact between dissimilar materials may be prevented.

특히, 조인트(140)는 연결코일(120)과 직선코일(110)의 끼움 결합을 용이하게 하되 충분히 기밀이 유지될 수 있도록 함과 아울러, 연결코일(120)과 직선코일(110)의 분리가 가능토록 다음과 같이 이루어지는 것을 특징으로 할 수 있다.In particular, the joint 140 facilitates the fitting coupling of the connection coil 120 and the linear coil 110 to maintain sufficient airtightness, and separates the connection coil 120 and the linear coil 110 from each other. It may be characterized as made as follows.

즉, 조인트(140)는 본체부(130)와 일체로 연결되는 몸체(142) 및, 멈춤부재(144), 반경방향 탄성부재(145), 축방향 탄성부재(146), 덮개부재(147), 씰링(148) 및 환형의 링(149)을 포함할 수 있다. 몸체(142)는 직선코일(110)을 수용하기 위한 것으로, 속이 비어 있고 내주벽을 따라 연결코일(120)의 본체부(130)의 내부통로(102)보다 직경이 큰 환형의 홈부(142a)와 경사부(142b)가 형성될 수 있다. 몸체(142)의 경사부(142b)의 직경은 연결코일(120)의 본체부(130)에서 조인트(140)를 향하는 방향을 따라, 점진적으로 확장되거나 축소될 수 있다. 멈춤부재(144)는 몸체(142)에 수용되는 직선코일(110)의 움직임을 멈추게 하기 위한 것으로, 외주면이 경사부(142b)와 대응하게 경사지게 형성되고 경사부(142b)를 따라 이동하게 된다. 멈춤부재(144)는 같은 크기의 원호 형태로 만들어지고, 안정된 구도를 갖도록 3개로 분리되어 있다. 또한, 멈춤부재(144)의 내주면에는 직선코일(110)의 진입방향으로 경사진 다수의 환형의 톱니(144a)들이 형성될 수 있다. 반경방향 탄성부재(145)는 멈춤부재(144)를 반경방향으로 탄성 지지하기 위한 것으로, 소정의 직경을 갖는 링 또는 C-링을 적용할 수 있다. 축방향 탄성부재(146)는 멈춤부재(144)를 축방향, 즉 직선코일(110)의 진입 방향 또는 반대 방향으로 탄성 지지하기 위한 것이다. 덮개부재(147)는 직선코일(110)의 끼움 가능한 내경을 갖는 링으로 형성될 수 있다. 덮개부재(147)는 후술하는 바와 같이 멈춤부재(144)를 밀어 넣기 위한 도구(160)가 몸체(142) 안에 삽입될 수 있도록, 도구 삽입홈(147a)이 형성될 수 있다.That is, the joint 140 includes a body 142 integrally connected to the main body 130, a stop member 144, a radial elastic member 145, an axial elastic member 146, and a cover member 147. , Sealing 148 and annular ring 149. The body 142 is for accommodating the straight coil 110, and has an annular groove 142a having a hollow inside and larger in diameter than the inner passage 102 of the main body 130 of the connection coil 120 along the inner circumferential wall. And the inclined portion 142b may be formed. The diameter of the inclined portion 142b of the body 142 may be gradually expanded or reduced along the direction from the body portion 130 of the connecting coil 120 toward the joint 140. The stop member 144 is to stop the movement of the linear coil 110 accommodated in the body 142, the outer peripheral surface is formed to be inclined corresponding to the inclined portion 142b and to move along the inclined portion 142b. The stop member 144 is made in the shape of an arc of the same size, and is separated into three to have a stable composition. In addition, a plurality of annular teeth 144a inclined in the direction of entry of the linear coil 110 may be formed on the inner circumferential surface of the stop member 144. The radially elastic member 145 is for elastically supporting the stop member 144 in the radial direction, and a ring having a predetermined diameter or a C-ring may be applied. The axial elastic member 146 is for elastically supporting the stop member 144 in the axial direction, that is, the entry direction or the opposite direction of the straight coil 110. The cover member 147 may be formed as a ring having a fitting inside diameter of the straight coil 110. The cover member 147 may be formed with a tool insertion groove 147a so that the tool 160 for pushing the stop member 144 may be inserted into the body 142 as described below.

이와 같은 조인트(140)에 의한 연결코일(120)과 직선코일(110)의 끼움 결합은 다음과 같이 이루어질 수 있다. The coupling coupling of the connection coil 120 and the linear coil 110 by the joint 140 may be made as follows.

도 8에 도시된 바와 같이, 도구(160)를 조인트(140)의 몸체(142) 안에 집어넣어서 도구(160)를 이용하여 조인트(140)의 멈춤부재(144)를 연결코일(120)의 내부로 밀어 넣은 후, 조인트(140)의 몸체에 직선코일(110)을 끼워 넣는다. 이때, 조인트(140)의 멈춤부재(144)가 연결코일(120)의 내부에 밀려 들어간 상태이므로, 직선코일(110)이 조인트(140)의 멈춤부재(144)에 의해 간섭받지 않고 용이하게 조인트(140)의 몸체에 끼워질 수 있다. 이와 같이 직선코일(110)이 조인트(140)의 몸체에 끼워진 후, 도구(160)를 빼면 조인트(140)의 축방향 탄성부재(146)가 탄성 복원력에 의해 조인트(140)의 멈춤부재(144)가 연결코일(120)의 외측으로 이동하여 도 6에 도시된 바와 같이 직선코일(110)에 밀착되어 직선코일(110)에 꽉 물릴 수 있다. 따라서, 연결코일(120)과 직선코일(110)이 상호 견고하게 끼움 결합될 수 있으며, 상호 간 기밀이 유지될 수 있다. As shown in FIG. 8, the tool 160 is inserted into the body 142 of the joint 140 and the stop member 144 of the joint 140 is connected to the inside of the connection coil 120 using the tool 160. After pushing in, the straight coil 110 is inserted into the body of the joint 140. At this time, since the stop member 144 of the joint 140 is pushed into the connection coil 120, the straight coil 110 is easily joined without being interrupted by the stop member 144 of the joint 140. It can be fitted to the body of (140). After the linear coil 110 is inserted into the body of the joint 140 in this manner, the tool 160 is removed and the axial elastic member 146 of the joint 140 stops the member 144 of the joint 140 by the elastic restoring force. ) Moves to the outside of the connection coil 120 to be in close contact with the linear coil 110 as shown in Figure 6 may be tightly bitten by the linear coil (110). Therefore, the connection coil 120 and the linear coil 110 may be firmly fitted to each other, the mutual airtightness can be maintained.

연결코일(120)을 직선코일(110)로부터 분리할 때에는, 도 8에 도시된 바와 같이 조인트(140)의 덮개부재(147)의 도구 삽입홈(147a)을 통해 도구(160)를 조인트(140)의 몸체(142) 안에 넣어서 조인트(140)의 멈춤부재(144)를 연결코일(120)의 내부로 밀어 넣는다. 그러면, 조인트(140)의 멈춤부재(144)가 직선코일(110)로부터 이격됨으로써, 조인트(140)의 멈춤부재(144)에 의한 직선코일(110)의 물림이 해제되어 직선코일(110)이 연결코일(120)로부터 빠질 수 있다.When the connecting coil 120 is separated from the straight coil 110, the tool 160 is connected to the joint 140 through the tool insertion groove 147a of the cover member 147 of the joint 140, as shown in FIG. 8. The stop member 144 of the joint 140 is pushed into the connection coil 120 by putting it into the body 142. Then, the stop member 144 of the joint 140 is spaced apart from the straight coil 110, thereby the bite of the straight coil 110 by the stop member 144 of the joint 140 is released, so that the straight coil 110 is The connection coil 120 may be pulled out.

한편, 연결코일(120)은 어떠한 형상을 취하든 무방하나, 다만 전열매체의 유동 저항을 최소화할 수 있도록 도시된 바와 같이 말굽모양으로 구부러진 형상으로 이루어지는 것이 보다 유리할 수 있다.On the other hand, the connecting coil 120 may take any shape, but it may be more advantageous to be formed in a shape bent in the shape of a horseshoe as shown so as to minimize the flow resistance of the heat transfer medium.

프레임(200)은 열교환코일(100)이 내부에 설치될 수 있도록 테두리를 형성하는 테두리 형성부(210) 및, 테두리 형성부(210)에 의해 형성되는 테두리 안에 설치되는 열교환코일(100)을 지지하는 지지부(220)를 포함할 수 있다.The frame 200 supports the edge forming portion 210 that forms the edge so that the heat exchange coil 100 can be installed therein, and the heat exchange coil 100 installed in the edge formed by the edge forming portion 210. It may include a support 220.

프레임(200)의 테두리 형성부(210)는 도시된 바와 같이 육면체 구조를 형성토록 이루어질 수 있으며, 이외에도 다양한 구조를 형성토록 이루어질 수 있다.The edge forming part 210 of the frame 200 may be formed to form a hexahedral structure as shown, and may be formed to form various structures in addition to the above.

프레임(200)의 지지부(220)는 직선코일(110)을 안정적으로 지지할 수 있도록 직선코일(110)의 길이방향을 따라 복수 구성되는 것이 보다 유리할 수 있다. 특히, 프레임(200)의 지지부(220)는 도시된 바와 같이 적어도 직선코일(110)의 길이방향을 따라 직선코일(110)의 양단을 각각 지지토록 구성되는 것이 바람직할 수 있다. 아울러, 직선코일(110)의 길이가 긴 경우, 플임의 지지부(220)는 도시된 바와 같이 직선코일(110)의 길이방향을 따라 직선코일(110)의 중간부분을 지지토록 하나 또는 둘 이상 더 추가될 수 있다.The support unit 220 of the frame 200 may be more advantageously configured in the longitudinal direction of the linear coil 110 so as to stably support the linear coil 110. In particular, the support 220 of the frame 200 may be configured to support both ends of the linear coil 110 at least along the longitudinal direction of the linear coil 110 as shown. In addition, when the length of the straight coil 110 is long, the support portion 220 of the fleece is one or two or more to support the middle portion of the straight coil 110 along the longitudinal direction of the straight coil 110 as shown Can be added.

지지부(220)는 테두리 형성부(210)에 용접 접합 등에 의해 영구적으로 고정될 수도 있고, 볼트 체결이나 슬라이드 끼움 방식 등에 의해 테두리 형성부(210)에 탈부착 가능토록 결합될 수 있다.The support unit 220 may be permanently fixed to the edge forming unit 210 by welding or the like, or may be coupled to the edge forming unit 210 so as to be detachable by a bolt fastening or a slide fitting method.

지지부(220)는 단지 직선코일(110)을 받칠 수도 있으나, 도시된 바와 같이 직선코일(110)이 안착되는 홈(222) 또는 홀(224)이 형성될 수 있다. 이 경우, 지지부(220)의 홈(222) 또는 홀(224)에 직선코일(110)이 안착됨에 따라, 지지부(220)에 의해 각각의 직선코일(110)의 설치가 안내되어 위치 결정될 수 있기 때문에 직선코일(110)의 흔들림이 방지될 수 있으며 직선코일(110) 간 배열이 유지될 수 있다. The support 220 may only support the linear coil 110, but as shown, a groove 222 or a hole 224 in which the linear coil 110 is seated may be formed. In this case, as the linear coil 110 is seated in the groove 222 or the hole 224 of the support 220, the installation of each linear coil 110 may be guided and positioned by the support 220. Because of this, shaking of the linear coil 110 can be prevented and the arrangement between the linear coils 110 can be maintained.

이와 같은 지지부(220)는 특히 도 9 내지 도 13, 도 15에 도시된 바와 같이, 홀(224)이 복수 형성된 플레이트(220A)로 이루어질 수 있다. 이 경우, 도시된 바와 같이 지지부(220)는 모든 직선코일(110)의 안착이 가능토록 테두리 형성부(210)의 일면을 복개하거나 구획할 수 있는 크기의 플레이트(220A)로 이루어질 수 있다. In particular, as shown in FIGS. 9 to 13 and 15, the support 220 may be formed of a plate 220A having a plurality of holes 224 formed therein. In this case, as shown, the support 220 may be formed of a plate 220A of a size that can cover or partition one surface of the edge forming portion 210 so that all the linear coils 110 can be seated.

이와 아울러, 도 11 및 도 12에 도시된 바와 같이, 지지부(220)의 홀(224)은 직선코일(110)이 끼워지는 방향으로 플레이트(220A)를 펀칭하여 이 펀칭부분(226)이 돌출되도록 하여 이루어질 수 있다. 이 경우, 지지부(220)의 돌출된 펀칭부분(226)으로 인해 직선코일(110)이 보다 안정적으로 지지될 수 있으며, 플레이트(220A)가 알루미늄이나 플라스틱과 같은 강성이 크지 않은 소재에 의해 얇은 두께로 형성된 경우 지지부(220)의 돌출된 펀칭부분(226)이 판 스프링과 같은 역할을 할 수 있어 열교환코일(100)에 발생된 진동이나 충격을 흡수해질 수 있다. 나아가, 도 12에 도시된 바와 같이, 지지부(220)의 돌출된 펀칭부분(226)은 지지부(220)의 홀(224)의 둘레를 따라 복수로 절개(228)될 수 있으며, 이에 따라 스프링 특성이 강화될 수 있고, 지지부(220)의 돌출된 펀칭부분(226)이 벌어질 수 있어 직선코일(110)이 용이하게 끼워질 수 있고, 지지부(220)의 돌출된 펀칭부분(226)이 직선코일(110)에 밀착되어 직선코일(110)이 보다 안정적으로 지지될 수 있다.In addition, as shown in FIGS. 11 and 12, the hole 224 of the support part 220 punches the plate 220A in the direction in which the linear coil 110 is fitted so that the punching part 226 protrudes. It can be done by.
