Description

열 교환기{Heat Exchanger}Heat Exchanger

본 발명은 열 교환기에 관한 것으로, 특히 신규한 고정 방식의 나선형 핀 열 교환기에 관한 것이다.The present invention relates to a heat exchanger and in particular to a novel fixed type helical fin heat exchanger.

냉장고, 아이스박스 등의 냉장 장치에 사용되는 열 교환기는 대부분 나선형 핀 열 교환기, 즉 핀 튜브를 사용하여 열 교환을 달성하는 열 교환기이다. 핀 튜브는 주로 내측 튜브와 내측 튜브의 표면에 구비되는 다수의 핀을 포함한다. 현재의 시장에서, 핀 튜브 구조를 갖는 그러한 방열기(radiator)는 일반적으로 금속 스트랩을 감아서 고정한다. 금속 스트랩은 주름 형태 또는 시트 플랜징(sheet flanging) 형태로 핀 튜브 상에 감기거나 용접됨으로써, 열 교환기의 방열 면적 및 방열 효과가 향상될 수 있어서, 에너지 절감 효과를 달성할 수 있다.  Heat exchangers used in refrigerators, such as refrigerators and iceboxes, are mostly spiral fin heat exchangers, ie heat exchangers that achieve heat exchange using fin tubes. The fin tube mainly includes an inner tube and a plurality of fins provided on the surface of the inner tube. In the current market, such radiators having a fin tube structure are generally wound around a metal strap to secure it. The metal strap is wound or welded onto the fin tube in the form of a corrugation or sheet flanging, whereby the heat dissipation area and the heat dissipation effect of the heat exchanger can be improved, thereby achieving an energy saving effect.

그러나, 열 교환기의 그러한 고정 구조에 있어서의 금속 스트랩은 일반적으로 열 교환기의 핀 상에 감기며, 일반적으로 죔쇠에 의해 그 둘레가 고정될 수 있을 뿐이다. 결과적으로, 죔쇠와 핀 튜브 간의 접촉은 거의 이루어지지 않아서 안정된 고정을 달성하지 못한다. 실제로 사용될 경우, 열 교환기는 압축기로 인하여 진동을 일으키기 때문에, 핀 튜브가 쉽게 느슨해져서 소음이 발생하기 쉽고, 따라서 전체 냉장 장치의 품질에 악영향을 미치게 된다.However, the metal straps in such a fixing structure of the heat exchanger are generally wound on the fins of the heat exchanger and can generally only be secured around them by the clamps. As a result, the contact between the clamp and the pin tube is hardly achieved and thus does not achieve stable fixation. When used in practice, the heat exchanger causes vibrations due to the compressor, so that the fin tube is easily loosened and noise is likely to occur, thus adversely affecting the quality of the entire refrigeration unit.

한편, 열 교환기의 열 교환 면적 및 에너지 소모와 관련된 요건을 충족시키기 위해서, 핀 튜브는 일반적으로 반복적으로 절곡되어 제조된다. 제품의 특성상, 절곡 내부 링이 쉽게 풀려버리는 등의 문제가 야기될 수 있고, 이로 인해 공기 저항 및 소음이 증가하게 된다. On the other hand, in order to meet the requirements relating to the heat exchange area and energy consumption of the heat exchanger, the fin tube is generally bent and manufactured repeatedly. Due to the nature of the product, problems such as easy release of the bent inner ring can be caused, resulting in increased air resistance and noise.

본 발명은 상기한 종래 기술의 문제점을 감안하여 안출한 것으로서, 핀 튜브가 더욱 효과적으로 고정되는 열 교환기를 제공하는 것을 목적으로 한다.The present invention has been made in view of the above problems of the prior art, and an object thereof is to provide a heat exchanger in which a fin tube is more effectively fixed.

상기한 기술적인 문제점을 해결하기 위하여, 본 발명은 다음과 같은 기술적인 해결 수단을 채용한다.In order to solve the above technical problem, the present invention employs the following technical solution.

신규한 고정 방식의 나선형 핀 열 교환기는 상부에 다수의 핀이 구비된 내측 튜브를 포함하는 굴곡 핀 튜브를 포함하여 구성되며, 다수의 고정 부재가 핀 튜브 상에 구비되고, 고정 부재는 상부 브래킷과 하부 브래킷을 포함하고, 상부 브래킷은 커버 플레이트와 수직 플레이트를 포함하고, 상부 브래킷은 하부 브래킷에 고정 상태로 연결되고, 핀 튜브 상의 다수의 핀은 커버 플레이트와 하부 브래킷 사이에 배치되고, 수직 플레이트 상에는 위치 결정 홈이 구비되고, 핀 튜브의 내측 튜브는 위치 결정 홈 내에 배치된다.The novel fastening helical fin heat exchanger comprises a bent fin tube comprising an inner tube with a plurality of fins on top, wherein a plurality of fastening members are provided on the fin tubes, and the fastening members are provided with the upper bracket. A lower bracket, the upper bracket includes a cover plate and a vertical plate, the upper bracket is fixedly connected to the lower bracket, and a plurality of pins on the fin tube are disposed between the cover plate and the lower bracket, and on the vertical plate A positioning groove is provided, and the inner tube of the fin tube is disposed in the positioning groove.

핀 튜브는 반복적으로 절곡될 수 있고, 핀 튜브의 인접한 두 절곡부의 길이는 서로 다를 수 있다.The fin tube may be bent repeatedly, and the lengths of two adjacent bent portions of the fin tube may be different from each other.

상부 브래킷은 측면 브래킷을 통해 하부 브래킷에 고정 상태로 연결될 수 있다.The upper bracket can be fixedly connected to the lower bracket via the side bracket.

본 발명의 상기한 바와 같은 기술적인 해결 수단은 다음과 같은 효과를 갖는다. 나선형 핀 열 교환기는 고정 부재의 상부 및 하부 브래킷을 통해 핀 튜브의 내측 튜브와 다수의 핀을 동시에 고정할 수 있어서, 이중 고정 효과를 달성한다. 따라서, 핀 튜브가 더욱 확고히 고정될 수 있고 쉽게 풀리지 않으며, 나선형 핀 열 교환기의 소음을 효과적으로 감소시킬 수 있다.The technical solution as described above of the present invention has the following effects. The helical fin heat exchanger can simultaneously fix the inner tube of the fin tube and the plurality of fins through the upper and lower brackets of the fastening member, thus achieving a double fastening effect. Thus, the fin tube can be fixed more firmly, not easily loosened, and the noise of the helical fin heat exchanger can be effectively reduced.
