본 발명은 다양한 형태의 유체흐름 요구를 갖는 열교환기용 전열판을 다수개 횡적시킬때 이용되는 가스켓에 관한 발명이다.The present invention relates to a gasket used for transversing a plurality of heat exchanger plates for heat exchangers having various types of fluid flow requirements.

열교환기를 구성함에 있어서 유체흐름 요구를 갖는 전열판을 횡적시키는 것은 필수적으로 각 전열판이 횡적되어 이루어지는 물흐름 요구를 폐쇄시키기 위해서 각 전열판 사이에 탄성을 갖는 고무종류의 가스켓이 삽지되며, 전열판에는 가스켓 삽지요구가 요설되는 것이다.In the construction of the heat exchanger, it is essential to horizontally heat the heat transfer plate having a fluid flow demand, and a rubber-type gasket is inserted between each heat transfer plate to close the water flow demand formed by the heat transfer plate, and a gasket insert is inserted into the heat transfer plate. Is to be argued.

이 가스켓은 전열판이 횡적 연결이전에 요구에 삽지시켜야 하며 횡적 조립작업 과정에서 가스켓이 전열판에 안정되게 부착되어 있어야 만이 안전하게 조립될 수 있으며 만약 가스켓이 전열판의 가스켓 홈에서 이탈되거나 유동이 생기게 되면 유체가 유출되는 원인이 되는 것이다.The gasket must be inserted on demand before the lateral connection, and the gasket can be safely assembled only when the gasket is securely attached to the plate during the lateral assembly process.If the gasket is released from the gasket groove of the plate or fluid is generated, It is the cause of leakage.

그러므로 가스켓은 전열판을 이동하거나 상당한 유동과 외부충격을 받더라도 홈에서 이탈되는 폐단이 없어야 하며 가스켓과 홈이 항시 긴밀한 상태를 유지해야 만이 가스켓과 홈사이에 공간이 생기지 않게 되어 이탈방지나 이물질 침입을 막을 수가 있게 되는 것이다.Therefore, even if the gasket moves or is subjected to considerable flow and external shock, there should be no closed end from the groove, and the gasket and groove should be kept in close contact at all times so that no space is created between the gasket and the groove to prevent separation or foreign matter intrusion. It becomes the number.

가스켓이 전열판의 홈에서 이탈되는 것을 방지하기 위한 수단으로 종래 알려지고 있는 가스켓의 부착방법으로는 접착제를 이용하는 것과 가스켓 자체의 구조를 개량한 것들이 알려지고 있는 것으로 통상 이용되고 있는 손쉬운 방법으로는 가스켓에 접착제를 도포하여 홈에 접착시키는 것으로 이와 같은 방법은 접착제를 도포시키는 작업과정이 복잡하고 먼지 등의 물질이 접착제에 부착되어 밀착도를 저하시키게 되고 접착제의 도포량이 과다하였을 때는 홈밖으로 흘러 나오게 되어 있어어 청결치 못한 문제점이 있게 되고 가스켓을 교체시에는 전열판에 부착된 접착제를 제거하는데 많은 시간이 소요되는 등의 문제점이 있게 되는 것이다.As a means for preventing the gasket from detaching from the grooves of the heat transfer plate, conventionally known methods of attaching the gasket include those using an adhesive and improving the structure of the gasket itself. In this method, the process of applying the adhesive is complicated and materials such as dust are attached to the adhesive to reduce the adhesion. When the amount of the adhesive is excessively applied, it flows out of the groove. There is a problem that is not clean and when replacing the gasket there is a problem such as a large amount of time to remove the adhesive attached to the heat transfer plate.

또한 가스켓을 착설키 위한 구조를 개량한 것으로 전열판의 연부 수 개소에 구멍을 천공하여 가스켓에서 일체로 연장 성형된 취착편의 돌기를 구멍에 끼워 넣어 고정시키는 것이 있으나 전열판에 구멍을 천공하는 작업이 복잡하고 가스켓에 취착편과 돌기를 성형키 위한 금형제작과 재료낭비 등으로 제작원가의 상승요인이 됐으며, 좀 더 개량된 가스켓의 구조로 국내 특허공보 제2293호 공번 91-3072호에 개재된 "열교환기판용 가스켓 장치"가 알려지고 있으나 이 선행 발명에서는 가스켓(1)의 외측면에 돌출부(2) (3) (4)와 연결부(2A)를 갖는 취착편을 일체로 구성하여 돌출부(3) (4)가 전열판의 주연부에 형성되는 파상형의 요구에 끼워지게 하여 가스켓이 이탈되는 것을 방지할 수 있게 된 것이 알려지고 있으나, 이와 같은 장치는 전열판 연부에 요설된 요구에 끼워지는 돌출부(2) (3)에 의해 가스켓이 지지됨으로 가스켓 본체가 가스켓 홈에 긴밀하게 밀착되는 효과는 얻지 못하며 전열판을 상호 접합시키는 과정에서 약간의 유동에도 가스켓이 요구에서 이탈되는 폐단이 있으며 이와 같은 복잡한 구조의 가스켓을 얻기 위해서는 금형제작 등이 더욱 어려워지는 문제점이 있게 되는 것이다.In addition, the structure to install the gasket has been improved. Some holes are drilled at the edges of the heating plate, and the projections of the fitting pieces that are integrally formed from the gasket are inserted into the holes to fix the gaskets. The manufacturing cost was increased due to the manufacture of mold and material wasted to form gaskets and protrusions on the gasket, and the heat exchanger board disclosed in Korean Patent Publication No. 2293 No. 91-3072 due to the improved gasket structure. Is known in the art, but in this prior invention, a fitting piece having protrusions 2, 3, 4 and a connecting portion 2A is integrally formed on the outer surface of the gasket 1 so that the protrusions 3, 4 It is known that it is possible to prevent the gasket from being detached by fitting a) to the wave-shaped request formed at the periphery of the heat transfer plate, but such a device is required for the heat transfer plate edge. Since the gasket is supported by the fitting protrusions (2) and (3), the gasket main body is not in close contact with the gasket groove, and there is a closed end in which the gasket is released from the demand even with a slight flow in the process of joining the heating plates. In order to obtain a gasket of the same complicated structure, the manufacturing of the mold becomes more difficult.

또한 일본공개 실용신안공보 공개번호 평2-127960호로 가스켓의 끼움구조가 알려지고 있으나 상기 국내 특허공보에 개재된 선행기술와 유사하여 전열판의 홈측면에 홈과 연통되는 가스켓 끼움구를 형성하고 끼움구 저면에 구멍을 천공하여 가스켓의 돌기가 구멍에 끼워지게 한 것이 알려지고 있으나 가스켓 본체를 안전하게 지지시킬 수 는 없는 것이다.In addition, although the fitting structure of the gasket is known as Japanese Patent Application Laid-open No. Hei 2-127960, it is similar to the prior art disclosed in the domestic patent publication, forming a gasket fitting hole communicating with the groove on the groove side of the heat transfer plate and the bottom of the fitting hole. It is known that the gasket protrusion is inserted into the hole by drilling a hole in the gasket, but the gasket body cannot be securely supported.

본 발명은 상기 제반 문제점을 해결하기 위하여 전열판의 가스켓 삽지홈과 가스켓이 보다 긴밀하고도 견고하게 밀착될 수 있는 가스켓을 발명하게 된 것으로 이하 첨부도면에 의거하여 본 발명의 구조 및 작용효과를 설명하면 다음과 같다.In order to solve the above problems, the gasket insertion groove and the gasket of the heat transfer plate have been invented, and the gasket can be tightly and firmly adhered to. As follows.

내측으로 물흐름요구(21)와 외측연부에 파상형 요철부(22) (23)가 형성된 전열판(20)의 가스켓 삽지홈(24)에 취착편(26)이 돌설된 공지의 가스켓(25)을 삽지시키는 것에 있어서 가스켓(25)의 저면 수 개소와 취착편(26)의 저면에 일체로 흡착돌륜(30) 및 흡착돌륜(40)을 돌설하여 흡착부(31) 및 흡착부(41)가 형성되게 한 것이다.Known gasket 25 in which the fitting piece 26 is protruded into the gasket insertion groove 24 of the heat transfer plate 20 in which the water flow demand 21 and the wave-shaped concave-convex portions 22 and 23 are formed in the outer edge thereof. Is inserted into the bottom surface of the gasket 25 and the bottom surface of the fitting piece 26, the suction protrusion wheel 30 and the suction protrusion wheel 40 are integrally formed so that the suction part 31 and the suction part 41 It was formed.

이와 같이 된 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention as described above are as follows.

가스켓(25)은 가스켓 삽지홈(24)에 취착편(26)은 파상형 요부(22)에 삽지시켜 눌러주면 가스켓(25)과 취착편(26)의 저면에 형성된 흡착돌륜(30) 및 흡착돌륜(40)이 가스켓 삽지홈(24)의 내저면과 파상형 요부(22)의 내저면에 흡착상태로 긴밀하고 견고하게 밀착되는 것이다.The gasket 25 is inserted into the gasket insertion groove 24, and the fitting piece 26 is inserted into the corrugated recess 22 to press the suction protrusion wheel 30 formed on the bottom surface of the gasket 25 and the fitting piece 26. The wheel wheel 40 is in close contact with the inner bottom of the gasket insertion groove 24 and the inner bottom of the corrugated recess 22 in a state of being adsorbed tightly and firmly.

흡착력은 돌륜(30)의 내면적과 비례하는 것으로 수 개소에 형성되는 흡착부(31) 및 (41)의 흡착력에 의해 가스켓(25)과 취착편(26)이 전열판(20)의 가스켓 삽지홈(24)과 파상형 요부(22)에 밀착되어 이탈되는 폐단이 없게 되고 가스켓(25)의 밀착도가 높게 됨으로 이물질의 침입을 방지할 수가 있게 되는 것이다.The adsorption force is proportional to the inner area of the wheel wheel 30, and the gasket 25 and the fitting piece 26 are connected to the gasket insertion groove of the heat transfer plate 20 by the adsorption force of the adsorption portions 31 and 41 formed at several places. 24) and the corrugated recess 22, there is no closed end to be separated and the adhesion of the gasket 25 is high to prevent the intrusion of foreign matter.

이상과 같이 본 발명은 가스켓과 일체로 흡착부가 형성되고 그 구조가 매우 간단하여 가스켓 제작이 용이하며 아울러 착설시키는 작업이 손쉬웁고 견고하며 긴밀하게 착설되는 잇점과 가스켓 교환작업이 쉽고 전열판을 깨끗하게 유지할 수가 있게 되는 것이다.As described above, the present invention has an adsorption unit formed integrally with the gasket, and its structure is very simple, so that the gasket is easy to manufacture, and the installation work is easy, robust, and closely installed. Will be.
