본 발명은 자동차의 배기매니폴드에 발산하는 열을 차단하는 히트 프로텍터에 관한 것으로, 특히 실린더 헤드에 볼트로 체결되면서 촉매 프로텍터에는 끼움식으로 결합되어 내구성의 향상과 원가절감을 도모하는 히트 프로텍터에 관한 것이다.The present invention relates to a heat protector for blocking heat radiating to the exhaust manifold of an automobile, and more particularly, to a heat protector that is fastened to the cylinder head by a bolt and fitted to the catalyst protector to improve durability and reduce cost. will be.

일반적으로 배기매니폴드에는 고온의 배기가스가 유동하기 때문에 배기매니폴드를 통한 열 발산량이 많고, 배기매니폴드를 통해 발산되는 고온의 열이 주변 부품으로 전도되는 것을 저감시키기 위해 히트 프로텍터가 배기매니폴드에 설치되고 있다.In general, the exhaust manifold has a large amount of heat dissipation through the exhaust manifold because hot exhaust gas flows, and the heat protector includes a heat protector to reduce the high temperature heat dissipated through the exhaust manifold. Is being installed on.

종래에는 상기 히트 프로텍터가 배기매니폴드에 설치될 때에 크랙을 방지하기 위해서 다수개의 와이어 메시와 체결볼트를 매개로 체결됨에 따라 배기매니폴드의 고열에 의한 부식이 발생할 뿐만 아니라 원가 절감에 불리하게 작용하는 문제점이 있었다.Conventionally, since the heat protector is fastened through a plurality of wire meshes and fastening bolts to prevent cracks when the heat protector is installed in the exhaust manifold, corrosion of the exhaust manifold due to high heat may be adversely affected. There was a problem.

다른 설치방식으로는 배기매니폴드에 슬롯을 3개 가공하고, 상기 슬롯에 히트 프로텍터를 삽입한 후에 일 부위에 와셔를 이용하여 볼트로 체결함에 따라 배기매니폴드의 고열에 의한 부식 발생과 배기매니폴드에 슬롯을 가공함으로 인한 제조원가의 상승 히트 프로텍터의 상하 진동 발생 등의 문제점이 있었다.In another installation method, three slots are processed in the exhaust manifold, and after the heat protector is inserted into the slot, the bolts are fastened by using a washer in one portion to cause corrosion and exhaust manifold due to the high temperature of the exhaust manifold. There was a problem such as the up and down vibration of the heat protector to increase the manufacturing cost by processing the slot.

이에 본 발명은 상기와 같은 사정을 감안하여 안출된 것으로, 고열을 발생시키는 배기매니폴드에 직접 체결하지 않고 열 피로가 적은 실린더 헤드 부위에 체결하여 크랙의 발생을 예방하고, 와이어 메시를 사용하지 않아도 될 뿐만 아니라 체결볼트의 사용 개수도 줄여서 원가 절감을 도모할 수 있는 히트 프로텍터를 제공함에 그 목적이 있다.Accordingly, the present invention has been devised in view of the above circumstances, and it is not directly fastened to the exhaust manifold that generates high heat, but is fastened to the cylinder head portion having low thermal fatigue to prevent the occurrence of cracks, and without using a wire mesh. In addition, the purpose of the present invention is to provide a heat protector that can reduce the number of fastening bolts and reduce costs.

상기와 같은 목적을 달성하기 위한 본 발명은, 실린더 헤드에 체결볼트를 끼 워서 체결할 수 있도록 형성된 다수개의 체결 보스와, 촉매 프로텍터에 형성된 다수개의 끼움구멍에 결합되게 다단으로 형성된 웨이브를 구비하고 있다.The present invention for achieving the above object is provided with a plurality of fastening bosses formed to fasten the fastening bolt to the cylinder head, and a wave formed in multiple stages to be coupled to a plurality of fitting holes formed in the catalyst protector. .

바람직하기로는, 상기 웨이브가 연속된 3단으로 형성되면서 상기 촉매 프로텍터의 내측면에 밀착되는 제1웨이브와. 상기 촉매 프로텍터의 외측면에 밀착되는 제2웨이브 및, 촉매 프로텍터의 외측면과 이격되게 배치되는 제3웨이브를 구비한 것을 특징으로 한다.Preferably, the first wave is in close contact with the inner surface of the catalyst protector while the wave is formed in three consecutive stages. And a second wave that is in close contact with the outer surface of the catalyst protector, and a third wave that is spaced apart from the outer surface of the catalyst protector.

이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1에는 본 발명에 따른 히트 프로텍터가 촉매 프로텍터와 결합된 상태의 사시도가 도시되어 있는 바, 히트 프로텍터 바디(1)의 상면 일측에는 폭 방향으로 소정 간격을 두고 2개의 체결 보스(2)가 각각 형성되어, 상기 체결 보스(2)에 도시되지 않은 체결볼트를 끼워서 열 발산량이 배기매니폴드보다 상대적으로 적은 실린더 헤드에 체결하게 되어 있으므로, 배기매니폴드의 고열 전도에 의한 히트 프로텍터의 부식과 크랙 발생을 예방하고, 내진성도 도모할 수 있게 된다.1 shows a perspective view of a heat protector according to the present invention coupled with a catalyst protector, wherein two fastening bosses 2 are provided on one side of the upper surface of the heat protector body 1 at predetermined intervals in the width direction. It is formed, and the fastening bolt (not shown) to the fastening boss (2) is fastened to the cylinder head relatively less heat dissipation than the exhaust manifold, so that the heat protector corrosion and cracks caused by high thermal conduction of the exhaust manifold It is possible to prevent and to be earthquake-resistant.

상기 히트 프로텍터 바디(1)의 하부는 촉매 프로텍터(3)와 끼움 방식으로 간단하게 결합되는 데, 즉 도 2 내지 도 5에 도시된 바와 같이 히트 프로텍터 바디의 하단면에는 3단으로 웨이브(4a,4b,4c)가 형성되어 있고, 상기 촉매 프로텍터(3)에는 상기 웨이브의 일측이 관통해서 끼워지는 2개의 끼움구멍(5)이 원주 방향으로 소정 간격을 두고 형성되어 있다.The lower portion of the heat protector body 1 is simply coupled to the catalyst protector 3 in a fitting manner, that is, as shown in FIGS. 2 to 5, the wave 4a, 4b and 4c are formed, and two said insertion holes 5 through which one side of the wave penetrates are formed in the catalyst protector 3 at predetermined intervals in the circumferential direction.

즉, 상기 웨이브가 3단으로 형성될 때에 제1웨이브(4a)는 내측에 위치하는 반면에 제3웨이브(4c)는 외측에 위치함과 더불어 제2웨이브(4b)는 중간에 위치하여 제1,2웨이브를 연속되게 연결하는 구조로 되어 있다.That is, when the wave is formed in three stages, the first wave 4a is located inside, while the third wave 4c is located outside, and the second wave 4b is located in the middle. It is structured to connect 2 waves continuously.

또한, 상기 제1웨이브는 하나로 형성되는 반면에 제1웨이브를 기준으로 제2,3웨이브는 각각 대칭되게 2개씩 형성되어 있다.In addition, the first wave is formed as one, while the second wave and the third wave are formed symmetrically with respect to the first wave.

그리고 상기 웨이브가 상기 끼움구멍에 결합될 때에 제1웨이브와 제2웨이브 사이의 절곡부위가 상기 끼움구멍(5)을 관통해서 통과하는 구조로 되어, 상기 제1웨이브(4a)는 촉매 프로텍터의 내측면에 밀착되는 반면에 제2웨이브(4b)는 촉매 프로텍터의 외측면에 밀착되게 되며, 제3웨이브(4c)는 촉매 프로텍터의 외측면과 소정 갭을 두고 이격되게 된다.When the wave is coupled to the fitting hole, the bent portion between the first wave and the second wave passes through the fitting hole 5, and the first wave 4a is formed inside the catalyst protector. While the second wave 4b is in close contact with the side surface of the catalyst protector, the second wave 4b is spaced apart from the outer surface of the catalyst protector with a predetermined gap.

상기와 같이 제1웨이브가 촉매 프로텍터의 내측면과 밀착하면서 제2웨이브는 촉매 프로텍터의 외측면과 밀착되게 결합됨에 따라 촉매 프로텍터와 히트 프로텍터가 견고한 일체를 형성하여 진동 및 소음 발생이 현저하게 줄어들게 된다.As the first wave is in close contact with the inner surface of the catalyst protector as described above, the second wave is tightly coupled with the outer surface of the catalyst protector, thereby forming a solid unit with the catalyst protector and the heat protector to significantly reduce vibration and noise generation. .

이상 설명한 바와 같이 본 발명에 따른 히트 프로텍터에 의하면, 고열을 발산하는 배기매니폴드에 직접 체결하지 않고 상대적으로 열 발산량이 적은 실린더 헤드에 체결하는 보스를 구비함에 따라 배기매니폴드의 고열에 의한 부식과 크랙의 발생을 예방할 수 있고, 실린더 헤드에 체결할 때에 별도의 와이어 메시를 사용하지 않아도 되므로 중량 및 원가 절감을 도모할 수 있으며, 촉매 프로텍터와의 간단한 끼움방식으로 견고히 결합됨에 따라 작업성의 향상과 진동 및 소음 발생을 저감시킬 수 있는 등의 효과가 있게 된다.As described above, according to the heat protector according to the present invention, since the boss is fastened to the cylinder head having a relatively low heat dissipation amount rather than being directly fastened to the exhaust manifold that emits high heat, It is possible to prevent the occurrence of cracks and to save weight and cost by not having to use a separate wire mesh when fastening to the cylinder head, and to improve workability and vibration as it is firmly combined with a simple fitting method with a catalyst protector. And noise can be reduced.
