The present invention relates to a coupling structure of a heat protector for preventing thermal degradation of an engine room to prevent convective heat from being transmitted to the engine room by heating the exhaust manifold.

일반적으로 차량 엔진의 배기 매니폴드는 엔진의 각 실린더로부터 배출되는 배기가스가 한 곳으로 모이는 관으로서, 이 배기 매니폴드를 통과하는 배기가스는 대략 600 ~ 900℃ 정도로 상당히 고온이며, 배기파이프 및 소음기 등을 거쳐 외부로 방출된다.In general, the exhaust manifold of a vehicle engine is a pipe in which exhaust gas discharged from each cylinder of the engine is gathered in one place, and the exhaust gas passing through the exhaust manifold is extremely high at approximately 600 to 900 ° C., and the exhaust pipe and silencer are It is emitted to the outside via the back.

이러한 배기 매니폴드의 외측에 장착되는 히트 프로텍터(Heat Protector)는 엔진 운전시에 고온으로 뜨거워진 배기 매니폴드의 주위 부품에 열적 손상을 가하는 것을 방지하기 위한 보호 덮개이다.The heat protector mounted on the outside of the exhaust manifold is a protective cover for preventing thermal damage to surrounding parts of the exhaust manifold heated to a high temperature during engine operation.

도 3은 상기한 바와 같은 히트 프로텍터가 배기 매니폴드의 외측에 장착된 상태의 도면으로서, 엔진(10)의 일측에는 배기 매니폴드(11)가 형성되고, 상기 배기 매니폴드(11)의 외측을 히트 프로텍터(12)가 감싸게 된다. 그리고 엔진(10)의 상측으로는 점화코일 호스(13), OTS센서(14), TPS센서(15) 등과 같은 각종 센서 및 호스들의 부품들이 배열되어 있다.3 is a view in which the heat protector as described above is mounted outside the exhaust manifold. An exhaust manifold 11 is formed at one side of the engine 10, and the outer side of the exhaust manifold 11 is formed. The heat protector 12 is wrapped. The upper part of the engine 10 includes components of various sensors and hoses such as an ignition coil hose 13, an OTS sensor 14, a TPS sensor 15, and the like.

그런데 상기한 히트 프로텍터(12)의 끝단은 실린더헤드(16)의 외측면으로부터 보통 7 ~ 12mm 정도의 간격(G)이 유지된 채 장착된다.By the way, the end of the heat protector 12 is mounted from the outer surface of the cylinder head 16 while maintaining the interval (G) of about 7 ~ 12mm.

따라서 종래기술의 경우에는 히트 프로텍터의 끝단과 실린더헤드의 측면 사이에 마련되는 갭을 통해서 200℃가 넘는 배기 매니폴드의 대류열이 엔진룸으로 전달되므로서, 엔진커버의 열변형이 발생될 뿐만 아니라, 점화코일 호스, OTS센서, TPS센서 등의 각종 전자센서 및 부품들이 열해를 입게되는 문제점이 있었다.Therefore, in the case of the prior art, the convection heat of the exhaust manifold over 200 ° C is transferred to the engine room through a gap provided between the end of the heat protector and the side of the cylinder head, so that not only heat deformation of the engine cover occurs. There was a problem that various electronic sensors and components such as an ignition coil hose, an OTS sensor, and a TPS sensor suffer thermal damage.

따라서 본 발명은 상기와 같은 문제점을 해결하기 위해서 안출된 것으로서, 엔진의 배기열에 의한 엔진룸으로 전달되는 것을 방지하기 위한 히트 프로텍터의 끝단부가 실린더헤드의 일측에 소정 구간 삽입되도록 하므로서 배기매니폴드의 가열에 의한 대류열이 엔진룸으로 전달되는 것을 차단하기 위한 엔진룸의 열해방지를 위한 히트 프로텍터의 결합구조를 제공하는 데 목적이 있다.Therefore, the present invention has been made to solve the above problems, the heating end of the heat protector to prevent the transfer to the engine room by the exhaust heat of the engine is inserted into a predetermined section of one side of the cylinder head heating the exhaust manifold An object of the present invention is to provide a coupling structure of a heat protector for preventing thermal damage of an engine room for preventing convection heat from being transmitted to the engine room.

본 발명은 상기와 같은 목적을 달성하기 위한 수단으로서,The present invention as a means for achieving the above object,

엔진의 운전 과정에서 발생되는 고온의 열이 엔진룸의 다른 부분으로 전달되는 것을 차단하기 위해, 배기 매니폴드의 외측형상을 따라 굴곡된 유선형으로 형성되며, 일측으로는 배기 매니폴드에 부착하기 위한 볼트공이 형성되는 히트 프로텍터에 있어서,In order to block the high temperature heat generated during the operation of the engine to other parts of the engine room, it is formed in a streamlined shape bent along the outer shape of the exhaust manifold, the bolt for attaching to the exhaust manifold on one side In the heat protector in which the ball is formed,

히트 프로텍터의 내측 끝단의 소정 구간이 실린더헤드의 측면벽에 삽입되도록 하기 위한 홈이 실린더헤드의 측면벽에 형성되어, 히트 프로텍터와 실린더헤드의 측벽면 사이 간격이 삭제되는 것을 특징으로 한다.A groove for allowing a predetermined section of the inner end of the heat protector to be inserted into the side wall of the cylinder head is formed in the side wall of the cylinder head, so that the gap between the heat protector and the side wall surface of the cylinder head is eliminated.

이하, 본 발명에 의한 히트 프로텍터 결합구조의 구성 및 작동에 따른 바람직한 실시예를 첨부한 도면과 함께 상세하게 설명한다.Hereinafter, preferred embodiments of the heat protector coupling structure according to the present invention will be described in detail with the accompanying drawings.

도 1은 본 발명에 의해 히트 프로텍터 장착된 상태의 평면도이고, 도 2는 본 발명에 의해 히트 프로텍터가 장착된 상태의 단면도이다.1 is a plan view of a state in which a heat protector is mounted according to the present invention, and FIG. 2 is a cross-sectional view of a state in which a heat protector is mounted according to the present invention.

도면 중에 표시되는 도면부호 20은 본 발명에 의한 엔진을 지시하는 것이고,도면부호 30은 본 발명에 의한 히트 프로텍터를 지시하는 것이다.Reference numeral 20 shown in the figure indicates an engine according to the present invention, and reference numeral 30 indicates a heat protector according to the present invention.

상기한 엔진(20)은 배기 매니폴드(22)가 마련되는 실린더헤드(21)의 측면벽에 히트 프로텍터(30)의 끝단이 삽입되기 위한 홈(23)이 형성되는 것을 제외한 나머지의 일반적인 구성은 종래의 엔진과 같다.The engine 20 has the general configuration except that the groove 23 for inserting the end of the heat protector 30 is formed in the side wall of the cylinder head 21 in which the exhaust manifold 22 is provided. It is like a conventional engine.

상기한 홈(23)은 배기 매니폴드(22)를 통과하는 배기가스의 고열이 엔진룸 측으로 전달되는 것을 방지하기 위한 히트 프로텍터(30)의 내측 끝단이 접하게 되는 선을 따라서 형성되는 것으로, 그 깊이는 3 ~ 6mm 정도로 형성되는 것이 바람직하다. 상기한 실린더헤드(21)의 측면벽에 마련되는 홈(23)에 삽입되는 히트 프로텍터(30)의 삽입구간(D)은 3 ~ 5mm 정도인 것이 바람직하다.The groove 23 is formed along a line where the inner end of the heat protector 30 comes into contact with each other to prevent high heat of exhaust gas passing through the exhaust manifold 22 from being transferred to the engine room side. Is preferably formed about 3 to 6mm. The insertion section D of the heat protector 30 inserted into the groove 23 provided in the side wall of the cylinder head 21 is preferably about 3 to 5 mm.

그리고 상기한 히트 프로텍터(30)의 내측 끝단은 상기한 홈(23)에 삽입될 수 있도록 종래의 히트 프로텍터보다 내측이 조금 길게 형성되는 것이 바람직하다.And the inner end of the heat protector 30 is preferably formed a little longer inside than the conventional heat protector to be inserted into the groove 23 described above.

상기한 히트 프로텍터(30)를 상기한 엔진(20)에 장착하였을 경우에, 종래기술에서 문제가 되어왔던 히트 프로텍터의 내측 끝단과 실린더헤드의 측벽면 사이의 간격이 삭제된다.When the heat protector 30 is mounted on the engine 20, the gap between the inner end of the heat protector and the side wall surface of the cylinder head, which has been a problem in the prior art, is eliminated.

결합시에는 상기 히트 프로텍터(30)의 내측 끝단부를 먼저 홈()에 끼운 다음에 체결볼트(31)로써 고정시키면 된다.At the time of coupling, the inner end of the heat protector 30 may be inserted into the groove () first and then fixed by the fastening bolt 31.

따라서 배기 매니폴드(22)를 통과하는 배기가스에 의한 대류열이 히트 프로텍터(30)와 실린더헤드(21)의 측벽면 사이를 통해서 엔진룸으로 전파되지 않으므로서, 엔진(20)의 상부에 배치되는 점화코일 호스(24), OTS센서(25), TPS센서(26) 등과 같은 각종 센서 및 호스들의 부품들이 열해를 입는 것이 방지되는 것이다.Therefore, the convection heat by the exhaust gas passing through the exhaust manifold 22 does not propagate to the engine room between the heat protector 30 and the side wall surface of the cylinder head 21, and thus is disposed above the engine 20. Parts of various sensors and hoses such as the ignition coil hose 24, the OTS sensor 25, the TPS sensor 26, and the like are prevented from being damaged by heat.

또한, 엔진 커버로 200℃가 넘는 대류열이 직접적으로 전달되지 않으므로서, 엔진 커버의 내구성이 향상되므로서 엔진 커버의 재질변경이 가능하게 된다. 엔진커버의 재질변경은 곧 엔진커버의 원가절감이 이루어지는 것이다.In addition, since convection heat of more than 200 ° C. is not directly transmitted to the engine cover, it is possible to change the material of the engine cover while improving durability of the engine cover. Changing the material of the engine cover will result in cost reduction of the engine cover.

이상과 같이 구성되는 본 발명은 배기 매니폴드를 감싸는 히트 프로텍터와 실린더헤드 측면벽 사이의 간격이 삭제되어, 배기가스가 배기 매니폴드를 통과하는 과정에서 대류되는 열이 직접적으로 엔진의 상부측으로 전파되는 것이 방지되므로서, 고열에 취약한 점화코일 호스, OTS센서, TPS센서 등과 같은 각종 센서 및 호스들의 부품들이 열해를 입는 것이 방지되는 커다란 장점이 있는 것이다.According to the present invention configured as described above, the gap between the heat protector surrounding the exhaust manifold and the cylinder head side wall is eliminated so that the heat that is convective in the course of passing the exhaust gas through the exhaust manifold is directly propagated to the upper side of the engine. Since it is prevented, parts of various sensors and hoses such as an ignition coil hose, an OTS sensor, a TPS sensor, and the like that are vulnerable to high heat are prevented from being damaged by heat.
