각각의 연소실에서 배출되는 배기가스는 배기 매니폴드를 통해 한 곳으로 모 인 다음 배기 파이프를 따라 대기중으로 배출된다. 그리고, 배기 파이프의 도중에는 촉매컨버터 및 소음기가 장착되어 배기가스 중에 포함된 오염물질을 정화하고, 대기중으로 방출되는 소음을 감쇠시킨다.The exhaust gases from each combustion chamber are gathered in one place through the exhaust manifold and then released to the atmosphere along the exhaust pipe. In the middle of the exhaust pipe, a catalytic converter and a silencer are mounted to purify the contaminants contained in the exhaust gas and attenuate the noise emitted to the atmosphere.

그리고, 상기한 배기 매니폴드와 배기 파이프를 통과하는 배기가스의 고열이 엔진룸과 차체 및 실내바닥에 전달되는 것을 방지하기 위해 배기 매니폴드와 배기 파이프는 그 상부를 히트 프로텍터(Heat protector)로 감싸게 된다.The exhaust manifold and the exhaust pipe may be covered with a heat protector to prevent the high temperature of the exhaust gas passing through the exhaust manifold and the exhaust pipe from being transmitted to the engine compartment, the vehicle body, and the indoor floor. do.

이중 배기 파이프용 히트 프로텍터(1)는, 도 1에 도시된 바와 같이, 스틸이나 알루미늄 재질로 이루어진 1 겹의 얇은 박판(2)을 배기 파이프의 형상으로 성형하여 열을 차단하도록 이루어져 있으며, 도 2에 도시한 바와 같이, 박판(2)에 엠보싱(Embossing) 처리를 하여 공기와 접촉하는 단면적을 넓힘으로써 열교환이 원활하게 이루어지도록 되어 있다.As shown in FIG. 1, the heat protector 1 for the double exhaust pipe is configured to block heat by forming a single thin sheet 2 made of steel or aluminum into a shape of an exhaust pipe. As shown in the figure, the thin plate 2 is embossed to increase the cross-sectional area in contact with air so that heat exchange can be performed smoothly.

최근의 자동차들은 배기량이 지속적으로 커지고 있는 상황으로서, 이에 따라 엔진으로부터 배출되는 배기가스에서 발생하는 열이 점차 상승하고 있는 추세이다.In recent years, the exhaust gas is continuously increasing, and thus heat generated from exhaust gas emitted from the engine is gradually increasing.

그런데, 종래의 히트 프로텍터는, 1 겹의 얇은 박판으로만 이루어져 있어, 나날이 상승하는 배기가스의 열을 효과적으로 차단할 수 없는 문제점이 있었다.By the way, the conventional heat protector consists only of one layer of thin thin plates, and there existed a problem which cannot effectively block the heat of exhaust gas which rises day by day.

이에 본 발명은 상기와 같은 점을 종래기술의 문제점을 해소하기 위해 안출한 것으로, 열 차단 성능을 현저히 향상시킬 수 있는 자동차의 히트 프로텍터를 제공하는 데에 그 목적이 있다.Accordingly, the present invention has been made in view of the above problems to solve the problems of the prior art, and an object thereof is to provide a heat protector of a vehicle that can significantly improve the heat shield performance.

상기 목적을 달성하기 위한 본 발명에 따른 자동차의 히트 프로텍터는, 엠보싱 처리된 제 1박판과; 상기 제 1박판의 상면에 부착되고, S 자형상이 대칭되면서 반복적으로 이어지도록 성형되어 반복되는 각 굴곡부 내부에 에어갭이 형성된 제 2박판과; 상기 제 2박판의 상면에 부착되고, 평평한 복수겹의 판재로 이루어진 제 3박판으로 구성된다.In order to achieve the above object, a heat protector of an automobile according to the present invention comprises: an embossed first thin plate; A second thin plate attached to an upper surface of the first thin plate, and having an air gap formed in each of the bent portions which are S-shaped shapes are symmetrically and repeatedly connected; It is attached to the upper surface of the second thin plate, and consists of a third thin plate made of a plurality of flat plate material.
