Description
본 고안은 배기가스열에 의해 주변 부재들이 손상되지 않도록 열의 방출을 차단시켜 주기 위한 촉매변환기 케이스의 단열 구조에 관한 것이다.The present invention relates to a thermal insulation structure of the catalytic converter case for blocking the release of heat so that the peripheral members are not damaged by the exhaust gas heat.
종래 배기가스를 정화하기 위한 담체(촉매)는 도 2에 도시하는 것과 같은 형상의 촉매변환기 케이스(10)내에 내장되어 있다.A carrier (catalyst) for purifying conventional exhaust gas is incorporated in a catalytic converter case 10 having a shape as shown in FIG.
그런데 담체는 배기가스 열에 지속적으로 노출되어 있기 때문에 케이스(10)를 통해 방출되는 열에 의하여 주변 부품들이 열손상을 입게 되는 문제점이 있다.However, since the carrier is continuously exposed to the heat of the exhaust gas, there is a problem that the peripheral parts are damaged by heat emitted through the case 10.
이를 방지하기 위해 통상 케이스(10) 외부에 히트카버를 장착하여 단열 처리하고 있으나 이는 히트카버 장착을 위한 플랜지 형성과 볼트 등 여러 가지 부품이 소요되므로 구조가 복잡해지고 비용이 증대되는 문제점이 따르게 된다.In order to prevent this, the heat cover is usually mounted on the outside of the case 10 to insulate the heat cover. However, since various components such as flange formation and bolts are required for mounting the heat cover, the structure becomes complicated and the cost increases.
이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 바는 촉매변환기 케이스를 통해 배기가스열이 방열되어 주변 부품들을 손상시키는 것을 방지하는 촉매변환기의 단열구조를 제공하는 데 있다.Therefore, the present invention has been proposed in view of the above problems, and its object is to provide a heat insulation structure of a catalytic converter that prevents heat from exhaust gas being radiated through the catalytic converter case to damage surrounding components.
상기한 목적을 달성하기 위한 본 고안의 수단은 배기가스를 정화하는 담체 보호용 촉매변환기 케이스에 있어서, 상기 촉매변환기 케이스의 몸체는 빈공간부에 의해 내벽몸체와 외벽몸체로 구분되어 상기 내벽몸체의 열이 외벽몸체로 전달되는 것을 차단하게 되는 것임을 특징으로 한다.Means of the present invention for achieving the above object is a catalytic converter case for protecting the exhaust gas purifying, the body of the catalytic converter case is divided into an inner wall body and the outer wall body by the empty space to the heat of the inner wall body Characterized in that it is to block the transmission to the outer wall body.

이하 본 고안의 실시예를 첨부한 도면을 참조하여 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
도 1은 본 고안에 의한 촉매변환기 케이스의 단열 구조를 보여주는 단면도로서 도면에 있어서 부호 1은 촉매변환기 케이스이다.1 is a cross-sectional view showing a heat insulation structure of the catalytic converter case according to the present invention, the reference numeral 1 in the drawings is a catalytic converter case.
촉매변환기 케이스(1)의 중공부(2)에는 배기매니폴드를 거쳐 배기되는 배기가스의 유해 성분을 산화 환원시켜 정화하는 담체(촉매)가 내장되며 촉매변환기 케이스(1)의 몸체는 빈공간부(3)에 의해 내벽몸체(4)와 외벽몸체(5)로 구분된다.The hollow part 2 of the catalytic converter case 1 includes a carrier (catalyst) for redoxing and purifying harmful components of exhaust gas exhausted through the exhaust manifold, and the body of the catalytic converter case 1 has an empty space ( 3) the inner wall body (4) and the outer wall body (5).
상기 빈공간부(3)에는 공기가 충진되며 내벽몸체(4)에 전달된 배기가스의 열은 우수한 단열재중 하나인 빈공간부(3)내의 공기층에 의해 외벽몸체(5)로 전달되는 것이 차단되어지므로 효과적인 단열이 가능하여 열의 외부 확산을 방지하게 되는 것이다.The empty space part 3 is filled with air, and the heat of the exhaust gas delivered to the inner wall body 4 is blocked from being transmitted to the outer wall body 5 by the air layer in the empty space part 3, which is one of excellent heat insulating materials. Effective insulation is possible to prevent external diffusion of heat.
이상과 같은 본 고안에 의한 촉매변환기 케이스의 단열구조에 의하면 촉매변환기 케이스의 몸체를 공기가 충진되는 빈공간부에 의해 내벽몸체와 외벽몸체로 구분되어지게 되므로써 마치 보온병과 같은 워리에 의해 내벽몸체에 전달된 배기가스열이 공기층에 의해 외벽몸체로 전달되는 것이 차단되어지게 되므로 열의 외부 확산에 따른 주변 부재들의 열화를 방지하며 그 구조가 간단하므로 저렴한 비용으로 단열효과를 얻게 된다.According to the adiabatic structure of the catalytic converter case according to the present invention as described above, the body of the catalytic converter case is divided into an inner wall body and an outer wall body by an empty space filled with air, so that it is transferred to the inner wall body by a war such as a thermos. Since the exhaust gas heat is blocked from being transmitted to the outer wall body by the air layer, the deterioration of the peripheral members due to the external diffusion of heat is prevented, and the structure thereof is simple, so that the heat insulating effect is obtained at low cost.
