An exhaust manifold heat dissipation cover coupling device for thermal stress and vibration deflection is proposed. The device has a function of preventing wear of a heat dissipation cover to couple an exhaust manifold heat dissipation cover, the device being able to improve the durability of various parts including a heat dissipation cover by attenuating multi-directional vibration that is transmitted from an exhaust manifold when the heat dissipation cover is installed outside the exhaust manifold, being able to prevent damage to parts due to thermal stress by flexibly coping with thermal deformation such as thermal contraction or thermal expansion even if the thermal deformation is generated by high-temperature heat transmitted from the exhaust manifold, and being able to prevent frictional damage of the heat dissipation cover due to friction by a component that slides to attenuate vibration.

An insulation structure of catalytic converter of vehicle according to an exemplary embodiment of the present invention includes an LNT converter. A connecting housing is provided such that a urea reducing agent is injected to the exhaust gas when it is needed. An SDPF converter reduces nitrogen oxide contained in the exhaust gas using the injected reducing agent, and SCR catalyst is coated on a filter. An insulation cover including inner surface contacts the LNT converter, the connecting housing and the SDPF converter and also includes an outer surface which is opposing surface to the inner surface and surrounds the LNT converter, the connecting housing and the SDPF converter. The insulation cover insulates heat generated from the LNT converter, the connecting housing and the SDPF converter. An insulation material is inserted and attached between the outer surface and the inner surface of the insulation cover.

Disclosed is an insulation fiber composite. In particular, a surface of the insulation fiber composite is substantially improved such that a shape of three dimensions can be maintained as a heat resisting fiber and an insulation material are integrated. The insulation fiber composite of the present invention has excellent formability and surface property and comprises an insulation layer; and a pair of inorganic fiber layers. A first inorganic fiber layer of the pair is stacked on an upper surface of the insulation layer and a second inorganic fiber layer is stacked on a lower surface of the insulation layer, respectively. In particular, each the inorganic fiber layers has a greater planar surface area than a planar surface area of the insulation layer such that the insulation is not exposed to an exterior when the insulation layer and the pair of the inorganic fiber layers are stacked.
