Abstract
A protective device is provided for heat emitting structures including but not limited to exhaust manifolds for internal combustion engines. A protective device comprises a double-wall protective screen consisting of two metal sheets which are spaced apart and substantially parallel. The space between the metal sheets is bridged over to support these sheets against each other. The sheets are sealingly connected along their edges so that they enclose between the support points at least one coolant space connected to at least one coolant connection arranged on the edge of the protective screen.
Claims20
A protective device for an exhaust manifold of an internal combustion engine comprising a screen for mounting on the engine and adapted to be spaced from and so shaped to at least partially enclose an exhaust manifold, said screen comprising a pair of substantially parallel spaced metal sheets sealingly connected along their edges, at least one of said sheets having means thereon for bridging the space therebetween to support said sheets at a plurality of points with respect to each other so as to define at least one coolant chamber having interspaces through which a coolant fluid can flow, coolant supply and discharge connection means at an edge of said screen communicating with said coolant chamber, and at least one coolant channel along connected edges of said sheets and said channel communicates with at least one coolant connection and at least one coolant chamber.
