Accompanying drawing explanation
Fig. 1 is the utility model the first embodiment's structural representation;
Fig. 2 is the side view of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As illustrated in fig. 1 and 2, for the utility model the first embodiment's structural representation, a kind of exhaust manifold thermal shield, comprise: comprising: a cover body, described cover body comprises the first backplate 2, arc backplate 1, the second backplate 3 and the 3rd backplate 4, the first side of described the first backplate 2 is connected with arc backplate 1, and the second side of described the first backplate 2 is connected with the second backplate 3 and the 3rd backplate 4, and described the second backplate and the 3rd backplate are oppositely arranged; Described the second backplate becomes an inclination angle to arrange with described the first backplate, described the 3rd backplate becomes an inclination angle to arrange with the first backplate;
Each backplate forms by three layers, comprises skin and is formed on the thermal-protective coating between skin, and described skin is sheet metal.
Exhaust manifold thermal shield of the present utility model, by improving the structure of exhaust manifold thermal shield, increases the heat insulation area of both sides, reaches the radiation heat of isolated gas exhaust manifold to fan electromotor, ECU and negative pole wire harness (gearshift zip place).And this thermal shield forms by three layers, greatly reduce the thermal radiation that parts are subject to around.
The second backplate of the present utility model becomes 80-100 degree with described the first backplate, is preferably 90 degree, and the second backplate is vertical with the first backplate arranges.When the second backplate is installed, just to automobile ECU part, wrap the gas exhaust manifold in this region, greatly reduce the temperature on ECU surface, these electronic components can be worked under normal temperature environment.
The 3rd backplate of the present utility model becomes 80-100 degree with described the first backplate, is preferably 90 degree, and the 3rd backplate is vertical with the first backplate arranges.The 3rd backplate has wrapped the high-temperature exhaust air manifold of the inside when mounted, the radiation of the high temperature heat radiation that has stopped gas exhaust manifold to the 3rd backplate outside.Because this motor is front exhaust; what the 3rd backplate was just right is radiator fan motor; thereby the radiator fan motor of having protected the 3rd backplate outside to arrange; avoid the thermal radiation of gas exhaust manifold; greatly reduce the temperature on fan electromotor surface, this fan electromotor can be worked under normal temperature environment.
In a kind of embodiment preferably, the first side of described the first backplate 2 is formed with draw-in groove, on described arc backplate, is formed with flange, and described arc backplate is connected in the draw-in groove of the first side of the first backplate by described flange, is convenient to dismounting.Described the second backplate 3 is connected with described the first backplate by flexible connection piece respectively with the 3rd backplate 4, is convenient to adjust the inclination angle of the second backplate and the 3rd backplate.Preferably, described arc backplate is provided with mounting hole, in described mounting hole, embeds and has telescopic connecting rod.When mounted, described connecting rod is taken out and installed.In the time of laying state, described connecting rod is embedded in mounting hole.
The external thermal radiation capability of object is directly proportional to 4 powers of himself surface temperature, and thermal radiation is along rectilinear propagation.Under some operating mode, such as 60kph, under 7.2% gradient, gas exhaust manifold surface temperature can reach 450 ℃, and its heat shield surface only has 150 ℃.The thermal shield of this three-decker can greatly reduce the thermal radiation that parts are subject to around.In the middle of this three-decker, be the thermal-protective coating of asbestos, two outside layers is aludip.
After having adopted novel exhaust manifold thermal shield, under identical operating condition of test, the temperature of ECU is reduced to 102 ℃, the temperature of fan electromotor and is reduced to 126.1 ℃, and the temperature of negative pole wire harness (gearshift zip place) is reduced to 125.3, meet design requirement, get rid of heat evil risk.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
