Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is done to detailed description further, but mode of execution of the present utility model is not limited to this.
Embodiment 1:
A kind of automobile gas exhausting manifold branch as depicted in figs. 1 and 2, comprise inlet flange 1, exhaust flange 7 and be vertically connected on a plurality of arms on inlet flange 1, the other end of arm is all communicated with gathering tube 3, one end of described gathering tube 3 is connected with mixing tube 5 by transition tube 4, described exhaust flange 7 is connected on mixing tube 5, described gathering tube 3 is greater than 15 degree and is less than 60 degree with the angle of inlet flange 1, described mixing tube 5 parallels with inlet flange 1, described arm and gathering tube 3 are wrapped with one deck coating 9, in gap between described coating 9 and arm and gathering tube 3, there is current layer 8, between described arm and gathering tube 3 or inlet flange 1, be provided with stiffening rib 10, described stiffening rib 10 is positioned at coating 9.In the present embodiment, inlet flange is connected on motor, and the exhaust of motor is discharged successively after inlet flange 1, arm, gathering tube 3, transition tube 4, mixing tube 5 and exhaust flange 7.Because arm is very short, gas enters gathering tube 3 by arm very soon, 3 pairs of gases of gathering tube tentatively mix, enter again transition tube and mixing tube 5, gas is carried out to secondary mixing, gas is fully mixed, utilize twice mixing, increased the path-length that gas is discharged, the impact force while reducing gas discharge.The exhaust of motor enters gathering tube through arm, be that exhaust meeting produces powerful impact force to gathering tube, the present embodiment is mainly studied the angle between gathering tube inlet flange, scavenging action is studied in the angle of gathering tube, to reduce the impact force of exhaust to gathering tube.By mechanical analysis, shown, parallel with inlet flange when gathering tube, when gathering tube and arm are perpendicular, the impact force of exhaust acts on gathering tube completely, now, exhaust is maximum to the impact force of gathering tube, and now the structure of gas exhaust manifold is least stable, and it mostly adopts this kind of mode existing gas exhaust manifold, and now, gathering tube has certain rebound effect to exhaust, can make part exhaust get back to arm, affects the discharge of exhaust.When gathering tube and inlet flange not parallel, when gathering tube and arm out of plumb, the impact force of scavenging action on gathering tube can be broken off, the power perpendicular to gathering tube direction reduces.Experiment and theory all show, when the angle of gathering tube and inlet flange is larger, but can not equal 90 degree, and its exhaust is less to the impact force of gathering tube.Because gas exhaust manifold is connected on automobile, the space size of its vehicle is limited, and when the angle of gathering tube and inlet flange is larger, its space range taking is larger.Experiment and theory all show, the angle between gathering tube and inlet flange 1 is 60 while spending, and it can reduce half by impact force, and now, the stability of gas exhaust manifold is fine.Angle between gathering tube and inlet flange 1 is less than 15 while spending, though it can reduce impact force, still, its poor effect.Consider, the angle between gathering tube and inlet flange 1 is greater than 15 degree and is less than 60 degree.Due to the limited space of automobile, by transition tube, mixing tube is paralleled with inlet flange, can effectively reduce gas exhaust manifold and take volume, conserve space.Current layer is positioned at outside arm and gathering tube, and because gas exhaust manifold is made of metal, it has good heat-conductive characteristic, and the temperature of the gas that motor is discharged is very high, and exhaust can be heated water rapidly.The maximum temperature of water can reach 100 degrees Celsius, and coolant-temperature gage scatter and disappear slowly than its lost speed of scattering and disappearing of temperature in air, it can keep temperature outside arm in some values for a long time.The rapid rising of water temperature, can effectively reduce the inside and outside temperature difference of arm and gathering tube, and Gao Shike reduces the temperature difference of 100 degrees Celsius, effectively gas exhaust manifold is protected, and reduces gas exhaust manifold cracking situation.Stiffening rib has strengthened the annexation between arm and gathering tube and inlet flange, strengthens the stability of exhaust manifold structure.
