Detailed description of the invention

Please join shown in Fig. 1 to Fig. 5, this utility model discloses a kind of electric hybrid module 100, in order to process the aerofluxus of electromotor (such as high-power engine).On the whole, described electric hybrid module 100 includes housing 1, the some dividing plates 2 being installed in described housing 1 and the mixing arrangement 3 being at least partially disposed in described housing.Wherein said some dividing plates 2 include spaced first dividing plate 21 and second partition 22.Described housing 1 is separated into the first cavity 41 of the upstream at described first dividing plate 21, the second cavity 42 between described first dividing plate 21 and described second partition 22 and is positioned at the 3rd cavity 43 in downstream of described second partition 22 by described first dividing plate 21 and described second partition 22.Described mixing arrangement 3 is at least partly supported by described first dividing plate 21.

Described mixing arrangement 3 includes inlet tube 31 and is parallel to the mixing tube 32 of described inlet tube 31, and wherein said inlet tube 31 is provided with the first outer surface 311 and runs through some perforation 312 of described first outer surface 311.Please join shown in Fig. 4 and Fig. 5, described inlet tube 31 is to seal near the end face 313 of described first dividing plate 21.

Please join shown in Fig. 1 and Fig. 5, described electric hybrid module 100 includes installing urea nozzle (not shown) so that the urea liquid after atomization is sprayed into the nozzle mounting seat 11 in described mixing tube 32.

Described mixing tube 32 includes the second outer surface 321, the some spinning disks 322 being positioned on described second outer surface 321, is positioned at the side of described spinning disk 322 and near some first perforation 323 of described nozzle mounting seat 11 and be positioned at the opposite side of described spinning disk 322 and near some second perforation 324 of described first dividing plate 21, and described first perforation 323 is bored a hole with described second and 324 is all connected with described first cavity 41.Described mixing tube 32 includes extending beyond described first dividing plate 21 to enter the extension 325 in described second cavity 42.

Described second partition 22 includes at least one through hole 221 connecting described second cavity 42 with described 3rd cavity 43.Described electric hybrid module 100 also includes the kuppe 5 being fixed on described second partition 22 and aliging with described mixing tube 32.Described mixing tube 32 is the most spaced with described kuppe 5, and described extension 325 does not extends in described kuppe 5.Described kuppe 5 is provided with towards the opening 51 of described mixing tube 32 and in order to change the inner surface 52 of the arc-shaped in air current flow direction.Described opening 51 connects with described second cavity 42.In this utility model embodiment illustrated, the diameter of described opening 51 is more than the diameter of described extension 325, to guarantee that more air-flow can under kuppe 5 acts on reversely.Described kuppe 5 at least partly protrudes in described 3rd cavity 43.It addition, described electric hybrid module 100 also includes the outlet 12 connected with described 3rd cavity 43.
