Abstract
The invention relates to an exhaust pipe which comprises a main exhaust pipeline, a first auxiliary exhaust pipeline, a second auxiliary exhaust pipeline. One ends of the first auxiliary exhaust pipeline and the second auxiliary exhaust pipeline are communicated with the main exhaust pipeline, a position where the first auxiliary exhaust pipeline is connected with the main exhaust pipeline is positioned on the upper reach of a position where the second auxiliary exhaust pipeline is connected with the main exhaust pipeline, or the position where the first auxiliary exhaust pipeline is connected with the main exhaust pipeline and the position where the second exhaust pipeline is connected with the main exhaust pipeline are symmetrical. The exhaust pipe has the advantages of smoothness in exhaust and good heat-radiating effect.
Description
Technical field
The present invention relates to a kind of outlet pipe.
Background technique
Outlet pipe is installed between engine exhaust and silencing apparatus, makes whole vent systems be Flexible spacecraft, thus plays vibration and noise reducing, the convenient effect of installing and extending the exhausting silencer system life-span.Existing outlet pipe is generally one pipeline, because the diameter of air outlet flue can not arbitrarily expand, therefore, such outlet pipe is for the larger motor of discharge capacity, the speed of exhaust is restricted, and not only can have influence on the work of motor, but also the heat increased the weight of on outlet pipe accumulates.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of outlet pipe of smooth in exhaust.
The technological scheme solved the problems of the technologies described above is as follows:
Outlet pipe, comprise main exhaust pipeline, also comprise the first secondary exhaust duct and the second secondary exhaust duct, one end of first secondary exhaust duct and the second secondary exhaust duct all with main exhaust pipeline communication, the connection part of the first secondary exhaust duct and main exhaust pipeline, be positioned at the upstream of the connection part of the second secondary exhaust duct and main exhaust pipeline, or the connection part of the first secondary exhaust duct and main exhaust pipeline, and the connection part of the second secondary exhaust duct and main exhaust pipeline is arranged symmetrically.
Have employed such scheme, also comprise the first secondary exhaust duct and the second secondary exhaust duct, one end of first secondary exhaust duct and the second secondary exhaust duct all with main exhaust pipeline communication, by the first secondary exhaust duct and the second secondary exhaust duct, expand the exhaust space of main exhaust pipeline, add the connection part of the first secondary exhaust duct and main exhaust pipeline, be positioned at the upstream of the connection part of the second secondary exhaust duct and main exhaust pipeline, this mode that first secondary exhaust duct and the second secondary exhaust duct dislocation are arranged, can air-flow be successfully made to shunt, avoid air-flow that the rough sledding of backflow occurs when shunting.
Described first secondary exhaust duct and the second secondary exhaust duct all wrap up a heat-transfer device, this heat-transfer device comprises internal heat conduction pipe, fin and outer heat dissipating pipe, one end of fin is connected with the outer wall of internal heat conduction pipe, the other end of fin and the internal face of outer heat dissipating pipe, internal heat conduction pipe is close to the first secondary exhaust duct or the second secondary exhaust duct.By heat-transfer device, rapidly the transfer of heat on the first secondary exhaust duct and the second secondary exhaust duct can be distributed, thus reduce the heat on the first secondary exhaust duct and the second secondary exhaust duct.
The outer wall of described main exhaust pipeline is equipped with heat dissipating layer.The outer wall of outer heat dissipating pipe is provided with heat dissipating layer.By heat dissipating layer, be conducive to absorbing the heat on main exhaust pipeline and sink rapidly, because main exhaust pipeline and sink expose in atmosphere, therefore, heat can Quick diffusing, create a further reduction the heat on main exhaust pipeline and sink.
Accompanying drawing explanation
Fig. 1 is the structural representation of outlet pipe;
Fig. 2 is the schematic diagram of heat-transfer device in the present invention;
1 is main exhaust pipeline, and 2 is the first secondary exhaust duct, and 3 is the second secondary exhaust duct, and 4 is heat dissipating layer, and 5 is heat-transfer device, and 6 is internal heat conduction pipe, and 7 is fin, and 8 is outer heat dissipating pipe, and 9 is heat dissipating layer.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
See figures.1.and.2, outlet pipe of the present invention, comprises main exhaust pipeline 1, the outer wall of main exhaust pipeline is equipped with heat dissipating layer 4.Also comprise the first secondary exhaust duct 2 and the second secondary exhaust duct 3, one end of first secondary exhaust duct 2 and the second secondary exhaust duct 3 all with main exhaust pipeline communication, the connection part of the first secondary exhaust duct 2 and main exhaust pipeline 1, be positioned at the upstream of the connection part of the second secondary outlet pipe 3 road and main exhaust pipeline 1, or the connection part of the first secondary exhaust duct 2 and main exhaust pipeline 1, and the second secondary exhaust duct 3 is arranged symmetrically with the connection part of main exhaust pipeline 1.First secondary exhaust duct and the second secondary exhaust duct all wrap up a heat-transfer device 5, this heat-transfer device comprises internal heat conduction pipe 6, fin 7 and outer heat dissipating pipe 8, one end of fin 7 is connected with the outer wall of internal heat conduction pipe 6, the other end of fin 7 and the internal face of outer heat dissipating pipe 8, internal heat conduction pipe 6 is close to the first secondary exhaust duct 2 or the second secondary exhaust duct 3.The outer wall of outer heat dissipating pipe 7 is provided with heat dissipating layer 9.Heat dissipating layer 4 on main exhaust pipeline 1 and the heat dissipating layer 9 on outer heat dissipating pipe 7 all include nano carbon microsphere.
