Embodiment
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the present invention, and can not limitation of the present invention being interpreted as.
In order to realize airflow uniform distribution, do not introduce spoiler or projection simultaneously, pipeline and the intake manifold of pipeline before there is this intercooler before embodiments providing a kind of intercooler, by the shape of the air flue of pipeline before change intercooler, reach the effect of the airflow uniform distribution made before intercooler in pipe, thus the uniformity of air-flow before ensure that intercooler, and then improve the utilization ratio of charging efficiency and intercooler.
As shown in Figure 1, it is the structural representation of pipeline before embodiment of the present invention intercooler, before described intercooler, pipeline is made up of the first pipeline 100 be communicated with in turn and the second pipeline 200, namely the second pipeline 200 extends outward from the air outlet of the first pipeline 100, here the suction port 101 of the first pipeline 100 is as the suction port of pipeline before whole intercooler, and the air outlet 201 of the second pipeline is as the air outlet of pipeline before whole intercooler.
Particularly, the Main Function of described first pipeline 100 is that inlet stream is directed to rational Inlet Position, consider intake efficiency, the area substantially constant of the radial cross section of described first pipeline 100, especially, the area of the radial cross section of described first pipeline 100 also will meet certain scope, if this area is excessive, then can cause gas expansion for doing work, thus affect intake efficiency; If this area is too small, then windage loss can be caused excessive, thus also can affect intake efficiency.In a preferred embodiment of the present invention, the area ratio of the area of the radial cross section of the first pipeline 100 any place and the suction port 101 of the first pipeline 100 is set as that 0.82 ~ 1.1 is the most reasonable, and this ratio is most preferably decided to be 0.86 ~ 1.
Further, composition graphs 1 and Fig. 3 a, because a point of direction of airintake direction is contrary with outgassing direction, inlet stream necessarily passes the revolution of 180 °, so arrange revolution place 102 on the first pipeline 100, consider the intake efficiency at this position, the first pipeline 100 also will meet certain scope at the area of the radial cross section of revolution place 102, if this area is too small, then inlet stream can be hindered to pass through; If this area is excessive, then can produce local depression, inlet stream also can be hindered to pass through.
In a preferred embodiment of the present invention, be arranged to minimum by the first pipeline 100 at the area of the radial cross section of revolution place 102, namely the first pipeline 100 is less than the area of the radial cross section at first other position of pipeline 100 at the area of the radial cross section of revolution place 102; In addition, the first pipeline 100 is set as 0.82 ~ 0.9 in the area ratio of the area of the radial cross section of revolution place 102 and the suction port 101 of the first pipeline 100, and this ratio most preferably is 0.86.And, the setting position of above-mentioned revolution place 102 meets: the length of the air outlet of described revolution place 102 to the first pipeline 100 is 0.1 ~ 0.3 with the ratio of the total length of the first pipeline 100, this ratio is preferably 0.16, because the buffering that suitable will be had after this revolution place 102, ensure the even inflation of air-flow, improve intake efficiency.
As depicted in figs. 1 and 2, respectively illustrate the A-A of pipeline before the structural representation of pipeline and the intercooler shown in Fig. 1 before embodiment of the present invention intercooler to generalized section, because the suction port of intercooler is generally plane, although actual airflow face is very complicated, but be linearly by intercooler substantially, so the air outlet (i.e. the air outlet 201 of the second pipeline) of pipeline before intercooler is designed to a corresponding plane.Especially, the shape of the air outlet 201 of described second pipeline is rectangle substantially.
In addition, because all gas all enters intercooler by the air outlet 201 of the second pipeline, think and ensure that the structure shape of the second pipeline 200 is designed to by uniformity of giving vent to anger: as the reference in direction, the planometer at the second place, pipeline 200 air outlet is decided to be horizontal plane, along the direction of air current flow, the area in the first cross section of the second pipeline 200 first diminishes fast, slowly diminish again, here, first cross section refers to the long limit 2012 of the air outlet 201 perpendicular to the second pipeline, and the cross section at place, air outlet 201 plane (referring to horizontal plane as a reference in the present embodiment) perpendicular to the second pipeline.
To sum up, pipeline before the present embodiment intercooler, by means of only changing the sectional area of pipeline, just can to realize making before intercooler the effect of the airflow uniform distribution in pipe, thus the uniformity of air-flow before ensure that intercooler, and then the utilization ratio of raising charging efficiency and intercooler; Do not introduce spoiler or projection, avoid owing to introducing spoiler or projection and the architecture advances of having limited to intake manifold caused, the difficulty of processing adding intake manifold, adding the problems such as the manufacture cost of intake manifold.
In a preferred embodiment of the present invention, described second pipeline 200 equals the area of the suction port 101 of described first pipeline 100 at the area in the first cross section of the first setting place (position at Bm-Bm cutting plane place as shown in Figure 1); Wherein, described first sets the projection be on the air outlet 201 of described second pipeline, to the length l on the long limit 2012 of the air outlet 201 of the perpendicular distance lbm of the first minor face of the air outlet 201 of described second pipeline and described second pipeline
go outratio be 0.43 ~ 0.58, described first minor face is the minor face 2011 (as shown in Figure 1) of suction port 101 side away from described first pipeline 100 of the air outlet 201 of described second pipeline.
Further, in order to improve the uniformity of air-flow further, as shown in Figure 2, the base in the second cross section of described second pipeline 200 comprises the three-arc, the first circular arc and the second circular arc that are connected in turn along described air flow direction, wherein said three-arc and the second circular arc all protrude to the outside of the second pipeline 200, and described first circular arc caves in the inner side of the second pipeline 200; Further, the radius R 3 that the radius R 1 of the first circular arc is greater than radius R 3, the three-arc of three-arc is greater than the radius R 2 of the second circular arc.Here, the second cross section refer to both perpendicular to the air outlet 201 of the second pipeline minor face 2011 and perpendicular to the air outlet 201 place plane of the second pipeline and the cross section of the mid point through described minor face 2011, perpendicular to one another with the first cross section in the second cross section.Especially, the length l on the long limit 2012 of the radius R 1 of described first circular arc and the air outlet 201 of the second pipeline
