At this moment, described intercooler 14 forms long oblong-shaped on vehicular transverse direction.That is to say, intercooler 14 is by long OBL body part 28, be arranged at the intake section 24 of a side of this body part 28, form with the exit portion 25 of the opposite side that is arranged at body part 28, as Figure 14 and shown in Figure 15, when this intake section 24 being provided with band blwr driving engine 5 sides, exit portion 25 is arranged on change-speed box 6 sides, turbine outlet conduit 12 and intercooler entry conductor 13 be arranged on the front look and simultaneously, intercooler delivery channel 15 and entry conductor 16 are arranged on the front look change-speed box 6 fronts overlapping with change-speed box 6 with overlapping band blwr driving engine 5 fwds of blwr driving engine 5.As mentioned above, opening portion from the holistic front bumper 22 of grid, be that the wind of advancing that open lower side part 21 enters is many change-speed box 6 side flow in deflection space, from as described later, after the downside of front bumper 22 is covered by lower cover, extendible portion along the horizontal direction of airfilter output duct 9 flows to the rear, be directed to the following of airfilter 8 simultaneously along the extendible portion up and down of intercooler delivery channel 13 and the change-speed box 6 of entry conductor 16, and flow to the rear along extendible portion, like this, these conduits are cooled off and the change-speed box 6 that leads top after drain to the rear view of vehicle side.At this moment, be provided with battery box 32 above the change-speed box 6, on change-speed box 6 and battery box 32 below between form the passage that the wind direction rear of advancing is spilt.

In addition, as Fig. 1 and shown in Figure 12, the upper end 14a of intercooler 14 is located at than under the low location status of the upper end 21a of the open lower side part 21 of above-mentioned front bumper 22, in the inboard of described front bumper 22, look it is that intercooler 14 is set overlappingly from the vehicle front with the downside 23b of radiator 23 part.Certainly, this intercooler 14 should be arranged on vehicle front as far as possible, and overlooking on the direction at vehicle with described front bumper 22 is the overlapping inboard that is arranged on front bumper 22.Like this, by intercooler being arranged on the inboard of front bumper, making not to need to be presented on the space that is provided with of intercooler essential in the engine room at front bumper rear, be expected to enlarge the car chamber or guarantee the space, to attempt to guarantee the corresponding deformation space that impacts at the rear section of engine room.And, as Fig. 2 and shown in Figure 10, front bumper 22 forms to outstanding circular-arc of vehicle front center side, the following of intake section that the both sides of described intercooler 14 are provided with 24 and exit portion 25 all covered by front bumper 22, and the following of the middle body of intercooler 14 only covered by front bumper 22 in the part of vehicle front side.In addition, the not shown lower cover of the downside of described front bumper 22 covers, and becomes the structure that does not drain to downside by the wind of advancing of intercooler 14.The present invention forms lower cover with board-like material, if do not hinder the place of flowing of the wind of this lower cover then can excise a part yet, and below form the refuse that can leak refuse and spill part.And then, as Fig. 1 and shown in Figure 12, upper end 14a for intercooler 14 passes through the upper end 21a low position of formation than the open lower side part 21 of described front bumper 22, is arranged so that the upper end 14a of intercooler 14 is consistent with the targeting part 29 that opening portion 21 places of front bumper 22 form.Like this, shown in the thick arrow of black of Fig. 1 and Fig. 2, Fig. 6, Figure 12, two aspects of advance wind direction intercooler 14 and radiator 23 that the open lower side part 21 of front bumper 22 is entered flow.In addition, be the advantage of appearance design by such unification, visually make moderate progress.

Form long oblong on the transverse direction of described intercooler 14 vehicles and make the right side part of this intercooler 14 and change-speed box 6 look it is to be provided with overlappingly in the front of vehicle.As shown in Figure 1, that is to say, be controlled at by the height that makes intercooler 14 below half of radiator 23, thereby in the engine room 2 in vehicle 1 the place ahead, the open lower side part 21 of front bumper 22 can not stopped up because of intercooler 14, make radiator 23 expose open lower side part 21 places of upper end, can guarantee the direct-connected leak that connects the wind of advancing of cooling radiator 23, simultaneously, intercooler 14 is arranged on the inboard of front bumper 22, intercooler can be arranged on the prostatitis of vehicle, and, because entering the wind of advancing that cooled off intercooler 14 and radiator 23 from open lower side part 21 rearward spills easily, so, intercooler 14 is maximized on the transverse direction of vehicle, and the right side part and the change-speed box 6 of intercooler 14 look it is to be provided with overlappingly in the vehicle front, are to go out from low change-speed box 6 side leakages of height than band blow-fed engine 5 because cooled off the wind of advancing of intercooler 14 grades, thus the passage of the wind of guaranteeing to advance.

As shown in Figure 9, turbine outlet conduit 12 is to be connected with near the exit portion of the below of blwr 11 sensing is arranged on the dontake pipe 30 in the place ahead of described band blwr driving engine 5, therefore, have the upstream side end parts upward to extension, and the shape of downstream side end parts downward direction extension.

As mentioned above, the top of dontake pipe 30 is provided with airfilter delivery channel 9 and turbine outlet conduit 10, make the wind of advancing be difficult to the structure that spills upward owing to form, so the wind of advancing that enters from the front face side of being with blwr driving engine 5 flows to change-speed box 6 sides at tilted direction, and be difficult for flowing to the direction of band blwr driving engine 5 fwd blwrs 11 and eddy current delivery channel 12.That is to say that the wind of advancing is difficult for the flow direction engine side, thereby can make the catalyst early activityization.As Figure 10 and shown in Figure 12, described intercooler entry conductor 13 be connected with turbine outlet conduit 12 and the upstream side end parts upward to extension, and near the downside 23b of described radiator 23 after extend on the vehicle right side, place at the sidepiece that passes through radiator 23, have to the place ahead of vehicle and extend, and the shape that is communicated with described intake section 24.

And then, on described intercooler 14, form the exit portion 25 of extending to rear view of vehicle, as Fig. 1 and Fig. 2, Fig. 4, Fig. 6, Fig. 8～Figure 14, the intercooler outlet side passage 27 that is communicated with this exit portion 25 is to be formed by intercooler delivery channel 15 and entry conductor 16.And, intercooler delivery channel 15 is the fronts at change-speed box 6, from exit portion 25 near described change-speed box 6, after rearward extending with horizontality, have the shape of extending upward, and be cooled from the wind of advancing that open lower side part 21 enters along the side of the front side of change-speed box 6.Described inlet ducts 16 is the downstream side end parts that connect intercooler delivery channel 15 upward, and has and the shape that is connected to its top extension state, described throttle valve body 17, is cooled by the wind of advancing that enters from open lower side part 21.Like this, so-called intercooler entrance side passage 26 and intercooler outlet side passage 27 are between band blwr driving engine 5 and intercooler 14, with turbine outlet conduit 12 and intercooler entry conductor 13, intercooler 14 and intercooler delivery channel 15 and entry conductor 16, look overlooking direction, be provided with state round radiator 23, intercooler 14 can be maximized on transverse direction, and intercooler 14 and change-speed box 6 are provided with overlappingly, and can present intercooler entry conductor 13 and intercooler delivery channel 15 and 23 of radiatores and do not disturb, can make these conduits revolutions.

As Fig. 1 and Fig. 6, shown in Figure 7, to be arranged on above the described band blwr driving engine 5 than on the high position, the top of described radiator 23, simultaneously, make change-speed box 6 above be arranged on than high position, the upper end of intercooler 14 and than low position, radiator 23 tops, on the case surface of change-speed box case 31, will spill by the wind guiding rear of advancing of intercooler 14.

At this moment, because comparing with the top of band blwr driving engine 5 sides, the top of described change-speed box 6 has the space, therefore the wind of advancing passes through easily, so shown in the thick arrow of black of Fig. 6, be divided into upside and downside flows to rear view of vehicle along the wind of advancing on the case surface of change-speed box case 31, when described change-speed box 6 sides are provided with described intercooler outlet side passage 27, described intercooler entrance side passage 26 is set in band blwr driving engine 5 sides.Thereupon, as Fig. 1 and Fig. 2, shown in the thick arrow of the black of Fig. 6, the wind of advancing is easy to change-speed box 6 side leakages from vehicular transverse direction to rear view of vehicle, when the cooling performance of described intercooler 14 can be improved, because the intercooler delivery channel 15 of formation intercooler outlet side passage 27 and entry conductor 16 possess the part of extending upward along the side of the front side of change-speed box 6, after wind flows along this part of extending upward so advance, flow to rear view of vehicle in case surface along change-speed box case 31, the certain outer circumferential surface section bit flow at intercooler outlet side passage 27 of wind owing to advance can be so that the air inlet of flowing in intercooler outlet side passage 27 obtains the actv. cooling.

In addition, as Fig. 2 and Fig. 4, Fig. 8, Figure 10, Figure 14, shown in Figure 15, make the intake section 24 and the exit portion 25 of described intercooler 14, form outstanding from the vehicular transverse direction of radiator 23, described intercooler entrance side passage 26 and intercooler outlet side passage 27 be side by described radiator 23 at fore-and-aft direction, promptly extend to rear view of vehicle.Thereupon, can utilize and load the remaining space behind band blwr driving engine 5 and the change-speed box 6 and intercooler entrance side passage 26 and intercooler outlet side passage 27 are set, effectively utilize for the spaces in the narrow engine room 2 of described vehicle 1 to contribute.

And then as Fig. 1 and Fig. 2, Fig. 4, shown in Figure 6, battery box 32 is arranged on the top of described change-speed box 6 by body side frame, and the wind of advancing by intercooler 14 also is directed to rear view of vehicle below battery box 32.Owing between described change-speed box 6 and battery box 32, be provided with water pipe 33, so also can cool off to water pipe 33 by the wind of advancing between change-speed box 6 and the battery box 32.

Also have, as shown in Figure 6, water pipe 33 is formed by 2, supplies with usefulness to oil cooler for superposed one, and another root that is positioned at the bottom is supplied with usefulness from oil cooler to water pump.

Also have, as Fig. 2 and Fig. 4, Fig. 6, shown in Figure 7, when the place ahead of described change-speed box 6 is provided with described airfilter 8, make this airfilter 8 following extend to always intercooler 14 near.At this moment, as Figure 6 and Figure 7, the airfilter delivery channel 7 of airfilter 8 is in the side of radiator 23, and is arranged on the top of the exit portion 25 of described intercooler 14.In addition, the airfilter delivery channel 9 of described airfilter 8 is in the back of radiator 23, the top transverse direction along vehicle of radiator 23 is extended to described band blwr driving engine 5 sides, and be connected with described turbine entry duct 10.Like this, between radiator 23 and band blwr driving engine 5, be provided with airfilter delivery channel 9 and turbine entry duct 10, but, obviously find out from the figure mast axis L of Fig. 7, because band blwr driving engine 5 inclination forward tiltedly is provided with, so, make the wind of advancing by radiator 23 be difficult in the top and spill, but advance wind and the wind of advancing by radiator 23 be not only by intercooler 14 all drain to change-speed box 6 places easily.Like this, as shown in figure 12, be provided with catalyst 34 between described radiator 23 and band blwr driving engine 5 fronts, but, owing to all be difficult between radiator 23 and band blwr driving engine 5, spill upward by the arbitrary wind of advancing in intercooler 14 and the radiator 23 at least as mentioned above, like this, even be easy to from change-speed box 6 side leakages trip air intake, but band blwr driving engine 5 fwd exhaust sides also are not easy to spill the wind of advancing, when engine starting owing to can make catalyst 34 early activityizatioies, so can prevent from as far as possible when engine starting, catalyst 34 to be cooled off fully.At this moment, as shown in Figure 9, be respectively equipped with the cooling fan 35 of band blwr driving engine 5 sides and the cooling fan 36 of change-speed box 6 sides at the back side of radiator 23, the cooling fan 36 of change-speed box 6 sides is arranged on cooling fan 35 belows of band blwr driving engine 5, and be arranged on the below of radiator 23, make intercooler 14 be easy to cooling.That is to say, be arranged on the below of the cooling fan 35 of band blwr driving engine 5 sides by cooling fan 36 with change-speed box 6 sides, by the cooling fan 35 of band blwr driving engine 5 sides, the wind of advancing by intercooler 14 is easy to Lou to rear view of vehicle, thereby cools off intercooler 14 more.

As Fig. 1 and Fig. 3, Figure 11, shown in Figure 12, the grid that described front bumper 22 is set, upper end (also can be called " the upper limb ") 14a of promptly described targeting part 29 and intercooler 14, it is overlapping looking in the vehicle front.That is to say that the central part of the open lower side part 21 of front bumper 22 is provided with grid, promptly described targeting part 29 makes the height and position of this targeting part 29 look it is consistent with the upper end 14a of central cooler 14 in the vehicle front.Like this, the wind of advancing that flows into from the open lower side part 21 of front bumper 22 is divided into upper layer side by targeting part 29 and advances wind and lower layer side when advancing wind, the venturi tube structure that utilization causes open lower side part 21 to narrow down gradually by the section form of targeting part 29, and make the advance flow velocity of wind rise.Thereupon, the flow velocity of wind of advancing rise to make the advance temperature of wind low, when the cooling performance that is caused by the wind of advancing is improved, venturi tube structure not only makes flow velocity improve, also can improve the sucking-off effect, so, the air sucking-off at the peripheral position that the wind of advancing can be passed through, thereby, can obtain further cooling performance by advancing wind.

As Fig. 1 and Fig. 2, Figure 10, shown in Figure 12, described front bumper 22 is provided with refuse and spills part 37.This refuse spills the breach sunk part that part 37 forms by the inboard and the central part of front bumper 22 and forms.

And shown in the black arrow of Fig. 1 and Fig. 2, Figure 12, the wind of advancing of being invaded from the open lower side part 21 of front bumper 22 is directed to change-speed box 6 sides.At this moment, even invade,, can discharge at the downside of vehicle 2 then because the deadweight of refuse makes it spill part 37 through described refuse with the refuses such as wind while small stone and dust of advancing.

But symbol 38 is the mounting flange of described induction maniflod 18, and 39 is the installation bracket of described air cleaner inlet conduit 7 usefulness.

Like this, be the oblong-shaped of growing crosswise by making described intercooler 14, and intercooler 14 can be set in the inboard of front bumper 22.In addition, owing to make the upper end 14a of intercooler 14 be positioned at the low position of upper end 21a than the open lower side part 21 of described front bumper 22, by the wind of advancing of open lower side part 21, not only can also play the actv. cooling effect to middle cooling vessel 14 but also to radiator 23.And then, since distinguished and admirable by advancing of described intercooler 14 to low change-speed box 6 sides of height than band blwr driving engine 5, so will advance the wind guiding rearward, the wind of advancing is flowed energetically in change-speed box 6 sides on the case surface of change-speed box case 31.Thereupon, also can cool off air feed in the set intercooler outlet side passage of change-speed box 6 sides 27.

In addition, make the intake section 24 of described intercooler 14 on the vehicular transverse direction of radiator 23, form outstanding with exit portion 25, described intercooler entrance side passage 26 and intercooler outlet side passage 27 extend upward by the side of described radiator 23 and in front and back, and intercooler 14 is more maximized on vehicular transverse direction than radiator 23.In addition, because described intercooler entry conductor 13 and intercooler delivery channel 15 are extended by the side of radiator 23 and at fore-and-aft direction, can prevent that intercooler entry conductor 13 and intercooler delivery channel 15 from bumping with radiator, the revolution of intercooler entry conductor 13 and intercooler delivery channel 15 has also become easily.

And then, above described change-speed box 6, be provided with battery box 32, even owing to also be directed rearward by the following of battery box 32 by the wind of advancing of intercooler 14, by utilize battery box 32 below, the wind of advancing is flowed fully in change-speed box 6 sides, and then, can improve the cooling performance of intercooler 14.

Also have, when the place ahead of described change-speed box 6 is provided with airfilter 8, by make this airfilter 8 below extend to intercooler 14 near, owing to make the overlapping setting of downside of intercooler 14 and radiator 23, so look in the vehicle front with intercooler 14 not overlap, can be so that airfilter 8 following extends downwards, and can make airfilter 8 maximizations.In addition, can utilize the guiding of the following conduct of airfilter 8 by the wind of advancing of described intercooler 14.

Also have, because set grid on the described front bumper 22, it is the upper limb of targeting part 29 and intercooler 14, promptly upper end 14a looks overlapping in the vehicle front, vehicle front for vehicle 1 looks, the targeting part 29 of described front bumper 22 and the upper end 14a of intercooler 14 are a surface state, and the design that makes the vehicle front of vehicle 1 look good, increases in appearance.

And then, spill part 37 by on described front bumper 22, being provided with refuse, invading from the open lower side part 21 of front bumper 22 when advancing wind, shown in the thick arrow of black of Fig. 1 and Fig. 2, Figure 12, can guide to change-speed box 6 sides, suppose and advance wind when invading the refuse of small stone or dust etc. simultaneously, because focusing on certainly when spilling part 37 through described refuse of refuse can be discharged from the downside of vehicle 2.
