The admission port 14 of induction tract 15 is communicated with in compartment across air-inlet grille 41, and this air-inlet grille 41 is in the window frame bottom being formed at quarter window (quarter window) 40 in mesh-like manner.
Be provided with DYN dynamic fan 17 at the upstream side of gas exhaust duct 16, cooling air is drawn in induction tract 15 from admission port 14 by the negative pressure produced by this fan 17.Front and back a pair pipe-hanging hook 18 suspention of battery 12 (waterproof case 13) through extending along overall width direction is supported on the rear side support 19 of left and right.In addition, battery 12 can be located at separately in waterproof case 13, also can be located in waterproof case 13 as battery unit, and described battery unit, except vehicle battery, also comprises the electric component that the battery such as inverter, DC/DC conv is subsidiary.
Induction tract 15 is formed by being substantially horizontally configured in underfloor first conduit component 20 of baggage room 11 and the upstream side second pipe parts 21 generally perpendicularly configured along the side wall surface 23 on the right side of vehicle and downstream second conduit component 22 at least partially, is connected from upstream side according to upstream side second pipe parts 21, downstream second conduit component 22 with the order of the first conduit component 20.Observe from side, upstream side second pipe parts 21 and downstream second conduit component 22 are in the mode bending (with reference to figure 2) of a part along wheel room 31, observe from rear, a part for upstream side second pipe parts 21 and downstream second conduit component 22 is overlapping with wheel room 31 (with reference to figure 5).
As shown in Figure 4, the section orthogonal with this partial flowpafh being configured at underfloor part of the first conduit component 20 is formed as the flat pattern of length L than the height H length of vertical direction of horizontal direction.The end of downstream side of the first conduit component 20 is connected with the side of the waterproof case 13 of storage battery 12.As shown in Figure 3, the upstream side of the first conduit component 20 forms the curve 24 vertically holded up along side wall surface 23 with large radius of curvature, and is connected (with reference to figure 5) with the lower end of downstream second conduit component 22 by link 25 above curve 24.Connecting portion 45 of the present invention is formed by the upper end of this link 25, first conduit component 20 and the lower end of downstream second conduit component 22.
Referring again to Fig. 5, be provided with groove 26 at the inner peripheral surface of link 25, this groove 26 engages with the engaging protuberance 27 of the lower end being located at downstream second conduit component 22.Thus, the first conduit component 20 is connected in the mode that can load and unload with downstream second conduit component 22.
Upstream side second pipe parts 21 are integrally formed with: line part 21a, and it has admission port 14, and are generally perpendicularly configured along side wall surface 23; Rake 21b, it tilts inside overall width direction from line part 21a; And the connecting portion 21c of linearity, it is extended from rake 21b, and is generally perpendicularly configured medially by overall width direction relative to line part 21a.Projection 29 is provided with in the lower end of upstream side second pipe parts 21, this projection 29 engages with the groove 28 of the upper end being located at downstream second conduit component 22, thus, upstream side second pipe parts 21 are connected in the mode that can load and unload with downstream second conduit component 22.
Downstream second conduit component 22 possesses the bag-shaped foreign matter incorporating section 30 of the foreign matter (not shown) that storage falls from admission port 14.Specifically, branch 22c is provided with at downstream second conduit component 22, this branch 22c branches into the passage 22a be connected with foreign matter the incorporating section 30 and stream 22b be connected with connecting portion 45, to stagger (offset) configuration by the position inside overall width direction than connecting portion 45 in foreign matter incorporating section 30.Branch 22c is in order to avoid forming rib (edge) portion that easily causes noise to produce and by large Surface forming.
Observe from vertical direction, foreign matter incorporating section 30 is more overlapping than branch 22c stream by the upstream section with downstream second conduit component 22.In addition, observe from vertical direction, stagger than the stream section of the stream section of branch 22c downstream and the upstream side of branch 22c.In addition, the stream area of section of the ratio branch 22c downstream of downstream second conduit component 22 and the minimum stream area of section of upstream side second pipe parts 21 roughly equal.
Like this, by foreign matter incorporating section 30 is in staggered configuration inside overall width direction, connecting portion 45 can be configured in the position left outside overall width direction from waterproof case 13, increase the radius of curvature of the curve 24 be connected with connecting portion 45, reduce flow path resistance.In addition, make the minimum stream area of section of the stream area of section of the ratio branch 22c downstream of downstream second conduit component 22 and upstream side second pipe parts 21 roughly equal, make streamline smooth, suppress to supply gas loss, and prevent noise from producing.
In addition, observe from vertical direction, foreign matter incorporating section 30 is more overlapping than branch 22c stream by the upstream section with downstream second conduit component 22, can be reliably accommodated in foreign matter incorporating section 30 by foreign matter thus.On the other hand, observe from vertical direction, stagger than the stream section of the stream section of branch 22c downstream and the upstream side of branch 22c, therefore effectively prevent foreign matter and drop to stream than branch 22c downstream.
As shown in Figure 2, it is shorter than upper width W1 that the vehicle fore-and-aft direction width of the wall of foreign matter incorporating section 30 is formed as lower width W2, thus bottom section is less than top section.Thus, the possibility contacted with the wall of front and back during the acceleration of vehicle or when slowing down is high, inhibits rebounding of the foreign matter fallen, prevents foreign matter to fly out from foreign matter incorporating section 30.
Then, the effect of the present embodiment possessing said structure is described.As shown in the dotted arrow in Fig. 3, the DYN dynamic fan 17 being located at gas exhaust duct 16 is rotated, discharge the air in waterproof case 13 and form negative pressure, thus the air in baggage room 11 is drawn in induction tract 15 (upstream side second pipe parts 21) from admission port 14.
The air be incorporated in upstream side second pipe parts 21 is supplied to waterproof case 13 via downstream second conduit component 22 and the first conduit component 20 as cooling air, after the battery 12 in waterproof case 13 is cooled, be discharged to the rear of the not shown wheel room of the opposition side, wheel room 31 of induction tract side from gas exhaust duct 16.
The area of section of induction tract 15 is set to each part and has the roughly the same area of section, and then the radius of curvature of each curve is set as far as possible large, thereby, it is possible to reduce induction tract 15 flow path resistance, namely to supply gas loss, and inhibit the generation of noise.
In addition, just in case time the foreign matter such as coin, ring falls from admission port 14, this foreign matter by be reliably accommodated in the connecting portion 21c that is positioned at upstream side second pipe parts 21 roughly immediately below foreign matter incorporating section 30, can not enter in waterproof case 13, thus prevent battery to be short-circuited.And then, by downstream second conduit component 22 is unloaded relative to the first conduit component 20 and upstream side second pipe parts 21, the foreign matter be accommodated in foreign matter incorporating section 30 can be taken out from foreign matter incorporating section 30 and reclaim.

And then, because connecting portion 45 is configured in the top of curve 24, therefore, it is possible to guarantee the space in the overall width direction of baggage room 11.
In addition, because second pipe 21,22 is formed in the mode of a part along wheel room 31, therefore, it is possible to be accommodated in side wall surface 23 compactly by second pipe parts 21,22, the side wall surface 23 being separated out baggage room 11 or cabin can be suppressed to protrude to cabin side.
And then, owing to being provided with the foreign matter incorporating section 30 of the foreign matter that storage falls from admission port 14 at downstream second conduit component 22, therefore, even if just in case there is the foreign matter of the electric conductor such as coin, ring to fall from admission port 14, also can be accommodated in foreign matter incorporating section 30, prevent battery 12 to be short-circuited.
In addition, because foreign matter incorporating section 30 is being in staggered configuration by the position inside overall width direction than connecting portion 45, therefore, the radius of curvature from being configured in underfloor first conduit component 20 curve 24 bending above vertical direction can be increased, thereby, it is possible to reduce the aeration resistance of induction tract 15 and cool batteries 12 effectively.
And then, due to second pipe parts by the upstream side second pipe parts 21 with admission port 14 with there is foreign matter incorporating section 30 and downstream second conduit component 22 be connected with the first conduit component 20 is formed, downstream second conduit component 22 can load and unload relative to the first conduit component 20 and upstream side second pipe parts 21, therefore, as required downstream second conduit component 22 with foreign matter incorporating section 30 can be unloaded, be accommodated in the foreign matter in foreign matter incorporating section 30.
In addition, owing to being provided with branch 22c at downstream second conduit component 22, this branch 22c branches into the passage 22a be connected with foreign matter the incorporating section 30 and stream 22b be connected with connecting portion 45, the stream area of section in the downstream of the branch 22c of downstream second conduit component 22 and the minimum stream area of section of upstream side second pipe parts 21 roughly equal, therefore, inhibit the aeration resistance of induction tract 15, and reduce noise, comfortable compartment environment can be obtained.In addition, by second pipe parts being divided into upstream side second pipe parts 21 and downstream second conduit component 22, improve assembleability.
And then, owing to observing from vertical direction, the stream section of the upstream side of the stream section in the downstream of the branch 22c of downstream second conduit component 22 and the branch 22c of downstream second conduit component 22 staggers, and observe from vertical direction, foreign matter incorporating section 30 is overlapping with the stream section of the upstream of the branch 22c of downstream second conduit component 22, therefore, the foreign matter fallen from admission port 14 reliably can be accommodated in foreign matter incorporating section 30, prevent it from invading to battery 12, battery can be prevented thus to be short-circuited.
And then due to foreign matter incorporating section 30, to be configured to bottom section less than top section, therefore inhibits rebounding of the foreign matter dropped in foreign matter incorporating section 30, can be reliably accommodated in foreign matter incorporating section 30 by foreign matter.
