Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, 1 is an engine room formed at the front of the vehicle, 2 is a front right fan, and 3 is a right front side frame.

A radiator 4 is provided in the center of the front part of the engine room 1 so as to extend in the vehicle width direction and in the vertical direction. The radiator 4 is disposed in the vicinity of the radiator 4, more specifically, to the right of the radiator 4 and at a lower position. A battery 5 as an in-vehicle device is arranged in the rear of the drying room. The radiator 4 is provided with a pair of electric fans 6 and 7, and the cooling air can pass through the radiator 4 by driving the electric fans 6 and 7 even when the vehicle is stopped. The passing air after passing through the radiator 4 is considered to be warm air having a considerably high temperature. Then, behind the radiator 4, the engine 8 is provided with the engine 8 in a horizontal position, for example.

Reference numeral 11 in FIG. 1 denotes an outside air introduction duct, and the outside air introduced into this outside air introduction duct 11 is used as intake air for combustion of the engine 8. The outside air introduction duct 11 is arranged as follows. That is, as shown in FIGS. 2 and 3, the tip of the outside air introduction duct, that is, the outside air introduction opening 11 a is located between the radiator 4 and the battery 5. The outside air introduction duct 11 extends rearward from the introduction opening 11a, then extends substantially vertically downward, and then extends rearward along the front side frame 3 and finally the engine 8 (Air cleaner for use). Such an outside air introduction duct 11 is located between the radiator 3 and the battery 5 in the vehicle width direction near the radiator 4 and the battery 5.

A seal plate 12 is disposed on the surface of the outside air introducing duct 11 on the inner side in the vehicle width direction, that is, the surface on the radiator 4 side. The seal plate 12 extends in the front-rear direction from the radiator 4 to slightly behind the battery 5, and in the up-down direction from a position slightly lower than the battery 5 to a position near an intermediate high position of the front side frame 3. It is growing.

The upper surface height position of the battery 5 is higher than the upper surface height position of the radiator 4, and therefore the upper end height position of the seal plate 12 is higher than the upper surface of the radiator 4. Has been done. Further, the above-mentioned setting of the seal plate 12 makes it possible to expect a function as a guide plate for guiding the passage of the wind passing through the radiator 4 toward the engine 8.

On the surface of the seal plate 12 on the battery 5 side, two upper and lower baffle plates 13 and 14 are provided in a protruding manner (not shown in FIG. 1). Each of the baffle portions 13 and 14 extends in a substantially horizontal direction, and the lower baffle portion 13 is set at a substantially intermediate height position of the front side frame 3 and the frame 3 (of It is designed to reach the inner side surface in the vehicle width direction). Further, the baffle plate portion 14 located above is set at a position slightly higher than the front side frame 3 and is attached to the wheel apron 9 which constitutes the vehicle width direction outer side surface of the front side frame 3. It is said that it will reach up to.

The seal plate 12 described above may be formed separately from the outside air introducing duct 11, but as shown in FIG. 4, the sealing plate 12 should be integrally formed with the outside air introducing duct 11. You can This integral molding can be performed by, for example, blow molding.

In the above structure, the hot air that has passed through the radiator 4 is obstructed by the seal plate 12 and is prevented from flowing toward the battery 5 and the introduction opening 11a of the outside air introduction duct. . This is preferable for preventing thermal deterioration of the battery 5 (preventing early evaporation of the battery liquid, etc.) and for ensuring sufficient filling efficiency by making the outside air supplied to the engine 8 as cold as possible. Further, although water may be contained in the wind passing through the radiator 4, the water is similarly prevented from reaching the battery 5 and the outside air introduction opening 11a.

The water bounced off the road surface due to traveling in a puddle or the like is prevented by the baffle plates 13 and 14 from splashing further upward. As a result, the battery 5 can be protected from water, and a situation in which water is sucked in from the outside air introduction duct 11 is reliably prevented.

The seal plate 12 smoothly guides the passing air that has passed through the radiator 4 to the engine 8 and is also preferable for cooling the engine 8. Particularly, as in the embodiment, the guide action can be improved by setting the seal plate 12 so as to be gradually positioned inward in the vehicle width direction toward the rear.

Although the embodiment has been described above, as an in-vehicle device corresponding to the battery 5, in addition to this, a brake control valve device (for example, for an ABS device or a traction device), etc. Can be a device. Further, the arrangement of the engine 8 is not necessarily limited to the rear of the radiator 4 (on the moving path of the passing wind), and the arrangement relationship between the both 4 and 8 can be set appropriately.
