Abstract

<P>PROBLEM TO BE SOLVED: To sufficiently exhibit capacity of a radiator. <P>SOLUTION: The radiator 20 and spare tire 30 are disposed in a trunk 43 in a widening shape toward the end so that the distance L1 between the upper end side of the spare tire 30 and the upper end side of the radiator 20 is shorter than the distance L2 between the lower end side of the spare tire 30 and the lower end side of the radiator 20. Thus, while the air pressure (static pressure) on the back side of the radiator 20 is suppressed from increasing near the upside, substantially whole amount of cooling wind passing through the radiator 20 is certainly turned downward and can be discharged out of the trunk 43. Therefore, the air having passed through the radiator 20 can be discharged to the downside while the amount of the cooling wind passing through the upper end side of the radiator 20 is suppressed from decreasing comparing with the amount of the cooling wind passing through the lower end side of the radiator 20. A heat dissipation capacity of the radiator 20 can fully be exhibited. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

【０００１】
【発明の属する技術分野】
本発明は、ラジエータ等の熱交換器及びスペアタイヤが前端側に搭載された車両のうち、スペアタイヤが熱交換器の空気流れ下流側に配置された車両の前端構造に関するものである。
【０００２】
【従来の技術】
ラジエータ等の車両前端側に搭載される熱交換器を通過した冷却風は、走行風が流れる下方側からトランクルーム外に排出することが望ましい。
【０００３】
そこで、従来は、図２に示すように、ラジエータ２０を鉛直に配置した状態で、スペアタイヤ３０の上端側を下端側より車両前方側に位置するように鉛直方向に対して傾けることにより、ラジエータ２０を通過した冷却風を、スペアタイヤ３０に衝突させるようにして下方側に転向させて下方側からトランクルーム外に排出している（例えば、特許文献１参照）。
【０００４】
【特許文献１】
実開平６−７５９６８号公報
【０００５】
【発明が解決しようとする課題】
ところで、特許文献１に記載発明では、ラジエータ２０が略鉛直に配置されているのに対してスペアタイヤ３０は鉛直方向に対して傾いているので、スペアタイヤ３０の上端側に向かうほど、スペアタイヤ３０とラジエータ２０との距離が小さくなる。
【０００６】
このため、スペアタイヤ３０に衝突して下方側に転向した空気が流れることができる通路部分、つまりスペアタイヤ３０とラジエータ２０との距離が上方側に向かうほど小さくなり、ラジエータ２０の背面側における空気圧が上方側に向かうほど高くなる。
【０００７】
このため、ラジエータ２０の上端側を通過する冷却風の風量が、ラジエータ２０の下端側を通過する冷却風の風量に比べて小さくなってしまうので、ラジエータ２０の放熱能力を十分に発揮させることが難しい。
【０００８】
本発明は、上記点に鑑み、第１には、従来と異なる新規な車両の前端構造を提供し、第２には、ラジエータ等の熱交換器の能力を十分に発揮させることを目的とする。
【０００９】
【課題を解決するための手段】
本発明は、上記目的を達成するために、請求項１に記載の発明では、熱交換器（２０）及びスペアタイヤ（３０）が前端側に搭載された車両に適用され、スペアタイヤ（３０）が熱交換器（２０）の空気流れ下流側に配置され、かつ、熱交換器（２０）及びスペアタイヤ（３０）が収容された空間（４３）の上方側が閉塞された車両の前端構造であって、スペアタイヤ（３０）は、上端側が下端側より車両前方側に位置するように鉛直方向に対して傾いており、熱交換器（２０）は、上端側が下端側より車両前方側に位置するように鉛直方向に対して傾いており、さらに、スペアタイヤ（３０）の上端側と熱交換器（２０）の上端側との距離（Ｌ１）は、スペアタイヤ（３０）の下端側と熱交換器（２０）の下端側との距離（Ｌ２）より小さいことを特徴とする。
【００１０】
ところで、熱交換器（２０）の背面側における空気圧を全域に渡って略一定とするためには、熱交換器（２０）とスペアタイヤ（３０）とを略平行にすればよいが、熱交換器（２０）とスペアタイヤ（３０）とを略平行にすると、熱交換器（２０）を通過してスペアタイヤ（３０）に衝突した空気は、スペアタイヤ（３０）と略平行な全方向に拡がろうとするため、スペアタイヤ（３０）に衝突した空気同士が衝突し合うため、熱交換器（２０）の背面側における空気圧（静圧）が略全域に渡って上昇し、却って、熱交換器（２０）を通過する冷却風の風量が低下してしまうとともに、熱交換器（２０）を通過する冷却風の略全量を下方側外部に排出することが難しい。
【００１１】
これに対して、本発明では、スペアタイヤ（３０）の上端側と熱交換器（２０）の上端側との距離（Ｌ１）が、スペアタイヤ（３０）の下端側と熱交換器（２０）の下端側との距離（Ｌ２）より小さくなるように、熱交換器（２０）とスペアタイヤ（３０）とが配置されているので、熱交換器（２０）の背面側における空気圧（静圧）が上方側に向かうほど高くなることを抑制しながら、熱交換器（２０）を通過する冷却風の略全量を確実に下方側に転向させて外部に排出することができる。
【００１２】
したがって、熱交換器（２０）の上端側を通過する冷却風の風量が、熱交換器（２０）の下端側を通過する冷却風の風量に比べて小さくなってしまうことを抑制しながら、熱交換器（２０）を通過した空気を下方側に排出することができるので、熱交換器（２０）の放熱能力を十分に発揮させることができる。
【００１３】
請求項２に記載の発明では、熱交換器（２０）と熱交換器（２０）に空気を送風する送風機（１２）とは、車両に組み付ける前に互いに組み付けられて一部品された後、車両に組み付けられていることを特徴とするものである。

ラジエータ２０の背面側における空気圧を全域に渡って略一定とするためには、ラジエータ２０とスペアタイヤ３０とを略平行にすればよいが、ラジエータ２０とスペアタイヤ３０とを略平行にすると、ラジエータ２０を通過してスペアタイヤ３０に衝突した空気は、スペアタイヤ３０と略平行な全方向に拡がろうとするため、スペアタイヤ３０に衝突した空気同士が衝突し合うため、ラジエータ２０の背面側における空気圧（静圧）が略全域に渡って上昇し、却って、ラジエータ２０を通過する冷却風の風量が低下してしまうとともに、ラジエータ２０を通過する冷却風の略全量を下方側からトランクルーム４３外に排出することが難しい。
【００２６】
これに対して、本実施形態では、スペアタイヤ３０の上端側とラジエータ２０の上端側との距離Ｌ１が、スペアタイヤ３０の下端側とラジエータ２０の下端側との距離Ｌ２より小さくなるように、ラジエータ２０とスペアタイヤ３０とがトランクルーム４３内に末広がり状に配置されているので、ラジエータ２０の背面側における空気圧（静圧）が上方側に向かうほど高くなることを抑制しながら、ラジエータ２０を通過する冷却風の略全量を確実に下方側に転向させてトランクルーム４３外に排出することができる。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front end structure of a vehicle having a heat exchanger such as a radiator and a spare tire mounted on a front end side of the vehicle, the spare tire being disposed downstream of the heat exchanger in the air flow.
[0002]
[Prior art]
It is desirable that the cooling air that has passed through a heat exchanger mounted on the front end side of the vehicle, such as a radiator, be discharged to the outside of the trunk room from the lower side where the traveling wind flows.
[0003]
Conventionally, as shown in FIG. 2, in a state where the radiator 20 is arranged vertically, the upper end side of the spare tire 30 is inclined with respect to the vertical direction so as to be located on the vehicle front side from the lower end side. The cooling air that has passed through 20 is turned downward so as to collide with the spare tire 30, and is discharged out of the trunk room from below (for example, see Patent Document 1).
[0004]
[Patent Document 1]
Published Japanese Utility Model Application No. 6-75968
[Problems to be solved by the invention]
By the way, in the invention described in Patent Literature 1, since the radiator 20 is arranged substantially vertically, the spare tire 30 is inclined with respect to the vertical direction. The distance between 30 and radiator 20 is reduced.
[0006]
For this reason, the passage portion through which air diverted downward by collision with the spare tire 30 can flow, that is, the distance between the spare tire 30 and the radiator 20 becomes smaller toward the upper side, and the air pressure on the rear side of the radiator 20 becomes smaller. Becomes higher toward the upper side.
[0007]
For this reason, the amount of cooling air passing through the upper end of the radiator 20 is smaller than the amount of cooling air passing through the lower end of the radiator 20, so that the radiator 20 can exhibit its heat radiation capability sufficiently. difficult.
[0008]
SUMMARY OF THE INVENTION In view of the above points, the present invention firstly provides a novel front end structure of a vehicle different from the conventional one, and secondly, aims to sufficiently exert the capability of a heat exchanger such as a radiator. .
[0009]
[Means for Solving the Problems]
In order to achieve the above object, according to the first aspect of the present invention, the present invention is applied to a vehicle in which a heat exchanger (20) and a spare tire (30) are mounted on a front end side, and a spare tire (30) is provided. Is located downstream of the heat exchanger (20) in the airflow direction, and has a front end structure of a vehicle in which the upper side of a space (43) accommodating the heat exchanger (20) and the spare tire (30) is closed. The spare tire (30) is inclined with respect to the vertical direction such that the upper end is located forward of the vehicle from the lower end, and the heat exchanger (20) is located forward of the lower end of the heat exchanger (20). And the distance (L1) between the upper end of the spare tire (30) and the upper end of the heat exchanger (20) is equal to that of the lower end of the spare tire (30). Smaller than the distance (L2) from the lower end of the vessel (20) It is characterized in.
[0010]
By the way, in order to make the air pressure on the rear side of the heat exchanger (20) substantially constant over the entire area, the heat exchanger (20) and the spare tire (30) may be made substantially parallel. When the container (20) and the spare tire (30) are made substantially parallel, the air passing through the heat exchanger (20) and colliding with the spare tire (30) flows in all directions substantially parallel to the spare tire (30). Since the air colliding with the spare tire (30) collides with each other to expand, the air pressure (static pressure) on the rear side of the heat exchanger (20) rises over substantially the entire area, and on the contrary, heat exchange The amount of cooling air passing through the heat exchanger (20) is reduced, and it is difficult to discharge substantially the entire amount of cooling air passing through the heat exchanger (20) to the lower outside.
[0011]
On the other hand, in the present invention, the distance (L1) between the upper end of the spare tire (30) and the upper end of the heat exchanger (20) is equal to the distance between the lower end of the spare tire (30) and the heat exchanger (20). Since the heat exchanger (20) and the spare tire (30) are arranged so as to be smaller than the distance (L2) to the lower end of the heat exchanger, the air pressure (static pressure) on the back side of the heat exchanger (20) Of the cooling air passing through the heat exchanger (20) can be reliably turned to the lower side and discharged to the outside, while suppressing that the cooling air becomes higher toward the upper side.
[0012]
Therefore, while suppressing that the air volume of the cooling air passing through the upper end side of the heat exchanger (20) becomes smaller than the air volume of the cooling air passing through the lower end side of the heat exchanger (20), Since the air that has passed through the exchanger (20) can be discharged to the lower side, the heat radiation capability of the heat exchanger (20) can be sufficiently exhibited.
[0013]
According to the second aspect of the present invention, the heat exchanger (20) and the blower (12) for blowing air to the heat exchanger (20) are assembled to each other before being assembled to the vehicle, and are assembled into one part. It is characterized by being assembled in
[0014]
Incidentally, reference numerals in parentheses of the above-mentioned units are examples showing the correspondence with specific units described in the embodiments described later.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a perspective cross-sectional view showing a front end structure of a vehicle according to the present embodiment, in which a side member 10 is a beam-shaped strength member extending from a vehicle cabin (cabin) side to a front end side on a side of the vehicle. A heat exchanger such as a radiator 20 and a condenser 21 is attached to the side member 10, that is, a vehicle body via a carrier 11 at the tip end side of the side member 10.
[0016]
Here, the carrier is a vehicle to which at least a radiator 20 is fixed to a vehicle body at a front end portion of the vehicle and is referred to as a radiator support or a front end panel depending on a document.
[0017]
Note that the carrier 11 according to the present embodiment includes a beam-shaped upper member extending in the vehicle width direction above the vehicle front end, a beam-shaped lower member extending in the vehicle width direction below the vehicle front end, and the like. In the present embodiment, a fiber material having high tensile strength, such as carbon fiber or glass fiber, is integrally molded with a resin having increased strength.
[0018]
Incidentally, the radiator 20 cools the engine cooling water by exchanging heat between the engine cooling water and the outdoor air, and the condenser 21 is a radiator of a vapor compression refrigerator for an air conditioner, and includes an engine and a vapor compression refrigerator. The compressor is mounted on the rear side of the passenger compartment.
[0019]
The blower 12 blows cooling air to the radiator 20 and the condenser 21. In the present embodiment, the blower 12 is configured by an axial fan (see JIS B 0132 No. 1012, etc.) disposed downstream of the radiator 20 and the condenser 21 in the air flow. Have been. The fan shroud 13 prevents the wind induced by the blower 12 from flowing around the radiator 20.
[0020]
In the present embodiment, the blower 12 is fixed to the radiator 20 via the fan shroud 13, and the condenser 21 is fixed to the radiator 20 on the upstream side of the radiator 20 in the air flow, and the radiator 20, the condenser 21 and the blower 12 (including the fan shroud 13) are assembled to each other while being assembled to the vehicle body, that is, the carrier 11, and are assembled as one component (modularized) to the carrier 11.
[0021]
The spare tire 30 is an emergency tire. The spare tire 30 is housed in a trunk room 43 formed by a dashboard 41 and a hood 42 on the downstream side of the radiator 20 in the air flow. Incidentally, the dashboard 41 is a wall that separates the room from the outside, and the hood 42 is a lid that opens and closes an upper opening of the trunk room 43.
[0022]
The spare tire 30 is housed in the trunk room 43 in a state of being inclined with respect to the vertical direction such that the upper end is located on the front side of the vehicle from the lower end, and similarly, a modularized heat exchanger assembly such as the radiator 20 is provided. Also, it is stored in the trunk room 43 in a state where it is inclined with respect to the vertical direction so that the upper end side is located on the vehicle front side from the lower end side.
[0023]
The radiator 20 and the spare tire 30 are arranged such that the distance L1 between the upper end of the spare tire 30 and the upper end of the radiator 20 is smaller than the distance L2 between the lower end of the spare tire 30 and the lower end of the radiator 20. It is arranged in the trunk room 43 in a divergent shape.
[0024]
Next, the operation and effect of the present embodiment will be described.
[0025]
In order to make the air pressure on the rear side of the radiator 20 substantially constant over the entire area, the radiator 20 and the spare tire 30 may be made substantially parallel. However, when the radiator 20 and the spare tire 30 are made substantially parallel, the radiator The air that has passed through the tire 20 and collided with the spare tire 30 tends to spread in all directions substantially parallel to the spare tire 30, and the air that collided with the spare tire 30 collide with each other. The air pressure (static pressure) rises over substantially the entire area, and on the contrary, the flow rate of the cooling air passing through the radiator 20 decreases, and almost the entire amount of the cooling air passing through the radiator 20 is discharged from the lower side to the outside of the trunk room 43. Difficult to discharge.
[0026]
In contrast, in the present embodiment, the distance L1 between the upper end of the spare tire 30 and the upper end of the radiator 20 is smaller than the distance L2 between the lower end of the spare tire 30 and the lower end of the radiator 20. Since the radiator 20 and the spare tire 30 are arranged in a flared shape in the trunk room 43, the radiator 20 and the spare tire 30 pass through the radiator 20 while suppressing the air pressure (static pressure) on the rear side of the radiator 20 from increasing toward the upper side. Almost the entire amount of the cooling air to be turned can be reliably turned downward and discharged out of the trunk room 43.
[0027]
Therefore, while suppressing that the air volume of the cooling air passing through the upper end side of the radiator 20 becomes smaller than the air volume of the cooling air passing through the lower end side of the radiator 20, the air flowing through the radiator 20 is moved downward. The radiator 20 can sufficiently exhibit the heat radiation capability.
[0028]
In order to sufficiently exert the above-described effects, the angle θ1 between the spare tire 30 and the vertical direction is set to 15 ° or more and 25 ° or less (20 ° in the present embodiment), and the radiator 20 and the vertical direction It is desirable that the angle θ2 formed is 3 ° or more and 15 ° or less (5 ° in the present embodiment).
[0029]
(Other embodiments)
In the above-described embodiment, the fan shroud 13 and the carrier 11 are separate bodies. However, the present invention is not limited to this. For example, the two members 13 and 11 may be integrally formed of resin.
