【発明の詳細な説明】
本発明は自動車の車体構造に関し、特に、エン
ジンルーム中へ冷却風を取入れるための構造に関
する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile body structure, and more particularly to a structure for introducing cooling air into an engine compartment.
最近、エンジンに対するターボ過給機の付加等
が原因となつて、自動車のエンジンルーム内の発
熱量が急速に増加しており、エンジンルームの冷
却が問題にされつつある。 Recently, due to the addition of a turbocharger to an engine, the amount of heat generated in the engine compartment of an automobile has been rapidly increasing, and cooling of the engine compartment is becoming a problem.
ところで、従来のエンジンルームにおいては、
第１図示のようにラジエータコア１の後部に導風

ンルームＡ内の機器を充分に冷却することが困難
である。 By the way, in the conventional engine room,
As shown in the first figure, an air guide shroud 2 is attached to the rear of the radiator core 1, and a fan 3 arranged at the rear of the air guide shroud 2 takes outside air into the engine room A through the radiator core 1. The equipment in A is being cooled. However, in such a configuration, the outside air is used as cooling air after passing through the radiator core 1.
Since the radiator core 1 is already heated, it is difficult to sufficiently cool the equipment in the engine room A.
本発明は、以上に述べたような従来の冷却風取

外気を、冷却風の一部として利用できる構造を得

して利用することを提案するものである。 In view of the actual state of the conventional cooling air intake structure as described above, the present invention aims to provide a structure in which outside air that does not pass through the radiator core can be used as part of the cooling air. It is proposed that a part of the fan attached to the core protrudes outward from the periphery of the radiator core, so that outside air that does not pass through the radiator core is directly guided into the engine room and used as part of the cooling air.
以下、第２図から第４図について本発明の実施
例の詳細を説明する。 Embodiments of the present invention will now be described in detail with reference to FIGS. 2 to 4.

気は、従来に比較して充分に冷却効果のある冷却
風として利用でききる。 Figures 2 and 3 show two electric fans 3A, 3.
This is an example in which cooling air is sucked using B.
The lateral width L 1 of the air guide shroud 2A of the electric fans 3A, 3B is sufficiently larger than the lateral width L 2 of the radiator core 1. In other words, according to the present invention, the left and right intake ends 2 of the wind guide shroud 2A
a and 2b are opened on the left and right sides of the radiator core 1, so that outside air can be directly taken in from the left and right intake ends 2a and 2b. Therefore, according to such a structure, the low-temperature outside air taken in from the left and right intake ends 2a, 2b of the wind guide shroud 2A can be used as cooling air that has a more sufficient cooling effect than in the past.

る。 FIG. 4 shows an example in which the present invention is applied to push-in electric fans 3C, 3D, and the electric fans 3C, 3D and air guide shroud 2B in this embodiment are arranged at the front of the radiator core 1. The left and right discharge ends 2c and 2d of the air guide shroud 2B are opened toward the engine room A at positions outward from the left and right ends of the radiator core 1, so that they are not pushed out by the electric fans 3C and 3D. A part of the outside air flows directly into the engine room A without passing through the radiator core 1. Therefore, even with such a structure, the cooling effect in the engine room A can be improved as in the case of FIGS. 2 and 3.
尚、以上の実施例では電動フアンを２つ用いた
例を示したが、フアンの数、駆動手段は任意に選
択でき、またシユラウドも無くても良い。更に、
フアンの突出部からエンジン補機の特に冷却を要

を延設するようにしても良い。 Incidentally, in the above embodiment, an example was shown in which two electric fans were used, but the number of fans and the driving means can be arbitrarily selected, and the shroud may also be omitted. Furthermore,
A duct 4 runs from the protruding part of the fan to the parts of the engine auxiliary equipment that require particular cooling, as shown by the imaginary line in Figure 4.
You may also extend it.
以上の説明から明らかなように、本発明によれ

コアとフアンとの関係を変更するだけで、エンジ

安価な構造でエンジンルーム内の発熱量増加に充
分に対応できる。 As is clear from the above description, according to the present invention, the cooling effect in the engine compartment can be improved by simply changing the relationship between the radiator core and the fan without adding any new parts. The structure is inexpensive and can sufficiently cope with the increase in heat generation in the engine room.
