【考案の詳細な説明】
本考案は、自動車用合成樹脂製ファンシュラウドに関す
るものである。[Detailed Description of the Invention] The present invention relates to a synthetic resin fan shroud for automobiles.
詳しく述べると、リング部が高い剛性を有する自動車用
合成樹脂性ファンシュラウドに関するものである。More specifically, the present invention relates to a synthetic resin fan shroud for an automobile whose ring portion has high rigidity.
この種の自動車用ファンシュラウドは、一般に、自動車
のラジェータに取付られ、該ラジェータを冷却するため
の冷却風を起すファンがその内周面に設置されるリング
部と、前記ファンによる冷却風をラジェータ筐で案内す
る傾斜部とを有する。This type of automotive fan shroud is generally attached to a radiator of an automobile, and includes a ring portion on the inner circumferential surface of which is installed a fan that generates cooling air to cool the radiator, and a ring portion that generates cooling air to cool the radiator. and an inclined part guided by the housing.
しかして、このような自動車のラジェータに取付られる
ファンシュラウドは、そのリング部が一重壁であるため
、合成樹脂製ファンシュラウドは鉄製シュラウドに比較
して種々の利点を有しているにもかかわらず剛性が低い
ので、つぎのような問題点がある。However, since the ring part of the fan shroud installed in the radiator of such a car is a single wall, although synthetic resin fan shrouds have various advantages compared to iron shrouds, Since the rigidity is low, there are the following problems.
すなわち従来のファンは、（１）成形直後の冷却時の歪
変形、（２）製品在庫時の経時歪による変形、（３）輸
送時の振動、抑圧等による変形、（４）ラジェータに取
付けて使用される時の繰り返し熱変動による変形、（５
）外力（使用時の車の振動による力等）による変形など
のために、リング部の真円度を損ない、ファンとの干渉
を招ぐおそれがある。In other words, conventional fans suffer from (1) distortion deformation during cooling immediately after molding, (2) deformation due to aging distortion during product inventory, (3) deformation due to vibration, suppression, etc. during transportation, and (4) deformation when installed on a radiator. Deformation due to repeated thermal fluctuations during use, (5
) Due to deformation due to external forces (forces caused by car vibrations during use, etc.), the roundness of the ring part may be impaired and there is a risk of interference with the fan.
このため、従来のファンとリング部との間のギャップを
大きくせざるを得す、ファンの吸込み風量に悪影響を及
ぼす欠点を有している。For this reason, the gap between the conventional fan and the ring portion has to be increased, which has the disadvantage of adversely affecting the amount of air sucked into the fan.
本考案は、前記のごとき従来の自動車用合成樹脂製ファ
ンシュラウドの諸欠点を改善するためになされたもので
、自動車用合成樹脂製ファンシュラウドのリング部を一
定間隔で二重のリング壁により構成してなるファンシュ
ラウドである。The present invention was developed to improve the various drawbacks of the conventional synthetic resin fan shroud for automobiles as described above. This is a fan shroud.
つぎに、図面を参照しながら本考案を詳細に説明する。Next, the present invention will be explained in detail with reference to the drawings.
すなわち、第１〜２図に示すように、合成樹脂製の自動
車用ファンシュラウド１のリング部に、該ファンシュラ
ウド１の傾斜部２の端部から外側リング３を連設する。That is, as shown in FIGS. 1 and 2, an outer ring 3 is connected to a ring portion of an automobile fan shroud 1 made of synthetic resin from an end of an inclined portion 2 of the fan shroud 1.
該外側リング３の内側には、一定間隔をおいて内側リン
グ４を設け、該内側リング４の下部は外側リング３の下
部、すなわち前記ファンシュラウド１の傾斜部２の端部
とブリッジ５により連結されている。Inside the outer ring 3, an inner ring 4 is provided at regular intervals, and the lower part of the inner ring 4 is connected to the lower part of the outer ring 3, that is, the end of the sloped part 2 of the fan shroud 1, by a bridge 5. has been done.
そして、このように構成される二重リングは、合成樹脂
製のファンシュラウド１の成形時に一体的に形成される
。The double ring configured in this manner is integrally formed when the fan shroud 1 made of synthetic resin is molded.
さらに、本考案に係るファンシュラウド１は、第３図に
示すように、リング部の外側リング３と内側リング４と
の間に、両リング内壁に達するように波形のリプ６を設
けてなるもので、これにより二重リング分はさらに補強
される。Furthermore, as shown in FIG. 3, the fan shroud 1 according to the present invention has a corrugated lip 6 between the outer ring 3 and the inner ring 4 of the ring portion so as to reach the inner walls of both rings. This further strengthens the double ring.
寸た、第４図は、本考案の他の実施態様を示すもので、
リング部の外側リング３と内側リング４とのあいだに両
リング内壁に達するように放射状にリブ６を適当数設け
てなるもので、これにより二重リング部はさらに補強さ
れる。Figure 4 shows another embodiment of the present invention.
An appropriate number of ribs 6 are provided radially between the outer ring 3 and inner ring 4 of the ring portion so as to reach the inner walls of both rings, thereby further reinforcing the double ring portion.
さらに、第５図は、本考案の別の実施態様を示すもので
、リング部を全周にわたって二重壁にするのでなく、外
側リング３は部分的に設け、必要により外側リング３と
内側リング４との間にリプ６を設けてなるものであり、
このような構成によっても充分な補強効果は得られる。Furthermore, FIG. 5 shows another embodiment of the present invention, in which the outer ring 3 is partially provided instead of having a double wall over the entire circumference, and if necessary, the outer ring 3 and the inner ring It is formed by providing a lip 6 between 4 and 4,
A sufficient reinforcing effect can also be obtained with such a configuration.
以上述べたように本考案による自動車用合成樹脂製ファ
ンシュラウドは、リング部が一定間隔で二重のリング壁
により構成され、この二重リング壁の間に複数のリブを
設けたので、リング部の剛性が極めて大きくなり、この
ため、成形直後の冷却時の歪変形、製品在庫時の経時歪
による変形、輸送時の振動、押圧等による歪変形、ラジ
ェータに取付けられて使用される時の繰り返し熱変動に
よる歪変形、外力（車の振動等による力）による変形な
どが大幅に減少する。As described above, in the synthetic resin fan shroud for automobiles according to the present invention, the ring portion is composed of double ring walls at regular intervals, and a plurality of ribs are provided between the double ring walls. The rigidity of the product becomes extremely large, and this causes distortion and deformation during cooling immediately after molding, deformation due to aging over time during product inventory, deformation due to vibration and pressure during transportation, and repeated use when attached to a radiator. Strain and deformation caused by thermal fluctuations and deformation caused by external forces (forces caused by vehicle vibrations, etc.) are significantly reduced.
したがってファンシュラウドのリング部とファンとの間
の隙間を従来の自動車用合成樹脂製ファンシュラウドよ
り小さく好適なものに保ち得るので、ファン動車が向上
する。Therefore, the gap between the ring portion of the fan shroud and the fan can be kept smaller and more suitable than in conventional synthetic resin fan shrouds for automobiles, thereby improving the performance of the fan-driven vehicle.
オた、前記二重リング壁やリブはファンシュラウドの成
形時に一体成形することができるので極めて安価である
。Additionally, the double ring wall and ribs can be integrally molded during molding of the fan shroud, so they are extremely inexpensive.
