Description
【０００１】[0001]
本考案は、内燃機関の冷却装置に関し、より詳しくは冷却ファンのファンガイ ドに関する。 The present invention relates to a cooling device for an internal combustion engine, and more particularly to a fan guide for a cooling fan.
【０００２】[0002]
図２に従来の内燃機関の冷却装置を示し、機関本体１の前方に冷却ファン２が 配置されており、さらにその前方にラジエータ３が配置されている。冷却ファン ２のファンブレード４の外周にはラジエータ３により支持されたファンシュラウ ド５が設けられており、また機関本体１の前部にはファンプーリ６、クランクプ ーリ７、ウォータポンププーリ８が設けられている。 FIG. 2 shows a conventional cooling device for an internal combustion engine, in which a cooling fan 2 is arranged in front of the engine body 1 and a radiator 3 is arranged in front of it. A fan shroud 5 supported by a radiator 3 is provided on the outer periphery of a fan blade 4 of the cooling fan 2, and a fan pulley 6, a crank pulley 7, a water pump pulley 8 are provided at the front of the engine body 1. Is provided.
【０００３】 ファン２が回転すると冷却風がラジエータ３を経て矢印イ、ロで示す機関本体 １側に流れて機関を冷却する。When the fan 2 rotates, cooling air flows through the radiator 3 to the engine body 1 side indicated by arrows a and b to cool the engine.
【０００４】[0004]
ところで、上記の従来の内燃機関の冷却装置においては、冷却ファン２の吐出 側にはファンガイドがなく、冷却ファン２を通過した冷却風は図２で示す矢印ロ に示すように、機関本体１の前面に直交する方向に流れ、一方、機関本体１の前 面には各種のプーリ６、７、８がランダムに設けてあるため、ファンの吐出抵抗 が大きく、ファン性能が有効に使われていない。 By the way, in the above-described conventional cooling apparatus for an internal combustion engine, there is no fan guide on the discharge side of the cooling fan 2, and the cooling air passing through the cooling fan 2 is the engine body 1 as shown by the arrow B in FIG. Flow in a direction orthogonal to the front surface of the engine, while various pulleys 6, 7 and 8 are randomly provided on the front surface of the engine body 1, so the discharge resistance of the fan is large and the fan performance is used effectively. Absent.
【０００５】 そこで、実開昭５９−１０３８２２号公報、実開昭６３−１９３７２６号公報 、実開平１−７１１３３号公報に見られるように、冷却ファンの吐出側にファン ガイドを設けて、冷却ファンを通過した冷却風を径方向に案内して冷却ファンの 吐出抵抗の低減を図ろうとするものが提案されている。Therefore, as seen in Japanese Utility Model Laid-Open No. 59-103822, Japanese Utility Model Laid-Open No. 63-193726, and Japanese Utility Model Laid-Open No. 1-71133, a cooling fan is provided with a fan guide on the discharge side. It has been proposed to guide the cooling air that has passed through the fan in the radial direction to reduce the discharge resistance of the cooling fan.
【０００６】 しかしながら、それ等のものは、ファンガイドをファンブレードの外周部にリ ング状に設置したもの、ファンガイドとして上方に延びる板状のものを用いたも の、ファンガイドをファンブレードの内円周寄りに設置したものであるため、吐 出風の整流効果は不充分であり、さらに吐出抵抗を低減させることはできない。 また、いずれのものも、ファンガイドの具体的な支持手段については開示されて いない。[0006] However, in such a device, a fan guide is installed on the outer peripheral portion of the fan blade in a ring shape, and a plate-shaped one extending upward is used as the fan guide. Since it is installed near the inner circumference, the rectification effect of the discharged air is insufficient and the discharge resistance cannot be further reduced. Moreover, none of them discloses specific support means for the fan guide.
【０００７】 したがって、本考案の目的とするところは、一つには従来のものに比べて充分 な整流効果を発揮して吐出抵抗の低減を図り、ファン風量を増大するファンガイ ドを備えた内燃機関の冷却装置を提供するにあり、他の一つはファンガイドを簡 単な手段で支持することのできる内燃機関の冷却装置を提供すべくなされたもの である。Therefore, one of the objects of the present invention is to provide a fan guide that exhibits a sufficient rectifying effect as compared with the conventional one to reduce the discharge resistance and increase the fan air volume. Another object of the present invention is to provide a cooling device for an internal combustion engine, and the other is to provide a cooling device for an internal combustion engine that can support a fan guide by a simple means.
【０００８】[0008]
このため、本考案によれば、機関本体の前方に冷却ファンを、さらにその前方 にラジエータをそれぞれ配置し、ファンにより冷却風をラジエータを経て機関本 体側に吸引して機関を冷却する内燃機関の冷却装置において、冷却ファンと機関 本体の前部との間に、機関本体側が大径をなす円錐状であって、少なくともファ ンブレードの内円周と外円周とで囲まれた面積相当の整流板を設け、該整流板を 冷却ファンまたはファンプーリと一体で回転するように設けてなる内燃機関の冷 却装置が提供される。 Therefore, according to the present invention, a cooling fan is arranged in front of the engine body, and a radiator is arranged in front of the cooling fan, and the cooling air is sucked by the fan to the engine main body side through the radiator to cool the engine. In a cooling device, between the cooling fan and the front part of the engine body, there is a rectification of a conical shape with a large diameter on the engine body side and at least the area surrounded by the inner and outer circumferences of the fan blade. There is provided a cooling device for an internal combustion engine, which is provided with a plate and the straightening plate is provided so as to rotate integrally with a cooling fan or a fan pulley.
【０００９】[0009]
冷却ファンが回転すると冷却風がラジエータを経て機関本体側に流れる。その 際、整流板も冷却ファンと共に回転し、冷却ファンを通過した冷却風は整流板上 を径方向外方に滑らかに案内され、冷却ファンの吐出抵抗は低減する。 When the cooling fan rotates, cooling air flows through the radiator toward the engine body. At that time, the straightening vane also rotates together with the cooling fan, and the cooling air passing through the cooling fan is smoothly guided radially outward on the straightening vane, and the discharge resistance of the cooling fan is reduced.

以下、図面を参照して本考案の実施例を説明する。 Embodiments of the present invention will be described below with reference to the drawings.
【００１１】 図１において、冷却ファン２と機関本体１の前部との間に整流板９が設けられ ており、この整流板９は機関本体１側が大径をなす円錐状であって、少なくとも ファンブレード４の内円周と外円周とで囲まれた面積相当のものである。なお、 整流板９はファンブレード４の外円周以上のものであってもよい。そして、整流 板９は冷却ファン２と一体で回転するように設けられている。なお、整流板９は ファンプーリ６と一体で回転するように設けてもよい。In FIG. 1, a rectifying plate 9 is provided between the cooling fan 2 and the front part of the engine body 1. The rectifying plate 9 has a conical shape with a large diameter on the engine body 1 side, and at least It corresponds to the area surrounded by the inner circumference and the outer circumference of the fan blade 4. The straightening vane 9 may be larger than the outer circumference of the fan blade 4. The current plate 9 is provided so as to rotate integrally with the cooling fan 2. The current plate 9 may be provided so as to rotate integrally with the fan pulley 6.
【００１２】 冷却ファン２が回転すると冷却風がラジエータ３を経て機関本体１側へ流れる 。その際、整流板９も冷却ファン２と共に回転し、冷却ファン２を通過した冷却 風は整流板９上を径方向外方に滑らかに案内され、これにより冷却ファンの吐出 抵抗は低減し、ファン風量が増大する。When the cooling fan 2 rotates, cooling air flows through the radiator 3 to the engine body 1 side. At that time, the straightening vane 9 also rotates together with the cooling fan 2, and the cooling air having passed through the cooling fan 2 is smoothly guided radially outward on the straightening vane 9, whereby the discharge resistance of the cooling fan is reduced, and the fan is cooled. The air volume increases.
【００１３】[0013]
整流板は、機関本体側が大径をなす円錐状であって、少なくともファンブレー ドの内円周と外円周とで囲まれた面積相当の面積を有するものであるので、充分 な整流効果を発揮して吐出抵抗の低減を図り、この結果、ファン風量を増加し、 ラジエータの冷却効果を大きくすることができる。また、整流板は冷却ファンと 共に、回転するが整流効果には支障を来すことなく、整流板を確実に支持する。 The current plate has a conical shape with a large diameter on the engine body side and has an area equivalent to at least the area surrounded by the inner circumference and the outer circumference of the fan blade. By exerting the effect, the discharge resistance can be reduced, and as a result, the fan air volume can be increased and the radiator cooling effect can be increased. Further, the straightening vane rotates together with the cooling fan, but does not hinder the straightening effect and reliably supports the straightening vane.
