Description

本発明は、熱交換ユニットを構成する冷却ファン装置に関する。   The present invention relates to a cooling fan device constituting a heat exchange unit.

従来から、車両のフロントエンドモジュールには、熱交換ユニットが設けられている。この熱交換ユニットは、ラジエータ及びコンデンサからなる熱交換器と、電動ファン及びファンモータなどからなる冷却ファン装置とによって大略構成されている（例えば、特許文献１参照）。   Conventionally, a heat exchange unit is provided in a front end module of a vehicle. This heat exchange unit is roughly configured by a heat exchanger composed of a radiator and a condenser, and a cooling fan device composed of an electric fan, a fan motor, and the like (see, for example, Patent Document 1).

熱交換器の後部には、熱交換器と電動ファンとの間の流路を形成するシュラウドが設けられている。シュラウドには、正面視で略円形状の左右一対の開口部が形成されており、該開口部には、電動ファンが取り付けられている。   A shroud that forms a flow path between the heat exchanger and the electric fan is provided at the rear of the heat exchanger. The shroud is formed with a pair of left and right openings that are substantially circular in a front view, and an electric fan is attached to the openings.

このような熱交換ユニットでは、電動ファンの回転によって、車両前部から導入した空気を熱交換器に通過させ、熱交換器内を循環する冷媒や冷却水を放熱させて冷却できるようになっている。   In such a heat exchange unit, rotation of the electric fan allows air introduced from the front of the vehicle to pass through the heat exchanger and dissipates the refrigerant and cooling water circulating in the heat exchanger to cool the air. Yes.

特開２００５−８３３２１号公報JP 2005-83321 A

しかしながら、上述した従来の冷却ファン装置では、シュラウドに形成された開口部が略円形状であることによって、該開口部の周囲の壁部（特に、正面視で四隅）に空気が通過しにくい。つまり、熱交換器の端部（特に、正面視で四隅）に空気が通過しにくいのが現状であった。このため、熱交換器の全域に空気流を通過させて、熱交換器における熱交換の効率をより向上させる技術が望まれていた。   However, in the above-described conventional cooling fan device, since the opening formed in the shroud has a substantially circular shape, it is difficult for air to pass through walls around the opening (particularly, four corners in front view). In other words, the current situation is that air does not easily pass through the end portions of the heat exchanger (particularly, four corners in front view). For this reason, the technique which passes an air flow through the whole region of a heat exchanger and improves the efficiency of the heat exchange in a heat exchanger was desired.

そこで、本発明は、熱交換器の全域に空気流を通過させ、熱交換器における熱交換の効率を向上できる冷却ファン装置の提供を目的とする。   Therefore, an object of the present invention is to provide a cooling fan device that allows an air flow to pass through the entire heat exchanger and improves the efficiency of heat exchange in the heat exchanger.

上述した課題を解決するため、本発明は、次のような特徴を有している。まず、本発明の第１の特徴は、車両前部側に配設される熱交換器に空気を送風する冷却ファン装置であって、送風機と、前記熱交換器の前部に配設されて前記送風機から送られる空気を前記熱交換器に向けて吹き付ける空気案内器とを備え、前記空気案内器は、前記熱交換器の車幅方向の側部に配設され、前記送風機から送られる空気が送られる側部ダクトと、前記熱交換器の前部で前記車幅方向に沿って前記熱交換器の全面に対応して車両上下方向に複数段に配設され、前記側部ダクトと連通する前部ダクトと、複数段の前記前部ダクトの間に立設される板状の案内板とによって構成され、前記前部ダクトには、前記側部ダクトから送られた空気を前記熱交換器に向けて吹き付けるエジェクタノズルが形成され、前記案内板は、前記車幅方向に対して所定間隔おきに設けられて、前記エジェクタノズルから吹き出された空気を前記熱交換器へ案内することを要旨とする。   In order to solve the above-described problems, the present invention has the following features. First, a first feature of the present invention is a cooling fan device that blows air to a heat exchanger disposed on the front side of a vehicle, the fan being disposed at a front portion of the blower and the heat exchanger. An air guide that blows air sent from the blower toward the heat exchanger, and the air guide is disposed on a side of the heat exchanger in the vehicle width direction and is sent from the blower Are arranged in a plurality of stages in the vehicle vertical direction corresponding to the entire surface of the heat exchanger along the vehicle width direction at the front portion of the heat exchanger, and communicated with the side duct. And a plate-shaped guide plate erected between the front ducts in a plurality of stages. In the front duct, the air sent from the side duct is exchanged with the heat. An ejector nozzle that blows toward the container is formed, and the guide plate It provided every other predetermined interval, and summarized in that for guiding the air blown out from the ejector nozzle to the heat exchanger against.

本発明の第２の特徴は、本発明の第１の特徴に係る冷却ファン装置であって、前記前部ダクトは、前記熱交換器に向けて延在する本体部と、前記本体部の前部に設けられる先端部とを備え、前記本体部は、前記車幅方向に対して所定間隔おきに設けられて前記先端部が取り付けられる基台を有し、前記案内板は、前記基台上に設けられることを要旨とする。   A second feature of the present invention is the cooling fan device according to the first feature of the present invention, wherein the front duct includes a main body extending toward the heat exchanger, and a front of the main body. A front end portion provided at a portion, and the main body portion includes a base provided at predetermined intervals with respect to the vehicle width direction to which the front end portion is attached, and the guide plate is mounted on the base The main point is that it is provided.

本発明の第３の特徴は、本発明の第１又は第２の特徴に係る冷却ファン装置であって、前記案内板の前記車幅方向に沿った幅は、前記熱交換器に向かって細くなるように形成されることを要旨とする。   A third feature of the present invention is the cooling fan device according to the first or second feature of the present invention, wherein a width of the guide plate along the vehicle width direction is narrower toward the heat exchanger. The gist is to be formed as follows.

本発明の第４の特徴は、本発明の第１乃至第３の特徴に係る冷却ファン装置であって、前記案内板の前記車両上下方向に沿った高さは、前記熱交換器に向かって高くなるように形成されることを要旨とする。   A fourth feature of the present invention is the cooling fan device according to the first to third features of the present invention, wherein the height of the guide plate along the vehicle vertical direction is toward the heat exchanger. The gist is that it is formed to be higher.

本発明の特徴によれば、前部ダクトは、熱交換器の前部で車幅方向に沿って熱交換器の全面に対応して車両上下方向に複数段に配設され、前部ダクトに形成されたエジェクタノズルは、側部ダクトから送られた空気を熱交換器に向けて吹き付ける。これにより、エジェクタノズルから放出された空気は、前部ダクトの前部の空気を誘引しながら熱交換器を通過する。つまり、エジェクタノズルから放出された空気は、当該空気に誘引された前部ダクトの前部の空気とともに、熱交換器の全面を通過する。このため、熱交換器の全面を確実に冷却でき、熱交換器における熱交換の効率をより向上できる。   According to the feature of the present invention, the front duct is arranged in a plurality of stages in the vehicle vertical direction corresponding to the entire surface of the heat exchanger along the vehicle width direction at the front of the heat exchanger. The formed ejector nozzle blows air sent from the side duct toward the heat exchanger. Thereby, the air discharged | emitted from the ejector nozzle passes a heat exchanger, attracting the air of the front part of a front duct. That is, the air discharged from the ejector nozzle passes through the entire surface of the heat exchanger together with the air in the front part of the front duct attracted by the air. For this reason, the whole surface of a heat exchanger can be cooled reliably and the efficiency of heat exchange in a heat exchanger can be improved more.

加えて、案内板は、エジェクタノズルから吹き出された空気を熱交換器へ案内する。つまり、エジェクタノズルから放出された空気は、コアンダ効果により案内板に沿って送風される。これにより、案内板に沿った空気は、熱交換器に向かうに連れて除々に前部ダクトから離れるように流れる。従って、熱交換器を通過する際の空気の風速分布が均等になりやすく、熱交換器の全面をさらに確実に冷却できる。   In addition, the guide plate guides the air blown from the ejector nozzle to the heat exchanger. That is, the air discharged from the ejector nozzle is blown along the guide plate by the Coanda effect. Thereby, the air along the guide plate gradually flows away from the front duct as it goes to the heat exchanger. Therefore, the air velocity distribution when passing through the heat exchanger tends to be uniform, and the entire surface of the heat exchanger can be cooled more reliably.

その上、案内板は、車幅方向に対して所定間隔おきに設けられる。これにより、案内板により前部ダクトの間を支持することができ、前部ダクトの剛性を確保できる。   In addition, the guide plates are provided at predetermined intervals in the vehicle width direction. Thereby, between the front ducts can be supported by the guide plate, and the rigidity of the front ducts can be ensured.

（熱交換ユニットの組立方法）
次に、上述した熱交換ユニット１の組立方法について、図面を参照しながら簡単に説明する。 (Assembling method of heat exchange unit)
Next, a method for assembling the heat exchange unit 1 will be briefly described with reference to the drawings.

まず、側部ダクト１１０の取付部１１３に前部ダクト１２０を取り付けて、前部ダクト１２０に案内板１４０を取り付けることによって、空気案内器１００を形成する。なお、案内板１４０については、前部ダクト１２０が側部ダクト１１０に取り付けられる前に前部ダクト１２０に取り付けられてもよく、前部ダクト１２０に固定されればよい。   First, the air duct 100 is formed by attaching the front duct 120 to the attachment portion 113 of the side duct 110 and attaching the guide plate 140 to the front duct 120. The guide plate 140 may be attached to the front duct 120 before the front duct 120 is attached to the side duct 110 or may be fixed to the front duct 120.

次いで、図２〜図４に示すように、ラジエータコアサポート３０に、熱交換器１０や送風機２１、空気案内器１００、ライト（不図示）を組み付けて熱交換ユニット１を組み立てる。つまり、熱交換器収容部３１に熱交換器１０を組み付け、ダクト収容部３２に空気案内器１００を組み付け、送風機収容部３３に送風機２１を組み付け、ライト収容部３４にライト（不図示）を組み付ける。   Next, as shown in FIGS. 2 to 4, the heat exchanger 10, the blower 21, the air guide 100, and the light (not shown) are assembled to the radiator core support 30 to assemble the heat exchange unit 1. That is, the heat exchanger 10 is assembled in the heat exchanger housing 31, the air guide 100 is assembled in the duct housing 32, the blower 21 is assembled in the blower housing 33, and a light (not shown) is assembled in the light housing 34. .

この際、ダクト収容部３２の係止突起３２Ａに側部ダクト１１０の係止凹部１１４が圧入されることによって、空気案内器１００がラジエータコアサポート３０に係止されるとともに熱交換器１０の前部に配設される。   At this time, the air guide 100 is locked to the radiator core support 30 and the front of the heat exchanger 10 by press-fitting the locking recess 114 of the side duct 110 into the locking protrusion 32A of the duct housing portion 32. Arranged in the section.

（空気の流れ）
次に、上述した熱交換ユニット１の空気の流れについて、図面を参照しながら簡単に説明する。図６は、本実施形態に係る前部ダクト１２０と比較するための図であり、図６（ａ）は、案内板１４０が設けられていない空気案内器の前部ダクトを示す断面図であり、図６（ｂ）は、案内板１４０が設けられた空気案内器１００の前部ダクト１２０示す断面図である。 (the flow of air)
Next, the air flow of the heat exchange unit 1 described above will be briefly described with reference to the drawings. FIG. 6 is a view for comparison with the front duct 120 according to the present embodiment, and FIG. 6A is a cross-sectional view showing the front duct of the air guide where the guide plate 140 is not provided. FIG. 6B is a cross-sectional view showing the front duct 120 of the air guide 100 provided with the guide plate 140.

まず、送風機２１が駆動すると、送風機２１から側部ダクト１１０へ空気が送り込まれる。側部ダクト１１０へ送り込まれた空気は、側部ダクト１１０の各取付部１１３から分岐して前部ダクト１２０に導入される。なお、送風機２１の回転速度等を調整することによって空気の速度を制御できる。   First, when the blower 21 is driven, air is sent from the blower 21 to the side duct 110. The air fed into the side duct 110 is branched from each mounting portion 113 of the side duct 110 and introduced into the front duct 120. The air speed can be controlled by adjusting the rotational speed of the blower 21 and the like.

そして、前部ダクト１２０に導入された空気は、前部ダクト１２０内を通過してエジェクタノズル１３０から熱交換器１０に対して送風される（図４参照）。エジェクタノズル１３０から放出された空気は、前部ダクト１２０の前部の空気を誘引する（巻き込む）とともに、コアンダ効果によって案内板１４０に沿って送風される。つまり、エジェクタノズル１３０から放出された空気は、当該空気に誘引された前部ダクト１２０の前部の空気とともに、案内板１４０に案内されながら熱交換器１０の全面を通過している。   Then, the air introduced into the front duct 120 passes through the front duct 120 and is blown from the ejector nozzle 130 to the heat exchanger 10 (see FIG. 4). The air discharged from the ejector nozzle 130 attracts (involves) the air in the front portion of the front duct 120 and is blown along the guide plate 140 by the Coanda effect. That is, the air discharged from the ejector nozzle 130 passes through the entire surface of the heat exchanger 10 while being guided by the guide plate 140 together with the air in the front portion of the front duct 120 attracted by the air.

ところで、案内板１４０が設けられていない場合、本体部１２１の連結基台１２３上では、エジェクタノズル１３０から放出された空気が通過しなくなっており、加えて、各前部ダクト１２０の中間の風速が遅くなっている。従って、図６（ａ）に示すように、案内板１４０が設けられていない場合、熱交換器１０を通過する際の空気の風速分布が均等になりにくくなっている。   By the way, when the guide plate 140 is not provided, the air discharged from the ejector nozzle 130 does not pass on the connection base 123 of the main body 121, and in addition, an intermediate wind speed between the front ducts 120. Is slow. Therefore, as shown in FIG. 6A, when the guide plate 140 is not provided, the wind speed distribution of air when passing through the heat exchanger 10 is difficult to be uniform.

これに対して、本実施形態では、本体部１２１の連結基台１２３上には、先細状の案内板１４０が設けられている。これにより、エジェクタノズル１３０から放出された空気は、上述したように、コアンダ効果によって案内板１４０に沿って送風される。つまり、図６（ｂ）に示すように、案内板１４０に沿った空気は、熱交換器１０に向かうに連れて除々に前部ダクト１２０から離れるように流れる。従って、熱交換器１０を通過する際の空気の風速分布が均等になりやすくなる。   On the other hand, in the present embodiment, a tapered guide plate 140 is provided on the connection base 123 of the main body 121. Thereby, the air discharged from the ejector nozzle 130 is blown along the guide plate 140 by the Coanda effect as described above. That is, as shown in FIG. 6B, the air along the guide plate 140 gradually flows away from the front duct 120 toward the heat exchanger 10. Therefore, the air velocity distribution when passing through the heat exchanger 10 is likely to be uniform.

（作用・効果）
以上説明した本実施形態では、前部ダクト１２０は、熱交換器１０の前部で車幅方向に沿って熱交換器１０の全面に対応して車両上下方向に複数段に配設され、前部ダクト１２０に形成されたエジェクタノズル１３０は、側部ダクト１１０から送られた空気を熱交換器１０に向けて吹き付ける。これにより、エジェクタノズル１３０から放出された空気は、前部ダクト１２０の前部の空気を誘引しながら熱交換器１０を通過する。つまり、エジェクタノズル１３０から放出された空気は、当該空気に誘引された前部ダクト１２０の前部の空気とともに、熱交換器１０の全面を通過する。このため、熱交換器１０の全面を確実に冷却でき、熱交換器１０における熱交換の効率をより向上できる。 (Action / Effect)
In the present embodiment described above, the front duct 120 is arranged in a plurality of stages in the vehicle vertical direction corresponding to the entire surface of the heat exchanger 10 along the vehicle width direction at the front portion of the heat exchanger 10. The ejector nozzle 130 formed in the partial duct 120 blows air sent from the side duct 110 toward the heat exchanger 10. Thereby, the air discharged from the ejector nozzle 130 passes through the heat exchanger 10 while attracting the air in the front part of the front duct 120. That is, the air discharged from the ejector nozzle 130 passes through the entire surface of the heat exchanger 10 together with the air in the front portion of the front duct 120 attracted by the air. For this reason, the entire surface of the heat exchanger 10 can be reliably cooled, and the efficiency of heat exchange in the heat exchanger 10 can be further improved.

加えて、案内板１４０は、エジェクタノズル１３０から吹き出された空気を熱交換器１０へ案内する。つまり、エジェクタノズル１３０から放出された空気は、コアンダ効果により案内板１４０に沿って送風される。これにより、案内板１４０に沿った空気は、熱交換器１０に向かうに連れて除々に前部ダクト１２０から離れるように流れる。従って、熱交換器１０を通過する際の空気の風速分布が均等になりやすく、熱交換器１０の全面をさらに確実に冷却できる。   In addition, the guide plate 140 guides the air blown from the ejector nozzle 130 to the heat exchanger 10. That is, the air discharged from the ejector nozzle 130 is blown along the guide plate 140 due to the Coanda effect. Thereby, the air along the guide plate 140 gradually flows away from the front duct 120 toward the heat exchanger 10. Therefore, the air velocity distribution when passing through the heat exchanger 10 is likely to be uniform, and the entire surface of the heat exchanger 10 can be cooled more reliably.

その上、案内板１４０は、車幅方向に対して所定間隔おきに設けられる。これにより、案内板１４０により前部ダクト１２０の間を支持することができ、前部ダクト１２０の剛性を確保できる。   In addition, the guide plates 140 are provided at predetermined intervals in the vehicle width direction. Thereby, the space between the front ducts 120 can be supported by the guide plate 140, and the rigidity of the front duct 120 can be ensured.

本実施形態では、案内板１４０は、連結基台１２３上に設けられる。これにより、エジェクタノズル１３０から放出された空気が通過しないとされる連結基台１２３上を有効活用して、エジェクタノズル１３０から放出された空気の風量のロスを軽減でき、熱交換器１０を通過する際の空気の風速分布がさらに均等になりやすい。   In the present embodiment, the guide plate 140 is provided on the connection base 123. Thereby, the loss of the air volume of the air discharged from the ejector nozzle 130 can be reduced by effectively utilizing the connection base 123 on which the air discharged from the ejector nozzle 130 is not passed, and the air passes through the heat exchanger 10. The air velocity distribution during the process tends to be even.

本実施形態では、案内板１４０の幅Ｗは、熱交換器１０に向かって細くなるように形成される。これにより、エジェクタノズル１３０から放出された空気は、案内板１４０により車幅方向に仕切られていても、案内板１４０の後部（熱交換器１０寄りの端部）で合流しやすくなる。従って、エジェクタノズル１３０から放出された空気の風量のロスをより軽減でき、熱交換器１０を通過する際の空気の風速分布がさらに均等になりやすい。   In the present embodiment, the width W of the guide plate 140 is formed so as to become narrower toward the heat exchanger 10. Thereby, even if the air discharged from the ejector nozzle 130 is partitioned in the vehicle width direction by the guide plate 140, it becomes easy to merge at the rear portion of the guide plate 140 (end near the heat exchanger 10). Therefore, the loss of the air volume of the air discharged from the ejector nozzle 130 can be further reduced, and the wind speed distribution of the air when passing through the heat exchanger 10 is likely to be more uniform.

本実施形態では、送風機２１及び空気案内器１００は、熱交換器１０が固定されるラジエータコアサポート３０に取り付けられる。これにより、送風機２１及び空気案内器１００を別途固定するための部材が不要である。このため、車両重量の増大を招くことなく、熱交換ユニット１の製造コストの低減にも寄与する。   In the present embodiment, the blower 21 and the air guide 100 are attached to the radiator core support 30 to which the heat exchanger 10 is fixed. Thereby, the member for fixing the air blower 21 and the air guide 100 separately is unnecessary. For this reason, it contributes also to the reduction of the manufacturing cost of the heat exchange unit 1 without causing the increase in a vehicle weight.

本実施形態では、各前部ダクト１２０の湾曲部１２２は、ビスＢを介して本体部１２１の連結基台１２３に連結されている。これにより、本体部１２１と湾曲部１２２との固定強度（保持力）を増大させることでき、エジェクタノズル１３０の周囲の剛性を確保できる。つまり、エジェクタノズル１３０の周囲がばたつくことなく、異音の発生を防止できるとともに、エジェクタノズル１３０放出する空気を安定させることができる。   In the present embodiment, the curved portion 122 of each front duct 120 is connected to the connection base 123 of the main body portion 121 via a screw B. Thereby, the fixing strength (holding force) between the main body 121 and the curved portion 122 can be increased, and the rigidity around the ejector nozzle 130 can be secured. In other words, the noise around the ejector nozzle 130 does not flutter, the generation of abnormal noise can be prevented, and the air discharged from the ejector nozzle 130 can be stabilized.

（変更例）
次に、上述した案内板１４０の変更例について、図面を参照しながら説明する。図７は、変更例に係る案内板１４０近傍を示す斜視図である。なお、上述した実施形態に係る案内板１４０と同一部分には同一の符号を付して、相違する部分を主として説明する。 (Example of change)

In the modified example, the width W along the vehicle width direction of each guide plate 140 is formed so as to become gradually narrower toward the heat exchanger 10, similarly to each guide plate 140 of the above-described embodiment. Yes.

具体的には、図７に示すように、各案内板１４０は、複数段の前部ダクト１２０の間に立設されており、上端及び下端の少なくとも一方が前部ダクト１２０に取り付けられている。各案内板１４０の車両上下方向に沿った高さＨは、熱交換器１０に向かって高くなるように形成されている。なお、案内板１４０の側面視の形状については、図７（ａ）に示すように略三角状であってもよく、図７（ｂ）に示すように略台形状であってもよい。   Specifically, as shown in FIG. 7, each guide plate 140 is erected between a plurality of stages of the front duct 120, and at least one of the upper end and the lower end is attached to the front duct 120. . A height H along the vehicle vertical direction of each guide plate 140 is formed so as to increase toward the heat exchanger 10. In addition, about the shape of the side view of the guide plate 140, a substantially triangular shape may be sufficient as shown to Fig.7 (a), and a substantially trapezoid shape may be sufficient as shown in FIG.7 (b).

このような変更例であっても、上述した実施形態と同様に、熱交換器１０を通過する際の空気の風速分布が均等になりやすく、熱交換器１０の全面を確実に冷却できる。   Even in such a modified example, similarly to the above-described embodiment, the air velocity distribution when passing through the heat exchanger 10 is likely to be uniform, and the entire surface of the heat exchanger 10 can be reliably cooled.

加えて、案内板１４０の高さＨは、熱交換器１０に向かって高くなるように形成される。これにより、案内板１４０の材料費や重量を低減でき、車両重量の増大を招くことなく、熱交換ユニット１の製造コストの低減にも寄与する。   In addition, the height H of the guide plate 140 is formed so as to increase toward the heat exchanger 10. Thereby, the material cost and weight of the guide plate 140 can be reduced, which contributes to the reduction of the manufacturing cost of the heat exchange unit 1 without increasing the vehicle weight.
