これにより、筐体３ａ内を通過する冷却風と各バッテリモジュール３ｆを熱交換させて各バッテリモジュール３ｆを冷却できるようになっている。 Also, in the housing 3a, there is an upper passage 3g in which cooling air introduced from the introduction port 3c through the intake duct 4, the blower fan 2, and the connection duct 5 flows along the outer peripheral surface of the battery module 3f. A bypass passage 3h through which the cooling air in the upper passage passes through a gap between adjacent battery modules 3f, and a lower passage 3i in which the cooling air after passing through the bypass passage 3h goes to the discharge port 3e are formed.
Thereby, each battery module 3f can be cooled by exchanging heat between the cooling air passing through the housing 3a and each battery module 3f.

以下、吸気ダクト４について詳述する。
図１に示すように、吸気ダクト４は樹脂製で管状に形成される他、その一端側開口部７がブロアファン２に連通接続される一方、他端側開口部８が車室内６に連通されている。

また、吸気ダクト４の他端側開口部８の内側にはキャップ１０が嵌合した状態で装着されると共に、このキャップ１０には複数の連通孔１０ａが貫通形成されており、これによって、車室内６と吸気ダクト４の他端側開口部８とが連通状態となっている。
なお、連通穴１０ａの形状、形成数、及び開口面積等は適宜設定できる。 Hereinafter, the intake duct 4 will be described in detail.
As shown in FIG. 1, the intake duct 4 is made of resin and formed in a tubular shape, and its one end side opening 7 is connected to the blower fan 2, while the other end side opening 8 is connected to the vehicle interior 6. Has been.
Specifically, as shown in FIG. 2, an opening 16a is formed in the rear pershell 9 provided behind the rear seat in the vehicle interior, and the other end side opening 8 of the intake duct 4 faces this. Has been placed.
In addition, a cap 10 is fitted in the inside of the other end side opening 8 of the intake duct 4 and a plurality of communication holes 10a are formed in the cap 10 so as to pass therethrough. The room 6 and the opening 8 on the other end side of the intake duct 4 are in communication.
In addition, the shape of the communication hole 10a, the number of formation, an opening area, etc. can be set suitably.

吸気ダクト４の全体形状は、前述した他端側開口部８から縮径した縮径部１１ａを有して下方へ延設された垂直部１１から略Ｕ字状に屈曲した後、さらに、水平な水平部１２を介してブロアファン２の上部に連通接続された形状となっている。   The entire shape of the intake duct 4 is formed by bending a substantially U-shaped portion from a vertical portion 11 having a reduced diameter portion 11a that is reduced in diameter from the opening 8 on the other end side and extending downward. The shape is connected to the upper part of the blower fan 2 through the horizontal part 12.

そして、吸気ダクト４の前述した略Ｕ字状の下部付近は、下方に凸となるように形成され、これにより、吸気ダクト４の途中に空間１３を有するトラップ部１４（請求項のトラップ手段に相当）が形成されている。
また、空間１３内のトラップ部１４の底部１４ｅから所定高さ位置には、導風リブ１５（請求項の導風手段に相当）が該トラップ部１４と一体的に設けられている。
導風リブ１５は、水平部１２側へ行くにつれて高くなるように傾斜した上面１５ａを有する平板状に形成されている。
さらに、導風リブ１５の上端部は、水平部１２の下端よりも低い位置に配置されている。 The vicinity of the above-described substantially U-shaped lower portion of the intake duct 4 is formed so as to protrude downward, whereby a trap portion 14 having a space 13 in the middle of the intake duct 4 (in the trap means of the claims) Equivalent) is formed.
Further, air guide ribs 15 (corresponding to the air guide means in the claims) are provided integrally with the trap portion 14 at a predetermined height position from the bottom portion 14 e of the trap portion 14 in the space 13.
The air guide rib 15 is formed in a flat plate shape having an upper surface 15a that is inclined so as to become higher toward the horizontal portion 12 side.
Furthermore, the upper end portion of the air guide rib 15 is disposed at a position lower than the lower end of the horizontal portion 12.

トラップ部１４の底部１４ｅ中央には、下方へ突出した排出パイプ１６が空間１３と連通した状態で接続されている。
なお、図示を省略するが、排出パイプ１６の下端開口部には、車外に連通したホース（図示せず）が接続される。

次に、作用を説明する。
以下、図２を用いてバッテリ冷却装置１の作用を説明する。 Next, the operation will be described.
Hereinafter, the operation of the battery cooling device 1 will be described with reference to FIG.

［バッテリ冷却時における車室内空気の導入について］
このように構成されたバッテリ冷却装置１では、バッテリ冷却時において、即ち、ブロアファン２が作動し、車室内空気（図２中破線矢印で図示）を吸気ダクト４の他端側開口部８から吸入した後、垂直部１１、トラップ部１４、水平部１２を介してブロアファン２に導く。
この際、導風リブ１５の上面１５ａが水平部１２側に行くにつれて高くなるように設けられているため、トラップ部１４に流入した車室内空気の略全量を導風リブ１５の上面１５ａに沿って水平部１２へ導くことができる。
また、車室内空気の一部は、導風リブ１５の下方を通過して水平部１２へ向かうが、この際、トラップ部１４の対向する両側壁14a,14bの下部には大きな曲部14c,14dが形成されているため、車室内空気をスムーズに水平部１２へ導くことができる。 [Introduction of vehicle interior air during battery cooling]
In the battery cooling device 1 configured as described above, when the battery is cooled, that is, the blower fan 2 is operated, and air in the passenger compartment (shown by a broken line arrow in FIG. 2) is sent from the opening 8 on the other end side of the intake duct 4. After inhalation, the air is guided to the blower fan 2 through the vertical part 11, the trap part 14, and the horizontal part 12.
At this time, since the upper surface 15 a of the air guide rib 15 is provided so as to increase toward the horizontal portion 12, substantially the entire amount of vehicle interior air that has flowed into the trap portion 14 flows along the upper surface 15 a of the air guide rib 15. To the horizontal portion 12.
A part of the passenger compartment air passes below the air guide ribs 15 and goes to the horizontal part 12. At this time, large curved parts 14c, 14b, Since 14d is formed, the vehicle interior air can be smoothly guided to the horizontal portion 12.

［バッテリ冷却時における液体の侵入について］
ここで、従来の発明にあっては、車室内空気と共に液体（例えば飲料物、車室内清掃用洗剤等）が筐体内に侵入した場合には、液体がバッテリに飛散して電気絶縁不良、腐食、詰まり等の不具合が生じて、バッテリの性能が低下する虞があった。
これに対し、実施例１では、車室内空気と共にトラップ部１４に流入した液体（図２中一点鎖線矢印で図示）は、トラップ部１４の底部に移動して排出パイプ１６から排出される一方、車室内空気は導風リブ１５の上面１５ａに沿って水平部１２へ誘導されるため、車室内空気と液体を完全に分離でき、液体が水平部１２側（バッテリ３ｂ側）に向かうのを防止できる。
また、液体の一部Ｘ１は、垂直部１１の縮径部１１ａ及び壁面を伝って導風リブ１５の上面１５ａに落下した後、該上面１５ａを伝ってトラップ部１４の底部１４ｅに至り、液体の一部Ｘ２は、垂直部１１の縮径部１１ａ及び壁面、トラップ部１４の曲部を伝ってトラップ部１４の底部１４ｅに至るため、液体がトラップ部１４の底部１４ｅに勢い良く落下して飛散するのを低減できる。 [Intrusion of liquid during battery cooling]
Here, in the conventional invention, when a liquid (for example, a beverage, a cleaning agent for cleaning a vehicle interior, etc.) enters the casing together with the air in the vehicle interior, the liquid scatters to the battery, resulting in poor electrical insulation and corrosion. There is a possibility that the battery performance may be deteriorated due to problems such as clogging.
In contrast, in the first embodiment, the liquid (shown by a one-dot chain line arrow in FIG. 2) that flows into the trap portion 14 together with the air in the passenger compartment moves to the bottom of the trap portion 14 and is discharged from the discharge pipe 16. Since the vehicle interior air is guided to the horizontal portion 12 along the upper surface 15a of the air guide rib 15, the vehicle interior air and the liquid can be completely separated, and the liquid is prevented from moving toward the horizontal portion 12 side (battery 3b side). it can.
Further, a part of the liquid X1 travels along the reduced diameter portion 11a and the wall surface of the vertical portion 11 and falls to the upper surface 15a of the air guide rib 15, and then travels along the upper surface 15a to the bottom 14e of the trap portion 14 to reach the liquid. Since part X2 reaches the bottom part 14e of the trap part 14 through the diameter-reduced part 11a and the wall surface of the vertical part 11 and the curved part of the trap part 14, the liquid drops vigorously on the bottom part 14e of the trap part 14. Spattering can be reduced.

また、トラップ部１４に大量の流入した液体が流入した場合において、液体がトラップ部１４の底部１４ｅに一時的に溜まると、この液体（図２中二点鎖線で図示）が車室内空気で吹き上げられて水平部１２へ侵入する虞がある。
これに対し、実施例１では、車室内空気を導風リブ１５の上面１５ａに沿って水平部１２へ導くことができるため、トラップ部１４の底部１４ｅに溜まった液体が車室内空気で吹き上げられるのを防止でき、車室内空気と液体を良好に分離できる。
また、液体の液面が車室空気や車両振動等の影響により大きく波打った際に、この波を導風リブ１５に衝突させて緩衝でき、好適となる。
さらに、導風リブ１５の上端部は水平部１２の下端よりも低い位置に配置されているため、トラップ部１４を通過する車室内風の負圧、あるいはトラップ１４の壁面を毛細管現象によって液体が導風リブ１５の上端部に達した場合であっても、液体が水平部１２側へ飛散して侵入する虞がない。 In addition, when a large amount of inflowing liquid flows into the trap part 14, if the liquid temporarily accumulates at the bottom part 14e of the trap part 14, this liquid (shown by a two-dot chain line in FIG. 2) is blown up by the air in the passenger compartment. And may enter the horizontal portion 12.
On the other hand, in the first embodiment, since the vehicle interior air can be guided to the horizontal portion 12 along the upper surface 15a of the air guide rib 15, the liquid accumulated in the bottom portion 14e of the trap portion 14 is blown up by the vehicle interior air. The vehicle interior air and liquid can be well separated.
Further, when the liquid level of the liquid undulates greatly due to the influence of the passenger compartment air, vehicle vibration, or the like, this wave can collide with the air guide ribs 15 to be buffered, which is preferable.
Further, since the upper end portion of the air guide rib 15 is disposed at a position lower than the lower end of the horizontal portion 12, the liquid is caused by the negative pressure of the vehicle interior wind passing through the trap portion 14 or the wall surface of the trap 14 by capillary action. Even when the upper end of the air guide rib 15 is reached, there is no possibility that the liquid will scatter and enter the horizontal portion 12 side.

［バッテリ非冷却時における液体の侵入について］
一方、バッテリ非冷却時、即ち、ブロアファン２が停止していて、吸気ダクト４内に車室内空気の流れがない場合に、液体が吸気ダクト４内に侵入した際にも前述した場合と同様にトラップ部１４で液体を受け取った後、排出パイプ１６を介して車外へ排出できる。 [Intrusion of liquid when battery is not cooled]
On the other hand, when the battery is not cooled, that is, when the blower fan 2 is stopped and there is no air flow in the vehicle interior in the intake duct 4, the liquid enters the intake duct 4 as in the case described above. After the liquid is received by the trap portion 14, it can be discharged out of the vehicle via the discharge pipe 16.

次に、効果を説明する。
以上、説明したように、実施例１では、吸気ダクト４に下方へ凸となるように形成され、車室内６から吸気ダクト４に侵入した液体が流入するトラップ部１４が設けられるため、ブロアファン２の作動・停止に関わらずトラップ部１４に液体を流入させることができ、液体が吸気ダクト４を介してバッテリ３ｂに飛散するのを防止できる。 Next, the effect will be described.
As described above, in the first embodiment, the blower fan is provided with the trap portion 14 that is formed so as to protrude downward in the intake duct 4 and into which the liquid that has entered the intake duct 4 flows from the vehicle interior 6. Regardless of the operation / stop of 2, the liquid can flow into the trap portion 14, and the liquid can be prevented from scattering to the battery 3 b through the intake duct 4.

また、トラップ部１４の底部１４ｅへ向かう車室内空気をバッテリ３ｂ側へ導く導風リブ１５が設けられるため、大量の液体がトラップ部１４に流入して溜まった場合に、この液体がトラップ部１４の底部１４ｅへ向かう車室内空気により吹き上げられてバッテリ３ｂ側へ侵入するのを防止できる。   In addition, since the air guide ribs 15 are provided to guide the passenger compartment air toward the bottom 14e of the trap part 14 toward the battery 3b, when a large amount of liquid flows into the trap part 14 and accumulates, the liquid is trapped. Can be prevented from being blown up by vehicle interior air toward the bottom 14e of the vehicle and entering the battery 3b.

以下、実施例２を説明する。
実施例２において、上記実施例と同様の構成部材については同じ符号を付してその説明は省略し、相違点のみ詳述する。
図３は実施例２のバッテリ冷却装置を説明する全体図である。 Example 2 will be described below.
In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, the description thereof is omitted, and only differences are described in detail.
FIG. 3 is an overall view for explaining the battery cooling device according to the second embodiment.

図３に示すように、実施例２では、実施例１で説明した垂直部１１を途中から斜め下方へ屈折させて、ここにトラップ部１４側に行くにつれて低くなるように傾斜した傾斜状の傾斜部２０を形成したという点が実施例１と異なる。
従って、実施例１の作用・効果を得ることができることに加えて、吸気ダクト４に侵入した液体を自重により傾斜部２０に伝わせてトラップ部１４にスムーズに流入させることができ、液体がトラップ部１４に直接落下して飛散するのを防止できる。 As shown in FIG. 3, in the second embodiment, the vertical portion 11 described in the first embodiment is refracted obliquely downward from the middle, and is inclined so as to become lower toward the trap portion 14 side. The point which formed the part 20 differs from Example 1. FIG.
Therefore, in addition to obtaining the functions and effects of the first embodiment, the liquid that has entered the intake duct 4 can be transferred to the inclined portion 20 by its own weight and smoothly flowed into the trap portion 14, and the liquid can be trapped. It can prevent falling directly on the part 14 and scattering.

以上、実施例を説明してきたが、本発明は上述の実施例に限られるものではなく、本発明の要旨を逸脱しない範囲の設計変更等があっても、本発明に含まれる。
例えば、バッテリパック３内の構成については適宜設定できる。
また、実施例１では、発熱体を車両用バッテリに適用した例を説明したが、走行用モータのインバータ回路やその他の電気機器に適用しても良く、この際、筐体３ａを省略して接続手段から直接冷却風を吹き付けるようにしても良い。 Although the embodiments have been described above, the present invention is not limited to the above-described embodiments, and design changes and the like within the scope not departing from the gist of the present invention are included in the present invention.
For example, the configuration in the battery pack 3 can be set as appropriate.
In the first embodiment, an example in which the heating element is applied to a vehicle battery has been described. However, the heating element may be applied to an inverter circuit of a traveling motor and other electric devices. In this case, the casing 3a is omitted. Cooling air may be blown directly from the connecting means.
