【発明の実施の形態】本発明の実施例の詳細を述べる前に、その概要を述べる。 DETAILED DESCRIPTION OF THE INVENTION Before describing the details of the embodiments of the invention a brief overview.

【0009】気密構造である高速車両等の換気では、外気と車内側給気ファンとの間に吸込管を、また車内側の排気ファンと外気との間に吐出管を用いて連続的に換気をしている。 [0009] In ventilation fast vehicles such as a gas-tight structure, the suction pipe between the outdoor air and the interior side air supply fan, also continuously ventilated with discharge pipe between the exhaust fan and the outside air of the interior side It has a.

【0010】本発明の実施例では、換気装置用ファンとしてターボ形ファン(後向羽根車付ファン)を使用し、ファンとして高効率化を図ると同時に、インバ−タ等により駆動モータを高速化し、駆動モ−タの両軸に給気ファンと排気ファンを取り付け、さらに駆動モータ、 [0010] In embodiments of the present invention uses a turbo-type fan (fan with backward curved impeller) as a fan ventilator, at the same time achieve high efficiency as a fan, inverter - to speed up the drive motor by motor or the like , the drive motor - mounting the air supply fan and the exhaust fan to both axes of the motor and further drive motor,
両ファン、および消音器を外筒ケーシングに内蔵する。 Both fans, and the muffler is incorporated in the outer cylinder casing.
これにより従来より大幅な小形化と低騒音化を図っている。 Thereby working to conventionally significant miniaturization and low noise. また、ターボ形ファンの羽根車出口は静圧が高く、羽根車の吐出空気を直接モータ外周に導流することができるので、給気と排気をモータ外周に導流して、しかも給気と排気が混合せずモータ軸に平行に通風させる。 Further, the impeller outlet of the turbo type fan has a high static pressure, it is possible to diversion to direct motor periphery a discharge air of the impeller by flowing electric exhaust and air supply to the motor periphery, moreover the air supply exhaust is parallel to the air across the motor shaft without mixing. これにより従来のモータ冷却ダクトを不用とし給気路と排気路の容積を大幅に縮小すると同時に、給気路と排気路が外筒ケーシング内に内蔵しているので、従来の給気路と排気路からのファン騒音が大幅に低減して、大幅な低騒音化が図れる。 At the same time thereby greatly reducing the conventional motor cooling duct and unnecessary and to air supply passage volume of the exhaust path, the supply passageway and exhaust channel are incorporated in the outer cylinder casing, and exhaust conventional air supply path fan noise from the road is greatly reduced, thereby the significant reduction in noise.

【0011】さらにモータ外周にフィンを付けて通気でモータの冷却を加速すると同時に、給気と排気が混合せずに隣接して通風できるようにフィンが仕切板として機能している。 [0011] At the same time further accelerate the cooling of the motor ventilation with a fin to the motor periphery, the fins to allow air adjacent without mixing exhaust and air supply are functions as a partition plate.

【0012】本発明の換気装置ではモータの冷却用空気として、外気(給気)でも車内気(排気)でも何れか一方を使用することができる。 [0012] As the cooling air of the motor ventilation apparatus of the present invention, it is possible to use either one even-vehicle air (exhaust) even outside air (supply air). 一方の空気が低温で他方が高温の場合は、低温の空気をモータ外周のフィン間に通気してモータを高効率でモータを冷却し、他方の高温空気は低温空気とモータ外周フィンのさらの外周を通気させて低温側の空気及びモータフィンと断熱させ、この断熱材により通気路からのファン騒音をさらに低減することができる。 If one of the air and the other at a low temperature is hot, cold air was bubbled between the fins of the motor outer peripheral motor to cool the motor with high efficiency, the other hot air cold air and motor periphery fins further the outer periphery was vented to air and the motor fins and the heat insulating of the low temperature side, it is possible to further reduce the fan noise from the ventilation passage by the heat insulating material.

【0013】また本発明では外気(給気)と排気が熱交換しながらモータを冷却することもできる。 [0013] The present invention can also be exhausted and outdoor air (supply air) to cool the motor while the heat exchanger. この場合のフィンは外気と排気の仕切板としての機能とモータ冷却の機能を兼ねており構造が簡単であるから、換気装置さらに小型化が図れる。 Since the fin of the case also serves the functions and capabilities of the motor cooling as a partition plate of the exhaust and outdoor air structure is simple, the ventilator further can be miniaturized.

【0014】さらに本発明では駆動モ−タに直結している給気ファンと排気ファンとは別のファンにより低温空気をモータの外周に導流してモータを冷却することもできる。 [0014] The present invention further drive motor - it is also possible to cool the motor by flowing guide cold air to the outer periphery of the motor by a separate fan from the air supply fan connected directly to the motor and the exhaust fan.

【0015】以上述べたように、本発明の実施例によれば、静音化の図られた高効率で小型の換気装置が提供できる。 [0015] As described above, according to an embodiment of the present invention can provide a compact ventilator with high efficiency was achieved with noise reduction.

【0023】これにより、駆動モータ2が給気と排気によって冷却されて、また給気と排気が同時に熱交換が出来る。 [0023] Thus, the drive motor 2 is cooled by the exhaust and supply air, also air supply and exhaust can heat exchange simultaneously. 図4、図5は、とくに排気が給気より低温の場合であり、この場合駆動モータ2が排気によって効率よく冷却されると同時に、給気も低温となり、給気フアン下流の空調機の空調負荷も軽減されて空調機の高性能化が得られる(空調能力が約15%増加する)。 4, FIG. 5 is particularly when the exhaust is low than the air supply, at the same time in this case the drive motor 2 can be efficiently cooled by the exhaust, supply air also becomes low, the air conditioning of the air supply fan downstream of the air conditioner load high performance be mitigated air conditioner is obtained (the air-conditioning capacity is increased about 15%).
