Description of the Related Art FIG. 35 is a perspective view (perspective view of the device from the bottom of the vehicle) of a conventional general-purpose power converter for a high-speed railway vehicle, showing an example of the arrangement of the equipment on the vehicle body, and FIG. FIG. 37 is a front view (cross-sectional view taken along the line AA in FIG. 35) of the electric vehicle power conversion device for a railway vehicle, and FIG. It is a top view (BB sectional drawing of FIG. 36).
【０００３】図３６に示すように、一般的な高速鉄道車
両（高速鉄道車両とは、通常、平均走行速度が１８０〜

熱する。As shown in FIG. 36, a general high-speed railway vehicle (a high-speed railway vehicle usually has an average traveling speed of 180 to
It refers to a rail car that travels at 190 km / h or more)
As a cooling structure in the power converter for electric power, the semiconductor element 1 which is a heating element is attached to the heat receiving surface 3 of the cooler 2, and the heat generated from the semiconductor element 1 is transferred to the heat radiating section 5 via the refrigerant 4.
【０００４】放熱部５は、電力変換装置本体６の内部に
設けた風洞７内に設置され、電動送風機８により風洞７
内の放熱部５に冷却風９を送風して、開放部１０に排熱
するように構成されている。The heat radiating section 5 is installed in a wind tunnel 7 provided inside the main body 6 of the power converter, and the wind tunnel 7 is driven by an electric blower 8.
Cooling air 9 is blown to the heat radiating portion 5 inside and the heat is exhausted to the open portion 10.
【０００５】このような一般的な高速鉄道車両用電力変
換装置は、大容量であることから、半導体素子１からの
発熱量が大きく、冷却器２には、高い冷却性能が必要と
されるが、装置全体の小型軽量化に伴ない、冷却器２も
コンパクトな外形および配置とすることが求められてい
る。Since such a general electric power converter for a high-speed railway vehicle has a large capacity, a large amount of heat is generated from the semiconductor element 1 and the cooler 2 is required to have high cooling performance. With the reduction in size and weight of the entire device, the cooler 2 is also required to have a compact outer shape and arrangement.
【０００６】そのため、限られたスペ−ス内において、
冷却器２の放熱部５は、放熱面積を大きく取る必要があ
ることから、放熱部５のフィンピッチが狭く、また風洞
７内においては、図３７に示すように、放熱部５を冷却
風９の送風方向に対して、複数段直列に配置することか
ら、圧力損失が大きくなっている。Therefore, in a limited space,
Since the heat radiating portion 5 of the cooler 2 needs to have a large heat radiating area, the fin pitch of the heat radiating portion 5 is narrow, and in the wind tunnel 7, as shown in FIG. Since a plurality of stages are arranged in series with respect to the blowing direction of, the pressure loss is large.
【０００７】この結果、冷却器２の能を充分に引き出す
ための風量を確保するためには、動送風機８は大型のも
のでなければならず、重量が重く、騒音も大きいものと
なっている。As a result, in order to secure a sufficient air volume to fully bring out the performance of the cooler 2, the dynamic blower 8 must be large in size, heavy in weight, and loud in noise. .
【０００８】さらに、電動送風機８は、回転部の定期的
な点検、および部品交換等のメンテナンスも必要であ
る。Further, the electric blower 8 also requires periodical inspection of the rotating part and maintenance such as parts replacement.
【０００９】また、冷却器２においても、前述したよう

よる目詰まりを起こすために清掃が必要であるが、放熱
部５は風洞７内に設置されており、清掃時には電力変換
装置本体６から冷却器２を取り外さねばならない。Also in the cooler 2, as described above, since the fin pitch of the heat radiating portion 5 is narrow, it is necessary to clean the heat radiating portion 5 to cause clogging due to dust or the like. It is installed inside and the cooler 2 must be removed from the power converter main body 6 at the time of cleaning.

ら、冷却器２には高い冷却性能を必要とせず、放熱部５
を車側１１または底面１２に配置して、自冷または冷却
風９に走行風１３を利用しての電動送風機８を使用しな
い冷却構成が主流となっている。On the other hand, in the conventional line, the cooler 2 does not need high cooling performance because the semiconductor device 1 has a small capacity and a small amount of heat generation as compared with a high-speed vehicle, and the heat radiating portion 5 is not required.
The mainstream is a cooling configuration in which the electric fan 8 is disposed on the vehicle side 11 or the bottom surface 12 and the traveling air 13 is used as the cooling air 9 or the cooling air 9 and the electric blower 8 is not used.
【００１１】高速車両においても、車体１４周囲に走行
風１３は流れており、高速車両故に、その風量も現状の
電動送風機８と相当量であることは確認されている。Even in a high-speed vehicle, the traveling wind 13 is flowing around the vehicle body 14, and it has been confirmed that the air volume of the high-speed vehicle is substantially the same as that of the current electric blower 8.

状となっている。Further, as shown in FIGS. 35 and 36,
In order to obtain high aerodynamic characteristics, recent high-speed vehicles have
The 4 cross section has a rounded shape as a whole, and the appearance of the power converter main body 6 and other equipment 15 under the vehicle floor and between the equipment 16 has a rounded and curved cowl cover 17 on the vehicle side 11. Since the bottom surface has a smooth structure that is substantially flush with the bottom surface 12 of the vehicle body, the entire vehicle body has a uniform cross-sectional shape of the vehicle body 14 without unevenness.

難である。Therefore, the flow around the vehicle body is a flow having a strong directivity along the wall surface of the vehicle body, and in the device arrangement in the current power converter main body 6, the wind tunnel 7 is arranged in a direction substantially perpendicular to the rail 18. As mentioned above, the wind tunnel 7
Since the internal pressure loss is also large, it is difficult to draw in the wind tunnel 7 the traveling wind 13 having the air volume that can sufficiently bring out the performance of the cooler 2.

ある。As described above, in the conventional power conversion device for a high-speed railway vehicle, since the cooling structure uses the large electric blower 8, the weight of the entire device becomes heavy and the noise is also generated. There is a problem that it becomes large.
【００１５】また、走行風を有効に利用した冷却構成と
するためには、現状の装置機器配置では、充分な走行風
を得ることができないという問題点もある。Further, in order to have a cooling structure in which traveling wind is effectively used, there is a problem that sufficient traveling wind cannot be obtained with the current arrangement of devices and equipment.

テナンス性向上に対して大きな弊害でもある。Further, the periodical maintenance of the electric blower 8 and the detaching work at the time of cleaning the cooler 2 are also great obstacles to the improvement of maintenance efficiency.
