Definitions

  • the present invention relates to a moving vehicle and particularly relates to a railway vehicle including an engine generator and a main motor.
  • a railway vehicle running directly through an electrified route and a non-electrified route includes a device for supplying electric power obtained from an overhead line or a third rail to a main motor and a device for supplying electric power obtained by operating a generator with the use of an engine to the above main motor.
  • a railway vehicle is referred to as "DEMU (Diesel Electric Multiple Unit)", “Bi-mode”, “EDC system”, or the like.
  • DEMU Diesel Electric Multiple Unit
  • engine generator A device for operating the generator with the use of the engine
  • the DEMU is roughly classified into two kinds of systems.
  • One system is a centralized power generation system composed of a power-generation vehicle on which an engine generator for generating electric power for the whole composition is mounted and an passenger car on which no engine generator is mounted.
  • the other system is a distributed power generation system that does not include a power-generation vehicle and is composed of a plurality of passenger cars on which comparatively small engine generators are distributively mounted and a passenger car on which no engine generator is mounted.
  • the engine generator can be intensively mounted on the power-generation vehicle, and therefore, for example, the engine generator can be easily increased in size (increased in output), and the engine generator that tends to be a large vibration source and sound source can be provided away from the passenger car.
  • an axle weight (weight) of the power-generation vehicle tends to be excessively large.
  • the distributed power generation system electric power necessary for vehicles of the composition to run is obtained by the engine generators which are distributively arranged, and therefore it is only necessary to prepare a plurality of engine generators each of which has small output. Further, it is possible to improve a degree of freedom of a recombination of the vehicle composition. Furthermore, the distributed power generation system has redundancy in which, even if a single engine generator is broken, operation can be continued by using engine generators mounted on other vehicles. Therefore, these days, the distributed power generation system is employed in most of the DEMUs.
  • main circuit electrical wires for supplying electric power generated in the engine generator to a device such as a main converter installed under the floor of the passenger car need to be laid in a limited small space under the floor of the passenger car. Therefore, the main circuit electrical wires are laid in the vicinity of the engine generator serving as a heat source in many cases.
  • the main circuit electrical wires are exposed to a high-temperature environment due to not only heat generated by the main circuit electrical wires themselves but also heat from the engine generator, and a service life thereof may be reduced due to, for example, reduction in insulation performance thereof.
  • PTL 1 discloses a vehicle including main circuit electrical wires for transmitting electrical energy in a duct in order to prevent the electrical wires themselves from overheating, in which the main circuit electrical wires are cooled with air by supplying cooling air to this duct while the vehicle is being operated.
  • JP 2011-240747 A proposes a railway vehicle with an underfloor power converter and a convection generation mechanism.
  • a noise level in the passenger car is reduced by surrounding the engine generator mounted under the floor of the passenger car with, for example, a side cover having a sound insulation property to prevent a noise emitted from the engine generator from being propagated to the inside of the passenger space.
  • the side cover provided around the engine generator blocks a flow of cooling air around the engine generator and a wiring gutter receiving the wires. Therefore, heat tends to be stayed around the engine generator and the wiring gutter, which causes further overheating of the electrical wires.
  • the electrical wires are laid in the vicinity of the engine generator mounted under the floor as described above, the electrical wires are susceptible to a thermal influence of the engine generator, and, in addition, the electrical wires themselves are increased by Joule heat due to increase in current caused by increase in output of the engine generator in some cases.
  • the electrical wires having a high temperature are quickly deteriorated over time in terms of an insulation performance and the like. Therefore, the insulation performance may be decreased to reduce a service life. Reduction in service life causes increase in maintenance costs because maintenance work such as replacement needs to be performed at a short cycle.
  • an object of the invention is to provide a moving vehicle having a long service life by reducing a thermal influence from an engine generator on electrical wires provided under a floor in a DEMU of the distributed power generation system to prevent the electrical wires from being exposed to a high temperature.
  • a moving vehicle of the invention includes: an engine generator provided under a vehicle body; coolers, each of which includes a radiator connected to the engine generator and an air blower; and electrical wiring gutters arranged under the vehicle body along a vehicle-body longitudinal direction, the electrical wiring gutters receiving electrical wires, wherein: the coolers are arranged at both end portions in a vehicle-body width direction under the vehicle body so as to face to each other and form airflows directed from the both end portions in the vehicle-body width direction toward the center of the vehicle body by using the respective air blowers; and the airflows that have collided at the center of the vehicle body change directions to be directed toward the electrical wiring gutters.
  • the moving vehicle having a long service life, the moving vehicle being capable of running directly through an electrified route and a non-electrified route and preventing increase in temperature of electrical wires provided in electrical wiring gutters by directing airflows formed by air blowers of coolers to the electrical wiring gutters.

  • the underframe and the structure bodies are basically made of a panel material connected to a hollow extruded shape material (double skin) made of aluminum alloy, the hollow extruded shape material being formed by connecting two facing faceplates via ribs.
  • a bogie 16 including a plurality of wheelsets supported to be rollable on a track is provided under each of the both end portions in the longitudinal direction 520.
  • a main motor (not shown) is mounted on the bogie 16, and the railway vehicle 1 runs by supplying electric power to this main motor to drive the wheelsets.
  • a power collection device for collecting electric power from an overhead line is provided on a roof of the railway vehicle 1 of a DEMU system, and a power collection shoe for collecting electric power from a third track provided along the track is provided on a side surface of the bogie 16.
  • the railway vehicle 1 runs by collecting electric power by using the power collection device or the power collection shoe and then supplying the collected electric power to a main transformer and a main converter to drive the main motor.
  • the railway vehicle 1 runs by supplying electric power obtained by driving a generator with the use of an engine mounted on the railway vehicle 1 to the main converter to drive the main motor.
  • the railway vehicle 1 includes both the power collection device or power collection shoe and the engine generator and can therefore mutually run directly through the electrified route and the non-electrified route.
  • Fig. 2 is an enlarged view of an engine-generator mounting part (A portion in Fig. 1 ) under a floor of the railway vehicle 1 according to this example.
  • Fig. 3 is a top view (B-B cross-sectional view in Fig. 2 ) of the engine-generator mounting part under the floor of the railway vehicle 1 according to this example.
  • the engine generator mounted under the floor of the railway vehicle 1 mainly includes an engine 24 and a generator 25 connected to the engine 24.
  • the engine 24 is connected to a cooler including a radiator 26 for cooling cooling water having a temperature increased by circulating the cooling water on the inside thereof to cool various portions with water and a fan 30 for sending ambient air to the radiator 26 and is also connected to exhaust gas processing devices 34 for removing hazardous material from exhaust gas discharged from the engine 24.
  • Those devices are integrally supported together with the engine 24 by using a frame or the like.
  • the engine 24 is a diesel engine using light fuel oil as a fuel
  • the exhaust gas processing devices 34 are for removing nitrogen oxides and particulate matter (PM) in exhaust gas.
  • two coolers each of which includes the radiator 26 and the fan 30, are provided, and, also as shown in Fig. 3 , the radiators 26 of the respective coolers are arranged along the longitudinal direction 520 on the both sides in the width direction 510 under the railway vehicle 1 and are also arranged so that the fans 30 of both the coolers are adjacent to each other along the longitudinal direction 520 of the engine 24 so as to face to each other.
  • Fig. 4 is a cross-sectional view (C-C cross-sectional view in Fig. 2 ) of the railway vehicle, which shows an engine mounting position in the engine generator according to this example.
  • Side covers 14 are provided on both sides of the engine 24 in the width direction 510 so that a noise emitted from the engine generator is not propagated to the periphery of the railway vehicle 1.
  • each of the side covers 14 arranged along the radiators 26 on both sides thereof has a lattice 22 that does not interrupt sending of air from the fan 30 and prevents damage caused by a flying object or the like.
  • an electrical wiring gutter 44 receiving control electrical wires 40 related to control of commands or the like to various devices is provided, and, at the other end portion thereof, an electrical wiring gutter 44 receiving main circuit electrical wires 42 through which a current or the like supplied to the main motor and the like flows is provided.
  • each engine 24 has axis output of about 500 to 700 kW.
  • the radiators 26 provided along with the engine generator have a capability of removing an amount of heat of about 300 kW in total for a single engine.
  • a temperature of a space surrounded by the underframe 12 and the side covers 44 tends to be increased at the time of an overload due to heat 540 or the like radiated from the engine 24 and the exhaust gas processing devices 34. Therefore, the electrical wiring gutters 44 provided in this space and the control electrical wires 40 and the main circuit electrical wires 42 received therein are also exposed to a high temperature.
  • Fig. 5 is a cross-sectional view (D-D cross-sectional view in Fig. 2 ) of the railway vehicle, which shows a radiator mounting part of the engine generator according to this example.
  • the fan 30 sucks air around the railway vehicle 1 (hereinafter, referred to as "ambient air") through the lattice 22 provided in the side cover 14, thereby cooling the radiator 26 with ambient air.
  • the coolers including the radiators 26 and the fans 30 are arranged on the both end portions in the width direction 510 under the railway vehicle 1 so that the radiators 26 are directed outward (in a direction away from the center in the width direction 510), the fans 30 are directed inward (in a direction toward the center in the width direction 510), and the fans 30 on both sides face to each other, thereby attracting ambient air inward from the outside.
  • a temperature of a flow (first airflow) 500 of ambient air linearly passing through the radiator 26 toward the center in the width direction 510 is increased by removing heat from the radiator 26.
  • the ambient air having an increased temperature collides at the center in the width direction 510, and therefore a direction thereof is changed upward and downward.
  • a flow (second airflow) 501 whose direction has been changed upward collides with a heat shielding material 32 provided on the lower surface of the underframe 12 and becomes a flow (second airflow) directed from the center in the width direction 510 toward both sides thereof (direction of side cover 14), and the flow is discharged to the outside of the vehicle through a gap between the underframe 12 and a top end portion of the side cover 14.
  • the second airflow 501 flows at a position higher than that of the first airflow 500 (position closer to the lower surface of the underframe 12).
  • the second airflow 501 collides with the shielding material 32 to cool the shielding material, changes a direction thereof, and flows through the gap between the lower surface of the underframe 12 and the top end portion of the side cover 14. During this process, the second airflow 501 cools the electrical wiring gutter 44.
  • a flow (third airflow) 502 which has collided at the center in the width direction 510 and has changed a direction downward, becomes a flow directed toward a track 90 and flows between a portion below the radiator 26 and the track 90 in a direction away from the railway vehicle 1.
  • the flow 501 of the air that has passed the radiator 26 has a temperature of about 80 to 90°C at the time of high-load operation in which the railway vehicle 1 departs from a station and accelerates. This temperature is satisfactorily lower than a temperature of the lower surface of the underframe 12 (heat shielding material 32) exposed to heat radiated from the engine 24 and a temperature of a region surrounded by the lower surface of the underframe 12 and the side covers 14.
  • the electrical wiring gutter 44 can be effectively cooled by the flow 501 of the air that has passed the radiator 26, and the main circuit electrical wires 42 included therein can be securely prevented from having a high temperature at which insulation deterioration occurs.

  • the railway vehicle 1 includes electrical devices such as the main motor, the main converter, and the generator and also includes electrical wire groups such as the control electrical wires 40 and the main circuit electrical wires 42 for transmitting electrical energy and signals between those electrical devices.

  • the electrical wiring gutter 44 is attached to the lower surface of the underframe 12.
  • the temperature of the region surrounded by the underframe 12 and the side covers 14 shown in Fig. 3 and Fig. 4 is increased due to an influence of the heat 540 from a surface of the engine 24, the exhaust gas processing devices 34, and the like, and therefore a temperature around the electrical wiring gutters 44 is increased to about 100°C in some cases.
  • heat transfer from the engine 24 is caused by convective heat transfer or is caused by radiative heat transfer.
  • the convective heat transfer is such that air having a temperature increased by heat transferred from the engine 24 to air therearound flows to the vicinity of the electrical wires through the electrical wiring gutters 44.
  • the radiative heat transfer is such that heat is transferred to surfaces of the electrical wiring gutters 44 via electromagnetic waves emitted from the surface of the engine 24.
  • the periphery of the electrical wiring gutters 44 becomes a high-temperature atmosphere due to an influence of heat from the engine 24, and, in addition, the main circuit electrical wires 42 have a high temperature also due to Joule heat of the main circuit electrical wires 42 themselves. Therefore, those electrical wire groups have a specification to withstand a high temperature.
  • the main circuit electrical wires 42 may have a high temperature due to generation of heat caused by Joule heat in addition to increase in ambient temperature.
  • the electrical wiring gutters 44 provided in the vicinity of the engine 24 and the exhaust gas processing devices 34 have a sandwiched (laminated) structure having a heat insulation property with which increase in the temperature of the electrical wiring gutters 44 caused by an influence of heat from the engine 24 and the like hardly occurs.
  • the electrical wiring gutters 44 are formed by inserting a heat insulation material 46 between two plates 48a and 48b made of aluminum alloy, have a substantially U-shaped cross-sectional shape in a direction across the longitudinal direction 520, and hold the control electrical wires 40 and the main circuit electrical wires 42 in recessed portions formed in upper surfaces thereof.

  • the electrical wiring gutter 44 is provided in the vicinity of the radiator 26 and is arranged at a position exposed to the flow 501 of the air (second airflow) induced by the fan 30 as described above.
  • the electrical wiring gutter 44 having the substantially U-shaped cross-sectional shape in a direction across the longitudinal direction 520 does not include the heat insulation material 46 or the plate 48b shown in Fig. 6 and only includes the plate 48a, and a plurality of radiating fins 50 are provided to be laminated at predetermined intervals under the plate 48a along the longitudinal direction 520 of the railway vehicle 1.
  • the radiating fins 50 are made of material having a high thermal conductivity such as aluminum alloy, and each of the radiating fins includes a base 50b connected to the plate 48a forming the electrical wiring gutter 44 and an extension part 50a extending downward from one end portion of the base 50b.

  • the extension parts 50a are exposed to ambient air having a temperature lower than that of the flow 501 of the air having a temperature increased by passing the air through the radiator 26. Therefore, heat, which has been moved by heat transfer from the electrical wiring gutter 44 (plate 48a) to the bases 50b, is moved by thermal conduction through the inside of the radiating fins 50 to the extension parts 50a having a lower temperature. The heat transmitted to the extension parts 50a by thermal conduction is brought into contact with ambient air (flow 500 of air) having a low temperature and is then cooled.

Thereafter, heat, which has been moved by thermal conduction to the part corresponding to L2, is effectively removed by the flows 500 to 502 of the air generated by the fan 30 of the radiator 26 toward ambient air, and the electrical wiring gutter 44 is effectively cooled over the whole length (sum of L1 and L2) thereof. Therefore, the electrical wiring gutter 44 and the main circuit electrical wires 42 are maintained at a low temperature.
  • the electrical wiring gutter 44 and the main circuit electrical wires 42 can be maintained at a low temperature also by providing, instead of the radiating fins 50, a heat pipe (not shown) directly connected to the electrical wiring gutter 44 to effectively remove heat from the electrical wiring gutter 44 toward a flow of air.
