Definitions

  • the present invention relates to a forced draft cooling system for a diesel-electric locomotive and more particularly to a cooling system for a dynamic brake resistor of a diesel-electric locomotive.
  • a radiator apparatus for the cooling water for a diesel engine which comprises a radiator core, radiator fan and so forth and a dynamic brake apparatus having a resistor are generally disposed at different positions spaced in the longitudinal direction of the locomotive body. Therefore, the body length must be unfavorably long.
  • the above arrangement permits both the radiator core and the resistor to be cooled by a single radiator fan as well as eliminates the need for enlarging the body length.
  • radiator core fins vibrate in portions of the radiator where the wind velocities are particularly high, unfavorably producing vibration noises.
  • resistor since the resistor is installed within a limited space at the inner side of the radiator, it is extremely difficult to demount and remount the resistor in maintenance and inspection.
  • a primary object of the invention to provide a forced draft cooling system for a diesel-electric locomotive in which a dynamic brake resistor is disposed at the inner side of a radiator, capable of preventing the production of vibration noises of radiator core fins as well as easily performing the maintenance and inspection of the dynamic brake resistor, thereby overcoming the above-mentioned disadvantages of the prior art.
  • a forced draft cooling system for a diesel-electric locomotive having a radiator for a diesel engine disposed on a side surface of the locomotive body, a dynamic brake resistor disposed at the inner side of the radiator, and a fan for sucking in a cooling air through the radiator and the resistor, characterized in that the resistor is divided into a plurality of units, which are arranged so as to be distributed within the draft area of the radiator.
  • a main generator 2 On a locomotive body 1, a main generator 2, a diesel engine 3, and a radiator fan 4 driven through a radiator fan driving device 5 are disposed successively in the longitudinal direction of the body 1.
  • a dynamic brake resistor 7 (see Fig. 3) is disposed at the inner side of the corresponding one of radiators 6 disposed on both side surfaces of the locomotive body 1, respectively.
  • the resistor 7 is divided into a plurality of resistor units 7a, which are arranged so as to be distributed within the draft area of the corresponding radiator 6.
  • each radiator 6 is constituted by three radiator units 6a, which are divided in the widthwise direction and arranged with a gap b (generally from 1.0 to 20 mm) for draft provided between the adjacent ones. Moreover, a gap c (generally from 50 to 70 mm) for draft is provided also between the radiator units 6a and a mounting frame 8 secured to the body 1. Each radiator 6 and the corresponding dynamic brake resistor 7 are disposed in parallel with each other with.a gap H of from 50 to 300 mm provided therebetween.
  • the resistor units 7a constituting the dynamic brake resistor 7 are arranged with a gap a for draft provided therebetween, and are fixed to a lower resistor support 9a and an upper resistor support 9b, which are fixed to the body 1, through resistor supporting insulators 10 arranged such that the longitudinal axes of the insulators disposed in the upper part of the body 1 are perpendicular to the plane of the resistor 7, while the insulators disposed in the lower part of the body 1 are vertical so as to receive the load of the resistor 7.
  • This mounting structure facilitates the mounting operation inside the body 1.
  • Insulator covers 11 are provided above the supporting .insulators 10, respectively, for protection of the latter in case rain or the like enters from the upper part of the body 1.
  • Partition walls 12 for allowing the radiator room to be an independent room are disposed at the frontward and rearward portions of the body 1, respectively, and are inclined so as to taper toward the center of the radiator room in order to allow air to circulate excellently.
  • a reference numeral 14 denotes each of baffle plates for guiding the air passing through the radiator toward the resistor units 7a, while a numeral 15 designates each of holes formed in each baffle plate 15 in order to regulate air flow.
  • a fan 4 for draft is disposed in the central upper part of the body 1 and adapted to suck in a cooling air through the radiators 6 mounted on the body side surfaces and the dynamic brake resistors 7 and discharge the cooling air heated there from the body upper surface.
  • the fan 4 is driven by the diesel engine 2 through a propeller shaft 20, a gear box 21 and a vertical shaft 22.
  • the fan 4 may, as a matter of course, be driven by means of an independent drive motor.
  • Vent holes 13 for taking in a cooling air for lowering the temperature of the gear box 21 are formed in the partition wall 12 remoter from the diesel engine-3.
  • the units 7a constituting the dynamic brake resistor 7 are arranged so as to be distributed within the draft area of the radiator 6, the wind velocities within the draft area of the radiator 6 become relatively uniform, so that there will be no portion having a locally high wind velocity. Accordingly, it is possible to prevent production of vibration noises of the radiator core fins.
  • the gap b is provided between the adjacent radiator units 6a, and each resistor unit 7a is disposed so as to correspond to the gap b. Therefore, the cooling air passing through the gap b, i.e., the cooling air not heated by the radiator units 6a, is made to directly blow against the corresponding resistor unit 7a, thereby allowing the resistor units 7a to be improved in cooling efficiency.
  • each resistor unit 7a is compact and lightweight, so that. it becomes extremely easy to demount and remount the resistor units 7a in a narrow space in maintenance and inspection.
  • elements 19 shown in Fig. 6 become short in span, the sag of the elements 19 due to thermal expansion becomes small, so that there will be no short-circuit accident of the elements 19 due to sagging.
  • the air flowing in through the radiators 6 and the resistors 7 has a high temperature, since it is heated by both of them.
  • vent holes 13 formed in the partition wall 13 remoter from the diesel engine 3.
  • the vent holes 13 are adapted to allow the cooling air for cooling a compressor in a compressor room (not shown) to flow in therethrough. Thereby, the radiator room is cooled, and the above-mentioned problem can be solved.
  • the dynamic brake resistor is divided into a plurality of units and arranged so as to be distributed within the draft area of-the radiator, the wind velocities of the cooling air passing through the radiator are uniformed, so that there will be no portion having an extremely high wind velocity. Accordingly, it is possible to prevent production of vibration noises of the radiator core fins.
  • each unit is compact and lightweight. Therefore, it becomes easy to demount and remount the resistor units in maintenance and inspection and moreover, it is possible to prevent a short-circuit accident of the elements due to the sagging thereof.
