Definitions

  • the present invention relates to a compact generator intended in particular, but not exclusively, for maintenance operations on aircraft.
  • Patent FR-A-2 335 815 discloses a compact generator comprising, inside a casing, mounted on a movable chassis, a generator coupled to a combustion engine, the generator and the engine being connected by a housing surrounding the coupling, a ventilation wheel being placed inside said housing and driven indirectly by the engine and disposed between the generator and said engine so as to produce a forced circulation.
  • the whole group is ventilated by a first flow 70, 71 of pulsed air by a fan 36 essentially intended for the engine and a second flow 69, 69 'and 68 intended for its part for cooling the generator.
  • a third auxiliary flow 66 ′, 67 which ventilates the interior of the box containing the group and helps exhaust from the rear of the second flow.
  • the subject of the present invention is a compact generator which allows easy air circulation in a limited volume of air, which is simpler to produce.
  • the compact generator set constituted inside a casing mounted on a movable chassis, by an alternator coupled to an internal combustion engine and comprising a main cooling circuit for the engine including a fan and a radiator, and a secondary cooling circuit for the alternator, is characterized in that, said cooling circuits being of substantially parallel flow, the secondary circuit comprises a pipe surrounding the coupling, a ventilation wheel placed inside said pipe and driven by the engine and arranged between the alternator and said engine, so as to produce a forced circulation, and conduits connected to distribution boxes arranged on either side of the engine and open at their lower part.
  • the secondary circuit comprises a pipe surrounding the coupling, a ventilation wheel placed inside said pipe and driven by the engine and arranged between the alternator and said engine, so as to produce a forced circulation, and conduits connected to distribution boxes arranged on either side of the engine and open at their lower part.
  • FIGS. 1 and 2 it can be seen that the frame 1 rests on the ground by means of a steerable front wheel set 2 and a rear set of wheels 3.
  • the frame 1 is monocoque and closed in its part upper by shells 4 advantageously in reinforced polyester, which makes it possible to save weight.
  • an alternator 5 mechanically coupled to a motor 6: The cooling air is sucked in through an orifice 7 located at the rear of the group and discharged by a hopper 8.
  • the alternator 5 preferably made of a light alloy such as zamac, is surrounded on the one hand by a control console 9 and on the other hand by a fuel tank 10.
  • a battery 11 allows the group to start.
  • the engine 6 is an engine of the type used in the automotive industry and it is connected to an air filter 12 and to a cooling circuit comprising a radiator 13 and an expansion tank 14, the gases burned by the engine being evacuated by a pipe 15 connected to an exhaust pipe 16 placed at the bottom of the group.
  • a regulator 17 and a control box 18 of the alternator making it possible to control the voltage, the speed and the frequency of the current generated by the alternator.
  • Various elements are also attached to the chassis allowing the group to be maneuvered, such as the drawbar 19 and the towing hook 20.
  • the alternator 5 and the engine 6 are connected by a pipe 21.
  • the air enters by a grid 22 located at the rear part of 1 alternator and, after passage of the latter, arrives in a lantern 23 comprising a turbine (not shown) driven by the engine and which expels the air in pipes'24 connected to distribution boxes 25 from which the air is expelled downwards as indicated by the arrows F, in FIG. 3.
  • a lantern 23 comprising a turbine (not shown) driven by the engine and which expels the air in pipes'24 connected to distribution boxes 25 from which the air is expelled downwards as indicated by the arrows F, in FIG. 3.
  • the normal cooling circuit by fan and radiator thereby obtains better efficiency.
  • This forced circulation is, so to speak, mounted in parallel on the normal ventilation circuit which is symbolized in FIG. 4 by the arrows F 2 .
  • the normal ventilation circuit comprises, in addition to the ventilation hopper 8, a silencer (sound trap) 26 allowing the personnel to work in tolerable acoustic conditions and a radiator
