Definitions

  • the invention relates to a supply unit with a motor-generator unit as a power generator, in particular for the construction of trucks, campers, governmental and military vehicles of all kinds for electrical supply to the driver's cab, wherein the generator is enclosed by a sound-absorbing capsule, which is a Zu Kunststoffschacht for cooling air and an exhaust duct for exhaust air and wherein the cooling air is sucked by means of a fan assembly on the motor shaft.
  • Trucks are increasingly used on long journeys and thus their cab increasingly serves as a place to stay during longer driving breaks, even for overnight stays.
  • a cabin supply of electrical energy is required for the illumination of the driver's cab, for the operation of air conditioners, microwave cooking appliances, consumer electronics and the like.
  • the present invention has for its object to realize a supply unit of the type mentioned with a particularly small volume and to provide a sound particularly effective enclosure, which results in particularly high demands on the effectiveness of the interior cooling of the capsule.
  • the fan assembly comprises at least two separate fan units, namely an internal fan for the unit cooling within a housing for the generator and an external fan for the capsule cooling outside of the unit housing, and that separate intake of the Cooling air are provided for both fan units.
  • a so-called double fan is provided on the crankshaft of the engine or its extension on the input side for the cooling air, where usually the engine fan is seated.
  • This comprises a so-called internal fan, which is arranged inside the motor housing (air guide housing) and thus corresponds to the motor fan, and a so-called external fan, which is arranged outside of the unit housing and is provided for the capsule cooling in the cavity between the unit housing and the capsule inner wall.
  • two similar fans each in the form of a radial fan in question, the rotors are driven by the crankshaft speed.
  • the flow path for a first partial flow of the sucked cooling air comprises a first supply air duct with a pipe socket which is connected to a central intake opening in the end wall of the unit housing adjacent to the internal fan for the unit cooling.
  • a second supply air duct is advantageously provided as a flow path for a second partial flow of the sucked cooling air, which comprises a wall opening, which is arranged close to the outer fan for the capsule cooling.
  • the pipe socket of the first supply air duct runs in the axial direction of the power unit within the wall opening of the second supply air duct and within the central intake opening of the outdoor fan.
  • the wall of the pipe socket acts on the one hand as an outer boundary of the supply air duct for the first partial flow, on the other hand as an inner boundary for the supply air duct of the second partial flow, ie both partial flows arrive in separate channels directly in front of the respective fan rotors.
  • a common supply air shaft is provided for both partial flows; on the exhaust side, a common exhaust duct is provided within the capsule for both partial flows.
  • Zu Kunststoffschacht is conveniently an oil cooler for the engine and / or to be cooled electrical components of the generator; in the exhaust duct the engine muffler is expediently arranged, with other hot components of the exhaust system can also find room in the exhaust duct. Because of the advantageous exhaust air duct, it is also possible to mount the engine silencer directly on the engine.
  • both fan units are expediently designed as radial fans, the cooling flow of the interior fan passing through the motor housing on the inside, the cooling flow of the external fan overflowing the unit housing on the outside, and both cooling streams being substantially rectified.
  • an advantageous embodiment according to the invention is that the first supply air duct is within the is arranged second and that both supply air ducts are connected to the common supply air shaft.
  • the first supply air duct is attached to a separate externally mountable wall part of the capsule.
  • the complete supply unit according to the FIGS. 1 and 2 is installed in a closed capsule 1 whose walls are made of sheet steel with an insulating layer (not shown) on the inside.
  • the unit housing 3 is relatively closely clad by intermediate walls, namely a bottom 6 of the suction duct 22a, a left short side wall 8 above the unit housing 3 and a lower bottom wall 9, also shown in section.
  • further intermediate walls can be provided on the front and back to additionally channel the cooling air, wherein the intermediate walls below the unit housing 3 to an exhaust duct 10 are open.
  • the exhaust duct 10 is the housing interior limited by a lateral partition 11. Between this and the left capsule wall 12, the exhaust air rises and exits the exhaust duct 10 through the exhaust grille 13th
  • a supply air duct 15 with a supply air grid 16 On the supply air side is located above a floor panel 14, a supply air duct 15 with a supply air grid 16. The sucked from the surrounding supply air is sucked by a double fan assembly consisting of an external fan 17 and a dashed lines, arranged inside the unit housing 3 inside fan 18.
  • the inner fan 18 is connected with its central intake bore via a pipe socket 19 with a first supply air duct 20 with side wall 20 a, which is open to the intake duct 15.
  • the outdoor fan 17 is connected via a wall opening 21 with a second supply air duct 22, which also opens into the supply air duct 15.
  • a first partial flow according to arrow 24 flows through the first supply air duct 20 and further through the pipe socket 19 into the interior of the unit housing 3 and of there continue on the aggregates of the diesel engine 4 and those of the generator 5 down. He exits as warmed up exhaust air according to arrow 25 on the underside of the unit housing 3 and leaves from there via the exhaust duct 10 and through the exhaust grille 13, the capsule.
  • a second partial flow according to arrow 26 flows through the second supply air duct 22 and passes through the opening 21 in the bottom plate in front of the suction opening of the outer fan 17. This generates a radial air flow on the top of the unit housing 3, from where the second partial flow through the lateral partitions according to Arrows 27, 28 is deflected down to flow on the outer sides of the unit housing 3 down and passes from there according to arrows 29 also in the exhaust duct 10, where the second partial flow combined with the first partial flow and as exhaust air through the exhaust grille 13 exit.
  • the first supply air duct 20 is formed with its channel walls on the underside of a removable housing plate 30. When the housing plate 30 is mounted, the first supply air duct 20 is located within the housing walls of the second supply air duct 22, through which the second partial flow according to arrows 26 flows.
