Derartige Versorgungseinheiten, welche getrennte Gebläse einerseits für die Motorkühlung, andererseits für die Generatorkühlung aufweisen und demzufolge mit getrennten Kühlluftströmen arbeiten, sind bei Notstromaggregaten oder beweglichen Stromerzeugern, z.B. für Außenarbeiten bekannt. Bekannte Aggregate dieser Art, beispielsweise nach
Ein besonderes Einsatzgebiet derartiger Versorgungseinheiten betrifft das Transportwesen, insbesondere bei LKWs, die auf langen Strecken eingesetzt werden, wobei deren Fahrerkabine zunehmend als Aufenthaltsort während längerer Fahrpausen, auch für Übernachtungen, dient. Während dieser Fahrpausen ist eine Kabinenversorgung mit elektrischer Energie zur Beleuchtung der Fahrerkabine, zum Betreiben von Klimaanlagen, Mikrowellenkochgeräten, von Apparaten der Unterhaltungselektronik und dergleichen erforderlich.A particular application of such supply units relates to the transportation, especially in trucks that are used on long distances, with the cab increasingly serves as a residence during longer breaks, even for overnight stays. During these breaks, 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.
Aus emissionstechnischen, wirtschaftlichen und auch gesetzlichen Gründen ist es nicht statthaft, die große Hauptmaschine wegen eines geringen elektrischen Leistungsbedarfs von ca. 1÷3 kW, während Park- und Ruhezeiten, zur Versorgung der Fahrerkabine laufen zu lassen. Dies gilt sinngemäß für Wohnmobile, oder behördliche und militärische Fahrzeuge aller Art.For emission, economic and legal reasons, it is not allowed to run the large main engine because of a low electrical power consumption of about 1 ÷ 3 kW, while parking and rest periods, to supply the driver's cab. This applies mutatis mutandis to campers, or official and military vehicles of all kinds.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine gekapselte Versorgungseinheit der eingangs genannten Art mit besonders kleinem Bauvolumen bei geringer Umweltbelastung zu verwirklichen und mit einer schalltechnisch besonders wirkungsvollen Kapselung zu versehen, wodurch sich besonders hohe Anforderungen an die Wirksamkeit der Innenraumkühlung der Kapsel ergeben.The present invention has for its object to realize an encapsulated supply unit of the type mentioned with a particularly small volume with low environmental impact and to provide a sound particularly effective enclosure, which results in particularly high demands on the effectiveness of the interior cooling of the capsule.
Diese Aufgabe wird erfindungsgemäß an einer Versorgungseinheit der eingangs genannten Art gemäß Patentanspruch 1 gelöst.This object is achieved by a supply unit of the type mentioned according to claim 1.
Gemäß dem Erfindungsvorschlag ist vorgesehen, dass auf der Kurbelwelle des Motors bzw. deren Verlängerung auf der Eingangsseite für die Kühlluft, wo üblicherweise das Motorgebläse sitzt, ein so genannter Doppellüfter vorgesehen ist. Dieser umfasst einen so genannten Innenlüfter, der innerhalb des Motorgehäuses angeordnet ist und somit dem Motorgebläse entspricht, sowie einen so genannten Außenlüfter, der außerhalb des Aggregatgehäuses angeordnet ist und für die Kapselkühlung auf der Außenseite des Aggregatgehäuses vorgesehen ist.According to the proposal of the invention it is provided that on the crankshaft of the engine or its extension on the input side for the cooling air, where usually the engine fan is seated, a so-called double fan is provided. This comprises a so-called internal fan, which is arranged inside the motor 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 on the outside of the unit housing.
Um eine besonders effektive Kühlung zu erzielen, sind getrennte Ansaugwege für die Kühlluft zu den beiden Lüftereinheiten vorgesehen, so dass eine optimale Mengenabstimmung für die beiden Kühlluftteilströme ermöglicht wird.In order to achieve a particularly effective cooling, separate suction paths for the cooling air to the two fan units are provided, so that an optimal quantity adjustment for the two partial cooling air streams is made possible.
Im Rahmen des erfindungsgemäßen Vorschlags ist ferner vorgesehen, dass der Strömungsweg für einen ersten Teilstrom der angesaugten Kühlluft einen ersten Zuluftkanal mit einem Rohrstutzen umfasst, der mit dem Inneren des Aggregatgehäuses benachbart dem Innenlüfter für die Aggregatkühlung verbunden ist.In the context of the proposal according to the invention it is further provided that the flow path for a first partial flow of the intake cooling air comprises a first supply air duct with a pipe socket which is connected to the interior of the unit housing adjacent the internal fan for the unit cooling.
Durch den Rohrstutzen wird dafür gesorgt, dass der vom Innenlüfter angesaugte Teilstrom auf direktem Wege in das Innere des Aggregatgehäuses gelangt und von dort zur Kühlung das gesamte Gehäuse vorbei an den heißen Motoraggregaten und auch an den Wärmequellen des Generators durchströmt.Through the pipe socket is ensured that the drawn from the inner fan partial flow passes directly into the interior of the unit housing and flows from there for cooling the entire housing past the hot engine units and also at the heat sources of the generator.

Dabei wirkt die Wand des Rohrstutzens einerseits als äußere Begrenzung des Zuluftkanals für den ersten Teilstrom, andererseits als innere Begrenzung für den Zuluftkanal des zweiten Teilstroms, d.h. beide Teilströme gelangen in getrennten Kanälen direkt vor die jeweiligen Lüfterrotoren.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, i. Both partial streams arrive in separate channels directly in front of the respective fan rotors.
Auf der Zuluftseite ist für beide Teilströme ein gemeinsamer Zuluftschacht auf der Abluftseite ist für beide Teilströme ein gemeinsamer Abluftschacht innerhalb der Kapsel vorgesehen.On the supply air side is a common supply air duct on the exhaust air side is provided for both partial flows a common exhaust duct inside the capsule for both partial flows.
Im Zuluftschacht befindet sich zweckmäßig ein Ölkühler für den Motor und/oder zu kühlende elektrische Komponenten des Stromaggregats; im Abluftschacht ist zweckmäßig der Motorschalldämpfer angeordnet, wobei weitere heiße Bauteile der Abgasführung ebenfalls im Abluftschacht Platz finden können. Wegen dieser vorteilhaften Abluftführung ist auch ein Anbau des Motorschalldämpfers direkt am Motor möglich.In Zuluftschacht 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 this advantageous exhaust air duct and an extension of the engine muffler is possible directly on the engine.
Zur optimalen Führung des Teilluftstroms für die Kapselkühlung können innerhalb der Kapsel dem Stromaggregat nahe, achsparallel verlaufende Zwischenwände zugeordnet sein, welche die Kühlluft für die Kapselkühlung kanalisieren.For optimal guidance of the partial air flow for the capsule cooling can be assigned within the capsule close to the generator, axially parallel partition walls, which channel the cooling air for the capsule cooling.
Beide Lüftereinheiten sind zweckmäßig als Radialgebläse ausgebildet, wobei der Kühlstrom des Innenlüfters das Motorgehäuse innen, der Kühlstrom des Außenlüfters die Kapsel auf der Außenseite des Aggregatgehäuses durchströmt und wobei beide Kühlströme im wesentlichen gleichgerichtet verlaufen.Both fan units are expediently designed as a radial fan, wherein the cooling flow of the inner fan, the motor housing inside, the cooling flow of the outer fan flows through the capsule on the outside of the unit housing and wherein both cooling flows are substantially rectified.
Was die Zuordnung der beiden Zuluftkanäle betrifft, so besteht eine vorteilhafte erfindungsgemäße Ausgestaltung darin, dass der erste Zuluftkanal innerhalb des zweiten angeordnet ist und dass beide Zuluftkanäle mit dem gemeinsamen Zuluftschacht verbunden sind.With regard to the assignment of the two supply air ducts, 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.
Aus Montagegründen ist es dabei zweckmäßig, dass der erste Zuluftkanal an einem getrennten von außen montierbaren Wandteil der Kapsel befestigt ist.For assembly reasons, it is expedient that the first supply air duct is attached to a separate externally mountable wall part of the capsule.
