Abstract
Description
Titel: Abwärmenutzung an ElektromaschinenTitle: Use of waste heat in electrical machines
Bezeichnung: " Wärme falle zur Nutzung der Verlustwärme an Feldwicklungen von Elektromaschinen, ins -besondere Verdichtermotore für Wärmepumpen -betrieb." Anwendungsgebiet: Die Erfindung betrifft die Anwendung von ineinandergeschobenen Töpfen, die einen ge -schlossenen Hohlraum zur Aufnahme des Wärme -trägers bilden. Der Einsatz erfolgt an Elektro -maschinen, insbesondere an Motoren zum Antrieb von Verdichtern und Pumpen in Kälte - und M;ärmepumpanlagen.Designation: "Heat falls to use the heat lost on field windings of electrical machines, especially compressor motors for heat pump operation. " Field of application: The invention relates to the use of nested Pots that form a closed cavity to accommodate the heat carrier. It is used on electrical machines, in particular on motors for driving Compressors and pumps in refrigeration and heat pump systems.
Zweck: Gegenwärtig rJird die Abwärme der Feldwicklungen nicht direkt genutzt und technisch nur der aus -reichenden Kühlung hinreichende Aufmerksamkeit gewidmet. Zweck der nachstehenden Erfindung ist die direkte und nahezu vollständige Nutzung der Abwärme.Purpose: At present, the waste heat from the field windings is not direct used and technically enough attention only to sufficient cooling dedicated. The purpose of the invention below is to be straightforward and almost complete Use of waste heat.
Aufgabe: Die Aufgabe des Gegenstandes der Erfindung ist die direkte Nutzung der Wicklungsabwärme über einen als Wärme falle ausgebildeten Apparat. Da die Kühlung der 'iicklungen unbedingt erforder -lich ist, ist es die Aufgabe der nachstehend beschriebenen Erfindung, die Kühlung von Motoren im Heizungsbetrieb sinnvoll so vorzunehmen, daß die Abwärme der Wicklungen direkt an den Hei -zungskreislauf, auf dem Temperaturniveau des Warmwasserkreislaufs abgegeben wird. Insbesondere sollen die Kompressorantriebsmotore für Wärme -pumpen mit Wärmefallen, anstelle der Kühlfinnen -gehäuse für Luftkühlung, versehen werden.Task: The task of the subject of the invention is the direct one Use of the waste heat from the winding via an apparatus designed as a heat trap. There the cooling of the windings is absolutely necessary, it is the task of the Invention described below, the cooling of engines in heating mode make sense in such a way that the waste heat from the windings goes directly to the heating circuit, is released at the temperature level of the hot water circuit. In particular, should the compressor drive motors for heat pumps with heat traps instead of the cooling fins housing for air cooling.
Dem Anteil einer ca. 10 - 15 °% - igen Abwärme und deren direkten Nutzung in Heizsystemen muß aus Gründen der Energiepreissteigerung und Roh -stoffverknappung große Bedeutung beigemessen werden. The proportion of approx. 10 - 15% waste heat and its direct Use in heating systems has to be due to the increase in energy prices and scarcity of raw materials great importance should be attached.
Lösung: Dies wird erfindungsgemäß dadurch erreicht, daß das Feldpaket mit Wicklung im Inneren eines topfartigen Apparates derart untergebracht ist, daß das Paket saugend an die Topfwandung ange -lagert ( eingepreßt ) ist und somit in der Lage ist, seine Wärme direkt durch die Topfwandung hindurch an das Wärmeträgermedium abgeben zu können. Durch Anwendung eines weiteren topfartige Apparats, der übergestülpt wird, entsteht zwischen topfartigen Apparaten ein topfförmiger Hohlraum. Durch entsprechende Bemessung ist dieser Hohlraum als Spaltraum ausgebildet. Ein zentraler Eintrittsstutzen am Topfboden sorgt für eine radiale gleichmäßige, räumlich glockenförmige Verteilung des Wärmeträgermediums.Solution: According to the invention, this is achieved in that the field packet is housed with winding inside a pot-like apparatus that the package is sucked onto the wall of the pot (pressed in) and thus in is able to transfer its heat directly through the pot wall to the heat transfer medium to be able to deliver. By using another pot-like device that is slipped over a pot-shaped cavity is created between pot-like devices. Through appropriate Dimensioning, this cavity is designed as a gap. A central inlet nozzle at the bottom of the pot ensures a radially even, spatially bell-shaped distribution of the heat transfer medium.
Die Sicherstellung dieses Strömungsverhaltens wird zusätzlich durch einen Zentrier - und Ausgleichsring für Druckdifferenzen sowie durch einen Ringkanal erreicht, aus dem das Medium aus tritt. Ensuring this flow behavior is additionally through a centering and compensating ring for pressure differences and an annular channel from which the medium emerges.
Vorteil: Der Vorteil des Gegenstandes der Erfindung be -steht darin, daß der Wärmeentzug aus dem Feld -paket direkt erfolgt unter Ausnutzung geringer Materialstärken und günstiger Strömungs -geschwindigkeit im Medium mit dem Ergebnis eines geringen Wärmedurchgangswiderstandes, hoher Nutzungstemparaturen und günstiger Betriebs -bedingungen für die Wicklung.Advantage: The advantage of the subject matter of the invention is that that the heat extraction from the field -package takes place directly using less Material thicknesses and favorable flow velocity in the medium with the result a low heat transfer resistance, high usage temperatures and cheaper Operating conditions for the winding.
Durch die weitestgehend radialsymetrische Ge -staltung der Apparate wird eine gleichmäßige Wärmeentzugsdichte erreicht. Due to the largely radially symmetrical design of the apparatus a uniform heat extraction density is achieved.
Beschreibung Der Gegenstand der Erfindung besteht aus zwei übereinandergeschobenen topfartigen Apparaten ( 1 Fig. 1 ) und ( 2 Fig. 1 ). Description The subject of the invention consists of two superimposed pot-like apparatus (1 Fig. 1) and (2 Fig. 1).
Am äußeren Topf ( 1 Fig. 1 ) ist der Eintrittsstutzen ( 3 Fig. 1 ) zentral angeordnet. Die Böden beider Töpfe ( 1 Fig. 1 ) und ( 2 Fig, 1 ) sind klöpperartig ausgeformt. Der äußere Topf C 1 Fig. 1) ist in seiner Randzone ( 4 Fig. 1 ) so gestaltet, daß sich beim Ineinanderfügen beider Töpfe der Sammelkanal ( 5 Fig. 1 ) bildet.On the outer pot (1 Fig. 1) is the inlet nozzle (3 Fig. 1) centrally arranged. The bottoms of both pots (1 Fig. 1) and (2 Fig, 1) are dished shaped. The outer pot C 1 Fig. 1) is designed in its edge zone (4 Fig. 1) so that when the two pots are inserted into one another, the collecting channel (5 Fig. 1) is formed.
Am Innentopf ( 2 Fig. 1 ) ist der Unterrand ( 6 Fig. 1 ) kegelförmig angeformt, daß der aufzuschrumpfende Ausgleichsring ( 7 Fig. 1 ) in seiner Lage fixiert wird. Zwischen Topf ( 1 Fig. 1 ) und Topf ( 2 Fig. 1 ) befindet sich in der Randzone ein umlaufender Dichtring ( 8 Fig. 1 ). Die Töpfe ( 1 Fig. 1 ) und ( 2 Fig. 1 ) werden mit Hilfe der Schrauben ( 9 Fig. 1 ) verschraubt.On the inner pot (2 Fig. 1) the lower edge (6 Fig. 1) is conical integrally formed that the compensating ring to be shrunk (7 Fig. 1) in its position is fixed. Between the pot (1 Fig. 1) and the pot (2 Fig. 1) is located in the edge zone a circumferential sealing ring (8 Fig. 1). The pots (1 Fig. 1) and (2 Fig. 1) are screwed with the help of the screws (9 Fig. 1).
In der Randzone am Topf ( 1 Fig. 1 ) ist der Austrittsstutzen ( 10 Fig. 1 ) am Ringkanal ( 5 Fig. 1 ) angebracht.In the edge zone on the pot (1 Fig. 1) is the outlet nozzle (10 Fig. 1) attached to the ring channel (5 Fig. 1).
Der in Figur 2 dargestellte Ausgleichsring ( 7 Fig 1 ) trägt an seiner Innenseite Kerben ( 1 Fig. 2 ), die Durchpt anäle darstellen.The compensating ring shown in Figure 2 (7 Fig 1) carries on his Inside notches (1 Fig. 2), which represent throughpt anals.
Ihre Abstände entsprechen den Erfordernissen nach dem Ausgleich der räumlichen Druckverhältnisse im Spaltraum ( 11 Fig. 1 ) sowie im Sammelkanal ( 5 Fig. 1 ).Their distances correspond to the requirements for balancing the spatial pressure conditions in the gap (11 Fig. 1) and in the collecting duct (5 Fig. 1).
