Abstract
Description
Die Erfindung betrifft eine Verdampferanordnung zur Kühlung von einem in einem Kältegerät, wie einem Kühlschrank, einer Kühl- und Gefrierkombination oder dergleichen, angeordneten Kühlräumen, mit wenigstens zwei in Reihenschaltung hintereinander angeordneten, in einem Einkreiskältesystem liegenden Verdampfern, von welchem einer eine Kältemittel-Einspritzstelle aufweist als der andere Verdampfer, wobei die Verdampfer durch wenigstens einen Kältemittelkanal kältetechnisch miteinander verbunden sind. Eine derartige Verdampferanordnung ist aus EP-A-178 226 bekannt.The invention relates to an evaporator arrangement for cooling one in one Refrigerator, such as a refrigerator, a fridge-freezer or the like, arranged cold rooms, with at least two in series arranged evaporators located in a single-circuit cooling system, from which one has a refrigerant injection point than the other evaporator, wherein the evaporators with one another through at least one refrigerant channel are connected. Such an evaporator arrangement is known from EP-A-178 226.
Bei Kühlgeräten mit wenigstens zwei wärmeisolierend getrennt voneinander angeordneten Kühlfächern, wie beispielsweise einem Normalkühlfach und einem darunter angeordneten Tiefkühlfach oder aber einem Gefrierfach und einem darunter angeordneten Normalkühlfach, ist es Stand der Technik, den Kühlfächern zu deren Kühlung jeweils einen Verdampfer zuzuordnen, welche üblicherweise durch die Platinenabschnitte einer Verdampferplatine gebildet und in Reihenschaltung hintereinander in einem Einkreiskältesystem angeordnet sind. Die Reihenschaltung der Verdampfer ist dabei üblicherweise so bestimmt, daß der Verdampfer geringerer Kälteleistung dem Verdampfer höherer Kälteleistung nachgeschaltet ist und aus Gründen der Minimierung von Kältemittelfließstrecken zwischen den beiden Platinenabschnitten in vertikaler Richtung von unten nach oben von Kältemittel durchströmt ist. Eine derartige Durchströmung des nachgeschalteten Verdampferabschnitts bringt mit sich, daß sich innerhalb des Kühlfaches eine Temperaturschichtung ausbildet, wodurch die Temperatur im Bereich der Decke des Kühlfaches deutlich wärmer als die im Bereich des Kühlfachbodens zu messende Temperatur ist, so daß sich eine verhältnismäßig hohe Temperaturdifferenz zwischen dem deckennahen und dem bodennahen Bereich des nahme bringt jedoch nicht nur einen unerheblichen Installationsaufwand mit sich, sondern bedingt neben den Kosten für einen Ventilator, daß sich der Energieverbrauch des Gerätes durch den funktionsbedingt notwendigen ständigen Betrieb des Ventilators, in unerwünschter Weise erhöht.In cooling devices with at least two heat-insulating arranged separately from each other Cooling compartments, such as a normal refrigerator compartment and one arranged below Freezer or a freezer and one arranged below Normal cooling compartment, it is state of the art to cool the cooling compartments in each case assign an evaporator, which is usually through the circuit board sections an evaporator board formed and in series in a row Single-circuit cooling system are arranged. The evaporator is connected in series Usually determined so that the evaporator has lower cooling capacity than the evaporator higher cooling capacity is connected downstream and for reasons of minimization of refrigerant flow paths between the two circuit board sections in vertical Refrigerant flows from bottom to top. Such a flow of the downstream evaporator section entails that within the cooling compartment forms a temperature stratification, whereby the temperature in the The area of the ceiling of the refrigerator compartment is significantly warmer than that in the area of the refrigerator compartment floor temperature to be measured, so that there is a relatively high Temperature difference between the area close to the ceiling and the area near the floor However, taking not only involves an insignificant installation effort, but also In addition to the cost of a fan, the energy consumption the device due to the permanent operation of the fan, which is necessary for the function, undesirably increased.
Der Erfindung liegt die Aufgabe zugrunde, eine Verdampferanordnung gemäß dem
Oberbegriff des Anspruches 1 mit einfachen konstruktiven Maßnahmen hinsichtlich einer
zumindest annähernd gleichmäßigen Temperaturverteilung innerhalb des durch
den nachgeschalteten Verdampfer gekühlten Kühlfaches zu ertüchtigen.The invention is based, an evaporator arrangement according to the task
Preamble of
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß der Kältemittelkanal am Ende seines Verlaufes am Verdampfer mit der Einspritzstelle in den Abschnitt des zweiten Verdampfers übergeführt ist, auf welchem er den in Einbaulage obenliegenden Endabschnitt dieses Verdampfers zugeführt ist, von wo er über den Restabschnitt des zweiten Verdampfers verläuft.This object is achieved according to the invention in that the refrigerant channel on End of its course on the evaporator with the injection point in the section of the second evaporator is transferred, on which it is located in the installation position above End section of this evaporator is supplied, from where it over the remaining section of the second evaporator.
Hierdurch ist unter Vermeidung zusätzlicher, zur Kostensteigerung eines Kühlgerätes beitragende Maßnahmen, wie die Installation eines Ventilators oder dergleichen, zumindest weitestgehend eine gleichmäßige Temperaturverteilung innerhalb des Kühlraumes, wie beispielsweise eines Normalkühlfaches, erreicht und somit die Temperaturdifferenz innerhalb des Kühlfaches minimiert, da der Kältemittelkanal nach seinem Austritt aus dem Verdampfer mit der Einspritzstelle, wie beispielsweise einem Gefrierfach- oder Frischkühlfachverdampfer, unmittelbar und somit mit hoher Kälteleistung dem obenliegenden Endabschnitt des zweiten Verdampfers zugeführt ist. Aufgrund der intensiveren Kühlung ds obenliegenden Bereiches des Verdampfers erfolgt eine Unterstützung der natürlichen Konvektion und somit eine Luftdurchmischung innerhalb des vom zweiten Verdampfer gekühlten Kühlfaches, hervorgerufen durch das höhere spezifische Gewicht der Kaltluft.This avoids additional, to increase the cost of a refrigerator Contributing measures, such as installing a fan or the like, at least largely uniform temperature distribution within the cold room, such as a normal cooling compartment, and thus the temperature difference minimized within the refrigerator compartment, since the refrigerant channel after its Exit from the evaporator with the injection point, such as a freezer compartment or fresh cooling compartment evaporator, directly and thus with high cooling capacity is fed to the overhead end portion of the second evaporator. Due to the Support is provided for more intensive cooling of the overhead area of the evaporator natural convection and thus an air mixing within of the cooling compartment cooled by the second evaporator, caused by the higher one specific weight of cold air.
Nach einer besonders bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß die Verdampfer eine unterschiedliche Kälteleistung aufweisen und daß der Kältemittelkanal von dem mit der Einspritzstelle versehenen, eine höhere Kälteleistung aufweisenden Verdampfer auf den in Einbaulage obenliegenden Endabschnitt des zweiten, eine geringere Kälteleistung aufweisenden Verdampfer übergeführt ist und von diesem Endabschnitt aus über den verbleibenden Abschnitt des Verdampfers geringerer Kälteleistung verläuft. According to a particularly preferred embodiment of the subject of the invention it is provided that the evaporators have a different cooling capacity and that the refrigerant channel from the one provided with the injection point, a higher one Evaporator with cooling capacity on the top section in the installed position of the second evaporator, which has a lower cooling capacity and from this end section over the remaining section of the evaporator lower cooling capacity.
Eine besonders einfache Montage der Verdampferanordnung im Kühlgerät und zugleich eine besonders positionssichere Kanalführung zur Vermeidung einer Temperaturschichtung innerhalb der von der Verdampferanordnung zu kühlenden Kühlfläche ergibt sich, wenn nach einer bevorzugten Ausführungsform des Gegenstandes der Erfindung vorgesehen ist, daß die Verdampferanordnung als Verdampferplatine mit wenigstens zwei Platinenabschnitten unterschiedlicher Kälteleistung ausgeführt ist.A particularly simple assembly of the evaporator arrangement in the refrigerator and at the same time a particularly secure position of the duct to avoid temperature stratification within the cooling surface to be cooled by the evaporator arrangement arises if according to a preferred embodiment of the object of the invention it is provided that the evaporator arrangement as an evaporator board with at least two circuit board sections with different cooling capacities.
Gemäß einer nächsten bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß von dem Platinenabschnitt höherer Kälteleistung der Kältemittelkanal von dem Ende seiner Anordnung auf diesen Platinenabschnitt zumindest in den Nahbereich des davon abgewandten Endabschnitts des in Einbaulage der Verdampferanordnung höherliegenden Platinenabschnitts geringerer Kälteleistung übergeführt ist, von wo er zumindest annähernd mäanderartig über die verbleibende Fläche des Platinenabschnitts geringerer Kälteleistung geführt ist.According to a next preferred embodiment of the subject of the invention it is provided that the refrigerant channel has a higher cooling capacity from the circuit board section from the end of its placement on this board section at least in the vicinity of the end section facing away from it in the installed position of the evaporator arrangement Lower section of the lower cooling capacity transferred is from where it is at least approximately meandering over the remaining area of the circuit board section of lower cooling capacity.
Eine derartige Verdampferanordnung stellt für ein Kältegerät mit einem obenliegenden Normalkühlfach und einem darunter angeordneten Frischkühlfach eine zumindest annähernd gleichmäßige Temperaturverteilung im ersteren Kältefach sicher, da die mit höherem spezifischen Gewicht beaufschlagte Kaltluft eine natürliche Konvektion im Normalkühlfach hervorruft.Such an evaporator arrangement represents a refrigeration appliance with an overhead one Normal cooling compartment and a fresh cooling compartment arranged underneath one at least approximately Even temperature distribution in the first refrigeration compartment is safe, because the With a higher specific weight, cold air acted on natural convection in the Normal refrigerator compartment.
Nach einer besonders vorteilhaften Ausgestaltung des Gegenstandes der Erfindung ist vorgesehen, daß der Kältemittelkanal am Platinenabschnitt geringerer Kälteleistung an seinem dem Platinenabschnitt höherer Kälteleistung zugewandten Endabschnitt einen in seinem Verlauf gestalteten Sammler aufweist.According to a particularly advantageous embodiment of the subject of the invention provided that the refrigerant channel on the circuit board section of lower cooling capacity its end section facing the circuit board section with higher cooling capacity has collectors designed in its course.
Gemäß einer alternativen Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß der Kältemittelkanal am Platinenabschnitt geringerer Kälteleistung an dessen vom Platinenabschnitt höherer Kälteleistung abgewandten Endabschnitt im Nahbereich einer dort angeordneten Absaugstelle einen Sammler aufweist.According to an alternative embodiment of the subject matter of the invention, that the refrigerant channel on the circuit board section has a lower cooling capacity whose end section facing away from the board section of higher cooling capacity in Near a suction point arranged there has a collector.
Hierdurch ist der Weg zwischen dem Sammler und der Absaugstelle für das Kältemittel minimiert, wodurch das sich während der Stillstandszeit des Kältemittelverdichters im Sammler gesammelte Kältemittel bereits kurzzeitig unmittelbar nach Wiederanlauf des Kältemittelverdichters für den Kältekreisfauf zur Verfügung steht. This is the way between the collector and the suction point for the refrigerant minimized, which is during the downtime of the refrigerant compressor Refrigerants collected in the collector are available for a short time immediately after restart of the refrigerant compressor is available for the refrigeration circuit.
Entsprechend einer letzten bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß von dem Platinenabschnitt höherer Kälteleistung der Kältemittelkanal vom Ende seiner Anordnung auf diesem Platinenabschnitt zumindest in den Nahbereich des diesen Platinenabschnitts zugewandten Endabschnitts des in Einbaulage der Verdampferanordnung tieferliegenden Platinenabschnitts geringerer Kälteleistung übergeführt ist, von wo er zumindest annähernd mäanderartig über die verbleibende Fläche des Platinenabschnitts geringerer Kälteleistung geführt ist.According to a last preferred embodiment of the subject of the invention it is provided that the refrigerant channel has a higher cooling capacity from the circuit board section from the end of its placement on this board section at least in the near area of the end section facing this circuit board section in the installed position the evaporator arrangement of lower-lying section of the board with lower cooling capacity is transferred from where it is at least approximately meandering over the remaining one Surface of the circuit board section of lower cooling capacity is performed.
Durch eine derartige, vorteilhafterweise bei einem Kühlschrank mit einem ***-Gefrierfach und einem Normalkühlfach zum Einsatz kommenden Verdampferanordnung ist innerhalb des Normalkühlfaches eine zumindest weitestgehend gleichmäßige Temperaturverteilung erreicht, da durch die Kältemittelkanalführung der deckennahe Bereich des Normalkühlfaches stärker gekühlt ist und die mit höherem spezifischen Gewicht beaufschlagte Kaltluft eine natürliche Konvektion innerhalb des Kühlfaches hervorruft und somit die Kühlfachluft durchgemischt ist.By such a, advantageously in a refrigerator with a *** freezer and a normal cooling compartment used evaporator arrangement an at least largely uniform temperature distribution within the normal refrigerator compartment reached because the area close to the ceiling through the refrigerant duct of the normal refrigerator compartment is cooled more heavily and those with a higher specific weight cold air causes natural convection inside the refrigerator compartment and thus the refrigerator compartment air is mixed.
Die Erfindung ist der nachfolgenden Beschreibung anhand eines in der beigefügten Zeichnung vereinfacht dargestellten Ausführungsbeispiels erläutert.The invention is the following description based on one in the accompanying Drawing illustrated simplified embodiment.
Die einzige Figur zeigt in vereinfachter schematischer Darstellung eine Verdampferplatine mit zwei zusammenhängenden, einem Normalkühlfach und einem Tiefkühlfach zuordenbaren Verdampferabschnitt.The single figure shows a simplified schematic representation of an evaporator board with two connected, a normal freezer and a freezer assignable evaporator section.

zum Einsatz in einem Kühlgerät mit einem Normalkühlfach und einem
Frischkühlfach geeignete Verdampferplatine 10 gezeigt, welche einen ersten, beispielsweise
zur Kühlung eines Frischkühlfaches bestimmten Platinenabschnitt 11 aufweist,
dessen Platinenfläche 12 von einem von unten nach oben mäanderartig verlaufenden
Kältemittelkanal 13 überzogen ist, welcher ausgehend von einer Drosselstelle
14 auf einem Verbindungssteg 15 zuflußseitig an den Platinenabschnitt 11 herangeführt
und auf diesem zunächst an das in Einbaulage tieferliegende, vom Verbindungssteg
15 abgewandte Ende der Platinenfläche 12 verläuft. Von diesem unteren Ende ist
der Kältemittelkanal 13 wie bereits erwähnt mäanderartig nach oben an den dem Verbindungssteg
15 zugewandten Endabschnitt der Platinenfläche 12 geführt, von wo er
dann über den Verbindungssteg 15 einem zweiten, beispielsweise zur Kühlung eines
Normalkühlfaches dienenden Platinenabschnittes 16 zugeführt ist. Nach seinem Zutritt
zu dem Platinenabschnitt 16 ist dieser über dessen Platinenfläche 17 unmittelbar in
den oberen, vom Platinenabschnitt 11 abgewandten Endabschnitt A übergeführt. Von
diesem in Einbaulage der Verdampferplatine 10 in einem nicht dargestellten Kühlgerät
obenliegenden Endabschnitt A verläuft, der Kältemittelkanal 13 mäanderartig über die
verbleibende Restfläche B an das dem Platinenabschnitt 11 zugewandte Ende des
Platinenabschnitts 16. Hier ist in den Kältemittelkanal 13 ein Sammler 18 geschaltet,
von dessen abflußseitigem Ende aus der Kältemittelkanal 13 wieder in den oberen Endabschnitt
A des Platinenabschnitts 11 übergeführt und von dort an eine auf dem beide
Platinenabschnitte 11 und 16 miteinander verbindenden Verbindungssteg 15 liegende
Ansaugstelle 19 herangeführt ist.In the figure shown is a roll-bond process, for example
for use in a refrigerator with a normal refrigerator compartment and a
Fresh cooler suitable evaporator board 10 shown, which a first, for example
has

Hierbei ist der dem Kühlfach zugeordnete platinenartige Verdampfer wiederum an seinem der Decke des Kühlfaches zugewandten Endabschnitts bevorzugt gekühlt, um einer Temperaturschichtung innerhalb des Kühlfaches zumindest weitestgehend entgegenzutreten und die aufgrund der spezifisch schwereren Kaltluft auftretende natürliche Konvektion zu unterstützen.The invention differs from the exemplary embodiment described above also to form one with a fridge and freezer combination, for example a wire tube evaporator for the freezer compartment and a circuit board evaporator for the Cooling compartment can be used. Here is the board-like evaporator assigned to the refrigerator compartment again at its end section facing the ceiling of the refrigerator compartment preferably cooled to at least a temperature stratification within the refrigerator compartment to oppose as far as possible and because of the specifically heavier To support cold air occurring natural convection.
