Description
Elektrothermischer mit Peltierelementen arbeitender Kühlbehälter. Die Erfindung betrifft einen elektrothermischen mit Peltierelementen arbeitenden Kühlbehälter, bei dem eine durch einen Elektromotor angetriebene Pumpe ein Kühlmittel für die Peltierelemente umwälzt und bei dem Maßnahmen vorgesehen sind, die beim Ausschalten der Umwälzpumpe auf den Wärmerückfluß einwirken.Electrothermal cooling tank working with Peltier elements. The invention relates to an electrothermal Peltier element Cooling container in which a pump driven by an electric motor supplies a coolant circulates for the Peltier elements and in which measures are provided that in the Switch off the circulation pump and act on the heat return.
Es ist bei derartigen Kühlbehältern bekannt, die wärmeabgebenden Teile der Peltierelemente durch eine Kühlflüssig-, keit zu kühlen, die wiederum durch einen Luftstrom rückgekühlt wird. Das Flüssigkeitskühlsystem bildet einen geschlossenen Kreislauf, in dem die Kühlflüssigkeit durch eine Pumpe ständig umgewälzt wird. Eine derartige Anordnung hat den Nachteil, daß bei willkürlicher Abschaltung der elektrothermischen Kühlung oder bei Stromausfall durch die Kühlrohre Wärme in den Kühlraum geleitet wird.It is known in such cooling containers, the heat-emitting parts the Peltier elements through a cooling liquid, which in turn cools through an air stream is re-cooled. The liquid cooling system forms a closed one Circuit in which the coolant is constantly circulated by a pump. One Such an arrangement has the disadvantage that with arbitrary disconnection of the electrothermal Cooling or, in the event of a power failure, heat is passed through the cooling pipes into the cold room will.
Bei einer bekannten Vorrichtung (vgl. das deutsche Gebrauchsmuster ? 890 239) sind Maßnahmen getroffen, die beim Ausschalten einen Wärmerückstau in den Kühlraum verhindern sollen.Hierzu sind in den Strömungskanälen ein oder mehrere thermisch isolierende Verschlußglieder vorgesehen, mittels derer der oder die Strömungskanäle beiWAusschalten der Vorrichtung abgeschlossen werden. Solche Verschlußglieder stellen einen großen Bauaufwand dar und benötigen verhältnismäßig viel Energie. Auch die Betriebssicherheit wird durch-solche Ventile beeinträchtigt. Der Erfinder hat sich die Aufgabe gestellt, einen Kühlbehälter zu schaffen, bei dem die Prachteile der bekannten Vorrichtung vermieden werden.In a known device (see. The German utility model ? 890 239), measures have been taken to prevent heat accumulating in the to prevent the cooling space. There are one or more in the flow channels for this purpose thermally insulating closure members are provided, by means of which the flow channel or channels be completed when the device is turned off. Provide such locking links represent a major construction effort and require a relatively large amount of energy. Also the Operational safety is impaired by such valves. Of the The inventor has set himself the task of creating a cooling container in which the best parts of the known device are avoided.
Nach der Erfindung werden diese Nachteile dadurch vermieden, daß die ohne Ventil arbeitende Umwälzpumpe unterhalb der Peltierniemente angeordnet ist und ihre Leitungen zumindest im Bereich der Peltierelemente aus schlecht wärmeleitendem Material bestehen, so daß beim Stillsetzer. der Pumpe eine unbehinderte Entleerung der Leitungen in den Sammelbehälter erfolgt, ohne daß noch eine erhebliche Wärmemenge, die in den Kühlraum gelangen könnte, zurückbleibt.According to the invention, these disadvantages are avoided in that the without a valve working circulation pump is arranged below the Peltierniemente and their lines, at least in the area of the Peltier elements, made of poorly heat-conducting Material exist, so that the shutdown. unhindered emptying of the pump of the lines in the collecting tank takes place without a significant amount of heat, which could get into the refrigerator compartment remains.
Die Erfindung ist in einem Schnitt durch einen Kühlbehälter beispielsweise dargestellt.The invention is for example in a section through a cooling container shown.
In dem mit einer wärmeisolierenden Schicht 2, z.B. aus Styropor, ausgekleideten Kühlraum 3 sind auf der kupfernen Bodenplatte mehrere Blutkonservenflaschen 4 untergebracht. Der Boden des Kühlraumes besteht aus einer vernickelten Kupferplatte 5, unter der sich Peltierelemente 6 befinden, deren warme Lötstellen in bekannter Weise von Kühlkanälen durchzogen sind. Die Anschlußstellen dieser Kühlkanäle stehen durch eine Kunststoffleitung 7 einerseits mit einer elektrischen Pumpe 8 in Verbindung, die Kühlflüssigkeit aus dem Sammelbehälter 9 ansaugt. Nach Passieren der Peltierelemente und der Kunststoffleitung 10 durchläuft das Kühlmedium einen nicht dargestellten Wärmeaustauscher, dessen Kühlrippen in bekannter ',eise mittels eines kleinen Gebläses durch einen Luftstrom gekühlt werden. Vom Wärmetauscher führt die Leitung 11 in den Sammelbehälter 9. Die Stromversorgung für den Pumpenmotor 12 ist mit der Stromversorgung für die Peltierelemente gekoppelt. Im Falle einer Unterbrechung dieser Stromzufuhr wird somit die Pumpe 8 außer Betrieb gesetzt und die Kühlflüssigkeit in den Sammelbehälter 9 entleert. Der Kühlraum 3 stellt dann ein nach außen gut isoliertes System dar, da durch die Kunststoffschläuche 7,10 nur ein geringer Wärmetransport stattfindet.In the cooling space 3, which is lined with a heat-insulating layer 2, for example made of Styrofoam, several blood bottles 4 are accommodated on the copper base plate. The bottom of the cooling space consists of a nickel-plated copper plate 5, under which there are Peltier elements 6, the warm soldering points of which are traversed by cooling channels in a known manner. The connection points of these cooling channels are connected by a plastic line 7 on the one hand to an electric pump 8 which sucks in cooling liquid from the collecting container 9. After passing the Peltier elements and the plastic line 10, the cooling medium runs through a heat exchanger, not shown, the cooling fins of which are cooled in a known manner by means of a small fan by means of an air stream. The line 11 leads from the heat exchanger into the collecting container 9. The power supply for the pump motor 12 is coupled to the power supply for the Peltier elements. In the event of an interruption of this power supply, the pump 8 is therefore put out of operation and the cooling liquid is emptied into the collecting container 9. The cooling space 3 then represents a system that is well insulated from the outside, since only a small amount of heat is transported through the plastic hoses 7, 10.
