Description

Transport-und AufbeWährungseinrichtung für thermόsensibleTransport and storage facility for thermόsensible
ProdukteProducts
Die Erfindung bezieht sich auf eine Transport- und Aufbewahrungs¬ einrichtung für thermosensible Produkte, bei welcher ein oder mehrere Peltierelemente zur Temperierung des Aufbewahrungsraumes vorgesehen sind, wobei an der aufbewahrungsraumseitigen Platte des bzw. der Peltierelemente rohrartige ärmeleitkörper oder ein einteiliger Wärmeleitformkörper vorgesehen sind und wobei die gehäuseseitige Platte des bzw. der Peltierelemente durch Rippen- wär etauschkörper gebildet ist.The invention relates to a transport and storage device for thermosensitive products, in which one or more Peltier elements are provided for the temperature control of the storage space, tubular sleeve-shaped or a one-piece heat-conducting body being provided on the storage space-side plate of the Peltier element or elements, and wherein the plate on the housing of the Peltier element or elements is formed by rib heat exchange body.
Es handelt sich dabei insbesondere um einen Transport- und Aufbe¬ wahrungsbehälter für Pharmazeutika oder dergleichen, wobei derar¬ tige Behälter bei Umgebungstemperaturen von +40°C bis 20°C ohne bewegte Teile arbeiten sollen.It is in particular a transport and storage container for pharmaceuticals or the like, such containers being intended to work without moving parts at ambient temperatures of + 40 ° C. to 20 ° C.
Zur Temperierung des Aufbewahrungsraumes werden bei der Gattung des Erfindungsgegenstandes ein oder mehrere Peltierelemente ver¬ wendet, wobei beim Einsatz mehrerer derartiger Elemente dieselben kaskadenförmig hintereinandergeschaltet sind. Die Wirkung derar¬ tiger Peltierelemente ist bekanntermaßen derart, daß bei Anlegen einer Gleichspannung an ein Peltierelement dieses Wärme von einer Seite des Elementes abzieht und zur anderen Seite des Peltierele- mentes transportiert. Beim Wechsel der Richtung des Stromflusses ändert sich auch die Richtung des Wärmetransportes, so daß mit¬ tels ein und desselben Peltierelementes der Aufbewahrungsraum entweder gekühlt oder beheizt werden kann.To temper the storage space, one or more Peltier elements are used in the category of the subject matter of the invention, the same being cascaded in series when a plurality of such elements are used. The effect of such Peltier elements is known to be such that when a DC voltage is applied to a Peltier element, this heat is drawn from one side of the element and transported to the other side of the Peltier element. When the direction of the current flow changes, the direction of the heat transfer also changes, so that the storage space can be either cooled or heated by means of one and the same Peltier element.
Es ist dabei bereits bekannt, derartige peltierelemente zur Kühlung von Kühlboxen, die für Camping und Autofahrten gedacht rungsrau seitigen Platte des Peltierelementes rohrartige Wärme¬ leitformkörper vorzusehen.It is already known to use such peltier elements for cooling cool boxes intended for camping and car trips Rough rough side plate of the Peltier element to provide tubular heat-conducting molded body.
Der Erfindung liegt die Aufgabe zugrunde, Innerhalb des Aufbewah¬ rungsraumes eine möglichst homogene Temperaturableitung zu er- ziehlen, wobei innerhalb des Aufbewahrungsraumes nahezu kein Temperaturgradient vorhanden sein soll, um hinsichtlich des ge¬ samten Inhaltes des Aufbewahrungsraumes gleiche Temperaturver¬ hältnisse zu erziehlen.The invention is based on the object of achieving as homogeneous a temperature dissipation as possible within the storage space, wherein there should be almost no temperature gradient within the storage space in order to achieve the same temperature conditions with regard to the entire contents of the storage space.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die rohr¬ artigen Wärmeleitkörper 3, die unmittelbar aneinanderliegend die Innenseite des Aufbewahrungsraumes bilden, prismatische, insbe¬ sondere viereckigen Querschnitt aufweisende, hohle Formkörper aus gut wärmeleitendem Material sind oder daß ein einteiliger Wärme¬ leitformkörper 17 aus gut wärmeleitendem Material oder daß ein einteiliger Formkörper mit integrierter Wärmeverteilzone 19 aus gut wärmeleitendem Material die Innenseite des Aufbewahrungsrau¬ mes 2 bildet. Dadurch wird einerseits eine besonders gute Wärme¬ ableitung zwischen Peltierelement 1 und Aufbewahrungsraum er- ziehlt, wobei die Innenseite des Aufbewahrungsraumes vom Peltier¬ element so weit distanziert ist, daß es zu keiner Schädigung des aufbewahrten Gutes zufolge örtlicher Unterkühlung bzw. bei Erwär¬ mung, zu örtlicher Erhitzung desselben führen kann.According to the invention, this object is achieved in that the tubular heat-conducting bodies 3, which form the inner side of the storage space directly adjacent to one another, are prismatic, in particular quadrangular cross-section, hollow shaped bodies made of good heat-conducting material or that a one-piece heat-conducting shaped body 17 is made of good material heat-conducting material or that a one-piece molded body with an integrated heat distribution zone 19 made of heat-conducting material forms the inside of the storage space 2. On the one hand, this results in particularly good heat dissipation between the Peltier element 1 and the storage space, the inside of the storage space being so far removed from the Peltier element that there is no damage to the stored goods due to local hypothermia or when heated, can lead to local heating of the same.
Vorteilhafterweise können an den äußersten röhrartigen Wärmeleit¬ körpern 3 oder an den äußeren Seitenflächen des einteiligen Wärmeleitformkörpers 17 oder an den äußeren Seitenflächen des einteiligen Formkörpers mit integrierter Wärmeverteilzone 19 die gleichfalls aus gut wärmeleitendem Material gefertigten Wandungen 7 des Aufbewahrungsraumes 2 mittels schrauben, Blindnieten oder dergleichen oder mittels wärmeleitendem Klebstoff befestigt sein. Diese Ausbildung des Aufbewahrungsraumes bewirkt eine rasche Wärmeableitung bzw. bei Heizbetrieb eine rasche Wärmezuleitung, wobei über die äußersten rohrartigen Wärmeleitkörper 3 oder über die äußeren Seitenflächen des einteiligen Wärmeleitformkörpers 17 oder über die äußeren Seitenflächen des einteiligen Formkörpers mit integrierter Wärmeverteilzone 19 eine gute Wärmeübertragung auf die Wandungen 7 des Aufbewahrungsraumes 2 erziehlt wird, wodurch die gesamten Wandungen des Aufbewahrungsraumes für die Wärmeübertragung zur Verfügung stehen.Advantageously, on the outermost tubular heat-conducting bodies 3 or on the outer side faces of the one-piece heat-conducting molded body 17 or on the outer side surfaces of the one-piece molded body with integrated heat distribution zone 19 walls 7 of the storage space 2 also made of good heat-conducting material can be fastened by means of screws, blind rivets or the like or by means of heat-conducting adhesive. This design of the storage space causes rapid heat dissipation or, in the case of heating operation, rapid heat supply, with good heat transfer to the walls via the outermost tubular heat-conducting body 3 or via the outer side surfaces of the one-piece heat-conducting molded body 17 or via the outer side surfaces of the one-piece molded body with integrated heat distribution zone 19 7 of the storage room 2 is educated, whereby the entire walls of the storage room are available for heat transfer.
Dabei können die rohrartigen Wärmeleitkörper oder der einteilige Wärmeleitformkörper mittels Klemmschienen 5 mit der aufbewah- rungsraumseitigen Platte des Peltierelementes 1 verspannt sein. Zwischen den rohrartigen Wärmeleitkörpern 3 oder dem einteiligen Wärmeleitformkörper 17 kann eine Wärmeverteilplatte 18 zwischen¬ gelegt sein, wodurch eine besonders gleichmäßige Wärmeverteilung über die Wandungen 7 des Aufbewahrungsraumes 2 erreicht wird. Diese Wärmeverteilplatte kann in den einteiligen Wärmeformkörper 17 integriert sein, wodurch ein derartiger einteiliger Formkörper mit integrierter Wärmeverteilzone 19 alleine die Wärmeverteilung und -leitung zwischen dem Peltierelement 1 und den Wandungen 7 des Aufbewahrungsraumes 2 übernimmt.The tubular heat-conducting body or the one-piece heat-conducting molded body can be clamped to the storage space-side plate of the Peltier element 1 by means of clamping rails 5. A heat distribution plate 18 can be interposed between the tubular heat-conducting bodies 3 or the one-piece heat-conducting molded body 17, as a result of which a particularly uniform heat distribution over the walls 7 of the storage space 2 is achieved. This heat distribution plate can be integrated into the one-piece molded heat body 17, as a result of which such a one-piece molded body with an integrated heat distribution zone 19 alone takes over the heat distribution and conduction between the Peltier element 1 and the walls 7 of the storage space 2.
Um zu verhindern, daß sich die Abfuhr der von einer Steuerelek¬ tronik 12 herrührenden Wärme nachteilig auf die Wirkung des bzw. der Peltierelemente auswirkt, kann der Rippenwär etauschkörper 9 des Peltierelementes von dem Rippenkühlkörper 13 für die Kühlung einer Steuerelektronik getrennt angeordnet sein, wobei zwischen Rippenwärmetauscher und dem Rippenkühlkörper wärmeisolierende Bereiche des Gehäuses angeordnet sind.In order to prevent the dissipation of the heat originating from control electronics 12 adversely affecting the action of the Peltier element (s), the rib heat exchange body 9 of the Peltier element can be arranged separately from the fin cooling body 13 for cooling control electronics, heat-insulating regions of the housing being arranged between the fin heat exchanger and the fin cooling body.

Mit 1 ist ein Peltierelement bezeichnet, an dessen einer Seite, welche einem Aufbewahrungsraum 2 zugewandt ist, eine Wärmever¬ teilplatte 18 angeordnet ist. An dieser Wärmeverteilplatte sind rohrartige Wärmeleitkörper 3 angeordnet, welche vorliegend durch Aluminiumformrohre mit quadratischem Querschnitt gebildet sind. Die dem Aufbewahrungsraum 2 zugewandten Wandungen der Wärmeleit¬ körper 3 bilden gleichzeitig die Innenwandung des Aufbewahrungs¬ raumes 2. Die Wärmeleitkörper 3 können mittels Schrauben, Blind¬ nieten oder dergleichen wie dies in Fig. 4 bei 4 angedeutet ist, verbunden sein. Die Wärmeleitkörper 3 sind.mittels Klemmschienen 5 mit dem Peltierelement 1 verspannt, und zwar durch Schrauben 6. An den äußersten Wärmeleitkörpern 3 sind die Wandungen 7 des Aufbewahrungsraumes 2 befestigt, und zwar gleichfalls mittels Schrauben, Blindnieten oder dergleichen, welche mit 8 bezeichnet sind. Die Wandungen des Aufbewahrungsraumes sind gleichfalls aus gut wärmeleitendem Material gebildet.1 denotes a Peltier element, on one side of which faces a storage space 2, a heat distribution plate 18 is arranged. Pipe-like heat-conducting bodies 3 are arranged on this heat distribution plate, which in the present case are formed by shaped aluminum tubes with a square cross-section. The walls of the heat-conducting bodies 3 facing the storage space 2 simultaneously form the inner wall of the storage space 2. The heat-conducting bodies 3 can be connected by means of screws, blind rivets or the like as indicated at 4 in FIG. 4. The heat conducting bodies 3 are clamped to the Peltier element 1 by means of clamping rails 5, specifically by means of screws 6. The walls 7 of the storage space 2 are fastened to the outermost heat-conducting bodies 3, likewise by means of screws, blind rivets or the like, which are designated by 8. The walls of the storage space are also made of a good heat-conducting material.
Der dem Aufbewahrungsraum abgewandte Teil des Peltierele entes 1 steht mit einem Rippenwärmetauschkörper 9 in Verbindung, über welchen die aus dem Aufbewahrungsraum 2 abgeführte Wärme vom Pel¬ tierelement abgegeben wird. Wird das Peltierelelement zur Heizung benutzt, dann wird über den Rippenwärmetauschkörper 9 die für die Heizung benötigte Wärme aus der Umgebungsluft aufgenommen.The part of the Peltierele duck 1 facing away from the storage space is connected to a fin heat exchange body 9, via which the heat dissipated from the storage space 2 is released by the pelletizing element. If the Peltierel element is used for heating, then the heat required for the heating is absorbed from the ambient air via the fin heat exchange body 9.
Der Aufbewahrungsraum 2 befindet sich in einem Gehäuse 10 und ist von einer Wärmeisolierung 11 umgeben. In diesem Gehäuse 10 befin¬ det sich ferner eine Steuerelektronik 12, welche zur Abführung der dort auftretenden Wärme nahe einem Rippenkühlkörper 13 ange¬ ordnet ist. Der Rippenkühlkörper 13 der Steuerelektronik ist von dem Rippenwärmetauschkörper 9 des Peltierelementes räumlich ge¬ trennt angeordnet, wobei zwischen den beiden Körpern ein wärme¬ isolierender Bereich des Gehäuses angeordnet ist.The storage space 2 is located in a housing 10 and is surrounded by thermal insulation 11. In this housing 10 there is also control electronics 12 which is arranged near a fin cooling body 13 for dissipating the heat occurring there. The fin cooling body 13 of the control electronics is spatially separated from the fin heat exchange body 9 of the Peltier element, a heat-insulating area of the housing being arranged between the two bodies.
In dem Gehäuse 10 sind ferner noch ein Pufferakkumulator 14, ein Transformator 15, ein Netzschalter 16 und ein Bedienungsfeld 20 mit Ein- und Ausschaltaster zur In- oder Außerbetriebnahme der Temperierung des Aufbewahrungsraumes vorgesehen. Der eingebaute Pufferakkumulator 14 ist vorliegend als gasdichter Akkumulator ausgebildet, welcher einen lageunabhängigen, wartungsfreien Be¬ trieb ermöglicht. Die Regelung der Temperatur innerhalb des Auf¬ bewahrungsraumes 2 erfolgt über einen herkömmlichen Temperatur- fühler, welcher nahe den rohrartigen Wärmeleitkörpern 3, nahe dem einteiligen Wärmeleitformkörper 17 oder nahe dem einteiligen Formkörper mit integrierter Wärmeverteilzone 19 angeordnet ist und der mit der Steuerelektronik 12 verbunden ist.In the housing 10 there are also a buffer accumulator 14, a transformer 15, a power switch 16 and a control panel 20 with an on and off switch for putting the temperature of the storage space into or out of operation. In the present case, the built-in buffer accumulator 14 is designed as a gastight accumulator, which enables position-independent, maintenance-free operation. The regulation of the temperature within the storage space 2 takes place via a conventional temperature sensor which is arranged near the tubular heat-conducting bodies 3, near the one-piece heat-conducting molded body 17 or near the one-piece molded body with integrated heat distribution zone 19 and which is connected to the control electronics 12.
Die erfindungsgemäße Transport- und Aufbewahrungseinrichtung ist sehr einfach zu bedienen, da sie lediglich Einschaltetaster zur Inbetriebnahme der Temperierung des Aufbewahrungsraumes bzw. Ausschaltetaster zur Außerbetriebsetzung sowie einen Netzschalter aufweist. Die übrige Steuerung und bei externer Energiezuführung das Laden des eingebauten Pufferakkumulators erfolgen automa¬ tisch. The transport and storage device according to the invention is very easy to use, since it only has a switch-on button for starting the temperature control of the storage space or a switch-off button for decommissioning, as well as a power switch. The rest of the control and, in the case of external energy supply, the charging of the built-in buffer accumulator take place automatically.
