Abstract

The cooling system has the heat-sinking end (5) of one or more Peltier-effect elements (6) located at the condensation end (4) of a heat pipe (1). The heat pipe passes through the sheath of the container (3) and its vaporising end (7) is in contact with the inside of the container. A heat exchanger (9) is connected to the heat-releasing ends (8) of the Peltier-effect elements and provided with cooling fins. Thermally conducting metal sheets are connected to the vaporising end of the heat pipe. The inner wall of the container is connected to the vaporising end of the heat pipe.

Vorrichtung zum Kühlen von tragbaren IsolierbehälternDevice for cooling portable insulating containers

Die Erfindung betrifft eine Vorrichtung zum Kühlen von tragbaren Isolierbehältern unter Verwendung eines oder mehrerer Pe 11iere1emente.The invention relates to an apparatus for cooling of portable insulated containers using one or more 11iere1emente Pe.

Vorrichtungen dieser Gattung sind bekannt. So gehören z. B. Kühltaschen oder Kleinkühlboxen mit Pe 11iere 1ementen zum vorbekannten Stande der Technik (DE-OS 1 501 124). Hierbei sind die der Kühlung dienenden Pe 1tiere Iemente in direktem Kontakt mit dem Innenraum des Isolierbehälters. Diese Vorrichtungen haben den Nachteil, daß an der Wärme abgebenden Seit« der Pe 11iere 1emente die Wärme nur schlecht abgeführt werden kann. Bei Abschalten de'- Pel t i erel emente wandert sofort die Wärme von der Warmseite zur Kaltseite der Peltierelemente und teilt sich somit auch dem Inneren des Isolierbehälters mit. Darüber hinaus wird im abgeschalteten Zustand die Umgebungswärme ständig über die Peltierelemente In den zu kühlenden Behälter transportiert, da jene im abgeschalteten Zustand hervorragende Wärmeleiter sind.Devices of this type are known. So belong z. B. cool bags or small cool boxes with Pe 11iere 1ementen to the prior art (DE-OS 1 501 124). Here , the cooling elements are in direct contact with the interior of the insulated container. These devices have the disadvantage that the heat can only be dissipated poorly on the heat-emitting side of the pe 11ier elements. When the Peltier elements are switched off, the heat immediately migrates from the warm side to the cold side of the Peltier elements and is thus also communicated to the inside of the insulating container. In addition, when switched off, the ambient heat is constantly on the pel t ierelemente In the container to be cooled transported because those outstanding in the off state heat conductors.

Ausgehend von diesem vorbekannten Stande der Technik liegt der Erfindung die Aufgabe zugrunde,eIne Vorrichtung zum Kühlen von tragbaren Isolierbehältern unter Verwendung von Pe 11ierelementen zu schaffen, bei der ein Wärmetransport von außen in den Isolierbehälter bei abgeschalteten Peltlerelementen vermieden wird. On the basis of this known prior art, the invention is based on the object of creating a device for cooling portable insulating containers using PE elements, in which heat transfer from the outside into the insulating container is avoided when the Peltler elements are switched off.

Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale des Anspruchs 1 und der sich hieran anschließenden Unteransprüche 2 bis 5.This task is solved by the characteristic features of claim 1 and the subsequent subclaims 2 to 5.

HIerdurch wird erreicht, daß nach Abschalten der Peltlerelemente keinerlei Wärmetransport in den Isolierbehälter möglich ist, da das Wärmerohr hervorragende Wärmeisolier— eigenschaften besitzt. Die nach dem Abschalten der Peltierelemente von der Warmsette zur Kaltseite der Elemente fließende Wärme wird über das Wärmerohr nicht In den Innenraum des Isolierbehälters transportiert. Ein weiterer Vorteil besteht darin, daß dem Inhalt des Isolierbehälters die Wärme sehr schnell entzogen wird, da durch das Wärmerohr eine sehr große Oberfläche zur Verfugung steht, über die die Wärme aus dem Behä1terinneren abgeführt wird. Dieser Vorgang wird noch dadurch beschleunigt, da das Wärmerohr ein außerordentlich schneller Wärmetransporteur Ist, der es ermöglicht, die Wärme an einer großen Fläche aufzunehmen und über eine sehr kleine Fläche konzentriert abzugeben. Darüber hinaus ist es besonders vorteilhaft, daß die erfindungsgemäße Vorrichtung als Einheit austauschbar ist.This ensures that after the Peltler elements have been switched off no heat transfer to the insulated container is possible because the heat pipe has excellent thermal insulation properties. The after switching off the Peltier elements Heat flowing from the warm bed to the cold side of the elements is not transferred to the interior via the heat pipe of the insulating container transported. Another advantage is that the contents of the insulating container Heat is withdrawn very quickly, because the heat pipe has a very large surface available over which the heat is dissipated from the inside of the container. This Process is accelerated by the fact that the heat pipe it is an extraordinarily fast heat transporter enables the heat to be absorbed over a large area and released in a concentrated manner over a very small area. In addition, it is particularly advantageous that the inventive Device is interchangeable as a unit.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im folgenden näher beschrieben. Es ze i gen:An embodiment of the invention is in the drawings and is described in more detail below. Show it:

Die Vorrichtung besteht aus einem mit einer Siedeflüssigkeit teilweise gefüllten Wärmerohr 1, das im Deckel 2 eines Isolierbehälters 3 lösbar gehaltert ist. Die Kondensationsseite 4 des Wärmerohres 1 steht mit der Wärme aufnehmenden Seite 5 eines Peltierelementes 6 und die Verdampferseite mit dem Inneren des Isolierbehälters 3 In Verbindung.

The condensation side 4 of the heat pipe 1 is with the heat absorbing Side 5 of a Peltier element 6 and the evaporator side with the interior of the insulating container 3 in connection.

Kühlfahnen 10 versehener Wärmetauscher 9 angeordnet. In eingeschaltetem Zustand wird dem Inhalt des I sol Ierbehälters 3 Wärme über das Wärmerohr 1 und das Peltiere 1ement 6 entzogen. Dies wird dadurch erreicht, daß das Arbeitsmedium im Wärmerohr 1 verdampft und die Wärmeenergie im Dampf zur Kondensationsseite h transportiert wird. Der Dampf kondensiert hier und gibt dabei seine Wärme ab. Dieser Vorgang wird dadurch beschleunigt, daß die Kondensationsseite *4 des Wärmerohres 1 mit einem Peltierelement 6 verbunden Ist. Das Kondensat fließt von der Kondensationsseite 4 zurück zur Verdampferseite 7·Heat exchanger 9 provided with cooling tabs 10 is arranged. When switched on, heat is withdrawn from the contents of the I sol Ierbehälters 3 via the heat pipe 1 and the Peltiere element 6. This is achieved in that the working medium evaporates in the heat pipe 1 and the thermal energy is transported in the steam to the condensation side h . The steam condenses here and gives off its heat. This process is accelerated by the fact that the condensation side * 4 of the heat pipe 1 is connected to a Peltier element 6. The condensate flows from the condensation side 4 back to the evaporator side 7
