Abstract
Description
Die Erfindung betrifft eine Kühlvorrichtung zur Kontaktkühlung
gemäß dem Oberbegriff des Anspruchs 1,
vorzugsweise von
Getränkebehältern und anderen durch Wärmeentzug abzukühlenden Objekten,
umfassend ein Kühlelement oder mehrere miteinander verbundene Kühlelemente,
wobei jedes Kühlelement mindestens eine flexible Kontaktwandung, die geeignet
ist für den Wärmeübergang zu einem Kühlobjekt, und eine Außenwandung mit
einer Wärmeisolierung, die mindestens eine Kammer mit einer Füllung eines
fließfähigen Kühlmittels bilden, aufweist, wie durch die US-A-3736769 bekanntgeworden.The invention relates to a cooling device for contact cooling
according to the preamble of
Derartige Kühlvorrichtungen sind in verschiedenen Bauformen seit langem bekannt. Sie sind in der Regel aus zwei flexiblen Kunststofffolien geschweißt und mit einem sogenannten Kältegel gefüllt, das je nach Kältemischung auf sehr tiefe Temperaturen, z.B. -20 bis -30°C, abgekühlt werden kann und dabei noch fließfähig und beweglich bleibt. Auch die verwendeten Folien sind für diese Temperaturen geeignet.Such cooling devices have long been known in various designs. They are usually welded from two flexible plastic films and with a so-called cold gel filled, which depending on the cold mixture to very deep Temperatures, e.g. -20 to -30 ° C, can be cooled and still flowable and remains flexible. The foils used are also for these temperatures suitable.
Diese flexiblen Kühlvorrichtungen sind in der Lage, sich formmäßig gut an die abzukühlenden Objekte anzupassen und dadurch einen guten Wärmeübergang zu erzeugen. Ihr großer Nachteil ist die sehr kleine spezifische Kühlkapazität, da sie nur fühlbare Wärme speichern können, z.B. ca. 3800 J/kg ·K.These flexible cooling devices are able to conform well to those to be cooled Adapt objects and thereby a good heat transfer produce. Their big disadvantage is the very small specific cooling capacity as they can only store sensible heat, e.g. approx. 3800 J / kgK.
Es sind auch andere Kühlvorrichtungen, sogenannte Kühlakkus bekannt, die mit Kühlsole arbeiten. Diese Kühlsole gefriert bei einem definierten Temperaturpunkt und gibt dabei sehr viel latente Wärme ab, die sie in diesem Temperaturpunkt beim Schmelzen wieder aufnimmt. Diese Latentwärme beträgt ca. 295 000 bis J/kg z.B. bei -12°C.There are also known other cooling devices, so-called cold packs, which Cooling brine work. This cooling brine freezes at a defined temperature point and gives off a lot of latent heat that they have at this temperature point resumes when melting. This latent heat is approximately 295,000 to J / kg e.g. at -12 ° C.
Der große Nachteil der Kühlakkus ist deren absolute Steifigkeit im eingefrorenen Zustand, oft noch verbunden mit Deformationen durch die undefinierte Form des Solebehälters und Deformationen beim und durch das Gefrieren. Diese Akkus liegen bei Kühlungsbeginn am Kühlobjekt nur punktförmig an, was einen schlechten Wärmeübergang, damit lange Kühlzeiten und entsprechend höhere Kältekapazitätsverluste durch Wärmeaufnahme aus der Umgebung bedeutet. Diese Verluste können zwar durch eine zusätzliche außenliegende Wärmeisolierung reduziert werden, relativ steigen sie trotzdem mit der Kühlzeit.The big disadvantage of cold packs is their absolute rigidity when frozen Condition, often combined with deformations due to the undefined shape of the Brine tank and deformations during and through freezing. These batteries are lying at the beginning of cooling on the cooling object only at points, which is a bad thing Heat transfer, therefore long cooling times and correspondingly higher cooling capacity losses by absorbing heat from the environment. These losses can be reduced by additional external heat insulation relative, they nevertheless increase with the cooling time.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Kühlvorrichtung zur Kontaktkühlung der eingangs genannten Art ohne die Nachteile der bekannten Kühlvorrichtungen zu schaffen, die zudem auch von ungeübten Benutzern leicht und sicher zu handhaben ist und bei kostengünstiger Herstellung ein ansprechendes Aussehen besitzt.The invention is therefore based on the object of a cooling device for contact cooling of the type mentioned without the disadvantages of the known cooling devices to create that also easy and inexperienced users is safe to use and an attractive one with inexpensive production Looks.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass zwischen wärmeisolierter Außenwandung und flexibler Kontaktwandung zumindest eine mit einer Kältesole gefüllte Kapsel angeordnet ist. Damit liegen eine hohe Kühlkapazität, kurze Kühlzeiten und geringe Wärmeverluste vor.This object is achieved in that between heat-insulated Outer wall and flexible contact wall at least one with one Cold brine filled capsule is arranged. So there is a high cooling capacity, short cooling times and low heat losses.
Die erfindungsgemäße Kühlvorrichtung kombiniert in hervorragender Weise die Vorteile der bekannten Kühlvorrichtungen, nämlich einerseits den guten Wärmeübergang zum Kühlobjekt durch flexible Formanpassung der Kontaktwandung und andererseits die große Kältekapazität in einem definierten Latentwärme-Temperaturpunkt, z.B. -12°C, zum schnellen Abkühlen, z.B. von gefüllten Getränkebehältern, auf Temperaturen zwischen +2°C bis +12°C. Dabei wird der gute Wärmeübergang nicht nur von glattwandigen, sondern auch von regelmäßig oder unregelmäßig geformten Oberflächen durch die flexible Formanpassung ermöglicht. Die im fließfähigen Kühlmittel eingebetteten Kältesole-Kapseln geben ihre Kühlkapazität infolge guter Wärmeleitung im Kühlmittel, z.B. Kältegel, über dieses an das Kühlobjekt ab. Dabei gibt auch das Kühlmittel seine relativ geringe eigene . Kühlkapazität ab.The cooling device according to the invention combines the in an excellent manner Advantages of the known cooling devices, namely the good heat transfer on the one hand to the cooling object through flexible adaptation of the shape of the contact wall and on the other hand the large cooling capacity in a defined latent heat temperature point, e.g. -12 ° C, for quick cooling, e.g. of filled beverage containers, to temperatures between + 2 ° C to + 12 ° C. The good one Heat transfer not only from smooth-walled, but also from regular or irregularly shaped surfaces thanks to the flexible shape adjustment. The brine capsules embedded in the flowable coolant give theirs Cooling capacity due to good heat conduction in the coolant, e.g. Cold gel, about this to the cooling object. The coolant also has its own relatively low level , Cooling capacity.
Die volumenbezogene Mengenverteilung von Kühlmittel zu Kältesole ist stark abhängig vom Kühlobjekt und dem Aufbau und der Formgebung der Kühlelemente. In der Regel liegt das Massenverhältnis von Kühlmittel zu Kältesole in der Größenordnung von 1:3 bis 1:5. Messungen an erfindungsgemäßen Kühlvorrichtungen haben beim Abkühlen von z. B. Getränkebehältern von Raumtemperatur auf Trinktemperatur, z.B. 8°C, eine Verkürzung der Abkühlzeit um ca. 40-50% gegenüber Kälteakkus bei einer Reduzierung der erforderlichen Kühlmittel-Gesamtmasse ergeben. Dadurch und durch die Verwendung der preiswerteren Kältesole im Vergleich zum Kühlgel ist die Kühlvorrichtung insgesamt kostengünstiger und werden die Wartezeit bis zum Verzehrbeginn der Getränke bei gewünschter Temperatur und die "Kälteverluste" nach außen deutlich kürzer bzw. verringert. Das Gesamtgewicht und -volumen ist gegenüber reinen Gel-Kühlern um 60-70% erheblich reduziert, was weitere Vorteile beim erneuten Einfrieren (Aufladen) der Kühlvorrichtung im Gefriergerät bedeutet.The volume-related quantity distribution from coolant to cooling brine is heavily dependent of the cooling object and the structure and shape of the cooling elements. As a rule, the mass ratio of coolant to brine is of the order of magnitude from 1: 3 to 1: 5. Measurements on cooling devices according to the invention have when cooling z. B. Beverage containers from room temperature Drinking temperature, e.g. 8 ° C, compared to a shortening of the cooling time by approx. 40-50% Cold accumulators with a reduction in the total coolant mass required result. As a result, and by using the cheaper Cooling brine compared to cooling gel, the cooling device is generally less expensive and the waiting time until the start of consumption of the drinks at the desired Temperature and the "cold losses" to the outside are significantly shorter or reduced. The total weight and volume is compared to pure gel coolers significantly reduced by 60-70%, which has further advantages when re-freezing (Charging) the cooling device in the freezer means.
