Abstract
Kryogener Wärmetauscher (5) mit einem Eingang (6) für flüssigen Stickstoff (LN2) sowie einem Ausgang (7) für den gasförmigen Stickstoff (N2), wobei der Wärmetauscher (5) als hohler Zylinder mit einem Zylindermantel (8), mit zwei zueinander parallelen Stirnseiten (9) sowie mit einem Labyrinth in seinem Inneren ausgebildet ist.Cryogenic heat exchanger (5) having a liquid nitrogen inlet (6) (LN 2 ) and an outlet (7) for the gaseous nitrogen (N 2 ), the heat exchanger (5) being a hollow cylinder with a cylinder jacket (8), with two mutually parallel end faces (9) and formed with a labyrinth in its interior.
Description
Die Erfindung betrifft einen gattungsgemässen, kryogenen Wärmetauscher.The The invention relates to a generic, cryogenic heat exchanger.
Es gibt verschiedene Sorten von Wärmetauscher, die stabile Temperaturen ermöglichen. Dabei wird in der Regel ein gut wärmeleitfähiges Material, z. B. Metall in den flüssigen Stickstoff getaucht und mit einem Heizelement an einer bestimmten Stelle durch Gegenheizen auf die gewünschte Temperatur gebracht sowie auf dieser Temperatur gehalten. Hierbei ergeben sich grössere Verluste an Stickstoff durch das Gegenheizen, was zu einem schlechten Wirkungsgrad führt und daher unerwünscht ist.It are different types of heat exchangers, which allow stable temperatures. In this case, a good heat conductive material, for. Metal in the liquid Dipped in nitrogen and with a heating element on a specific Place by counter heating to the desired temperature and kept at this temperature. This results in greater losses to nitrogen by the counter-heating, resulting in a poor efficiency leads and therefore undesirable is.
Der Erfindung liegt daher die Aufgabe zu Grunde einen gattungsgemässen Wärmetauscher mit besserem Wirkungsgrad vozuschlagen.Of the Invention is therefore the object of a generic heat exchanger with better efficiency.
Diese Aufgabe wird erfindungsgemäss durch den Gegenstand des Hauptanspruchs gelöst.These Task is according to the invention solved by the subject of the main claim.
Erfindungsgemäss ist der Wärmetauscher mit dem Lagyrinth auf relativ einfache Weise mit relativ geringem Maschinenaufwand in diversen Größen und Abmessungen, z. T: auch mit Standard- bzw. Normbauteilen einfach und kostengünstig herzustellen. Die Nachteile bekannter Wärmetauscher beim Stand der Technik werden durch die Erfindung vermieden, die genau geregelte Temperaturen ohne Gegenheizung im vorgenannten kryogenen Bereich ermöglicht. Mit dem erfindungsgemässen kryogenen Wärmetauscher können also mittels des flüssigen Stickstoffs Temperaturen im Bereich zwischen –190°C und +20°C mit relativ schnellen Abkühl- und Aufwärmraten in überraschend einfacher Weise sehr stabil gehalten werden; ausserdem kann er zum Beispiel an andere Geräte, in denen Proben auf einer bestimmten Temperatur sehr genau gehalten werden sollen, angeschlossen werden.According to the invention is the Heat exchanger with the Lagyrinth in a relatively simple manner with relatively little machinery in various sizes and Dimensions, z. T: easy even with standard or standard components and cost-effective manufacture. The disadvantages of known heat exchangers in the state of Technology is avoided by the invention, which is precisely controlled Temperatures without counterheating in the aforementioned cryogenic range allows. With the inventive cryogenic heat exchanger can So by means of liquid nitrogen Temperatures between -190 ° C and + 20 ° C with relatively fast cooling and warming rates in surprising easy to be kept very stable; He can also go to Example to other devices, in which samples are kept very accurately at a certain temperature be connected.
Zweckmässigerweise ist das Labyrinth von zumindest zwei, zu dem Zylindermantel konzentrische Hohlzylinder unter Bildung von Innenkammern ausgebildet, deren beide Stirnenden in zueinander konzentrischen, dem Inneren des Zylinders zugewandten Nuten der zwei zueinander parallelen Stirnseiten eingesetzt sind, wobei jeder Hohlzylinder mit zumindest einem radialen Durchlass versehen ist.Conveniently, is the labyrinth of at least two, concentric to the cylinder shell Hollow cylinder formed to form inner chambers, both of which Front ends in concentric with each other, the inside of the cylinder facing grooves of the two mutually parallel end faces used are, each hollow cylinder with at least one radial passage is provided.
Besonders lange Wege werden im Labyrinth von dem flüssigen bzw. kalten gasförmigen Stickstoff zurückgelegt, wenn jeder Hohlzylinder mit zwei oder mehr radialen Durchlässen versehen ist, deren Mittelpunkte auf einer parallel zu der Achse des Zylinders verlaufenden Gerade angeordnet sind, und der zumindest eine radiale Durchlass des einen Hohlzylinders diametral zu dem zumindest einen radialen Durchlass des dazu benachbart angeordneten anderen Hohlzylinders angeordnet ist.Especially long paths are covered in the labyrinth by the liquid or cold gaseous nitrogen, when each hollow cylinder is provided with two or more radial passages whose centers are on a plane parallel to the axis of the cylinder extending straight line are arranged, and the at least one radial Passage of a hollow cylinder diametrically to the at least one radial passage of adjacent thereto arranged another hollow cylinder is arranged.
Die Steuerung des erfindungsgemässen Wärmetauschers gestaltet sich dabei besonders einfach und erfolgt ohne Gegenheizen durch ein in Strömungsrichtung vor dem Eingang vorgesehenes, über die Menge des flüssigen Stickstoffs die Temperatur des Wärmetausches steuerndes Ventil.The Control of the heat exchanger according to the invention It is particularly easy and takes place without counter heating through a flow direction in front of the entrance, over the Amount of liquid Nitrogen the temperature of the heat exchange controlling valve.
