Description
Rohrförmiger Wärmeaustauscher mit einer aus einem wellenförmigen Rohr gebildeten Trennwand Den Gegenstand der Erfindung bildet ein rohrförmiger Wärineaustauscher, bei dem das Wärme abgebende Mittel durch den schraubenförinigen Raum zwischen einem wellenförmigen Rohr und einem dieses dicht umschließenden zylindrischen Mantelrohr geleitet wird, während das Wärme aufnehmende Kühlmittel an der Innenseite des wellenförinigen Rohres geführt wird, innerhalb dessen ein weiteres zylindrisches Innenrohr zum Einführen des Kühlmittels vorgesehen ist. Derartige Wärmeaustauscher sind bekannt.Tubular heat exchanger with one made of a corrugated tube formed partition wall The object of the invention forms a tubular heat exchanger, in which the heat releasing agent through the helical space between one wave-shaped tube and a cylindrical jacket tube that tightly encloses this is conducted, while the heat-absorbing coolant on the inside of the wave-shaped Tube is guided, within which a further cylindrical inner tube for insertion of the coolant is provided. Such heat exchangers are known.
Erfindungsgemäß sind bei einem derartigen rohrförinigen Wänneaustauscher sowohl das Kühlmittel als auch das zu kühlende Medium dem Wärineaustauscher an seinem einen Ende zuführbar, derart, daß das Kühlmittel zum Durchströmen durch das als Sammel- und/oder Ausscheidungsbehälter dienende Innenrohr gezwungen und nach dem Austritt aus demselben und Richtungswechsel im Gegenstrom zum wendelförinig strömenden zu kühlenden Medium ebenso wie dieses wendelförinig entlang des gesamten gewellten Rohres bis zu seinem in den vom abgeschlossenen Innenrohrende und der Stimwand des Wärineaustauschers abgegrenzten Raum einmündenden Ende geführt ist.According to the invention in such a tubular heat exchanger both the coolant and the medium to be cooled to the heat exchanger on his one end can be fed in such that the coolant can flow through the as Collection and / or excretion container serving inner tube forced and after Exit from the same and change direction in countercurrent to the helical flowing Medium to be cooled as well as this helical along the entire corrugated Tube up to its in the closed inner tube end and the front wall of the Heat exchanger delimited space leading end is performed.
Nach dem Stand der Technik sind sowohl das Kühlmittel als auch das zu kühlende Medium wendelförmig im Gegenstrom bewegt, indessen findet kein Richtungswechsel des Kühlmittels statt. Aus diesem Grund können beim Anschluß des Wärmeaustauschers an ein Kälteaggregat die aus dem Verdampfer mitgerissenen Flüssigkeitsteilchen des Kältemittels nicht abgeschieden und teilweise verdampft werden. Auch findet kein beschleunigtes Hochwinden des Gases an der Innenseite des gewellten Rohres statt, zumal das Einführen des zu kühlenden Mediums im Gegensatz zur Erfindung von unten erfolgt, Durch den erfindungsgemäßen Richtungswechsel des Kältemittels werden die aus dem Verdampfer mitgerissenen Flüssigkeitsteilchen abgeschieden. Sie sammeln sich am Boden des Zylinders und können teilweise verdampfen.In the prior art, both the coolant and the The medium to be cooled moves helically in countercurrent, but there is no change of direction of the coolant instead. For this reason, when connecting the heat exchanger the liquid particles of the entrained from the evaporator to a refrigeration unit Refrigerant are not separated and partially evaporated. Also does not find any accelerated wind up of the gas on the inside of the corrugated pipe, especially since the introduction of the medium to be cooled, in contrast to the invention, from below takes place, by the change in direction of the refrigerant according to the invention, the Particles of liquid entrained from the evaporator are deposited. they collect at the bottom of the cylinder and can partially evaporate.
Gemäß einem weiteren Merkmal der Erfindung ist das mit dem Mantelrohr verbundene Wellrohr auch an seinen Täler bildenden Teilen durch einen Zwischenraum von dem Innenrohr getrennt. Auf dem Wege durch diesen Zwischenraum können die sich an der Innenseite des Wellrohres mit größerer Geschwindigkeit hochwindenden Flüssigkeitsteilchen weiterhin verdampft werden.According to a further feature of the invention, that is with the jacket pipe connected corrugated pipe also at its valleys forming parts through a gap separated from the inner tube. On the way through this interspace they can Liquid particles that wind up on the inside of the corrugated pipe at greater speed continue to be vaporized.
Bei der Verwendung eines Wärineaustauschers gemäß der Erfindung in einem Kälteaggregat zur Kühlung des vom Kondensator kommenden flüssigen Kältenüttels tritt eine Unterkühlung des flüssigen Kältemittels ein. Dadurch wird die Kälteleistung zurückgewonnen, die sonst für die Abkühlung der Flüssigkeit im Verdampfer benötigt wird. Ein solcher Wärineaustauscher ist in der Zeichnung schematisch, hauptsächlich im Längsschnitt, dargestellt.When using a heat exchanger according to the invention in a cooling unit for cooling the liquid cold shaker coming from the condenser subcooling of the liquid refrigerant occurs. This increases the cooling capacity recovered that would otherwise be needed to cool the liquid in the evaporator will. Such a heat exchanger is mainly schematic in the drawing shown in longitudinal section.
Das gasförinige vom Verdampfer kommende Kältemittel strömt von dem Eintrittsstutzen 1 aus über die Leitung 2 in das innere Rohr 3 und dann in umgekehrter Richtung durch den Zwischenraum zwischen dem Rohr 3 und dem wellenförinigen Rohr 4 durch den Raum 5 mit erweitertem Querschnitt zum Austrittsstutzen 6. Das zu kühlende flüssige Kältemittel strömt von dem Eintrittsstutzen 7 durch den wendelförmigen zwischen dem wellenförmigen Rohr 4 und dem Mantelrohr 8 gebildeten Raum zum Austrittsstutzen 9. Das wellenförmige Rohr 4 liegt dicht gegen die Innenseite des Mantelrohres 8 an, so daß die durchströmende Flüssigkeit im wesentlichen gezwungen ist, einen wendelfönnigen Weg einzuschlagen. Sie strömt dabei in dem der Strömung des gasförmigen wärineaufnehmenden Kältemittels zwischen den Rohren 3 und 4 entgegengesetzten Sinn.The gaseous refrigerant coming from the evaporator flows from the inlet connection 1 via the line 2 into the inner pipe 3 and then in the opposite direction through the space between the pipe 3 and the welleförinigen pipe 4 through the space 5 with an enlarged cross-section to the outlet connection 6 Liquid refrigerant to be cooled flows from the inlet connector 7 through the helical space formed between the corrugated tube 4 and the jacket tube 8 to the outlet connector 9. The corrugated tube 4 lies tightly against the inside of the jacket tube 8 so that the liquid flowing through is essentially forced to take a spiral path. It flows in the opposite direction to the flow of the gaseous heat-absorbing refrigerant between the tubes 3 and 4.
