In einigen Ausführungsformen stellt die vorliegende Erfindung einen Wärmetauscher, der einen Strömungsweg für ein erstes Arbeitsfluid und einen Strömungsweg für ein zweites Arbeitsfluid definiert, ein Rohr, das mindestens teilweise den ersten oder den zweiten Strömungsweg definiert, sowie einen gewellten Einsatz bereit, der am Rohr gesichert und entlang dem Strömungsweg des ersten Arbeitsfluids positioniert ist. In einigen Ausführungsformen ist an einer Stelle am Einsatz eine Sollbruchstelle vorgesehen, so dass ein Versagen an dieser Stelle auftritt.In some embodiments The present invention provides a heat exchanger that has a flow path for a first working fluid and a flow path for a second working fluid defines a tube that at least partially the first or the second flow path defined, as well as a corrugated insert, which is secured to the pipe and along the flow path the first working fluid is positioned. In some embodiments If a predetermined breaking point is provided at one point on the insert, so that a failure occurs at this point.
Die vorliegende Erfindung stellt auch einen Wärmetauscher mit einem Kopfteil und einem am Kopfteil gesicherten Rohr bereit. Ein gewellter Einsatz kann an einer Oberfläche des Rohrs gesichert sein und eine Nut beinhalten, die mindestens entlang einem Abschnitt einer Länge des Einsatzes ausgebildet und von der Oberfläche des Rohrs, an dem der Einsatz gesichert ist, beabstandet ist. In einigen Ausführungsformen kann der gewellte Einsatz zwischen zwei gegenüberliegenden Oberflächen des Rohrs gesichert und die Nut auf halbem Weg entlang einer Höhe des Einsatzes ausgebildet sein.The The present invention also provides a heat exchanger having a header and a tube secured to the headboard. A wavy insert can on a surface be secured to the tube and include a groove that at least along a section of a length formed of the insert and from the surface of the pipe to which the insert is secured, is spaced. In some embodiments, the corrugated Insert between two opposite surfaces secured to the pipe and the groove half way along a height of the insert be educated.
In einigen Ausführungsformen stellt die vorliegende Erfindung einen Wärmetauscher mit einem Rohr und einem durch das Rohr abgestützten Einsatz bereit. Der Einsatz kann eine gewellte Form mit einem Gipfel und einem angrenzenden Tal sowie eine Nut aufweisen, die entlang einer Längsabmessung des Einsatzes zwischen dem Gipfel und dem Tal so verläuft, dass ein Versagen der Konstruktion an einer bevorzugten Stelle zwischen dem Gipfel und dem Tal auftritt.In some embodiments the present invention provides a heat exchanger with a tube and one supported by the pipe Ready to use. The insert can be a wavy shape with a summit and an adjacent valley and a groove along a longitudinal dimension the insert between the summit and the valley runs so that a failure of the construction at a preferred location between the summit and the valley occurs.
Die vorliegende Erfindung stellt auch ein Verfahren zur Montage eines Wärmetauschers bereit, das das Bereitstellen eines Wärmetauscherrohrs und das Positionieren eines Einsatzes im Rohr beinhaltet. Das Verfahren kann auch die Schritte des Verbindens des Einsatzes mit einer Oberfläche des Rohrs und des Ausbildens einer Sollbruchstelle mindestens entlang einem Abschnitt einer Länge des Einsatzes in einer maximalen Distanz von einem Verbindungspunkt zwischen dem Einsatz und der Oberfläche des Rohrs beinhalten, so dass ein Versagen entlang der Sollbruchstelle auftritt.The The present invention also provides a method for assembling a heat exchanger ready to provide a heat exchanger tube and positioning an insert in the tube includes. The procedure can also be the Steps of connecting the insert to a surface of the Pipe and the formation of a predetermined breaking point at least along a section of a length use at a maximum distance from a connection point between the insert and the surface of the pipe, causing a failure along the predetermined breaking point occurs.
