Definitions
- the invention relates to a turbulator insert for heat exchangers with tubular heat transfer surfaces, comprising a wound around the longitudinal axis of the Wirbelberein tenues body.
- Wirbulatorein accounts of the type mentioned are for example from the DE 29 707 325 U1 known.
- Such inserts are wound in the longitudinal direction of the vortex insert body, preferably bleaching strips. These inserts serve to interrupt the substantially laminar flow of a carrier medium, which is, for example, liquid or gaseous, within the tubular heat transfer surfaces and thereby to lead to the wall of the tubular heat transfer surfaces in order to intensify the heat transfer.
- a carrier medium which is, for example, liquid or gaseous
- tubular heat transfer surfaces In the course of maintenance, the tubular heat transfer surfaces must be inspected and cleaned, whereby the Vorbulereinein algorithms must be removed. Especially with elongated, vertically arranged tubular heat transfer surfaces and limited space at the site of the tubular heat transfer surfaces make this work extremely difficult.

- the annular element is configured, for example, like a snap hook.
- the annular element is designed as a round chain link.
- connection between the at least two parts of the body is formed so that the two are movable by at least 90 ° relative to each other, preferably up to 180 °. This ensures that the turbulator insert can be used or removed in tubular heat transfer surfaces, as long as the length of the individual parts of the body are smaller than the available space for installation or removal.

Die
Aufgabe der Erfindung ist es, Wirbulatoreinsätze bereitzustellen, welche auch bei beengten Raumverhältnissen einfach in Wärmedurchgangsflächen eingebracht bzw. aus den rohrförmigen Wärmedurchgangsflächen entfernt werden können.The object of the invention is to provide Wirbulatoreinsätze, which can be easily introduced even in confined spaces in heat transfer surfaces or removed from the tubular heat transfer surfaces.
Gelöst wird die Aufgabe durch einen Wirbulatoreinsatz für Wärmetauscher mit rohrförmigen Wärmedurchgangsflächen, umfassend einen um die Längsachse des Wirbulatoreinsatzes gewundenen Körper, wobei der Körper aus mindestens zwei Teilen besteht, welche relativ zueinander beweglich verbindbar ausgestaltet sind. Dadurch, dass die wenigstens zwei Teile des Körpers relativ zueinander beweglich verbunden sind, kann die Gesamtlänge des gewundenen Körpers durch eine Relativbewegung zwischen den mindestens zwei Teilen des Körpers verringert werden, wodurch der Einbau bzw. Ausbau eines solchen Wirbulatoreinsatzes in rohrförmigen Wärmedurchgangsflächen deutlich vereinfacht wird.The object is achieved by a vortex use for heat exchangers with tubular heat transfer surfaces, comprising a wound around the longitudinal axis of the Vorbulatoreinsatzes body, wherein the body consists of at least two parts which are designed to be movable relative to each other connectable. Characterized in that the at least two parts of the body are movably connected relative to each other, the total length of the tortuous body can be reduced by a relative movement between the at least two parts of the body, whereby the installation or expansion of such a Vortexulator insert is significantly simplified in tubular heat transfer surfaces.
Nach dem Einbau des erfindungsgemäßen Wirbulatoreinsatzes in eine rohrförmige Wärmedurchgangsfläche werden die wenigstens zwei Teile des gewundenen Körpers relativ zueinander durch die radiale Begrenzung der rohrförmigen Wärmedurchgangsfläche fixiert, sodass sich ein in der Länge starrer Wirbulatoreinsatz ergibt.After installation of the turbulator insert according to the invention in a tubular heat transfer surface, the at least two parts of the tortuous body are fixed relative to each other by the radial boundary of the tubular heat transfer surface, so that results in a rigid vortex in the insert.
Durch eine Anpassung der Länge der einzelnen Teile des gewundenen Körpers können Wirbulatoreinsätze bereitgestellt werden, die auch bei äußerst begrenzten Platzverhältnissen eingesetzt werden können.By adjusting the length of the individual parts of the tortuous body, it is possible to provide turbulator inserts which can also be used in extremely limited space.
Nach einer Variante der Erfindung ist die Verbindung zwischen den wenigstens zwei Teilen des Körpers lösbar ausgestaltet. Dadurch, dass die Verbindung zwischen den wenigstens zwei Teilen des Körpers lösbar ist, können einzelne Teile des Wirbulatoreinsatzes auf einfache Art und Weise ausgetauscht werden. Eine solche lösbare Verbindung zwischen den wenigstens zwei Teilen des gewundenen Körpers umfasst beispielsweise eine Schraubverbindung, eine Rastverbindung oder eine Bolzenverbindung.According to a variant of the invention, the connection between the at least two parts of the body is made detachable. Characterized in that the connection between the at least two parts of the body is solvable, individual parts of the Wirbulatoreinsatzes can be exchanged in a simple manner. Such a detachable connection between the at least two parts of wound body includes, for example, a screw, a snap connection or a bolt connection.
Nach einer alternativen Variante der Erfindung ist die Verbindung zwischen den wenigstens zwei Teilen des Körpers nicht lösbar ausgestaltet, beispielsweise mittels einer Nietverbindung.According to an alternative variant of the invention, the connection between the at least two parts of the body is designed not detachable, for example by means of a riveted joint.
Nach einer weiteren Variante der Erfindung ist die Verbindung zwischen den wenigstens zwei Teilen des gewundenen Körpers durch ein ringförmiges Element ausgebildet. Im Falle einer lösbaren Verbindung ist das ringförmige Element beispielsweise wie ein Karabinerhaken ausgestaltet. Bei einer nicht lösbaren Verbindung ist das ringförmige Element als Rundkettenglied ausgestaltet. Eine Verbindung mittels eines ringförmigen Elements hat den Vorteil, dass die Relativbewegung zwischen den wenigstens zwei Teilen des Körpers hinsichtlich eines Verschwenkungswinkels kaum eingeschränkt ist und gleichzeitig eine Relativbewegung zwischen den beiden Teilen des gewundenen Körpers in Längsrichtung nahezu vermieden wird.According to a further variant of the invention, the connection between the at least two parts of the tortuous body is formed by an annular element. In the case of a releasable connection, the annular element is configured, for example, like a snap hook. In a non-detachable connection, the annular element is designed as a round chain link. A connection by means of an annular element has the advantage that the relative movement between the at least two parts of the body with respect to a Verschwenkungswinkels is hardly limited and at the same time a relative movement between the two parts of the coiled body in the longitudinal direction is almost avoided.
Nach einer bevorzugten Variante der Erfindung ist die Verbindung zwischen den wenigstens zwei Teilen des Körpers so ausgebildet, dass die beiden um wenigstens 90° relativ zueinander bewegbar sind, vorzugsweise bis zu 180°. Dadurch ist gewährleistet, dass der Wirbulatoreinsatz in rohrförmige Wärmedurchgangsflächen eingesetzt bzw. ausgebaut werden kann, solange die Länge der einzelnen Teile des Körpers geringer sind als der zur Verfügung stehende Raum zum Ein- bzw. Ausbau.According to a preferred variant of the invention, the connection between the at least two parts of the body is formed so that the two are movable by at least 90 ° relative to each other, preferably up to 180 °. This ensures that the turbulator insert can be used or removed in tubular heat transfer surfaces, as long as the length of the individual parts of the body are smaller than the available space for installation or removal.
Nach einer zweckmäßigen Variante der Erfindung besteht der Körper aus Metall oder einem glasartigen Werkstoff, insbesondere aus Materialien, die nach dem Gussverfahren, z. B. Spritzguss, weiterverarbeitbar sind.According to an expedient variant of the invention, the body consists of metal or a glassy material, in particular of materials which are produced by the casting process, for. As injection molding, are processed.
Gemäß einer Variante der Erfindung sind die wenigstens zwei Teile des Körpers streifenförmig ausgebildet. Die streifenförmige Teile haben dabei eine Breite, die ungefähr dem Innendurchmesser der rohrförmigen Wärmedurchgangsflächen entspricht, sodass die streifenförmigen Teile vorzugsweise möglichst passgenau in die rohrförmigen Wärmedurchgangsflächen des Wärmetauschers einsetzbar sind. Dadurch wird erreicht, dass möglichst viel der Wärmeströmung in den rohrförmigen Wärmedurchgangsflächen mittels der streifenförmige Teile an die Wandung der rohrförmigen Wärmedurchgangsflächen zuführen.According to a variant of the invention, the at least two parts of the body are strip-shaped. The strip-shaped parts have a width which corresponds approximately to the inner diameter of the tubular heat transfer surfaces, so that the strip-shaped parts preferably as accurately as possible can be used in the tubular heat transfer surfaces of the heat exchanger. It is thereby achieved that as much as possible of the heat flow in the tubular heat transfer surfaces by means of the strip-like parts to the wall of the tubular heat transfer surfaces.
In einer weiteren bevorzugten Variante der Erfindung ist die Verbindung zwischen den wenigstens zwei Teilen des Körpers derart ausgebildet, dass die Verbindung durch die Relativbewegung der Teile zueinander nicht gelöst wird. Dies vereinfacht den Ein- bzw. Ausbau des Wirbulatoreinsatzes in die rohrförmigen Wärmedurchgangsflächen des Wärmetauschers, da die Verbindung zwischen den wenigstens zwei Teilen des Körpers während der Relativbewegung zwischen den wenigstens zwei Teilen nicht gelöst wird.In a further preferred variant of the invention, the connection between the at least two parts of the body is formed such that the connection is not solved by the relative movement of the parts to each other. This simplifies the installation or removal of the turbulator insert in the tubular heat transfer surfaces of the heat exchanger, since the connection between the at least two parts of the body during the relative movement between the at least two parts is not solved.
