Abstract

The device has a heat exchanger through which heat supply fluid i.e. hot exhaust gas, flows, where the heat exchanger is provided with box-shaped heat supply- and heat transport-flow channels (1, 2) for the heat supply fluid and heat transport fluid, respectively. The heat transport-flow channel is provided with parallel round tubes. Linear opposite turbulator-strips (3) are attached on outer surfaces (9) of the heat supply-flow channel so that the heat supply-flow channel is linearly narrow at a position of opposite turbulator-pairs.

Description

Die Erfindung betrifft eine Vorrichtung zum Erwaermen eines Waermetransportfluides (Luft), bei der ein Waermelieferfluid (heisses Abgas) einen Waermetauscher mit getrennten Kanaelen fuer das Waermelieferfluid und das Waermetransportfluid durchstroemt und bei der die aeusseren Flaechen des kastenfoermigen Waermelieferkanales in erfindungsgemaesser Weise mit Turbulator-Streifen profiliert sind.The invention relates to a device for heating a heat transfer fluid (air), in which a heat transfer fluid (hot exhaust) through a heat exchanger with separate channels for the heat transfer fluid and the heat transfer fluid and profiled in which the outer surfaces of the box-shaped Waermelieferkanales in accordance with the invention with turbulator strips are.

Als naechstliegender Stand der Technik zeigt die DE 41 40 953 A1 einen kastenfoermigen Waermeliefer-Stroemungsraum und als Waermetransport-Stroemungsraum mehrere parallele runde Rohre. Die aeusseren Flaechen dieses Waermeliefer-Stroemungsraumes sind nicht profiliert und also sind die fuer den Waermeuebergang notwendigen Turbulenzen nicht vorhanden und also ist der Waerme-Uebergang zwischen heissem Abgas und der Luft nicht optimal.As the closest prior art shows the DE 41 40 953 A1 a box-shaped heat delivery room and as a heat transfer flow room several parallel round pipes. The outer surfaces of this heat supply flow space are not profiled and therefore the turbulences necessary for the heat transfer are not present and so the heat transfer between hot exhaust gas and the air is not optimal.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zu schaffen, die turbulenzmaessig optimale Waermeuebergangseigenschaften hat, die das Waermelieferfluid (heisses Abgas) auch unter Volllastbedingungen optimal herunterkuehlt.The invention has for its object to provide a device which turbulence moderately optimal heat transfer properties, which cools the Waermelieferfluid (hot exhaust) optimally under full load conditions.

Diese Aufgabe wird erfindungsgemaess dadurch geloest, dass die aeusseren Flaechen des kastenfoermigen Waermelieferkanales 1 breitbandfoermige Turbulator-Streifen 3 aufweisen, die im Waermelieferkanal 1 jeweils paarmaessig gegenueberliegend angebracht sind. Der Waermelieferkanal 1 ist also bei jedem gegenstaendigen Paar von Turbulator-Streifen 3 wie durch eine Blende verengt. Die Turbulator-Streifen 3 sind auf die aeusseren Seiten 9 des Waermelieferkanales 1 rechtwinklig aufgeschweisst.This object is achieved according to the invention in that the outer surfaces of the box-shaped heat delivery duct 1 wide-band turbulator strips 3 have, in the heat delivery channel 1 each paarzessig opposite are appropriate. The heat delivery channel 1 So it's every pair of turbulator strips 3 as if narrowed by a shutter. The turbulator strips 3 are on the outside pages 9 of the heat delivery channel 1 welded at right angles.

Innerhalb des kastenfoermigen Abgas-Waermeliefer-Stroemungsraumes 1 befinden sich mehrere parallel runde Rohre 2 die zusammen den zweiten Stroemungsraum 2 und zwar den Waermetransport-Stroemungsraum 2 darstellen. Der Waermetransport-Stroemungsraum 2 ist der Stroemungsraum fuer die Luft.Inside the boxy exhaust-gas delivery room 1 There are several parallel round tubes 2 which together the second flow room 2 namely the heat transfer flow room 2 represent. The heat transport flow room 2 is the flow room for the air.

Durch die Turbulator-Streifen 3 an den aeusseren Flaechen des Waerme-Lieferkanales 1 wird die Turbulenz des heissen Abgases optimiert. An der blendenartigen Position ”X” wird der Massenstrom des Abgases komprimiert und gleich nach dieser Position ”X” expandiert das Abgas in den Abschnitt ”Y” des Waermelieferkanales 1.Through the turbulator strips 3 on the outer surface of the heat supply channel 1 the turbulence of the hot exhaust gas is optimized. At the diaphragm-like position "X", the mass flow of the exhaust gas is compressed and immediately after this position "X", the exhaust gas expands into the section "Y" of the heat delivery duct 1 ,

Diese Expansion erzeugt starke Turbulenzen und somit stossen die heissen Abgasteilchen vermehrt an die Waermeuebergangsflaeche 14 zwischen dem Waermelieferkanal 1 und dem Rohrstroemungsraum 2. Durch Kompression und Expansion des Abgases und die dabei erzeugten Turbulenzen wird also der Waermeuebergang an der Flaeche 14 vom heissen Abgas an die Luft optimiert.This expansion creates strong turbulence and thus the hot exhaust particles increasingly hit the heat transfer surface 14 between the heat delivery channel 1 and the pipe flow room 2 , By compression and expansion of the exhaust gas and the turbulence generated thereby is the heat transfer on the surface 14 optimized from the hot exhaust to the air.

Die Erfindung ist in den Zeichnungen 1 bis 4 beispielhaft veranschaulicht und wird im Nachfolgenden anhand der Zeichnungen im Einzelnen erlaeutert.The invention is in the drawings 1 to 4 exemplified and will be explained below with reference to the drawings in detail.
