DOLLAR A To create a heat exchanger, which has a higher heat output than conventional simply flowed through heat exchanger, the flat tubes (20) have a clear inner tube width of more than 1.2 mm and indentations (26-29), which are in the interior the flat tubes extend.
Description
Die Erfindung betrifft einen Wärmeübertrager, insbesondere einen Heizkörper, für eine Klimaanlage mit Flachrohren, die in einer Richtung von Kühlmittel durchströmt werden und zwischen denen Luftleiteinrichtungen angeordnet sind, die von Luft oder einem anderen Medium umströmt werden.The Invention relates to a heat exchanger, especially a radiator, for one Air conditioning with flat tubes, in a direction of coolant flows through and between which louvers are arranged, which are flowed around by air or another medium.

der deutschen Offenlegungsschrift
Aufgabe der Erfindung ist es, einen Wärmeübertrager, insbesondere einen Heizkörper, für eine Klimaanlage, gemäß dem Oberbegriff des Anspruchs 1 zu schaffen, der eine höhere Heizleistung aufweist als herkömmliche einfach durchströmte Wärmeübertrager, insbesondere Heizkörper.task the invention is a heat exchanger, especially a radiator, for an air conditioner, according to the generic term of claim 1, which has a higher heating power than conventional simply flowed through Heat exchanger, especially radiators.
Die Aufgabe ist bei einem Wärmeübertrager, insbesondere einem Heizkörper, für eine Klimaanlage mit Flachrohren, die in einer Richtung von Kühlmittel durchströmt werden und zwischen denen Luftleiteinrichtungen angeordnet sind, die von Luft oder einem anderen Medium umströmt werden, dadurch gelöst, dass die Flachrohre eine lichte innere Rohrweite von mehr als 1,2 mm und Einprägungen aufweisen, die sich in den Innenraum der Flachrohre erstrecken. Als lichte innere Rohrweite wird die Höhe des Innenraums eines Flachrohrs bezeichnet. Die vorliegende Erfindung schafft entgegen von üblichen Auslegungsregeln und Vorurteilen einen Kompromiss zwischen der Forderung nach einer hohen Heizleistung und dem Ziel, den kühlmittelseitigen Druckabfall möglich klein zu halten. Die relativ große lichte innere Rohrweite führt zu einem relativ kleinen Druckabfall auf der Kühlmittelseite, aber auch zu geringerer Heizleistung. Dieser Nachteil kann jedoch durch die partiellen Einprägungen, die auch als Winglets bezeichnet werden, behoben werden. Durch die Einprägungen wird der Wärmeübergang auf der Kühlmittelseite verbessert, wobei der kühlmittelseitige Druckabfall bei geeigneter Geometrie der Einprägungen nicht oder nur moderat ansteigt.The Task is with a heat exchanger, in particular a radiator, for one Air conditioning with flat tubes, in a direction of coolant flows through and between which louvers are arranged, which are flowed around by air or another medium, solved by that the flat tubes have a clear inner tube width of more than 1.2 mm and impressions have, which extend into the interior of the flat tubes. As a clear inner tube width is the height of the interior of a flat tube designated. The present invention provides contrary to usual design rules and prejudice a compromise between the demand for one high heat output and the target, the coolant side pressure drop possible to keep small. The relatively large clear inner tube width leads to a relatively small pressure drop on the coolant side, but also too lower heating power. However, this disadvantage can be due to the partial indentations, which are also referred to as winglets to be fixed. By the impressions becomes the heat transfer on the coolant side improved, wherein the coolant side Pressure drop with suitable geometry of the impressions not or only moderately increases.
Ein bevorzugtes Ausführungsbeispiel des Wärmeübertragers ist dadurch gekennzeichnet, dass die Einprägungen eine Tiefe von 0,1 bis 0,4 mm aufweisen. Diese Werte haben sich im Rahmen der vorliegenden Erfindung als besonders vorteilhaft erwiesen.One preferred embodiment of the heat exchanger is characterized in that the impressions have a depth of 0.1 to 0.4 mm. These values have changed in the context of the present Invention proved to be particularly advantageous.
Ein weiteres bevorzugtes Ausführungsbeispiel des Wärmeübertragers ist dadurch gekennzeichnet, dass die Flachrohre eine lichte innere Rohrweite von 1,3 bis 1,5 mm aufweisen. Vorzugsweise haben die Flachrohre eine lich te Rohrweite von 1,38 mm. Dabei sind übliche, herstellungsbedingte Toleranzen zu berücksichtigen.One Another preferred embodiment of the heat exchanger is characterized in that the flat tubes have a light inner Pipe width of 1.3 to 1.5 mm. Preferably, the flat tubes a lich th pipe width of 1.38 mm. These are usual, production-related To consider tolerances.
Ein weiteres bevorzugtes Ausführungsbeispiel des Wärmeübertragers ist dadurch gekennzeichnet, dass die Einprägungen von länglichen Vertiefungen gebildet werden, die auf jeweils einer Flachseite der Flachrohre vorgesehen sind.One Another preferred embodiment of the heat exchanger is characterized in that the imprints of elongated Wells are formed on each of a flat side of the Flat tubes are provided.
Ein weiteres bevorzugtes Ausführungsbeispiel des Wärmeübertragers ist dadurch gekennzeichnet, dass die Einprägungen von länglichen Vertiefungen gebildet werden, die jeweils auf beiden Flachseiten der Flachrohre vorgesehen sind. Damit wurden im Rahmen der vorliegenden Erfindung die besten Resultate erzielt.One Another preferred embodiment of the heat exchanger is characterized in that the imprints of elongated Wells are formed, each on both flat sides the flat tubes are provided. Thus were in the context of the present Invention achieves the best results.
Ein weiteres bevorzugtes Ausführungsbeispiel des Wärmeübertragers ist dadurch gekennzeichnet, dass die Einprägungen noppenartig ausgebildet sind. Als besonders vorteilhaft hat sich eine Kombination von länglichen mit noppenartigen Einprägungen auf beiden Flachseiten der Flachrohre erwiesen.One Another preferred embodiment of the heat exchanger is characterized in that the indentations formed knob-like are. Particularly advantageous is a combination of elongated with knob-like impressions proved on both flat sides of the flat tubes.

Im Rahmen der vorliegenden Erfindung werden hauptsächlich Flachrohre mit den Außenabmessungen 26,0 × 1,9 × 0,26 mm3 verwendet. Diese Flachrohre weisen eine lichte innere Rohrweite von 1,38 mm auf. Die Höhe der Einprägungen liegt im Bereich von 0,1 bis 0,4 mm. Durch die Höhe der Einprägungen kann der Wärmeübergang auf der Kühlmittelseite variiert werden, bis ein gewünschtes Leistungsresultat erzielt wird.In the context of the present invention, flat tubes with the outer dimensions 26.0 × 1.9 × 0.26 mm 3 are mainly used. These flat tubes have a clear inner tube width of 1.38 mm. The height of the impressions is in the range of 0.1 to 0.4 mm. Due to the height of the indentations, the heat transfer on the coolant side can be varied until a desired performance result is achieved.
