Abstract
Description
Die Erfindung betrifft einen Wärmeübertrager, insbesondere einen Heizkörper, für eine Klimaanlage eines Kraftfahrzeugs, der eine Vielzahl von aufeinander gestapelten, scheibenförmigen Rohren umfasst, die von einem ersten Medium, insbesondere von Kühlmittel, durchströmt sowie von einem zweiten Medium, insbesondere von Luft, umströmt werden, und die aus jeweils zwei Halbschalen gebildet sind, die jeweils mindestens einen Verbindungsnapf aufweisen, der eine Napfhöhe aufweist und dazu dient, die scheibenförmigen Rohre, die in Stapelrichtung eine lichte Rohrweite aufweisen, miteinander zu verbinden.The Invention relates to a heat exchanger, especially a radiator, for one Air conditioning of a motor vehicle, a variety of successive stacked, disc-shaped Comprises pipes made of a first medium, in particular of coolant, flows through and by a second medium, in particular of air, to be flowed around, and which are each formed of two half-shells, respectively have at least one connecting cup having a cup height and serves the disc-shaped Tubes, which have a clear pipe width in the stacking direction, with each other connect to.
Bei der Entwicklung von Wärmeübertragern wird versucht, eine große Querteilung zu realisieren, um die Anzahl der zwischen zwei Rohren vorzugsweise vorgesehenen Wellrippen aus Kostengründen möglichst klein zu halten.at the development of heat exchangers becomes trying a big one To realize transverse division to the number of between two pipes preferably provided corrugated fins for cost reasons possible to keep small.
Aufgabe der Erfindung ist es, einen Wärmeübertrager gemäß dem Oberbegriff des Anspruchs 1 zu schaffen, der kostengünstig herstellbar ist.task The invention is a heat exchanger according to the generic term of claim 1 to create, which is inexpensive to produce.
Die Aufgabe ist bei einem Wärmeübertrager, insbesondere einem Heizkörper, für eine Klimaanlage eines Kraftfahrzeugs, der eine Vielzahl von aufeinander gestapelten, scheibenförmigen Rohren umfasst, die von einem ersten Medium, insbesondere von Kühlmittel, durchströmt sowie von einem zweiten Medium, insbesondere von Luft, umströmt werden, und die aus jeweils zwei Halbschalen gebildet sind, die jeweils mindestens einen Verbindungsnapf aufweisen, der eine Napfhöhe aufweist und dazu dient, die scheibenförmigen Rohre, die in Stapelrichtung eine lichte Rohrweite aufweisen, miteinander zu verbinden, dadurch gelöst, dass das Verhältnis zwischen der Napfhöhe und der Rohrweite größer als 2,25 ist. Durch dieses Verhältnis kann der luftseitige Druckverlust gering gehalten werden.The Task is with a heat exchanger, in particular a radiator, for one Air conditioning of a motor vehicle, a variety of successive stacked, disc-shaped Comprises pipes made of a first medium, in particular of coolant, flows through and by a second medium, in particular of air, are flowed around, and which are each formed of two half-shells, each at least have a connecting cup, which has a cup height and serves to, the discoid Tubes, which have a clear pipe width in the stacking direction, with each other to be solved, that the ratio between the cup height and the pipe width is greater than 2.25 is. By this ratio the air-side pressure loss can be kept low.
Ein bevorzugtes Ausführungsbeispiel des Wärmeübertragers ist dadurch gekennzeichnet, dass das Verhältnis zwischen der Napfhöhe und der Rohrweite kleiner als 3 ist. Der erfindungsgemäße Wärmeübertrager weist im Vergleich zu herkömmlichen Wärmeübertragern eine eher kleine Querteilung auf. Daher ist der erfindungsgemäße Wärmeübertrager mit mehr Wellrippen ausgestattet als herkömmliche Wärmeübertrager, was sich ungünstig auf die Herstellkosten auswirkt. Aber dieser Nachteil wird bewusst in Kauf genommen, da die sich aus dem erfindungsgemäßen Verhältnis ergebende eher geringe Napfhöhe mit relativ einfachen Werkzeugen erzeugt werden kann.One preferred embodiment of the heat exchanger is characterized in that the relationship between the cup height and the Pipe width is less than 3. The heat exchanger according to the invention has in comparison to conventional heat exchangers a rather small cross distribution. Therefore, the heat exchanger according to the invention with more corrugated fins equipped than conventional heat exchangers, which is unfavorable the manufacturing costs. But this disadvantage will be aware of Purchase, since the resulting from the ratio of the invention rather small cup height with relative simple tools can be produced.
Ein weiteres bevorzugtes Ausführungsbeispiel des Wärmeübertragers ist dadurch gekennzeichnet, dass die Napfhöhe 1,5 bis 4,0 mm, insbesondere 2,0 bis 3,0 mm, beträgt. Die Realisierung dieser Napfhöhen kann in deutlich weniger Stufen realisiert werden als die bei herkömmlichen Wärmeübertragern üblichen Napfhöhen.One Another preferred embodiment of the heat exchanger is characterized in that the cup height 1.5 to 4.0 mm, in particular 2.0 to 3.0 mm. The realization of these cup heights can be realized in much less steps than conventional ones Heat exchangers usual Napf Hills.
Ein weiteres bevorzugtes Ausführungsbeispiel des Wärmeübertragers ist dadurch gekennzeichnet, dass die Rohrweite 0,4 bis 3,0 mm, insbesondere 0,6 bis 1,6 mm, beträgt. Je geringer die Rohrweite ist, desto höher ist der Druckverlust in dem Rohr. Allerdings wirkt sich die geringe Rohrweite positiv auf die Geschwindigkeit des Kühlmittels in dem Rohr und auf den Wärmeübergang aus.One Another preferred embodiment of the heat exchanger is characterized in that the pipe width 0.4 to 3.0 mm, in particular 0.6 to 1.6 mm. The smaller the pipe width, the higher the pressure loss in the pipe. However, the small pipe width has a positive effect the speed of the coolant in the pipe and on the heat transfer out.
Ein weiteres bevorzugtes Ausführungsbeispiel des Wärmeübertragers ist dadurch gekennzeichnet, dass die Halbschalen noppenartige Vertiefungen oder Erhöhungen der Halbschalen aufweisen, die so gestaltet sind, dass die noppenartigen Vertiefungen oder Erhöhungen der Halbschalen eines Rohres aneinander anliegen. Durch die Noppenstruktur werden der Wärmeübergang auf der Rohrinnenseite und die Druckfestigkeit der Rohre verbessert.One Another preferred embodiment of the heat exchanger is characterized in that the half-shells knob-like depressions or raises the half-shells, which are designed so that the knob-like depressions or raises the half shells of a tube abut each other. Through the nub structure become the heat transfer on the inside of the pipe and the pressure resistance of the pipes improved.
Ein weiteres bevorzugtes Ausführungsbeispiel des Wärmeübertragers ist dadurch gekennzeichnet, dass die noppenartigen Vertiefungen oder Erhöhungen an ihrer Basis einen Durchmesser von 0,8 bis 3,5 mm, insbesondere 1,0 bis 2,0 mm, aufweisen. Diese Durchmessergrößen haben sich im Rahmen der vorliegenden Erfindung als besonders vorteilhaft erwiesen.One Another preferred embodiment of the heat exchanger is characterized in that the knob-like depressions or raises at its base a diameter of 0.8 to 3.5 mm, in particular 1.0 to 2.0 mm. These diameter sizes have become part of the present invention proved to be particularly advantageous.
Ein weiteres bevorzugtes Ausführungsbeispiel des Wärmeübertragers ist dadurch gekennzeichnet, dass an den Halbschalen jeweils mindestens zwei Positionierlaschen angebracht sind. Die Laschen dienen dazu, die Halbschalen vor dem Verlöten zu fixieren.One Another preferred embodiment of the heat exchanger is characterized in that at the half shells in each case at least two positioning tabs are attached. The tabs serve the half-shells before soldering to fix.
Ein weiteres bevorzugtes Ausführungsbeispiel des Wärmeübertragers ist dadurch gekennzeichnet, dass die beiden ein Rohr bildenden Halbschalen jeweils einstückig miteinander verbunden sind. Dadurch wird die Herstellung des Wärmeübertragers weiter vereinfacht.One Another preferred embodiment of the heat exchanger is characterized in that the two half-shells forming a tube each in one piece connected to each other. This will produce the heat exchanger further simplified.
