Abstract
Description
Die Erfindung betrifft einen Wärmeaustauscher mit einer Mehrzahl von übereinander angeordneten ersten Durchgängen für ein Kühlmedium und zwischen diesen angeordneten, an ihren Enden mit Sammelkästen versehenen zweiten Durchgängen für ein zu kühlendes Medium, wobei die ersten und zweiten Durchgänge jeweils durch Platten und diese auf Abstand haltende, längs der seitlichen Ränder der Platten erstreckte, erste und zweite Blockprofile gebildet sind und wobei die die ersten Durchgänge begrenzenden ersten Blockprofile im wesentlichen senkrecht zu den die zweiten Durchgänge begrenzenden zweiten Blockprofilen angeordnet sind.The The invention relates to a heat exchanger with a plurality of one above the other arranged first passes for a cooling medium and arranged between them, provided with collecting boxes at their ends second passes for a to be cooled Medium, wherein the first and second passages respectively through plates and these at a distance, longitudinally the lateral edges the plates extended, first and second block profiles are formed and being the first passages delimiting first block profiles substantially perpendicular to the the second passes limiting second block profiles are arranged.
Wärmeaustauscher
dieser Art werden z. B. bei Ladeluftkühlern von Kraftfahrzeugen dazu
benötigt,
die auf Temperaturen von über
200°C erhitzte, die
zweiten Durchgänge
durchströmende
Ladeluft mit Hilfe eines die ersten Durchgänge durchströmenden Kühlmittels
in Form von Wasser oder Luft abzukühlen. Daneben sind Wärmeaustauschernetze
bekannt (
Zur
Vermeidung dieses Nachteils ist es bekannt (
Bei verschiedenen Anwendungszwecken ist es außerdem erwünscht, die zweiten Durchgänge derartiger Wärmeaustauscher mit vergleichsweise hohen Drücken von z. B. 2,6 bar und mehr und entsprechend großen Strömungsgeschwindigkeiten zu betreiben, beispielsweise wiederum bei ihrer Anwendung als Ladeluftkühler für Kraftfahrzeuge. Dabei hängt die bei der Durchströmung des Wärmeaustauschers bzw. der zweiten Durchgänge erzielbare Kühl- bzw. Wärmeaustauschleistung von dem insgesamt tolerierbaren Druckabfall ab. Da ein großer Teil der Druckverluste in den zweiten Durchgängen konstruktionsbedingt durch die Übergangsbereiche zwischen diesen und den Sammelkästen verursacht wird, sind die auf das Wärmeaustauschernetz selbst entfallenden und zur Erzielung der geforderten Wärmeaustauschleistungen nutzbaren Anteile des Druckabfalls begrenzt.at In addition, for various applications, it is desirable to have the second passes of such heat exchangers with comparatively high pressures from Z. B. 2.6 bar and more and operate correspondingly large flow velocities, for example, again when used as a charge air cooler for motor vehicles. It hangs the at the flow of the heat exchanger or the second passes achievable cooling or Heat exchange performance from the total tolerable pressure drop. Because a big part the pressure losses in the second passages by design the transition areas between these and the collection boxes caused are those attributable to the heat exchanger network itself and usable to achieve the required heat exchange performance Shares of pressure drop limited.
Bei
aus Rohren hergestellten Wärmeaustauschern
sind bereits zahlreiche Einrichtungen vorgeschlagen worden, die
Druckverluste in den Übergangsbereichen
zwischen den zweiten Durchgängen und
den Sammelkästen
weitgehend vermeiden und dadurch bewirken sollen, daß der längs des
Wärmeaustauschers
tolerierbare Druckabfall überwiegend in
den Durchgängen
des Wärmetauschernetzes
genutzt werden kann. Es ist z. B. bekannt (
Bei
anderen bekannten Wärmeaustauschern [
Nachteilig an diesen Vorschlägen ist außerdem, daß sie anschließlich aus Rohren, aber keine aus Platten und Blockprofilen und damit preisgünstig herstellbare Wärmeaustauscher betreffen.adversely on these proposals is also that she anschließlich made of pipes, but none of plates and block profiles and thus inexpensive to produce heat exchangers affect.
Bei
Plattenwärmeaustauschern
für Haushaltswäschetrockner
ist es schließlich
bekannt (
Ausgehend von diesem Stand der Technik liegt der Erfindung das technische Problem zugrunde, einen preisgünstig herstellbaren Wärmeaustauscher zur Verfügung zu stellen, der sowohl zu einer Reduzierung der Druckverluste in dem Übergangsbereich zwischen dem Sammelkasten und den vom zu kühlenden Medium durchströmten Durchgängen führt als auch für Hochtemperatur-Anwendungen eingerichtet und dazu insbesondere mit einer erhöhten Festigkeit gegenüber Temperaturwechseln versehen werden kann.outgoing From this prior art, the invention is the technical Problem, a reasonably priced producible heat exchanger to disposal to reduce both the pressure losses in the transition area between the collection box and the flow-through of the medium to be cooled passes as also for High-temperature applications and especially with an increased strength across from Temperature changes can be provided.
Die Erfindung geht zur Lösung dieses Problems vom Wärmeaustauscher der eingangs angegebenen Gattung aus, wobei die ersten Blockprofile dieses Wärmeaustauschers entsprechend dem Kennzeichenteil des Anspruchs 1 gestaltet werden.The Invention goes to the solution this problem of the heat exchanger of the type specified above, the first block profiles this Heat exchanger accordingly The characterizing part of claim 1 are designed.
Die
Erfindung ermöglicht
eine bisher nur bei Röhren-Wärmeaustauschern
mögliche
Reduzierung der Druckverluste in den zweiten Durchgängen speziell
bei Platen-Wärmeaustauschern.
Gemäß einem besonders
bevorzugten Ausführungsbeispiel

Durchgängen
