Abstract
Wärmetauscher, insbesondere Ölkühler für Kraftfahrzeuge, aufgebaut aus ineinander gestapelten, wannenförmigen Wärmetauscherplatten (10) und aus Turbulenzeinlagen (5), mit zwei Öffnungen (31) für das eine Medium und zwei weiteren Öffnungen (21) für das andere Medium, zur Bildung von Sammelkanälen (30, 20) für die Zu- und Ableitung der Medien, wobei zwischen den Wärmetauscherplatten (10) Strömungskanäle (8 und 9) für die Medien ausgebildet sind, die mit den zugeordneten Sammelkanälen (30, 20) in Verbindung stehen, sowie aus einer oberen Abschlussplatte (12), welche im Bereich der Sammelkanäle (30) Auswölbungen (6) besitzt, und aus einer mit Löchern (2, 3) versehenen Zwischenplatte (11) dadurch gekennzeichnet, dass die Zwischenplatte (11) zwischen der Abschlussplatte (12) und der obersten Wärmetauscherplatte (10) angeordnet ist, und dass das eine der Löcher (2) als Druckausgleichsöffnung mit der nach oben gerichteten Auswölbung (6) in der Abschlussplatte zusammenwirkt, wobei ein Durchmesser (D) des Loches (2) im Zwischenblech (11) wesentlich kleiner ist als ein Durchmesser des Sammelkanals (30).Heat exchangers, in particular oil coolers for motor vehicles, constructed of trough-shaped, trough-shaped heat exchanger plates (10) and of turbulence inserts (5), with two openings (31) for the one medium and two further openings (21) for the other medium, for forming collection channels (30, 20) for the supply and discharge of the media, wherein between the heat exchanger plates (10) flow channels (8 and 9) are formed for the media, which communicate with the associated collecting channels (30, 20), as well as from a upper end plate (12), which in the region of the collecting channels (30) has bulges (6), and of a holes (2, 3) provided with the intermediate plate (11), characterized in that the intermediate plate (11) between the end plate (12) and the uppermost heat exchanger plate (10) is arranged, and that one of the holes (2) as a pressure equalization opening with the upwardly directed bulge (6) zusammenwi in the end plate Rkt, wherein a diameter (D) of the hole (2) in the intermediate plate (11) is substantially smaller than a diameter of the collecting channel (30).
Description
Die Erfindung betrifft einen Wärmetauscher gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a heat exchanger according to the preamble of
Aus der
Aus dem
Die
Die Aufgabe der Erfindung besteht darin, die Widerstandsfähigkeit des Wärmetauschers gegen Innendruck weiter zu verbessern.The object of the invention is to further improve the resistance of the heat exchanger to internal pressure.
Die erfindungsgemäße Lösung der Aufgabenstellung ergibt sich bei dem gattungsgemäßen Wärmetauscher, durch dessen Weiterbildung entweder gemäß den Merkmalen aus dem Kennzeichen des Anspruchs 1 oder gemäß den Merkmalen aus dem Kennzeichen des Anspruchs 10.The inventive solution of the problem arises in the generic heat exchanger, by its development either according to the features of the characterizing part of
Weil die Zwischenplatte zwischen der Abschlussplatte und der obersten Wärmetauscherplatte angeordnet ist, und weil wenigstens eines der Löcher darin als Druckausgleichsöffnung mit der nach oben gerichteten Auswölbung in der Abschlussplatte zusammenwirkt, ist der Wärmetauscher jetzt auch für Innendrücke geeignet, die deutlich über 10 bar hinausgehen. Die Druckausgleichsöffnung gestattet beispielsweise dem Öl, in den Raum zwischen der Auswölbung und der Zwischenplatte einzutreten und dort eine Kraft zu entfalten, die der Kraft, die zwischen der Wärmetauscherplatte und der Zwischenplatte wirkt, entgegengerichtet ist. Es wird somit eine gewisse Entlastung erreicht.Because the intermediate plate is located between the end plate and the uppermost heat exchanger plate, and because at least one of the holes therein cooperates as a pressure equalization port with the upturned protrusion in the end plate, the heat exchanger is now also suitable for internal pressures well above 10 bar. The pressure equalization port, for example, allows the oil to enter the space between the protrusion and the intermediate plate to develop a force thereon that opposes the force acting between the heat exchanger plate and the intermediate plate. It is thus achieved a certain relief.
Eine Entlastung wird erfindungsgemäß auch dadurch erreicht, dass die Abschlussplatte durch eine die Auswölbung aufweisende Verschlussscheibe ersetzt ist, die mit der Zwischenplatte verbunden ist, wobei der Durchmesser der Auswölbung größer ist als der Durchmesser des Sammelkanals, wobei die Zwischenplatte an der obersten Wärmetauscherplatte angeordnet ist. Der alternative Lösungsvorschlag verzichtet also komplett auf die Abschlussplatte und setzt lediglich eine Verschlussscheibe ein, die etwas größer ist als der Kanal, den sie verschließt. Die Größe des Durchmessers der Druckausgleichsöffnung D liegt im Bereich von 1 mm bis 10 mm, vorzugsweise im Bereich von 1 mm bis 2 mm. Die Abschlussplatte und die Zwischenplatte können unterschiedliche Dicken a und z aufweisen. Diese Werte liegen für die Dicke a im Bereich von 1 mm bis 3 mm und für die Dicke z im Bereich von 1 mm bis 2 mm. Die Auswölbungen in der Abschlussplatte weisen einen größeren Durchmesser auf als die Sammelkanäle der Medien. Eine Alternative oder eine ergänzende Möglichkeit, die Innendruckstabilität zu erhöhen, besteht darin, das vorletzte Turbulenzblech, das im Strömungskanal des einen Mediums liegt, so auszugestalten, dass es keine Öffnung wie die anderen Turbulenzbleche aufweist. Ein vorzugsweise kleines Loch kann im Bereich des Sammelkanals allerdings im Turbulenzblech vorhanden sein, das die Funktion als Druckausgleichsöffnung besitzt. Die unterste Wärmetauscherplatte ist aus einem dickeren Blech als die anderen Wärmetauscherplatten gebildet. Eine Befestigungsplatte ist mindestens zweiteilig ausgebildet.A relief is inventively also achieved in that the end plate is replaced by a bulge having closure disk, which is connected to the intermediate plate, wherein the diameter of the bulge is greater than the diameter of the collecting channel, wherein the intermediate plate is disposed on the uppermost heat exchanger plate. The alternative solution thus completely dispenses with the end plate and only uses a shutter disc, which is slightly larger than the channel that it closes. The size of the diameter of the pressure compensation opening D is in the range of 1 mm to 10 mm, preferably in the range of 1 mm to 2 mm. The end plate and the intermediate plate may have different thicknesses a and z. These values are in the range of 1 mm to 3 mm for the thickness a and in the range of 1 mm to 2 mm for the thickness z. The bulges in the end plate have a larger diameter than the collecting channels of the media. An alternative or complementary way to increase the internal pressure stability is to design the penultimate turbulence plate, which is located in the flow channel of the one medium, that it has no opening like the other turbulence plates. However, a preferably small hole may be present in the region of the collecting channel in the turbulence plate, which has the function of a pressure equalization opening. The lowermost heat exchanger plate is formed of a thicker sheet than the other heat exchanger plates. A mounting plate is formed at least in two parts.
