Abstract

The cooler has a displacement body (4) which is located in an outer tube (1) and carries a tube coil (5) for the petrol through flow. The outer tube comprises coolant connecting anions (2, 3) at its ends. The cooler must meet specified dimension requirements. The distance (a) between the pipe coil and the outer tube is 0.5 to 2 mm, and the distance (b) between adjacent turns of the pipe coil is 2 to 4 mm. The dia. (c) of the pipe coil is 5 to 9 mm.

Description

Die Erfindung betrifft einen Benzinkühler mitThe invention relates to a gasoline cooler with

  • a) einem Außenrohr, das zwei Anschlüsse für ein Kältemittel aufweist;a) an outer tube, the two connections for a refrigerant having;
  • b) einem koaxial innerhalb des Außenrohres verlaufenden Verdrängungskörper;b) extending coaxially within the outer tube Displacer;
  • c) einer auf der Mantelfläche des Verdrängungskörpers angeordneten, vom Benzin durchströmbaren Rohrwendel.c) one on the lateral surface of the displacement body arranged, permeable by gasoline coiled tubing.

Bei bekannten Benzinkühlern dieser Art, wie sie derzeit im Gebrauch sind, wurde regelmäßig ein maximaler Wirkungs­ grad angestrebt. Zwischenzeitlich hat sich jedoch heraus­ gestellt, daß durch derartige Benzinkühler dem Kühlsystem, bei Einbau des Benzinkühlers in Kraftfahrzeug also in der Regel der Klimaanlage dieses Kraftfahrzeuges, zuviel Leistung entnommen wird. Eine entsprechende Verkleinerung des Benzinkühlers insgesamt, die zu einer geringeren Kühlleistung führen würde, ergäbe jedoch Benzinkühler, die geometrisch nicht mehr in den bei dem jeweiligen Kraftfahrzeugen konstruktiv vorgesehenen Einbauraum passen würden.In known gasoline coolers of this kind, as currently in use, regularly became a maximum impact strived for. In the meantime, however, has turned out provided by such gasoline coolers the cooling system, when installing the gasoline radiator in motor vehicle so in the rule of the air conditioning of this motor vehicle, too much Power is taken. A corresponding reduction of the gasoline cooler in total, resulting in a lower Cooling performance would result, however, petrol cooler, the geometrically no longer in the case of the respective Motor vehicles structurally provided installation space would fit.

Aufgabe der vorliegenden Erfindung ist es, einen Benzin­ kühler der eingangs genannten Art so auszugestalten, daß unter Beibehaltung der Einbaumaße eine Kühlleistung erzielt wird, welche zur Kühlung des Benzines zuverlässig ausreicht, andererseits aber dem Kühlsystem nicht unnötig viel Wärme zuführt.Object of the present invention is a gasoline Cooler of the type mentioned above to design, that while maintaining the installation dimensions, a cooling capacity is achieved, which for cooling the gasoline reliable on the other hand, but the cooling system is not unnecessary supplies a lot of heat.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß folgende bauliche Abmessungen eingehalten sind:This object is achieved in that  the following structural dimensions are complied with:

Abstand (a) zwischen der Rohrwendel und dem Außenrohr|0,5-2,0 mmDistance (a) between the coiled tubing and the outer tube | 0.5-2.0 mm Abstand (b) zwischen benachbarten Windungen der RohrwendelDistance (b) between adjacent turns of coiled tubing 2,0-4,0 mm2,0-4,0 mm Rohrdurchmesser (c)Pipe diameter (c) 5,0-9,0 mm5.0-9.0 mm

Erfindungsgemäß wird also nicht der an und für sich naheliegende Weg beschritten, die Größe des Benzinküh­ lers zu reduzieren; vielmehr wird durch bestimmte kon­ struktive Abmessungen innerhalb des Benzinkühlers dessen Wirkungsgrad bewußt vom maximal Möglichen zurückgenommen und auf einen optimalen, dem Kühlbedarf angepaßten Wert eingestellt. Bevorzugt liegen die Werte für die Größen a, b, c zwischen 0,8 und 1,2 mm bzw. 2,5 bis 3,5 mm bzw. 6,0 bis 8,0 mm.Thus, according to the invention, it is not the case in and of itself approaching obvious, the size of Benzinküh lers to reduce; Rather, by certain con structural dimensions within the gas cooler of Efficiency deliberately withdrawn from the maximum possible and on an optimal, the cooling demand adjusted value set. The values for the sizes are preferably a, b, c between 0.8 and 1.2 mm and 2.5 to 3.5 mm or 6.0 to 8.0 mm.

Bei einem konkreten, besonders günstigen Ausführungsbei­ spiel liegen die Werte für die Größen a, b, c bei 1,0 mm bzw. 3,25 mm bzw. 6,0 mm.In a concrete, particularly favorable Ausführungsbei The values for the quantities a, b, c are 1.0 mm or 3.25 mm or 6.0 mm.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung näher erläutert; es zeigenAn embodiment of the invention will be below explained in more detail with reference to the drawing; show it

Fig. 1 die Seitenansicht eines Benzinkühlers; Fig. 1 is a side view of a gasoline cooler;

Fig. 2 einen Schnitt gemäß Linie II-II von Fig. 1. Fig. 2 shows a section according to line II-II of FIG. 1,.

Der in der Zeichnung dargestellte Benzinkühler umfaßt in an und für sich bekannter Weise ein Außenrohr 1, an dessen gegenüberliegenden Enden jeweils ein Anschluß 2, 3 für das Kältemittel befestigt ist. Dieses strömt über den in der Zeichnung rechten Anschluß 2 in das Innere des Außenrohres 1 ein und über den in der Zeich­ nung linken Anschluß 3 wieder aus. Der in der Zeichnung rechte Anschluß 2 ist als Steckanschluß, der linke An­ schluß 3 dagegen als Schraubgewindeanschluß ausgebildet.The gasoline cooler shown in the drawing comprises in a manner known per se, an outer tube 1 , at whose opposite ends in each case a terminal 2 , 3 is fixed for the refrigerant. This flows over the right in the drawing port 2 in the interior of the outer tube 1 and on the voltage in the drawing left connection 3 again. The right in the drawing port 2 is designed as a plug connection, the left-hand circuit 3, however, designed as a screw thread connection.

Im Innenraum des Außenrohres 1 ist ein konzentrischer, zylindrischer Verdrängungskörper 4 angebracht, welcher das über den Anschluß 2 zuströmende Kältemittel radial nach außen in den Ringraum zwischen dem Außenrohr 1 und dem Ver­ drängungskörper 4 leitet.In the interior of the outer tube 1 , a concentric, cylindrical displacement body 4 is mounted, which directs the inflowing via the port 2 refrigerant radially outward into the annular space between the outer tube 1 and the Ver urging 4 .

Auf der Mantelfläche des Verdrängungskörpers 4 ist unter elastischer Vorspannung eine Rohrwendel 5 aufgesetzt. Die Enden der Rohrwendel 5 sind radial durch das Außen­ rohr 1 hindurchgeführt und enden in Gewindeanschlüssen 6 und 7. Über die Gewindeanschlüsse 6 und 7 wird das zu kühlende Benzin durch die Rohrwendel 5 geleitet.On the lateral surface of the displacement body 4 , a coiled tubing 5 is placed under elastic bias. The ends of the tube coil 5 are radially passed through the outer tube 1 and terminate in threaded connections 6 and 7th About the threaded connections 6 and 7 , the gasoline to be cooled is passed through the tube coil 5 .

Diese Verhältnisse sind im Grundsatz alle an und für sich bekannt. Zur exakten Anpassung des Wirkungsgrades des dargestellten Benzinkühlers sind die Dimensionen der Rohrwendel 5 nunmehr wie folgt gewählt:These conditions are in principle all known in and of themselves. For exact adjustment of the efficiency of the illustrated gasoline cooler, the dimensions of the coiled tubing 5 are now selected as follows:

Rohrdurchmesser c|6 mmPipe diameter c | 6 mm Abstand a zwischen Rohrwendel 5 und Außenrohr 1 Distance a between tube coil 5 and outer tube. 1 1 mm1 mm Abstand b zwischen benachbarten Windungen der RohrwendelDistance b between adjacent turns of the coiled tubing 3,25 mm3.25 mm

Bei den genannten Dimensionen ergibt sich für den Benzin­ kühler ein Wirkungsgrad, der einerseits zur Kühlung des Benzines vollständig ausreicht, bei dem andererseits aber der Klimaanlage des Kraftfahrzeuges, dem das den Benzinkühler durchströmende Kältemittel entnommen ist, nicht zuviel Leistung entzogen wird.With the dimensions mentioned results for the gasoline cooler an efficiency, on the one hand for cooling of the gasoline is completely sufficient, on the other hand but the air conditioning of the motor vehicle, which the Gas cooler is flowed through refrigerant, not too much power is withdrawn.
