Definitions
- the invention relates to a coolant circuit of a motor vehicle drive unit with an air-coolant heat exchanger as well with at least one additional heat exchanger in which another medium, in particular hydraulic oil, can be tempered by the circulating coolant is, in the return of the air-coolant heat exchanger downstream of a branch to the additional heat exchanger is the coolant volume flow influencing valve is provided.
- A is known Coolant circuit of this type from EP 0 177 025 A2.
- the additional heat exchanger has an increased flow resistance is in the coolant circuit according to EP 0 177 025 A2 in Return of the air-coolant heat exchanger downstream of the branch to the additional heat exchanger that said the coolant volume flow influencing valve provided to also in this line branch to create certain flow resistance and thus ensure that at least a subset of the coolant flow over the other Line branch, namely via the additional heat exchanger.
- This known arrangement may well be suitable for certain applications may be sufficient, but in other cases it may be desirable to have one particularly intensive cooling of the additional medium in the additional heat exchanger to achieve.
- this additional medium can also coexist a hydraulic oil, for example in a turbocharger compressed and thus heated intake air designed as an internal combustion engine Act motor vehicle drive unit.
- Air-coolant heat exchanger here called additional cooler
- Air-coolant heat exchanger here called additional cooler
- the additional cooler forms a further flow resistance, so that the simple downstream of the branch to the additional heat exchanger provided and valve influencing the coolant volume flow, which is designed as a throttle in the above-mentioned EP 0 177 025 A2 is no longer sufficient to have a sufficient flow of coolant at all by the additional heat exchanger and by the upstream of this To lead additional cooler.
- this (additional) valve which downstream of the Branch to the additional heat exchanger is provided and the coolant volume flow influenced by the air-coolant heat exchanger, formed as a throttle valve biased in the closed position.
- a valve of this type flows, in particular, at a low delivery rate the pump provided in the coolant circuit and at at least partially opened thermostatic valve (so that coolant at all through the air-coolant heat exchanger) always a sufficient flow of coolant through the additional heat exchanger, whereas almost no coolant flow through the then in the substantially closed throttle valve arrives.
- reference numeral 1 designates an internal combustion engine functioning as a motor vehicle drive unit, which is water-cooled and the cooling liquid of which, as usual, can be recooled in an air-coolant heat exchanger 2, the flow of which is identified by the reference number 19.
- the cooling liquid is conveyed by a cooling liquid pump 3, which, as usual, is preceded by a thermostatic valve 4, with the aid of which the cooling liquid is either via the heat exchanger 2 or in the so-called small circuit "can be circulated bypassing the air-coolant heat exchanger 2.
- the direction of flow of the coolant is indicated by arrows.
- a heating heat exchanger 5 is provided in the coolant circuit, which is preceded by a control valve 6.
- Reference number 7 also denotes a conventional expansion tank, which is connected to the flow 19 of the air-coolant heat exchanger 2 is.
- a coolant bypass leads through this expansion tank 7 21 through, which branches from the lead 19, and which within the expansion tank 7 a so-called.
- Throttle branch 22 has.
- This so-called throttle branch 22, one opposite the coolant branch line 20 has a significantly smaller flow cross section has, the expansion tank 7 is thus as usual connected the entire coolant circuit.
- Another component of the coolant circuit is an additional heat exchanger 8, about the u. a. recooled coolant (from a branch 20 coming in the return 12 of the air-coolant heat exchanger 2) is feasible, and in which this is another medium, such as hydraulic oil / gear oil can cool.
- This additional heat exchanger 8 is also a thermostatic valve 9 upstream, in which the recooled coolant with non-recooled coolant - from said coolant bypass 21 coming - can be mixed in order in the additional heat exchanger 8 a desired temperature control of the one guided by it To be able to adjust the medium (hydraulic oil / gear oil).
- additional cooler 10 In order to cool the additional heat exchanger 8 particularly intensively To enable medium is the air-coolant heat exchanger 2 another so-called additional cooler 10 is connected downstream.
- This additional cooler 10 is thus in the lead 11 of the additional heat exchanger 8, in which the thermostatic valve 9 is provided and is from the return 12 of the Lutt coolant heat exchanger 2 from the branch 20 with coolant provided.
- the auxiliary cooler 10 which also functions as an air-coolant heat exchanger is formed, preferably forms with the actual air-coolant heat exchanger 2 a structural unit, as in the not previously published German patent application 196 37 818 is described.
- valve 13 does not exist, because of the flow resistance of the Additional cooler 10 and the additional heat exchanger 8 namely almost the complete exits from the air-coolant heat exchanger 2 Coolant flow directly (via the return 12) to the thermostatic valve 4 arrive, so that the additional heat exchanger 8 not at all would be flowed through.
- a suitable throttling effect of the valve 13 it is possible, however, a more or less large proportion of the Coolant flow also via the additional heat exchanger 8 to the coolant pump 3 attributed.
- valve 13 Only satisfactorily (additional) valve 13 if this Valve 13 as a throttle valve pretensioned in the closed position (cf. Fig. 2, reference numeral 14) is formed.
- this valve 13 or the corresponding throttle valve remains 14 almost closed, so that (when the thermostatic valve is open 4) the air-coolant heat exchanger 2 as desired after flowing through the coolant leaving it almost completely passed through the additional cooler 10 and via the additional heat exchanger 8 becomes.
- valve 13 designed as a throttle valve 14 is opened ever further, so that then the drive unit 1 or the internal combustion engine 1 on direct Ways (via the return 12) with a sufficient amount of im Air-coolant heat exchanger 2 recooled coolant supplied can be.
- Fig. 2 shows a cross section through the as biased in the closed position Throttle valve 14 formed valve 13, which with its valve housing 15 when the air-coolant heat exchanger 2 and the As already briefly mentioned, additional cooler 10 form a structural unit, preferably in the return nozzle of the air-coolant heat exchanger, not shown 2, to which the return 12 connects, can be arranged can.
- the throttle valve 14 is located on the valve housing 15 biasing torsion spring 16 biased, the throttle valve 14 over its axis of rotation 17 is desaxially mounted in the valve housing 15.
- acts the valve 13 or the throttle valve 14 with regard to coolant flow direction shown by an arrow 18 as Back pressure flap with respect to this flow due to said Desaxing, depending on the dynamic pressure, the desired opening of the throttle valve 14 or the valve 13 takes place.
- this valve 13 remains fully or partially closed and leads then, depending on the dynamic pressure, the desired throttle function.
- the throttle valve 14 itself can be made of brass, while the flap housing 15 and the torsion spring 16, the spring characteristics of which determine the throttle behavior of the valve 13, can be made of stainless steel.
- this and a large number of further details can be designed quite differently from the exemplary embodiment shown, without leaving the content of the patent claims.

Abstract
Description
Ebenfalls wie üblich ist im Kühlflüssigkeitskreislauf ein Heizungswärmetauscher 5 vorgesehen, dem ein Regelventil 6 vorgeschaltet ist.
Die Drosselklappe 14 selbst kann in Messing ausgeführt sein, während das Klappengehäuse 15 und die Drehfeder 16, deren Federcharakteristik des Drosselverhalten des Ventiles 13 bestimmt, in Edelstahl ausgeführt sein können. Jedoch kann dies sowie eine Vielzahl weiterer Details durchaus abweichend vom gezeigten Ausführungsbeispiel gestaltet sein, ohne den Inhalt der Patentansprüche zu verlassen. Stets erhält man mit geeigneter Auslegung der Vorspannung der Drosselklappe 14 in Schließstellung (beispielsweise durch die besagte Drehfeder 16) eine optimale Aufteilung des Kühlmittelstroms einerseits auf den direkt zum Thermostatventil 4 führenden Rücklauf 12, als auch andererseits auf den über den Zusatzkühler 10 sowie den Zusatzwärmetauscher 8 zur Kühlflüssigkeitspumpe 3 geführten Leitungszweig.
