Definitions

  • the invention relates to a cooling device with at least two cooling circuits which are connected to a common expansion tank for coolant.
  • the invention also relates to a vehicle, preferably a utility vehicle, and / or a stationary system with such a cooling device.
  • Cooling circuits are used to remove excess heat from self-heating or externally heated components.
  • a coolant e.g. oil, water or a water-cooling water additive mixture
  • cooling circuits can often be provided, in particular several cooling circuits that operate at different temperature levels.
  • a high-temperature circuit for cooling the internal combustion engine with a high temperature level of over 90 ° C. in normal operation and a low-temperature circuit for cooling the electric drive system with a low temperature level.
  • a low-temperature circuit for cooling the electric drive system with a low temperature level.
  • vehicles with indirect charge air cooling to use a high-temperature circuit to cool the internal combustion engine with a high temperature level of over 90 ° C in normal operation and a low-temperature circuit to cool the charge air at a low temperature level.
  • the coolant that has accumulated in the expansion tank is returned to the corresponding cooling circuit via a filling line that connects the expansion tank with the corresponding cooling circuit.
  • the documents are an example in this context DE 199 12 138 A1 , DE 10 2007 052 927 A1 , WO 03/042516 A2 and DE 10 2007 054 855 A1 referenced, all of which show such expansion tanks connected to several cooling circuits.
  • a common expansion tank is provided for several cooling circuits operating at different temperature levels, the different temperature coolants can be mixed in the expansion tank. Via the corresponding filling line, warmer coolant would then be introduced from the common expansion tank into a cooling circuit with a lower temperature level, which could restrict its functionality or lead to damage to the components contained therein.
  • the approach is also known in the prior art to modify the expansion tank in such a way as to avoid mixing of the coolants.
  • the laid-open specification discloses DE 2 063 298 A1 a common expansion tank for a motor vehicle with two separate cooling circuits, which has an absolutely tight partition.
  • two separate areas for receiving coolant of a cooling circuit are formed and there is no exchange of coolant between the cooling circuits.
  • this approach does not allow pressure equalization between the various cooling circuits and makes it more difficult to fill or introduce additives into the coolant, since all components (nozzles, silicate depot, etc.) have to be designed several times.
  • the prior art also uses the approach of mixing the coolant in the various cooling circuits and thus allowing the temperature levels to be adjusted in the common expansion tank, but precooling the coolant at a lower temperature level before it enters the cooling circuit.
  • the laid-open specification discloses this DE 10 2015 212 554 A1 a motor vehicle with two Cooling circuits at different temperature levels, in which the coolant in the filling line is passed through a heat exchanger at a lower temperature before entering the cooling circuit.
  • heat exchanger heat is transferred from the coolant, which flows in the filling line from the expansion tank to the cooling circuit, to the coolant, which is in the The vent line from the cooling circuit to the expansion tank flows. Since the media flowing through the heat exchanger are therefore coolants in both cases, only a low cooling capacity is achieved due to the relatively small temperature difference between the two media. In addition, there is an undesirable introduction of heat into the overall system.
  • a basic idea of the invention is to use an air-cooled heat exchanger for cooling the filling line, which achieves a higher cooling capacity due to the higher temperature difference between ambient air and coolant, and to integrate this heat exchanger into existing components of the cooling circuit in a space-saving manner.
  • a cooling device with at least two cooling circuits is provided for this purpose, each of which is connected to a common expansion tank for coolant via at least one ventilation line and at least one filling line.
  • Two of the cooling circuits preferably work at different temperature levels.
  • An air-cooled heat exchanger is provided on at least one of the filling lines, by means of which the coolant is precooled before it enters the cooling circuit assigned to this filling line.
  • the air-cooled heat exchanger can be provided at any point on the filling line, preferably in a central area of the filling line. This means that coolant can first enter a first area of the filling line, then pass through the air-cooled heat exchanger, then flow through a second area of the filling line until it finally enters the cooling circuit.
  • cooling circuit can be understood in this context to mean that it consists of a system connected via corresponding pipes, hoses or lines comprises several coolant pumps, coolant coolers and heat exchangers, in which coolant, preferably water, oil or a water-cooling water additive mixture, driven by the coolant pump, circulates almost closed.
  • coolant preferably water, oil or a water-cooling water additive mixture
  • the cooling circuit preferably absorbs excess heat from self-heating or externally heated components, such as an internal combustion engine, electric motor or battery, via the heat exchanger and releases it to the ambient air by means of the coolant cooler.
  • a ventilation line is understood to be a fluid line, e.g. a pipe or hose connection, which connects a cooling circuit, preferably at its geodetically highest point, with the expansion tank, which is preferably arranged at an even higher level. Gases, vapors, expanding coolant and / or a coolant-air mixture can be conveyed from the cooling circuit to the expansion tank via the vent line. In other words, the diverted coolant is mainly transported from the cooling circuit to the expansion tank in the vent line.
  • the vent line can consist of a plastic, metal or other suitable material.
  • Expansion tanks for coolants are known per se in the prior art and are used, on the one hand, to vent a cooling circuit. In addition, they can compensate for thermally induced changes in the volume of the coolant in a cooling circuit by temporarily storing expanding and thus excess coolant there.
  • an expansion tank can have a coolant reservoir in the form of one or more coolant chambers for receiving the expanding coolant.
  • the expansion tank can comprise an overpressure and / or underpressure valve for pressure regulation as well as a filler opening for coolant with an associated closure cap.
  • the expansion tank can comprise devices for introducing additives into the coolant, for example a silicate deposit.
  • a filling line is understood to be a fluid line, for example a pipe or hose connection, which leads from the expansion tank, preferably from a geodetically lower area of the expansion tank, back to the, preferably lower lying, cooling circuit.
  • the filling line is used to guide the coolant that has accumulated in the expansion tank back into the cooling circuit, whereby the substance transport in the filling line mainly takes place from the expansion tank to the cooling circuit.
  • the cooling circuit is also preferably filled for the first time or re-filled with coolant via the filling line.
  • the filling line can be turned off a plastic, metal or other suitable material and preferably flows into the cooling circuit at a point shortly before, ie upstream, the coolant pump.
  • cooling circuits are each connected to a common expansion tank for coolant via at least one vent line and at least one filling line.
  • all cooling circuits connected to the common expansion tank operate at almost the same temperature level.
  • further cooling circuits with their own expansion tanks, filling and venting lines can also be present in the cooling device.
  • the exact structural embodiment of the expansion tank (s) is not relevant for the device according to the invention.
  • the expansion tank can be designed in one piece or in several parts and comprise one or more coolant chambers.
  • the coolant chambers can be connected via through openings and thus enable the coolant of the different cooling circuits to be mixed, or they can be separated from one another by tight partition walls, so that there can be no exchange of coolant between the different cooling circuits in the expansion tank.
  • the invention is particularly advantageous if several cooling circuits at different temperatures are connected to an expansion tank and the coolant flows are mixed there.
  • an air-cooled heat exchanger is provided, preferably on the filling line of the cooling circuit with a lower temperature level, which pre-cools the coolant before it enters the cooling circuit .
  • the air-cooled heat exchanger can be designed in a form known per se in the prior art, the heat extracted from the coolant being released to the ambient air at the end.
  • the air-cooled heat exchanger can be a tube bundle cooler or a tube cooler.
  • the air-cooled heat exchanger can also include cooling fins and / or heat sinks. Since the operating temperature of the cooling circuits in common applications, e.g. in the automotive sector, is usually well above the ambient air temperature - for example, the temperature of a cooling circuit of an internal combustion engine in normal operation is> 90 ° C - the use of air as the heat exchange medium advantageously results in a high temperature difference and thus achieves a high cooling capacity.
  • the air-cooled heat exchanger is designed as a first sub-area of a coolant cooler, which is separated from a second sub-area of the coolant cooler. Both the first and the second sub-area have their own inlet and outlet for coolant.
  • the coolant cooler can be designed in a form known per se in the prior art, for example as a downdraft or cross-flow cooler.
  • the coolant cooler can comprise a plurality of cooling passages or cooling tubes that are cooled by the ambient air flowing past.
  • the term separated is to be understood in such a way that the two areas within the coolant cooler are not fluidically connected on the coolant side.
  • the coolant cooler understood as a component, can thus assume a double function.
  • a partial area of the coolant cooler is used to cool coolant before it enters the cooling circuit.
  • a partial area of the coolant cooler is used to cool the coolant that circulates in the cooling circuit.
  • the volumes of the two areas of the coolant cooler outside the coolant cooler can be fluidically connected via corresponding lines or the expansion tank. That is to say, coolant can first pass through the first area of the coolant cooler, then enter the cooling circuit and, in the course of the circulation, get there into the second area of the coolant cooler.
  • there cannot be any fluidic connection between the two areas of the coolant cooler that is, neither inside nor outside of the coolant cooler.
  • the coolant cooler comprises a plurality of tubes, preferably flat tubes. Of these pipes, a first subset is assigned to the first sub-area and a second subset is assigned to the second sub-area, the two pipe sub-sets in the coolant cooler not being fluidically connected and the first sub-set being smaller than the second sub-set.
  • the coolant cooler can be designed as a downdraft or cross-flow cooler and can comprise a soldered cooler network consisting of a plurality of flat tubes and cooling fins. A small portion of these flat tubes can be used to cool the coolant in the filling line, while the remaining flat tubes of the coolant cooler are used to cool the coolant in the cooling circuit.
  • 10% of the tubes can be used to cool the filling line and the remaining 90% of the tubes can be used to cool the coolant circulating in the cooling circuit.
  • the advantage of this embodiment is that a coolant cooler required for the proper functioning of the cooling circuit can be expanded to the dual function according to the claims without great loss of cooling performance.
  • the coolant cooler comprises a first cooling section, which is assigned to the first sub-area, and a second cooling section, which is assigned to the second sub-area, the two cooling sections in the coolant cooler not being fluidically connected and the first cooling section being shorter than the second cooling section.
  • This embodiment is particularly advantageous if it is a heat exchanger with two or more cooling sections or if the coolant cooler comprises meandering channels.
  • the first and second cooling sections can also be of the same length, which is particularly advantageous if the coolant cooler is a downward or cross-flow cooler.
  • the first sub-area of the coolant cooler adjoins the second sub-area of the coolant cooler or is arranged adjacently.
  • the first and second sub-areas can be in direct mechanical contact with one another, i.e. they can abut one another and thus be regarded as one component, as it were.
  • the two areas can only be separated from one another via a partition.
  • the cooling fan which is usually installed on the coolant cooler, can also ensure a circulation of the ambient air and thus efficient cooling on the filling line.
  • coolant from the expansion tank is supplied to the inlet of the first sub-region of the coolant cooler via the filling line of the associated cooling circuit.
  • coolant from the expansion tank first runs through the filling line and then enters the air-cooled heat exchanger, which is designed as a first sub-area of a coolant cooler, via the inlet.
  • the coolant is cooled, which then enters the cooling circuit after exiting the heat exchanger, whereby it can pass a further section in the filling line beforehand.
  • the outlet of the first sub-area of the coolant cooler is upstream of the inlet of the second sub-area of the coolant cooler. That is, in normal operation, coolant flows from the outlet of the first sub-region of the coolant cooler to the Inlet of the second sub-region of the coolant cooler, the coolant being able to flow through or along further components, for example a coolant pump or the components to be cooled, in the meantime.
  • the inlet and / or outlet of the heat exchanger is designed as a hose connector or as a hose coupling.
  • the opening for supplying the coolant into the heat exchanger is understood as the inlet, and the opening for the coolant to escape from the heat exchanger as the outlet.
  • the heat exchanger can also comprise more than one inlet and more than one outlet.
  • the inlet and / or outlet of the heat exchanger can also comprise a pipe coupling and / or flange connection.
  • the air-cooled heat exchanger is designed as a separate component which is only provided for cooling the coolant in the filling line.
  • the heat exchanger is explicitly not designed as a sub-area of a coolant cooler.
  • the heat exchanger can be designed as an air-cooled tube bundle cooler, tube cooler or heat exchanger.
  • the heat exchanger can comprise cooling fins and / or heat sinks.
  • This embodiment is further characterized in that a coolant cooler of the associated cooling circuit is arranged downstream of the filling line.
  • the coolant in the filling line passes through an air-cooled heat exchanger at one point on its way from the expansion tank to the entry into the cooling circuit and then a coolant cooler in the cooling circuit, which is not identical to the aforementioned air-cooled heat exchanger.
  • the advantage of this variant is that, due to the spatial separation of the heat exchanger and coolant cooler, no heat transfer can occur between the two components.
  • an undesired heat flow of the coolant which is initially warm when entering the heat exchanger, is effectively prevented via the heat exchanger and coolant cooler wall to the cold cooling circuit.
  • exactly two cooling circuits operating at different temperature levels are each connected to a common expansion tank for coolant via at least one vent line and at least one filling line.
  • the air-cooled heat exchanger is provided on the filling line of the cooling circuit with a lower temperature level in order to precool the coolant from the common expansion tank before it enters the cooling circuit with a lower temperature level. In this way, warm coolant is advantageously prevented from being introduced into the cooling circuit at a lower temperature level.
  • the invention also relates to a motor vehicle, preferably a commercial vehicle, with a cooling device as described in this document.
  • the cooling device can be used for fuel, oil, charge air, engine and / or battery cooling.
  • the motor vehicle can comprise an internal combustion engine and / or electric motor and / or a fuel cell.
  • the invention also relates to a stationary system with a cooling device as described in this document.
  • the stationary system can also include an internal combustion engine and / or electric motor and / or a fuel cell.
  • FIG. 1 an exemplary embodiment of the claimed cooling device 100 is shown schematically.
  • This comprises two cooling circuits 10a, 10b, each of which has a ventilation line 1a, 1b and a filling line 2a, 2b with a, designed as a chamber, common expansion tank 3 for coolant are connected.
  • the two cooling circuits 10a and 10b have no further fluidic connection to one another.
  • the individual cooling circuits 10a and 10b shown here greatly reduced for the sake of clarity, each include a coolant cooler 5a, 5b, a coolant pump 8a, 8b and a heat exchanger 9a, 9b, these components being connected via corresponding pipes 11a, 11b.
  • the coolant pumps 8a, 8b pump coolant to the heat exchangers 9a, 9b, which are in contact with self-heating or externally heated components, for example an internal combustion engine.
  • the pipes 11a, 11b lead in a manner known per se past the components to be cooled, for example engine components, or are led through them (not shown).
  • heat exchangers 9a, 9b heat is transferred from these components to the coolant, which is then pumped on to the respective coolant coolers 5a, 5b, for example a downdraft cooler.
  • the coolant coolers 5a, 5b the heat stored in the coolant is finally given off to the ambient air.
  • the coolant then flows again to the respective coolant pumps 8a, 8b and the cycle begins again.
  • the cooling circuit 10a has a lower operating temperature T 1 than the cooling circuit 10b, as a result of which the coolant present in the expansion tank 3 will also have a mixed temperature between the operating temperatures of the two cooling circuits 10a and 10b. Because of this mixing of coolant in the expansion tank 3, coolant that is “too warm” would consequently be returned to the cooling circuit 10a with a lower temperature level via the filling line 2a.
  • an air-cooled heat exchanger 4 is provided in the area of the filling line 2a of the cooling circuit 10a with a lower temperature level.
  • This is designed as a first partial area 51 of a coolant cooler 5a, which is separated from a second partial area 52 of the coolant cooler 5a.
  • Both the first and the second sub-area 51, 52 have their own inlet 61, 62 and outlet 71, 72 for coolant.
  • FIG. 2 shows an embodiment of the air-cooled heat exchanger 4 for pre-cooling the filling line 2a as a first partial area 51 of a coolant cooler 5a.
  • the coolant cooler 5a known per se in the prior art, for example in the form of a downdraft cooler, is subdivided via a vertical partition 12 into two subregions 51 and 52 that are separated from one another, that is, are not fluidically connected within the coolant cooler 5a. Coolant flows through each of the two sub-areas 51 and 52, which enters the respective sub-area 51, 52 via the corresponding inlet 61, 62 and leaves the respective sub-area 51, 52 via the corresponding outlet 71, 72 without mixing in between of coolant of the two circuits can take place.
  • FIG 3 an embodiment (not according to the invention) is shown in which the air-cooled heat exchanger 4 is designed as a separate component 40 for pre-cooling the filling line 2a. It is therefore explicitly not part or sub-area 51 of a coolant cooler 5a.
  • a coolant cooler 5a In the cooling circuit 10a itself, however, there is a coolant cooler 5a, which, however, only serves to cool the coolant in the cooling circuit 10a, while the air-cooled heat exchanger 4 pre-cools the coolant in the filling line 2a before it enters the cooling circuit 10a.
