Description

[0001] The present invention relates to a cooling system for a motor vehicle. The invention also relates to a motor vehicle equipped with such a cooling system.

[0002] Motor vehicles with a driver's cab, such as trucks and tractors, can have a comparatively high cooling requirement, as such vehicles are often equipped with multiple, powerful units that generate a comparatively large amount of waste heat during operation. Cooling circuits and refrigeration circuits, in which a coolant or refrigerant circulates, are used to cool such units. The circuits absorb the heat from the units via the coolant or refrigerant and transport the heat to a radiator, which dissipates the heat to the vehicle's surroundings. For this purpose, an airflow can flow through the respective radiator, which absorbs the heat and dissipates it to the environment. Depending on the unit, such an airflow must also be maintained when the vehicle is stationary. Accordingly, fans are used to generate the airflow.For vehicles with multiple components that require cooling, a cooling system can be used for a correspondingly large number of cooling or refrigeration circuits. This system accordingly has several coolers, each with a separate fan. The effort required to implement such a cooling system with multiple coolers and multiple fans is correspondingly high. The separate fans also require a comparatively large amount of installation space. Furthermore, the fans generate a high level of noise during operation, with the associated noise being audible in the vehicle's surroundings and in the driver's cab and generally perceived as disturbing.

[0003] The present invention addresses the problem of providing an improved or at least a different embodiment for a cooling system or for a motor vehicle equipped therewith, which is characterized in particular by reduced manufacturing costs and / or reduced installation space requirements. Furthermore, a reduction in noise emissions is sought.

[0004] This problem is solved according to the invention by the subject matter of the independent claim. Advantageous embodiments are the subject matter of the dependent claims.

[0005] The invention is based on the general idea of ​​combining several coolers in at least one cooling tower, in which the coolers are arranged one above the other with respect to the vehicle height. The coolers are configured so that they can be passed through by an air flow on the outside and by a coolant or refrigerant on the inside. The air flow generated by a fan is distributed among the coolers of the respective cooling tower so that the air flow flows through them in parallel. The crucial point here is that each cooling tower is assigned exactly one fan, which generates the air flow that flows through the coolers of the cooling tower in parallel. The multiple fans of each cooling tower are therefore assigned a common fan. This significantly reduces the required number of fans, which correspondingly reduces the installation space required and manufacturing costs.At the same time, this also results in a significant reduction in noise.

[0006] In the present context, a ‘configuration’ is synonymous with a ‘design’ and / or ‘arrangement’, so that the phrase ‘configured so that’ is synonymous with the phrase ‘designed and / or arranged so that’.

[0007] Specifically, the invention proposes a cooling system for a motor vehicle, comprising at least one cooling tower having at least two radiators for cooling a coolant and / or a refrigerant by means of an air flow, and at least one fan for driving the air flow. Each cooling tower further comprises at least one duct for guiding the air flow between the fan and the radiators. The radiators are arranged one above the other in the respective cooling tower in a vehicle vertical direction, with the air flow flowing through them on the outside and the coolant and / or refrigerant flowing through them on the inside, and are also connected to the duct such that the air flow flows through the radiators in parallel during operation of the cooling system.

[0008] The coolers of the respective cooling tower can be flowed through by a coolant and / or refrigerant because, in the case of two or more coolers in the respective cooling tower, at least one cooler can be connected to a cooling circuit in which a coolant circulates, while in addition at least one of the coolers can be connected to a refrigeration circuit in which a refrigerant circulates.

[0009] According to an advantageous embodiment, the cooling system can have at least two cooling towers, each having a plurality of coolers and a channel.

[0010] According to a first alternative embodiment, the fan can be jointly assigned to both cooling towers and generate the airflow for both cooling towers, which flows through the coolers of the respective cooling tower in parallel. In this case, the cooling system can have a connecting duct that is fluidly connected to the ducts of the two cooling towers, so that the airflow generated by the shared fan is distributed between the two cooling towers in the distribution duct, so that in both cooling towers, the coolers of the respective duct are flowed through in parallel by the airflow. Thus, the cooling system for two cooling towers can operate with a single fan, with at least four coolers being flowed through in parallel by the airflow. This first alternative is extremely compact and particularly quiet in operation.

[0011] According to a second alternative embodiment, the cooling system can have a separate fan for each cooling tower, which generates the airflow for the respective cooling tower, which flows through the coolers of the respective cooling tower in parallel. With two cooling towers, two fans are then required. This allows the cooling system to be implemented more compactly overall, allowing the use of a large number of identical or symmetrical components, thus reducing costs.

[0012] According to an advantageous embodiment, the respective fan can be arranged in a suction-type configuration, so that it is located downstream of the radiator with respect to the air flow. Alternatively, the respective fan can be arranged in a push-type configuration, so that it is located upstream of the radiator with respect to the air flow. Depending on the arrangement of the cooling system on the vehicle, a suction-type or push-type configuration can be advantageous. A push-type configuration of the fan is preferred for cooling towers.

[0013] In another advantageous embodiment, the respective duct can have a flow-through cross-section that varies in the direction of the air flow, such that the flow-through cross-section increases from the cooler furthest from the fan to the fan. In this way, the volume flow of the air flow can be homogenized across the coolers of the respective cooling tower, so that each cooler of the respective cooling tower is permeated with a sufficiently large air flow.

[0014] In another advantageous embodiment, it can be provided that at least one of the coolers of the respective cooling tower is configured as a low-temperature cooler, while at least one of the coolers of the respective cooling tower is configured as a high-temperature cooler. In a low-temperature cooler, the coolant or refrigerant to be cooled has a temperature of less than 100°C at the inlet of the cooler. In a high-temperature cooler, the coolant or refrigerant to be cooled has a temperature of more than 100°C at the inlet of the cooler. An embodiment is preferred here in which the low-temperature cooler is arranged closer to the fan than the high-temperature cooler. In this way, more cooling air is generally available to the low-temperature cooler than to the high-temperature cooler, which requires a lower volume flow due to the higher temperature difference.

[0015] In an advantageous embodiment, the cooling system can be configured such that the air flow is deflected twice by approximately 90° from an air inlet to an air outlet. In particular, it can be provided that the two 90° deflections occur around two deflection axes that run essentially perpendicular to each other. The double deflection of the air flow allows for a particularly compact design for the cooling system and thus space-saving installation on the vehicle.

[0016] For example, the air inlet can be configured and / or arranged such that the air flow flows through the air inlet approximately parallel to a longitudinal direction of the vehicle. The duct can then also be shaped such that it deflects the air flow in the region of the fan by approximately 90°, so that the air flow from the fan to the radiators flows approximately parallel to the vehicle's vertical direction. Furthermore, the radiators can now be configured and / or arranged such that they deflect the air flow by approximately 90°, so that the air flow flows through the fans and the air outlet approximately parallel to a transverse direction of the vehicle. This makes the cooling system particularly suitable for attachment to a driver's cab, such that the respective cooling tower extends along a rear side of the driver's cab and along a side of the vehicle.

[0017] The respective fan can generally be configured as an axial fan. However, a particularly advantageous embodiment is one in which the respective fan is configured as a radial fan. Such a radial fan is characterized by relatively high performance despite a comparatively small diameter, while also exhibiting comparatively low noise levels.

[0018] A motor vehicle according to the invention has a driver's cab that has two vehicle sides facing away from each other in a transverse direction of the vehicle, a front side and a rear side facing away from the front side in a longitudinal direction of the vehicle. The vehicle is also equipped with a cooling system of the type described above. The cooling tower can be arranged at the rear of the driver's cab on one of the vehicle sides. The fan can expediently be arranged on or in a roof of the driver's cab. This results in a particularly compact and space-saving installation of the cooling system on the vehicle or on the driver's cab.

[0019] In an advantageous embodiment, an inlet duct can be formed on or in the roof, which guides the air flow to the fan and which has an air inlet at the front of the driver's cab through which the air flow flows into the cooling system. Furthermore, an air outlet can be formed on the respective side of the vehicle, through which the air flow flows out of the cooling system. The coolers of the respective cooling tower can then be arranged at the air outlet on the respective side of the vehicle, such that the air flow flowing through the coolers flows immediately afterwards through the air outlet. This results in a particularly compact design for the cooling system on the vehicle.

[0020] In another advantageous embodiment, the driver's cab can have a side door on each side of the vehicle and a side panel that connects to the rear of the side door and has an inner side facing the other side of the vehicle. The respective cooling tower can then be arranged on the inner side of the side panel of the respective side of the vehicle. This gives the side panel an additional function, namely as a support for the respective cooling tower. The main function of the side panel is to create an aerodynamically favorable transition between the driver's cab and a trailer or a payload body of the vehicle.

[0021] According to an advantageous embodiment, the respective air outlet can be integrated into the respective side panel. The air outlet can have a louvre structure, for example, to deflect the air flow downward.

[0022] In the present context, the relative location specifications “front”, “rear”, “top” and “bottom” refer to the installation situation in the vehicle, where “front” is facing the front of the vehicle, “rear” is facing the rear of the vehicle, “bottom” is facing the ground on which the vehicle is standing or driving, and “top” is facing away from the ground.

[0023] The motor vehicle can be configured as a truck and / or a tractor. Additionally or alternatively, the motor vehicle can be configured as an electrically powered motor vehicle. Such an electrically powered motor vehicle can have an electric drive and a battery or a fuel cell to supply the electric drive with electrical energy. The motor vehicle can therefore be a battery vehicle or a fuel cell vehicle.

[0024] The coolers of the respective cooling tower can serve as auxiliary coolers for additional heat sources in the vehicle. Such additional heat sources are typically auxiliary units, such as an air conditioning cooler or a cooler for lubricants or hydraulic fluids. The coolers of the respective cooling tower can be provided on the vehicle in addition to a main cooler, which serves to cool the vehicle's main heat sources. Such main heat sources are the vehicle's main units, such as a vehicle drive. Other main units in the vehicle can be a vehicle battery or a fuel cell.

[0025] Further important features and advantages of the invention emerge from the subclaims, from the drawings and from the associated description of the figures with reference to the drawings.

[0026] It is understood that the features mentioned above and those to be explained below can be used not only in the respective combination specified, but also in other combinations or on their own, without departing from the scope of the invention as defined by the claims. Components mentioned above and to be mentioned below of a higher-level unit, such as a device, an apparatus, or an arrangement, which are designated separately, may form separate parts or components of this unit or be integral areas or sections of this unit, even if this is shown differently in the drawings.

[0027] Preferred embodiments of the invention are illustrated in the drawings and are explained in more detail in the following description, wherein the same reference numerals refer to the same or similar or functionally identical components.

[0028] They show, schematically, Fig. 1 a highly simplified side view of a motor vehicle with a cooling system, Fig. 2 a view from the rear of the vehicle in the area of ​​the cooling system, Fig. 3 a view as in Fig. 2, but with a different embodiment.

[0029] Accordingly Fig. 1 comprises a motor vehicle 1, which is indicated here purely as an example as a tractor, a driver's cab 2 and a cooling system 3. The vehicle 1 defines in the usual way a vehicle longitudinal direction X, a vehicle transverse direction Y and a vehicle height direction Z, which run perpendicular to each other. Fig. 1 to 3, the vehicle height direction Z extends vertically. In Fig. 1, the vehicle's longitudinal direction X extends horizontally, while the vehicle's transverse direction Y is perpendicular to the plane of the drawing. Fig. 2 and Fig. 3 the vehicle transverse direction Y extends horizontally, while the vehicle longitudinal direction X is perpendicular to the plane of the drawing.

[0030] The driver's cab 2 has two vehicle sides 4 and 5, which face away from each other in the vehicle transverse direction Y. In Fig. 1 only the first or left side of the vehicle 4 facing the viewer is visible. In the Fig. 2 and Fig. 3, however, the other or second or right vehicle side 5 is also visible. The driver's cab 2 further has a front side 6 and a rear side 7, which face away from each other in the vehicle's longitudinal direction X. In the Fig. 2 and Fig. 3, the rear side 7 of the driver's cab 2 is facing the viewer.

[0031] The vehicle 1 has a main cooler 8, which is integrated into a main cooling circuit 9 for cooling at least one main unit 10. A main fan 11 for generating a cooling air flow 12, which is arranged here purely as an example, in a suction-type configuration, can be assigned to the main cooler 8. The main unit 10 can be, for example, a vehicle drive, a vehicle battery, or a fuel cell and forms a main heat source.

[0032] The cooling system 3 has at least one cooling tower 13, which has at least two coolers 14, 15, which serve to cool a coolant or a refrigerant by means of an air flow 16. In the example of the Fig. 1, one cooler 14 is integrated into a first auxiliary cooling circuit 17, which serves to cool a first auxiliary unit 18. The other cooler 15 is integrated into a second auxiliary cooling circuit 9, 10, which serves to cool a second auxiliary unit 20. One of the two auxiliary cooling circuits 17, 19 can be operated with a coolant, while the other cooling circuit 17, 19 can be operated with a refrigerant and can accordingly also be referred to as a refrigeration circuit 17, 19.

[0033] The cooling system 3 has at least one fan 21 for driving the air flow 16. The respective cooling tower 3 has at least one duct 22 for guiding the air flow 16 between the fan 21 and the coolers 14, 15. The coolers 14, 15 are arranged one above the other in the respective cooling tower 13 in the vehicle height direction Z. The air flow 16 flows through the coolers 14, 15 on the outside, while the coolant or refrigerant flows through them on the inside. Furthermore, the coolers 14, 15 in the respective cooling tower 13 are connected to the duct 22 such that the air flow 16 flows through the coolers 14, 15 in parallel.

[0034] In the examples shown here, the respective cooling tower 13 has exactly two coolers 14, 15. It is clear that the respective cooling tower 13 can also have three or more coolers 14, 15 in another embodiment.

[0035] How the Fig. 2 and Fig. 3, the cooling system 3 can have two such cooling towers 13, each having a plurality of coolers 14, 15 and a channel 22. In the case of the Fig. 3, the two cooling towers 13 are assigned a single fan 21 or a common fan 21, which generates the air flow 16 for both cooling towers 13, which flows through the coolers 14, 15 of the respective cooling tower 13. In the example of Fig. 3, the cooling system 3 has a connecting duct 23 that is fluidically connected to the ducts 22 of the two cooling towers 13. The connecting duct 23 is connected to the two ducts 22 in such a way that the air flow 16 generated by the common fan 21 is divided in the distribution duct 23 between the two ducts 22 of the two cooling towers 13, forming two parallel air flows 16 that flow in parallel through the coolers 14, 15 of the respective cooling tower 13.

[0036] However, preference is given to Fig. 2, in which the cooling system 3 has a fan 21 of this type for each cooling tower 13, which fan generates the air flow 16 for the respective cooling tower 13, which flows through the coolers 14, 15 in parallel within the respective cooling tower 13. While Fig. 3 shows a single common fan 21, in Fig. 2, two separate fans 21 are provided. In the examples shown here, the respective fan 21 is arranged in a pushing manner, so that it is located upstream of the coolers 14, 15 with respect to the air flow 16. The respective duct 22 then guides the air flow 16 from the fan 21 to the coolers 14, 15. In principle, however, a suction arrangement of the fan 21 is also possible. In particular, with the same arrangement of the components, the flow direction of the air flow 16 can then be reversed. With the same flow direction of the air flow 16, the respective fan 21 can be arranged between the coolers 14, 15 and the respective side wall 4, 5. The respective duct 22 then guides the air flow 16 from the coolers 14, 15 to the fan 21.

[0037] An embodiment with three or more cooling towers 13 is also conceivable, in which case a common fan 21 can be assigned to all cooling towers 13, or a separate fan 21 can be assigned to each cooling tower 13, or a common fan 21 can be assigned to at least two cooling towers 13.

[0038] The respective channel 22 can have a flow-through cross-section 24 which varies in the flow direction of the air flow 16, such that the flow-through cross-section 24 increases from the cooler 16 which is furthest away from the fan 21 to the fan 21. In the examples of Fig. 2 and Fig. 3, the flowable cross-section decreases in the direction of flow of the air flow 16 when the fan 21 is arranged in a pushing manner.

[0039] In another embodiment, one cooler 14 of the respective cooling tower 13 can be configured as a high-temperature cooler 14. The first cooling circuit 17 can in this case be configured as a high-temperature cooling circuit. The other cooler 15, however, can be configured as a low-temperature cooler 15. The second cooling circuit 19 can then be configured as a low-temperature cooling circuit. In the example shown here, the low-temperature cooler 15 is arranged closer to the fan 21 than the high-temperature cooler 14.

[0040] The cooling system 3 shown here is configured so that the air flow 16 is supplied from an air inlet 25, which is Fig. 1 can be seen, up to an air outlet 26, which is in the Fig. 2 and Fig. 3, is deflected twice by approximately 90°. The two deflections occur around axes running perpendicular to each other, resulting in a complex flow pattern for the air stream within the cooling system 3. According to Fig. 1, the air inlet 25 is configured or arranged such that the air flow 16 flows through the air inlet 25 approximately parallel to the vehicle longitudinal direction X. The channel 22 is now shaped such that it deflects the air flow 16 in the area of ​​the fan 21 by approximately 90°, so that the air flow 16 flows from the fan 21 to the coolers 14, 15 approximately parallel to the vehicle height direction Z. The vertical flow direction is in the Fig. 1 to 3. This first deflection takes place around a first deflection axis, which extends essentially parallel to the vehicle transverse direction Y. Furthermore, the coolers 14, 15 are now configured or arranged such that they deflect the air flow 16 again by approximately 90°, such that the air flow 16 flows through the fans 14, 15 and the air outlet 26 approximately parallel to the vehicle transverse direction Y. This horizontal flow direction of the air flow 16 is in the Fig. 2 and Fig. 3. This second deflection takes place around a second deflection axis, which extends essentially parallel to the vehicle's longitudinal direction X.

[0041] An embodiment is preferred in which the fan 21 is configured as a radial fan that sucks in the air axially and pushes it away radially.

[0042] Accordingly Fig. 1, the driver's cab 2 has a roof 27 on or in which an inlet duct 28 can be formed, which guides the air flow 16 to the fan 21 and which has the air inlet 25 on the front 6 of the driver's cab 2. The respective air outlet 26 is arranged on the respective vehicle side 4, 5 on which the respective cooling tower 13 is located. The coolers 14, 15 are also located on this vehicle side 4, 5 and are arranged such that the air flow 16 flowing through the coolers 14, 15 immediately afterwards flows through the air outlet 26.

[0043] The driver's cab 1 can be Fig. 1 on the respective vehicle side 4, 5 in the usual way have a side door 29 and a side panel 30, which adjoins the side door 29 at the rear and which according to the Fig. 2 and Fig. 3 has an inner side 31 facing the other vehicle side 4, 5. The respective cooling tower 13 is arranged on the inner side 31 of the side panel 30 of the respective vehicle side 4, 5. Furthermore, the respective air outlet 26 is integrated into the respective side panel 30.
