- a fluid in particular a liquid fluid
- heat can be transferred between the fluid and the air via the heat exchanger, for example in such a way that heat can be transferred from the fluid to the air via the heat exchanger.

- at least one component of the motor vehicle in particular provided in addition to the heat exchanger, can be cooled by means of the fluid.
- the component is or includes, for example, a drive machine for driving the motor vehicle.
- the air control system also comprises a preferably inherently rigid, i.e. dimensionally stable and thus preferably designed as a solid body, slat as the first slat, which, in particular relative to the base element, is movable between at least one closed position covering and thus closing at least a partial area of the air opening, thus blocking fluid, and at least one open position releasing at least the partial area of the air opening.

- a supply of the heat exchanger with a sufficient amount that is, with a sufficient volume and/or mass flow of air via the air opening, can be ensured so that particularly advantageous cooling of the fluid and thus of the component can be ensured.
- fins which are spaced apart from one another in the longitudinal direction of the fin, are provided as first fins on the fin.
- the fin extends elongatedly along its preferably straight longitudinal direction, i.e. along a straight line, so that, for example, the fin itself, i.e. considered on its own, has a larger dimension along its longitudinal direction, i.e. is longer than in other directions of extension of the fin that run perpendicular to one another and perpendicular to the longitudinal direction.
- the respective fin is to be understood as a respective body that is preferably inherently rigid and thus dimensionally stable and preferably designed as a solid body.
- the fins protrude from the fin in a direction that runs obliquely or preferably perpendicular to the longitudinal direction of the fin.
- the direction mentioned is one of the previously mentioned directions of extension.
- the fins protrude from the slat in the same direction, which runs obliquely or preferably perpendicular to the longitudinal direction of the slat. It is conceivable that the fins are formed separately from one another and separately from the slat and are connected to the slat.
- the slat and the fins are formed integrally with one another, i.e. are formed from a single piece, so that preferably the slat and the fins are formed by an integral body that is formed in one piece, thus formed from a single piece and thus integrally manufactured, so that preferably the slat and the fins are designed as a monoblock or are formed by a monoblock.
- the slat and the fins are made from a plastic.
- the lamella and the fins are produced by injection molding, in particular by Plastic injection molding.
- the lamella is not elastically deformable, and preferably the respective fin is not elastically deformable.
- the fins are arranged in overlap with respective parts of the air opening that adjoin the slat in the open position, in particular such that in the open position of the slat the fins protrude into the air opening, and thus into the respective parts of the air opening. Since the fins are provided on the slat, the fins can be moved with the slat, in particular relative to the base element between the open position and the closed position. The slat and thus the fins can be pivoted about a first pivot axis, in particular relative to the base element, between the open position and the closed position.
- the first pivot axis runs in the transverse direction of the motor vehicle, and thus runs parallel to the transverse direction of the motor vehicle, the transverse direction of the vehicle also being referred to as the y-direction or as y.
- the first pivot axis coincides with the longitudinal direction of the slat. Since the fins are spaced apart from one another in the longitudinal direction of the slat, air can flow between the fins when the slat is open and thus through the air opening. In other words, the fins allow air to flow through the air opening when the slat is open because the fins are arranged in overlapping relation with the parts of the air opening, but in
- the fins when the slat is in the open position, the fins form a net, a net structure, a grid or a grid structure because the fins protrude from the slat and are spaced apart from one another, so that, for example, by means of the fins, dirt such as leaves which moves towards the air opening during the aforementioned journey, for example, can be caught and held back and thus prevented from flowing through the air opening and reaching the heat exchanger.
- the fins form a grid in the open position of the slat, also known as a protective or dirt grid, by means of which dirt or other objects can be prevented from entering the air opening and reach the heat exchanger.
- the air control system can therefore not only be used to regulate the air flow through the air opening, but also to prevent dirt and other objects from penetrating the air opening and reaching the heat exchanger, so that a particularly wide range of functions of the air control system can be achieved in a particularly simple manner.
- the parts of the air opening are also referred to as the first parts. When the parts are mentioned above and below, this means the first parts of the air opening, unless otherwise stated.
- the air opening is arranged, for example, in a front bumper of the motor vehicle.
- the invention makes it possible, for example, to avoid an additional, separate grille in the bumper, so that a great deal of design freedom can be created.
- the use of an additional, separate grille, which is thus designed as an additional part, before or after the air control system or the air opening can be avoided, so that the number of parts and thus the costs and weight of the motor vehicle can be kept particularly low.
- the fins are spaced apart from one another in the longitudinal direction of the slat, excessive blocking of the air opening can be avoided when the slat is in the open position.
- the respective fin has only a very small, i.e. small, cross-section, a large area of the air opening can be released when the slat is in the open position, so that the heat exchanger can be supplied with a sufficient amount of air.
- the slat is used as a base support for the said grille, so that the grille can be produced in a way that is space-saving, lightweight and cost-effective.
- the invention provides that the air control system has a second slat, which is preferably inherently rigid and thus preferably designed as a solid body and is provided in addition to the slat, which can be pivoted about a second pivot axis spaced from the first pivot axis between at least one second closed position covering and thereby closing at least a second partial area of the air opening, thus blocking it fluidically, and at least one second open position releasing at least the second partial area of the air opening, in particular relative to the base element.
- the pivot axes run parallel to one another, with the pivot axes being spaced from one another.
- second fins are provided on the second lamella, which are spaced apart from one another in the longitudinal direction of the second lamella, are preferably inherently rigid and/or preferably designed as solid bodies, and protrude from the second lamella in a second direction that runs obliquely or perpendicularly to the longitudinal direction of the second lamella.
- the longitudinal direction of the second lamella is also referred to as the second longitudinal direction.
- the longitudinal directions run parallel to one another, with the longitudinal directions being spaced apart from one another.
- the second fins are arranged in overlap with respective second parts of the air opening that adjoin the second lamella in the second open position.

- the second parts are arranged in pairs, in particular next to each other and next to the first parts.
- the first parts are arranged next to each other in pairs.

This allows the air flow to be adjusted particularly advantageously and dirt such as leaves can be particularly well retained and caught, thus preventing it from penetrating the air opening.
- the invention provides that in the open positions of the slats the second fins are arranged offset from the first fins in the longitudinal direction of the respective slat.
- first fins protrude from the first slat towards the second slat, so that in the first open position the first direction points from the first slat towards the second slat.
- second fins protrude from the second slat towards the first slat, so that in the second open position the second direction runs from the second slat behind the first slat.
- the slats are arranged at a distance from one another that runs perpendicular to the respective longitudinal direction of the respective slat. The distance thus runs in the first direction or in the second direction.
- the respective first fin which in the first open position protrudes from the first slat to the second slat and thus in the first direction, has a respective first outer dimension that runs perpendicular to the respective longitudinal direction of the respective slat and from the first slat to the second slat and thus in the first direction, which is also referred to as the first height.
- the respective second fin which in the second open position protrudes from the second slat to the first slat and thus in the second direction, has a respective second outer dimension that runs perpendicular to the respective longitudinal direction of the respective slat and from the second slat to the first slat and thus in the second direction, which is also referred to as the second height.
- the respective first fin has a respective first free end opposite the first lamella, at which the respective first fin ends.
- the respective second fin has a respective second free end opposite the second lamella, at which the respective second fin ends.
- the respective first fin extends from the first lamella in the first direction continuously to the respective first free end. Furthermore, for example, in the second open position of the second lamella, the respective second fin extends from the second lamella in the second direction continuously to the respective second free end.
- first outer dimension and the second outer dimension in total are greater than 50%, in particular greater than 60% and most particularly greater than 70% of the distance.
- first height and the second height in total form a total height which is greater than 50%, in particular greater than 60% and most particularly greater than 70% of the distance.
- the total height is most preferably greater than 80%, in particular greater than 90%, most particularly greater than 95% and most preferably greater than 98% of the distance.
- this allows dirt such as leaves to be effectively and efficiently retained and prevented from penetrating the air opening.
- the fins are in the open position, an advantageous supply of the heat exchanger with a sufficient amount of air via the air opening can be ensured.
- the respective fin extends in a respective plane which runs perpendicular to the longitudinal direction of the lamella. This ensures an advantageous spacing of the fins along the longitudinal direction of the lamella, so that in the open position a supply of the heat exchanger with a sufficiently large amount of air can be ensured. On the other hand, dirt can be advantageously caught and retained by means of the fins and the lamella.
- a further embodiment is characterized in that, in the installation position of the air control system, the longitudinal extension direction of the slat runs in the transverse direction of the vehicle. This allows the air flow to be advantageously adjusted and the fins can form the grille particularly advantageously in conjunction with the slats, so that dirt can be retained particularly well.
- the respective fin protrudes upwards or downwards from the slat in the vertical direction of the vehicle. This allows the fins and the slat to form the grille in a particularly advantageous manner, namely in the open position, whereby dirt can be retained particularly well.
