       6 . The arrangement as claimed in  claim 1 , wherein the air-regulating device is disposed behind the heat exchanger in the air flow direction. 
   
   
       7 . The arrangement as claimed in  claim 6 , wherein in that the air-regulating device is disposed in a frame. 
   
   
       8 . The arrangement as claimed in  claim 7 , wherein in the frame there is disposed a cooling-air blower. 
   
   
       9 . The arrangement as claimed in  claim 1 , wherein the air-regulating device is configured as a shutter. 
   
   
       10 . The arrangement as claimed in  claim 9 , wherein between the shutter and the cooling-air blower there is disposed a swivel flap, by which a partial air flow flowing through the heat exchanger can be shut off or separated. 
   
   
       11 . The arrangement as claimed in  claim 10 , wherein one of the heat exchangers is configured as a coolant cooler for cooling an internal combustion engine. 
   
   
       12 . The arrangement as claimed in  claim 10  wherein, one of the heat exchangers is configured as a charge-air cooler. 
   
   
       13 . An arrangement for cooling an internal combustion engine of a motor vehicle, in particular a cooling module, comprising
 an air-conducting device for air guidance,   at least one heat exchanger for cooling a fluid flow, and   an air-conveying device,   wherein the air-conducting device has a frame with variable intake cross section, which can be altered between a maximum (Amax) and a minimum (Amin), and the differential area between maximal and minimal intake cross section can be utilized at least partially as a ram air opening.   
   
   
       14 . The arrangement as claimed in  claim 13 , wherein the intake cross section can be altered in steps. 
   
   
       15 . The arrangement as claimed in  claim 13 , wherein the intake cross section can be altered steplessly. 
   
   
       16 . The arrangement as claimed in  claim 13 , wherein, the frame has at least one flap for adjusting the intake cross section. 
   
   
       17 . The arrangement as claimed in  claim 16 , wherein the at least one flap is disposed pivotably in the rear wall of the frame. 
   
   
       18 . The arrangement as claimed in  claim 17 , wherein the at least one flap is disposed in the outer regions of the frame rear wall. 
   
   
       19 . The arrangement as claimed in  claim 16 , wherein at least two flaps are provided, which can be pivoted independently of each other, in particular one after the other. 
   
   
       20 . The arrangement as claimed in  claim 16 , wherein the at least one flap is configured as a folding flap and is integrated in the rear wall of the frame. 
   
   
       21 . The arrangement as claimed in  claim 16 , wherein the air flow which can be sucked up by the fan behind the heat exchangers can be sealed off from the heat exchangers by the at least one flap. 
   
   
       22 . The arrangement as claimed in  claim 13 , wherein the frame has a foldable rear wall having a displaceable separating and sealing element, which delimits the intake cross section and seals off the suction flow.
