Abstract
A liquid-air cooling system () has at least one fan device () including at least one variable-speed fan motor () driving a fan impeller () to create a cooling power for a fluid () in a fluid cycle (). To regulate the speed of the fan motor () by a control and/or regulation device (), at least one actual value (Ta) downstream of a segmented heat exchanger () is compared to a predefined desired value (Tb). The control and/or regulation device () adjusts the cooling power according to the current power values of the respective machine unit ().
