Abstract
A liquid-air cooling system (1) has at least one fan device (2) including at least one variable-speed fan motor (3) driving a fan impeller (4) to create a cooling power for a fluid (5) in a fluid cycle (6). To regulate the speed of the fan motor (3) by a control and/or regulation device (24), at least one actual value (Ta) downstream of a segmented heat exchanger (19) is compared to a predefined desired value (Tb). The control and/or regulation device (24) adjusts the cooling power according to the current power values of the respective machine unit (9).
