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).

Abstract: A liquid-air cooling system (1) has at least one fan device (2) that consists of 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). In order to regulate the speed of the fan motor (3) by mains of a control and/or regulation device (24), at least one actual value (tist) downstream of the segmented heat exchanger (19) is compared to a predefined desired value (tsoll), and the control and/or regulation device (24) adjusts the cooling power according to the current power values of the respective machine unit (9).

Abstract: A fluid cooling device embodied as a modular unit includes a drive motor (10) driving a ventilation wheel (12) and a fluid pump (14) that supplies a first type of fluid into a fluid system, and leads to a heat exchanger (22) from which the fluid is redirected into the fluid system in a tempered manner. A second fluid pump (32) is used to extract a second type of fluid from the reservoir (30) and to supply the second type of fluid to a second fluid system, from which the second type of liquid is redirected towards the reservoir (30) in a guiding manner via the first heat exchanger (22) and the second heat exchanger (24). The second fluid pump enables different tempering operations to be carried out for separate fluid systems, using only one fluid cooling device.

Abstract: The invention relates to a fluid cooling device in the form of a modular unit comprising a drive motor (10) which drives a ventilation wheel (12) which can be rotated in a ventilation housing (28). At least one fluid can be conveyed from a feed reservoir (20) into a hydraulic working circuit which, when in an operational state, basically heats the fluid and from which the cooled fluid returns to the feed reservoir (20). Parts of the feed reservoir (20) at least partially surround the ventilation wheel (12) and form the ventilation housing (28) which is preferably made of a plastic material, whereupon the ventilation housing is embodied as part of the feed reservoir, enabling the volume of the tank to be increased and resulting in increased damping of the noise of the ventilation wheel.
