Embodiment Construction

[0022] figure 1 A liquid-air cooling system designated as a whole with the reference number 1 is shown in perspective and partially exploded view for supplying the schematically shown machine unit 9 or a component 11 of the machine unit 9 provided with a temperature-controlling fluid Fluid5. The liquid-air cooling system 1 comprises a fan arrangement 2 having a fan motor 3 designed as an electric motor 12 which drives a fan impeller 4 in the form of an axial blower with individual fan blades. The fan wheel 4 is accommodated as assigned in the fan wheel housing 22 and in the guard rail 17 . Fan wheel housing 22 may be made of plastic or sheet metal. figure 2 also shows figure 1 In the top view of the liquid-air cooling system in , a protective fence 18 is set in the area behind the fan impeller 4 for safety reasons. A heat exchanger 19 in the form of a finned radiator is arranged on the side of the fan wheel 4 opposite the guard rail 18 . The heat exchanger 19 extends ove...

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 means 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).

Description

technical field [0001] The invention relates to a liquid-air cooling system with at least one fan arrangement comprising at least one rotationally adjustable fan motor which drives a fan impeller in order to generate cooling power for a fluid of a fluid circuit, In this case, at least one actual value originating from a machine unit which can be connected to the liquid-air cooling system via a cooling circuit is compared with a specified value in order to adjust the rotational speed of the fan motor by means of the control and / or regulating device, so that according to the corresponding The current power value of the machine unit adjusts the cooling power of the liquid-air cooling system. Background technique [0002] EP0968371B1 shows and describes a fluid cooling device comprising an electric motor which drives a fan impeller and a fluid pump which draws fluid from an oil tank and feeds it into a hydraulic working circuit. In this hydraulic working circuit, the fluid (hyd...
