Abstract

Die vorliegende Erfindung bezieht sich auf eine Kühlereinrichtung (1) mit einem mit einem Kühlmittel beaufschlagbaren Kühler und einem ersten Gebläse (2, 4), das mittels einer Steuerung mit veränderbarer Luftförderleistung betreibbar ist.The present invention relates to a radiator (1) having a radiator to be acted upon by a coolant and a first blower (2, 4) operable by means of a variable air flow control.

Um eine Kühlereinrichtung zu schaffen, die eine wahlweise erhöhte Kühlleistung ermöglicht, wird vorgeschlagen, dass die Kühleinrichtung ein zweites Gebläse (2, 4) aufweist und auch das zweite Gebläse (2, 4) mittels der Steuerung mit veränderbarer Luftförderleistung betreibbar ist, von der Steuerung in einem Normalbetriebsmodus mittels einer geeigneten Sensorik zumindest eine oder mehrere Kenngrößen überwachbar, die ermittelten Sensorwerte von der Steuerung mit Vergleichswerten vergleichbar sind, und bei festgestellter Über- und/oder Unterschreitung eines der Steuerung vorgegebenen Schwellwertes oder dem Vorliegen eines Stellsignals von der Steuerung ein erster Sonderbetriebsmodus aktivierbar ist, in dem die Luftförderleistung eines oder beider Gebläse (2, 4) von der Steuerung veränderbar ist.

Figure imgaf001
In order to provide a cooler device which allows an optionally increased cooling capacity, it is proposed that the cooling device has a second blower (2, 4) and also the second blower (2, 4) is operable by means of the variable air flow control by the controller in a normal operating mode by means of suitable sensors, at least one or more parameters can be monitored, the determined sensor values from the controller can be compared to comparative values, and if the overshoot and / or undershooting of a threshold value specified for the control or the presence of an actuating signal from the controller is a first special operating mode can be activated, in which the air flow rate of one or both blower (2, 4) is variable by the controller.
