Abstract

A pulsating fluid cooling device comprising a transducer (1) for generating a pulsating fluid flow and a fluid guiding structure (3) for directing the pulsating flow towards an object (4) to be cooled. The device further comprises a sensor (7) for detecting at least one variable external to the transducer, a feedback path (6) for providing a feedback signal 5 indicative of this variable, and control circuitry (5) arranged to receive the feedback signal and generate a frequency control signal based on said feedback, for controlling a working frequency o f the transducer. By providing the control circuitry wit h informat ion about the conditions at the object, the frequency can be controlled based on actual performance. The performance can be 10 optimized in terms of the measured variable. For example, if the feedback signal includes informat ion about the temperature change of the object, the control circuitry can be arranged to select a working frequency that results in optimal cooling.
