A transducer system includes a housing, an electromechanical transducer within the housing, a wicking material adjacent to a portion of the electromechanical transducer, and a coolant solution within the housing. The coolant solution transitions from a liquid phase to a gaseous phase in response to a temperature of the electromechanical transducer exceeding a threshold temperature. In some example cases, the coolant solution has a boiling point of less than about 60° C., which effectively defines the threshold temperature. The coolant solution may be chosen such that it remains a liquid during a first phase (cooling via conduction), and then evaporates during a second phase (cooling via conduction and convection) as the electromechanical transducer heats up.
