Abstract: A transducer system comprising a housing, an electromechanical transducer within the housing, a wicking material adjacent to a portion of the electromechanical transducer, and a multi-phase coolant solution within the housing. The multi-phase coolant solution transitions from a first phase to a second phase in response to a temperature of the electromechanical transducer exceeding a threshold temperature. In some example cases, the multi-phase coolant solution has a boiling point of less than about 60° C., which effectively defines the threshold temperature. The multi-phase 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.
