Thermal Wick Cooling for Vibroacoustic Transducers

Abstract

A soft thermally-conductive wick is provided to be connected between the metallic components on a transducer and onto a thermal sink. Beryllia ceramic is provided to improve heat flux within the transducer while maintaining electrical insulation. The wick provides adequate heat flux and such that the mass and stiffness of the wick do not adversely affect the vibroacoustic properties of the transducer in the frequency band of interest. The mass of the wick attachment is considered in the transducer design with the location and direction of the wick attachment designed so as to not introduce rocking modes or other adverse affects in the frequency band of interest. The wick may be strung, coiled, folded or configured in many ways between the transducer and the thermal sink to ensure that no acoustic or vibrational energy is transmitted down the length of the wick.
