Abstract

The invention discloses a pulsating heat pipe heat dissipating type high-power ultrasonic transducer and relates to the technical field of ultrasonic transducers. The pulsating heat pipe heat dissipating type high-power ultrasonic transducer comprises a piezoelectric ultrasonic transducer and a pulsating heat pipe heat dissipating device. The piezoelectric ultrasonic transducer comprises a stressbolt, a rear cover plate, piezoelectric ceramic elements and a front cover plate, wherein a series of holes are formed along the radial direction of the front cover plate. The rear cover plate is cylindrical, and the front cover plate is conical. The front cover plate, the piezoelectric ceramic elements and the rear cover plate are closely connected through the stress bolt. The pulsating heat pipeheat dissipating device is organically coupled inside the piezoelectric ultrasonic transducer. On the premise that the performance of the transducer is not influenced, based on the mechanical structure of a traditional piezoelectric ultrasonic transducer, the pulsating heat pipe heat dissipating type high-power ultrasonic transducer is formed through organic coupling with pulsating heat pipes. The efficient heat-transferring characteristic of the pulsating heat pipes is utilized to take away heat generated inside the high-power piezoelectric ultrasonic transducer when the high-power piezoelectric ultrasonic transducer works; it is guaranteed that the transducer runs efficiently and safely within a normal-temperature range; and in addition, the service life of the piezoelectric ultrasonictransducer can be prolonged.

Description

technical field [0001] The invention relates to the technical field of ultrasonic transducers, in particular to a pulsating heat pipe cooling type high-power ultrasonic transducer. Background technique [0002] In the application of power ultrasonic technology, the stability of the working performance of the transducer is very important and has always been highly valued by the industry. The piezoelectric ultrasonic transducer is the core device for energy conversion in the ultrasonic vibration system, and the temperature has a significant impact on its performance. Due to the power loss caused by the impedance mismatch between the transducer and the power supply under high-power working conditions and the dielectric loss of the piezoelectric ceramic itself, heat is generated, and because the piezoelectric ceramic is an insulating material, its thermal conductivity is poor. The temperature rise in the center of the piezoelectric ultrasonic transducer is serious. If the tempe...
