AI Technical Summary
Existing ultrasonic transducers are prone to performance degradation due to heat accumulation and mechanical vibration under high-frequency or high-power conditions. Traditional anti-vibration structures have insufficient heat dissipation, which affects the lifespan of piezoelectric ceramic crystals and makes the structure unstable.
The structure combines shock-absorbing and heat-dissipating elements, including a honeycomb silicone shock-absorbing layer, a high-strength rubber protective layer, a heat-dissipating copper pipe, a cooling fan, and a liquid heat-conducting medium. Through this multi-layer design, vibrations are absorbed and heat is actively dissipated, enhancing structural stability and heat dissipation efficiency.
It significantly improves the vibration suppression and heat dissipation performance of ultrasonic transducers, extends the service life of equipment, and ensures its reliability in complex environments.
