Ultrasonic transducer with cooling device

Abstract

The invention discloses an ultrasonic transducer with a cooling device. The ultrasonic transducer is provided a blower fan and air inlet and outlet ducts, the air ducts extend to position near an oscillator piezoelectric ceramics crystal pile of the transducer, the blower fan generates high speed airflow, the air inlet and output ducts form high-speed convection near the piezoelectric ceramics, heat generated during work of the energy transducer is taken away, and cooling is efficient and rapid; and ports of the blower fan and air inlet and outlet ducts are provided with dustproof filtering screens and drying boxes to realize waterproof and dustproof effects, and long-term operation of the cooling device is ensured. The energy transducer is simple and reasonable in structure, low in the production cost, convenient to install and complete in functions, high-efficiency cooling of the energy transducer can be realized needless of an outside air source, and it is ensured that the energy transducer can work stably for long time under a high power condition.

Description

technical field [0001] The invention relates to the technical field of ultrasonic transducers, in particular to an ultrasonic transducer with a cooling device. Background technique [0002] Because ultrasonic waves will produce many physical, chemical and biological effects when propagating in media, ultrasonics is widely used in industry, agriculture, biomedicine and other fields. Ultrasonic applications generally use ultrasonic transducers to convert alternating electrical energy into ultrasonic vibrations within the ultrasonic frequency range to achieve energy conversion. Due to the certain consumption of the ultrasonic transducer during the energy conversion process, the specific performance is that the transducer vibrator will generate heat, especially under long-term high-power working conditions, which directly affects the performance of the transducer and even causes damage. Therefore, the heat dissipation of the transducer must be considered in high-power ultrasoni...

AI Technical Summary

Problems solved by technology

At present, the general practice is to use compressed air for cooling, and directly connect the compressed air to the transducer shell, which can better solve the problem of transducer cooling, but this method has higher requirements for compressed air, and it needs to be dry and clean. Air source, it is inconvenient to use in the case of no air source

In addition, there is also a transducer design using a liquid cooling system, but this method has a complex structure, difficult processing, and is expensive, making it difficult to mass-produce and use.
