Problems solved by technology

However, this method also has the following defects: the coolant used is water, ethanol, propanol, ethylene glycol, glycerin and other coolants, the acoustic impedance of the coolant is small, and part of the sound energy is consumed in the coolant in the form of heat ;As the temperature of the coolant chamber rises, it is easy to cause coolant leakage. It is necessary to regularly check whether the coolant leaks, which increases the workload of production operators; Long-period stable operation of industrial ultrasonic transducers
[0005] The existing cooling methods of ultrasonic transducers limit the industrial application and development of ultrasonic transducers to a certain extent

Abstract

The invention relates to the technical field of ultrasonic transducers, in particular to a cooling device and method for a fin type industrial magnetostrictive type ultrasonic transducer. The coolingdevice for the fin type industrial magnetostrictive type ultrasonic transducer comprises a transducer cavity, a wiring cavity, a coil winding, a magnetostrictive material and a vibrator block, whereinthe coil winding and the magnetostrictive material are integrally positioned inside the transducer cavity and the vibrator block is partially positioned in the transducer cavity; a transducer cavityhousing of the transducer cavity is a cylindrical structure with fins; one end of the cylindrical cavity is equipped with the vibrator block, and the other end of the cylindrical cavity is equipped with an upper cover plate, and the residual space inside is filled with quartz sand; and the free end of the magnetostrictive material is coated with a sound-absorbing material layer. The cooling deviceand method for the fin type industrial magnetostrictive type ultrasonic transducer disclosed by the invention avoids a leakage problem which possibly appears by adopting a cooling water or cooling liquid cooling way, reduces production and management cost, and ensures long-period stable work of the industrial ultrasonic transducer.

Description

technical field [0001] The invention relates to the technical field of ultrasonic transducers, in particular to a finned industrial magnetostrictive ultrasonic transducer cooling device and method. Background technique [0002] Magnetostrictive materials have high energy density and relatively good thermal conductivity. The power ultrasonic transducers made of them are very powerful and have been gradually used in the crude oil electric desalination industry. Since this kind of transducer is always working in a high-intensity and high-frequency magnetic field, various losses are very serious, and the heat generated is very large, and the magnetostrictive material is very sensitive to the external temperature. The stable work of the cycle is consistent with the output of the ultrasonic wave, which needs to be cooled. [0003] The prior art generally adopts cooling methods of air cooling or circulating water cooling. Among them, natural wind cooling or forced fan cooling can...
