Description

Background
The magnetostrictive material has high energy density and relatively good thermal conductivity, and the power ultrasonic transducer manufactured by the magnetostrictive material has high power and is gradually applied to the crude oil electric desalting industry. Since such transducers always work in a high-intensity high-frequency magnetic field, various losses are severe, the heat caused by the transducers is very large, and magnetostrictive materials are sensitive to external temperature, so that the transducers need to be cooled in order to achieve the consistency of long-period stable work and ultrasonic output of the ultrasonic transducers.
The prior art generally adopts an air cooling or circulating water cooling mode. Wherein the natural wind cooling or the forced fan cooling can not meet the long-period production requirement of larger power; the circulating water cooling not only wastes water resources, but also has complex process flow and great difficulty in production management. For example, patent US 9142751B2 discloses a cooling device for a piezoelectric ceramic transducer, which adopts a double-layer jacket structure, the inner layer is filled with solid insulating heat-conducting glue, and the outer layer is cooled by cooling water circulating flow; the cooling mode of the circulating cooling water not only wastes water resources and consumes power, but also requires complex circulating water pipelines for a plurality of groups of ultrasonic transducers, the process flow is complex, the production management difficulty is high, and the cooling effect and the working state of the transducers can be influenced by scaling blockage, corrosion leakage and congealing of the cooling water.
Patents CN201920820262.0 and CN201910475380.7 disclose a method of not adopting circulating water cooling after improvement, which is realized by adopting a method of filling cooling liquid into a cavity, thereby saving water resource and power consumption, and avoiding the cooling effect and working state of the transducer from being affected by scaling, blocking, corrosion leakage and congealing of cooling water. However, this method has the following drawbacks: the cooling liquid is water, ethanol, propanol, glycol, glycerol and other cooling agents, the acoustic impedance of the cooling liquid is small, and part of sound energy is consumed in the cooling liquid in a heating mode; the cooling liquid cavity is easy to cause cooling liquid leakage along with the rise of the temperature, whether the cooling liquid leaks or not needs to be checked regularly, and the workload of production operators is increased; once leakage of the cooling liquid is found, the cooling liquid is required to be filled in a shutdown maintenance mode, and the long-period stable work of the industrial ultrasonic transducer is influenced.
The existing cooling mode of the ultrasonic transducer limits the industrial application and development of the ultrasonic transducer to a certain extent.
