[0005] The heat dissipation structure of the transmitting transducer includes: an active heat dissipation structure and a passive heat dissipation structure; among them, the active heat dissipation structure adopts a water cooling method, and by adding a circulating water cooling structure inside the transducer, the heat of the transmitting transducer is passed through heat exchange. Afterwards, it is taken away as soon as possible, and its heat dissipation ability is strong, and it can be used for a long time. However, the active heat dissipation structure is a circulation heat dissipation structure, and its structure is relatively complicated. In order to meet the requirements of circulation and corrosion resistance, various auxiliary equipment must be added , not suitable for large depth and convenient operation

Description
technical field [0001] The invention belongs to the technical field of acoustic sensors, and in particular relates to a multi-channel heat dissipation structure for flextensional transducers. Background technique [0002] The development of submarine noise reduction and stealth technology has brought great challenges to submarine target detection. Therefore, active detection will be the only effective technical means for long-distance detection of submarines. High-power underwater acoustic emission transducer is an important part of active detection sonar, and its main performance indicators directly determine the technical level of sonar. [0003] With the continuous development of modern transmitting transducer technology, the input electric power of a single high-power underwater acoustic transmitting transducer can reach nearly 100 kilowatts. Therefore, more than 40% of the input electric power is consumed in various forms of useless energy, most of which are dissipated...
