1. Air cooling: This is one of the most basic ways of heat dissipation. By forming free convection between the ultrasonic tool head and the environment, the generated heat is transferred to the air and taken away by the convection of the air. Although this method is low-cost, the heat dissipation effect may be relatively limited.

2. Liquid heat dissipation: Install heat sinks or tubes on the casing of the ultrasonic tool head, and then circulate the liquid (such as coolant) through the heat sinks/tubes to remove the heat from the probe. This cooling method has good heat dissipation effect, but the cost may be relatively high.

3. Metal shielding: Cover the outer shell of the ultrasonic tool head with a layer of metal film or metal mesh, which not only provides insulation but also helps with heat dissipation to a certain extent. However, please note that metal shielding may have a certain impact on signal detection and imaging/

4. Optimize working environment: Ensure that the ultrasonic tool head works in a well ventilated environment, avoiding placing it in a closed or high-temperature environment to reduce heat accumulation.

5. Adjusting working parameters: If the overheating of ultrasonic tools is caused by prolonged use or excessive power, the working parameters can be adjusted appropriately, such as reducing power or usage time, to reduce the generation of heat.

6. Adopting advanced heat dissipation technology: With the development of technology, some advanced heat dissipation technologies, such as water-cooled heat dissipation, are gradually being applied to ultrasonic equipment. This technology can more effectively lower the temperature of the equipment and maintain its stable operation.

7. Regular maintenance: Clean and maintain the ultrasonic tool head regularly to ensure that its surface is free of dust, dirt, or other obstacles, in order to maintain its good heat dissipation performance.

Please note that the above methods may need to be selected and implemented based on specific application scenarios and factors such as the model and specifications of the ultrasonic tool head. Before implementing any cooling measures, please carefully read and follow the relevant usage and maintenance instructions.
