Uniform Temperature Field Advantage: Ultrasonic Volumetric Heating and Thermocouple Multi-point Calibration for Precision Cleaning
Precision industrial cleaning processes such as electronic parts, optical components and aerospace accessories have extremely strict requirements on liquid temperature uniformity. Local temperature difference will lead to inconsistent cleaning strength, residual dirt in low-temperature areas and over-corrosion of workpieces in high-temperature areas, resulting in batch defective products. Traditional resistive heating cannot eliminate regional temperature gradient, while ultrasonic heating plates realize full-basin uniform volumetric heating, and matched thermocouple multi-point calibration ensures consistent temperature of all cleaning areas.
Resistive heating relies on surface heat source conduction, forming obvious temperature gradient from heating surface to liquid remote area. Even with long-term heat preservation, the temperature difference of different areas of the liquid basin still exceeds 1.5℃, which cannot meet the precision cleaning standard requiring temperature difference less than 0.5℃. Ultrasonic volumetric heating realizes synchronous heat generation in the whole liquid, with no heat source concentration and conduction attenuation process, and the overall temperature uniformity is greatly improved.
Multi-point thermocouple synchronous monitoring and calibration further eliminate tiny temperature differences in complex tank structures. For cleaning tanks with irregular structures and internal partitions, multi-point sensing layout captures temperature data of different regions, and the system dynamically adjusts vibration power to realize full-basin temperature balance. According to cleaning test data, this matching mode improves workpiece cleaning qualification rate by more than 6% compared with traditional heating systems.
