Online Measurement of Full-Wave Diameter and Full-Wave Pitch of Corrugated Water-Cooled Plates

I. Project Background

In the fields of new energy vehicles and high-end equipment thermal management, corrugated water-cooled plates serve as core thermal management components, whose structural precision directly determines heat dissipation efficiency and assembly reliability. Traditional contact measurement suffers from low efficiency and easy damage to workpiece surfaces, while ordinary vision measurement is limited by resolution and light interference, making it difficult to meet micron-level accuracy requirements.

With high-precision detection, real-time data processing and automatic control capabilities, Shenshi Intelligent SG Series Laser Displacement Sensors stand out in the online measurement of full-wave diameter and full-wave pitch of corrugated water-cooled plates, becoming an important technical support for intelligent manufacturing quality control.

II. Inspection Requirements

• Measurement Items: Full-wave diameter and full-wave pitch of corrugated water-cooled plates

• Workpiece Dimensions: Approximately 2370×70×7 mm

• Accuracy Requirements: Full-wave diameter ±0.03 mm, full-wave pitch ±0.03 mm

• Speed Requirement: 160 mm/s

III. Case Sharing

Based on the laser triangulation measurement principle, the Shenshi Intelligent SG5050 Laser Displacement Sensor establishes a high-precision measurement system. It can acquire high-density data points with small spacing at a sampling frequency of up to 590 kHz and a repeatability accuracy of 0.025 μm.

In this way, the laser displacement sensor can completely and meticulously capture the details of the corrugated surface profile, providing a solid data foundation for the subsequent accurate calculation of the fitted circle diameter and center-to-center distance of the corrugated grooves, and realizing real-time and precise measurement of the surface profile of corrugated water-cooled plates.

Measurement Results: After 10 dynamic measurements, the repeatability of the fitted diameter of the water-cooled plate is 0.014 mm, and the full-wave pitch is 0.011 mm, meeting the measurement requirements of ±0.03 mm for full-wave diameter and ±0.03 mm for full-wave pitch.

Compared with other types of sensors, the Shenshi Intelligent SG Series Laser Displacement Sensors not only ensure high-precision measurement but also have outstanding speed advantages and environmental adaptability. Without contacting the workpiece surface, they avoid damage to the workpiece and effectively resist light interference, maintaining stable and reliable measurement performance in complex industrial environments, which highly matches the high-precision inspection requirements of corrugated water-cooled plates.
