Advantages of Etching in PCHE Plates Manufacturing
- Precision Microchannel Fabrication: Enables ultra-fine, complex flow paths (<0.5mm) for maximized heat transfer efficiency and uniform fluid distribution.
- Design Flexibility: Supports customizable channel geometries (zigzag, wavy) tailored to thermal/fluid dynamics requirements.
- Material Integrity Preservation: Stress-free etching avoids mechanical deformation, maintaining plate strength for high-pressure operations (up to 600 bar).
- Scalability & Consistency: Photochemical processes ensure repeatable, large-scale production of corrosion-resistant plates (e.g., stainless steel, alloys)
The production process of chemically etching PCHE Plates
1) Material selection (stainless steel/titanium);
2) Surface cleaning;
3) Photoresist coating and UV masking to define flow channel patterns;
4) Exposing and Developing;
5) Chemical etching to dissolve exposed areas;
6) Post-processing (resist removal, residue neutralization);
7) Quality inspection.
Precise control of etching parameters (time, temperature, concentration) ensures uniform channel geometry for optimized gas distribution, conductivity, and corrosion resistance while maintaining structural integrity. This method supports scalable, cost-efficient mass production.
