Printed Circuit Heat Exchanger PCHE Plates Precision Chemical Etching
Product Overview
Xinhaisen manufactures precision chemical etched PCHE plates with high dimensional accuracy, burr-free edges and excellent consistency. Our photochemical machining process creates complex microchannel patterns that are difficult or impossible to achieve using conventional machining methods.
PCHE (Printed Circuit Heat Exchanger) etched plates are precision microchannel metal components produced by photochemical etching technology. They are used for compact heat transfer systems requiring high efficiency and high pressure resistance.
Key Features
Ultra-compact structure (up to 80% smaller than traditional heat exchangers)
High thermal efficiency microchannel design
Excellent pressure resistance
High precision photochemical etching process
Suitable for high-pressure hydrogen systems

Engineering Partnership: We work closely with clients to customize the PCHE design for their specific thermal, mechanical, and material challenges
Frequently Asked Questions
Q1: What is the advantage of using etched plates over machined plates for PCHE?
A: Etching produces burr-free, stress-free, and uniformly smooth channels without heat-affected zones. It also allows for much finer channel geometries (as small as 0.03mm) than traditional machining, and design changes are quick and inexpensive since no hard tooling is required.
Q2: What materials can you etch for PCHE plates?
A: We can etch stainless steel (SUS304, SUS316, SUS316L), titanium (Gr1, Gr2), Inconel, Hastelloy, copper, brass, and many other alloys commonly used in high-performance heat exchangers.
Q3: What is the minimum channel width you can achieve?
A: We can achieve channel widths as small as 0.03mm and ridge (wall) widths down to 0.015mm, depending on material thickness.
Q4: What is your typical lead time for PCHE prototype plates?
A: Prototype samples typically take 3-7 working days after design approval. Mass production lead times are 7-15 working days, with expedited options available for urgent orders.
Q5: Are your etched plates ready for diffusion bonding?
A: Yes. Because etching produces clean, burr-free, oxide-minimized surfaces, our plates are ideal for direct diffusion bonding or welding without additional surface preparation.
