The Printed Circuit Heat Exchanger (PCHE) is a compact and high-performance heat exchanger. It is manufactured by chemically etching microchannels on a metal plate and connecting these channels through diffusion welding into a sturdy core structure. This heat exchanger is specifically designed for extreme working conditions, featuring excellent heat transfer efficiency, extremely high pressure resistance, and outstanding reliability. Moreover, it occupies significantly less space compared to traditional heat exchangers.
Due to its fully welded microchannel design, printed circuit heat exchanger has been widely used in applications involving high-pressure gases, high temperatures, corrosive media, low-temperature processes, and compact energy systems with high requirements. Its typical application fields include hydrogen energy, liquefied natural gas, oil and gas, supercritical carbon dioxide systems, chemical processing, and advanced power generation.
