Printed Circuit Heat Exchanger
Product overview (purpose)
Printed Circuit Heat Exchanger (PCHE) is one of the Microchannel type of heat exchangers available as alternatives to shell and tube heat exchangers. Its name is derived from the procedure used to manufacture the flat metal plates that form the core of the heat exchanger which is done by chemical milling. These plates are then stacked and diffusion bonded, converting the plates into a solid metal block containing precisely engineered fluid flow passages.

Advantages
High heat transfer surface area per unit volume resulting in reduced weight, space, and supporting structure.
Can be used for temperature ranges of -200 to 900℃ and pressure ranges of 450bar.
Four to six times smaller than conventional designs such as shell-and-tube exchanger
Extremely high heat transfer coefficients are achievable with small-hydraulic diameter flow passages.
Can be used for gases, liquids, and two-phase flows.
Can be easily designed and manufactured for three stream Heat Exchanger.
