CFD analysis andheat transfer characteristics of printed circuit heat exchanger

Journal of Thermal Engineering, 2022
This paper aims to investigate the cubical fins and the thermal-hydraulic characteristics in a Printed Circuit Heat Exchanger (PCHE). The working fluid is considered a supercritical LNG. The outcomes show that the thermal-hydraulic performance is enhanced using the cubical fins comparing it to the straight channel. The maximum and minimum difference of

Experimental and numerical study of a printed circuit heat exchanger [PDF]

Annals of Nuclear Energy, 2016
Abstract Printed circuit heat exchangers (PCHEs) are promising to be employed in very-high-temperature gas-cooled reactors (VHTRs) due to their high robustness for high-temperature, high-pressure applications and high compactness. PCHEs typically serve as intermediate heat exchangers (IHXs) that isolate the secondary loop from the reactor’s primary ...

Numerical Analysis on Longitudinal Heat Conduction in Printed Circuit Heat Exchanger

Korean Journal of Air-Conditioning and Refrigeration Engineering, 2014
Abstract Longitudinal heat conduction is known to be an important factor in the design of a printed circuit heat exchanger(PCHE) for cryogenic applications. Parasitic heat conduction through the heat exchanger frame needs to be considered because it isknown to decrease the effectiveness of the heat exchanger.
