극저온 열교환기의 축방향 열전달 억제

Abstract

The purpose of this research is to develop the high effectiveness heat exchanger for LNG liquefaction plant. A newly developed type micro-channel PCHE which has a low axial heat conduction design has been developed using chemical etching and diffusion bonding techniques. The experiment with helium gas experimental apparatus has been conducted. Experimental results indicate that reducing axial conduction area and increasing axial conduction length increased the effectiveness of PCHE.
