Design, Fabrication, and Testing of Ceramic Plate‐Type Heat Exchangers with Integrated Flow Channel Design
Source abstract
Abstract
Novel plate‐type heat exchangers (HXs) with high‐power densities are proposed based on novel integrated flow channel designs. Net‐shape plates were achieved by the molding of powder mixtures to wood‐based composites (WBC's). HX stacks are built by plate‐to‐plate joining followed by pyrolysis and silicon melt infiltration. The C/SiSiC provided with PyC–SiC coating was gas‐tight to helium up to 5.5 MPa. Corrosion tests with coupons were performed using a ternary eutectic fluoride salt (FLiNaK) as the intermediate heat transfer fluid. While SiC is vulnerable to corrosion by the salt, the coating offers a high degree of protection to the ceramic substrate.
