提出了一种基于新型集成流道设计的高功率密度板式换热器。通过将粉末混合物成型为木质复合材料（WBC）来实现网状板。HX堆是通过板对板连接，然后热解和硅熔体渗透建立的。具有PyC-SiC涂层的C/SiSiC对氦气的气密性高达5.5MPa。使用三元低共熔氟化物盐（FLiNaK）作为中间传热流体进行腐蚀测试。虽然SiC易受盐的腐蚀，但涂层为陶瓷基材提供了高度的保护。
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.
