Abstract (en)
[origin: WO2020023169A1] High heat flux furnace cooler comprise CuNi pipe coils cast inside pours of high purity (99%-Wt) copper. The depth of front copper cover over the pipe coils in the hot face to manufacture into the casting is derived from a projection of thermal and stress conditions existing at the cooler's end-of-campaign-life. CFD and/or FEA analyses and modeling is used for a trial-and-error zeroing in of the optimum geometries to employ in the original casting of CuNi pipe coils in high purity copper casting. Individual pipe coil positions to cast inside a copper casting mold are secured with devices that will not melt, cause thermal shear stresses, or be the source of contaminations or copper defects. Pipe bonding to the casting results because the differential coefficient of expansions of the pipes' and the casting's copper alloys involved do not exceed the yield strength of the casting copper during operational thermal cycling.
