| Abstract: | Based on theoretic analysis and process tests,the selective plating process of a heat exchanger made of different materials with large performance difference is investigated.The coating quality on different profiles and materials of the heat exchanger assembly is guaranteed by partial sheltering,etching solution selection and pre-plating process.The function requirements of solderability and high temperature oxidation resistance on each local coating of heat exchanger are satisfied.Therefore,the subsequent brazing and hot firing were successfully achieved.The plating process mentioned above has been applied to several heat exchangers with complex structure. |
