Title:
OUTER LAYER CLADDING MATERIAL FOR HEAT EXCHANGER HAVING EXCEPTIONAL CORROSION RESISTANCE IN ROOT PORTION, AND HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2020/121978
Kind Code:
A1
Abstract:
This outer layer cladding material for a heat exchanger exhibits the potential difference relationship E3 < E1 < E2, where E1 is the potential of a core material, E3 is the potential of eutectic solder of a filet formed at a joining part of a material to be soldered and the outer layer cladding material of the heat exchanger, and E2 is the potential of the material to be soldered. In addition, the potential difference ΔEA between E3 and E2 is 105 mV or higher, and the potential difference ΔEB between E3 and E1 is 80 mV or higher.
