| Abstract: | A large area soldering technology on connecting LD10 aluminum alloy saddle and 1Cr18Ni9Ti stainless steel tube has been researched to solve the hard bonding problem of evaporation. The effects of solder adding method and soldering temperature on the equity of soldering joints have been investigated. The microstructures of joint are analyzed. ANSYS software was used to simulate heat transfer performance of evaporator and analyze the effect of different degrees of soldering defects on heat transfer performance of evaporator. A complete set of the soldering production process of evaporation has been designed finally. |
