A novel type of slotted fin was designed. The flow and heat transfer characteristics of the novel slotted fin were studied by experiment and numerical simulation. The influences of fin pitch and relative slotted height on the heat transfer and resistance characteristics of the novel slotted fin were analyzed. The relevant flow and heat transfer correlation was obtained by power function multivariate nonlinear fitting. Research showed that the shell side comprehensive heat transfer performance of the novel finned tube was 1.46—1.64 times higher than that of the plain finned tube. When Reynolds number
