The utility model discloses a spiral winding tube type double-tube-plate heat exchanger which comprises a pair of outer tube plates arranged oppositely. A pair of inner tube plates is arranged between the two outer tube plates, a tubular casing is fixedly arranged between the two inner tube plates, a core tube is arranged in the tubular casing, a winding tube beam is arranged between the core tube and the tubular casing, two ends of the winding tube beam penetrate the inner tube plate and the outer tube plate to be fixedly connected, tube pass length is extended by means of the winding tube beam, shell pass inner fluid state is changed, fluid has a strong turbulence effect, and heat exchanging efficiency is improved. By means of spiral winding tube beam design, pipe vibration and the stress caused by thermal expansion and cold contraction can be effectively removed, the heat exchanger is protected, and the service life of the heat exchanger is prolonged. By means of a double-tube-plate structure, a material leaking detecting area can be formed, cross contamination of a pipe pass material and a shell pass medium is prevented, and material safety is guaranteed.
