The spiral-casing tubular heat exchanger for fluid partition wall heat transferring heat exchanger consists of central pipe, spiral plate, and outer cylinder to constitute one axial spiral passage, and the tube array is arranged concentrically via the passage axially. The present invention features that the centrifugal force the spiral flow channel produces disturbs the inner layer and interface of the laminar flow and the elliptical streamline the tube array section forms inhibits the fluid from drag force and tail flow effect and these increases the heat transferring coefficient and reduces flow resistance. |
