The heat exchanger pipe contains the body (2) and the partition (1) dividing it inside into two separate ducts for the flow of the agent. The partition (1) is spiral in shape and preferably is made of a rectangular metal strip curled around its vertical axis of symmetry and connected tight to the pipe body (2) along its whole length. The partition (1) may be of equal length as the pipe body (2) or shorter, where the ratio between the length of lay (2) of the curl of the partition (1) and the inner diameter (d) of the pipe body (2) is no less than ½, preferably ½. Preferably, the pipe is made of stainless steel. |
