Claims (1)

A tubular heat exchanger containing a transversely streamlined bundle of pipes, the surface of which is divided along the length into equal sections of constant diameter with parallel axes eccentrically offset relative to each other, forming, together with transitional necks - surface elements, cylindrical bends, and collectors with tube plates, characterized in that sections - the elbows of the outer tubular surface are made alternating and sequentially located along the flow of the coolant, in addition, with a corridor (linear) lump the axis of the same type (adjacent) end sections - the knees coincides with the vertices of the beam pipes at opposite horizontal bases of the breakdown parallelogram (as well as the lines connecting the centers of the axes) forming equal passage sections along the flow; with a checkerboard (triangular) layout, the axes of the same type of pipe end sections - the knees are located coinciding with the vertices of the triangle of the breakdown of the pipe boards, providing rational conditions for the flow around the pipe surface and the minimum allowable annular distances.
