A bending traverse baffle heat exchanger includes a cylindrical housing, a left pipe plate, a right pipe plate, a pipe bundle supported by the helical traverse baffles, a fluid inlet connecting pipe, a fluid outlet connecting pipe, the pipe bundle of the heat exchange pipes and the pipe plates, which are characterized in that the left and right pipe plates are concentrically disposed and welded on two ends of the cylindrical housing; the pipe bundle of the heat exchange pipes penetrates into the pipe plates and is in expanding joint or welding with the pipe plates; the pipe bundle is supported by the helical traverse baffles; the projection of each traverse baffle occupies a part of the inner section circle of the cylindrical housing, which is vertical to the axis; two to five traverse baffles form a pitch; the projection of two to five traverse baffles, vertical to the axis of the cylindrical housing is the inner section circle of the cylindrical housing; and each traverse baffle is constituted by an elliptical curved edge and two straight edges, wherein one straight edge is added with a leakage-preventing bevel which is formed by bending.
