Background
In the existing spiral plate type heat exchanger without a semi-cylindrical structure (as shown in fig. 3), an inlet and outlet structure of the excircle of a spiral body is mostly a tangential necking structure. The manufacturing method of the tangential necking structure is to make the tangential necking from the extended part of the spiral plate by lofting according to the size of the connected square and round connecting pipe. The square head end of the square and round connecting pipe is welded with the tangential necking. The technical limitations of such a structure are: 1. the tangential necking is a flat plate structure, and has poor bearing force, easy deformation and low bearing capacity. So that the design pressure and the spiral diameter of the spiral plate heat exchanger without the semicylinder are limited. 2. Because the tangential necking and the square and round connecting pipe are assembled in a butt joint mode and an angle joint mode, and the thickness of the plate is thinner, the assembling size of the tangential necking and the square and round connecting pipe is not easy to guarantee, assembling gaps are not uniform, and the assembling quality of the tangential necking and the square and round connecting pipe is unstable. The unstable assembly quality makes the welding quality between the tangential necking and the square and round connecting pipe difficult to guarantee, and the welding seam has poor forming appearance. 3. The orientation of the pipe orifice is limited, and the orientation of the inlet and outlet pipe orifices can only be tangential because the direction of the tangential necking is always tangential along the spiral body.
