みられた。DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the conventional example as described above, since the structure of the spiral heat exchange section 9 has two or more heat transfer plates spirally wound, the outer peripheral body is not a perfect circle. . In particular, even when the outermost peripheral edge that has been wound has a shape with a curved step due to the blockage of the flow path, or when mounting an outer peripheral cylinder of another component to obtain pressure resistance, this outer peripheral cylinder is not a perfect circle. Absent. Therefore, since the outer shape of the body 10 is different from that of the perfectly circular body 10 that is mounted above or below the heat exchanging portion 9 or both of them, it is not possible to directly join them. The flanges are welded together and bolted together. However, it is extremely difficult to weld along the inner diameter of the flange on the outer circumference of the heat exchange portion 9 having the stepped shape, and the flange shape becomes complicated.

Since the width of this flat ring includes the maximum diameter and the minimum diameter of the outer peripheral wall of the heat exchange portion, the entire circumference of the end edge surface of the heat exchange portion is in contact with the ring, and the welding work is performed. It is easy and the sealing effect is reliable. The body part attached above or below the heat exchange part, or both can form the edge part in a perfect circle shape, and it becomes easy to use a flat ring.
