    • PURPOSE: A spiral heat transfer tube is provided to efficiently cope with the underwater pressure wave can be generated by the underwater explosion without using a vertical tube type heat delivery tube of a condenser used in a power plant. CONSTITUTION: A spiral heat exchange tube(3) has the both ends to be welded by a seawater separating plate(2). The seawater used for cooling water is flowed into a cooling water inlet(7) via a pipe(5) for the inflow of cooling water and then into the spiral heat exchange tube welded on the seawater separating plate. The seawater heated while condensing the vapors by flowing in the spiral heat exchange tube is discharged to a cooling water outlet(8) via the outlet of the spiral heat exchange tube and finally out of a condenser via a tube(6) for cooling water discharge. The heat transfer area per each tube is increased by multiple times compared to a vertical tube or a U-type tube so that the numbers of the heat exchange tubes can be reduced.
