PURPOSE:To improve the passing performance (head loss) of pumping water and make dusts or the like flow through the inside of the group of cooling pipes smoothly by a method wherein the group of the cooling pipes are arranged on a concentric circle under keeping a proper distance between the inner peripheral wall of a main body while the diameter of the concentric circle is designed so as to be larger than the diameter of the connecting port of a connecting part. CONSTITUTION:An arbitrary number of the straight cooling pipes 11 are arranged axially on the concentric circle 12 having the diameter of phid' under keeping proper distance (1) between the inner peripheral wall of the cylindrical main body 10 while both ends of each cooling pipes 11 are attached to annular tube plates 13a, 13b attached to both sides of the main body 10 on the concentrical circle 12. The cooling water flows into an inflow tank 15a through a suction pipe 16 and, subsequently, flows out to an outflow tank 15b through each cooling pipes 11. In this case, the cooling water is cooled by the pumping water of pump, which flows through the outsides of the cooling pipes 11. |
