<P>PROBLEM TO BE SOLVED: To reduce the total flow rate of cooling water flowing in a branch pipe, and realize miniaturization and simplification of the constitution. <P>SOLUTION: A plurality of branch pipes 11-1 to 11-4 which are connected to an arbitrary position of the cooling pipes and branched off and in which cooling water flows are connected to a flow-path selection device 10 and either one of the connected plural branch pipes 11-1 to 11-4 is selected with the flow-path selection device 10, and the selected branch pipe is communicated with a low-pressure position of which the pressure is lower than that at the position of the cooling pipe connected to the selected branch pipe, and the cooling water which flows via the selected pipe is made to flow into the low-pressure position. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
