PURPOSE:To improve cooling efficiency, and to save liquefied gas by installing a control valve at the connecting point of a circulating circuit and the cooling water circuit of an article itself, in case of executing a test by connecting a cooling part and an article by the circulating circuit. CONSTITUTION:A cooling part 1 and a cooled body installing part 3 are connected by ducts 5, 16 provided with a circulating pump 2. An engine 7 provided with a radiator 6 is provided with pipes 14, 15, the radiator 6, and a circuit of a cooling water circulating through pipes 12, 13, and changeover valves 17, 18 are provided on connecting points of the pipes 5, 12 and 13, and the pipes 14, 15 and 16. In case of cooling, the engine 7 is stopped, and thereafter, only the engine 7 is cooled by operating the valves 17, 18 and connected the pipes 5, 16 to the pipes 13, 14 and the engine 7, and thereafter, the cooling water is supplied to the radiator 6 side by switching the valves 17, 18 to the side of the pipes 12, 15. After the cooling, the test is executed by detaching the pipes 5, 16 and starting the engine 7. |
