PURPOSE:To enhance the cooling capacity of a container main body, by providing a jacket chamber, which is provided around the container main body and has a heat exchanger provided therein, apart from a liquid sump part and connecting both of them by a pipe provided with the second heat exchanger. CONSTITUTION:A jacket chamber 4 is provided around a container main body 1 and a heat exchanger 6 is provided in said jacket chamber 4. A liquid sump part 12 equipped with an electromagnetic induction heater 13 and having a heating medium sealed therein under vacuum is provided apart from the jacket chamber and both of them are connected by connection pipes 17, 18 and the second heat exchanger 19 is provided to the connection pipe 17. The container main body 1 is heated at first by the heating medium 5' evaporated by the electromagnetic induction heater 13 and subsequently cooled by the condensed heating medium 5 condensed by the heat exchanger 6. Since temp. drops and the quantity of vapor is reduced when cooling is advanced by the liquid condensed by the heat exchanger 6, the condensed liquid due to the heat exchanger is supplied. |
