に高くつき、窒素ガスの浪費が問題となつた。 In the temperature raising equipment shown in Fig. 1, the state of the nitrogen gas passing through the blower 4 at the start of operation is -196°C and the pressure is atmospheric pressure, and at the end of operation the temperature is 100°C.
The pressure is about 5Kg/cm 2 G. There are no standard blowers that meet these specifications, and the blowers have special specifications, making them very expensive equipment. Also, the second
In the illustrated method, nitrogen gas, which is a heating medium, is thrown away without being recycled, resulting in very high operating costs and waste of nitrogen gas.

するものである。 An object of the present invention is to solve the above problems. That is, the purpose of the present invention is to reduce operating costs in the above-mentioned temperature raising equipment by not using a specially designed blower and by recycling a portion of the nitrogen gas.
However, in the present invention, in order to raise the temperature of a heat absorption plate that has been cooled to an extremely low temperature (for example, -196°C), heated nitrogen gas is used as a heating medium, and this is blown into the piping system of the heat absorption plate, and the nitrogen gas on the outlet side is heated. A portion of the nitrogen gas is recycled using an ejector, making effective use of nitrogen gas.
以下、本発明の一実施例を第３図によつて説明

ならない。 An embodiment of the present invention will be described below with reference to FIG. In such equipment, liquefied nitrogen is supplied as a refrigerant to the heat absorption plate 2, and the heat absorption plate 2 is cooled to the liquefied nitrogen temperature. During this time, a vacuum is maintained within the equipment 1, and, for example, a predetermined test is performed. After completing the series of tests and before returning the interior to atmospheric pressure, the temperature of the heat absorbing plate 2 should be brought to room temperature or higher to prevent water droplets and dirt from adhering to the cooled surface of the heat absorbing plate 2. Must be.

浄を保つことができる。 For this reason, the liquid nitrogen inside the heat absorption plate 2 is extracted,
Next, heated nitrogen gas is blown into the heat absorption plate 2 piping system via the heater 3. The nitrogen gas passes through the heat absorption plate 2, performs heat exchange, and is discharged from the outlet through the nitrogen gas discharge valve 7.
It is then discharged. At this time, a part of the nitrogen gas is introduced into the nitrogen gas supply line by an ejector 8 operated by the nitrogen gas supplied through the nitrogen gas supply source valve 5, and is again supplied to the heat absorption plate 2 via the heater 3. be done. In this way, the heat absorbing plate 2 whose temperature has been raised to above room temperature can remain clean when the vacuum is broken.

定であることから操作も容易となる。 Since the present invention is as described above, there is no need to use a specially designed blower, and by using a general ejector, a part of the nitrogen gas is circulated and used, so the consumption of nitrogen gas is reduced. The amount can also be reduced. Furthermore, compared to the case of using a blower, the method of operation is easier because the pressure remains constant as the temperature changes.
