いる。Next, the operation of the conventional cryogenic liquid supply device shown in FIG. 5 will be described. First, the low temperature liquid 1 is supplied from the liquid pumping port 7 into the inner tank 3 and stored therein. The low temperature liquid storage container 2 has a sealed double tank structure in which a vacuum is provided between the inner tank 3 and the outer tank 4 and a super insulation 6 is arranged, and heat storage from the outside is prevented. The consumption accompanying evaporation of the low temperature liquid 1 present is reduced.

輸送用細管１０の出口の圧力とつりあってしまう。Here, the liquid transporting thin tube 10 from which moisture and air have been expelled by gas replacement is inserted from the liquid pumping port 9, and the tip of the liquid transporting thin tube 10 is immersed in the low temperature liquid 1. At this time, the temperature of the liquid-transporting thin tube 10 is much higher than that of the low-temperature liquid 1.
Is vaporized, and the pressure on the liquid surface of the low temperature liquid 1 temporarily rises. However, since the heat capacity of the tip of the liquid transport thin tube 10 is not so large, the pressure immediately balances with the pressure at the outlet of the liquid transport thin tube 10.

部に連続的に輸送供給される。Therefore, the gas release valve 13 is opened, gas is introduced into the inner tank 3 from the pressurizing gas cylinder 11 through the pipe 12, and the inner tank 3 is pressurized to a predetermined pressure. The pressure in the inner tank 3 can be monitored by the pressure gauge 16, and is controlled by opening and closing the gas release valve 13, the safety valve 14, and the safety source valve 15. Further, for example, when the pressure in the inner tank 3 rises abnormally due to bumping of the low temperature liquid 1 or the like, the emergency release valve 18 is opened to reduce the pressure in the inner tank 3. By making the pressure in the inner tank 3 higher than the pressure at the outlet of the liquid transport thin tube 10 in this manner, the low temperature liquid 1 is continuously transported and supplied to the outside through the liquid transport thin tube 10.

When the low temperature liquid 1 is to be supplied, the liquid transporting thin tube 10 is inserted from the liquid pumping port 9, the tip of the liquid transporting thin tube 10 is immersed in the low temperature liquid 1, and the supporting rod 20 is further added.

れる。Generally, when heat energy is applied to a liquid, the liquid is vaporized by radiant heat from a heating element. There are three types of heat transfer: radiation, conduction, and convection. Of these, radiant heat is represented by the following equation, and the contribution of transfer is much larger than the other two. Q = σA (T 4 −t 4 ) ε 1 ε 2 / (ε 1 + ε 2 −ε 1 ε 2 ), where Q is the energy carried and σ is the Stefan constant (5.7 × 10 −12 W · cm − 2). -K- 2 ), A is the area, T is the temperature on the high temperature side, t is the temperature on the low temperature side, and ε 1 and ε 2 are the emissivity on the high temperature side and the low temperature side, respectively, and usually take a value of 0.01 to 1. In particular, in a cryogenic liquid such as liquid helium, t is too small even if T is not so large.
It becomes a big energy. The latent heat of vaporization at the boiling point is 20.9 J / g for helium and 126.1 J / g for nitrogen. In addition, the amount of vaporized gas is 22.4 l of gas when helium vaporizes 4 g of liquid,
Nitrogen vaporizes 28 g of liquid to form 22.4 l of gas. Therefore, a large amount of gas can be obtained by vaporizing a liquid containing less helium.

On the other hand, in order to vaporize 28 g of nitrogen, energy of 3528 J is required, and if it is supplied in 5 minutes, it will be 12 J / sec, that is, 12 W.

しまうことがある。Here, if the amount of heat given to the low temperature liquid 1 is too large, the pressure in the low temperature liquid storage container 2 rises too much, excess gas is released from the safety valve 14, and conversely the amount of heat given is too small. It is difficult to vaporize the low temperature liquid 1, and it is necessary to control the amount of heat applied to the low temperature liquid 1. For example, when a metal heater such as a nichrome wire having a large heat capacity is immersed in the low temperature liquid 1, for example, liquid helium,
Bumping may occur, releasing more liquid helium than necessary.

に供給できる効果がある。According to the first embodiment, since the carbon sheet 21 is used as the low-temperature liquid vaporizing means, the heat capacity is smaller than that of the metal heater, the amount of heat given to the low-temperature liquid 1 can be easily controlled, and it can be continuously used. There is an effect that the low temperature liquid 1 can be stably supplied to the outside.

る。When the low-temperature liquid vaporization means is permanently attached to the low-temperature liquid storage container 2, heat cannot be prevented from entering from the fixed portion of the low-temperature liquid vaporization means, so that the low-temperature liquid 1 is not supplied. Due to this heat intrusion, the low temperature liquid 1 is constantly vaporized, the amount of the low temperature liquid 1 evaporated and consumed is large, and it is necessary to have a structure that further reduces heat intrusion. Is attached to the low-temperature liquid storage container 2 only when the low-temperature liquid 1 is supplied, the structure is simple, and the evaporation consumption of the low-temperature liquid 1 other than when the low-temperature liquid 1 is supplied can be reduced. This has the effect of facilitating maintenance such as failure of the seat 21.

Power is supplied to the ultrasonic vibrating body 25 from the lead wire 22 to vibrate the ultrasonic vibrating body 25. When vibration energy is applied to the low temperature liquid 1, fluctuation occurs at the interface with the ultrasonic vibrating body 25. In the low-temperature liquid 1 such as liquid helium or liquid nitrogen, vaporization occurs from the surface of the ultrasonic vibrating body 25 even with ultrasonic waves of relatively weak energy, the pressure in the inner tank 3 rises, and the liquid passes through the liquid transport thin tube 10.
