Abstract

PURPOSE:To cool the whole inner tank to a uniform temperature by fitting fins for heat-exchanging with the evaporated low-temperature gas on the inner-wall surface of the inner tank. CONSTITUTION:A container of a low-temperature liquid 1 such as liquid helium, liquid nitrogen is constituted with an inner tank 2, a heat insulating layer 3, and an outer tank 4, and fins 6 made of a material having good conductivity such as Cu, Al in a shape capable of having a large surface area such as sheet foil, mesh are fitted to the inner-wall surface of the inner tank 2 by welding, soldering, etc. The evaporated low-temperature gas efficiently cools the whole inner tank 2 via the heat exchanging fins 6, and the evaporation speed from the container is suppressed. In addition, the heat infiltrating through a neck section 5 is absorbed by the evaporated gas, and the whole inner tank 2 is cooled to a uniform temperature. In case of a liquid helium container with a superconducting coil inserted in it, heat radiation from the upper section of the inner tank is small, thereby the container can be operated even if a magnet is almost wholly located in the gas.

Since heat enters the inner tank 2 due to radiation, the low temperature liquid 1
The evaporation rate is high, creating a temperature distribution in the inner tank, resulting in a high temperature.

Its feature is that fins are attached to the inner wall of the inner tank to exchange heat with the evaporated low-temperature gas.

That is, since the sensible heat of the evaporated gas is effectively used for cooling the inner tank, the rate of evaporation from the low temperature liquid container is suppressed. In addition, the heat entering from the neck is absorbed by evaporative gas or heat exchange, so the entire inner tank is cooled to a uniform temperature.
