Document Type and Number:
WIPO Patent Application WO/2019/218997
Kind Code:
A1
Abstract:
A method and device for filling a dry dewar tank. A low-temperature liquid is filled into a dry dewar tank that is provided with a porous adsorbent material capable of adsorbing the low-temperature liquid, and a vacuum state is reached inside of the dry dewar tank by means of vacuuming. The present method and device greatly increase the adsorption of a low-temperature liquid by a porous adsorbent material, may achieve rapid and efficient filling, obtain a high-quality cold source, and improve the effective cold preservation duration of the dry dewar tank.
