The aluminum alloy liquid nitrogen container is mainly composed of an outer shell, an inner liner, a neck tube, a multilayer insulator and a bucket. The container shell and inner liner are made of aluminum alloy, which has the characteristics of light weight, high strength at low temperature, and corrosion resistance. The neck tube is made of glass fiber reinforced plastic, which is of high mechanical strength and low thermal conductivity.
Features
The multi-layer insulator uses aluminum foil as the reflective screen, which is with excellent reflective performance. And it uses the material with low thermal conductivity and low outgassing rate as thermal insulation materials to reduce heat radiation. The interlayer between the container shell and the inner liner is in high vacuum state which can prevent thermal convection of the gas. And the adsorbent with a large adsorption capacity at low temperature is used to ensure long-term stable and reliable performance of the container and long product life.
