The liquid nitrogen tank only has a good vacuum to ensure the heat preservation effect of the container is good. What is the bad vacuum of the liquid nitrogen tank?
A: The liquid nitrogen tank is made of an aluminum plate. There is a liner inside the liquid nitrogen tank, which is the source of the vacuum of the tank. It needs to be wrapped in the inner tank. One more lap or one less circle will affect its insulation effect.
Someone here said that giving it a few layers will not increase its vacuum?
Tianchi liquid nitrogen tank technology: If you pack a few layers, it will not increase the insulation effect, but will not pump out the vacuum.
It is mentioned above that the degree of vacuum of the liquid nitrogen tank is directly related to the inner tank.
