Vacuum insulation of liquid nitrogen storage tanks
Liquid nitrogen storage tanks use vacuum insulation technology to effectively isolate heat transfer by creating a high vacuum layer between the inner and outer tanks.
Liquid nitrogen storage tanks use vacuum insulation technology to effectively isolate heat transfer by creating a high vacuum layer between the inner and outer tanks, thereby maintaining the extremely low temperature of liquid nitrogen. The inner tank usually uses low-temperature resistant stainless steel or aluminum alloy, while the insulation layer may include polyurethane foam, glass wool or high-performance insulation materials, and is equipped with a reflective coating to further reduce heat entry. The integrity of the vacuum layer must also be guaranteed in the design to maintain its insulation performance.
