Description
Technical Field
[0001] The utility model relates to the technical field of liquid nitrogen cooling equipment, in particular to a liquid nitrogen cooling and efficient cooling equipment. Background Art
[0002] Liquid nitrogen refers to the liquid obtained by inert, colorless, odorless, non-corrosive, and non-flammable nitrogen gas under extremely low temperature. Liquid nitrogen is an inert, colorless, odorless, low-viscosity, non-corrosive, non-flammable, transparent liquid at extremely low temperature. When it vaporizes, it absorbs a large amount of heat and causes frostbite. Nitrogen makes up most of the atmosphere (78.03% by volume and 75.5% by weight). At normal pressure, the boiling point of nitrogen is -196.56℃, and 1 cubic meter of liquid nitrogen can expand to 696 cubic meters of pure gaseous nitrogen (21℃). If pressurized, liquid nitrogen can be obtained at a higher temperature, but the current liquid nitrogen cooling and cooling equipment needs to stop the equipment when taking materials, resulting in low work efficiency. For this reason, we propose a liquid nitrogen cooling and efficient cooling equipment. Utility Model Content
