As we all know, the temperature of liquid nitrogen is -196°C, what is the temperature of the liquid nitrogen tank?
To be precise, since the liquid nitrogen tank is made of aviation aluminum or stainless steel, it has a high-vacuum interlayer, and the interlayer is added with adsorption insulation material, which is super heat-insulating. Therefore, the liquid nitrogen tank is a low-temperature container used to hold liquid nitrogen. The temperature is normal temperature, 0 or above 0°C, not -196°C.
It is precisely because of these materials that the liquid nitrogen tank has the characteristics of high strength, corrosion resistance, high temperature resistance, and excellent heat preservation performance. It is used to hold liquid nitrogen at a temperature of -196°C without pressure. After nitrogen is injected into the liquid nitrogen tank, the temperature of the material inside the tank decreases with the increase of liquid nitrogen, and gradually synchronizes with the temperature of liquid nitrogen, that is, the temperature of the liquid nitrogen tank that everyone thinks is -196°C. Correspondingly, the temperature of the tank will also rise after the amount of liquid nitrogen is reduced.
In fact, if you want to check the temperature of the liquid nitrogen tank in real time, there is another way. Use the liquid nitrogen monitor to fix the temperature probe at a certain position of the liquid nitrogen tank, connect it to the cloud monitoring platform, and you can check the temperature of the liquid nitrogen tank at any time. temperature. Of course, the premise of this situation is that there is liquid nitrogen in the liquid nitrogen tank.
To sum up, it can be concluded that the temperature of the liquid nitrogen tank is not -196°C, but at room temperature, at 0 or above 0°C, now you know it.
Note: Because the temperature at the mouth of the tank is also very low, we must remember to wear gloves when storing and withdrawing frozen semen, so as to avoid frostbite and unnecessary losses.
