Background
The existing vacuum tank for preserving biological samples is generally a tank body which is formed by welding stainless steel and has a plane bottom, and when preserving, operators put the biological samples into the vacuum tank, and then the vacuum tank is directly placed on the ground. The vacuum tank occupies a large area, the warehouse is not efficient to use, and the top of the vacuum tank is designed to be not sealed with a tank plug in order to prevent high pressure from forming inside. Irregular air leakage is thus easily generated. More importantly, because the liquid nitrogen is stored at the bottom of the heat preservation tank, an uncontrollable temperature difference from low temperature to room temperature is formed between the surface of the liquid nitrogen and the ventilation plug at the top of the liquid nitrogen, so that the biological preservation effect is affected.
In view of the above-mentioned drawbacks, the present inventors have actively studied and innovated to create a new structure of vacuum refrigerated cabinet, which has more industrial utility value.
