Problems solved by technology

[0003] Liquid nitrogen biological container is a device that uses ultra-low temperature to preserve biological samples. In existing liquid nitrogen biological containers, the part with liquid nitrogen at the bottom has a lower temperature, while the part at the top that is far away from liquid nitrogen increases with the storage time. The greater the temperature difference between it and the bottom, resulting in defects in preserved biological samples and a waste of resources

Abstract

The invention relates to a liquid nitrogen biological container capable of reducing temperature difference in a cylinder. The container comprises an outer cylinder body (1), an inner cylinder body (2) and heat transfer elements, the inner cylinder body (2) is arranged in the outer cylinder body (1), liquid nitrogen is arranged in the inner cylinder body (2), the multiple heat transfer elements are uniformly arranged on the inner wall of the inner cylinder body (2), the top ends of the heat transfer elements reach the lower side of the top of the inner cylinder body (2), the bottom ends of the heat transfer elements are immersed in the liquid nitrogen; the heat transfer elements are capillary tubes (4) or heat tubes. The multiple capillary tubes or heat tubes are uniformly distributed on the inner wall of the cylinder body, the bottoms can be immersed in the liquid nitrogen, and the liquid nitrogen rises along the capillary tubes or the heat tubes under the capillary action of the capillary tubes or the heat tubes, so that the temperature of the upper part of the cylinder body is reduced, the liquid nitrogen evaporates at the top and then falls into the liquid nitrogen at the bottom, a circulating temperature control system is formed by rising and evaporation falling of the liquid nitrogen, and the upper-lower temperature difference in the cylinder body is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of biological sample storage, in particular to a liquid nitrogen biological container that reduces the temperature difference in a cylinder. Background technique [0002] Long-term storage of biological samples usually uses as low a temperature as possible to reduce the biochemical reactions of biological samples, so as to improve the stability of various components in biological samples. The traditional cryogenic storage of biological samples is mainly realized by compressor refrigeration storage and liquid nitrogen storage. [0003] Liquid nitrogen biological container is a device that uses ultra-low temperature to preserve biological samples. In existing liquid nitrogen biological containers, the part with liquid nitrogen at the bottom has a lower temperature, while the part at the top that is far away from liquid nitrogen increases with the storage time. The larger the temperature difference between it ...
