To ensure the quality of the experimental sample, it needs to be stored in a specific low temperature environment, and the requirements of temperature control precision and temperature uniformity are very high.
The ground low-temperature refrigerator adopts a mature cascade compression refrigeration technology, and the temperature uniformity index is easy to realize by directly cooling the refrigerator body through an evaporator coil or adopting an air cooling mode. Because the compressor can not adapt to the space microgravity environment, the Stirling refrigerator, the semiconductor refrigerator and the like are commonly used as cold sources on the orbit, the corresponding cold head part has smaller size which is generally not more than 100mm multiplied by 100mm and can only be locally contacted with the device.
Meanwhile, in a rail microgravity environment, natural convection cannot be realized for air in the device, the fan generally tolerates low temperature of not less than-40 ℃, the difficulty of dewing and icing prevention of the fan is high at low temperature, and the fan cannot be installed when the temperature level of the device is lower. Therefore, the temperature uniformity index of the space memory device is difficult to realize.
A space flight low temperature refrigerator (CN 201711287001.9) that china and technology university Liu Ji brought forward in Shanghai sets up special heat conduction system in the incasement, adopts structural slab such as backplate and baffle, and the requirement of box temperature homogeneity is realized to measures such as a plurality of heat pipes and graphite membrane combine together. The scheme has complex composition and high resistance to mechanical design difficulty, and simultaneously reduces the utilization efficiency of the storage space.
The zhuang he et al published in the low temperature engineering (5 th 2017) in the paper of-80 ℃ Stirling low temperature refrigerator development, two copper heat dissipation plates are adopted to enlarge the cold transmission area, and red copper fin plates are adopted to enhance natural convection heat transfer, but the box body still has larger temperature difference, and the weight cost is large, thus being not beneficial to space application.
The ground refrigerator generally adopts polyurethane foaming to insulate heat between the inner container and the outer shell, the mechanical property of the foam is poor, the ground refrigerator is generally only suitable for the mechanical environment under ground transportation load, the vibration acceleration in each direction can reach more than 10g when a rocket is launched, the impact can reach hundreds of g, the conventional heat insulation and structural design can not adapt, special vibration isolation consideration needs to be carried out, and design constraints and resource requirements are high.
The MELFI-80 ℃ low-temperature storage device of the international space station adopts an inverted Brayton refrigerator to manufacture an ultra-long cold finger (about 600 mm) to go deep into a storage area so as to solve the problem of temperature uniformity of the storage area, and adopts a stainless steel Dewar to realize heat insulation of the storage area. The system is complex and the weight cost is large.
