The Design of the Miniature Thermo Tank for a Cell Culture System in a Biocabin

Introduces a miniature mesothermal thermo tank which is designed for a cell culture system in a biocabin carried by a recoverable satellite, the using temperature of the thermo tank ranges from -20℃ to 80℃, the exterior size of the box is 40 cm, 40cm, 40cm, the temperature fluctuation in the box is controlled under 37 ±0.5℃. To obtain an efficiently constant temperature in a small space, adopts an portable and small semiconductor refrigeration system which is easy to control. Furthermore, makes an experimental investigation on the semiconductor refrigeration to analyze the parameters that affect the performance, which provides basal gist for the research of the system.
