Abstract

The invention discloses an ultra-low temperature refrigerator. The ultra-low temperature refrigerator comprises a refrigerator body, a refrigerator door, a sealing piece, an air inlet pipe, a hot airdevice and a refrigerating system, the refrigerator door is hinged to the refrigerator body, a mounting groove is formed in the side, close to the refrigerator body, of the refrigerator door, the sealing piece comprises a heat insulation air bag and a mounting part arranged on the heat insulation air bag, the mounting part is arranged in the mounting groove, the hot air device is arranged in the refrigerator door and communicates with the heat insulation air bag through the air inlet pipe, and the refrigerating system is arranged at one end of the refrigerator body. Hot air is guided into theheat insulation air bag, the sealing piece is softened through the hot air to deform and recover, and the refrigerator body and the refrigerator door are kept sealed to prevent cold leakage.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to an ultra-low temperature refrigerator. Background technique [0002] With the rapid development of the biological and medical industries, there is an increasing demand for ultra-low temperature refrigerators for long-term storage of biological and medical samples, reagents and other biological materials. Such ultra-low temperature refrigerators generally require storage temperatures below -70°C and a stable refrigeration system to achieve long-term reliable storage of biological materials. The door seal structure of ultra-low temperature refrigerators is similar to that of domestic refrigerators, and they are all sealed with sealing strips. However, the sealing strip will be deformed after being used for a certain period of time, and there is a large gap between the sealing strip and the refrigerator cabinet after the refrigerator door is closed, causing problems...
