Title:
ULTRALOW-TEMPERATURE STORAGE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/022496
Kind Code:
A1
Abstract:
An ultralow-temperature storage system, comprising a refrigeration main machine (100) and a low-temperature storage tank (1). The low-temperature storage tank (1) comprises an inner shell (1-1), an outer shell (1-2), and a heat exchange pipeline (1-3) arranged in the inner shell (1-1) and used for allowing a secondary refrigerant to flow in the heat exchange pipeline; the refrigeration main machine (100) comprises a first pump (2), a second pump (3), a low-temperature refrigerator, a storage tank (9), and a heat insulation device (10); the second pump (3) and the low-temperature refrigerator are arranged in the heat insulation device (10); the first pump (2) and the storage tank (9) are arranged on a first pipeline (2-1); the second pump (3) is arranged on a second pipeline (2-2); the first pipeline (2-1) and the second pipeline (2-2) are connected in parallel; the storage tank (9) is used for storing a gas-phase secondary refrigerant in the first pipeline (2-1); the first pump (2) and the second pump (3) provide power for flowing of the secondary refrigerant in a secondary refrigerant circulation loop; and a cold disc of the low-temperature refrigerator is used for refrigerating the secondary refrigerant passing through the cold disc. The present invention can enable the low-temperature storage tank (1) to keep low temperature for a long time, such that the problems that the storage time of a low-temperature medium in the low-temperature storage tank (1) is short and the stored low-temperature medium is prone to volatilization are solved.
