Abstract

The invention discloses Stirling cold insulation equipment. The equipment comprises a cold insulation container and a Stirling cryocooler, wherein a cold head of the Stirling cryocooler and the cold insulation container are arranged in a spaced mode; the cold insulation equipment further comprises a heat transfer component, and the heat transfer component comprises a first thermosiphon and a second thermosiphon; the first thermosiphon and the second thermosiphon are fixedly connected to the cold head and arranged on the periphery of the cold insulation container in a surrounding mode; and the first thermosiphon is arranged at a position higher than the second thermosiphon, and a refrigerating capacity Q1 of the first thermosiphon is smaller than a refrigerating capacity Q2 of the second thermosiphon to uniformly refrigerate an object placed in the cold insulation container. The Stirling cold insulation equipment can solve the problems that the cold insulation equipment is slow in cooling and uneven in temperature distribution in the vertical direction.

Description

technical field [0001] The invention relates to the technical field of Stirling refrigeration, in particular to a Stirling cold storage device. Background technique [0002] As a heat exchange device, the thermosiphon has the characteristics of high heat exchange efficiency, no moving parts, and no need for additional energy drive. By filling the pipe of the thermosiphon with refrigerant, the spontaneous flow and phase change of the refrigerant working medium The process achieves the purpose of efficient heat transfer. Thermosiphons are widely used in aerospace, solar heat collection, heat recovery, and cold chain transportation. [0003] Existing thermosiphon tubes are used as cold delivery methods for refrigerators, all of which are single-circuit refrigerant working fluids. This design can be understood in conjunction with the Stirling cold storage equipment disclosed in patent application CN202020220607.1. Under certain working conditions, the thermosiphon can only exc...
