“…The helium gas distribution and the heat capacity of the regenerator were affected by the positions and quantity of the rectification meshes. Two additional rectification meshes packed close to the hot end of the regenerator were optimal for improving the performance of the refrigerator [15]. The effects of the regenerator packing method on the cooling performance were tested.…”

With the wide application of high performance cryo-pumps, high and low temperature superconducting devices, MRI, infrared detectors and cryogenic electronics, the development of high efficient and reliable 10 K G-M refrigerator is of critical importance and awaited by cryogenic industries. In the past two years, systematic studies have been carried out, and detailed experimental tests indicated that the cooling performance of the 10 K G-M refrigerator was improved by adding two additional rectification meshes inside the low temperature regenerator and by optimizing the system charge pressure. Furthermore, a new labyrinth sealing displacer was proposed and fabricated to substitute the traditional piston-ring sealing displacer for improved operating stability and reliability of the 10 K G-M refrigerator. The detailed experimental results and improvements were summarized and their optimal cases were given in this paper.
