This application relates to an air-gap thermal switch and its fabrication method. The air-gap thermal switch includes: a hot-end conductor; a hot-end support shell coaxially connected to the hot-end conductor; a cold-end conductor opposite to the hot-end conductor and with a gap between them; a cold-end support shell coaxially connected to the cold-end conductor and coaxially connected to the hot-end support shell; and an adsorption pump, wherein the hot-end conductor, hot-end support shell, cold-end conductor, and cold-end support shell form a closed cavity, and the adsorption pump is connected to the closed cavity. The air-gap thermal switch of this application includes a hot-end support shell and a cold-end support shell, which shortens the processing length of a single support shell and reduces the processing difficulty of thin-walled and slender shells. During the fabrication process, it can detect whether the hot-end conductor and the cold-end conductor are in contact, improving the fabrication success rate. The welding and sealing of the hot-end support shell and the cold-end support shell are achieved by laser welding, resulting in a small heat-affected zone and minimal welding deformation, improving the coaxiality and gap accuracy after welding.
