The invention provides a process for connecting a heat pipe and a partition plate of a titanium heat pipe type heat exchanger, a sleeve is arranged between the heat pipe and the partition plate, and a mounting hole is formed in the partition plate, the process for connecting the heat pipe and the partition plate of the titanium heat pipe type heat exchanger comprises the following steps: S1, preparing the sleeve; s2, welding is conducted on a first welding seam between the sleeve and the pipe shell of the heat pipe through a pulse TIG welding technology; s3, preparing a heat pipe; and S4, welding is conducted on the second welding seam between the sleeve and the partition plate through the vacuum electron beam welding technology. According to the connecting technology for the heat pipes and the partition plates of the titanium heat pipe type heat exchanger, the arrangement distance of the heat pipes can be remarkably reduced, the pipe arrangement density can be improved, then the heat exchange performance is
