ABSTRACT:
An annealing apparatus includes a gas tight hollow main body, a conveying apparatus and a gas grid. A heating apparatus and a cooling apparatus are installed at an inlet and an outlet of the main body, respectively. The gas grid is installed between the inlet and the outlet to blow the protecting gas into the main body, so as to form a gas screen. The conveying apparatus extends to the inlet and the outlet to convey process material such as heat pipe. Thereby, an open, non-pressure differential environment is established for performing annealing on the process material.
