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.
Claims18
An annealing apparatus, comprising:
- a hollow main body having a gastight periphery, wherein the hollow main body comprises an open inlet at one end thereof and an open outlet at the other end thereof;
- a conveying apparatus extending through the main body from the inlet to the outlet;
- a heating apparatus located along the conveying apparatus, the heating apparatus being oriented towards the outlet;
- and
- a gas grid to blow protecting gas into the main body, so as to form a gas screen inside the main body, wherein when the gas screen is in contact with the internal sidewall of the main body, two gas flows are formed to respectively flow towards the inlet and the outlet for exhausting, thereby oxidation gas in the main body is expelled from the inlet end the outlet.
