Description

Technical Field

[0001] The invention relates to the field of liquid-cooled antenna panel processing, in particular to a large-size aluminum alloy liquid-cooled antenna panel maze plugging device. Background Art

[0002] Large-size aluminum alloy liquid-cooled antenna panels are widely used in antenna array structures of various electronic equipment due to their superior thermal conductivity, mechanical properties and efficient space utilization. As the core component of the entire liquid cooling system, large panels have very high requirements for channel size accuracy and cleanliness. The large-size liquid-cooled panel with flow channel consists of a large panel base plate and several cover plates. The cover plate and the base plate are welded by stir friction welding, and then post-weld stress relief heat treatment is performed to ensure the processing size accuracy of the large panel. The inlet and outlet of the large panel need to be blocked during machining, welding, heat treatment and turnover. It is necessary to ensure the cleanliness of the flow channel during the entire processing and manufacturing process, and to ensure that the hot air in the flow channel is discharged along the inlet and outlet during welding and heat treatment to prevent the formation of high pressure, which may cause the cover plate to bulge or warp during welding and heat treatment.

[0003] When similar large panel structures are processed, welded and heat treated at home and abroad, in order to prevent the formation of high pressure in the flow channel, generally no plugging device is used to plug the water inlet and outlet holes of the large panel, which makes it easy for various impurities to enter during processing, welding, heat treatment and turnover protection. Due to the complex shape of the flow channel of the large panel, it is difficult to clean the impurities once they enter. Therefore, it is necessary to invent a plugging device that can not only ensure the cleanliness of the flow channel during the processing and manufacturing process, but also discharge the hot air during welding and heat treatment to prevent the formation of high pressure in the flow channel cavity. At present, there are no patents and articles on large-size aluminum alloy liquid-cooled antenna panel maze plugging devices at home and abroad. Summary of the invention
