Description

Technical Field

[0001] The utility model relates to the technical field of radiator core processing, in particular to a core air tightness detection device. Background Art

[0002] During the processing of the filter core, it will be partially welded according to the actual situation and then assembled as a whole. During the working process, in order to improve work efficiency, it is generally tested for overall air tightness after the overall assembly. For the later air tightness test, due to the continuity of the process flow, the parts with poor airtightness may be retrieved as the previous workpiece during the retrieval. Therefore, it is necessary to dismantle the previous workpiece to repair the leak and then continue to assemble. This form will affect the overall work efficiency and waste working time in the actual working process.
