Technical Field
[0001] The utility model relates to the technical field of automobile parts manufacturing, in particular to a split-type warm air helium inspection fixture. Background Art
[0002] Traditional methods for leak detection of heat exchanger cores all use water detection, dry detection, and helium detection. All of them require the inlet and outlet of the heat exchanger to be sealed and clamped before leak detection. If the inlet and outlet of the heat exchanger are flat or there is no clamping position, it is necessary to weld a regular pipe transition. The docking position between the vehicle manufacturer and the heat exchanger also needs to be regular and clampable. The heater core has a long welded pipeline, so the number of boxes in the package is small, resulting in a high transportation cost. When performing helium leak detection on a single core, the existing leak detection joints cannot be used to clamp it because the docking pipe position is irregular. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a split warm air helium detection fixture with a simple structure and easy operation. It can realize quick clamping of products and does not require through-type modification of the vacuum box. It can detect leaks in a single warm air core and realize separate packaging and transportation of the core, thereby reducing transportation costs and effectively solving the problems in the background technology.
