At present, the sealing test of water-cooled radiators of new energy vehicles in China mostly adopts the artificial water tank testing method with low precision, poor craftsmanship and high labor intensity.In order to provide manufacturers with more accurate and efficient testing methods, Hirays Technology has developed a new energy vehicle water-cooled radiator sealing tester.

The water cooling system consists of a water pump, radiator, cooling fan, thermostat, compensation bucket, engine block, water jacket in the cylinder head, and other ancillary devices.Complex internal components lead to high detection risks and high costs.In order to solve these problems, Hirays Technology has applied the principle of air tightness detection to the water-cooled radiator sealing tester of new energy vehicles.

This new energy vehicle water-cooled radiator sealing tester uses compressed air as the testing medium, and the pressure drop test method is used to test the air tightness.For the sealing testing principle of new energy vehicle water-cooled radiators, Hirays Technology mainly formulates a tooling mold based on the product, and then inflates the tooling mold during testing. If leakage occurs, the internal components will not be damaged, reducing testing costs and risks.In addition, there is only a very small internal space (1.5CC) left in the instrument, providing the best environment for testing.

At present, the minimum resolution of this detector can reach 0.01pa , supports leakage test methods such as leakage test, obstruction test, positive pressure test, and negative pressure test. The leakage test range is -40kpa~150kpa. Within this range, users can choose according to their own testing needs.

In order to improve the detection efficiency, the detector system is equipped with 8 basic test modes and more than 200 groups of subroutines, which can be selected individually or combined.Using 24-bit A/D conversion, 32-bit CPU operation, and full-touch human-computer interaction interface, it fully meets the automation standards for sealing inspection of water-cooled radiators in new energy vehicles.In addition, it is also equipped with a highly sensitive pressure sensor and a stable data statistics system. Each product detection only takes a few seconds. The detection results will be digitized and fed back to production, providing accurate data reference for the improvement of later production processes.

The considerate functions of Hirays Technology's new energy vehicle water-cooled radiator sealing tester have been recognized by many manufacturers and have been put into production testing in large quantities.
