AI Technical Summary

Technical Problem

The lack of a forced guiding structure in the oil cooler causes impurities to form an uneven adhesion layer on the filter paper surface, resulting in early blockage in some areas. This affects the filtration efficiency and heat exchange effect of the oil cooler, and reduces the operational stability of the circulation system.

Method used

It adopts a forced guiding structure with an annular oil box, drive blades and telescopic oil drain pipe, combined with an arc-shaped limiting block, cleaning collar and cleaning scraper, to achieve forced directional injection of oil and cleaning of the filter element surface, preventing impurities from adhering.

Benefits of technology

This effectively avoids uneven adhesion of impurities on the filter element surface, reduces the risk of local blockage, maintains filtration efficiency and system stability, and improves the operational reliability of the oil cooler.
