More Information
Summary:The utility model discloses a resistance-sharing and current-sharing device preventing metal tube bundles from abrasion, which relates to the abrasion prevention field for metal bundles brushed by airflows with dust as for boilers and heat exchangers or during other industrial process. The utility model comprises an inward concave curved face (1), an outward convex curved face (2), a windward curved face (3), a plane (4), a bent plane (5), a bent curved face (6), a connective plane (7) and an extending section (8); and cooperates with the outer surface of metal bundles. The utility model enables resistance balance for the whole gas channel and eliminates gas corridors, which protects metal bundles inside the gas channel effectively; meanwhile the utility model has simple structure and has no special requirements to metal materials, which provides much convenience for processing and assembly; no additional value is to be added to the new boilers and low cost is required to improve old boilers.
