  • PANEL TYPE RADIATOR WITH REINFORCING RIBS AND COOLING FINS IN LINTEL WELDING
    Publication number: 20250244087
    Abstract: Provided is a panel type radiator with reinforcing ribs and cooling fins in lintel welding, which includes multiple cooling fins, two oil collecting tubes, multiple reinforcing ribs and multiple welding seams. Each cooling fin is formed by welding two cooling sub-fins oppositely arranged. An edge of a long side of the cooling fin intersects with an outer surface of the reinforcing rib, and a gap suitable for a lintel-shaped weld is provided at an intersection. A welding material droplet weld is formed between an outer edge at an attached position of the long side of the cooling fin and the outer surface of the reinforcing rib, and the shape of the weld is lintel-shaped. The lintel-shaped weld is divided into three regions. The welding material fusion welding connection lintel region is self-fusion welding metal of the welding material.

  • Permanent magnet electrodynamic suspension system and guidance method therefor
    Patent number: 11801756
    Abstract: A permanent magnet electrodynamic suspension system includes a conductor track and a suspension and guidance device. The conductor track is disposed on a roadbed, and the suspension and guidance device is disposed above the conductor track. The suspension and guidance device includes a first permanent magnet array and a second permanent magnet array. The first permanent magnet array and the second permanent magnet array are the same in the magnetization direction arrangement. The first permanent magnet array and the second permanent magnet array are arranged perpendicular to each other. A guidance method for the permanent magnet electrodynamic suspension system is further provided.
