  • Publication number: 20240132997
    Abstract: A device for preparing ultra-high purity zinc based on intelligently-controlled zone melting, including a slide platform connected with a screw through a servo control system to control movement of a heating-cooling device. A quartz tube is provided inside an induction heater to protect a melting zone. An infrared thermometer is connected to the heater, and configured to monitor temperature within the melting zone, and control power of the heater. A ring magnetic stirrer with non-contact circumferential rotation cooperates with coil to stir zinc melt. A water-cooling copper jacket is connected to two ends of the heater to cool a zinc bar, and its water inlet and outlet are connected with a water chiller. The infrared thermometer monitors temperature of the zinc bar and controls water flow of the cooling system. A lifting device is connected with a base cabinet to change inclined angle of the zinc bar.

  • Publication number: 20240117470
    Abstract: A high-thermal conductivity composite material is AlNp/ZA27 composite material, including 2%, 4%, 6%, or 8% by volume of aluminum nitride (AlN) ceramic particles and zinc-aluminium-27 (ZA27) alloy. The ZA27 alloy includes 70.52-71.08% by weight of Zn, 25.58˜27.65% by weight of Al, 1.27˜3.45% by weight of Cu, and 0.50% or less by weight of Mg. In the preparation of the high-thermal conductivity composite material, an as-cast AlNp/ZA27 composite material is subjected to homogenizing annealing and reciprocating extrusion.

  • Publication number: 20230038051
    Abstract: A data transmission method and apparatus are provided. The data transmission method is applied to a computer system including at least two coprocessors, for example, including a first coprocessor and a second coprocessor. A shared memory is deployed between the first coprocessor and the second coprocessor, and is configured to store data generated when subtasks are separately executed. Further, the shared memory further stores a storage address of data generated when a subtask is executed, and a mapping relationship between each subtask and a coprocessor that executes the subtask. Therefore, a storage address of data to be read by the coprocessor may be found based on the mapping relationship, and the data may further be directly read from the shared memory without being copied by using a system bus. This improves efficiency of data transmission between the coprocessors.
