      Absorption chillers and two-phase cooling systems are widely used in nuclear reactors, thermal power generation, seawater desalination systems,
    Ensuring that the instrument maintains a stable working temperature is one of the important tasks of the cooling system

    Recently, researchers from Novosibirsk State University and the Institute of Thermophysics of the Russian Academy of Sciences have developed a new technology to improve the heat transfer efficiency of vacuum boiling, using this technology to develop a more efficient and reliable two-phase cooling system

    The related experimental results were published in Applied Thermal Engineering



      Immersion cooling system is a type of two-phase cooling system, the main principle is to maintain the desired temperature conditions by removing excess heat from the heating surface by means of liquid boiling
    The research team has developed a new double-helix exothermic surface that combines the advantages of both hydrophobic and hydrophilic properties, which can decompose large bubbles during boiling into multiple small bubbles, thereby ensuring uniform surface temperature

    This new technology can improve the heat transfer efficiency by 3.
    7 times, can also provide a stable cooling temperature range, and avoid the damage to the instrument caused by the obvious fluctuation of the heat transfer surface temperature during the boiling process
