      Absorption chillers and two-phase cooling systems are widely used in nuclear reactors, thermal power generation, seawater desalination systems,
    etc.
    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
