摘　　要：随着电子元器件和雷达等设备功率密度的不断提高,传统的散热方式越来越难以满足要求,而喷雾冷却因其更强的散热能力在高热流密度散热领域受到广泛关注。文中基于喷雾冷却技术设计了一种集成微型旋流雾化喷嘴的喷雾冷却冷板,并通过一套自行设计的喷雾冷却热性能实验系统研究了冷板的换热性能及其影响因素。该喷雾冷却冷板可实现超过100 W/cm^2高热流密度的散热能力,为未来雷达电子设备的冷却设计提供了新的思路,有着较好的应用前景。With increase of the power density of electronic chips,large radar and other equipment,the conventional heat dissipation methods are more and more difficult to achieve the desired thermal control requirements.Spray cooling has attracted widespread attention due to its advantages in high heat flux removal.In this paper,a cold plate with micro pressure swirl nozzles is designed based on spray cooling technology.The heat exchange performance and its influencing factors of the cold plate are researched through a set of self-designed spray cooling thermal performance test system.The maximum critical heat flux of this cold plate is above 100 W/cm^2.It provides an innovative design choice for future electronic equipment cooling and has good application prospects.
