随着电子元器件小型化、集成化的要求，功率密度的迅速提高，传统的液冷式冷板已难以满足电子芯片日益增长的散热需求。本文提出了一种新型的紧凑型高散热喷雾冷却模块。采用微喷嘴和侧喷技术实现了喷雾冷却模块的小型化。在此基础上，设计并加工了一种微喷嘴喷雾冷却模块，其40%v. t.该系统以乙二醇和水为工质，喷淋冷却模块尺寸与常规冷板相同。分析了微喷嘴的喷雾特性，研究了多热源下冷板的传热特性。实验结果表明，微喷嘴的液滴主要集中在主流区，液滴速度较高，喷雾冷却模块的热流密度可达304.7 W/cm 2，多热源最大温差小于6.5 °C。这表明该喷雾冷却模块在高热流密度多热源的热管理中具有优势。
With the rapid increase in power density for miniaturization and integration of electronic component, the liquid-cooled cold plate, shows difficulty in meeting the increasing heat demand of electronic chips. In this paper, a novel compact spray cooling module with high heat dissipation performance is proposed. The miniaturization of spray cooling module is realized by micro-nozzle and side spray. Based on this method, a spray cooling module with micro-nozzle was designed and processed, both the 40% v.t. ethylene glycol coolant and water were used as working fluids in this system, the size of spray cooling module is the same as the conventional cold plate. The spray characteristics of the micro-nozzle was analyzed and the heat transfer characteristics of the cold plate under multiple heat sources were studied. Experimental results showed that the droplets of micro nozzle were mainly concentrated in mainstream region and the droplet velocity was relatively high and the heat flux of spray cooling module could reach 304.7 W/cm2, and the maximum temperature difference of multi-heat source was lower than 6.5 °C, which indicated that the proposed spray cooling module could show advantage in thermal management of high-heat flux multiple heat source.
