对流

It builds the whole liquid-cooling system mainly by the design of the liquid-cooling decalescence boxes(improve its bottom material from aluminium alloy to pure copper, enlarge its volume, better cooling effects, and strengthen pressurization), by the operations of cooling effect about the heat exchanger worked by its temperature adjustability of the ribs(diffuse the heat fleetly owing to the excellent diathermancy of the material of the ribs ,make effective diathermancy owing to ribs outside areas, and drive the heat of the ribs away by the fans), and by the water pump made up of the piezoelectric ceramic with the excellent performance-no electromagnetism interference, little cubage, little noise, light exterior, light weight, low consume, high flux, replacing the mechanical pump.

在液冷散热器的研究中，主要通过对液冷吸热盒设计不断地改进(使吸热盒底部的材料从铝合金变为纯铜材料，其整个体积有所变大，但其散热效果明显变好，且密封性得到了极大地加强)，综合地运用换热器中肋片的壁面温度调节作用产生的散热效果(肋片材料优良的导热性，快速地扩散了热量：肋片较大的与流体接触的表面积，使传热更加充分，对流热阻大大减小；再利用风扇对肋片上的热量进行吹散)，利用性能优良的压电陶瓷泵(该泵机电性能稳定，具有无电磁干扰、体积小、噪音小、外型轻薄、重量轻、低能耗。、高扬程等优点。)代替机械泵作为驱动源，搭建了整个散热系统。
