摘　　要：针对某型雷达高功率且热流密度大模块,采用液冷强迫对流方式解决系统散热问题,分析了影响液冷冷板流量分布特性和散热特性的因素;基于搅拌摩擦焊技术的复杂流道焊接工艺,提出了三种流道结构形式冷板。依据单一变量原则,分别以流道宽度、深度、冷却液等效入口流速为变量,对不同流道结构冷板进行流动性及散热性研究,试验表明了为提高冷板流动性能和散热性能,应综合考虑冷板流道宽度、深度、冷却剂流速等因素影响;另外,O型结构冷板的综合流动性能和散热性能优于其他两种结构形式冷板。A iming at a dissipation problem that a certain type of radar module generated high power and larg~ heat, the way of forced convection on solid-liquid interface was taken and the influence factors of the flow and heat performance were analyzed. Based on the technology that complicated flow channels were welded by friction stir welding, three kinds of flow channel structure of cold plate were purposed. Under the principles of a single variable, different channel structure of cold plate was researched, respectively with width, depth and inlet equivalent velocity. The experiment results indicated that the influence factors of width, depth and inlet equivalent velocity should be fully considered to improve the fluidity and heat dissipation performance , while the performances of O-shape channel structure were better than other types of cold plate.
