摘　　要：以烧结铜粉为毛细芯的均温板作为实验对象,研究毛细芯结构参数、充液率、加热面积对均温板传热性能的影响,并与纯铜板进行性能比较.实验结果表明:粒径为90μm的毛细芯结构均温板传热效果最好,在充注率为90%情况下均温板性能最佳,大面积热源要远低于小面积热源下的均温板热阻值.在上下板之间烧结毛细芯柱,可大大缩短回液路径,减小回液阻力,从而减小均温板热阻.Sintered vapor chambers are designed and the manufacture process is explored.The effects of wick structure,filling ratio,and heating source area on thermal resistance are investigated,and compared with copper plate.It is found that the vapor chamber with a particle size of 90μm showed better dissipation performance.The best filling ratio for the tested vapor chamber was found to be about 90%.The vapor chambers heated by large area presented higher thermal resistance than those heated by small area.The wick column could shorten the liquid supply path significantly and result in lower thermal resistance of the vapor chamber.
