实验测定了用消失碳酸盐烧结法（LCS）制备的孔隙率为57%~ 82%、孔径为150 ~ 1500 μm的多孔铜的传热系数。将样品连接到加热板上，并组装到使用水作为冷却剂的强制对流系统中。通过多孔铜-水系统从热板的散热的有效性进行了测试，在不同的水流量从0.3到2.0 L/min和输入热通量为1.3 MW/m2。孔隙率对传热性能有很大的影响，最佳孔隙率为62%左右。与孔隙率相比，孔径对传热性能的影响要小得多。高水流速增强了所有样品的传热性能。
The heat transfer coefficients of porous copper fabricated by the lost carbonate sintering (LCS) process with porosity range from 57% to 82% and pore size from 150 to 1500 µm have been experimentally determined in this study. The sample was attached to the heat plate and assembled into a forced convection system using water as the coolant. The effectiveness of the heat removal from the heat plate through the porous copper-water system was tested under different water flow rates from 0.3 to 2.0 L/min and an input heat flux of 1.3 MW/m 2 . Porosity has a large effect on the heat transfer performance and the optimum porosity was found to be around 62%. Pore size has a much less effect on the heat transfer performance compared to porosity. High water flow rates enhanced the heat transfer performance for all the samples.
