提出一种低成本固相烧结制造多孔微通道的方法，设计3种多孔复合微通道，并通过优化烧结工艺，制备具有高孔隙率的多孔复合微通道。研究多孔复合微通道的流动阻力和传热性能。结果表明：在流动阻力可接受的范围内，传热性能显著增强，而且流动沸腾也得到强化。将多孔复合微通道结构应用在对流传热领域具有良好的前景。%A solid-phase sintering process for the low-cost fabrication of composite micro-channels was developed. Three kinds of composite micro-channels with metallic porous structures were designed. The sintering process was studied and optimized to obtain porous-structured micro-channels with high porosity. The flow resistance and heat transfer performance in the composite micro-channels were investigated. The composite micro-channels show acceptable flow resistance, significant enhancement of heat transfer and dramatic improvement of flow boiling stability, which indicates a promising prospect for the application in forced convective heat transfer.
