摘要： The present invention relates to a method for manufacturing a two-phase flow heat sink. The two-phase flow heat sink comprises an evaporation chamber and a capillary layer. The material of the capillary layer, which has at least a porous structure, is cooled and disposed on the inner side of the evaporation chamber from a melted state. The method first sprays the thermally melted material of the capillary layer on the substrate of the evaporation chamber for forming the capillary layer on the substrate. Because the capillary layer is sprayed on the substrate of the evaporation chamber, the capillary layer is distributed irregularly on the substrate and forming irregularly distributed holes. Thereby, the flowing space for fluids in the evaporation chamber is increased, and hence enhancing the heat transfer efficiency of the heat sink.
