On September 8, Sirui New Materials (stock code: 688102) disclosed its invention patent titled 'Metal-Based Diamond Composite Heat Sink and Its Fabrication Technique,' with the application publication number CN122719451A. This innovative approach entails crafting a base plate from diamond particles, which are subsequently subjected to hot pressing and sintering alongside a transition metal layer billet to forge a composite substrate. Following this, additive manufacturing technology is harnessed to construct the flow channel layer, culminating in the creation of the heat sink. This cutting-edge technology delivers a multifaceted advantage, encompassing superior thermal conductivity, robust interfacial integrity, and unparalleled design flexibility for the flow channels.
