This invention discloses a low-dissipation biomimetic microchannel network system and its manufacturing method based on fluid-structure interaction (FSI), belonging to the field of high-efficiency thermal management and microfluidic transport technology. Addressing the technical challenges of existing microchannels where surface roughness after additive manufacturing leads to a dramatic increase in pressure drop, and the inability of conventional mechanical polishing to handle complex three-dimensional blind cavities, this invention proposes a system deeply coupled with topological structure and rheological polishing.
