Multi-blade milling process of Cu-based microchannel for ...

A combined tool with stacked blades was developed to efficiently fabricate microchannel plates by using the multi-blade milling process. The microchannel plates with 0.632 mm in hydraulic diameter and 40 mm in length were then used to assemble the microchannel heat exchanger. The thermal performance of microchannel heat exchanger was experimentally investigated with different flow rates.
