This paper presents experimental results of friction factors for air flow in micro rectangular channels with different aspect ratios and with d}, of 0.2￣1.1 mm at different wall temperatures. The results show that the air flow can be divided into four flow regions f laminarflow, transition flow, turbulent flow and accelerating flow regions. The range of each region is different from that for macrochannel. For the later three regions, variation of friction factor has new features, and for the laminar flow region, the friction factor is about the same as that for a macrochannel.
