Abstract：The length,width and depth of insertion head of micro-channel heat exchanger were selected as investigation factors,then models were set up by using uniform design method,and sensitivity parameters that affected the uniform distribution of the micro-channel heat exchanger fluid flow were analyzed.The results showed that:1 )Micro-channel heat exchanger fluid distribution uniformity was not only associated with the state of the fluid flow,but also related to the structure and geometry;so keeping the lower flow rate(0.05 ~0.1 0 m /s)of the fluid micro-channel could be better for distribution uniformity.2)In the case that the inlet flow was constant,fluid flow distribution uniformity was the combined effect of the manifold results of the chan-nel length,width,and the collecting pipe insertion depth .The factors affecting the fluid distribution uniformi-ty in a descending order were the width of the micro-channel,the head insertion depth of micro-channel and the length of the micro-channel.
