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 (0.05~0.10 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 channel length, width, and the collecting pipe insertion depth. The factors affecting the fluid distribution uniformity 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.
