The mal-uniformity phenomenon of plate heat exchanger has not disclosed clearly. This work enhances the 3D modeling of corrugate channels of brazed plate heat exchanger completely, covering geometry in inlet and outlet distributor zone. The full acrylic corrugated channel is as test section used as validator, tested in two-phase flow mode in order to track the flow distribution clearly. It is revealed that the mal-uniformity is generated by geometry of inlet and outlet distributor zone for single phase flow and it tend to be promoted by flow pattern, buoyancy effect as well as geometry of inlet and outlet distributor zone for two-phase flow.
