In the paper the new experimental data are presented to study the gas-liquid flow in minichannels with a thickness of 1 mm and 1.2 mm in isothermal conditions. The design (fluid input conditions) and the width of the channels were changed. The boundaries between the patterns of the gas-liquid flow were determined. Gas-liquid flow regimes maps were created. The patterns of a gas-liquid flow and transition between flow patterns were analyzed in detail. It made possible to find out the features of the gas-liquid flow in the solar collectors minichannels.
