Minichannel cooling systems show great potential for small scale electronics. In this paper we analytically and numerically investigate flow with evaporation in open triangular minichannels without upper gas flow. It models processes either in a groove or in an individual channel. From the laws of mass, momentum and energy conservation we derive equations for mean velocity and for the depth of the liquid. These equations have been solved numerically. The viscosity limits maximum fluid speed and causes the formation of dry spots. The heat flux reaches 40kW/m2 for initial liquid velocity 2 m/s. It is demonstrated that triangular or grooved channels even without upper gas flow are perspective for cooling systems.
