This paper analysis heat transfer and angular velocity of micropolar ethylene-glycol nanofluid over the triangular, rectangular and chamfer fins on the stretching sheet. The innovation of this paper is to investigate parameters of nanofluid flow passing from the different fins on the stretching surface. The finite Element Method is selected for solving governing equations. The nanofluid temperature in the space of fins is warm and equal to the surface temperature. The temperature value is ۳۰ degrees. The maximum values of nanofluid temperature exist in the last fin of surfaces. By passing the nanofluid flow from the first fins of the surface, the temperature of flow comes from ۲۵℃ to ۳۱℃  and at the ends of the surface, the temperature is high value. The maximum of ethylene glycol angular velocity occurs at x=۰.۹ for chamfer and rectangular modes and the minimum of temperature occurs at x=۰.۸ for ۳ different fins. The angular velocity for nanofluid on the triangular and chamfer modes is ۶.۵% bigger than other baffles.
