Multi rectangular micro-channel evaporators is one of the promising technologies for cooling the new generation of electronic chips with high heat flux to maintain its safe temperature at low energy consumption.Where, it improves the heat transfer coefficient athigher mass velocities.The present study is directed to measure and evaluate the performance of a conventional microchanel evaporator (Case-1), orifice at inlet to microchanel evaporator(Case-2) and tree at inlet to microchanel evaporator (Case3). Where, the performance indicators are presented to compare between the proposedthree cases in terms of heat transfer coefficient, pressure drop and wall temperature. The results showed that,The highest record of heat transfer coefficient (h=109 KW.m-2.K-1) is obtained at mass flux of (G=900Kg.m-2.S-1) from case-3.
