چکیده

In the present study, a firefly algorithm is used to achieve a multi objective optimization of heat pipe with axial “Ω” shaped micro grooves. The objective function of the optimization procedure is maximization of heat transport capability and minimization of the total thermal resistance. So the effects of geometrical dimensions and structural parameters on heat pipe performance have been considered as decision variables. Also heat transfer capability and total thermal resistance of heat pipe have been considered as objective function. The agreement between experimental data and calculated results confirms the accuracy of the proposed algorithm for micro groove heat pipe analysis .The effect of grooves number and vapor core diameter on heat transfer and total thermal resistance have been analyzed and it shows by increasing the number of grooves and core diameter, heat transfer capability and total thermal resistance increased. Heat transfer capability and total thermal resistance decreased by increasing width of slot. For equal in size width slot by increasing grooves diameter heat transfer and total thermal resistance respectively increased about 25% and 7%. Result shows working temperature significantly effects on the heat transfer capability and maximum heat transfer capacity occurred about 271 K.
