Abstract:
One of the important issues that increasing development of electronic systems has caused is how to transfer the generated heat out of the system. Heat pipes can transfer large amount of heat because of using latent heat of evaporation and condensation. In micro scales using micro heat pipes is popular that in this instrument liquid returns to evaporator by means of surface tension force. So numerical solution is essential for verifying experimental results and increasing performance of this instrument. In this research has been planned to develop a comprehensive model for numerical solution of flow and heat transfer in micro heat pipes. For this reason surface evaporation and …, disjoining pressure and …. Has been considered and finally distribution of velocity, pressure, temperature, etc and effect of parameters like contact angle, filling ratio, geometry, etc on performance of micro heat pipe has been studied
