The surface temperature of contact elements is one of the most important factors that influences the performance and life of tribological systems. Heat-pipe cooling seems to be a promising means for enhanced heat transfer. The heat input at the surface and the heat pipe as a heat sink represent a system of heat source/heat sink (HSHS). In this paper, the function of the heat pipe is mathematically described and the heat-transfer characteristics of the HSHS system are investigated. A semi-empirical model is developed to shed some light on the surface flash temperature control employing the HSHS system. Both steady-state and transient analyses show that heat pipes can be employed to reduce the flash temperature effectively. The possibility of applying this concept to composite materials is also analyzed.
