The concept of heat-driven self-cooling of devices is an important energy saving measure by which devices would be able to provide power to run cooling flow without external power supply. Thermoelectric generation device is proposed to convert the heat energy into electrical energy to drive a hydraulic pump of microchannel heat sink based single phase cooling system. The system could be made self-sustaining in terms of power requirement. In this paper, numerical modeling and validation have been conducted based on an experimental study of net power generation in liquid flow based microchannel heat sink. The relationship between coolant flow rate and heat flux at heat source device has been modeled to study the viability of self-cooling concept. It has been found out that at an optimum flow rate of cooling fluid, it is possible to keep the temperature of a heat source device at a required temperature while providing power to run the coolant through the microchannel heat sink.
