A Review of Waste Heat Recovery Methods Using Thermoelectric Devices

Thermoelectric devices are developed for recovering waste heat and converting it to electrical energy. The conversion occurs when a temperature difference across a specific location in semiconductors generate a voltage potential. This review of waste heat recovery methods using thermoelectric devices addresses energy challenges, air pollution, and global warming. This study aims to discuss the various traditional and novel waste heat recovery methods known today. After review, it has been found that alternative models and different configurations of thermoelectric modules are feasible for use. Heat pipes and thermoelectric generators are effective for heat recovery and energy generation of energy recovery systems.
