A Review on Applications of Peltier Devices

Abstract

This paper presents a study on the recovery of waste thermal energy using thermoelectric modules for application in vehicles that could benefit from the generation of a small amount of electric current. A large amount of energy is wasted within the engine and in car cooling, energy that could otherwise be recovered by thermoelectric effect. Thermoelectric device is a solid-state active heat pump which transfers heat from one side of the device to the other side against the temperature gradient (from cold to hot), with consumption of electrical energy, also known as Peltier device. The conclusion appears really attractive economically and energy cogeneration using thermoelectric modules is totally clean.
