The application of a TEG (thermoelectric power generator) to harvest energy from the waste heat of a commercial table lamp was investigated experimentally as well as numerically. The table lamp was integrated with TEG chips which were cooled by a natural convection heat sink. In the simulation,...

A new type of thermoelectric generator (TEG) system based on liquid metal which serves to harvest and transport waste heat, is proposed in this paper. To demonstrate the feasibility of the new TEG system, an experimental prototype which combined commercially available thermoelectric (TE) modules...

A new type of open-cell metal foam-filled plate heat exchanger based thermoelectric generator system (HE-TEG) is proposed to utilize low grade waste heat. This system can realize waste heat recovery through heat exchange and thermoelectric (TE) power generation. An experimental prototype is...

Thermoelectric generator (TEG) is a promising energy conversion device for vehicle exhaust waste heat recovery. Although TEG is desired to work under composite modes and operating conditions, the influence of start-up mode on the performance of TEG was rarely paid attention to. In this study,...

This paper presents the modeling and model validation for a modular two-phase heat exchanger that recovers energy in heavy-duty diesel engines. The model is developed for temperature and vapor quality prediction and for control design of the waste heat recovery system. In the studied waste heat...

The industrial waste heat parameters, like flow rate and temperature, usually fluctuate in a certain range due to the variation of upstream industrial process. However, the heat recovery systems are usually designed not under the fluctuation range but under a specific point, therefore, the most...

Three billion people cook using traditional fires, and exposure to smoke from cooking remains a persistent and significant environmental health risk factor: household air pollution is estimated to cause 3-4 million premature deaths per year. "Improved cookstoves" could reduce the health risks...

Purpose of this paper is to compare the performance of an alkali metal thermal electric converter (AMTEC) and thermoelectric generator (TEG) as a subsystem for utilizing rejected heat from the molten carbonate fuel cell (MCFC). AMTEC and TEG have various advantages such as; higher power density,...
