Representative value of thermal conductivity for wickless heat pipe in a thermoelectric generator system via computational numerical analysis / Nur Faranini Zamri, Ahmad Nidhol Rahin and Muhammad Hadrami Hamdan

Thermoelectric generator (TEG) cells are capable of producing electricity from the flow of heat through semiconductor materials via the Seebeck effect. A TEG module (TEM) was developed through the integration of TEG cells, heat pipes, and heat sinks with the function to recover low-temperature waste...
