Abstract: With the rapid increase in the power consumption of global data centers, it is becoming more and more important to reduce the power usage effectiveness (PUE) value, which is a key metric for evaluating the energy efficiencies of data centers. The previously proposed advanced thermal management methods can make PUE values very close to 1. To further reduce the PUE of the air-cooled data center, a novel looped heat pipe (LHP) and thermoelectric generator (TEG) coupled system based on a series–parallel scheme was first proposed. Attributed to the passive heat dissipation apparatus with extremely low thermal resistance and high-efficiency thermoelectric power generation devices as adopted in this design, the power output, especially the net power output, could be greatly improved compared to the power outputs achieved in previous research, and an electrical power of more than several watts was obtained while cooling a server CPU, which enable servers possibly with PUE values less than one. The results showed that, under the condition that the junction temperature was below 85 °C, by using nine 40 mm TEGs, the minimum PUE of 0.997 was achieved at a Reynolds number of 930 and a heat load of 155 W.
