摘要
This work presents the recovery of thermal energy through the oscillation of liquid plugs induced by phase transition within the oscillating heat pipe (OHP) during the quick heat-transfer process of the OHP. Using the electrical double layer at the liquid-solid interface in the OHP, this study demonstrated that the waste heat can be recycled and converted into useful electric energy. This recycling system generated more than 1 V of output voltage and more than 1.6 μW of peak power. The electric output generated from such a process can be used to power up small electronic devices, such as capacitors and light-emitting diodes (LEDs). The findings in this work provide an alternative approach to harvest waste heat in many devices or systems that involve the generation and removal of waste heat.
