A high thermal dissipation performance polyethylene terephthalate heat pipe has been fabricated and tested in this research. Polyethylene terephthalate (PET) is used as the container material instead of copper. Copper mesh and methanol are sealed in the middle of two PET films as the wick structure and working fluid. Although the thermal conductivity of PET (0.150.24 Wm·K) is much smaller than copper (401 Wm·K), the experiment results reveal that the PET heat pipe can reach a minimum thermal resistance of 0.146 (oCW) and maximum effective thermal conductivity of 18,310 (Wm·K) with 36.9 vol at 26 W input power. However, when the input power is larger than 30 W, the laminated PET will debond due to the high vapor pressure of methanol.
