Heat pipe designs for thermal management: (A) graphene-based heat pipe which provides heat dissipation capacity of 7230 W m −2 K −1 g −1, about 3.5 times higher than that of copper-based commercial heat pipes [124], (B) infrared illustration for heat transfer of a thin loop heat pipe under the steady state operation developed by Fujitsu ...
Design and performance evaluation of pulsating heat pipe using …
2024年1月1日 · Most heat pipes depend on the capillary force enabled by their wick structures for heat transfer from evaporators to condensers. However, pulsating heat pipe (PHP) first proposed by Akachi [14] is a wickless heat pipe. The pressure imbalance between evaporator and condenser sections is the driving force for the fluid flow inside a PHP.
