In order to analyze the factors which affect the start-up performance of plate pulsating heat pipe

a plate pulsating heat pipe with parallel trapezoidal channel was experimentally investigated in the forced air convection cooling conditions. Results indicate that heat pipe start-up behavior at low heating power are temperature rise steadily and jump

and the jump case is divided into two categories: the temperature of evaporator and condensation rise steadily and gradually declined; while heat pipe start-up behavior at high heating power is mainly temperature jump. In addition

the full start-up temperature of heat pipe rises with the increased liquid filling ratio and inclination angle

it has nothing to do with the heating power. Specially

heating power influences the start-up speed. The higher heating power leads to the faster heat pipe start-up.
