Experimental Study on the Homogenization Performance of Flat Plate Pulsating Heat Pipe with Heat Storage Type

In order to realize the equalization and heat dissipation of local high heat flow density heat source of 5G equipment, this paper designs a heat storage type flat plate pulsating heat pipe heat sink, and studies the temperature of the heating surface of the pulsating heat pipe and the equalization performance of the cooling surface by changing the conditions of the heat storage medium, the filling rate of the liquid, and the heating position, etc. The experimental results show that: the filling of the heat storage medium can slightly strengthen the heat transfer and the equalization performance; the startup of the heat pipe can greatly enhance the heat transfer capacity and equalization capacity of the cooling surface; the change of the heating position has a great impact on the startup of the heat pipe, and the arrangement of the heating position in the heating surface is in the middle of the lower part of the control of the overall temperature of the heat pipe and the improvement of the equalization performance of the best effect.
