To research actual effect of heat transfer enhancement on pulsating heat pipe of phase change heat storage device
a pulsating heat tube type phase change heat storage device was designed and set up. The phase change thermal storage device has obvious phase change heat storage process; latent heat of phase change heat storage capacity is much greater than the sensible heat storage. Heating fluid flow increases under the same conditions have a role about the heat transfer enhancement
but the flow is not too large. Adjust the heat source temperature
the higher the temperature
the less time required for the phase change heat storage process. Compared with conventional copper tube
the heat storage device of pulsating heat pipe has saved 47% of the heat storage time in the process of heat storage and the heat transfer uniformity of the phase change heat storage device is optimized. It is verified that the heat transfer enhancement of the heat storage system is feasible by using pulsating heat pipe technology.
