摘要

为了研究脉动热管对相变蓄热装置传热能力的优化，设计并搭建了脉动热管相变蓄热装置试验台，实验验证相变潜热蓄热量远大于显热蓄热量；在相同工况下改变加热流体流量，流量增大对传热优化有一定作用，但流量不宜过大；调整热源温度，温度越高，相变蓄热过程所需要的时间就越少；与常规铜管进行蓄热实验对比，脉动热管相变蓄热装置在蓄热过程中节省了47%的蓄热时间，同时优化了相变蓄热装置的传热均匀性。实验证明利用脉动热管技术对相变蓄热系统进行传热优化是可行的。

Abstract

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.
