摘要

为解决能源利用浪费大、效率低、环境污染严重的问题

设计了一套脉动热管型相变蓄放热装置

搭建了实验台

考察了冷却水初始温度、冷却水流量和抽真空充液对脉动热管放热过程的影响

并计算了不同工况下脉动热管蓄热装置的热回收率。结果表明:冷却水初始温度越高

装置放热时间越长

水槽内冷却水最终温度也越高;冷却水流量越大

放热时间越短

但当冷却水流量增大至一定值时

总放热时间几乎不再变化;脉动热管是否抽真空充液对装置的放热性能影响不大;装置的热回收率随着冷却水初始温度的升高而降低

随着冷却水流量的增大仅有小幅增加。

Abstract

To solve the problems of energy waste

low efficiency and serious environmental pollution

a pulsating heat pipe type phase change storage device was designed and a test bench was set up.The effects of initial cooling water temperature

cooling water flow rate and evacuation filling on the exothermic process of pulsating heat pipe were investigated.The heat recovery rate of pulsating heat pipe heat storage device under different operating conditions was calculated.The results show that

the higher the initial temperature of the cooling water

the longer the heat dissipation time of the device is

and the higher the final temperature of the cooling water in the water tank is.The greater the cooling water flow

the shorter the heat release time

but when the cooling water flow increases to a certain value

the total heat release time almost has no change.Whether the pulsating heat pipe is vacuumed has little effect on the exothermic performance of the device.The heat recovery rate of the device decreases with the increase of the initial temperature of the cooling water and only slightly increases with the the cooling water flow rate.
