摘要(Abstract):
设计了一套脉动热管相变换热装置,并在搭建的试验台上对不同倾角下脉动热管换热装置的总放热时间和相变潜热放热时间进行了试验测定。结果表明脉动热管相变换热装置在0°、30°、60°、90°倾角下,0°角冷却的放热总时间和相变潜热换热时间均最少,90°倾角下放热总时间和相变潜热放热时间最长。增大冷却水流量,总放热时间和相变潜热放热时间均会减小,但当冷却水流量达到一定值时,继续增大冷却水流量,总放热时间几乎不再变化。冷却水初始温度越低总放热时间和相变潜热放热时间均有较大减少,水槽内冷却水最终温度差别不大。
A pulsating heat pipe type phase change thermal storage device is designed and test bench is set up.At different angles of pulsating heat pipe heat exchanger,heat release time and latent heat release time is measured.Pulsating heat pipe phase change heat exchange device at 0 degrees,30 degrees,60 degrees,90 degrees angle,the total heat release time and latent heat transfer time of 0 degrees angle cooling are the least,the total heat release time and the latent heat release time of 90 degrees angle cooling are the longest.Increasing cooling water flow rate,the total heat release time and latent heat release time is decreased,when the cooling water flow reaches a certain value,continue to increase the flow of cooling water,the total heat release time almost never changed.The lower the initial temperature of cooling water,the total heat release time and the latent heat release time is decreased greatly,there is little difference in the final cooling water temperature in the sink.
