在节能领域,利用相变来传递热量是提高余热回收率的有效手段,但是,相变本身也存在强化这个问题。例如,在回收低温余热,或者利用地热能发电时,参加相变的工质是有机工质,由于有机工质的沸腾和凝结换热系数都比较小,因此相变侧的热阻就比较大,这时,对相变传热的强化就显得特别重要。本文将讨论和分析国内外各种相变传热强化方法的 In the field of energy saving, the use of phase transition to transfer heat is an effective means to improve the recovery of waste heat, but the phase transition itself also has the problem of strengthening. For example, the recovery of low temperature waste heat, or the use of geothermal power generation, participate in the phase transition of the working fluid is an organic working fluid, the organic refrigerant boiling and condensing heat transfer coefficient is relatively small, the phase transition side of the thermal resistance is relatively large At this time, the strengthening of phase transition heat transfer is particularly important. This article will discuss and analyze various phase transition heat transfer enhancement methods at home and abroad
