提出了一种新型紧凑式换热器--双螺旋换热器。首先，传热系数的行为是定量确定通过热交换器中的热和冷水流之间的热交换的实验。随后，热接收器的水被改变与相变材料（PCM）-水浆料，以确定PCM熔化的传热强化的效果，通过直接测量的传热速率。通过适当地评估与PCM熔融浆料的物理性质，我们最后提出了一个传热关联，这是适用于水和浆料流动。
Double-spiral-type equipment is proposed as a new compact heat exchanger. Initially, the behavior of heat transfer coefficients is quantitatively determined through experiments of the heat exchange between hot and cold water flows in the exchanger. Subsequently, the heat-recipient water is changed with phase change material (PCM)–water slurry to ascertain the effects of PCM-melting on heat transfer enhancement through direct measurements of heat transfer rates. By appropriately evaluating the physical properties of the slurries with PCM-melting, we finally propose a heat transfer correlation which is applicable to both the water and slurry flows.
