Abstract The defrosting behaviors and performances of super-hydrophilic, bare, and super-hydrophobic surfaces were experimentally investigated along different frost layer densities on a vertical plate. The defrosting behavior can be divided into three types based on the size of the water permeation layer. The defrosting behaviors of bare and super-hydrophilic surfaces were similar, whereas the super-hydrophobic surface behaved differently by allowing the frost layer to be easily removed from its surface. Defrosting performance was evaluated based on defrosting time and water retention ratio. Within the low frost layer density range, defrosting time did not depend on surface characteristics. However, as the density of the frost layer increased, defrosting time increased in the bare and super-hydrophilic surfaces, whereas in the super-hydrophobic surface, that time tended to decrease rather than increase. Water retention ratio was highest on the super-hydrophilic surface and lowest on the super-hydrophobic surface in all frost layer densities. Therefore, the defrosting performance of a super-hydrophobic surface was outstanding over a wide range of frost layer densities.

不同润湿性表面的垂直板除霜行为和性能

摘要 在垂直板上沿不同霜层密度对超亲水、裸露和超疏水表面的除霜行为和性能进行了实验研究。除霜行为根据透水层的大小可分为三种类型。裸露和超亲水表面的除霜行为相似，而超疏水表面的除霜行为则不同，因为它允许从其表面轻松去除霜层。根据除霜时间和保水率评估除霜性能。在低霜层密度范围内，除霜时间不取决于表面特性。然而，随着霜层密度的增加，裸露和超亲水表面的除霜时间增加，而在超疏水表面，该时间倾向于减少而不是增加。在所有霜层密度下，超亲水表面的保水率最高，超疏水表面的保水率最低。因此，超疏水表面的除霜性能在较宽的霜层密度范围内表现出色。
