利用热库、管径变化和增加肋片方法可控制集热板的冻结顺序。本文对其机理进行了讨论,并报道了以此原理设计和制作的新型抗冻太阳热水器的实验研究结果,表明利用顺序冻结原理进行抗冻是可行的。
The use of thermal storage, pipe diameter change and increase the fins method can control the collector plate freezing order. This paper discusses its mechanism and reports the experimental results of a new type of anti-freezing solar water heater designed and produced by this principle. It shows that it is feasible to use the sequence freezing principle to resist frost.
