结霜等截面环肋传热特性

Heat transfer character of frosting circumferential fin of rectangular profile

通过适当假设,推导出了结霜等截面环肋传热的数学模型,然后得到其传热热问题的修正解,同时给出其相应的热流量计算公式。与一般简化的肋传热计算公式相比,该解提高了计算精度,并且表达形式简单,可以很方便的应用于工程实践;对结霜肋片的设计有一定的理论指导作用,并可以推广到其他类似的传热等问题中。

Through the appropriate assumptions,The mathematical model was derived in circumferential fin of rectangular profile,and then its modified conduction solution was amended,and the corresponding heat flow calculation formula was given.With the original formula,this solution enhance the accuracy and simple form of expression,can be easily used in engineering practice.Frosting fin on the design of a theoretical guide.and it can be extended to other heat transfer problems of fin.
