定态变温传热过程平均温度差的简化计算

A Simp1ified Calculation for the Mean Temperature Difference in the Steady一State Heat Transfer Process with Varing一Temperture

本文提出了一个计算定态变温传热过程平均温度差的简化公式：该式可替代对数平均温度差求解传热问题，无需试差，而且计算准确度高。

This paper presents a simplified calaculation formula for the mean tempera-ture difference in the steady一state heat transfer process with varing一temperature:The formula can be used to calculate the probelem in the heat transfer process to re-place the logarithmic mean temperature difference。It does not try again and again,andhas high accuracy。
