Mobile phones can also be used, along with Internet software—for thermal calculations of coils submerged in a constant-temperature bath.

The last edit to this post was made by wiseboy on 2015-11-9 at 16:55. To put it simply: a certain amount of heat transfer fluid (or water, etc.) is placed in a container; an electric heating element or other means is used to heat the heat transfer fluid, maintaining a constant temperature (for example, 180°C). Then, the coil is submerged in the heat transfer fluid, with the material to be heated flowing through the coil. The core of this issue is calculating the coil size (specifications and length) and heating power. Such problems are encountered frequently, with countless people asking Hai Chuan. How to calculate it? Try opening the website below directly; the problem will be solved easily (password: 18400101): http://www.htcsoft.com/myapp/shuiyu.htm
Just updated: spiral coils, U-tubes, and straight tubes are all available.
Hello, Wiseboy moderator. I have a question: the unit of the dirt coefficient is a bit strange； 2 If the material is a gas, and its density changes continuously as the temperature rises, is it acceptable to use the average value at the inlet and outlet instead? Thank you very much
1. The unit of the dirt coefficient was incorrect; it has been corrected ； 2. It is possible to use the properties at the average temperature.
