[Haichuan Chemical Technical Documentation] How to calculate the heat exchange area of the coiled tubes inside a storage tank? The complete calculation pathway from ΔTm and K values to coil diameter and number of turns: Tanks equipped with coiled tubes (immersed coil heat exchangers) can easily heat or cool the fluid inside the tank, and are widely used in the chemical, petrochemical, and food and pharmaceutical industries. This article provides a systematic analysis of the typical structure of internal coil storage tanks and the key aspects of coil arrangement, focusing on the core logic behind heat transfer calculations: how to determine the heat load, calculate the critical and error-prone overall heat transfer coefficient K, select the logarithmic mean temperature difference ΔTm, and ultimately determine the heat exchange area and coil dimensions. At the end, two practical examples of heating and cooling are used to fully demonstrate the calculation process, along with an introduction to calculation tools that can improve efficiency.
