Air-Side Heat Transfer in Louvered Fin Heat Exchangers

Louvered fin 열교환기(熱交換器)의 공기측(空氣側) 열전달(熱傳達)

A study has been conducted experimentally on heat transfer characteristics of the heat exchangers with louvered fins in air. The experimental results are as follows; 1. Mean heat transfer coefficient is decreased with increasing temperature difference and model III is the best at constant temperature difference. 2. Pressure drop is increased with increasing air velocity, but it is decreased as the heat transfer area increases. 3. $\bar{h}/^{\Delta}p$ is increased and then decreased as air velocity increases.
