Abstract
A new kind of louvered fin structures with staggered holes is proposed,
numerical simulation is carried out to study the heat transfer factor and
the friction factor, and an experiment is designed to verify the simulation
results at different Reynolds numbers, a good agreement is observed.
Comparison with the traditional louver structure reveals that when the
Reynolds number is between 150 and 400, the heat transfer factor increases
by 10~24%, the friction factor increases by 1~2%, and the comprehensive
evaluation factor increases by 9~23%. These results can be used for
optimization of louver finned heat exchangers.
