Very little, cause heat exchange unevenly and heat transfer effect is bad, similarly, the angle between adjacent fins 12 cannot be too small, too small
Words cause fin distribution too close, and flow resistance increases, and the caliber of air outlet passage 4 and pipeline 9 is not much different, but he
Differ greatly with the exchange capability of heat of homalographic, therefore heat exchange is uneven in such cases, causes heat transfer effect bad.Therefore it needs
Optimal size relationship is determined by a large amount of numerical simulation and its experiment.
