对现有东风４Ｂ型机车中冷器扁管强化板芯冲孔立刺强化板芯进行了传热传质比拟实验．实验结果表明：冲孔立刺强化板芯使传热增强，但阻力增加程度较大．在相同泵功率条件下，传热强化作用甚微．
The heat and mass transfer experiments were carried out on the existing Dongfeng 4B locomotive intercooler flat tube reinforced core punching stabbed reinforced core. The experimental results show that the punching stab-reinforced core strengthens the heat transfer, but the resistance increases a lot. In the same pump power conditions, heat transfer enhancement effect is minimal.
