ABSTRACT = {The field synergy principle and thermal resistance analysis were carried out for the heat transfer enhancement of a chip heat sink. Thermal analysis of 
the heat dissipation capacity is applied for setting up the gallery on the rib, changing the fan ventilation diameter, and changing the rib height. The 
results show that the analysis of field synergy principle agrees well with that of the thermal analysis, and setting up a gallery on the rib can improve 
the heat capacity of the heat sink. Meanwhile, the results also show that decreasing diameter of the ventilation causes heat capacity dropping because 
the reverse flow area increases and the air flow rate reduces. Furthermore, the rib height plays an important role in the flow path geometry, and it has a 
significant effect on the convective heat transfer coefficient.},
