Research on Heat Transfer Characteristics of Air Cooling Plate Embedded with Heat Pipes

The influence of air supply mode, input air amount and embedding heat pipes on air cooling plate heat transfer characteristics was investigated by using CFD techniques. An air cooling plate embedded with heat pipes was manufactured and experiments were done in order to validate simulation conclusions. Both the simulation and experimental results indicate that the temperature uniformity of the crossing flow plate is apparently improved compared with that of syntropic flow plate, which is 4–8 ℃ and 20–30 ℃, respectively. Moreover, the maximum temperature and temperature uniformity are both improved with the increase of air supply velocity and embedding with heat pipes. This study is referential for thermal design of air cooling electron equipment.
